The Framingham and National Cholesterol Education Program tools do not accurately predict coronary heart disease, according to a new study.
If a specific butterfly anti-sex scent is coupled with a pleasant experience, then parasitic wasps are able to develop long-term memory and respond to this scent that they do not instinctively recognize. After successfully ‘hitch-hiking’ with a mated female cabbage white butterfly and parasitizing her eggs, the parasitic wasps are able to remember the route [...]

Researchers are reporting discovery of abnormal proteins in the saliva of autism patients that could eventually provide a clue for the molecular basis of this severe developmental disorder and could be used as a biomarker for a subgroup of patients with autism spectrum disorders (ASD).

If you leave it up to the rats, New York City beats New Orleans any day. Researchers have invented a novel way to test urban designers’ city plans. Instead of using humans as guinea pigs, the scientists went to their nearby zoo and enlisted lab rats to determine the functionality of theoretical and existing plans.
A new study sheds light on a little understood biological process called quiescence, which enables blood-forming stem cells to exist in a dormant or inactive state in which they are not growing or dividing. According to the study’s findings, researchers identified the genetic pathway used to maintain a cell’s quiescence, a state that allows bone [...]

All the genes that the exotic Tasmanian Tiger inherited only from its mother will be revealed in a new article. The research marks the first successful sequencing of genes from this carnivorous marsupial, which looked like a large tiger-striped dog and became extinct in 1936. The research also opens the door to the widespread, nondestructive [...]

Both the developing brain and the aging brain can suffer from lead exposure. For older people, a buildup of lead from earlier exposure may be enough to result in greater cognitive problems after age 55, according to a follow-up study of adults exposed to lead at work.
