About eight percent of human genetic material comes from a virus and not from our ancestors, according to a new study. The research shows that the genomes of humans and other mammals contain DNA derived from the insertion of bornaviruses, RNA viruses whose replication and transcription takes place in the nucleus.

Researchers have found in animal experiments that an antidepressant developed over 40 years ago can blunt and even reverse the muscle enlargement and weakened pumping function associated with heart failure.

Researchers have developed a novel mathematical model that predicts the spread of the H1N1 virus on long airplane flights could be significant, particularly if the infected individual travels in economy class.
Amid concerns regarding terrorists targeting airliners using weapons less detectable by traditional means, the Transportation Security Administration (TSA) is ramping up deployment of whole body scanners at security checkpoints in US airports. These systems produce anatomically accurate images of the body and can detect objects and substances concealed by clothing.
Researchers have found that pre-term infants exposed to thirty minutes of Mozart’s music in one session, once per day expend less energy — and therefore need fewer calories to grow rapidly — than when they are not “listening” to the music.

The discovery of fossil footprints from early backboned land animals in Poland leads to the sensational conclusion that our ancestors left the water at least 18 million years earlier than previously thought.

Researchers have discovered a previously unsuspected link between two different genetic pathways which suppress the growth of cancer tumors. This breakthrough, they say, could lead to new treatments for some of the deadliest and most intractable forms of cancer; including prostate cancer, brain cancer and melanoma.

Biologists have developed an efficient way to genetically modify human embryonic stem cells. Their approach, which uses bacterial artificial chromosomes to swap in defective copies of genes, will make possible the rapid development of stem cell lines that can both serve as models for human genetic diseases and as testbeds on which to screen potential [...]
