A new study analyzes the calorie content of 18 side dishes and entrees from national sit-down chain restaurants, 11 side dishes and entrees from national fast food restaurants and 10 frozen meals purchased from supermarkets. Researchers compared their results to the calorie content information provided to the public by the restaurants and food companies.

Software agents that play devil’s advocate and quarrel with each other may not sound like something you would want in your computer. But, say a team of researchers, argumentative agents promise faster, cheaper and more efficient online transactions.

The complete asexuality of a widespread fungus-gardening ant, the only ant species in the world known to have dispensed with males entirely, has recently been confirmed.

Many people dream of skiing off piste in deep virgin snow. But their dream would rapidly turn into a nightmare if they were to set off a slab avalanche. Researchers have now developed a remote triggering system for avalanche airbags.

Neuroscientists have forged an unlikely molecular union as part of their fight against diseases of the brain and nervous system, bringing together the herpes virus and a molecule known as Sleeping Beauty to improve gene therapy. The work has allowed scientists to reach a long-sought goal: shuttling into brain cells a relatively large gene that can remain on for an extended period of time.

Scientists have discovered a new molecular mechanism that permits the guidance of visual nerves towards the brain.

Mobile technologies, including the global system for mobile communication and the ZigBee short-range wireless data connection technology could be used to monitor and detect bushfires, according to new research.

Scientists have identified a gene underlying a disease that causes temporary paralysis of skeletal muscle. The finding, they say, illustrates how investigations of rare genetic diseases can drive insights into more common ones.

Charles Darwin spent eight years studying barnacles and their genitalia. In much less time than that, modern-day evolutionary biologists have confirmed one of Darwin's theories: that genitalia complexities in some male species have developed because they assist the male in "holding her securely."

Subjective cognitive impairment (SCI), the earliest sign of cognitive decline, is marked by situations such as when a person recognizes they can't remember a name like they used to or where they recently placed important objects the way they used to. A new study finds that healthy older adults reporting SCI are 4.5 times more likely to progress to the more advanced memory-loss stages of mild cognitive impairment or dementia than those free of SCI.
