In the Mesozoic Era, 70 million years before birds first conquered the skies, pterosaurs dominated the air with sparrow- to Cessna-sized wingspans. Researchers suspected that these extinct reptiles sustained flight through flapping, based on fossil evidence from the wings, but had little understanding of how pterosaurs met the energetic demands of active flight.
For centuries, animals have been our first line of defense against toxins. A canary in a coalmine served as a living monitor for poisonous gases. Scientists used fish to test for contaminants in our water. Even with modern advances, though, it can take days to detect a fatal chemical or organism. Until now. Working in [...]

Researchers have created hybrid carbon nanotube metal oxide arrays as electrode material that may improve the performance of lithium-ion batteries.
Scientists have discovered a mechanism in liver metabolism that is responsible for pathologically elevated blood fat levels found in severe metabolic disorders. Mice suffering from metabolic syndrome or type 2 diabetes produce only small amounts of a molecule called LSR in the liver. As a result, only small amounts of fat are transported from the [...]
Materials scientists have put a new “twist” on carbon nanotube growth. The researchers found nanotubes grow like tiny molecular tapestries, woven from twisting, single-atom threads. The research finds a direct relationship between a nanotube’s “chiral” angle — the amount it’s twisted — and how fast it grows.

While U.S. intelligence officials have spent more than seven years searching fruitlessly for Osama bin Laden, geographers say they have a good idea of where the terrorist leader was at the end of 2001 — and perhaps where he has been in the years since.
A researcher finds a clue to the calcification process by studying how a genetic mutation in rats makes them resistant to poison but also leaves them susceptible to arterial calcification and, potentially, osteoporosis.
European food companies already use nanotechnology in consumer products, but few voluntarily inform consumers. “The promise of nanotechnology,” a Dutch scientist said, “is that it could allow re-engineering ingredients to bring healthy nutrients more efficiently to the body while allowing less-desirable components to pass on through.”

A national panel of national pain management experts has published the first comprehensive, evidence-based clinical practice guideline to assist clinicians in prescribing potent opioid pain medications for patients with chronic non-cancer pain.
