  • Interviews: Ask the Hampton Creek Team About the Science and Future of Food

    samzenpus writes Hampton Creek is a food technology company that makes food healthier by utilizing a specially made egg substitute in food products. The company was selected by Bill Gates to be featured on his website in a story called, The Future of Food, and has raised $30 million in funding. Hampton Creek's latest product is called, Just Cookies, which is an eggless chocolate chip cookie dough, but it is their eggless mayo that has been in the news lately. Unilever, which manufactures Hellmann's and Best Foods mayonnaise, is suing Hampton Creek claiming that the name Just Mayo is misleading to consumers. Named one of Entrepreneur Magazine's 100 Brilliant Companies and one of CNBC's Top 50 Disruptors, Hampton Creek has picked up some impressive talent including the former lead data scientist at Google Maps, Dan Zigmond. With Thanksgiving just around the corner, Dan and the Hampton Creek team have agreed to answer any questions you may have. As usual, ask as many as you'd like, but please, one per post.

  • NASA Offering Contracts To Encourage Asteroid Mining

    An anonymous reader writes "Two private companies, Deep Space Industries and Planetary Resources, have received contracts from NASA to study asteroid redirection and will pursue their plans of asteroid mining. From the article: "Deep Space Industries is planning to build a number of dense spacecrafts called FireFlies, and they plan on sending the satellites on one way missions to gather information about the density, shape, composition and size of an asteroid. They also have plans to build a spacecraft called Dragonfly, which has the purpose of catching asteroids. The asteroid material will be collected and returned to Earth by 'Harvesters'. Planetary Resources, on the other hand, plans to build a number of middle sized and small telescopes that will be capable of examining asteroids near the planet Earth for economic potential. They already have the telescopes Arkyd 300, Arkyd 200 and the Arkyd 100, each having its own specific systems."

  • Apple To Donate Profit Portion From Black Friday For AIDS Fight

    An anonymous reader writes Apple will donate a portion of their sales from online and retail stores on Cyber Monday and Black Friday as a contribution to the worldwide fight against AIDS. Apple kicks off a two-week fundraising campaign for RED, the charity started by U2 lead singer Bono and Bobby Shriver. It includes 25 partnering app-makers, from Angry Birds to Toca Boca, which will donate all proceeds from purchases of their apps or in-app upgrades. In a statement, Apple CEO Tim Cook said: "Apple is a proud supporter of (RED) because we believe the gift of life is the most important gift anyone can give. For eight years, our customers have been helping fight AIDS in Africa by funding life-saving treatments which are having a profoundly positive impact. This year we are launching our biggest fundraising push yet with the participation of Apple's retail and online stores, and some of the brightest minds in the App Store are lending their talents to the effort as well."

  • Multi-National Crew Reaches Space Station

    An anonymous reader writes A Russian capsule carrying three astronauts from Russia, the United States and Italy has blasted off for the International Space Station. Aboard the capsule are Russian Anton Shkaplerov, Nasa's Terry Virts and European Space Agency astronaut Samantha Cristoforetti, Italy's first female astronaut. "I think that 100 years from now, 500 years from now, people will look back on this as the initial baby steps that we took going into the solar system," Virts told a pre-launch press conference. "In the same way that we look back on Columbus and the other explorers 500 years ago, this is the way people will look at this time in history."

  • Study: Space Rock Impacts Not Random

    sciencehabit writes When it comes to small space rocks blowing up in Earth's atmosphere, not all days are created equal. Scientists have found that, contrary to what they thought, such events are not random, and these explosions may occur more frequently on certain days. Rather than random occurrences, many large airbursts might result from collisions between Earth and streams of debris associated with small asteroids or comets. The new findings may help astronomers narrow their search for objects in orbits that threaten Earth, the researchers suggest.

