This Is the Dangerous Condition You Can Get from Spin Class – Brit + Co

With a cult-like following among city dwellers and a rep forbringing you both spiritual enlightenment and the best butt of your life, its easy to understand why so many people are jumping on a spin bike, enthusiastic to finally experience those intoxicating endorphins for themselves. But with such a high-intensity workout comes a higher chance of doing something wrongand either hindering yourself from itsfull benefits or seriously hurting yourself. In fact, both spin class and CrossFit (two seriously intense and majorly trendy workouts) have been linked to Rhabdomyolysis (rhabdo for short), a potentially life-threatening condition that occurs when your muscles break down and release toxins into your bloodstream. While its not super common, its still important to understand, especially if youre considering taking a spin class for the first time. So before you start making the most of that ClassPass membership, be sure to read on for Dr. Jacqueline DuBoses explanation of rhabdo, what you can do to prevent it, and what signs to look for if you think you might have it. As always, if you have an immediate medical concern, please seek professional help immediately!

Brit + Co: What is Rhabdo?

Jacqueline DuBose: Whenever muscle cells are destroyed, various proteins are released into the bloodstream and cleared from the body through the kidneys, and to a lesser extent the liver. Rhabdomyolysis occurs when large amounts of muscle cells are destroyed simultaneously, and theproteins that are released overwhelm the kidneys.

B+C: How does a person get it?

JDB: This usually occurs in skeletal muscle injuries, such as crush injuries in an automobile accident, or large, deep burns from a fire. Certain medications can also cause rhabdomyolysis. Less frequently, we see it resulting from intense, prolonged exercise. The typical case of rhabdo in this circumstance used to be an untrained military recruit; however, we are seeing it more in the general population.While its still considered rare, the recent surge in popularity of high-intensity interval training (HIIT) has certainly contributed to the rise in ER visits for rhabdomyolysis.

B+C: How can you prevent it?

JDB:Of the documented cases resulting from spinning, the vast majority occurred after the first class. Newbies should start slow, and gradually increase the intensity and duration of exercise over several weeks. Consider limiting the first spin to 15 minutes, then see how you feel over the next two days. Drinking water before, during, and after the session will help keep the kidneys working properly. Adequate rest between vigorous exercise sessions is also critical for muscle recovery. Just to be on the safe side, do not use non-steroidal anti-inflammatory medications like ibuprofen or naproxen after a vigorous workout, as these put additional stress on the kidneys.

B+C: What are the telltale signs and symptoms?

JDB: Symptoms of rhabdomyolysis vary from person to person. For many, the first sign may come during exercise, with a feeling of tightness and fatigue. Muscle pain is usually progressive over the next 12-48 hours, much worse than the typical muscle soreness of a good workout. The quadriceps (thigh muscles) are especially prone to swelling, and it may become difficult to bend the knees or walk. In many cases, urine may turn dark or tea-colored, as the kidneys attempt to clear the proteins.

B+C: What can happen to someone who has it?

JDB: Rhabdomyolysiscan belife-threatening. If you think you have it, itsimperative to seek medical attention early to avoid kidney and muscle complications, or even death. In most cases, rhabdomyolysis can be successfully treated in the hospital with a few days of intravenous fluids and rest, followed by more oral hydration and rest at home. Delaying care can result in kidney damage requiring dialysis, or permanent muscle damage from compartment syndrome, a condition in which the swelling is so extreme, the muscle tissue starts to die.

B+C: Should we be worried?

JDB: A common-sense approach is key to preventing rhabdomyolysis. Fear of developing rhabdo should not deter you from starting an exercise program, but you should be aware of the risks!

International Space Station astronauts to view the solar eclipse 3 times – AccuWeather.com

While millions of Americans gather across the country to catch a glimpse of Monday's total solar eclipse, the astronauts aboard the International Space Station will view the event from a much different vantage point.

The ISS crew members are predicted to view both a partial eclipse and the moon's shadow cast on the North American continent as they make three tracks around the planet 400 km above Earth's surface, according to NASA.

"Observing a total solar eclipse from manned spacecraft is difficult though not impossible," NASA reported.

NASA said the different rates of speed and intersecting paths are the main challenge to viewing an eclipse from space.

At minimum, ISS spends less than 15 seconds traversing the 100-km-wide lunar shadow even when the paths align in space and time, according to NASA. However, Earths horizon extends nearly 2,300 km from the ISS, allowing astronauts to see the lunar shadow if they are close enough during the event.

NASA

The International Space Station (ISS) was in position to view the umbral (ground) shadow cast by the moon as it moved between Earth and the sun during a solar eclipse on March 29, 2006. This astronaut image captures the umbral shadow across southern Turkey, northern Cyprus and the Mediterranean Sea. (Photo/NASA)

The total eclipse will begin on the Oregon coast at 17:15 UT (10:15 a.m. PDT) and will end along the South Carolina coast at 18:49 UT (2:49 p.m. EDT).

As the space station makes its first pass during the eclipse, the crew members will be able to view a partial solar eclipse with approximately 37 percent of the sun covered up, NASA reports.

However, at this point in time, the ISS will not be able to see the umbra, or the darkest part of the moon's shadow on the Earth's surface. The space station will pass over the western United States and southeastern Canada in the first pass. The total portion of the eclipse will not have started yet for the Earth.

As the station makes its second pass through the moon's shadow, the partial eclipse will be visible to the astronauts with 44 percent of the sun covered.

"ISS will witness the moons umbra moving from southwestern Kentucky to northern Tennessee during a portion of this pass," NASA reports.

"The moons umbra is visible on the Earth from ISSs viewpoint while ISS traverses from southern Canada just north of the Montana-Canada border to the Gulf of Saint Lawrence."

At its closest approach, the space station will be making its way south of the Hudson Bay, far removed from the moon's umbra, which will be passing over southwestern Kentucky nearly 1,700 km away.

However, despite the distance, crew members aboard the ISS should still be able to view the shadow near the horizon.

The third pass for the ISS will bring another view of a partial solar eclipse with 85 percent coverage just minutes before orbital sunset. At this point, the darkest part of the lunar shadow will no longer be visible to crew as the umbra will have lifted from the Earth's surface as it makes its transit.

"Because of atmospheric friction and other ISS activities, the orbits undergo small changes from week to week," NASA reports.

The most precise timing will be available on NASA's ISS observations website.

Boy Scouts Launch Science Project To International Space Station – CBS Chicago

August 15, 2017 10:46 AM By Bernie Tafoya

CHICAGO (CBS) A Boy Scout troop from the northwest suburbs got a chance to see their dreams and more lift-off into space on Monday.

Andrew Frank, 16, and several other scouts from Troop 209 in Palatine were at the Kennedy Space Center in Florida, and other members of their troop were at a watch-party in Arlington Heights, as a Space X Falcon 9 rocket took off, carrying the scouts science experiment to the International Space Station.

We were all counting down with the clock as it launched off. It was really a big sense of excitement with the whole team, Frank said minutes after the rocket headed into orbit. Everyone kind of cheered and threw their arms up in the air when it actually launched. It was really cool.

