		<description><![CDATA[In Star Trek: The Next Generation, we were introduced to food replicators: devices capable of fiddling with reality at the subatomic level to reproduce everything edible, from steaks to snacks to steaming cups of tea. In reality, such fanciful devices &#8212; based on the show&#8217;s equally far-fetched transporter technology &#8212; probably couldn&#8217;t exist, but that doesn&#8217;t mean something like 3D food printing might not (eventually) get the job done just as effectively. (MORE: Why Argentine Steaks Are Getting Harder to Find) We may need food-printing technology relatively soon. Several multibillion-dollar mission-to-Mars projects are in the works, including Mars One, to which some 78,000 people recently applied. The estimated arrival date of the first colonists on that mission is 2023, barely a decade from now. Imagine having to plan that menu; the trip alone could take seven months, after which you&#8217;re essentially stuck on the planet indefinitely, subsisting on what you brought along or supplies fired planet-to-planet like some sort of deep-space feeding tube. We may have the beginnings of an answer to the question soon: NASA just threw a $125,000, six-month grant at a project by Anjan Contractor, a mechanical engineer at Systems and Materials Research Corporation in Austin to develop a working prototype of his proposed universal food synthesizer. &#8220;Long distance space travel requires 15-plus years of shelf life,&#8221; Contractor told Quartz. &#8220;The way we are working on it is, all the carbs, proteins and macro and micro nutrients are in powder form. We take moisture out, and in that form it will last maybe 30 years.&#8221; But step back from all the sexy space mission talk and you realize there may be a much more vital application for the technology right here on Earth: placing 3D food printers in households, allowing a world population that&#8217;s on its way to an estimated nine billion people by 2040 to synthesize healthy meals from powder-filled cartridges with &#8212; since they&#8217;ve been leeched of moisture, sort of like freeze-dried astronaut ice cream &#8212; incredible shelf lives. Quartz notes that &#8220;since a powder is a<img alt="" border="0" src="http://stats.wordpress.com/b.gif?host=newsfeed.time.com&#038;blog=12783068&#038;post=209432&#038;subd=timenewsfeed&#038;ref=&#038;feed=1" width="1" height="1" />]]></description>

		<description><![CDATA[Scientists in Canada believe they have just identified the oldest dome-headed dinosaur of its kind. After three specimens of a small, dog-sized dinosaur turned up near a provincial park in Alberta, Canada, a team of researchers investigated the fossils — only to find out they dated back at least 85 million years. The species, Acrotholus audeti, was an 85-pound, thick-skulled dinosaur. In fact, its skull was more than two inches thick according to a recently published article in the scientific Nature Communications journal. (MORE: Australian Mogul Wants to Open Giant Dinosaur Park in Australia) The bones were found on a farm belonging to resident Roy Audet, and as a result, the species was partially named after the Canadian. Bone-headed dinosaurs, or thick-headed lizards, are often known as pachycephalosaurs in the scientific community. David Evans, who led the expedition and is a curator at the Royal Ontario Museum, remarked on his findings to the BBC. “What’s interesting about Acrotholus is that it&#8217;s the oldest known pachycephalosaur from North America, and it might be the oldest known pachycephalosaur in the world.” According to the Huffington Post, the fossils are about 5 million years older than the next known pachycephalosaur specimen found on the continent. Another pachycephalosaur was discovered in Mongolia, but it&#8217;s unclear which fossil is older. So why is this find so remarkable in comparison to discoveries of its large and terrifying brethren? Huffington Post reports: Given the diversity of small animals in modern times, researchers would expect to see that ancient ecosystems had a large share of tiny dinosaurs. But dinosaurs that weighed less than about 220 lbs. (100 kilograms) don&#8217;t fossilize well. Any bones that weren&#8217;t immediately scattered or weathered into dust were often washed away from the death site, leading to jumbled, confused fossil sites. Big beasts such as long-necked, bus-sized sauropods are easier to unearth. (MORE: Scientists Discover the Oldest Dinosaur Yet) Evans and his colleagues found that pachycephalosaur diversity in the scientific community was significantly underestimated. &#8220;What Acrotholus does is it extends our knowledge of the anatomy<img alt="" border="0" src="http://stats.wordpress.com/b.gif?host=newsfeed.time.com&#038;blog=12783068&#038;post=207152&#038;subd=timenewsfeed&#038;ref=&#038;feed=1" width="1" height="1" />]]></description>

