North Star May Be Wasting Away 129

Posted by Soulskill from the julius-caesar-wanted-to-go-on-a-diet dept.
sciencehabit writes "The North Star, a celestial beacon to navigators for centuries, may be slowly shrinking, according to a new analysis of more than 160 years of observations. The data suggest that the familiar fixture in the northern sky is shedding an Earth's mass worth of gas each year."

Bill Gates Gives $750M To AIDS Fund 214

Posted by Soulskill from the chunk-of-change dept.
redletterdave writes "Microsoft chairman and philanthropist Bill Gates pledged $750 million to the troubled global AIDS fund on Thursday and urged governments to continue their support to save lives. Since the fund was launched 10 years ago, the Bill & Melinda Gates Foundation has given $1.4 billion to the charity, having already contributed $650 million prior to the latest donation. The Global Fund to Fight AIDS, Tuberculosis and Malaria accounts for around a quarter of international financing to fight HIV and AIDS, as well as the majority of funds to fight TB and malaria."

Russian Rocket Fleet Grounded Again 66

Posted by Soulskill from the orbital-decay dept.
Velcroman1 writes "Failed pressure chamber tests have forced Russia to postpone two manned launches to the International Space Station — echoing a 2011 situation that left the country's space transport vehicles grounded and led to speculation that scientists may be forced to abandon the orbiting space base. Six astronauts are currently aboard the ISS including two Americans: Commander Dan Burbank and Flight Engineer Don Pettit. 'There is plenty of margin for the current space station crew to stay onboard longer, if necessary, and plenty of margin in our manifest for upcoming launches,' a NASA spokeswoman said. But Soyuz issues are scary nonetheless. 'This re-entry capsule now cannot be used for manned spaceflight,' an unnamed source told Interfax."

Mars Rover Opportunity Turns 8 151

Posted by Soulskill from the its-doing-science-and-its-still-alive dept.
New submitter el borak writes "Never mind all the talk about the revival of the American auto industry. What may be the greatest car the U.S. has ever built is currently a tidy 78 million miles (125m km) away from this world — resting on the edge of Endeavour crater in the southern hemisphere of Mars. It was on January 25, 2004 that the rover Opportunity bounced down on Mars for a mission designed to last a minimum of three months and a maximum of just a year or two."

Graphene Membranes Superpermeable to Water 292

Posted by Soulskill from the it-slices-it-dices dept.
Dr Max writes "Not only is graphene the strongest, thinnest and best conducting material known to man, it is now shown to have superpermeability with respect to water as well. This allows a membrane made with graphene to pass water right through it (PDF), while another atom or molecule (even helium) gets blocked. 'The properties are so unusual that it is hard to imagine that they cannot find some use in the design of filtration, separation or barrier membranes and for selective removal of water,' said one of the researchers."

Scientists Organize Elsevier Boycott 206

Posted by Soulskill from the information-wants-to-be-free dept.
An anonymous reader writes "The academic publisher Elsevier has attracted controversy for its high prices, the practice of bundling journals for sale to libraries and its support for legislation such as SOPA and the Research Works Act. Fields medal-winning mathematician Tim Gowers decided to go public with a blog post describing how he'll no longer have anything to do with Elsevier journals, and suggesting that a public website where mathematicians and scientists could register their support for an Elsevier boycott would further the cause. Such a website now exists, with hundreds of academics signing-up so far. John Baez has a nice write-up of the problem and possible solutions."

Scientists Create World's First Atomic X-Ray Laser 145

Posted by samzenpus from the what-could-go-wrong? dept.
New submitter newmission33 writes "Government researchers have created the fastest, purest X-ray laser pulses ever achieved, and have fulfilled a 1967 prediction that an atomic scale X-ray laser could be made in the same manner as visible-light lasers, according to a statement released Wednesday. Researchers at the SLAC National Accelerator Laboratory used the Linac Coherent Light Source to aim a powerful X-ray source beam, a billion times brighter than any previous source, at a capsule of neon gas and triggered an 'avalanche' of X-ray emissions to become the world's first 'atomic X-ray laser.'"

Pac-Man Is NP-Hard 195

Posted by samzenpus from the not-all-fun-and-games dept.
MrSeb writes "An Italian researcher with a penchant for retro games — or perhaps just looking for an excuse to play games in the name of science! — has used computational complexity theory to decide, once and for all, just how hard video games are. In a truly epic undertaking, Giovanni Viglietta of the University of Pisa has worked out the theoretical difficulty of 13 old games, including Pac-Man, Doom, Lemmings, Prince of Persia, and Boulder Dash. Pac-Man, with its traversal of space, is NP-hard. Doom, on the other hand, is PSPACE-hard."

11 New Multi-Planet Star Systems Discovered 109

Posted by timothy from the ok-now-sort-on-forest-moon dept.
astroengine writes "The number of known multi-planetary star systems has just tripled. What's more, the Kepler space telescope science team has just announced that they have doubled the number of confirmed exoplanetary sightings made by the observatory. Some of the newly discovered worlds are only 1.5 times the size of Earth, while others are bigger than Jupiter. Fifteen exoplanets are between Earth and Neptune in size, but further observations will be needed to determine if any have a rocky surface like Earth, or a gaseous consistency like Neptune."

