Made In Space, Inc., the startup company out of Singularity University which, on Sept. 23, 2014, supplied the first 3-D printer to the International Space Station (ISS), has developed a program that it hopes will revolutionize construction in space, called the Archinaut Development Program.

Made In Space CEO Andrew Rush said: Its our ambition to develop the manufacturing technologies that will usher in the era of true commercial space utilization.

Using a combination of 3-D printing and robotic arms, the Archinaut project aims to develop small satellites which will be able to construct large structures in space.

The real difference maker for this technology is in the area of being able to put stuff up that you cant origami fold up, or that would be really, really difficult to do with a traditional deployable system, Rush said.

Rush explained that folding up structures so that they can survive launch prevents them from being truly optimized for space. Building them in space is a game-changer.

NASA selected Made In Space for its Tipping Point technologies in November 2015. Testing is under way at NASA Ames Research Center at Moffett Field in California, analyzing structures made by the 3-D printer aboard the ISS. The next phase will involve the use of robotic arms. The first phase of the project will last 18 months.

The second phase will involve the launch of a spacecraft which will demonstrate these techniques in orbit, building a structure a few meters across.

Archinauts Ulisses process uses a 3-D printer to manufacture parts from raw material stored in the satellites toolbox. Then robotic arms would assemble the structure. Raw material could come from asteroids or it could be recycled space debris.

Where this gets really interesting is, tens to 100 meters plus, Rush said. And thats what were angling toward.

One possible construction would be massive space telescopes. The structures could be manufactured in orbit using the 3-D printer, and then the lenses and mirrors, manufactured on the ground, could be integrated using robotic arms.

Rush points out that telescopes are not really space-optimized when theyre folded up in a nosecone for launch. A totally space-constructed telescope or any other structure would be unlimited in size and shape.

Made In Space is not the only company taking an interest in in-space manufacturing. Tethers Unlimited, a private aerospace company in Bothell, WA, plans on launching three experiments into space over the next three years.

Tethers Unlimited CEO Robert Hoyt said: The first scheduled flight experiment is the Refabricator recycling and 3-D Printing payload that will go up in 2018.

The Refabricator was developed by Firmamentum, a subsidiary of Tethers Unlimited. Developed with backing from NASA and the Pentagons Defense Advances Research Projects Agency (DARPA), it recycles plastic waste into raw material filament for 3-D printers to manufacture new parts.

After the Refabricator, the company plans on putting MakerSat into orbit a CubeSat that will be 3-D printed, assembled, and deployed aboard the ISS.

After that, Hoyt expects to launch the Dragonfly experimental satellites. Developed by SSL (formerly Space Systems/Loral, LLC), of Palo Alto, California, the Dragonfly satellites will be assembled on orbit.

SSL President John Celli said: NASAs Tipping Point program enables SSL to qualify new technologies for the commercial market while at the same time providing advances for future NASA missions.

Satellites assembled on-orbit using our integrated robotics capability will be capable of higher performance than satellites that can be launched today. An added benefit will be antennas that can be moved and changed during a satellites mission life for flexibility and to accommodate changing market requirements.

The ISS took ten years to build, requiring dozens of Space Shuttle flights hauling huge, cumbersome modules that had been constructed on Earth and required many spacewalks to assemble. These new technologies promise to eliminate such a complex and expensive construction process as well as making space manufacturing cheap, simple, and capable of building a true spacefaring infrastructure.

Launch of Falcon 9 rocket scrubbed second day in a row – Spaceflight Now

Updated at 4:30 a.m. EDT (0830 GMT) July 4.

For the second day running, computers automatically aborted a Falcon 9 launch countdown Monday at NASAs Kennedy Space Center in Florida in the final seconds before liftoff with the Intelsat 35e communications satellite.

SpaceX said its engineers will spend Tuesday examining data and reviewing systems before trying to launch again Thursday or Friday.

Out of an abundance of caution, SpaceX will be spending the 4th of July doing a full review of the rocket and launch pad systems, SpaceX said in a statement. The next launch opportunity for Intelsat 35e from Launch Complex 39A (LC-39A) at NASAs Kennedy Space Center in Florida is now no earlier than Wednesday, July 5 or Thursday, July 6.

SpaceX chief executive Elon Musk tweeted to confirm there will be no launch attempt Tuesday.

The trigger of Mondays abort was not immediately known, but an unplanned hold at the same point in a countdown Sunday was caused by a software error during a final check of the rockets guidance, navigation and control instrumentation.

SpaceX said they cleared that problem, and engineers pressed ahead with another attempt Monday to send the heavyweight nearly 7.5-ton Intelsat 35 relay and broadcasting satellite into orbit.

Stormy weather to the west of launch pad 39A at the Florida spaceport delayed the targeted launch time 58 minutes to 8:35 p.m. EDT Monday (0035 GMT Tuesday), the end of the days launch window.

Using a computer-controlled automatic sequencer, the launch team loaded the Falcon 9 rocket with super-chilled, densified RP-1 kerosene and liquid oxygen propellants in the final hour of the countdown.

No technical problems were noted by SpaceX engineers as the final minutes ticked toward liftoff, until the countdown stopped at T-minus 10 seconds. Without any time left in the launch window, the hold led to an automatic scrub.

Engineers will comb through data to determine source of the problem, and identify a fix, SpaceX said.

We have all the telemetry coming off of the rocket, so weve got plenty of information, but theyre taking their time right now to understand what system theyre really looking at that would be the cause of the hold, said John Insprucker, SpaceXs Falcon 9 principal integration engineer, who provided live launch commentary on the companys webcast.

SpaceX initially said it could try a third day in a row Tuesday Independence Day to launch the Falcon 9 rocket, but officials said a few hours after Mondays scrub that the next liftoff attempt would slip until later in the week.

We had an extended countdown today, Insprucker said as SpaceXs webcast signed off. We had to wait for the weather, and we got to T-minus 10 seconds before we had a hold, once again, called by the automated abort criteria.

We were not able to recycle because we were out of the window, he said.

SpaceX is going for its third Falcon 9 launch in less than two weeks, and the second from pad 39A in that span. The Air Force-run Eastern Range was expected to be unavailable for launch operations for a couple of weeks beginning soon after the July 4 holiday.

Intelsats senior vice president of space systems, Ken Lee, said additional engineers came to Cape Canaveral to prepare for the Intelsat 35e launch, and ground teams worked around-the-clock in shifts ahead of the Falcon 9s first launch attempt Sunday.

Once the Falcon 9 takes off with Intelsat 35e, SpaceXs launch cadence will slow for a few weeks. The companys next mission is scheduled to launch Aug. 10 from Florida on a space station resupply run.

Richard Branson targets space flights by mid-2018 as Virgin begins powered tests – Stuff.co.nz

BRUCE EINHORN

Last updated10:33, July 6 2017

Virgin Galactic/Facebook

Virgin Spaceship Unity glided for the first time in 2016 after being released from Virgin Mothership Eve above the Mojave Desert.

Richard Branson's Virgin Galactic is poised to resume powered test flights more than twoyears after the fatal breakup of its experimental rocket plane, with the billionaire entrepreneur aiming to make the first trip into space himself by the middle of next year.

Following the completion of a series of glide-only sorties, powered tests are set to take place every three weeks with the aim of extending them into space by November or December, Branson said in an interview. After his own flight, full commercial passenger operations should start by the end of 2018, he said.

Branson's update is the most detailed since the October 2014 crash of Virgin Galactic's original SpaceShipTwo, in which co-pilot Michael Alsbury died when the craft was torn apart after he prematurely unlocked a braking mechanism.

