Researchers suggest that the eccentricity of Saturn’s orbit around the sun may be responsible for the unusually uneven distribution of methane and ethane lakes over the northern and southern polar regions of the planet’s largest moon, Titan. On Earth, similar “astronomical forcing” of climate drives ice-age cycles.

Two prototype devices have been developed: one for efficient disinfection of healthy skin (e.g. hands and feet) in hospitals and public spaces where bacteria can pose a lethal threat; and another to shoot bacteria-killing agents into infested chronic wounds and enable a quicker healing process.
The use of antibiotic eye drops for conjunctivitis has increased by almost half since they became available over the counter at U.K. pharmacies in 2005.

Intervals of regional warmth and cold in the past are linked to the El Niño phenomenon and the so-called “North Atlantic Oscillation” in the Northern hemisphere’s jet stream, according to a team of climate scientists. These linkages may be important in assessing the regional effects of future climate change.

Researchers using functional magnetic resonance imaging to study brain activation have found that men and women respond differently to positive and negative stimuli, according to a new study.

New connections begin to form between brain cells almost immediately as animals learn a new task, according to a study in which researchers observed the rewiring processes that take place in the brain during motor learning.

Scientists have determined that a major change in the climate of the Sahara and Sahel region of North Africa facilitated early human migrations from the African continent. Among the key findings are that the Sahara desert and the Sahel were considerably wetter around 9,000, 50,000 and 120,000 years ago then at present, allowing for the [...]