Adult project lead Norm McFarland said the experiment was designed to see whether an organism in this case, E. coli mutates at a different rate in low gravity.

We think there could be implications here for either tissue growth or maybe something in cancer research, McFarland said.

Frank and his team of about a dozen scouts put in more than 5,000 hours of work on the experiment before launching it into space.

When we get our data back, were going to have to go through all the pictures, all the data. Were going to have to analyze it, and put together our report, he said.

McFarland said it will take at least three months to analyze all the data once the 24-day experiment on the station has been completed. He said the experiment will result in 6,200 pictures, each containing 70 pieces of biological information.

Frank said he and his fellow scouts likely have checked off a number of requirements for several merit badges by working on the experiment.

McFarland said the project began two years ago, with leaders suggesting the idea of trying to get an experiment in space. He said 84 suggested experiments were whittled down to two that were merged into the experiment that is now up in space.

Im a lifelong Chicagoan and could never see myself living anywhere else (except maybe Hawaii!). I was born on the North Side in 1958 but have lived all but the first three months of my life on the South Side. That said, thank (or is that curse?)...

Tacoma review: A slow-burning space station mystery – Stuff.co.nz

LEE HENAGHAN

Last updated20:32, August 15 2017

What caused the six crew members of an orbital space station to abandon ship? Tacoma is a deep space detective game.

Exploring an abandoned space station after a disaster left the crew fighting for their lives sounds like the perfect set-up for a thrill-a-minute action game or nail-biting survival horror. Tacoma couldn't be further removed from that end of the gaming spectrum.

It's a seriously slow burner that makes Fullbright's previous "walking simulator" hit Gone Home feel like a Bayonetta boss battle.This is a game that you take at your own pace, soaking it in as youanalysetiny details.

There's no intense combat, no terrifying enemies or world to save. If you prefer your games to be a little more dynamic and exciting, then Tacoma probably won't be your cup of tea.

If, however, you're a fan of gripping narratives, fascinating characters and brilliantly delivered dialoguethen this is well worth checking out. I found it difficult to put down and enjoyed pretty much every minute of it

Captured conversations between the station's crew members are replayed by the Tacoma AI, allowing you to piece together the events that led up to the mysterious disaster.

Playing as security contractor Amy Ferrier, you arrive on the lunar orbital space station Tacoma in the wake of a orbital debris collision which destroyed the facilities communication mast and wiped out most of its oxygen supply.

The six-person crew that manned the station are nowhere to be found. It's your job to move from section to section, downloading data from the ship's AI system in an attempt to piece together what went wrong, and work out where the hell everybody went..

The good news is that the AI recorded everyinteraction between the crewmates during the year leading up to the accident. The bad news is that much of that data appears to have been corrupted or destroyed.

Most of the Tacoma station is covered by the installation's artificial gravity system, but travelling between each section is done in zero-g, allowing you to get your float on.

This means that you although you can access snippets of conversations, played out in real time by augmented reality figures that move around the Tacoma station. there are gaping holes in the narrative which you need to fill by fleshing out the characters' back-stories and exploring their abandoned home.

Effectively, you experience Tacoma as a series of theatrical plays, as you move from room to room, recovering the data and watching the 2-10 minute conversations with the crew unfold. Sometimes, characters will move around the facility as they're talking, requiring you to follow individuals around before rewinding and going back to see what everyone else was saying while you were away.

Full credit must go to the writing team and voice acting cast. The story is perfectly paced and delivered in fine style. The AR models have no facial features so the drama is conveyed entirely via dialogue and body language.

Exploring the various rooms and living quarters will uncover more clues and vital details about the station's inhabitants.

Despite the sci-fi setting, Tacoma is essentially a story about relationships. Not just between the crew members but between their friends and family on Earth and thecorporate overlords running the show.

You're also able to download data from character;s AR desktops (although much of this is also corrupted) giving you an insight into their lives via email chains, internet browsing history and image files.

Perhaps the creepiest part of the game though , is how you'reactively encouraged to go snooping through the crew's private living quarters looking for clues and items of interest.

Food wrappers, postcards, cups, coins and mementos. Every item you see on board the Tacoma can be picked up and pored over.

There's a certain voyeuristic thrill about searching through drawers, lockers and bedside tables and although some of the details you uncover arefascinating, it's hard not to feel like it's all a massive invasion of privacy.

It's also interesting how much of the junk and random items of interest have absolutely no bearing on the story whatsoever, but picking them up and analysing them somehow adds even more depth and realism to the experience. In most games, everything is there for a reason and it's rare to see a pixel wasted on something that doesn't serve an obvious purpose.

In Tacoma, scribbled notes, postcards, crumpled space-food wrappers, even a casually discardedsex toy in one couple's bedroom, have no real reason to be there, other than to make the abandoned space station feel like a real place, where real people lived, laughed and loved for a year prior to your arrival.

Tacoma isn't a particularly long game. Depending on how distracted you get and how deep you delve into the facility's nooks and crannies, you'll probably get through it in a few hours. You probably won't be too keen to replay it againeither - it's not a branching narrative game where your choices have a bearing on the ending or how events unfold.

It will almost certainly stay with you though, it's an innovative and interesting experience in interactive storytelling that you won't forget in a hurry.

SpaceX launches most powerful computer ever sent to space station – KPRC Houston

NEW YORK - A SpaceX rocket is ready to deliver one of the most high-tech payloads ever to the International Space Station.

When the Falcon 9 rocket blasts off on Monday, one of the items on board will be a supercomputer built by Hewlett Packard Enterprise, dubbed the "Spaceborne Computer." If it works, it could be the most powerful commercial, off-the-shelf computer ever to operate in space.

Astronauts aboard the space station already have a bunch of devices you'd find at your local electronics store -- including HP laptops.

But a supercomputer is something different. It's a much more powerful piece of hardware that can crunch massive amounts of data and send the results to other computers in just moments.

According to Mark Fernandez, the HPE engineer who is heading up this new experiment, the space-bound supercomputer will have the ability to make one trillion calculations in a single second -- about 30 to 100 times more powerful than your average desktop computer.

Julie Robinson, the chief scientist for NASA's space station program, said if this supercomputer can function in the harsh conditions of space -- it'll be very exciting news for companies down here on earth.

Robinson points out that a huge point of interest for the private sector is taking high-quality satellite images of earth in order to track things like crop growth or oil exploration.

"What's happening is -- just as your TV now has so much more resolution -- the same thing is happening with [satellite imagery]," she said.

But the high-definition images require 200 to 300 times more data, which can clog up the communication pipeline between earth and space. That's where a supercomputer on board the space station would become hugely valuable, Robinson told CNNMoney.

"If you can process the data on board [the space station], you then only need to send down a subset of the data that's actually needed," she said.

Space-bound computers have been slow to reach such powerful data processing capabilities. A lot of the hardware on board the space station now has undergone significant retrofitting via a process called "hardening" -- which means it's been beefed up with extra protection to keep it safe in the rough conditions of space.