		<description><![CDATA[Three biotechnology entrepreneurs have come up with a bright idea that has attracted a wealth of interest and backing on the crowdfunding website Kickstarter, which allows people to donate money directly to projects they want to help finance. The brainchild of synthetic biologist Omri Amirav-Drory, plant scientist Kyle Taylor and project leader Antony Evans, the Glowing Plants initiative aims to create a glow-in-the-dark plant using synthetic biology techniques that could possibly replace traditional lighting — with the tantalizing prospect of one day creating glow-in-the-dark trees to replace street lights. (MORE: The Risks and Rewards of Synthetic Biology) Their pitch seems to have resonated well with funders: with less than a month to go before it reaches its final funding date on Kickstarter, nearly 5000 backers have contributed some $280,000 – far surpassing the initial $65,000 goal. Admittedly, the techniques used to realize their idea are not original: The first bioluminescent plant was developed in 1986. In 2003, a Taiwanese scientist developed a way to make otherwise colorless rice fish appear neon green using a protein from jellyfish. In the promotional video on its Kickstarter page, Evans explains that they are using “off the shelf methods to create real glowing plants in a do-it-yourself biolab in California.” Specifically, the Glowing Plants team will use the fluorescent gene found in fireflies, then compile its DNA sequence using a DNA-writing software called Genome Compiler. Once the money from the Kickstarter campaign is used to print the DNA, Evans and his colleagues will transplant the sequence into their prototype plant, the small weed Arabidopsis thaliana, using a bacteria that can insert its DNA into the cell nucleus of the plants flowers. This, in turn, will enable future plants grown from the genetically modified plant&#8217;s seeds to glow. (MORE: The First Book To Be Encoded in DNA) Although it has been a run-away success on Kickstarter, the project is not without its snags and doubters. Theo Sanderson, a scientist on the University of Cambridge team that created bioluminescent bacteria in 2010, expressed concerns about the new project<img alt="" border="0" src="http://stats.wordpress.com/b.gif?host=newsfeed.time.com&#038;blog=12783068&#038;post=207103&#038;subd=timenewsfeed&#038;ref=&#038;feed=1" width="1" height="1" />]]></description>

		<description><![CDATA[Charles Darwin kept his theory of evolution to himself for 21 years. Now the single largest publication of Darwin’s personal letters are available online, thanks to efforts by the Cambridge University Library, which holds the largest Darwin archive, including annotated books from his working library and notes from his voyage on the HMS Beagle. The project will begin with what scholars consider the most important correspondences – some 1,200 letters – with his confidant, the botanist Joseph Hooker, according to The Independent. It seems Hooker not only supplied Darwin with exotic plant species&#8211;but also provided moral support, as both men suffered multiple family tragedies. (MORE: Charles Darwin Garnered 4,000 Votes in a Georgia County) While Darwin was a scientist once slandered by his fellow Victorians for proposing that animals and man share a common ancestor, the letters &#8221;give a different picture of both Darwin and the scientific enterprise, in showing it as intensely collaborative, and that it is not divorced from private life,&#8221; Paul White, editor and research associate of the project, said in an interview with BBC&#8217;s Newshour. One of the most touching letters that humanizes Darwin is about losing his daughter-in-law, who had collected plant specimens for him during her own honeymoon. As Darwin wrote to Hooker in a letter that has already been published: “I am sure you will pity us, when you hear that Amy… was seized with convulsion which lasted for several hours, she then sunk into a stupor and I saw her expire at 7 o’clock this morning…I cannot think what will become of Frank. She helped &#38; encouraged him in his scientific work &#38; whether he will ever have heart to go on again or what he will do I cannot conceive.&#8221; Other correspondences that are available now for viewing include the most famous one, in which Darwin confesses his initial feelings about his then developing theory: &#8220;I am almost convinced (quite contrary to opinion I started with) that species are not (it is like confessing a murder) immutable,&#8221; he writes. In fact, after Darwin&#8217;s infant son died of scarlet fever, he almost gave up his claim on the natural selection theory<img alt="" border="0" src="http://stats.wordpress.com/b.gif?host=newsfeed.time.com&#038;blog=12783068&#038;post=201092&#038;subd=timenewsfeed&#038;ref=&#038;feed=1" width="1" height="1" />]]></description>