Sheriff's deputies look at a piece of debris near the crash site of Virgin Galactic's SpaceShipTwo near Cantil, California November 1, 2014.

While the accident in the Mojave Desert came just months before the planned maiden commercial flight, Branson said the appetite for travel to the edge of space remains undimmed, leaving room for a number of competitors.

"We will never be able to build enough spaceships," Branson said Wednesday in Hong Kong following the introduction of Virgin Australia flights from Melbourne. "The demand is enormous."

RADIO NEW ZEALAND

Richard Branson is one step closer to lift-off after Virgin Galactic secured an operating licence for space tourism.

Branson was an early leader in the new space race after founding Virgin Galactic in 2004. Since then, rivals like the Jeff Bezos-backed Blue Origin and Elon Musk's Space Exploration Technologies Corp., or SpaceX, have gained momentum by focusing on reusable rockets to cut the cost of space travel.

The Briton, who turns 67 on July 18, said there's a role for various launch systems, especially in the deployment of satellites, viewed as a likely mainstay of Virgin Galactic's future business.

The company's Virgin Orbit arm is working on a two-stage air-launched rocket that would carry small satellites, with test rockets set to be dropped from an aircraft in the first quarter of 2018, he said.

Richard Branson and Virgin Galactic CEO George Whitesides.

"There is definitely the demand for all three," Branson said of the competing ventures. "We can take off at 24-hour's notice, put a couple of satellites up and come back again. With ground-based rockets, there's quite a long waiting time. Elon has bigger rockets, so he has advantages there."

Branson declined to comment directly on Donald Trump's June 30 announcement that he'll revive a Cold War-era council that helped shape space policy, or on the US president's suggestion that private companies are set to play "an important role" in the next phase of space technology.

"I think myself and Jeff Bezos and Elon are just getting on with it," he said. "I don't think I've heard of anything majorly exciting that's come out of the administration as far as space is concerned, but maybe they'll surprise us."

Virgin Galactic will also play a role in developing elements of Boom Technologies's planned supersonic plane, Branson said, and will build parts of the XB-1 demonstrator on which the U.S. startup plans to commence work before the end of this year, according to

Branson, a vocal opponent of the UK leaving the European Union, said he's hopeful the country is now headed for a Brexit "kinder" to business following the outcome of May's general election, which left the ruling Conservatives with fewer seats and dependent on the support of a smaller party.

NASA reviews options for Dawn extended mission – SpaceNews

NASA will decide in the next two months whether to keep Dawn in orbit around Ceres or send it to another asteroid. Credit: NASA/JPL-Caltech

WASHINGTON NASA expects to make a decision within the next two months whether to keep the Dawn spacecraft in orbit around the largest body in the main asteroid belt or have it fly past another asteroid.

Dawn completed a one-year extended mission in orbit around Ceres at the end of June, but NASA did not announce whether the spacecrafts mission would be extended again. NASA spokesperson Laurie Cantillo said July 5 that the agencys planetary science division is still reviewing an independent report on the science the mission has achieved at Ceres.

NASAs Planetary Science Division has received and is now reviewing a report from an independent science review panel with regard to Dawns completion of Level 1 science requirements at Ceres, Cantillo told SpaceNews.

That review is required before NASA makes a decision on Dawns future. The spacecraft could remain in orbit around Ceres or use its remaining fuel to travel to another asteroid, she said.

Cantillo said that points of clarification about the report are currently being discussed are part of the overall science review of the mission. Once completed, a decision will be made, most likely in the next 3060 days, she said. Spacecraft operations will continue during the review process.

A project scientist said last month that the mission was considering a flyby. Its an option, Carol Raymond, deputy principal investigator for Dawn at the Jet Propulsion Laboratory, said at a June 13 meeting of NASAs Small Bodies Assessment Group (SBAG). She said then that the mission was in the process of discussing with NASA options for a second extended mission but declined to give additional details about those options.

Project officials proposed an asteroid flyby last year as part of the biannual senior review of planetary science missions seeking extensions. That proposal called for leaving orbit around Ceres in July 2016 and making a slow flyby of the asteroid Adeona in May 2019.

The NASA report that reviewed those extended mission proposals criticized the Dawn proposal for discrepancies, including a lack of specifics and scientific justification, which it blamed on being submitted late in the process. NASA decided instead on a one-year extended mission that remained in orbit around Ceres, in part to ensure that the missions Level 1 science requirements were met.

Dawn, developed as part of NASAs Discovery program of low-cost planetary science missions, launched in 2007. It entered orbit around the main belt asteroid Vesta in July 2011, remaining in orbit there for more than one year. Dawn used its ion propulsion system to leave orbit in September 2012 and travel to Ceres, a body designated by the International Astronomical Union as a dwarf planet, entering orbit in March 2015.

The spacecraft has continued operations despite problems with its reaction wheels, used for attitude control. After suffering the loss of two of its four reaction wheels earlier in the mission, a third wheel malfunctioned in April. The spacecraft went into safe mode briefly, but controllers resumed operations with hydrazine thrusters taking over for the failed wheel.

That failure will eventually lead to the end of the mission when the spacecraft runs out of hydrazine. It does reduce our lifetime because we have to use hydrazine at a faster rate, Raymond said at the SBAG meeting in June.

That lifetime, she said, is dependent on the spacecrafts orbital altitude. Dawn has spiraled out to a higher orbit during its extended mission, which reduces the amount of hydrazine needed for attitude control. The lifetime is now highly dependent on orbital altitude because we need to use the jets to fight the gravity gradient torques, she said.

In its current high orbit, Raymond said that Dawn had sufficient hydrazine, as well as xenon propellant used for the ion engine, to operate at least through the end of 2018. In a lower orbit, like that used by Dawn earlier in the mission for high-resolution mapping of Ceres, the spacecrafts lifetime would likely be limited to weeks.

NASA Is Going To Crash a Satellite Into an AsteroidOn Purpose – Fortune

Photograph by Getty Images/Brand X

On the off chance that giant asteroid ends up on a collision course with Earthand Bruce Willis and Ben Affleck are unavailableNASA is putting together a backup plan

Step one: Crash a satellite into one and see what happens.

The space agency has entered the preliminary design phase for its Double Asteroid Redirection Test (DART). This represents the first trial of what's called the "kinetic impactor technique" of asteroid deflection. Put another way, NASA hopes that by hurling a refrigerator-sized spacecraft at one of the space rocks at a speed roughly nine times that of a bullet, it can knock the asteroid off course and save the Earth.

The plan is to launch the first DART satellite at a binary asteroid called Didymos ("Twins"); the twin asteroids are scheduled to pass by earth in 2022 and 2024. (Neither pass poses any threat, according to NASA.)

By striking one of the two asteroids, scientists will be able to measure the impact of the collision.

Since we dont know that much about their internal structure or composition, we need to perform this experiment on a real asteroid," said Andy Cheng of the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland, the DART investigation co-lead.

So why spend millions to create then crash a satellite in this fashion? NASA says it has found 93 asteroids whose orbits bring them close to earth that are big enough to potentially cause "global effects."

NASA to Test Nuclear Reactor Designed to Power Future Mars Colony – Futurism

In BriefAfter a 50-year break, NASA has returned to the idea of usingnuclear fission to power space missions. However, providing energyfor off-world colonists is just one of myriad questions we willhave to answer before we could hope to become a multi-planetaryspecies. Nuclear NASA

Being able to producepower on alien worlds will define our terraforming and interplanetary colonization experiences how we generate atmospheres, produce lifes prerequisites, and power machines for exploration depend on it. NASA experts estimate that a Mars expeditionwould require roughly 40 kilowatts of power around enough to power eight houses on Earth and they think they may know the best way to generate that energy: nuclear fission.