  • How the World's Agricultural Boom Has Changed CO2 Cycles

    An anonymous reader writes Every year levels of carbon dioxide drop in the summer as plants "inhale," and climb again as they exhale after the growing season in the Northern Hemisphere. However, the last 50 years has seen the size of this swing has increase by as much as 50%, for reasons that aren't fully understood. A team of researchers may have the answer. They have shown that agricultural production, corn in particular, may generate up to 25% of the increase in this seasonal carbon cycle. "This study shows the power of modeling and data mining in addressing potential sources contributing to seasonal changes in carbon dioxide" program director for the National Science Foundation's Macro Systems Biology Program, who supported the research, Liz Blood says. "It points to the role of basic research in finding answers to complex problems."

  • NASA Remasters 20-Year-Old Galileo Photographs of Jupiter's Moon, Europa

    An anonymous reader writes with news that NASA has released remastered pictures of Europa taken by the Galileo spacecraft. "Scientists have produced a new version of what is perhaps NASA's best view of Jupiter's ice-covered moon, Europa. The mosaic of color images was obtained in the late 1990s by NASA's Galileo spacecraft. This is the first time that NASA is publishing a version of the scene produced using modern image processing techniques. This view of Europa stands out as the color view that shows the largest portion of the moon's surface at the highest resolution. An earlier, lower-resolution version of the view, published in 2001, featured colors that had been strongly enhanced. The new image more closely approximates what the human eye would see. Space imaging enthusiasts have produced their own versions of the view using the publicly available data, but NASA has not previously issued its own rendition using near-natural color."

  • Elon Musk Talks "X-Wing" Fins For Reusable Rockets, Seafaring Spaceport Drones

    An anonymous reader writes Elon Musk sent a number of tweets recently in which he detailed a program to test the function of "X-Wing" style grid fins that could help spacecraft navigate upon re-entry. The tweets describing how it would work, also include an autonomous seafaring platform, which can hold its position within three meters even in a heavy storm, that would act as a landing pad. From the article: "The SpaceX reusable rocket program has been progressing with varying results, including an explosion over Texas back in August. While the incident didn't result in any injury or even 'near injuries,' Musk conceded in a tweet that this was evidence that '[r]ockets are tricky.' An earlier test flight from this summer involving an ocean splashdown was considered more successful, proving that the Space X Falcon 9 booster could re-enter earth's atmosphere, restart its engines, deploy its landing legs and make a touch down at 'near zero velocity.'"

  • Prospects Rise For a 2015 UN Climate Deal, But Likely To Be Weak

    An anonymous reader writes with news that a global climate deal seems to be on the horizon. "A global deal to combat climate change in 2015 looks more likely after promises for action by China, the United States and the European Union, but any agreement will probably be too weak to halt rising temperatures. Delegates from almost 200 nations will meet in Lima, Peru, from Dec. 1-12 to work on the accord due in Paris in a year's time, also spurred by new scientific warnings about risks of floods, heatwaves, ocean acidification and rising seas. After failure to agree a sweeping U.N. treaty at a summit in Copenhagen in 2009, the easier but less ambitious aim now is a deal made up of 'nationally determined' plans to help reverse a 45 percent rise in greenhouse gas emissions since 1990."

  • Spaceport America Loses $1.7 Million Due To Virgin Galactic Delays

    An anonymous reader writes "Officials of New Mexico's Spaceport Authority were grilled by lawmakers about the now vacant Spaceport America following the deadly crash of Virgin Galactic's SpaceShipTwo. The spaceport was built as a hub for commercial space flights. Its immediate future is uncertain since Virgin Galactic has indefinitely pushed back the launch date of its space tourism flights. From the article: "Christine Anderson, the authority's executive director, learned last week that she might have to do so one legislator at a time. Anderson was called out by Rep. Patricia Lundstrom, D-Gallup, for handing members of an interim legislative finance committee a presentation filled mostly with photographs. Lundstrom and other lawmakers wanted hard numbers and more details about what plan the authority has to get past the Virgin Galactic mishap and get the taxpayer-financed spaceport off the ground. 'It just made all of us look like idiots, like we don't do our homework,' Anderson said. 'That's not the case whatsoever.'"