		<description><![CDATA[Rejoice, Harry Potter fans! Scientists have invented a miniature version of the boy wizard&#8217;s invisibility cloak, though so far it works only in microwave light, not visible light, reported CBS NEWS. In a study recently published in the New Journal of Physics, developers say their “3-D stand-alone mantle cloak,” the first ultra-thin invisibility cloak ever invented, is one step closer to a real invisibility cloak that can hide a Harry Potter or anyone else in broad daylight. (More: A Harry Potter-Style Invisibility Cloak: Possible, Says Science) In lab tests,  scientists at the University of Texas, Austin, wrapped an 18-centimeter long cylindrical rod under their cloak and successfully made it disappear when they beamed microwaves at the object. According to NBC News, the researchers made the garment from a metascreen, a super-thin material created from strips of copper attached to a flexible polycarbonate film. The copper strips are only 66-micrometers thick, while the polycarbonate film is 100-micrometers thick. Scientists also used a new technique called mantle cloaking, which cancels out light waves that bounce off the shielded object to achieve an overall effect of transparency and “invisibility at all angles of observation,” study co-author Andrea Alu told CBS NEWS. This is not the first time that scientists have built something that can make objects vanish. In 2011, researcher Shuang Zhang at the University of Birmingham developed a cloak from a lump of crystal that can make small objects seem to disappear. In the same year, rsearcher Ali Aliev at the University of Texas, Dallas exploited the mirage effect and made threads of an invisibility cloak from carbon nanotubes.

		<description><![CDATA[James Cameron, the director who gave us critically-acclaimed films like The Terminator, Titanic, Avatar, is giving us the craft that he built and rode into the sea’s deepest spot last year – well not us per se, but to the Woods Hole Oceanographic Institution (WHOI), according to the New York Times. The director-explorer’s donation to WHOI is part of a new collaboration meant to speed ocean exploration, the partners announced this week. The undersea craft, which cost Cameron roughly $10 million out of pocket and is known as “Deepsea Challenger,” will be used mainly to aid the design of advanced technologies, rather than to routinely carry scientists into the sea’s depths, the Times reported.  However, scientists at the institution are already planning to use the cameras and lighting systems on the craft on the upcoming dive by the remotely controlled vehicle Nereus, which will return to trenches in the Atlantic and the Pacific over the next two years. (MORE: James Cameron Reaches Ocean’s Deepest Point, 7 Miles Below) The announcement comes around the one-year anniversary of the director’s solo dive through the waters of the western Pacific.  Cameron traveled down nearly 7 miles in his torpedo-like vehicle, resting at the bottom of the Challenger Deep – the lowest point of the Mariana Trench, which, according to the New York Times, is the deepest of many seabed alcoves that can be found around the globe.  At the time, the director’s expedition, a partnership with National Geographic and Rolex, was highly publicized. In fact, Cameron’s expedition is now being turned into a 3D film. The Deepsea Challenger is the only vehicle that can carry people down so deep in the water, and ocean engineers have praised the craft, which was designed by the Hollywood director and a team in Australia.  It took the team seven years to create the craft’s materials and photographic systems. Cameron told the New York Times that the main goal of his new partnership with WHOI “is to get the technology out there, to capitalize on the engineering advances on the highest possible degree.” Along<img alt="" border="0" src="http://stats.wordpress.com/b.gif?host=newsfeed.time.com&#038;blog=12783068&#038;post=201611&#038;subd=timenewsfeed&#038;ref=&#038;feed=1" width="1" height="1" />]]></description>