For the past three years, NASA has been funding Kilopower, a project that aims to develop a compact, low cost, scalable fission power system for science and exploration.

The projects budget is around $15 million, and in September, the agencywill unveil the fruits of their labor a 1.9 meters (6.5 feet) tall generator designed to produce up to 1 kilowatt of electric power during testing at the Nevada National Security Site.

Although other alternatives for generating power have been put forward, none are as viable as fission. Solar energy, for instance, would require that astronauts stick to regions that receive an adequate amount of sunlight. If you want to land anywhere, surface fission power is a key strategy for that,Michelle Rucker, an engineer at NASAs Johnson Space Center, told Space.com.

Project Kilopower marks something of a fission resurgence for NASA after a hiatus of more than 50 years. The last time the agency operated a fission reactor was in 1965, when they launched the Systems for Nuclear Auxiliary Power (SNAP) project. That project resulted in radioisotope thermoelectric generators (RTGs) that are still used to power spacecraft today, as well as the nuclear-powered spacecraftSNAP 10A, which stopped working 43 days after it was launched into space due to an electrical component failure.

Individuals such as Stephen Hawking have issued warnings that Earth cant survive our habitation for much longer, so finding an alternative home for humanity is becoming critical.The question of how to provide power off-world is one of the biggest ones we face as we consider the Red Planet as our future home.

Other aspects of Mars colonization are already falling into place. Elon Musks SpaceX is driving the transportation elementof the cosmic migration forward, developing detailed plans and working on ever-larger spaceships that we could use to get to our planetary neighbor.

Several solutions have been proposed to help us generate a habitable atmosphere. TheDefense Advanced Research Projects Agency (DARPA)is considering using bacteria that would form algae to warm and thicken the atmosphere, while NASA detailed at the Planetary Science Vision 2050 Workshop earlier this year how they could build an Earth-like magnetic field around the planet.

If we ever successfully move to another planet, these questions and hundreds more, such ashow diseases will respond to spaceand how reproduction will work,will have to be answered. Estimates concerning how long this will take vary, with some saying decades and others saying centuries. At any rate, let us hope it is sooner rather than later if Hawkings prediction proves to be accurate.

NASA marks 20 years of continuous Mars exploration – Spaceflight Now

NASAs Mars Pathfinder probe dropped to the surface of Mars for an airbag-cushioned landing 20 years ago Tuesday, bouncing 15 times across an ancient flood plain before deploying a mobile robot to usher in two decades of uninterrupted Martian exploration.

The Independence Day landing in 1997 was the first touchdown of a robot on Mars since NASAs Viking landers arrived in 1976, and the U.S. space agency has since maintained a continuous robotic presence at the red planet, dispatching additional landers, rovers and orbiters to sample rocks, monitor Martian weather, and glimpse into the worlds warmer, wetter past.

Ithink Mars holds a special place in everyones hearts because it looks a lot like the Earth it looks like a place we could live, said Mike Watkins, director of NASAs Jet Propulsion Laboratory, where engineers developed, built and operated Mars Pathfinder.

Watkins said Pathfinders landing on Mars helped lead NASA to answer fundamental questions about Earths neighbor: What was its history? How did Mars get the way it is? Was it once habitable?

Follow-on missions have sent rovers driving across dried-up lake and river beds, to deposits left by ancient hot springs, and orbiters that found signs of intermittent water still present on the desert planet and helped unravel how Mars became so cold and inhospitable.

I believe that Pathfinder, in particular, helped us understand a new way of exploring planets, Watkins said in a panel discussion televised on NASA TV. You could argue that Viking, as the first planetary lander, sort of pioneered in situ science, but that was kind of a one-off mission. I think Pathfinder showed us not only that mobility can be useful, but the notion of an ongoing interactive exploration of a planet, a voyage of continuous discovery.

Conceived in late 1993 as NASA faced a severe budget crunch in the wake of several high-profile robotic mission mishaps, Mars Pathfinder had to fit within stringent cost and schedule limits.

NASA Headquarters in Washington, at the behest of then-administrator Dan Goldin, gave engineers at JPL three years and $150 million to ready the lander for launch in December 1996. Goldin said NASA could no longer afford multibillion-dollar missions to explore the solar system in an era of nearly-flat budgets.

The agency had to revamp how it conducted interplanetary missions after the Viking Mars landings and the Voyager probes first forays into the outer solar system, Goldin said recently, because money is not the magic ingredient.

Goldin infused his mantra of faster, better, cheaper across NASAs programs, leading to the launch of fleets of smaller, less costly spacecraft to study the cosmos and visit unexplored destinations, from new regions on the Martian surface, to Mercury, Pluto, asteroids and comets.

Mars Pathfinder got its start months after controllers lost contact with NASAs $813 million Mars Observer orbiter days before it was to arrive at the red planet. But NASAs next Mars mission, despite vastly more ambitious objectives, ended up costing about one-third the expenditure that went into Mars Observer.

We had to do something bold, Goldin said during a celebration of Pathfinders 20th anniversary. It just couldnt be another orbiter It had to be really hard. When you compare what it cost for Viking, that was billions, and now were a factor of 20 (less) on cost and a factor of three (less) on schedule, with technology that they didnt have time to develop in advance.

While Pathfinders team had to work within tight financial and time boxes, managers said they had freedom to innovate. In real terms, that usually meant building, breaking, then fixing a part that needed to fly on the mission.

When something went wrong and there was a problem, I could being together a handful of people, and in a matter of minutes, to hours or maybe a few days, we could undertsand the problem and we could put a solution in place and wed go execute it, said Brian Muirhead, Mars Pathfinders flight system manager at JPL. Sometimes, in our big projects today, it could take weeks to months to make those kinds of changes.

One example was a cable that engineers designed to extend below the lander during final descent to measure its altitude. That didnt work, so designers opted for a radar to bounce signals off the Martian surface for altitude data, but that solution also proved complicated as a prototype lander swung beneath a parachute during drop testing in Earths atmosphere.

The landers inflatable cushion was also tricky, but engineers needed the airbags to keep the spacecrafts mass down, exchanging air for heavier rocket fuel to bring the robot to a rest on Mars. The Viking landers relied on retrorockets to brake for touchdown, but the airbags, in principle, were more resilient.

Mission engineers procured time on a supercomputer at Sandia National Laboratories to model how the airbags would respond to different terrains and conditions on Mars. Muirhead said the airbag tests brought the computer, one of the most powerful in existence at the time, to its knees.

There were certain parts of it we came to realize you really couldnt treat very well with a computer simulation, airbags being, by far and away, the foremost example, said Sam Thurman, Mars Pathfinders entry, descent and landing system engineer at JPL.

NASA sent a full-scale model of the airbags, made of a high-strength fiber called Vectran, to the Plum Brook Station in Ohio for drop tests against an inclined, rocky floor meant to mimic the Martian surface.

Mission managers were finally comfortable with the airbag design in early 1996, deeming the system qualified for the trip to Mars eight months before blastoff.

Mars Pathfinder departed Earth on Dec. 4, 1996, riding a Boeing Delta 2 rocket from Cape Canaveral on the first leg of its seven-month voyage.

Unlike the Viking landers, which dropped to Mars from orbiting motherships, Pathfinder made a direct descent, slicing through the atmosphere at higher speeds than the Vikings experienced.

