Science fiction writers have long envisioned sailing a spacecraft by the optical force of the sun’s light. But, the forces of sunlight are too weak to fill even the oversized sails that have been tried. Now a team led by researchers at the Yale School of Engineering & Applied Science has shown that the force [...]

A comprehensive mouse model of inherited prion disease exhibits cognitive, motor and neurophysiological deficits that bear a striking resemblance to the symptoms experienced by patients with the human version of “mad cow disease,” Creutzfeldt-Jakob disease. The research, published in the journal Neuron, provides exciting insight into the mechanism of disease and may lead to the [...]

Researchers compared green and black tea to soda and orange juice in terms of their short- and long-term erosive effect on human teeth. The study found that the erosive effect of tea was similar to that of water, which has no erosive effect.

A new study shows that the current tuberculosis vaccine induces protective immunity against nine strains of the bacteria in mice indicating that strain-specific resistance may be uncommon.
A new Danish observatory on a remote island in the middle of the Atlantic Ocean will provide researchers with new knowledge about the mysterious irregularity of the Earth’s magnetic field known as the South Atlantic Anomaly.
How do people use emoticons, subject lines, and signatures to define how they want to be interpreted in email? The authors find that “a shift to email interaction requires a new set of interactional skills to be developed.” Unlike face-to-face conversations, email interactions leave out tone of voice, body-language and context, which can lead to [...]

Obesity gradually numbs the taste sensation of rats to sweet foods and drives them to consume larger and ever-sweeter meals, according to neuroscientists. New findings could uncover a critical link between taste and body weight, and reveal how flab hooks the brain on sugary food.

When mice that lack steroid receptor-2, a master regulator gene called a coactivator, fast for a day, their blood sugar levels plummet. If they go another day without food, they will die. The severity of the hypoglycemia was unexpected, according to an article in Science.

Researchers report that subjecting a common plastic to physical stress - which causes the plastic to flow - also dramatically increases the motion of the material’s constituent molecules, with molecular rearrangements occurring up to 1,000 times faster than without the stress.