"By the time it goes through the hardening process, and then the tests needed to ensure it's ready to fly, the computers are many generations old," HPE's Fernandez said.

HPE's supercomputer, however, is just like one you'd buy on earth. Fernandez said the only thing different about the one flying to space is some special software that should be able to detect when the computer is exposed to something dangerous -- like high radiation levels -- and make small adjustments to keep it safe.

Will the avant-garde software be enough to ensure the supercomputer will survive in space?

Not everyone is so sure. "Some think it'll never power up or be fried within the first few minutes," Fernandez said.

We'll find out soon enough.

Fernandez said he expects to receive word the device has been plugged in and booted up sometime on September 4.

"I told them to let me know as soon as that happens -- anytime, day or night," Fernandez said with a laugh. "If it powers up, that's going to be my first relief. I will be very excited then."

Fernandez and his team will then run about 2-and-a-half hours of tests to determine if the computer is fully functional. That, he said, will be the next major victory.

Then, the plan is for scientists here on earth to keep running tests with the supercomputer for a full year to see how it fares on the space station.

If the supercomputer is still operational at the end of one year -- Fernandez said it'll pave the way for NASA to send up even more powerful computers.

And one day, a similar computer could be used by astronauts traveling to Mars.

HPE's Fernandez and NASA's Robinson both said having the ability to process large amounts of data on board a Mars mission would be a huge advantage.

That's because there could be long minutes of lag time in communicating with Mars-bound astronauts, and communications could even be cut off for days at a time.

"Such a long communication lag would make any on-the-ground exploration challenging and potentially dangerous if astronauts are not able to solve certain problems themselves," HPE explained.

"By sending a supercomputer to space, HPE is taking the first step in that direction," the company said.

Cosmic-ray detector heads to the International Space Station – physicsworld.com

NASA has launched a space-based probe that will study the origins of highly energetic particles, known as cosmic rays. Sent into space by a Space X rocket yesterday, the Cosmic Ray Energetics And Mass for the International Space Station (ISS-CREAM) will now be installed on the Japanese Experiment Module, where it will study cosmic rays for three years.

Cosmic rays zoom through space at nearly the speed of light and consist of a range of particles from protons to carbon atoms. When cosmic rays enter the Earth's atmosphere they collide with another particle setting off a cascade of secondary particles. While Earth-bound detectors only see the secondary particles, a probe that is above Earth's atmosphere will be able to spot the primary particles.

ISS-CREAM is a successor to six similar missions that have flown on long-duration balloons, which began in 2004 with the first flight of the Cosmic Ray Energetics and Mass mission. "The mysterious nature of cosmic rays serves as a reminder of just how little we know about our universe," says Eun-Suk Seo from the University of Maryland, who is the lead investigator for ISS-CREAM. "This is a very exciting time for us as well as others in the field of high-energy particle astrophysics."

New thruster design increases efficiency for future spaceflight – Phys.Org

August 15, 2017 The vortex exhaust mode on low-power cylindrical Hall thruster. Credit: Wei Liqiu, Harbin Institute of Technology, China

Hall thrusters (HTs) are used in earth-orbiting satellites, and also show promise to propel robotic spacecraft long distances, such as from Earth to Mars. The propellant in a HT, usually xenon, is accelerated by an electric field which strips electrons from neutral xenon atoms, creating a plasma. Plasma ejected from the exhaust end of the thruster can deliver great speeds, typically around 70,000 mph.

Cylindrical shaped Hall thrusters (CHTs) lend themselves to miniaturization and have a smaller surface-to-volume ratio that prevents erosion of the thruster channel. Investigators at the Harbin Institute of Technology in China have developed a new inlet design for CHTs that significantly increases thrust. Simulations and experimental tests of the new design are reported this week in the journal Physics of Plasmas.

CHTs are designed for low-power operations. However, low propellant flow density can cause inadequate ionization, a key step in the creation of the plasma and the generation of thrust. In general, increasing the gas density in the discharge channel while lowering its axial velocity, i.e., the speed perpendicular to the thrust direction, will improve the thruster's performance.

"The most practical way to alter the neutral flow dynamics in the discharge channel is by changing the gas injection method or the geometric morphology of the discharge channel," said Liqiu Wei, one of the lead authors of the paper.

The investigators tested a simple design change. The propellant is injected into the cylindrical chamber of the thruster by a number of nozzles that usually point straight in, toward the center of the cylinder. When the angle of the inlet nozzles is changed slightly, the propellant is sent into a rapid circular motion, creating a vortex in the channel.

Wei and his coworkers simulated the motion of the plasma in the channel for both nozzle angles using modeling and analysis software (COMSOL) that uses a finite element approach to modeling molecular flow. The results showed that the gas density near the periphery of the channel is higher when the nozzles are tilted and the thruster is run in vortex mode. In this mode, gas density is significantly higher and more uniform, which also helps improve thruster performance.

The investigators verified their simulation's predictions experimentally, and the vortex inlet mode successfully produced higher thrust values, especially when a low discharge voltage was used. In particular, the specific impulse of the thruster increased by 1.1 to 53.5 percent when the discharge voltage was in the range of 100 to 200 Volts.

"The work we report here only verified the practicability of this gas inlet design. We still need to study the effect of nozzle angle, diameter, the ratio of depth to diameter and the length of the discharge channel," Wei said. He went on to predict that the vortex design will be tested in flight-type HTs soon and may eventually be used in spaceflight.

If rumors that have been circulating prove to be true, the SES-11 satellite launch, currently scheduled for no earlier than September 27, 2017, may fly on a flight-proven SpaceX Falcon 9 booster.

CAPE CANAVERAL, Fla. The SES-11 satellite (sometimes referred to as EchoStar 105) will provide satellite based television to customers across North America. It is designed to replace functions currently being provided by two different satellites currently in orbit.

Accordingto a statement on the SES website: The spacecrafts Ku-band capacity will replace AMC-15 at 105 W, an orbital position where EchoStar has been our anchor customer since 2006. The spacecrafts C-band capacity will provide replacement capacity for AMC-18 at the same position.

SES has already launched one satellite using a previously flown Falcon 9 booster. On March 30, 2017, the SES-10 satellite became the first geostationary satellite to be placed into orbit using a flight-proven first-stage booster.

Following the successful launch, SpaceX recovered the booster for the second time; additionally, they also were able to recover one-half of the payload fairing, a first for any launch provider.

At a news conference following the successful SES-10 launch, Martin Halliwell, Chief Technology Officer from SES, stated: We have 3 more flights this year with SpaceX, on two of those flights we are considering now moving them to pre-flown.

So SES-11 could be one of those two flights that Halliwell was referring to.

SpaceFlight Insider reached out to SpaceX to try and get confirmation, either way, on whether a flight-proven Falcon 9 booster would be used for SES-11, but we have not received an answer from them as of this writing.

Using a flight proven booster offers substantial launch cost savings over a brand new booster. While SpaceX hasnt quoted specific pricing, it saves the customer millions of dollars for a launch.

