It’s a clear, colorless disk about 5 inches in diameter that bends and twists like a playing card, with a lattice of more than 20,000 nanotube transistors capable of high-performance electronics printed upon it using a potentially inexpensive low-temperature process.
By applying an old theory that has been used to explain water flow through soil and the spread of forest fires, researchers may have an answer to a perplexing ecological and evolutionary problem: why locusts switch from an innocuous, solitary lifestyle to form massive swarms that can devastate crops and strip fields bare.

New research in an animal model suggests that a diet high in inorganic phosphates, which are found in a variety of processed foods including meats, cheeses, beverages and bakery products, might speed growth of lung cancer tumors and may even contribute to the development of those tumors in individuals predisposed to the disease.

Contact with nature has long been suspected to increase positive feelings, reduce stress, and provide distraction from the pain associated with recovery from surgery. Now, research has confirmed the beneficial effects of plants and flowers for patients recovering from abdominal surgery.

Patients with diabetes at the time of a cancer diagnosis have an increased risk of death compared to patients without diabetes, according to a meta-analysis of studies.
Over the last 60 years, ever-smaller generations of transistors have driven exponential growth in computing power. Could molecules, each turned into miniscule computer components, trigger even greater growth in computing over the next 60?

Males that produce sperm packages that can penetrate deep into the skin. Females with bellies full of stored sperm. Males that seriously injure the females during mating. This is just a selection of the bizarre reproductive techniques that marine biologist Henk-Jan Hoving has discovered with different species of deep-ocean squid.

Neanderthal extinction was principally a result of competition with Cro-Magnon populations, rather than the consequences of climate change, according to a new study.

Scientists have succeeded in reversing brain birth defects in animal models, using stem cells to replace defective brain cells. The work involved using mouse embryonic neural stem cells, which migrate in the brain, search for the deficiency that caused the defect, and then differentiate into becoming the cells needed to repair the damage.
