Living with a female mouse can extend the reproductive life of a male mouse by as much as 20 percent, according to a new study. The results have significant implications for the maintenance of male fertility in wildlife, livestock and even human populations.

When an infection attacks, the body’s immune system sounds the alert, kills the invading germs and remembers the pathogen to protect against contracting the same type of infection again. Exactly how immunological memory develops is a mystery just beginning to be unveiled in an article in the journal Science.

With climate change is a global concern, it’s timely to consider how trees are faring on the highest mountain slopes and at the northern treeline. In such extreme environments, oddly contorted forms of pine, spruce, birch and fir are created by blasting winds and inhospitable soils.
Current research suggests that inflammation increases the risk of plaque rupture in atherosclerosis. Atherosclerosis is a disease of arterial blood vessels where fats, cholesterol, blood cells, and fibers form hardened plaques on the artery wall.

A team of physicists and engineers has demonstrated an optical device that filters two particles of light (or photons) based on the correlations between their polarisation that are only allowed in the seemingly bizarre quantum world. This so called “entanglement filter” passes the pair of photons only if they inhabit the same quantum state, without [...]
Whether the soundtrack of your youth was doo-wop or disco, new wave or Nirvana, psychology research shows that even just thinking about a particular song can evoke vivid memories of the past.

Biologists have identified a cellular mechanism in mutated “Indy” fruit flies that appears to reduce significantly the production of free radicals, which are blamed for contributing to the aging process.

Bioengineers have shown that small plastic disks impregnated with tumor-specific antigens and implanted under the skin can reprogram the mammalian immune system to attack tumors. The research — which ridded 90 percent of mice of an aggressive form of melanoma that would usually kill the rodents within 25 days — represents the most effective demonstration [...]

Researchers have created a precise biosensor for detecting blood glucose and potentially many other biological molecules by using hollow structures called single-wall carbon nanotubes anchored to gold-coated “nanocubes.”
