The smell of death proves to be an ancient warning signal to safeguard against predators and disease contagion. Researchers found that corpses of animals, from insects to crustaceans, all emit the same death stench produced by a blend of specific fatty acids.

Researchers have discovered a molecular circuit involving the oxygen-carrying component of hemoglobin — heme — that helps maintain proper metabolism in the body, providing new insights into metabolic disorders such as obesity and diabetes. This happens through a molecular pathway that allows the cell to monitor and adjust internal heme levels via Rev-erb±, creating more [...]
A new study suggests computers are now better at lip-reading than humans. Researchers found that an automated system significantly outperformed human lip-readers — scoring a recognition rate of 80 per cent, compared with only 32 per cent for human viewers on the same task.
While smoking cigarettes appears to significantly increase a person’s risk of developing multiple sclerosis, using Swedish snuff does not, according to a new study.

A wide-ranging study of big cat skulls has shown that tigers have bigger brains, relative to their body size, than lions, leopards or jaguars.
Encouraging reports are now emerging from various clinical trials of 2009 H1N1 influenza vaccines, conducted by various vaccine manufacturers. Additional companies are expected to announce their preliminary trial results shortly. The early data from these trials indicate that 2009 H1N1 influenza vaccines are well tolerated and induce a strong immune response in most healthy adults [...]
Scientists have found a rare species of algae that is tolerant of stressful environmental conditions and that proliferated in Caribbean corals when the corals’ more-sensitive algae were being expelled during the sea-temperature warming of 2005. The research is one of the first times that anyone has had the opportunity to conduct a community-wide study of [...]
Scientists in Switzerland have shown that short strands of ribonucleic acid (RNA) which regulate protein production are themselves also regulated. This additional layer of regulation opens up new perspectives for therapeutic approaches.
