Launch Your Own Nanosatellite Into Space 119

Posted by samzenpus from the my-first-satellite dept.
First time accepted submitter Rozine writes "Ever wanted to launch your own satellite into space? Thanks to a project at the Cornell Space Science Lab, now you can. In the words of the grad student leading the project, Zac Manchester, 'What better way of showing off your uber-geek credentials than having your own spacecraft?' Zac hopes that by shrinking the size of each spacecraft and using advancements in computer and solar cell technology, satellites can follow the path of the personal computer revolution, opening up space for the masses. For small donations you will receive mementos, but for $300 and up you will get your very own satellite to be launched into space. Perfect for slashdotters and school projects everywhere!" We covered this project in its infancy back in July. I'm glad to see it gained traction.

Genes About a Quarter of the Secret To Staying Smart 77

Posted by samzenpus from the luck-of-the-draw dept.
ananyo writes "A Scottish intelligence study that began 80 years ago has borne new fruit. Researchers have tracked down the study's surviving participants — who joined the study when they were 11 years old — to estimate the role that our genes have in maintaining intelligence through to old age. After conducting fresh intelligence tests on the surviving participants, the researchers tested the DNA samples they had collected for the presence of more than half a million common genetic variants, each affecting only a single letter in the DNA sequence of the genome. The team then calculated whether these variants were associated with cognitive stability — how well intelligence had been maintained over time. The sample size of 2,000 people was too small to grant the statistical power needed to track down individual genetic signatures associated with cognitive stability. But it was enough to estimate how much genetics contributes to cognitive aging. The team found that these variants accounted for nearly one-quarter of the differences in cognitive stability."

A Planet Literally Boils Under the Heat of Its Star 163

Posted by Soulskill from the cosmic-recycling-project dept.
The Bad Astronomer writes "Astronomers have found what appears to be a planet so hot it's literally vaporizing, boiling away from the heat of its star. KIC 12557548b was found using the transit method, periodically blocking some light from its star as it orbits around. But the amount of light blocked changes every transit. Given it's less than a million miles from the surface of the star, astronomers interpret this (PDF) as the planet itself turning to vapor, and the expanding cloud of rock-laden gas is what's blocking the starlight. The planet is most likely somewhat bigger than Mercury, but losing 100,000 tons of matter every second it'll only be around another few hundred million years."

Town Turns Off the Lights To See the Stars 222

Posted by samzenpus from the we're-going-dark dept.
Hugh Pickens writes "Stargazing skies all over the world are disappearing, as the sky above New York City is Class 9 on the Bortle ranking and American suburban skies are typically Class 5, 6, or 7. But some places are making an effort to preserve their skywatching heritage as Exmoor National Park was granted International Dark-Sky Reserve status in November and people in the Exmoor town of Dulverton were challenged to switch off their lights as part of the BBC's Stargazing Live, demonstrating that you don't need special equipment to see the stars more clearly, if you have a decent pair of binoculars. 'The whole idea is to show that even a small town, which is still quite dark, can give off quite a lot of light,' says astronomer Mark Thompson. The event in Dulverton gained a lot of support from local residents and businesses. 'It needed a bit of organization to get everyone to say yes,' says town mayor Chris Nelder. 'We want people to just enjoy the night sky, to treasure the fact we have them and to look after them,' adds Claire O'Connor from Exmoor National Park Authority."

US Finally Backs International Space "Code of Conduct" 116

Posted by samzenpus from the space-rules dept.
coondoggie writes "Perhaps it was the concern that the nearly 14 ton Russian Mars probe would land smack-dab on the White House or maybe they just came to their senses, but the U.S. State Department today said it would indeed work with the European Union and other countries to develop a formal space code of conduct. Of particular concern is the growing amount of space trash and how the world can go about eliminating or controlling the problem. There is also the desire to keep space free of military weaponry."

But that doesn't mean that the glistening yellow cape—the world's largest garment made entirely from spider silk—isn't a massive feat of engineering to be marveled. Now on public display for the first time at the Victoria & Albert Museum in London, the textile gets its unearthly gleam from the undyed filaments of the golden orb spider, a species of arachnid commonly found in Madagascar."

Silver Solution Ink Makes Faster Flexible Circuits 36

Posted by samzenpus from the quick-silver dept.
judgecorp writes "Silver-based compounds dissolved in ammonia could make finer and more flexible circuits, according to researchers at the University of Illinois. Existing inkjet based circuit printing systems use particles which are less predictable. The silver-based ink remains dissolved until the ammonia evaporates, and can be delivered through 100nm nozzles. In all senses, it's a better solution."

Multicellular Life Evolves In Months, In a Lab 285

Posted by Soulskill from the selecting-for-extroverted-cells dept.
ananyo writes "The origin of multicellular life, one of the most important developments in Earth's history, could have occurred with surprising speed, U.S. researchers have shown. In the lab, a single-celled yeast (Saccharomyces cerevisiae) took less than 60 days to evolve into many-celled clusters that behaved as individuals. The clusters even developed a primitive division of labor, with some cells dying so that others could grow and reproduce. Multicellular life has evolved independently at least 25 times, but these transitions are so ancient that they have been hard to study. The researchers wanted to see if they could evolve multicellularity in a single-celled organism, using gravity as the selective pressure. In a tube of liquid, clusters of yeast cells settle at the bottom more quickly than single cells. By culturing only the cells that sank, they selected for those that stick together. After many rounds of selection over 60 days, the yeast had evolved into 'snowflakes' comprising dozens of cells."