A heat-resistant shield protected the lander during the first part of entry, then a supersonic parachute deployed, braking rockets fired and the airbags inflated before the shepherding craft cut the landers Kevlar bridle.

Shortly before 10 a.m. PDT (1 p.m. EDT; 1700 GMT) on July 4, 1997, the lander hit the ground at about 31 mph (14 meters per second), and rebounded several stories high, bouncing at least 15 times before coming to a stop more than a half-mile (1 kilometer) from its original landing point in Ares Vallis, a rocky plain in Marss northern hemisphere.

The airbags deflated automatically, opening Pathfinders flower-like petals to make way for the exit of the Sojourner rover, a six-wheeled vehicle that was not originally part of the Pathfinder mission.

NASA added Sojourner after scouring the agency for money to fund it, and its cost, along with the price of the Delta 2 booster and a three-month operations budget, pushed Pathfinders final cost to $264 million.

The Pathfinder lander soon transmitted its first signals to anxious engineers on Earth, and the first images were beamed back to the ground a few hours later.

The very first thing we wanted to do is to get those images down to see what the landing site looked like, and the rover on the petal, said Jennifer Trosper, Pathfinders flight director.

I remember getting those images down, and we were printing them out on printers, she said, in contrast to todays smartphone and social media age.

The Sojourner rover, named for American civil rights pioneer Sojourner Truth, drove down a ramp to start traversing the landing zone the day after arriving on Mars. Staying in touch with mission control via a wireless modem link with the stationary landing platform, the solar-powered rover about the size of a microwave oven inspected the rock-strewn region nearby, logging more than 300 feet (100 meters) on its odometer.

Designed to last between one week and one month, Sojourner relayed data for nearly three months until the Pathfinder landing station stopped communicating with Earth on Sept. 27. The ground team suspected the spacecrafts battery was depleted and its internal temperature dropped below a safe level, according to a mission fact sheet posted on a NASA website.

The end of Pathfinders mission came about two weeks after NASAs Mars Global Surveyor spacecraft slid into orbit at the planet.

The Sojourner rovers chassis was a forerunner to bigger vehicles, first the identical Spirit and Opportunity rovers that landed in 2004, and then the Curiosity mission that arrived in 2012.

The Opportunity and Curiosity rovers are still moving across the red planet today, and another rover based on Curiositys frame will launch to Mars in July 2020.

Look at the legacies that that little rover have led to, to Spirit, Opportunity, Curiosity, and then Mars 2020, said Charles Elachi, JPLs director from 2001 through 2016. Thats a kind of small but visionary technology investment that NASA and Dan (Goldin) were very well known for, which led us to do the great things that we do now.

But the last 20 years of NASA Mars missions have not been without blemishes.

NASA lost two spacecraft as they arrived at Mars in late 1999, both of which followed in the footsteps of Pathfinder, incorporating Goldins faster, better, cheaper philosophy.

The Mars Climate Orbiter burned up in the Martian atmosphere as it tried to enter orbit in September 1999, an error caused by the mismatch of English units and metric units used by the crafts navigation and operations teams. Less than three months later, the Mars Polar Lander crashed on the red planet, likely due to a premature engine shutdown.

Investigators said a contributing cause of the mishaps was their tight budgets, concluding the projects were under-funded by at least 30 percent.

NASA gave more money to subsequent Mars missions and added additional engineering reviews to ensure their readiness for launch.

Mars scientists have had at least one operating mission at Mars every day since Pathfinders Independence Day descent 20 years ago. NASAs Mars Odyssey joined Mars Global Surveyor in 2001, and the Spirit and Opportunity rovers blasted off in mid-2003, along with the European Space Agencys first interplanetary mission, Mars Express.

Odyssey, Opportunity and Mars Express are still returning scientific data all years beyond their intended lifetimes while Mars Global Surveyor stopped transmitting in 2006 and engineers last heard from the Spirit rover in 2010.

The Mars Reconnaissance Orbiter, carrying a high-resolution mapping camera, launched in August 2005 and arrived at Mars in March 2006. NASA is still getting data from MRO, which returns dazzling sharp-eyed views of Martian terrain.

NASAs Phoenix lander touched down on the northern polar plains of Mars in May 2008, succumbing to the extreme Martian winter in November 2008 as expected.

The Curiosity rover has explored Gale Crater, an impact basin rife with geologic features like dunes, buttes and a three-mile-tall mountain, since August 2012. NASAs MAVEN orbiter has been sampling the upper atmosphere of Mars since 2014, and India flew its first planetary mission into Martian orbit the same year.

The newest arrival is ESAs ExoMars Trace Gas Orbiter, which aims to seek the source of methane in the Martian atmosphere, a potential indicator of ongoing biological or geological activity.

Many of Pathfinders engineers have worked on all of JPLs Mars rovers.

One of the great legacies of Pathfinder and the Mars program is it allowed us to do engineering the way engineering is done, which is to have the same people do a mission, learn what they did right or wrong, and then do another one, and then do another one, Watkins said.

The series of missions, launching at cadences as short as every two years when the planets are properly aligned, have helped NASA build up a knowledge base they we really havent had for any other planet, Watkins said.

NASA’s Juno spacecraft is about to peer into the depths of Jupiter’s Great Red Spot – Popular Science

Humankind has been ogling Jupiters Great Red Spot through our telescopes for more than 300 years. The Voyager and Galileo missions brought us closer to understanding where this 10,000-mile-wide storm comes from, but its still swirling with mysteries. Well, it better get ready for its close-up: Next week, NASAs Juno spacecraft will come closer to the furious tempest than any spacecraft ever has before, hopefully solving some of those mysteries in the process.

On July 10, Juno will fly directly over the Great Red Spot, passing about 5,600 miles above the glaring eye. During the flyby, all eight of the spacecrafts instruments will be turned on to gather data, including its camera.

Scott Bolton, who heads up the Juno mission, says the team is looking forward to exploring a variety of questions when the spacecraft gets there. The most basic one is: whats it look like when you get really close? says Bolton. Thats sort of a fundamental question, and there are scientific questions of course that are tied to that.

Although Bolton cant say for sure what Juno will find when it gets there, hes hoping the cameras send back stunning imageswhich isnt too much to hope for, since the spacecraft is already sending back remarkable shots of other parts of the gas giant.

The data may reveal new details about how this massive storm, with winds whipping as fast as 425 miles per hour, and Jupiters atmosphere in general, work. Instruments on the probe might help to explain where the storm gets its red coloration, and could even peer below the surface of the storm for the first time ever.

It sees through the cloud tops, and we can investigate how deep the [storms] roots are, says Bolton. Do we see a signature at all underneath the cloud tops, or is it just a shallow feature? That helps us understand maybe how its made, and why its lasted this long.

Although many scientists think the storms roots must go very deep into Jupiters atmosphere, Bolton says Junos observations could potentially throw out that hypothesis. Until now, weve never had any kind of instrument that could see below the top layer, the veneer, of Jupiter.

NASA Is Going Nuclear for Mars – Houston Press

NASA wants to put nuclear reactors on Mars.

Image from NASA

NASA is moving forward with plans to land on Mars by the 2030s, so the agency is also working out how to keep people alive once they actually get there. And thus, for the first time since the 1960s, NASA is zeroing in on nuclear fission.

One idea that is gaining some traction is a set of small nuclear reactors to provide power on the red planet. NASA is preparing to test out the idea. In September, NASA researchers are slated to head out to the Nevada desert, where they will start testing a technology that may lead to astronauts landing on Mars equipped with their own small nuclear reactors someday.