SpaceX continues to improve the Falcon 9 booster in efforts to hopefully turn it around to fly again in a short period of time. SpaceX founder and CEO Elon Musk has a goal of a 24-hour turnaround time to fly again.

SES-11 is now third in line on the SpaceX launch manifest. Following the successful CRS-12 launch yesterday, August 14, a resupply mission to the International Space Station, SpaceX will first focus on the Formosat 5 Earth-observation satellite launch on August 24, 2017, from SLC-4E at Vandenberg Air Force Base in California.

Then they will tackle a very high profile launch from LC-39A at the Kennedy Space Center. The OTV-5 launch will mark the first time SpaceX has lofted the U.S. Air Forces experimental X-37B unmanned spacecraft into orbit. That launch is currently slated for September 7, 2017.

Lloyd Campbells first interest in space began when he was a very young boy in the 1960s with NASAs Gemini and Apollo programs. That passion continued in the early 1970s with our continued exploration of our Moon, and was renewed by the Shuttle Program. Having attended the launch of Space Shuttle Discovery on its final two missions, STS-131, and STS-133, he began to do more social networking on space and that developed into writing more in-depth articles. Since then hes attended the launch of the Mars Science Laboratory Curiosity rover, the agencys new crew-rated Orion spacecraft on Exploration Flight Test 1, and multiple other uncrewed launches. In addition to writing, Lloyd has also been doing more photography of launches and aviation. He enjoys all aspects of space exploration, both human, and robotic, but his primary passions lie with human exploration and the vehicles, rockets, and other technologies that allow humanity to explore space.

CAPE CANAVERAL, Fla. In November 2016, the GOES-Rspacecraft, part of the Geostationary Operational Environmental Satellite (GOES) system, was launched. It was the first in a new class of weather monitoring satellites built for the National Oceanic and Atmospheric Administration (NOAA). After transitioning to a geostationary orbit, it gained a new name GOES-16. Now two of the follow-up spacecraft, GOES-S and GOES-T, are on track to be completed and launched as scheduled.

Next in the series, GOES-S is undergoing final testing to confirm functionality. These evaluations are designed to confirm the spacecraft can withstand the rigors of launch and operation, including mechanical stresses and the thermal extremes of space.Additional electromagnetic testing will be performed to ensure the electronics on the spacecraft will not interfere with its operation.

Testing for GOES-S will continue through Fall 2017, after which it will be sent to Kennedy Space Center for final launch preparations. That shipment is scheduled to occur in December.

The GOES-R series of satellites is a collaborative effort between NOAA and NASA. The spacecraft are designed to monitor Earths oceans, land, and atmosphere providing weather forecasting, storm tracking, and climate information. Additionally, the satellites are used for space weather modeling and meteorological research.

GOES-S is now in its final test phase preparing it to join GOES-16 in space, giving the nation two next-generation geostationary weather satellites to watch over the Western Hemisphere, said acting GOES-R Series System Program Director Mike Stringer at the GOES-R Series Program Office located at NASAs Goddard Space Flight Center in Greenbelt, Maryland.

Designed for a 10-year operational life, the Lockheed Martin-manufactured GOES-R spacecraft are builton the A2100satellite bus, a three-axis stabilized platform. Fully fueled, the vehicles each have a mass of 11,446 pounds (5,192 kilograms) at liftoff. Instrumentation on the GOES-R series includes Earth facing and solar facing electronics packages. In total, the series will have 34 meteorological, solar, and space weather equipment packages.

GOES-T is also well into production. Five of its on board instrument packages have been delivered to Lockheed Martins facility in Littleton, Colorado. The majority of the avionics have been installed as well as the Solar Ultraviolet Imager (SUVI) and the Extreme Ultraviolet and X-ray Irradiance Sensors (EXIS). Integration tests for these components are underway. Additionally, the propulsion module was delivered in July and the two spacecraft halves are scheduled to be mated together sometime in September.

This entire series of satellites boosts the capacity of weather monitoring due to the incredible advancement of environmental sensors. The spacecraft have four times the viewing resolution of previous GOES satellites. They can also scan the Earth five times faster and boast triple the number of channels for more accurate and reliable forecasts. Additionally, the GOES-R series will monitor solar and space weather activities.

Calling all Redheads the countdown to Oranges red letter day has begun.

There are only 50 days to go until redheads from all over are being urged to head to Wade Park on September 30 and join in the fun.

It will culminate in an attempt to break the world record for the most redheads in the one place at the one time.

The current record stands at 1672members of the ginger army.

Organiser Rachael Brooking announced actor and writer and redhead Stephen Hallwould be the MC for the four-hour event to run from 11am-3pm.

She said she had lined up guests ranging from Ronald McDonald to singer Joel Leffler who would be releasing his new single Auburn Hair in September and the Honey Drippin Mudskippers Band.

It is going to be a fun family festival, she said.

All redheads are being encouraged to wear white for the event.

And while true redheads will only be allowed in the official count Mrs Brooking said non-redheads were encouraged to join in.

Were encouraging non-redheads to spray, colour or don a red wig for the event, she said.

And blokes with red beards, the festival is looking for you.

There will be a red beard competition, she said.

Well be looking for the longest, bushiest, most manicured and even the reddest, she said.

The red theme will be splashed through the food, drink and merchandise stands.

That would include red apples, toffee apples, orange juice, ginger ale and red slushies for sale plus red wig and redhead merchandise stalls.

Mrs Brooking said there would be a cliff hanger and jumping castle plus face painting to entertain the children.

The Rural Fire Service is bringing a shiny new red fire truck.

Red and orange vintage and custom cars will also be on show.

And your big day at the festival will be captured by photographer Chris Rehberg of Oatley Photography.

Mrs Brooking said he would be doing portraits and was looking to do a book to commemorate the day Orange turns red.

Mrs Brooking said there would be a gold coin entry fee with proceeds to go toward supporting familiesof people with Huntingtons Disease [HD] as September is HDawareness month.

She is also organising the screening of theThe Inheritance, which showsa familys journey with HD, on September 1, Walk for Hope Orange and Tea with Gatsby-High Tea4HD at Kenna Hall on September 16 to raise funds and awareness for HD.

Mrs Brooking said she was still looking for businesses and groups to be involved.

Why NASA is sending bacteria into the sky on balloons during the eclipse – The Verge

As the Moon blocks the Suns light completely next week in a total solar eclipse, more than 50 high-altitude balloons in over 20 locations across the US will soar up to 100,000 feet in the sky. On board will be Raspberry Pi cameras, weather sensors, and modems to stream live eclipse footage. Theyll also have metal tags coated with very hardy bacteria, because NASA wants to know whether they will survive on Mars.

Every time we send a rover to the Red Planet, our own microorganisms latch on to them and hitch a ride across space. What happens to these bacteria once theyre on Mars? Do they mutate? Do they die? Or can they continue living undisturbed, colonizing worlds other than our own? To answer these questions we need to run experiments here on Earth, and the eclipse on August 21st provides the perfect opportunity.

