A newly discovered transmembrane protein called "Wurst" (sausage) appears to play a decisive role in breathing – possibly in all animals, from flies to human beings. This insight is reported by…

Researchers have discovered the molecule that links spontaneous physical activity and food intake in mice. Scientists from the European Molecular Biology Laboratory (EMBL)say Bsx is the molecular…

Researchers tied the accumulation of the toxic brain protein beta-amyloid to Alzheimer's disease, according to a new study. "Our findings show that beta-amyloid is associated with brain dysfunction—…

The Sleeping Beauty tranposon (SB-Tn) system, a gene therapy technology that avoids the pitfalls of transferring genes with viruses, shows promise in laboratory experiments for correcting the gene…

A new report in the journal Cell confirms the existence of some apparently uncommitted stem cells amongst cells responsible for generating the bulging biceps of body builders and the rippling abs of…

It is easy to observe that many networks naturally divide into communities or modules, where links within modules are stronger and denser than those across modules – like the way people from the same…

Matthew Tyska, Ph.D., recalls being intrigued, from the first day of his postdoctoral fellowship in 1999, with a nearly 30-year-old photograph. It was an electron micrograph that showed the internal…

A recent paper highlights experimental research in evolution and artificial selection, providing insight into how organisms adapt to changing environmental conditions and fluctuations. In this month'…

For the first time anywhere, a researcher at the Hebrew University of Jerusalem has succeeded in observing in vivo the generation of neurons in the brain of a mammal. Magnified photo shows division…

Effector proteins are the bad guys that help bacterial pathogens do their job of infecting the host by crippling the body's immune system. In essence, they knock down the front door of resistance and…