The project, Kilopower, has been in development since 2014, and will see the building of small nuclear fission reactors. The plan is that uranium atoms will be split in these relatively tiny reactors, giving off extreme heat that can then be converted into electricity. The first run will be at the Nevada National Security Site near Las Vegas. Testing is due to start in September and end in January 2018.

The test reactor, which is a little more than six feet tall, will produce up to one kilowatt of electric power. NASA's prediction is that a Mars base would require a supply of just 40 kilowatts equivalent to the power needs of eight houses on Earth.

This is the first time since 1965 that NASA has gotten into fission reactors. The first venture was under NASA's Systems for Nuclear Auxiliary program (a.k.a. SNAP), which saw the development of two types of nuclear reactors. The first kind,radioisotope thermoelectric generators, or RTGs, use heat released from the natural decay of a radioactive substance, like plutonium. This type of generator has been used to power various space probes, including the Curiosity rover currently on Mars, over the years.

But NASA didn't stop there. The SNAP program also gave rise to the development of an atom-splitting nuclear fission reactor, SNAP 10A. It was launched in 1965, the first and only nuclear power plant to be sent into space, where it operated for 43 days before failing. (The craft it was on is still in orbit around Earth now.) That was the end of the nuclear fission program from then until now, at least as far as NASA is concerned.

The Russians had better luck with fission reactors. The Soviet space program developed more than 30 Radar Ocean Reconnaissance Satellites between 1967 and 1988, followed by theThermionic Experiment with Conversion in Active Zone (TOPAZ).

So the Russians have been way ahead of us on fission reactors, but not because NASA hasn't been interested. Over the past 50 years, the space agency has backed a number of nuclear power technology efforts, but the programs never got very far because of a mix of political, technical and financial problems.

However, NASA is working to get back on board with nuclear fission. The $15 million project to test the new nuclear fission reactor will mark the first time that NASA has powered up such a reactor that could be used in space since the SNAP program back in the 1960s.

The first tests will be aimed at proving the design for the reactor works. Once all of that is worked out, NASA should be ready to start building full-scale reactors that could actually be used on Mars.That's going to be crucial because once people get to Mars, they'll need a power source to produce everything from air to water to fuel. The plan is currently to send four or five fission reactors on the trip, launched cold and activated only once they have landed on the planet.

Problems aside, NASA moves toward SLS structural testing at Marshall – SpaceFlight Insider

July 5th, 2017

NASA and Boeing have cleared the component, shown here, for use as the bottom of the dome of an SLS liquid oxygen tank structural test article. After the dome is welded to the rest of the test article in the Vertical Assembly Center, right, it will undergo inspection and processing before being shipped from the Michoud Assembly Facility in New Orleans to NASAs Marshall Space Flight Center in Huntsville, Alabama, for structural testing.

Moving beyond site selectioncontroversy and production problems that caused headlines in May,NASA is working to complete a Space Launch System (SLS) structural test article at the Space Agencys Michoud Assembly Facility (MAF) in Louisiana.

Early in May, workers discovered that the forward liquid oxygen tank dome had been damaged during welding, raising concerns the item would be useless for structural tests planned at Marshall Space Flight Center in Alabama. However, engineers from NASA and prime contractor Boeing have now cleared the dome for use and completed repairs to the MAFsspecialized friction stir welding assembly.

Much of the hardware necessary for the structural tests on the SLS core stage has already been completed. The engine section, which will mount fourRS-25 engines, was shipped to Marshall in April. The liquid hydrogen tank welding was completed in September of last year, and the intertank section was recently completed. Among the major test items, only the liquid oxygen tank remains unfinished. Meanwhile, Boeing has begunwelding the first flight-intended liquid hydrogen tank.

Engineers assembled the structure of the intertank that will be flown on the first Space Launch System integrated flight with Orion. The intertank, one of five parts of the 212-foot core stage being built and assembled at NASAs Michoud Assembly Facility in New Orleans, is on its way to undergo the application of thermal protection systems. The intertank is the only major structural part of the core stage that is not welded. It is made of eight large panels which are connected with 7,500 bolts. The 22-foot-tall structure carries most of the massive launch load produced by the solid rocket boosters that separate from the core stage about two minutes after launch.

The Space Launch System intertank, shown here moving down the factory floor, finished structural assembly at NASAs Michoud Assembly Facility in New Orleans. Technicians moved it to an area where it will be coated with a thermal protection system. The yellow object (left back) is the engine section of the core stage, which also completed structural assembly and is being outfitted with propulsion system hardware that will feed fuel to the four RS-25 engines on the first SLS mission.

The completed test articles will be qualified at a Marshall-basedtest stand that NASAsInspector General harshly criticizedin a May report. The IG found that NASA didnot adequately consider alternate locations, such as Stennis Space Center in Mississippi, where NASA already hosts rocket engine testing. It noted that the journey by barge from Michoud to Marshall required two weeks of travel for each test component on a bargethat could only carry one piece at a time requiring six weeks total of travel and a total cost of over $1 million.

The entire test article could be shipped to Stennis within a week ata total cost of around $200,000.

The IG also criticized the space agency for not considering life cycle costs and ordering construction based on incomplete designs and specifications. The reportrecommended that stricter procedures govern NASAs testing construction in the future, but noted that it was too late to move the test standsas NASA was moving ahead quickly with its test schedule.

LEFT IMAGE: NASA cleared the dome, shown here being removed from the infeeder tool, for use as intended as the bottom dome of the liquid oxygen tank structural test article being welded in the Vertical Assembly Center, right. The dome sustained minor damage during operations May 3, 2017. The investigation team is currently wrapping up their investigation of the mishap and will prepare recommendations to the SLS program. RIGHT IMAGE: More than 500,000 U.S. gallons of fuel will flow from the liquid hydrogen tank to the four RS-25 engines that power NASAs Space Launch System rocket. During a flight, and even during testing, a tanks insides must be clean to ensure contaminants do not find their way into complex propulsion and engine systems. Technicians recently lifted the liquid hydrogen tank structural qualification test article into a cleaning cell at NASAs Michoud Assembly Facility in New Orleans where its insides will be thoroughly cleaned, coated, and dried to certify the process for the following flight article.

The liquid hydrogen tank test article is currently waiting for shipment to Marshall, and the liquid oxygen tank lacks only the aft dome before welding on it is completed. The intertank section, which is bolted together, rather than welded, is also waiting for shipment to Marshall.

Once all the components arrive at the test stands in Alabama, they will be subjected to structural tests to certify the SLS design for flight by simulating the stresses the heavy-lift rocket will experience during its launch and ascent.

Nanotechnology to protect astronauts from harmful radiation, and … – ABC Online

Updated July 05, 2017 11:57:18

Imagine a window that could instantly turn into mirror the possibility is real, thanks to a breakthrough in nanotechnology by researchers at the Australian National University (ANU).

They have developed a material that promises to protect astronauts from harmful radiation, as well as practical uses closer to home.

ANU researchers have dubbed their invention a "smart mirror", and all that is needed for it to change is an adjustment to its temperature.

"Our smart mirror consists of lots of dielectric nanoparticles which are carefully designed and arranged within a single layer," ANU lead researcher Dr Mohsen Rahmani said.

The layer of nanoparticles are spread so thin that they are just 0.00005 of a millimetre apart.

"Today's technology, all optical silicates consist of the elements that work statically," Dr Rahmani said.

