NASA has gone a touch sartorial as it asks the public to vote on the design of its new prototype Z-2 spacesuit. Part of the Advanced Suit development program to come up with a replacement for the 22-year old suit designs currently used on the International Space Station, the Z-2 not only includes a number of technical innovations, but also a design that for the first time has an eye on the aesthetics of living and working in outer space.
In 2012, NASA showed off its Z-1 spacesuit prototype. The first new spacesuit developed by NASA in 20 years, it was named one of Time magazine's Best Inventions of that year. Its purpose wasnt just to replace an aging system, but to introduce a number of new ideas to make spacesuits a bit more efficient.
Spacesuits are anything but an inflatable set of coveralls and, with the exception of Sandra Bullock, they can't be put on or taken off in a few seconds. If anything, theyre less like long johns and more like mixed-gas deep diving rigs that require a lot of training and about an hour to put on after a long, boring period of breathing pure oxygen to avoid a nasty case of the bends. The Z-1 was designed to make spacewalks a bit easier.

Among a number of innovations, the Z-1 included a rear-entry hatch similar to those found on Russian spacesuits, but had the added advantage of allowing the suit to dock directly with a spacecraft. This not only made the suit easier to get in and out of, but because the spacecraft and suit were of the same pressure, there wasnt the need for a lengthy pre-breathing period. Then, of course, there was the aesthetic element that the Z-1 resembled Buzz Lightyears wardrobe, which caught the publics imagination.
The Z-2 prototype is the next step in the new spacesuit's evolution. Unlike the Z-1, which was made of soft fabrics and was more of a concept in many ways than a functioning system, the Z-2 will be the first spacesuit designed specifically for working on a planet surface to be tested in full vacuum. Tailored using 3D laser scans and incorporating 3D-printed components, its also the first rear-entry suit to use a hard upper torso, which makes it easier to wear, more durable, more impact resistant, and configurable to astronauts of different sizes. In addition, the joints have been redesigned based on tests of the Z-1 to make them more mobile, yet compatible with working in a hard vacuum.
According to NASA, the Z-2 will undergo a battery of extensive tests of its mobility, ability to work in a vacuum, comfort, with neutral buoyancy tests in a pool to simulate zero gravity and working on a simulated Martian landscape at the Johnson Space Center in Texas.
Another first for the Z-2 is that its not only being designed for looks as well as function, but the public is invited to vote on the design. The competing designs were produced in collaboration with ILC, the primary suit vendor, and Philadelphia University, and are for the outer shell of the suit, which protects it against chafing and snagging, as well as incorporating luminous elements to make it easy to see and identify in the dark. The space agency says that the three versions are aimed at showing off some aspects of the suits mobility.
Taking its cues from deep sea life, biomimicry has segmented pleats at the shoulder, elbow, hip and knee, and electroluminescent wire across the upper torso, which lights up as the ambient light dims like some sort of outer space jellyfish. The texture even has a scaly look like fish skin.
Technology, as the name implies, looks back to more conventional spacesuits, but with some sci-fi elements added, such as Luminex wire and light-emitting patches for crew identification. The Technology design has exposed rotating bearings, collapsing pleats for mobility and highlighted movement, and abrasion-resistant panels on the lower torso.

NASA's asteroid mission will test propulsion systems and other technologies that can ultimately establish a human presence on Mars, says NASAchief Charles Bolden.
NASA's wild plan to capture an asteroid and park it near the moon is only one step on the way to Mars, NASA chief Charles Bolden said Wednesday (March 26).

