Positional cloning is a genetic mapping technique used to pinpoint the location of specific traits of interest, such as disease-causing genes or mutations, within the genome. Very simply, this map-…

A research team has discovered a molecular "rheostat" in the brain's appetite control center that may provide new insights into obesity, which is at epidemic levels in this country. The discovery of…

Acute kidney injury often arises after major surgery because the kidneys can be deprived of normal blood flow during the procedure. The use of contrast media, or dyes, can contribute to this problem…

Sometimes the whole is greater than the sum of its parts, said Aristotle. That certainly applies to biology, where molecular motions in living systems have a macroscale effect - such as large muscles…

A recently published study offers new clues about the evolution of the immune system in European populations of the plant Arabidopsis thaliana and the underlying genetic mechanisms associated with…

There is a lot of talk about increasing longevity but 50 years of increasing frailty, doctor visits and overall decline is not really an improvement over 30 years of it. A new study shows that by…

Some groups want to label foods that contain anything created with modern genetic modification. Yet the previous generation of genetically modified foods, using mutagenesis, can be labeled…

A new species of dinosaur has turned out not to be a dinosaur at all, it is instead one of the large reptiles that lived before dinosaurs took over the world. But like many dinosaurs, it looked…

Most dogs and most humans get along well now and anthropological explanations are that selective selection is the reason; wolves that were not a threat were not killed and over time the agreeable…
