Study: Rain forest insects eat no more tree species than temperate counterparts
A study initiated by University of Minnesota plant biologist George Weiblen has confirmed what biologists since Darwin have suspected -- that the vast number of tree species in rain forests accounts for the equally vast number of plant-eating species of insects.

A test used to detect prostate cancer can also help doctors know when treatment is working.

Sulfur signature changes thoughts on atmospheric oxygen
Ancient sediments that once resided on a lake bed and the ocean floor show sulfur isotope ratios unlike those found in other samples from the same time, calling into question accepted ideas about when the Earth's atmosphere began to contain oxygen, according to researchers from the U.S., Canada and Japan.

Tight-knit family: Even microbes favor their own kin
New research in this week's issue of Nature finds that even the simplest of social creatures -- single-celled amoebae -- have the ability not only to recognize their own family members but also to selectively discriminate in favor of them.

Viruses can jump between primates and humans, researchers warn
Viruses that jump the species barrier between monkeys and humans can harm both people and animals, and we should take steps to reduce the risk of virus transmission.

Oxygen deprived brains repaired and saved
Scientists from Melbourne's Howard Florey Institute have found special proteins that protect the brain after it has been damaged by a lack of oxygen, which occurs in conditions such as stroke, perinatal asphyxia, near-drowning and traumatic brain injury.

Dads want flexibility, not shorter working hours
Being a father has little effect on men's working patterns, in spite of the fact that they cut back their working hours for a short time after a new child is born, according to Economic and Social Research Council funded research at the University of Bristol. is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to
