Biologist Colleen Handel saw her first black-capped chickadee with the heartrending disorder in 1998. The tiny birds showed up at birdfeeders in Alaska's largest city with freakishly long beaks. Some beaks looked like sprung scissors, unable to come together at the tips. Others curved up or down like crossed sickles. Handel, a U.S. Geological Survey bird specialist, was sure the cause of avian keratin disorder would be found quickly: contaminated birdseed, a poison targeting spruce bark beetles, maybe some sort of bacterium or fungus. Years went by. She found herself losing sleep over a mysterious ailment afflicting 6.5 percent of south-central Alaska's black-capped chickadees and 17 percent
Think autism and an image of an awkward boy typically emerges. The developmental disorder is at least four times more common in boys, but scientists taking a closer look are finding some gender-based surprises: Many girls with autism have social skills that can mask the condition. The gender effect is a hot topic in autism research and one that could lead to new ways of diagnosing and treating a condition that affects at least 1 in 68 U.S. children.
In the Sonoran Desert, a body laid gently on its side, its arms crossed, its knees bent toward its chest, tells the story of someone who was loved and respected, whose community mourned her once she was gone. The University of Arizona bioarchaeologist studies “atypical” burials — bodies tossed haphazardly into graves headfirst, their bones broken, their limbs splayed. In a new study in the journal Current Anthropology, Watson and doctoral student Danielle Phelps argue that these burials are a sign of the violent circumstances surrounding deaths that happened thousands of years ago. “These people were buried very differently than the rest of the community, and we're trying to understand why that is,” Watson said in a news release.
The national group last week unveiled a new set of guidelines that allow for certain types of media use by younger children and set broader parameters for older kids to keep them well-rested, physically active and socially engaged. "Parents can set expectations and boundaries to make sure their children's media experience is a positive one," she said. The AAP's recommendations were published online Friday in the journal Pediatrics.
The National Assessment of Educational Progress, or NAEP, is called The Nation's Report Card for good reason; the tests are administered the same way year after year, using the same kind of test booklets, to students across the country. That allows researchers and educators to compare student progress over time. NAEP tests serve as a big research project to benchmark academic achievement in subjects like science, math, reading, writing, civics, economics, geography and U.S. history. Science results were out Thursday for 4th, 8th, and 12th graders. Among seniors, achievement was flat, and performance gaps by race, ethnicity and gender persisted. But fourth- and eighth-graders showed modest progress:

Russia is claiming that the Afghanit active protection system (APS) mounted on Moscow’s powerful new T-14 Armata main battle tanks has been proven effective at intercepting depleted uranium-core armor-piercing fin-stabilized discarding sabot (APFSDS) cannon shells. If Moscow’s claims are accurate, the new Russian active protection system would be a game-changing development in the realm of mechanized warfare. While active protection systems were thought to be effective mostly against incoming anti-tank missiles and rocket propelled grenades, most industry and defense experts had believed that active protection systems were ineffective against kinetic energy (KE) round such as the U.S. Army’s M829A4 120mm APFSDS.
This event will feature more than 40 different speakers from the food and agriculture field. Researchers, farmers, chefs, policymakers, government officials, and students will come together for interactive panels, networking, and delicious food, followed by a day of hands-on activities and opportunities for attendees. Food Tank recently had the opportunity to speak with Fred Kirschenmann, Distinguished Fellow at the Leopold Center for Sustainable Agriculture and President of the Stone Barns Center for Food and Agriculture, who will be speaking at the summit.
On current trends, stocks of global wildlife could plunge two-thirds by 2020, an annual decline of two percent, conservation group WWF and the Zoological Society of London warned in their joint biennial Living Planet report. "This should be a wake-up call to marshal efforts to promote the recovery of these populations," said Ken Norris, director of science at the Zoological Society of London.
Across the world, women now consume nearly as much alcohol as men do, according to a new study. The findings show that the gap between men's and women's drinking habits is closing. This is particularly true for women born in the last 15 to 25 years
Tabby's Star, scientifically known as KIC 8462852, has become a point of great intrigue in the ongoing search for extraterrestrial life following wild-sounding ideas that an "alien megastructure" could be there. Now UC Berkeley's Breakthrough Listen program is doing to explore that mystery more deeply than ever, thanks to funding by Russian billionaire investor Yuri Milner. The flickering gave rise to theories of an "alien superstructure," possibly a Dyson sphere being used to capture the star's energy. While that's the most outlandish theory, there are also several more that attempt to explain what's happening at Tabby's Star, including the idea that it's brightness is being blocked by the debris of a destroyed planet.
Singapore's manufacturing output has seen an improvement in the month of September as it recorded a 6.7% increase. What gave the manufacturing sector a surprise increase was the surge in biomedical cluster, which upticked 22.2% in the said month. According to the figures released by the Economic Development Board, the pharmaceuticals segment expanded 26.9% due to higher production of active pharmaceutical ingredients and biological products, while the medical technology segment grew 9.6% with higher export demand for medical instruments.
A subversive influx of mild, dense salt water is undermining the vast ice shelves of the West Antarctic Ice Sheet, and threatening to destabilize the entire region, thereby raising sea levels worldwide by at least four, and possibly as much as 15 feet.
Post written byVincent Ialenti and Annie Tomlinson The authors are National Science Foundation Graduate Research fellows and PhD students at Cornell University. Nuclear technologies have long evoked grand images—from billowing mushroom clouds to massive concrete cooling towers looming above nuclear power plants. This bigness has been engrained in our very language. A person can, for example, take the “nuclear option” – the most extreme course of action – when making a difficult decision. In anger, a person might “go nuclear,” exploding into rage. In many ways, nuclear technologies earned their reputations for their huge scale. Since the 1950s, the size of nuclear power reactors has grown from
A mysterious structure orbits a star almost 1,500 light-years from Earth. Most astronomers remain skeptical about that but are nonetheless intrigued as Search for Extraterrestrial Intelligence (SETI) projects to observe Tabby’s star continue. Now, a team of University of California, Berkeley astronomers have turned their gaze toward Tabby’s Star as a part of its 10-year, $100 million initiative to find extraterrestrial intelligence.
Now that General Electric Co. CEO Jeff Immelt has moved to Boston, he doesn’t want anyone else to leave. Speaking Tuesday night at Dana-Farber Cancer Institute’s Joint Visiting Committee Symposium, which brings together and educates the hospital’s donors and community ambassadors, Immelt said he moved his company to Boston to be immersed in "a sea of ideas." Now he wants to make sure the people behind Boston’s health care ecosystem aren’t leaving. “One of our hypotheses in moving here was … this was kind of a wasted ecosystem — if you look at Silicon valley, Sand Hill Road, everything around Stanford. There’s no reason all of that couldn't be, in some shape or form, here,” Immelt said. “I think
There are more than 30 million research papers out there, and more than 3,000 papers are published every day. Put simply, you haven’t a chance in hell to read all of them. So what’s a poor researcher to do when set a challenge in a brand new field of research? Once the wave of blind panic and urge to drink copious amounts of gin has dissipated, you reach for a technology solution. Iris believes it has just the thing. The company launched a public beta to show off its technology this week. “We’re of course really excited with the first results,” says Anita Schjøll Brede, the company’s CEO. “But to be honest we’re running a marathon here. Our ultimate goal is an AI Scientist and we’re not done
More corals are dying and others are succumbing to disease and predators after the worst-ever bleaching on Australia's iconic Great Barrier Reef, scientists said Wednesday. A swathe of corals bleached in the northern third of the 2,300-kilometre (1,429-mile) long biodiverse site off the Queensland state coast died after an unprecedented bleaching earlier this year as sea temperatures rose. "In March, we measured a lot of heavily bleached branching corals that were still alive, but we didn't see many survivors this week," Andrew Hoey of the Australian Research Council Centre of Excellence for Coral Reef Studies at James Cook University said in a statement.
The labels on prescription testosterone will now carry a new warning about the serious health risks that have been linked with abuse of these products. The Food and Drug Administration (FDA) announced the new labels today (Oct. 25), saying that some people abuse testosterone drugs. For example, the agency said, athletes and body builders have been known to take doses that are higher than those prescribed, and to use testosterone together with other anabolic steroids.

Observing a pianist at a recital—converting musical notations into precisely timed finger movements on a piano—can be a powerful emotional experience. As a researcher of neuroscience and a pianist myself, I understand that the mastering of this skill not only takes practice, but also requires complex coordination of many different brain regions. Brain regions that are responsible for our hearing, sight, and movement abilities engage in an amazing symphony to produce music. It takes coordinating both hands and communicating emotionally with other players and listeners to produce the magical effect. The combination of such demands is likely to influence brain structures and their functions. In
"Everything should be made as simple as possible, but not simpler," said Albert Einstein, who managed to distill the relationship between mass, energy, and light into an equation so brief it could be text slang. CRISPR (Nature has a great overview here) builds ever-so-slightly off a strategy used by bacteria to fend off repeat attacks from viruses. In the human version, scientists use an RNA guide to direct an enzyme, Cas-9, to a specific point in any organism's DNA--where, like an eagle-eyed copy editor, the enzyme snips out an errant letter or sequence as if it were expunging a typo.

“What we tried to achieve was to build a material structure that would shrink when you heat it and expand when you cool it down,” Nicholas Fang, an associate professor of mechanical engineering at MIT, told Digital Trends. To achieve this, Fang and his colleagues created tiny, 3D-printed star-shaped structures — around the size of a single sugar cube — which rapidly shrink when subjected to extreme temperatures of 540-degrees Fahrenheit.