New Mexico Is Stretching, GPS Reveals 117

Posted by Soulskill from the too-many-tacos dept.
Velcroman1 writes "New Mexico's borders are gradually gaining girth, according to the Albuquerque Journal. It's not much, and it's not happening very fast — the state is getting about an inch wider every 40 years — but the state is unquestionably expanding, according to University of Colorado geophysicist Henry Berglund and his colleagues. Using a collection of 25 extra-precise GPS receivers planted across New Mexico and Colorado, Berglund determined that the cities of Albuquerque and Santa Fe are creeping away from each other. The rate of change seems ever so slow to the untrained ear, described as approximately 1.2 'nanostrains' per year."

Martian Rocks Land In Morocco 95

Posted by Soulskill from the never-been-jealous-of-morocco-before dept.
Hugh Pickens writes "Scientists have confirmed chemically a recent and rare invasion from Mars with 15 pounds of fresh Martian rocks falling in Morocco last July. A special committee of meteorite experts, which includes some NASA scientists, confirmed the test results Tuesday certifying that the meteorites recently collected came from Mars. The biggest rock weighs more than 2 pounds. Astronomers think that millions of years ago something big smashed into Mars that sent fragments hurtling through the solar system. Occasionally, some fall on Earth."

Forget Space Beer, Order Meteorite Wine Instead 77

Posted by Soulskill from the it-has-a-subtle,-cloying-grit-to-it dept.
astroengine writes "Chances are, when you pop open a bottle of Cabernet Sauvignon, you expect to savor certain aromatic flavors, or 'notes,' depending on the wine: fruit forward, perhaps, with hints of pepper and leathery tannins, and just the faintest whiff of... meteorite??? At least that's what you'd savor if you were drinking a bottle of Meteorite, possibly the very first wine on the market aged with a meteorite that fell to Earth from space. It's the brainchild of Ian Hutcheon, an Englishman now working in Chile, who thinks the infusion of a bit of meteorite gives his wine a 'livelier taste.'"

Statisticians Uncover the Mathematics of a Serial Killer 164

Posted by Unknown Lamer from the something-about-murders-and-statistics dept.
Hugh Pickens writes writes "Andrei Chikatilo, 'The Butcher of Rostov,' was one of the most prolific serial killers in modern history committing at least 52 murders between 1978 and 1990 before he was caught, tried, and executed. The pattern of his murders, though, was irregular with long periods of no activity, interrupted by several murders within a short period of time. Hoping to gain insight into serial killings to prevent similar murders, Mikhail Simkin and Vwani Roychowdhury at UCLA built a mathematical model of the time pattern of the activity of Chikatilo and found the distribution of the intervals between murders follows a power law with the exponent of 1.4. The basis of their analysis is the hypothesis that 'similar to epileptic seizures, the psychotic affects, causing a serial killer to commit murder, arise from simultaneous firing of large number of neurons in the brain.' In modeling the behavior the authors didn't find that 'the killer commits murder right at the moment when neural excitation reaches a certain threshold. He needs time to plan and prepare his crime' so they built delay into their model. The killings eventually have a sedative effect, pushing the neuronal activity below the 'killing threshold' – which is why there are large intervals of time between groups of murders. 'There is at least qualitative agreement between theory and observation [PDF],' conclude the authors. 'Stats can't tell you who the perp is, but they're getting better and better at figuring out where and when the next crime might happen,' writes criminal lawyer Nathaniel Burney adding that 'catching a serial killer by focusing resources based on when and where he's likely to strike next is a hell of a lot better than relying on the junk science of behavioral profiling.'"

Putting Medical Records Into Patients' Hands 211

Posted by samzenpus from the taking-your-life-in-your-hands dept.
Hugh Pickens writes "Roni Caryn Rabin says patients have a legal right to their medical records, though access can prove difficult. But what would happen if patients were encouraged not just to see their medical records but to take them home, study them and really own them? A research collaboration called OpenNotes set out to answer this question, publishing the first results of a study on physician and patient attitudes toward shared medical records and demonstrating that for patients, at least, shared medical records seems to be an idea whose time has come. 'That's the great challenge in medicine: getting patients to be more active in their own care,' says Dr. Tom Delbanco, a principal investigator of the study. 'What we're doing is opening the black box and letting you look inside.' Dr. Delbanco and his colleagues recruited more than 100 primary care doctors who were already using electronic health records to volunteer to share their medical notes with patients. Patients were enthusiastic: 90 percent thought they would be more in control of their care if they saw the notes. They weren't worried about being confused and most said seeing the record would help them take better care of themselves helping them better remember their treatment plan, understand it and take their medication. The goal is to engage patients more fully in their own health. 'Knowledge is power,' says Jan Walker, the study's senior author. 'A patient goes to the doctor only once in a while, but in between visits, you're making all kinds of decisions that affect your health every single day.'"

sciencehabit writes "If you've ever wondered what a virus sounds like, or what noise a bacterium makes when it moves between hosts, you may soon get your chance to find out. Scientists have created the world's tiniest ear. The 'nano-ear,' a microscopic particle of gold trapped by a laser beam, can detect sound a million times fainter than the threshold for human hearing. Researchers suggest the work could open up a whole new field of 'acoustic microscopy,' in which organisms are studied using the sound they emit."