I said, oh my god, thats like being on Mars!

The balloons are being sent up by teams of high school and college students from across the US as part of the Eclipse Ballooning Project, led by Angela Des Jardins of Montana State University. When Jim Greene, the director of planetary science at NASA, first heard that over 50 balloons were being flown to the stratosphere to live stream the eclipse, he couldnt believe his ears. I said, oh my god, thats like being on Mars! Greene tells The Verge. NASA couldnt pass on the opportunity.

The upper part of the Earths stratosphere just above the ozone layer is very much like the surface of Mars: its about minus 35 degrees Fahrenheit, with very rarified air, and its hammered by the Suns ultraviolet radiation. During the eclipse, conditions will get even more Mars-like: the temperatures will go down even further, and the Moon will buffer some of those ultraviolet rays to better resemble the radiation on the Red Planet. Its really quite an outstanding astrobiology and planetary protection experiment, Greene says.

The bacteria that will fly to the edge of space is a particular strain called Paenibacillus xerothermodurans. It was first isolated from soil outside a spacecraft-assembly facility at the Kennedy Space Center in Florida in 1973, says Parag Vaishampayan, an astrobiologist at NASAs Jet Propulsion Laboratory. These bacteria form shields of spores that allow them to survive even when conditions turn deadly. It takes around 140 hours at 257 degrees Fahrenheit to kill 90 percent of these bacteria, Vaishampayan tells The Verge.

These are some of the most resilient types of bacteria that we know of, says David J. Smith, a researcher in the Space Biosciences Division at NASA's Ames Research Center.

Last week, Smith finished mailing the bacteria which are not dangerous for people or the environment to the student groups. (Only 34 of the balloons will carry the bacteria.) The microorganisms are dried onto the surface of two metal cards the size of a dog tag. One card will fly to the stratosphere, while one will remain on the ground to function as a control group. On eclipse day, the balloons will launch every 15 minutes or so from states that are in the path of the Moons shadow, Des Jardins says. Theyll fly for about two hours, reaching the stratosphere and eventually popping because of the pressure drop. Once theyre back on the ground (a parachute will slow down descent), the students will track them by GPS, recover the metal tags, and mail them back to NASA.

Thats when Vaishampayan and Smith will get to analyze how many bacteria have died, and whether their DNA has changed in any way. If some of them survive the flight, that might mean that these bacteria may have already survived a trip to the Red Planet as hitchhikers on a Mars rover. We dont know for sure whether Paenibacillus xerothermodurans is actually on any Mars rover. (It was found outside the spacecraft-assembly facility, not on the spacecraft themselves, Vaishampayan says.) But even if its not, learning more about these resilient bacteria could help us understand how similar ones could behave on Mars, and help NASA better understand the risk of infecting other worlds.

After all, we send million-dollar spacecraft to other planets and moons to search for alien life, so it makes sense that wed want to make sure these places are protected from Earths germs. Pushing organisms to the known limits of life can also help NASA find that life. If we know that resilient bacteria cant withstand certain conditions, then we wont look for life when those same conditions are found on other planets, Smith says.

I dont think its ever been done.

NASA has conducted very few experiments with high-altitude balloons, and none with this particular strain of bacteria. So flying over 30 balloons at once, under such perfect Mars-like conditions that wont be possible to replicate in the lab, is an amazing opportunity. I dont think its ever been done in terms of a coordinated astrobiology experiment happening across the entire continental United States on the same day, Smith says. This is spatial coverage that one could never dream of in other circumstances.

Greene hopes the experiment will also inspire the next generation of astrobiologists and planetary protection officers. He got into science when he was in high school and had the chance to use an observatory telescope to observe the Sun. Taking part in the Eclipse Ballooning Project might do the same for the students flying the balloons. You never know what turns kids on [to science], Green says. You never know how excited they can be.

Rare NASA flight suits sell for pennies at thrift store – CNET

And you thought you had a nose for bargains. Two college students discovered a set of NASA flight suits at a thrift store in Titusville, Florida, and paid 20 cents per outfit for the rare finds. WKMG in Orlando shared news of the bonanzaon Monday.

Talia Rappa and Skyler Ashworth hit up the blow-out discounts at a Salvation Army thrift shop that was going out of business, and Rappa discovered five blue flight suits and one white suit below a pile of sweaters. The American Space Museum in Florida says the suits are authentic. Names on the uniforms match those of NASA astronauts George Nelson and Robert Parker and payload specialist Charles Walker, all of whom flew on space shuttle missions in the 1980s.

Rappa and Ashworth both have connections to space. Rappa studies astrophysics at the University of Central Florida. Ashworth told WKMG his parents were involved with NASA communications during the shuttle program era and he plans to enter an aerospace program at Eastern Florida State College.

A tag inside one of the blue suits identifies it as a "launch/entry coverall" made by ILC Space Systems. The Smithsonian Institute says this type of suit was used in the shuttle program from late 1982 to 1986.

You may have missed out on picking up the NASA suits for a killer deal, but you can still own one. The American Space Museum is scheduled to auction the suits off on November 4. You'll just have to pay a lot more for them than Rappa and Ashworth did. The museum estimates they could sell for $5,000 (3,900, AU$6,400) each.

Here Are the Messages NASA Should Not Beam Into Deep Space – Gizmodo

NASAs Voyager 1 spacecraft is one of the universes only unproblematic faves. For over 39 years, its been cruising along in space, flying by Saturn and the Kuiper Belt, doing nothing but beaming back beautiful photos and scientific research. Now, the intrepid spacecraftskirting serenely in interstellar spaceis being bombarded with requests for nudes, the pee tape, and least predictably, questions about peoples dads.

For context: this September marks the big 4-0 for Voyager 1, which means it remembers the time before the internet, so it couldnt tweet lewd demands at the pope or look up Lemony Snickets real identity. So as Voyagers anniversary approaches, NASA is celebrating by asking the public to share messages for the wholesome spacecraft, using the hashtag #MessageToVoyager. One lucky winners message will be beamed to the space probe, which is nearly 13 billion miles from Earth.

This, predictably, was a mistake.

Join NASA in celebrating the Voyager missions 40 years of exploring space. Inspired by the messages of goodwill carried on Voyagers Golden Record, youre invited to send via social media a short, uplifting #MessageToVoyager and all that lies beyond it, NASA wrote. With input from the Voyager team and a public vote, one of these messages will be selected for NASA to beam into interstellar space on Sept. 5, 2017the 40th anniversary of Voyager 1s launch. (Emphasis ours because, well, youll see).

While some people tweeted pleasant platitudes at the innocent spacecraft, others were a bit more imaginative. Here are just some of the tweets that, for the sake of humanity, we hope NASA will not send into interstellar space:

And lastly:

Weve said it before, but Voyager is probably better off without us.