		<description><![CDATA[Correction Appended: Mar. 20, 2013 The Turducken — a duck stuffed inside a chicken stuffed inside a turkey — is a mythical culinary beast and the dream entree of Thanksgiving obsessives everywhere. And now, science is on its way towards making the Turducken a reality — sort of: a duck has successfully fathered a chicken at the Central Veterinary Research Laboratory in Dubai. (MORE: Alternative Thanksgiving Recipes from the World&#8217;s Top Chefs) Researchers injected a chicken&#8217;s germ cells — carrying DNA to produce eggs and sperm — into the reproductive organs of a male duck embryo; once the duck matured, it began to produce the chicken&#8217;s sperm. Initially looking to genetically modify chicken to produce more fertile hens (the global poultry industry currently maintains some 50 billion chickens), these scientists are now planning to use this technique to allow hens to lay eggs of other birds, including ducks, songbirds, hawks or eagles. The ultimate goal is to &#8221;use this system to propagate endangered species or potentially bring back an extinct one,” according to a recent TEDx talk by Mike McGrew, a scientist at the Roslin Institute who collaborates extensively with the Dubai team. Roslin Institute researchers have also created genetically modified chickens that prevent the spread of bird flu and — most notably — Dolly the sheep, the world’s first cloned mammal. (MORE: Scientists Clone Extinct Frog that Upchucks Its Own Young) The original version of this article and its headline incorrectly stated that British researchers have successfully made a duck inside a chicken. Scientists in Dubai are conducting this project, and a duck has fathered a chicken. <img alt="" border="0" src="http://stats.wordpress.com/b.gif?host=newsfeed.time.com&#038;blog=12783068&#038;post=200240&#038;subd=timenewsfeed&#038;ref=&#038;feed=1" width="1" height="1" />]]></description>

		<description><![CDATA[Alas, it still won&#8217;t give us feisty dinosaurs from the Triassic, but scientists have managed to use a cloning technique to resurrect an extinct frog that gives birth by upchucking its little ones. (WATCH: Coffee-Powered Car Breaks World Record) No really, this type of frog incubates its eggs in its stomach — a technique known as&#8221;gastric-brooding&#8221; — sort of like the gut-dwelling monstrosities in the Alien films. Except its completely non-sinister babies don&#8217;t come tearing out of their mother&#8217;s stomachs, they simply make their way up the gullet and out of the mouth. The eggs are coated in an acid-inhibiting substance, which allows the embryos to do their thing undisturbed. And yet by 1983, gastric-brooding frogs had become extinct for reasons no one&#8217;s entirely clear on (scientists suspect various non-human causes, including habitat loss, parasites and a type of fungal infection). How do you bring an odd-sounding creature like this back? With somatic-cell nuclear transfer cloning, of course. Popular Science explains that scientists at the University of Newscastle in Australia (the frogs had been native to the eastern part of the country) took a related frog, neutralized its eggs, then swapped them for eggs extracted from a gastric-brooding frog, harvested decades ago and cryo-preserved in a conventional freezer. Somatic-cell nuclear transfer, whereby an inert cell nucleus is implanted into a fresh egg, allowed the eggs to begin dividing and the process took wing from there. What do you call a quest to resurrect a species that would otherwise have been lost forever? Amazing, of course, but also the &#8220;Lazarus Project&#8221; &#8212; what else?

		<description><![CDATA[Russia wasn&#8217;t the only country rattled by the meteor that exploded over Chelyabinsk on Feb. 15. According to the Comprehensive Test Ban Treaty Organization (CTBTO), the blast produced the largest low-frequency sound wave ever picked up by its nuclear test monitoring system. The 32-second-long sound wave traveled as far as Antarctica and Greenland, boasting 450-500 kilotons of energy — making it about as powerful as 30 nuclear bombs. People cannot hear them, however, according to the CTBTO. &#8220;It’s not a single explosion, it’s burning, traveling faster than the speed of sound,&#8221; the international agency said in a news release. &#8220;That’s how we distinguish it from mining blasts or volcanic eruptions.&#8221; (WATCH: Meteorites Crash in Russia) Margaret Campbell-Brown, astronomer at the University of Western Ontario in Canada, told CNN that the size of the wave is helping scientists determine how big the meteor was. Then they&#8217;ll be able measure the flaming space rock using &#8221;an estimate of the meteor&#8217;s speed from the numerous dashboard and mobile-phone cameras that captured the scene.&#8221; Current estimates say the Russian meteor had a width of 56 feet, weighed 7,000 tons and was traveling at 40,000 mph, according to CNN. Brown told CNN, &#8220;In terms of [meteors] we have observed, this is the largest since Tunguska&#8221; — the object that exploded over a remote Siberian forest in 1908, annihilating 80 million trees across some 830 square miles. More than 1,500 people were injured by wayward glass shards when the Chelyabinsk meteor broke up in mid-air earlier this month.

