Researchers have devised a new simulation technique that reliably predicts the structure and behavior of different materials, in order to accelerate the development of next-generation batteries for a wide range of applications.
Rosetta’s lander Philae will target Site J, an intriguing region on Comet 67P/Churyumov–Gerasimenko that offers unique scientific potential, with hints of activity nearby and minimum risk to the lander compared to the other candidate sites.
Things can go downhill fast when a patient has sepsis, a life-threatening condition in which bacteria or fungi multiply in a patient's blood— often too fast for antibiotics to help. A new device inspired by the human spleen may radically transform the way doctors treat sepsis.
New research shows that schizophrenia isn’t a single disease but a group of eight genetically distinct disorders, each with its own set of symptoms. The finding could be a first step toward improved diagnosis and treatment for the debilitating psychiatric illness.
An anti-addiction drug used to fight the nation's heroin and painkiller abuse epidemics poses a threat to young children who accidentally swallow relatives' prescriptions, a federal study says. Some children have died.
Gilead Sciences says it has reached a deal with several generic drugmakers to produce cheaper versions of its popular, expensive hepatitis C drug Sovaldi for use in developing countries.
The Asian monsoon already existed 40 million years ago during a period of high atmospheric carbon dioxide and warmer temperatures, reports an international research team. Scientists had thought the climate pattern known as the Asian monsoon began 22 to 25 million years ago as a result of the uplift of the Tibetan Plateau and the Himalaya Mountains.
Researchers have identified a mechanism by which wrinkles may have formed in ancient rocks. Based on this mechanism, they posit that such fossilized features may be a vestige of microbial presence— in other words, where there are wrinkles, there must have been life.
Based on models and observations, climate scientists have devised a simplified formula to describe one of the consequences of climate change: regions already marked by droughts will continue to dry out in the future climate. Regions that already have a moist climate will experience additional rainfall. However, this formula is less universally valid than previously assumed.
A comprehensive look at how tiny particles in a lithium ion battery electrode behave shows that rapid-charging the battery and using it to do high-power, rapidly draining work may not be as damaging as researchers had thought– and that the benefits of slow draining and charging may have been overestimated.
Muscular dystrophies are a group of muscle diseases characterized by skeletal muscle wasting and weakness. Mutations in certain proteins, most commonly the protein dystrophin, cause muscular dystrophy in humans. Now, a potential way to treat muscular dystrophy directly targets muscle repair instead of the underlying genetic defect that usually leads to the disease.
New sea lamprey studies have shown remarkably conserved gene expression patterns in jawless versus jawed vertebrates. The finding means that the genetic program used by jawed vertebrates— including us— was up and running ages before a vertebrate ever possessed a recognizable face.
Parts of the flag that inspired America’s national anthem were snipped off and handed out as mementos. The Smithsonian has been reacquiring some of those fragments and adding to their collection, verifying them through high-tech methods.
Sixteen years after scientists found the genes that control the circadian clock in all cells, researchers have discovered the mechanisms responsible for keeping the clock in sync. The find has implications for the development of drugs for various diseases such as cancers and diabetes, as well as conditions such as metabolic syndrome, insomnia, seasonal affective disorder, obesity and even jetlag.
The central mystery of quantum mechanics is that small chunks of matter sometimes seem to behave like particles, sometimes like waves. Now, new math explains the dynamics of fluid systems that mimic many peculiarities of quantum mechanics.