"Which means they either transmit the light or reflect the light, or something in between."

Until now, optical silicates have only achieved one function.

But with a switch in heat, this new one promises to transform to either absorb, reflect or emit light and radiation.

"By our technology, for the first time you can have a single element which can have all those functions at the same time, and you can control the light passing through or reflects," Dr Rahmani said.

Dr Rahmani said the film was thin enough to coat a pin head hundreds of times, and could be applied to any surface like a spacesuit.

"By adjusting the temperature of that thin layer, we are able to control the optical properties of those nanoparticles," he said.

"So that the entire surface can either transmit or reflect the incoming light on demand."

One of the major problems involved with prolonged space travel is exposure to cosmic radiation.

Currently thick filter panels are needed to protect both space craft and astronauts.

"As we know, the temperature in space varies a lot," Dr Rahmani said.

"Just imagine we can have a smart mirror which can reflect different frequencies at different temperature.

"It can give a great platform to protect the devices or astronauts in different environments in the space."

Sending people into space has seen the creation of a number of innovations and inventions now used in daily life memory foam, quick-dry anti-rust paint, water filters, and some bulletproof fabrics all came from the space race.

And just like those innovations initially designed for space travel, this one also has useful applications on Earth.

Just like a car's back window has wires running through it to defog it with a change in heat, a similar system has been proposed to control the temperature in the new film, switching clear glass to a mirror or an illuminated panel.

"The principle is quite extendable to other frequencies as well," co-researcher and associate professor Andrey Miroshnichenko said.

"Including visible, which opens [a] whole range of new types of application, including architectural ones.

"Where for example, your window becomes a mirror."

With mirrors switching to light panels, the ANU team said the technology also promises to save energy.

Using Nanotechnology for Space Elevators, Direct Cell Delivery – Edgy Labs (blog)

The infinitely small nanotech world helps science take great leaps forward, from therapeutic nanosystems treating the body to space elevators.

In recent years, advances in nanosciences have been so numerous and varied that they affect the progression of many different scientific fields.

Whether in physics, chemistry, biology, medicine or space, nanotechnologies help many scientific disciplines to overcome limitations. Harnessing the power of the very small enables the development of novel solutions and the revisiting of old concepts that until now remained inaccessible.

Here are two potential futuristic concepts, for space and medical applications, that were discussed by a panel of researchers and scientists at Future Con, held at the Walter E. Washington Convention Centerin Washington D.C. from June 16th to the 18th.

For over a century, space elevators have been heralded as a potential revolutionary space transportation system. In 1895, Constantin Tsiolkovsky, a Russian scientist proposed a celestial castle that would float in Earths geosynchronous orbit (GEO), attached to a high tower on the ground via cables.

Naturally, speculative writers have used variations of space elevators as plot devices. In his 1979 novel The Fountains of Paradise, Arthur C. Clarke describes the construction of the first space elevator in the 22nd century.

Imagine an elevator that goes a couple hundred miles up with nothing but wires to lift it from a ground station to one floating in space. The project sounds unfathomable, but thanks to nanotechnology, it is now scientifically viable.

Lourdes Salamanca-Riba, Professor at A. James Clark School of Engineering at the University of Maryland thinks that if cables were to be made from steel, the system would collapse under its own weight. Salamanca-Riba, who spoke at Future Con, proposed instead carbon nanotubes.

One-atom-thick carbon nanotubes (CNTs) are ultralight but extremely resistant and strong, which makes them perfect to make cables that carry the space elevator to a space base, 10,000 miles up.

With the longest synthesized CNT ever is 50 centimeters long, theres a long way to go until carbon nanotubes that can reach beyond Earths atmosphere are scalable.

Another panelist at the Future Con was Jordan Green, an associate professor at the Johns Hopkins University School of Medicine in Maryland, who made the observation that, in order to replicate, some viruses integrate their genes into the genome of a cell.

Green then discussed special nanosystems as a means to send genetic information to infected cells to cure them.

For some cancers and hemophilia, such systems could be used to genetically modify infected cell. By restoring and/or repairing genetic inadequacies or errors, affected cells can heal and regain their normal function withoutbeing destroyed.

For cancer, targeted gene therapycould encourage cancerous cells to halt malignant spread and even self-destruct.

Global Nano Chemotherapy Market & Clinical Trials Outlook 2022 – PR Newswire (press release)

LONDON, July 5, 2017 /PRNewswire/ -- "Global Nano Chemotherapy Market & Clinical Trials Outlook 2022" report highlights the current development in the in the field of nano chemotherapy. Report gives comprehensive insight on various clinical and non-clinical parameters associated with the expansion of global nano chemotherapeutics market. The clinical and pricing insight on chemotherapeutics nanoformulations of approved drugs helps to understand the current market scenario of the nano chemotherapeutics.

Download the full report: https://www.reportbuyer.com/product/4884894/

Nano chemotherapy is emerging as an important anti-cancer modality by supplementing the traditional chemotherapy. The main aim of nano chemotherapeutics is to improve the therapeutic efficacy of currently available chemotherapeutic agents by combining it with a nano scale delivery component. The majority of the cancer nanodrugs in the market are liposomes and polymer based nanoformulations which lower the toxicity and enhance the delivery of chemotherapeutics through the passive targeting. It is based on enhanced penetration and retention effect to reduce the lymphatic drainage in tumor tissue.

Conventional chemotherapeutic agents are distributed non-specifically in body where they affect both cancerous and normal cells and thereby it limit the dose availability with in the tumor and also results in suboptimal treatment due to excessive toxicities. To overcome the limitations of chemotherapy treatment, many more therapies has also been emerged.

The use of nanoparticles by both passive and active targeting strategies can enhance the intracellular concentration of drugs in cancer cells while avoiding the toxicity in normal cells. When the nanoparticles bind to a specific receptors and then enter the cell, usually enveloped by endosomes through receptor mediated endocytosis and thereby bypassing the recognition of P glycoprotein.

Nanomedicine has already met with success in oncology domain with various product commercially available in the market. By releasing the efficacy of nanomedicine in oncology, it increases the interest of the market players to commercialize the products in the field of nanotherapeutics and helps to increase the global market. The future of nanotherapeutics is bright and especially for the reversible cross linked nano carriers which are decorated with the cancer targeting ligands and it promote the endocytic uptake in tumor cells. The approach has the potential to overcome the drug resistance which is often with conventional chemotherapies.

For the next generation cancer nanotherapeutics, the complexity is higher which are under clinical development in terms of hybrid structures, surface physiochemical characteristics and mechanisms of delivery and action. There have been rapid advances in the nano therapeutic field in the past decade. Many of the nano carriers have been developed from which some have the great therapeutic potential. However, there remain many challenges in translating the nanoparticle drugs into the clinics. Download the full report: https://www.reportbuyer.com/product/4884894/

Metallic nanomolecules could help treat fatal lung disease in the future, notes research – EPM Magazine

New research from Imperial College London, that has recently been published online, examined a novel type of nanoparticle called metal organic frameworks (MOF) as drug carriers for the treatment of pulmonary arterial hypertension (PAH).

Published in Pulmonary Circulation, the research describes the first steps in the development of nanoparticles that can deliver drugs directly to the lungs. The MOFs, created in the laboratory by the researchers, are composed of iron and can expand to create pores within which drugs used to treat PAH can be stored and released where needed.

The hope is that using this approach will ultimately allow for high concentrations of drugs we already have to be delivered to only the vessels in the lung, and reduce side effects, explained Professor Jane Mitchell, from the National Heart and Lung Institute at Imperial in a news release. For patients with PAH, it could mean we are able to turn it from a fatal condition, to a chronic manageable one.