		<description><![CDATA[Bigfoot exists and there is DNA to prove it, or at least that’s what one scientific journal is claiming, according to the Huffington Post U.K. The study, published in the DeNovo Scientific Journal is a culmination of lead researcher Melba Ketchum’s five years studyingalleged samples of the Sasquatch’s hair, blood, saliva and urine. However, the legitimacy of the scientific journal that published the Sasquatch Genome Project is being questioned: Ketchum, a Texas researcher and former veterinarian, purchased the publication after her study, titled “Novel North American Hominins: Next Generation Sequencing of Three Whole Genomes and Associated Studies,” had been rejected by other journals.  “Rather than spend another five years just trying to find a journal to publish and hoping that decent, open minded reviewers would be chosen, we acquired the rights to this journal and renamed it so we would not lose the passing peer reviews that are expected by the public and the scientific community,” wrote Ketchum on the project’s website. The DeNovo Scientific Journal has no other studies, articles, papers or reviews, and only Ketchum’s paper has been “published” by the journal, NBC News pointed out. It also is not subscribed to by any major library or university, and its website apparently didn&#8217;t exist until three weeks ago. In the words of LiveScience&#8217;s Benjamin Radford, &#8220;It is not an existing, known or respected journal in any sense of the word.&#8221; (MORE: Scientist Sets Out to Prove Sasquatch’s Existence via Blimp) This isn’t the first time Ketchum’s Bigfoot DNA evidence has been met with criticism.  In November she released a statement about her Bigfoot findings, calling Bigfoot “a human hybrid&#8221; that had emerged 15,000 years ago through the mating of a human female and some other speciesunknown to science.  She has called on governments to recognize the Sasquatch as “an indigenous people and immediately protect their human and Constitutional rights.” At that time, the Bigfoot study had not been peer-reviewed — and according to NBC News, while the study has now been published, it still hasn&#8217;t been assessed by reputable scientists.<img alt="" border="0" src="http://stats.wordpress.com/b.gif?host=newsfeed.time.com&#038;blog=12783068&#038;post=196067&#038;subd=timenewsfeed&#038;ref=&#038;feed=1" width="1" height="1" />]]></description>

		<description><![CDATA[Under California law, a paleontologist and an archaeologist must be on-site to supervise during any new road construction — and in at least one case, this law has turned out to be quite useful. On Monday, two scientists who had been supervising a highway-widening project in Laguna Canyon announced they had identified four new whale species from a rock workers dug up sometime between 2000 and 2005, reported the journal Science. (More: The Realm of the Red Penguin: Peru&#8217;s Dead Sea of Fossils) Paleontologist Meredith Rivin of the John D. Cooper Archaeological and Paleontological Center in Fullerton, California told Science that the four new species were early toothed baleen whales that roamed the oceans some 17 to 19 million years ago — making them the youngest known toothed whale species. Rivin, who presented her study at AAAS on Monday, said the fourth new species, dubbed “Willy”, was a huge surprise itself. It was considerably larger than the other three and its teeth were badly worn, a sign suggesting that Willy’s diet consisted mostly of sharks, whose rough skin has resulted in similar patterns of wear in modern killer whales. Scientists are not strangers to roadcut science. In 2011, a team of researchers led by paleobiologist Nick Pyenson of the Smithsonian&#8217;s National Museum of Natural History identified a staggering 75 prehistoric whale skeletons at the site of a Chilean highway-widening project, according to the Daily Mail. Pyenson told Science that he was “excited” to see further analysis of the California fossils although he wasn’t sure what they would reveal about the early history of whale revolution.