Rodents help NASA take the next step to Mars – Phys.Org

August 15, 2017 by Frank Tavares NASA astronaut Peggy Whitson collects images of the back of the eye during a routine check into astronaut eyesight. Crew members' bodies change in a variety of ways during space flight, and some experience impaired vision. Credit: NASA

NASA's future deep space exploration including to Mars is an unprecedented venture in spaceflight, requiring us to tackle challenges we've never faced before. For instance, we know the human body changes significantly while in space, and we'll need to find ways to address those effects. NASA is conducting research to learn more about the long-term impact of extended human spaceflight. One experiment that just launched, Rodent Research-9, is contributing to this goal by sending rodents to the International Space Station, to study how a lack of gravity in space affects blood vessels, eyes and joints.

Using transport and habitat technology developed at NASA's Ames Research Center in California's Silicon Valley, the mice will fly to the space station aboard the 12th SpaceX resupply mission, and return to Earth about a month later. Due to biological similarities to humans, the mouse is a good choice of model organism for research aimed at understanding biological changes caused by the space environment. By studying rodents in the short term, NASA can make predictions about long-term human biological change in space, with applications here on Earth as well.

"Space biology scientists have observed accelerated changes in mouse physiology in the space environment that are characteristic of some human diseases, such as osteoporosis and aging," said Kevin Sato, the project scientist for the space biology project at Ames. "Similar changes have been observed in astronauts, so the space environment allows scientists to study physiological changes in the astronauts using the mice as a model."

"We can also investigate physiological disease processes, which normally take years to develop, during the duration of a space flight investigation," said Sato. "The changes we see during this rodent research experiment will allow us to better prepare our astronauts for long-term exposure to low-gravity environments."

Three-in-One Mission Supports Future Human Space Exploration

With limited opportunities to send experiments to the space station the only true microgravity laboratory that exists NASA must use each mission to its full capacity.

For Rodent Research-9, the agency's space biology program is sponsoring three scientists from different universities to address different issues. NASA's bio-specimen sharing allows the three investigators to work with the same group of mice, without having to send three different missions to the space station. The three complementary research investigations will be combined into one cost-effective mission, addressing questions that are fundamental to human space exploration.

Two of the investigations will identify how microgravity affects blood vessels in the brain and in the eyes. Some astronauts on long missions on the space station find that their vision becomes impaired. The leading theory to explain this suggests that, without Earth's gravity, fluids shift from the lower to the upper body, causing an increase in pressure in the head and eye, leading to visual impairment. The experiments with mice will help test this theory.

Exposure to weightlessness also can cause tissue degeneration in hip and knee joints. The third experiment on RR-9 will look at cartilage loss in these joints. Researchers will study how the gait of the mice their manner of walking is changed by these conditions. Understanding how weightlessness affects cartilage will help NASA develop ways to counter these adverse effects, allowing humans to stay healthier in space for longer periods of time.

For humans here on Earth, rodent research related to limited mobility and degrading joints can help scientists understand how arthritis develops in people, and a better understanding of the visual impairments experienced by astronauts can help identify causes and treatments for eye disorders.

Don't Redesign the Wheel

NASA's ongoing series of rodent research investigations use a proven and standardized hardware system. For decades, Ames has designed, constructed and tested hardware for rodent research experiments, including rodent habitats, transporters and an animal access unit. This hardware is versatile and reusable, providing ongoing support for space-related rodent research carried out by NASA and its partners in industry and academia.

"This kind of in-depth research is possible because of the unique hardware Ames has been able to provide for rodent research," said Janet Beegle, rodent research project manager. "By transitioning from a payload system where a researcher's team would start from scratch each time we send up an experiment to a permanent hardware facility provided by NASA, we can have an ongoing and consistent rodent research presence on the station."

Through well-designed and cost-effective experiments such as Rodent Research-9, NASA is tackling the obstacles in our path to reaching Mars and beyond. With the knowledge gained by understanding how human biology thrives and changes in space, we can better serve human needs on Earth and beyond.

9-Year-Old ‘Guardian of the Galaxy’ Applies to Be NASA Planetary Protection Officer – Space.com

NASA's new Planetary Protection Officer role is responsible for making sure we don't contaminate other planets with Earth microbes, and avoid alien contamination of ours over the course of space exploration.

NASA's recent job posting for a planetary protection officer inspired a fourth-grader to become the next real-life guardian of Earth.

Nine-year-old Jack Davis, a self-proclaimed "guardian of the galaxy" from New Jersey, wrote a letter to the space agency highlighting his many qualifications for the position, which is intended to prevent interplanetary contamination during space missions.

"I may be nine but I think I would be a fit for the job. One of the reasons is my sister says I am an alien. Also, I have seen almost all the space movies and alien movies I can see," Davis wrote in the letter to NASA. [Best Space Movies in the Universe]

Fourth grade student Jack Davis wrote to NASA applying to be their new Planetary Protection Officer.

Davis also described his video game skills and ability to quickly learn new things. "I'm great at video games," he wrote. "I am young, so I can learn to think like an alien."

NASA responded to Davis' handwritten application, encouraging him to study hard and do well in school.

"At NASA, we love to teach kids about space and inspire them to be the next generation of explorers," Jim Green, NASA's planetary science director, said in a statement accompanying the letter. "Think of it as a gravity assist a boost that may positively and forever change a person's course in life, and our footprint in the universe."

In addition to the follow-up letter from Green, Davis received a phone call from Jonathan Rall, NASA's planetary research director. Rall congratulated Davis on his interest in working for NASA in the newly posted role.

NASA's planetary protection officer is responsible for protecting Earth from extraterrestrial microbes contained in samples brought back from human and robotic space missions to the moon, asteroids or Mars, according to the statement. It is also intended to prevent Earth visits from contaminating other planets that might host life.

Although Davis will have to wait a few years before he can work at NASA, the Liberty Science Center in New Jersey invited him to be the official kid science adviser of the Jennifer Chalsty Planetarium that is opening in a few months.

"I want you to know, I am standing in a space in which, in a few months, we are going to open the largest planetarium in the Western Hemisphere," Paul Hoffman, president and CEO of the Liberty Science Center, said in a video invitation to Davis. "I'd like you to be our first kid science adviser to the Jennifer Chalsty Planetarium here at Liberty Science Center."

NASA astrophysicist says Americans should be excited yet cautious with total solar eclipse on horizon – KWQC-TV6

WASHINGTON (Gray DC) - Less than a week away! The total solar eclipse slated for August twenty-first has Americans preparing for the rare event. It's the first time in nearly 100 years that a total solar eclipse will be visible across the entire United States.

"Most people don't get to see a total solar eclipse," said Hakeem Oluseyi, an astrophysicist at NASA.

Get it while it's hot, this rare event will not disappoint according to Oluseyi. A NASA astrophysicist, Oluseyi says the last time the U.S. had a coast-to-coast total solar eclipse was 1918. But why are they so rare?

"When the earth and the moon exactly lineup, that is a finite time in earth's history and we're here to witness it," said Oluseyi.

He says the moon will place itself perfectly in between the earth and the sun, blocking out the sun's light, turning day into night. Oluseyi wants this to be an education opportunity for every American...