The space agency is planning an ambitious mission to send a robotic spacecraft to an asteroid, bag the space rock and bring it into orbit around the moon. While the asteroid-capture mission may sound like a huge task in its own right, Bolden thinks that it's only one leap toward a larger mission. The space agency should be focused on getting humans to Mars and establishing a presence on the Red Planet for years to come, Bolden said.
"The ultimate thing is to put boots on the ground on Mars, and that's not just to do a touch and go," Bolden said during a forum about the asteroid initiative Wednesday. "It's to live there one of these days." [NASA's Asteroid Capture Mission in Photos]
Though it might not be the ultimate goal, the asteroid redirect mission is still an important step that can be used to test propulsion systems and other technology that could help humans get to Mars. The asteroid mission may also be a good way to gather more information about the early solar system and develop asteroid mining techniques, advocates of the mission have said.
"We really make a big deal out of this [asteroid] initiative, but you should all understand, this is a tiny, tiny piece of getting humans to Mars," Bolden said. "I don't want anybody to lose focus on that. The ultimate goal of this agency right now when it comes to human spaceflight is to put humans on Mars. That's hard. That is really hard. We need a proving ground to develop some of the technologies and everything else."
That proving ground could be the asteroid capture mission. So far, NASA scientists have identified some promising asteroids that could potentially be captured and dragged into a stable orbit around the moon. NASA would launch a robotic mission to retrieve the chosen space rock and tow it into lunar orbit, where astronauts could visit and sample the asteroid by 2025.
Engineers are looking into two different ideas for how the retrieval mission would work. In one mission, the robotic spacecraft would visit a large asteroid and pluck a boulder off of it, bringing it back to lunar orbit. In the other, NASA would target a small asteroid that could be lassoed and deposited in a stable orbit. Scientists have now identified about six target asteroids for each of the missions.

Newswise Boston, MA Thousands of consumer products containing engineered nanoparticles microscopic particles found in everyday items from cosmetics and clothing to building materials enter the market every year. Concerns about possible environmental health and safety issues of these nano-enabled products continue to grow with scientists struggling to come up with fast, cheap, and easy-to-use cellular screening systems to determine possible hazards of vast libraries of engineered nanomaterials. However, determining how much exposure to engineered nanoparticles could be unsafe for humans requires precise knowledge of the amount (dose) of nanomaterials interacting with cells and tissues such as lungs and skin.
With chemicals, this is easy to do but when it comes to nanoparticles suspended in physiological media, this is not trivial. Engineered nanoparticles in biological media interact with serum proteins and form larger agglomerates which alter both their so called effective density and active surface area and ultimately define their delivery to cell dose and bio-interactions. This behavior has tremendous implications not only in measuring the exact amount of nanomaterials interacting with cells and tissue but also in defining hazard rankings of various engineered nanomaterials (ENMs). As a result, thousands of published cellular screening assays are difficult to interpret and use for risk assessment purposes.
Scientists at the Center for Nanotechnology and Nanotoxicology at Harvard School of Public Health (HSPH) have discovered a fast, simple, and inexpensive method to measure the effective density of engineered nanoparticles in physiological fluids, thereby making it possible to accurately determine the amount of nanomaterials that come into contact with cells and tissue in culture.
The method, referred to as the Volumetric Centrifugation Method (VCM), will be published in the March 28, 2014 Nature Communications.
The new discovery will have a major impact on the hazard assessment of engineered nanoparticles, enabling risk assessors to perform accurate hazard rankings of nanomaterials using cellular systems. Furthermore, by measuring the composition of nanomaterial agglomerates in physiologic fluids, it will allow scientists to design more effective nano-based drug delivery systems for nanomedicine applications.
The biggest challenge we have in assessing possible health effects associated with nano exposures is deciding when something is hazardous and when it is not, based on the dose level. At low levels, the risks are probably miniscule, said senior author Philip Demokritou, associate professor of aerosol physics in the Department of Environmental Health at HSPH. The question is: At what dose level does nano-exposure become problematic? The same question applies to nano-based drugs when we test their efficiency using cellular systems. How much of the administered nano-drug will come in contact with cells and tissue? This will determine the effective dose needed for a given cellular response, Demokritou said.
Federal regulatory agencies do not require manufacturers to test engineered nanoparticles, if the original form of the bulk material has already been shown to be safe. However, there is evidence that some of these materials could be more harmful in the nanoscale a scale at which materials may penetrate cells and bypass biological barriers more easily and exhibit unique physical, chemical, and biological properties compared to larger size particles. Nanotoxicologists are struggling to develop fast and cheap toxicological screening cellular assays to cope with the influx of vast forms of engineered nanomaterials and avoid laborious and expensive animal testing. However, this effort has been held back due to the lack of a simple-to-use, fast, method to measure the dose-response relationships and possible toxicological implications. While biological responses are fairly easy to measure, scientists are struggling to develop a fast method to assess the exact amount or dose of nanomaterials coming in contact with cells in biological media.
Dosimetric considerations are too complicated to consider in nano-bio assessments, but too important to ignore, Demokritou said. Comparisons of biological responses to nano-exposures usually rely on guesstimates based on properties measured in the dry powder form (e.g., mass, surface area, and density), without taking into account particle-particle and particle-fluid interactions in biological media. When suspended in fluids, nanoparticles typically form agglomerates that include large amounts of the suspending fluid, and that therefore have effective densities much lower than that of dry material. This greatly influences the particle delivery to cells, and reduces the surface area available for interactions with cells, said Glen DeLoid, research associate in the Department of Environmental Health, one of the two lead authors of the study. The VCM method will help nanobiologists and regulators to resolve conflicting in vitro cellular toxicity data that have been reported in the literature for various nanomaterials. These disparities likely result from lack of or inaccurate dosimetric considerations in nano-bio interactions in a cellular screening system, said Joel Cohen, doctoral student at HSPH and one of the two lead authors of the study.