		<description><![CDATA[It turns out Democrats and Republicans really do think differently. In a new study published in the journal PLOS ONE, a group of political scientists and neuroscientists have found that conservatives and liberals use different parts of their mind when making risky decisions, and that these differences in brain function can be used to predict party affiliation. (MORE: Getting Inside Your Head) Dr. Darren Schreiber, a researcher in neuropolitics at the University of Exeter, authored the study in collaboration with colleagues at the University of California. Speaking with TIME, Schreiber explains that the study used data from a previous experiment in which a group of people were asked to play a simple gambling task. The team took the brain activity measurements of this sample of 82 people and cross-referenced it with the participants’ publicly available political party registration data. “We found that you wouldn’t be able to see how Democrats and Republicans behaved differently in how they gambled, but if you looked into their brain, the differences in the levels of activity in different regions were substantial,” says Schreiber. (MORE: Why Women Are Better at Everything) They found that Republicans used their right amygdala, the part of the brain associated with the body’s fight-or-flight system, when making risk-taking decisions; Democrats tended to show greater activity in their left insula, an area associated with self and social awareness. Schreiber says that the study’s findings are consistent with similar studies that have been done around the world. “We are not overlapping in our results, but we are definitely looking at different parts of the same elephant,” he says. In a study published this month in the American Journal of Political Science, researchers at Brown University found that people who have more fearful dispositions were more inclined to be politically conservative. (MORE: The More Things Change: Looking Back On Presidential Calls For Bipartisanship) Schreiber is keen to stress that the ‘Red Brain, Blue Brain’ study does not show that humans are genetically hardwired to be a Democrat or a Republican, insisting that we are<img alt="" border="0" src="http://stats.wordpress.com/b.gif?host=newsfeed.time.com&#038;blog=12783068&#038;post=195522&#038;subd=timenewsfeed&#038;ref=&#038;feed=1" width="1" height="1" />]]></description>

		<description><![CDATA[The Food and Drug Administration has approved a “bionic eye” that allows blind people to see again – at least to an extent. The Argus II system, which is already in use in Europe, is designed to help patients with retinitis pigmentosa – a rare genetic disorder that damages and kills light-processing cells in the retina, and affects around 100,000 Americans, writes the WSJ. A miniature camera mounted on a pair of glasses transmits images to a belt-worn video processor. There, the images are converted into patterns of light and dark. This data is then sent wirelessly to a sheet of electrodes implanted in the retina, simulating pixels of light that the eye &#8216;sees&#8217;. This information is then sent to the brain and processed normally as an image, as this video from the Argus II&#8217;s manufacturer, Second Sight Medical Products of California, explains: MORE: First European Embryonic Stem Cell Trial Gets Green Light The device, which costs about $150,000 not including implant surgery or training,  can’t make a blind person see — at least not in the normal sense. But it can allow them to identify contours and boundaries of objects, particularly when there is contrast between light and dark – allowing them to distinguish, for example, curbs from asphalt roads whilst walking along. &#8220;Without the system, I wouldn’t be able to see anything at all, and if you were in front of me and you moved left and right, I’m not going to realize any of this,&#8221; 74-year-old Elias Konstantopolous, who is one of about 50 people who have been using the Argus II in trials for several years, told the New York Times. &#8220;When you have nothing, this is something. It’s a lot.” Dr. Mark S. Humayun, an ophthalmologist and biomedical engineer at the University of Southern California, spent 20 years developing the device. He told the New York Times that he envisions using the technology to treat other conditions such as  bladder control problems or spinal paralysis by implanting electrodes in those parts of the body.

		<description><![CDATA[For all our obsession with the possibility of intelligent alien life, the search for E.T. has so far been a letdown. SETI, the organization famously scouring the heavens for alien life by scrutinizing radio signals for decades, has turned up nothing to speak of. What&#8217;s a self-respecting alien-hunter to do? Start scrutinizing exoplanets more closely, for starters &#8212; specifically their colors, say scientists in a new paper titled &#8220;Colors of Extreme Exo-Earth Environments.&#8221; (MORE: World’s Oldest Wild Bird Stumps Scientists By Giving Birth at Age 62) Let&#8217;s talk lingo: An &#8220;exoplanet&#8221; is just the fancy scientist way of referring to planets found orbiting stars outside our solar system. We&#8217;ve identified slightly more than 850 so far, with upwards of 18,000 additional candidates awaiting verification. And that&#8217;s just the start: NASA reports there may be hundreds of billions of exoplanets winging around our Milky Way galaxy alone. Here&#8217;s another funny-sounding term: extremophiles, the word we use for microorganisms that can exist in humans might consider extreme environmental conditions — say in hydrothermal vents at the bottom of Earth&#8217;s oceans, or on the surface an exoplanet. Scientists at the Max Planck Institute for Astronomy in Heidelberg, Germany and the Harvard-Smithsonian Center for Astrophysics in Cambridge, Mass. are suggesting we start paying attention to these planets&#8217; spectrographic fingerprints, using that as a way to narrow our search for alien life. The Earth, for instance, generates light at the near-infrared end of the electromagnetic spectrum because of the chlorophyll in plants. Looking for planets that exhibit a comparable &#8220;red edge&#8221; could indicate the presence of alien plant life. (VIDEO: Life in the Universe: Easy or Hard?) And since we&#8217;ve already detected rocky planets orbiting in the habitable zones of their stars, the scientists studied extreme Earth-based environments that harbor extremophiles to identify the &#8220;characteristic albedos&#8221; we might use to find comparably durable exoplanet-based alien microorganisms. Little gray aliens with almond eyes or long-necked ones with glowing fingers it&#8217;s not, but at this point, just finding a bunch of alien microorganisms &#8212; to say nothing of something like an alien<img alt="" border="0" src="http://stats.wordpress.com/b.gif?host=newsfeed.time.com&#038;blog=12783068&#038;post=194893&#038;subd=timenewsfeed&#038;ref=&#038;feed=1" width="1" height="1" />]]></description>