When testing the MOFs, the team from Imperial found that the structures reduced inflammation and were not toxic to human lung cells and blood vessels in laboratory conditions. Further testing in rats, showed the MOFs were safe in the animal model over a two-week period with few side-effects a slight build-up of iron was seen in the liver.

One of the biggest limitations in nanomedicine is toxicity, some of the best nanomedicine structures do not make it past the initial stages of development as they kill cells, continued Mitchell. We made these prototype MOFs, and have shown they were not toxic to a whole range of human lung cells.

The aim is to develop the metallic structures as a drug delivery method where the framework can hold onto the drug and release it under specific conditions, such as a change in pH, temperature or using magnets external to the body to draw the MOFs to the target area. Next steps for this research is to discover the ideal way to get the tiny structures loaded with drugs and delivered to the lungs effectively.

In this study we have proved the principle that this type of carrier has the potential to be loaded with a drug and targeted to the lung, Mitchell concluded. This is fundamental research and while this particular MOF might not be the one that makes it to a drug to treat PAH, our work opens up the idea that this disease should be considered with an increased research effort for targeted drug delivery.

What Moore’s Law has to teach us about WanaCrypt0r – SC Magazine UK

Kirsten Bay, president and CEO, Cyber adAPT

WannaCrypt0r the malware that held data to ransom on a global scale was a powerful illustration of what happens when cyber-security loopholes are not effectively closed. Exploiting a weakness in Microsoft's Windows operating system, the cryptoworm spread between PCs like wildfire, encrypting data and demanding Bitcoin payment in exchange for its return.

It is fair to say the attack took most cyber-security professionals by surprise. But was it really so unfathomable and, more importantly, how can we ensure such attacks are not repeated?

The answer to these questions lies in a theory proposed by Intel co-founder, Gordon Moore, in the 1960s: the processing power of computers doubles every two years.

Having dominated computing for the last 52 years, Moore's Law is now looking set to run out of steam, and it is the reason behind this has much to teach us about cyber-security now, and in the future.

Keeping up with the hackers

According to Europol chief Rob Wainwright, the best way to stop WanaCrypt0r infecting PCs and corporate networks is simple: installing a Microsoft patch on all machines.

Yet as the attack has shown, keeping security systems up to date is challenging. Microsoft, after all, had already released the MS17-010 patch before the ransomware hit, but failure of individual users and businesses to update promptly meant 150 countries were still affected.

The hard truth is: security breaches are not just increasing; they are inevitable especially in large organisations where networks support multiple devices that all run different software. And considering the scale of the biggest organisations affected the UK's National Health Service and FedEx it is easy to see how PCs running outdated systems, like Windows 7, were overlooked.

The key conclusion we can draw from this latest breach is that our tendency to focus on protecting specific networks or devices is a serious error. And this is where Moore's Law comes in

From chip-power to the cloud

When Moore first made his observation, technology was different computing power was determined by how many transistors a dense integrated circuit, or chip, could hold. After noting that the transistor to chip ratio was doubling every two years (a revised estimate made in 1975), he predicted that processing capability would grow at the same rate, and so Moore's Law was born.

Although the theory has been verified by more than half a century of multiplying transistors and shrinking chips, empirical support for it is dwindling. Indeed, in 2015, Moore himself said he saw the law dying in the next decade or so.

The reason for this is that computing capability is no longer tied to hardware. The advent of cloud computing means software, data and extra processing capacity can now be accessed over the internet without increasing the number of transistors in a device.

Thus, when we apply the same argument to cyber-security the problem is clear: current measures are trying to protect limited networks and specific devices, but networks are now edgeless and used by myriad devices. In other words, the idea of patching every single device linked to the network is unrealistic and we are trying to keep a gate closed that is simply too wide.

Outside in: building internal defences

To outpace the hackers, we must learn from the failings of Moore's Law and take a lateral security perspective that extends beyond individual devices.

CISOs need to adopt a detection-led approach that focuses on preventing attacks after hackers have breached networks by monitoring for and removing suspicious users. In doing so, they can ensure their cyber-security measures are fit for the 21st century, rather than embarking on an endless mission to update every device each time a threat is identified. And with such defences in place, security professionals could stop the next ransomware attack from spreading so quickly, or at all.

The demise of Moore's law teaches us that modern security cannot afford to view networks as silos. With the cloud constantly creating new connections, there are no more perimeters to protect, which means keeping systems safe requires defences that can identify hackers after they have made their way in.

By deploying a detection-led method, CISOs can use the lessons of the past to secure networks at all times, and ensure they are positioned tothwartthe next WanaCrypt0r-style-attack in its early stages.

Researchers use virtual reality to unpack causes of common diseases – Medical Xpress

July 5, 2017 Credit: University of Oxford

Researchers from the University of Oxford are using a unique blend of virtual reality and innovative genetic techniques to understand the causes of diseases such as diabetes and anaemia.

The team, working in collaboration with physicists from Universita' di Napoli and software developers and artists at Goldsmiths, University of London, are using the state-of-the-art technology to investigate the 3-D structure of DNA. The way in which DNA is arranged in 3-D space has huge consequences for human health and disease. Subtle changes in DNA folding impact on whether genes can be switched on or off at particular times dictating what a cell can do. It is this process that the team are trying to get to the bottom of in the hunt for the causes of disease, and potential new treatments.

The scientists are presenting their research at the Royal Society's annual Summer Science Exhibition.

Prof Jim Hughes, Associate Professor of Genome Biology, University of Oxford, said: "It's becoming increasingly apparent that the way that a cell fits two metres of DNA into a structure more than ten times smaller than a human hair, is more than just a random process. We are dissecting this intricate folding to understand which parts of our immense genome are interacting at any one time, helping us understand whether changes in this process can cause disease."

The video will load shortly

CSynth the software on show at the Royal Society's Summer Science Exhibition is designed to provide an engaging way to explore and understand the complex structure of the genome in 3-D, by integrating data from genome sequencing, computer modelling and high powered microscopy. Scientists are now hoping to use virtual reality to visualise the huge amounts of data they can generate in the laboratory.

Speaking about the software, Stephen Taylor, Head of the Computational Biology Research Group at the MRC Weatherall Institute of Molecular Medicine, University of Oxford, said: "With advances in genetic techniques, we can now harness more information than ever before from biological data provided by patients and volunteers. With the CSynth software we can integrate data from different experiments into something more tangible to help researchers understand how DNA folds. In addition, using the Virtual Reality mode in CSynth is helping us visualise these complex 3-D structures in a more intuitive way."

Prof William Latham from the Department of Computing, Goldsmiths, University of London, said: "I'm fascinated by the way we can use art to better understand and envision scientific concepts. In CSynth we've created something that not only accelerates research progress, but also allows the public to share in unravelling some of the mesmerising and intricate structures inside our body."

Prof Frederic Fol Leymarie from Goldsmiths, said: "By combining maths and physics together with computer games technologies, we can program realistic molecular interactions, and immerse people in the dynamic world of DNA. CSynth takes you on a close encounter with the very fabric of life."

Asthma drug shows promise in treating obesity and diabetes – University of Michigan Health System News (press release)

ANN ARBOR, Mich. -- After 12 weeks of taking an anti-inflammatory asthma drug, obese patients with type 2 diabetes showed a clinically significant drop in blood glucose.