"The people are the ones who have the interests and who put the passion in and become NASA scientists ultimately," said Oluseyi.

A fun, educational activity for every age group, Oluseyi says there are precautions that need to be taken. He says looking at the sun isn't safe and your regular sunglasses won't protect people during this eclipse.

"You don't want to look at the total solar eclipse with the naked eye. The only time you can do that is at the moment of totality itself. Other than that you have to use protective eyewear," said Oluseyi.

He says Americans should be wary of companies trying to take advantage of consumers by selling knockoff versions of these special shades.

"You have to get ISO certified glasses. And also, I encourage a person to look at the NASA website because their guidance is given in order to allow a person to determine what's fake and what's real," said Oluseyi.

Nanotechnology makes Solar Panels Beautiful – AZoCleantech.com – AZoCleantech

By Kerry Taylor-SmithAug 15 2017

Solar panels are attractive in terms of offering an alternative to the air-polluting fossil fuels which satisfy nearly 80% of the worlds energy demands, but they are not very attractive to look at.

However, the shiny blue and black panels littered across the landscape could become less of an eyesore, and blend in more with their surroundings thanks to new research from AMOLF - a research laboratory of the Netherlands Organisation for Scientific Research.

Scientists at the Amsterdam-based institute have developed a method for imprinting existing solar panels with silicon nanoparticles that scatter green light back to an observer. The panels have a green appearance from most angles, and show only a 10% power reduction due to the loss of absorbed green light.

It is hoped this step will make solar panels a more attractive technology to Architects, homeowners and to City Planners, as such installations could melt into the landscape, as could red panels on roofs, and white ones disguised as walls.

Some people say why would you make solar cells less efficient? But we can make solar cells beautiful without losing too much efficiency. The new method to change the colour of the panels is not only easy to apply but also attractive as an architectural design element and has the potential to widen their use.

Verena Neder, a Researcher in Photonic Materials at AMOLF and Lead Author of the Paper Published in Applied Physical Letters

Most research on solar cells focusses on increasing their efficiency and reducing costs; those currently sold to consumers ideally convert up to 22% of the suns light into usable energy. And while colored solar panels are on the market, the dyes and reflective coatings used to give them their color massively reduce their efficiency.

Neder and her colleagues were able to create their efficient green solar panels through soft-imprint lithography which works a bit like an optical rubber stamp to print a dense array of silicon nanocylinders onto the surface of the cell. Each nanocylinder is approximately 100 nanometers wide slightly smaller than the diameter of the HIV virus and exhibits an electromagnetic resonance that scatters a particular wavelength of light.

The geometry of the nanocylinder determines which wavelength it scatters and can easily be fine-tuned to change the color of the solar cells. The imprint reduces the solar panels efficiency by about 2%.

In principle, this technique is easily scalable for fabrication technology. You can use a rubber stamp the size of a solar panel that in one step can print the whole panel full of these little, exactly defined nanoparticles.

Professor Albert Polman, a Scientific Group Leader in Photonic Materials at AMOLF and Senior Author on the Paper

Unlike existing colored solar panels, the nanopatterns give a consistent appearance from different angles, The structure we made is not very sensitive to the angle of observation, so even if you look at it from a wide angle, it still appears green, Neder said.

The nanopatterns also could be useful in constructing tandem solar cells, which stack several layers, each designed to absorb certain parts of the spectrum, to achieve efficiencies of greater than 30%.

Next, the Researchers aim to design imprints to create red and blue solar cells. Once they master these three colors - the primary colors of light - they can create any color, potentially even white.

You have to combine different nanoparticles, and if they get very close to each other they can interact and that will affect the color. Going to white is a really big step.

Researchers develop nanotechnology test for Zika virus – Homeland Preparedness News

Researchers at Washington University in St. Louis recently developed a test that uses nanotechnology to quickly detect the Zika virus in blood.

Current Zika test requires the refrigeration of a blood sample in order to shop it to a medical center or laboratory. The recently developed tests results can be determined in minutes and does not require refrigeration.

The technology has not yet been produced for use in a medical situation, but the researchers tested blood samples from four people who were infected with Zika and five who did not. The test did not return any false positives.

With this test, results will be clear before the patient leaves the clinic, allowing immediate counseling and access to treatment, Jeremiah J. Morrissey, a research professor of anesthesiology who worked on the project, said.

The test uses protein made by Zika virus attached to tiny gold nanorods mounted on paper. The paper is coated with protective nanocrystals that enable the diagnostic nanorods to be shipped and stored without refrigeration before use.

To use the test, medical professionals wash the paper with slightly acidic water to remove the nanocrystals and then apply a drop of the patients blood. Blood that has been infected with the Zika virus contains immunoglobulins that react with the protein.

The nanorods will change slightly in color. This change can currently only be detected with a spectrophotometer, but the researchers are working to make it visible to the naked eye.

The researchers say similar strategies may be able to be used to detect other infectious diseases.

Two Faced 2D Material is a First at Rice – R & D Magazine

Rice materials scientists create flat sandwich of sulfur, molybdenum and selenium

Like a sandwich with wheat on the bottom and rye on the top, Rice University scientists have cooked up a tasty new twist on two-dimensional materials.

The Rice laboratory of materials scientistJun Louhas made a semiconductingtransition-metal dichalcogenide(TMD) that starts as a monolayer ofmolybdenum diselenide. They then strip the top layer of the lattice and replace precisely half the selenium atoms with sulfur.

The new material they callJanussulfur molybdenum selenium (SMoSe) has a crystalline construction the researchers said can host an intrinsic electric field and that also shows promise for catalytic production of hydrogen.

The work is detailed this month in the American Chemical Society journalACS Nano.

The two-faced material is technically two-dimensional, but like molybdenum diselenide it consists of three stacked layers of atoms arranged in a grid. From the top, they look like hexagonal rings a lagraphene, but from any other angle, the grid is more like a nanoscalejungle gym.

Tight control of the conditions in a typicalchemical vapor depositionfurnace 800 degrees Celsius (1,872 degrees Fahrenheit) at atmospheric pressure allowed the sulfur to interact with only the top layer of selenium atoms and leave the bottom untouched, the researchers said. If the temperature drifts above 850, all the selenium is replaced.

Like the intercalation of many other molecules demonstrated to have the ability to diffuse into the layered materials, diffusion of gaseous sulfur molecules in between the layers of theseVan der Waalscrystals, as well as the space between them and the substrates, requires sufficient driving force, said Rice postdoctoral researcher Jing Zhang, co-lead author of the paper with graduate student Shuai Jia. And the driving force in our experiments is controlled by the reaction temperature.

Close examination showed the presence of sulfur gave the material a larger band gap than molybdenum diselenide, the researchers said.

This type of two-faced structure has long been predicted theoretically but very rarely realized in the 2-D research community, Lou said. The break of symmetry in the out-of-plane direction of 2-D TMDs could lead to many applications, such as a basal-plane active 2-D catalyst, robust piezoelectricity-enabled sensors and actuators at the 2-D limit.