		<description><![CDATA[How do you turn a tiny science-city at the far end of the earth into a flexible biosphere capable of skating around vast fields of ice with up to 90 m.p.h. winds and temperatures that can drop below 100 degrees F? Like this: Imagine something that&#8217;s a squatter, bluer version of the sandcrawler in Star Wars, multiplied sevenfold, with each structure linked like train cars. Now perch it high above the ground on hydraulically elevated legs that are capped off with ski-like &#8220;feet.&#8221; Finally, place this bizarre-sounding &#8220;centipede city&#8221; somewhere in a beautifully austere, wind-scoured snowscape &#8212; say, Antarctica &#8212; and you get Halley VI, the world&#8217;s first perambulatory municipality. A moveable city. (MORE: Tonik, the Dog with the Human Face, Is Up for Adoption) Well, maybe calling it a &#8220;research center&#8221; would be more accurate, because that&#8217;s it&#8217;s main purpose on the floating ice shelf just 900 miles or so from the South Pole itself. Credit goes to British design outfit Hugh Broughton Architects, who pulled the $41 million project together after winning an international competition for a &#8220;self-sufficient scientific research base.&#8221; And yes, it can actually move, though not under its own power: It has to be towed by bulldozers. According to the designers, the hydraulic legs allow each module to climb up out of the annually occurring snow, which would otherwise leave the research structures buried. Modularity and mobility were essential toward winning the contract: The ice shelf Halley VI rests on moves 1300 feet each year into the sea, thus the need to periodically haul it back inland. And breaking the station into component sections &#8212; labs, sleeping quarters, energy centers and recreation areas &#8212; allows it to be rearranged at will. All practicality aside, if you just squint a little, you can almost see this thing popping up, George Lucas-CGI-rethink-style, in one of the The Empire Strikes Back&#8216;s opening scenes.

		<description><![CDATA[It&#8217;s mathematicians&#8217; idea of an arms race: the unending quest to find the largest prime number. Like an archaeological expedition, a new number has taken top honors as the longest &#8212; and it&#8217;s over 17 million digits long. Curtis Cooper, a researcher at the University of Central Missouri, reportedly spent four years searching for the new prime number. And in late January, his quest was confirmed. Behold the new longest prime number in the world: 257,885,161 &#8211; 1. The new discovery, at 17,425,170 digits, crushes the 2008 record number of 12,978,189 digits. Cooper is something of a legend when it comes to prime-number discovery: this is the third one found by him and his team. Prime numbers are numbers that can only be divided by themselves and 1, with the first-appearing ones being 2,3,5,7 and 11. This new king of primes is also a member of a rare collection known as the Mersenne primes. Named after their discoverer Marin Mersenne, a 17th century French monk, the numbers are all expressed as 2 raised to the power of &#8220;P&#8221; minus 1, of which P is also a prime. The newly identified number is the 48th known Mersenne prime. (MORE: Best Inventions of 2008: The 46th Mersenne Prime) While searching for prime numbers could be a laborious task, as every number has to be thoroughly tested for divisors, this and all other largest prime numbers are now found via an Internet searching system called the Great Internet Mersenne Prime Search. The system, abbreviated to GIMPS, harnesses the computing power of 360,000 volunteer processors to find new, ever-larger primes, according to the Huffington Post. After Cooper made his discovery, one computer among his prime-searching network spent 39 days to prove that the number was truly prime. Other independent researchers, according to the New Scientist, then verified the discovery. There is little known mathematical value to finding new primes, but these rare numbers are prized as badges of honors because of their sheer rarity. &#8220;Every time I find one it is incredible,&#8221; Cooper told the<img alt="" border="0" src="http://stats.wordpress.com/b.gif?host=newsfeed.time.com&#038;blog=12783068&#038;post=194224&#038;subd=timenewsfeed&#038;ref=&#038;feed=1" width="1" height="1" />]]></description>

