While scientists and physicians know what happens if you don’t get six to eight hours of shut-eye a night, investigators have long been puzzled about what controls the actual need for sleep. Researchers at the University of Pennsylvania School of Medicine might have an answer, at least in fruit flies. In a recent study of fruit flies, they identified a gene that controls sleep.
Paleontologists in 2005 hailed research that apparently showed that soft, pliable tissues had been recovered from dissolved dinosaur bones, a major finding that would substantially widen the known range of preserved biomolecules.
Cut off one finger from a salamander and one will grow back. Cut off two and two will grow back. It sounds logical, but how the salamander always regenerates the right number of fingers is still a biological mystery.
Seminal fluid contains protein factors that, when transferred from a male to a female at mating, affect reproductive success. This is true of many different animals, from crickets to primates.
Researchers at Durham, the RSPB and Cambridge University have found that birds such as the Cirl Bunting and Dartford Warbler are becoming more common across a wide range of habitats in Britain as temperatures rise.
Scientists from Queen Mary, University of London are helping to perfect a technique used to catch serial killers, by testing it on bumblebees.
A new study of DNA from ancient and modern chickens has shed light on the controversy about the extent of pre-historic Polynesian contact with the Americas.
Hundreds of insect species spend much of their time underwater, where food may be more plentiful. MIT mathematicians have now figured out exactly how those insects breathe underwater.
Fruit flies fine-tune their olfactory systems by recalibrating the sensitivity of different odor channels in response to changing concentrations of environmental cues, a new study has shown. Disable this calibration system, and flies have trouble finding a mate, the researchers found.