He said preparation of the Janus material should be universal to layered materials with similar structures. It will be quite interesting to look at the properties of the Janus configuration of other 2-D materials, Lou said.

Co-authors of the paper are graduate students Weibing Chen and Zehua Jin and postdoctoral researcher Hua Guo of Rice; research scientist Iskandar Kholmanov and professor Li Shi, the Myron L. Begeman Fellow in Engineering at the University of Texas at Austin; and graduate students Liang Dong and Dequan Er and Vivek Shenoy, a professor of materials science and engineering, of mechanical engineering and applied mechanics and of bioengineering at the University of Pennsylvania. Lou is a professor of materials science and nanoengineering.

The Air Force Office of Scientific Research, the Welch Foundation, the Army Research Office and the National Science Foundation supported the research.

System Bits: Aug. 15 – SemiEngineering

Machine-learning system for smoother streaming To combat the frustration of video buffering or pixelation, researchers at MITs Computer Science and Artificial Intelligence Laboratory (CSAIL) have developed Pensieve, an artificial intelligence system that uses machine learning to pick different algorithms depending on network conditions thereby delivering a higher-quality streaming experience with less rebuffering than existing systems.

Studies show that users abandon video sessions if the quality is too low, leading to major losses in ad revenue for content providers. Sites constantly have to be looking for new ways to innovate, according to MIT Professor Mohammad Alizadeh, whose team created Pensieve.

Sites like YouTube use adaptive bitrate (ABR) algorithms to try to give users a more consistent viewing experience. At the same time, it saves bandwidth: People usually dont watch videos all the way through, and so, with literally 1 billion hours of video streamed every day, it would be a big waste of resources to buffer thousands of long videos for all users at all times.

In experiments, Pensieve could stream video with 10 to 30 percent less rebuffering than other approaches, and at levels that users rated 10 to 25 percent higher on key quality of experience metrics. (Source: MIT CSAIL)

The researchers pointed out that while ABR algorithms have generally gotten the job done, viewer expectations for streaming video keep inflating, and often arent met when sites like Netflix and YouTube have to make imperfect trade-offs between things like the quality of the video versus how often it has to rebuffer.

The Pensieve AI system was found to be able to stream video with 10 to 30 percent less rebuffering than other approaches, and at levels that users rated 10 to 25 percent higher on key quality of experience (QoE) metrics.

Pensieve can also be customized based on a content providers priorities. For example, if a user on a subway is about to enter a dead zone, YouTube could turn down the bitrate so that it can load enough of the video that it wont have to rebuffer during the loss of network, the team said.

Mimicking human thought According to Purdue University researchers, a new computing technology called organismoids mimics some aspects of human thought by learning how to forget unimportant memories while retaining more vital ones.

Kaushik Roy, Purdue Universitys Edward G. Tiedemann Jr. Distinguished Professor of Electrical and Computer Engineering explained, The human brain is capable of continuous lifelong learning, and it does this partially by forgetting some information that is not critical. I learn slowly, but I keep forgetting other things along the way, so there is a graceful degradation in my accuracy of detecting things that are old. What we are trying to do is mimic that behavior of the brain to a certain extent, to create computers that not only learn new information but that also learn what to forget.

Central to the research is a ceramic quantum material called samarium nickelate, which was used to create devices called organismoids. The work was performed by researchers at Purdue, Rutgers University, MIT, Brookhaven National Laboratory and Argonne National Laboratory.

These devices possess certain characteristics of living beings and enable us to advance new learning algorithms that mimic some aspects of the human brain, Roy said. The results have far reaching implications for the fields of quantum materials as well as brain-inspired computing.

When exposed to hydrogen gas, the material undergoes a massive resistance change, as its crystal lattice is doped by hydrogen atoms. The material is said to breathe, expanding when hydrogen is added and contracting when the hydrogen is removed.

The main thing about the material is that when this breathes in hydrogen there is a spectacular quantum mechanical effect that allows the resistance to change by orders of magnitude. This is very unusual, and the effect is reversible because this dopant can be weakly attached to the lattice, so if you remove the hydrogen from the environment you can change the electrical resistance.

Organismoids might have applications in the emerging field of spintronics. Conventional computers use the presence and absence of an electric charge to represent ones and zeroes in a binary code needed to carry out computations. Spintronics, however, uses the spin state of electrons to represent ones and zeros, the team said. This could bring circuits that resemble biological neurons and synapses in a compact design not possible with CMOS circuits. Whereas it would take many CMOS devices to mimic a neuron or synapse, it might take only a single spintronic device. In future work, the researchers said they may demonstrate how to achieve habituation in an integrated circuit instead of exposing the material to hydrogen gas.

RNA nanodevices in living cells Synthetic biologists at the Wyss Institute at Harvard University are converting microbial cells into living devices that are able to perform useful tasks ranging from the production of drugs, fine chemicals and biofuels to detecting disease-causing agents and releasing therapeutic molecules inside the body.

To accomplish this, they said they fit cells with artificial molecular machinery that can sense stimuli such as toxins in the environment, metabolite levels or inflammatory signals. Much like electronic circuits, these synthetic biological circuits can process information and make logic-guided decisions. Unlike their electronic counterparts, however, biological circuits must be fabricated from the molecular components that cells can produce, and they must operate in the crowded and ever-changing environment within each cell.

So far, synthetic biological circuits can only sense a handful of signals, giving them an incomplete picture of conditions in the host cell. They are also built out of several moving parts in the form of different types of molecules, such as DNAs, RNAs, and proteins, that must find, bind and work together to sense and process signals. Identifying molecules that cooperate well with one another is difficult and makes development of new biological circuits a time-consuming and often unpredictable process.

The team at Wyss is now presenting an all-in-one solution that imbues a molecule of ribo nucleic acid or RNA with the capacity to sense multiple signals and make logical decisions to control protein production with high precision.

The studys approach resulted in a genetically encodable RNA nano-device that can perform an unprecedented 12-input logic operation to accurately regulate the expression of a fluorescent reporter protein in E. coli bacteria only when encountering a complex, user-prescribed profile of intra-cellular stimuli. Such programmable nano-devices may allow researchers to construct more sophisticated synthetic biological circuits, enabling them to analyze complex cellular environments efficiently and to respond accurately.

The teams approach evolved from its previous development of so-called Toehold Switches first published in 2014 which are programmable hairpin-like nano-structures made of RNA. In principle, RNA Toehold Switches can control the production of a specific protein: when a desired complementary trigger RNA, which can be part of the cells natural RNA repertoire, is present and binds to the toehold switch, the hairpin structure breaks open. Only then will the cells ribosomes get access to the RNA and produce the desired protein.

We wanted to take full advantage of the programmability of Toehold Switches and find a smart way to use them to expand the decision-making capabilities of living cells. Now with Ribocomputing Devices, we can couple protein production to specific combinations of many different input RNAs and only activate production when conditions allow it, said co-first and co-corresponding author Alexander Green, Ph.D. Green developed Toehold Switches with Yin and began the present study as a Postdoctoral Fellow in Yins team.