  • Doubling Saturated Fat In Diet Does Not Increase It In Blood

    An anonymous reader writes: A new study by researchers at Ohio State University found that dramatically increasing the amount of saturated fat in a person's diet did not increase the amount of saturated fat found in their blood. Professor Jeff Volek, the study's senior author, said it "challenges the conventional wisdom that has demonized saturated fat and extends our knowledge of why dietary saturated fat doesn't correlate with disease."

    The study also showed that increasing carbohydrates in the diet led to an increase in a particular fatty acid previous studies have linked to heart disease. Volek continued, "People believe 'you are what you eat,' but in reality, you are what you save from what you eat. The point is you don't necessarily save the saturated fat that you eat. And the primary regulator of what you save in terms of fat is the carbohydrate in your diet. Since more than half of Americans show some signs of carb intolerance, it makes more sense to focus on carb restriction than fat restriction."

  • Profanity-Laced Academic Paper Exposes Scam Journal

    Frosty P writes: A scientific paper titled "Get Me Off Your F****** Mailing List" was actually accepted by the International Journal of Advanced Computer Technology. As reported at Vox and other web sites, the journal, despite its distinguished name, is a predatory open-access journal. These sorts of low-quality journals spam thousands of scientists, offering to publish their work for a fee. In 2005, computer scientists David Mazières and Eddie Kohler created this highly profane ten-page paper as a joke, to send in replying to unwanted conference invitations. It literally just contains that seven-word phrase over and over, along with a nice flow chart and scatter-plot graph. More recently, computer scientist Peter Vamplew sent it to the IJACT in response to spam from the journal, and the paper was automatically accepted with an anonymous reviewer rating it as "excellent," and requested a fee of $150. Over the years, the number of these predatory journals has exploded. Jeffrey Beall, a librarian at the University of Colorado, keeps an up-to-date list of them to help researchers avoid being taken in; it currently has 550 publishers and journals on it."

  • Extreme Shrimp May Hold Clues To Alien Life On Europa

    HughPickens.com writes: Scientists at NASA's Jet Propulsion Laboratory are studying a mysterious ecosystem at one of the world's deepest undersea hydrothermal vents to get clues about what life could be like on other planetary bodies, such as Jupiter's icy moon Europa, which has a subsurface ocean. At the vents, tiny shrimp are piled on top of each other, layer upon layer, crawling on rock chimneys that spew hot water. "You go along the ocean bottom and there's nothing, effectively," says Max Coleman. "And then suddenly we get these hydrothermal vents and a massive ecosystem. It's just literally teeming with life." Bacteria, inside the shrimps' mouths and in specially evolved gill covers, produce organic matter that feed the crustaceans. The particular bacteria in the vents are able to survive in extreme environments because of chemosynthesis, a process that works in the absence of sunlight and involves organisms getting energy from chemical reactions. In this case, the bacteria use hydrogen sulfide, a chemical abundant at the vents, to make organic matter. The temperatures at the vents can climb up to a scorching 842 degrees Fahrenheit (450 degrees Celsius), but waters just an inch away are cool enough to support the shrimp. The shrimp are blind, but have thermal receptors in the backs of their heads.

    According to the exobiologists, these mysterious shrimps and its symbiotic bacterium may hold clues "about what life could be like on other planetary bodies." It's life that may be similar—at the basic level—to what could be lurking in the oceans of Europa, deep under the icy crust of the Jupiter moon. According to Emma Versteegh "whether an animal like this could exist on Europa heavily depends on the actual amount of energy that's released there, through hydrothermal vents." Nobody is seriously planning a landing mission on Europa yet. But the European Space Agency aims to launch its JUpiter ICy moons Explorer mission (JUICE) to make the first thickness measurements of Europa's icy crust starting in 2030 and NASA also has begun planning a Europa Clipper mission that would study the icy moon while doing flybys in a Jupiter orbit.

  • Molecular Clusters That Can Retain Charge Could Revolutionize Computer Memory

    jfruh writes:Computing devices have been gobbling up more and more memory, but storage tech has been hitting its limits, creating a bottleneck. Now researchers in Spain and Scotland have reported a breakthrough in working with metal-oxide clusters that can retain their charge. These molecules could serve as the basis for RAM and flash memory that will be leagues smaller than existing components (abstract).