Newswise Physicians have long suspected that chemotherapy can accelerate the aging process in patients treated for cancer. Using a test developed at UNC Lineberger Comprehensive Cancer Center to determine molecular aging, UNC oncologists have directly measured the impact of anti-cancer chemotherapy drugs on biological aging.
Researchers measured the level of p16, a protein that causes cellular aging, in the blood of 33 women over the age of 50 who had undergone chemotherapy for curable breast cancer. Samples were taken for analysis of molecular age from patients before chemotherapy, immediately following chemotherapy and a year after therapy finished. The analysis showed that curative chemotherapy also caused an increase in a patients molecular age that on average was equivalent to 15 years of normal aging. The same was true in a separate group of 176 breast cancer survivors who had received chemotherapy on average three and a half years prior.
The study, headed by Hanna Sanoff, MD, MPH, assistant professor with the UNC School of Medicine and member of UNC Lineberger, is published in this weeks Journal of the National Cancer Institute. Dr. Sanoff said that the results indicate that the p16 test holds promise as a means of evaluating how chemotherapy will affect a patients long-term health and survival and as a predictive biomarker for the long-term toxicity of chemotherapy.
Our theory is that if you have an advanced molecular age to begin with, it will be harder for you to tolerate chemotherapy, said Dr. Sanoff. We believe a high level of p16 before treatment could mean that a patient will have a harder time making new blood cells after each chemotherapy treatment, and therefore be at greater risk for anemia and infection during chemotherapy.
The key role of p16 in human aging has been established over the last decade in the lab of UNC Lineberger Director Dr. Norman Sharpless. Research conducted in Sharpless lab showed in 2004 that the levels of p16 increase exponentially with aging, and developed the p16 blood test for human use in 2009.
The next direction for this research, ongoing under the leadership of Dr. Hyman Muss, director of UNC Linebergers Geriatric Oncology Program, involves determining if markers of molecular age predict patients physical function and outcome in a number of clinical settings.
While these findings are highly provocative, we have much more to study and will have to verify in future trials how these changes in molecular aging affect long term survival, said Dr. Muss. Adjuvant chemotherapy has dramatically improved breast cancer survival and pending further data, the results of our study should not effect adjuvant chemotherapy decisions.
The p16 test seems particularly well-suited as an aging marker for this purpose as it plays a causal role in biological aging, is strongly correlated with chronological aging, and increases exponentially in response to pro-aging stimuli. Dr. Sanoff said she believes the test has promise as the basis of a clinical tool allowing physicians to evaluate the degree to which a given treatment accelerates biological and physical aging.
Excerpt from:
LAS VEGAS -- Footage of the sci-fi drama "Transcendence" previewed at CinemaCon in Las Vegas shows an eerily convincing Johnny Depp as a terminally ill scientist turned unruly machine in the Wally Pfister film that asks: What if we could upload a human mind into a computer?
Warner Bros. was the final studio to preview its upcoming titles at the theater exhibitor's convention Thursday, and it ended with an impressive crew of A-listers led by Depp.
The "Transcendence" clips were packed with explosions, sentimental moments between Depp (as Will) and leading lady Rebecca Hall (as Evelyn), and striking supporting performances by Kate Mara and Paul Bettany.
Morgan Freeman, Drew Barrymore, Adam Sandler, Clint Eastwood, Melissa McCarthy, Channing Tatum and Mila Kunis were among the other stars touting their upcoming projects.
Here, a peek at the plug-fest:
* "Jupiter Ascending," directed by Andy and Lana Wachowski (creators of "The Matrix" trilogy) and starring Channing Tatum and Mila Kunis. Set in the future, the sci-fi fantasy resembles "The Fifth Element" (Sans the delicious, campy wit, at least in the trailer). Tatum, sporting guy-liner and a set of super pointy ears, is still a believable hero and love interest for Kunis, who plays the unsuspecting queen of the universe. It's set for release in July.
* "Edge of Tomorrow," directed by Doug Liman and starring Tom Cruise and Emily Blunt. Based on Hiroshi Sakurazaka novel "All You Need is Kill," the sci-fi action epic sees Cruise and Blunt as soldiers dying repeatedly due to a time loop. Big-budget action films are customary for Cruise, but this is new highly physical territory for Blunt, whose character Rita Vrataski helps Cruise's Lt. Col. Bill Cage change his fate. It will hit theaters in June.
* "Godzilla," directed by Gareth Edwards and starring Bryan Cranston, Ken Watanabe and Elizabeth Olsen. On hand to introduce the extended trailer, Edwards said he'd just finished editing the film, which looks epic in scale with impressively grand special effects, on Wednesday. It's due May 16.
* "Blended," directed by Frank Coraci and starring Drew Barrymore and Adam Sandler. A very pregnant Barrymore, in a yellow dress, stepped on stage with Sandler and Coraci to promote their romantic comedy about two families who embark on a trip Africa. Due in May.
* "Tammy," directed by Ben Falcone and starring Melissa McCarthy, Susan Sarandon and Allison Janney. Married couple Falcone and McCarthy wrote what looks like a hilarious road trip comedy. McCarthy plays a woman who, after getting fired from her fast food gig and finding out her husband is cheating on her, hits the road with her lush of a grandmother (Sarandon). McCarthy and Falcone introduced the film, which McCarthy said took six years to finish. To be released in December.

