Adult human stem cells may offer the opportunity to use one of biomedical science's most promising technologies without the ethical dilemmas of embryonic cells.

Genetic elements that jump around the genome can influence brain circuitry, according to US researchers.

gene is involved in regulating the brain's dopaminergic reward pathway.

US researchers have evidence that damage to mammalian male fertility caused by transient exposure of embryos to endocrine-disrupting environmental toxins can be passed down to subsequent generations.1 "The endocrine disruptors appear to have altered the remethylation and permanently reprogrammed the germ line, that is, sperm," explains study coauthor Michael Skinner of Washington State University in Pullman.Skinner and colleagues exposed female rats in mid gestation to high doses of two endocrin

Applied Biosystems of Foster City, Calif., has released a MALDI-TOF/TOF instrument that, according to the company, offers a 10-fold increase in sensitivity over current models.

To map most of the genetic variation in the human genome, scientists need to look at several hundred thousand single nucleotide polymorphisms (SNPs) per individual.