		<description><![CDATA[You&#8217;d think the records would have to do with a figure like &#8220;50 million&#8221; &#8212; the number of cosmic rays an NASA science ballon drifting over Antarctica recently intercepted &#8212; but it actually involves a pair of flight duration records. The large, unmanned helium balloon, impressively dubbed the Super Trans-Iron Galactic Element Recorder (or Super-Tiger for short), took off on Dec. 8, 2012 from a launch site near McMurdo Station, a U.S. research center located on the southern tip of Antarctica&#8217;s Ross Island. Thereafter, it hovered for more than 55 days at 127,000 feet &#8212; about as high as Austrian daredevil Felix Baumgartner&#8217;s epic jump last October &#8212; before NASA brought it down to complete the mission last Friday. (MORE: Arkansas Couple Wins Lottery Twice in One Day) Super-Tiger clinched its first record, &#8220;longest flight by a balloon of its size,&#8221; on Jan. 24 after flying for 46 days. It grabbed its second, &#8220;longest flight of any heavy-lift scientific balloon,&#8221; on Friday upon landing, clocking in at 55 days, one hour and 34 minutes aloft, edging past NASA&#8217;s Super Pressure Balloon, the previous record-holder, which flew for 54 days, one hour and 29 minutes in 2009. These &#8220;long duration&#8221; science balloon are able to fly as long as they do because of unique conditions at the South Pole involving steady temperatures and a persistent low-pressure system called the &#8220;polar vortex.&#8221; Because of the constant daylight during Antarctic summers, day/night temperature fluctuations don&#8217;t occur, and the lack of heat-producing population centers also helps. Xtreme Sports Science records aside, the Super-Tiger&#8217;s raison d&#8217;être involved deploying a new instrument designed to sort heavier-than-iron elements from other high-energy cosmic rays. The balloon apparently gathered so much data that NASA&#8217;s saying it could take two years to pore over. It&#8217;s purpose: to help scientists better understand where these elements come from, and how they achieve such high energies.

		<description><![CDATA[The heat produced by in cities like New York and San Francisco may be contributing to warming in areas up to 1,000 miles away, according to National Geographic News. Scientists have long been familiar with the “urban island heat effect,&#8221; which generally leads to higher temperatures in cities than in suburban and rural areas. (MORE: The Scariest Environmental Fact in the World) However, according to a new study from the Scripps Institution of Oceanography at the University of California, San Diego, the heat generated by cities in the Northern Hemisphere is altering the jet stream – a current of air high above the surface of the Earth – and other major atmospheric systems, resulting in an increase in winter temperatures of up to 1.8°F (1°C) in faraway rural areas. According to the new models, air rising off of urban areas can interfere with the jet stream, allowing warmer air from the Equator to flow farther north, according to National Geographic News. (MORE: Federal Forecast for Climate Change: It’s Getting Hot in Here “The changed circulation is thought to have an opposite effect in Europe, causing a cooling effect that amounts to 1.8°F (1°C), experienced mostly in the fall,” NBC News reported. The authors of the study, published in the journal Nature Climate Change, said that urban heat might be behind some parts of the planet warming faster than models have predicted, NBC News reported. The researchers found that areas most significantly impacted by this urban heat effect were Siberia and northern Canada, which can see temperatures rise 1.4°F to 1.8°F (0.8°C to 1°C) due to urban heat from cities thousands of miles away affecting the jet stream. The 86 major metropolitan areas of the Northern Hemisphere cover only 1.27 percent of the Earth’s surface.  But those areas consume 6.7 terawatts (one terawatt equals 1 trillion watts) of energy annually – representing 41.8 percent of annual global energy consumption, National Geographic News reported.