Most ebook sellers try to lock you into a particular ecosystem. If you don't mind buying from the same company every time, this isn't too bad, but you lose the ability to comparison shop, as well as making it difficult to switch apps. Fortunately, there's a way around this problem.
In most other areas of life, we usually do comparison shopping for a better price. The trouble with ebook lock-in is that if your whole library is on the Kindle, you won't want to buy a book from another store. This is silly. We'll show you how to share books between libraries in a minute, but first you need books to start with!
Ebook search site Luzme is a handy tool for comparing book pricing among various stores. In addition to showing you prices for a given title across several services (including Kindle, Google Play, iTunes, Nook, Sony, and others), it also shows you how the price has changed over time so you can see if it's at a particular low point or if it it's likely to fluctuate at all.

Regardless of where you buy your ebooks, you probably want to be able to read all of your books in a single place.The best way to do this is to move all of your books into one service. While none of the major bookstores offer a direct way to port your library to their competitors, it's possible to convert and upload them to most.
If you decide to follow this guide for all of your books, you should probably choose a target service based on which app you enjoy reading with the most (you know, the way it should be). However, it's harder to upload outside books to some services than others. For example, it's technically possible to read Epub books on a Kindle, but it's a little convoluted and might require manually moving files every time. For this guide, we'll use Google Play Books as our target because, once the conversion process is completed, you can upload an Epub to your library once and it will immediately be available on all your devices.
S
The first step to consolidating your library is to convert your ebooks to the proper format. For this guide, we'll convert to Epub since it's the most versatile format, but the app we're going to use supports converting between a variety of formats, so you can strip the DRM and add it to just about any device you want. For this example, we'll show you how to convert Kindle books. This guide builds on our previous guide on how to strip DRM from your ebooks. If you don't care about converting your books, you can check out that guide for simplified instructions.