Object Lesson in Non-Transparency At Energy.gov 111

Posted by timothy from the but-it's-a-dry-heat-death dept.
Harperdog writes "Dawn Stover recounts her attempts to access information at energy.gov, the U.S. Energy Department's 'cutting-edge, interactive information platform,' which apparently isn't any of those things. Especially frustrating were her attempts to locate important documents related to the Yucca Mountain nuclear waste repository. An interesting read for anyone interested in true government transparency."

Top Google Executives Approved Illegal Drug Ads 287

Posted by timothy from the regulations-trump-free-choice dept.
Hugh Pickens writes "PC Magazine reports that the U.S. government used convicted con artist David Whitaker, owner of an online business selling steroids and human growth hormone to U.S. consumers, to help federal agents in a sting operation against Google when he began advertising with Google with advertisements that included the statement 'no prescription needed,' clearly violating U.S. laws. Google's settlement with the U.S. government for $500 million blamed AdWords sales by Canadian pharmacies, who allegedly were selling drugs to U.S. consumers. 'We banned the advertising of prescription drugs in the U.S. by Canadian pharmacies some time ago,' Google said then. 'However, it's obvious with hindsight that we shouldn't have allowed these ads on Google in the first place.' Peter Neronha, the U.S. attorney for Rhode Island who led the multiagency federal task force that conducted the sting, claims that chief executive Larry Page had personal knowledge of the operation, as did Sheryl Sandberg, a Google executive who now is the chief operating officer for Facebook. In 2009 Google started requiring online pharmacy advertisers to be certified by the National Association of Boards of Pharmacy's Verified Internet Pharmacy Practices Sites program and hired an outside company to detect pharmacy advertisers exploiting flaws in the Google's screening systems."

NASA Releases New High-Definition Image of Earth 106

Posted by timothy from the texas-centric-view dept.
New submitter klchoward writes "Working for NOAA, I have been really pleased to see the weather data from the new Suomi NPP satellite coming into our computer models already but have been blown away by its capability to take stunning high-definition images of our planet. See the article at Huffington Post or go straight to the image at NASA's website." Reader derekmead has some images from further afield, too: these beautiful images of Mars come from NASA's High Resolution Imaging Science Experiment camera, mounted on the Mars Reconnaissance Orbiter.

Candidate Gingrich Pushes a Moon Base, Other Space Initiatives 602

Posted by timothy from the in-space-no-one-can-hear-your-loss-for-words dept.
New submitter thomas.kane writes "Newt Gingrich announced yesterday, while visiting Florida's Space Coast, a visionary plan for the future of space travel. He suggested a combination of the current private incentives and a government funded section, developing a moon base, commercial near earth orbit, and continuous propulsion systems to better reach Mars." "Visionary" seems an awfully positive spin on it; Gingrich is not the first President or presidential candidate to propose revisiting the moon — and the moon seems like small potatoes, by some measures.

That same planetarium, now under Tyson's direction, is currently undergoing a transformation the likes of which Neil's young self couldn't have possibly imagined: It's becoming a giant videogame."

2012 Japan Prize Honors Magnet Creator and Cancer Researchers 28

Posted by Unknown Lamer from the turns-out-magnets-work-using-science dept.
alphadogg writes with an excerpt from a Network World article: "The 2012 Japan Prize, one of the world's most prestigious science and technology honors, has been awarded to three American medical experts who are fighting cancer as well as to a Japanese inventor whose magnet technology has implications for energy conservation. In years past, the prize (which comes with a $650K purse) has honored computing accomplishments, including last year, when Unix inventors Dennis Ritchie and Ken Thompson were honored."

The High-Radiation Lives and Risks of Nuclear-Nomad Subcontractors 96

Posted by timothy from the stop-that-incessant-ticking dept.
Harperdog writes "Gabrielle Hecht has an interesting piece on the subcontracted workers of the nuclear energy industry, in Japan and elsewhere. These workers face far more exposure to radiation than salaried workers; in Japan, 90% of the nuclear workforce is contracted. This is an eye-opening look at a practice that 'carries exceptional risks and implications. And until these are recognized and documented, complex social and physiological realities will continue to be hidden.' A good read, but I would like to know how the Fukushima 50 are doing."
It's funny. Laugh.

Psychics Say Apollo 16 Astronauts Found Alien Ship 285

Posted by Unknown Lamer from the scully-says-yeah-right dept.
astroengine writes "A group called Transception Incorporated, self-described as an Austin, Texas-based psychic R&D operation, sent a letter (PDF) to NASA Administrator Charles Bolden that nominates the Apollo 16 crew for the Congressional Space Medal of Honor. Why? Well, a variety of 'shipwreck elements' on the Moon — described as 'structures, people/aliens, biological technology, and their plight' — were reportedly 'seen' through remote viewing (PDF) by six experts at Transception. These 'elements' can be seen, along with Apollo 16 moonwalkers John Young and Charles Duke, in photographs during that famous mission, obviously making this the first ever alien encounter."

Embryonic Stem Cell Retinal Implants Seem Safe, So Far 91

Posted by timothy from the it's-that-or-the-lasik dept.
An anonymous reader writes "A biotechnology company said Monday that results from the world's first human trial using embryonic stem cells to treat eye diseases suggested that the new procedure appears to be safe four months after the cells were injected into the eyes of two blind patients. The study also describes visual improvements in patients, and experts said the findings hold promise for treating blindness in patients with currently incurable conditions like age-related macular degeneration in older patients and Stargardt's Disease, a main cause of blindness in young people."