The drug amlexanox, prescribed in Japan to treat asthma, appeared to free the metabolic system to burn more energy. A subset of patients had improved fatty liver disease and insulin sensitivity, a response seen among those who started the clinical trial with higher levels of inflammation in their fat tissue than others.

While the discovery at Michigan Medicine and the University of California at San Diego is not ready for the clinic, it reveals an inflammatory link between obesity and type 2 diabetes.

Inflammation is the bodys natural response to injury and illness, but chronic inflammation caused by obesity is believed to promote insulin resistance, a main feature of diabetes.

We are beginning to understand the role this form of internal inflammation plays in the development of chronic diseases like diabetes, says lead study author Elif Oral, M.D., director of the MEND Obesity and Metabolic Disorder Program at Michigan Medicine. Ultimately we may be able to personalize therapy based on the degree of inflammation present at baseline which is a new concept.

Oral is an endocrinologist and translational scientist at Michigan Medicine, the University of Michigans academic medical center where the clinical trial was conducted and analyzed.

Tissue analysis was led by study author Alan R. Saltiel, Ph.D., at U-C San Diego, along with scientists at the Salk Institute for Biological Sciences.

In the Cell Metabolism study, researchers identified a molecular signature in obese patients with type 2 diabetes who responded to the drug amlexanox.

When we looked at the drug-treated group we saw a bimodal distribution, that is, there were some responders and some nonresponders. We didnt understand why, so we did a molecular analysis from biopsies of fat cells we took from patients at the beginning and end of the study, says Saltiel, director of the Institute for Diabetes and Metabolic Health at U-C San Diego

In the responder group, the level of inflammation in fat was higher than in the nonresponder group at the beginning of the study, indicating that there is something about inflammation that predisposes a person to respond. And, what was really amazing was that there were more than 1,100 gene changes that occurred exclusively in the responders.

The glucose-lowering effects of amlexanox were first discovered in mice during research at the University of Michigan where Saltiel served as director of the Life Sciences Institute at the U-M.

Promising results

Amlexanox is an inhibitor of two enzymes, IKK and TBK1. In previous studies, Saltiel and U-M researchers discovered that these two enzymes are induced in obese mice, causing a drop in energy expenditure or reduction in calories burned.

This prompted them to look for inhibitors of these enzymes by screening a library of 150,000 chemicals. They found amlexanox. Giving obese mice the inhibitor caused them to lose weight, while their sensitivity to insulin increased, improving their diabetes and fatty liver disease.

The human trial revealed that gene changes that occurred in the mouse model also happened in the human responder group. Blood sugar in the clinical trial patients went down as genes involved in the expenditure of energy changed.

The proof of concept trial began with an unblinded safety trial of six patients. It was followed by a controlled trial of 42 obese patients with type 2 diabetes.

Half of the patients were randomized to a placebo group while the other half received amlexanox for three months. Blood sugar, insulin sensitivity, weight and liver fat were measured. A biopsy of fat cells from each patients midsection was taken before and after the trial to measure changes in gene expression.

The most exciting part of this is that we have a new drug that has never been studied before, says Saltiel. Its a new mechanism for a diabetes and fatty liver drug. Its promising, but there are a lot of questions that need to be answered still.

Among them: Which gene changes are the most important to target? Whats the right drug dosage? What time of day should it be administered? How often should patients take the drug? Can the percentage of responders be increased? Will the beneficial effects of the drug be sustained for a longer time?

One-third of the participants in the blinded study responded. Among responders with nonalcoholic fatty liver disease, an improvement was also seen.

Researhers are planning follow-up trialsto look at whether its possible tostratify patients who are likely to respond based on the degree of underlying inflammation, and explore if other drug combinations can be used with amlexanox.

We are grateful for patient participation and hope that our patients will respond with the same enthusiasm to our new trials. Without patients volunteering, the sort of study can never happen, says Oral.

Primary support for the research came from the National Institutes of Health High Risk High Reward grant R21DK098776.

Twitter reacts to Rob Kardashian’s revenge porn posts on Instagram – SHEmazing

Over the course of the last thirty minutes, Rob Kardashianhas posted multiple intimate shots of Blac Chynaon Instagram in a move which has led many to question Rob's current state of mind.

After claiming that the mother of his baby daughter, Dream, has been cheating on him, 30-year-old Rob uploaded photos which featured Chyna in various states of undress.

In addition to these graphic uploads, Rob went on to upload footage which shows Chynabefore undergoing weightloss surgery which he says she denies.

"Everyone wonders how Chyna lost all that weight after the baby and she lies to everyone but no I'm such a great Husband that on our anniversary I paid 100K to do this surgery to get all everything fixed as much as they could," he wrote in the controversial upload.

"And then guess what she did after she was all healed when I was by her side the entire time. She left me and my baby which she had out of spite to get back at her other baby daddy. I can't believe u would disrespect me like this."

Rob's decision to circulate nude images ofhis partner coincided with claims that she abuses alcohol and drugs, with one of Rob's post alluding to the quantity of alcohol she ordered to her home recently.

"U will never see Dream again unless u stop the alcohol and drugs and cocaine and X ad E. lol. That's called a party pack," he wrote.

A world without tigers? No way, says this beer company – Star2.com

Can you imagine a world without tigers? Can you imagine a day when these large, majestic cats are gone from the planet forever? Well, you can stop imagining now, because that could actually become a reality.

Globally, wild tigers are endangered their numbers have dropped 96% in the last century, from an estimated 100,000 to as few as 3,890 today.

The illegal tiger trade is one of the main reasons they are disappearing. More than a hundred tigers are killed each year, their body parts sold for profit through international criminal networks. Every part of the tiger, from skin and bones, to whiskers and teeth, is exploited and used to make products such as medicine, ornamental accessories, and textiles.

Today, the illegal tiger trade and the wider problem of wildlife trafficking reaches an estimated US$20bil (RM85.8bil) per year.

With that in mind, Tiger Beer has launched 3890Tigers, a digitally-led campaign that uncages art and creativity to raise global awareness of the plight of wild tigers.

By uploading a selfie on 3890Tigers.com, users can personalise their picture before posting it on social media to show their support.

3890Tigers (the name comes from the number of wild tigers left) is part of a six-year project in support of Tx2, a global commitment made by the governments of the 13 tiger range countries, including Malaysia, to double the worlds wild tiger population to 6,000 by 2022.

Tiger Beer kicked off the campaign with a donation of US$1mil (RM4.3mil) to organisations that support tiger conservation.

To drive home the urgency of the situation, it has also temporarily removed the tiger from its logo and is introducing a limited-edition design on select packaging without the iconic tiger for the first time in 84 years all to symbolise the threat of wild tigers disappearing.

Working in partnership with six artists from around the globe Malaysias Kenji Chai, Chinas Hua Tunan, Frances Mademoiselle Maurice, Russias Nootk, Britains Nick Gentry and the United States Tran Nguyen Tiger Beer has released an online tool which allows people to instantly create one-of-a-kind selfie art generated by AI.

Tiger Beer has removed the tiger from its logo and introduced a limited-edition design on select packaging without the iconic tiger for the first time in 84 years.

By uploading a selfie on 3890Tigers.com, users can choose from a range of signature styles including enigmatic street-art-meets-calligraphy, delicate paint and ink illustrations and fluttering rainbow origami to personalise their picture, before posting it on social media to show their support.

The campaign will conclude with a showcase event at Publika Mall in Kuala Lumpur, on Global Tiger Day (July 29). Art from the six artists will be on display alongside 250 individual tiger art pieces from local artists, symbolising the estimated number of Malayan Tigers left in the wild.