  • CERN Releases LHC Data

    An anonymous reader writes: Ever wished you had access to CERN's LHC data to help with your backyard high-energy physics research? Today you're in luck. CERN has launched its Open Data Portal, which makes experimental data produced by the Large Hadron Collider open to the public. "The first high-level and analyzable collision data openly released come from the CMS experiment and were originally collected in 2010 during the first LHC run. This data set is now publicly available on the CERN Open Data Portal. Open source software to read and analyze the data is also available, together with the corresponding documentation. The CMS collaboration is committed to releasing its data three years after collection, after they have been thoroughly studied by the collaboration." You can read more about CERN's commitment to "Open Science" here.

  • Harvard Scientists Say It's Time To Start Thinking About Engineering the Climate

    merbs writes: Harvard has long been home to one of the fiercest advocates for climate engineering. This week, Harvard's School of Engineering and Applied Sciences published a research announcement headlined "Adjusting Earth's Thermostat, With Caution." That might read as oxymoronic — intentionally altering the planet's climate has rarely been considered a cautious enterprise — but it fairly accurately reflects the thrust of several new studies published by the Royal Society, all focused on exploring the controversial field of geoengineering.

  • Culberson As Chair of NASA Fundng Subcommittee Makes Europa Mission More Likely

    MarkWhittington writes: As many have expected, Rep. John Culberson (R-TX) has been elevated to chair the House Appropriations Subcommittee for Commerce, Justice, and Science. The subcommittee has charge of NASA funding, something of keen interest for the congressman, whose Houston district is close to the Johnson Spaceflight Center. Moreover, Culberson's enthusiasm for space exploration goes far beyond what would be expected from a Texas representative.

    Culberson is a champion of a mission to Europa, a moon of Jupiter. Europa is an ice-covered moon that is thought to conceal an ocean of water, warmed by tidal forces, which might contain life. Using the heavy-lift Space Launch System, NASA could launch a large-scale probe to study Europa and ascertain whether it harbors alien life or not. Culberson's elevation makes such a mission far more likely to occur.

  • CMI Director Alex King Talks About Rare Earth Supplies (Video 2)

    Yesterday we ran video #1 of 2 about the Critical Materials Institute (CMI) at the Iowa State Ames Laboratory in Ames, Iowa. They have partners from other national laboratories, universities, and industry, too. Obviously there is more than enough information on this subject that Dr. King can easily fill two 15-minute videos, not to mention so many Google links that instead of trying to list all of them, we're giving you one link to Google using the search term "rare earths." Yes, we know Rare Earth would be a great name for a rock band. But the mineral rare earths are important in the manufacture of items ranging from strong magnets to touch screens and rechargeable batteries, so please watch the video(s) or at least read the transcript(s).

  • People Trained To Experience an Overlap In Senses Also Receive IQ Boost

    Zothecula writes Tasting lemons when they see a number seven, regarding a certain letter as being yellow in color. Not a great deal is known about why some people experience an overlapping of the senses, a phenomena known as synesthesia. But a new study conducted at the University of Sussex has suggested that specific training of the mind can induce the effects of the condition. The study even suggests that such training can boost a person's IQ.

  • Millions of Spiders Seen In Mass Dispersal Event In Nova Scotia

    Freshly Exhumed writes A bizarre and oddly beautiful display of spider webs have been woven across a large field along a walking trail in Cape Breton, Nova Scotia, Canada. "Well it's acres and acres; it's a sea of web," said Allen McCormick. Prof. Rob Bennett, an expert on spiders who works at the Royal British Columbia Museum in Victoria, BC, Canada, said tiny, sheet-web weaver spiders known as Erigoninae linyphiidae most likely left the webs. Bennett said the spiders cast a web net to catch the wind and float away in a process known as ballooning. The webs in the field are the spiders' drag lines, left behind as they climb to the top of long grass to be whisked away by the wind. Bennett said it's a mystery why these spiders take off en masse.
