In times of starvation, cells tighten their belts: they start to digest their own proteins and cellular organs. The process - known as autophagy - takes place in special organelles called…

We learn a lot from genes but it turns out we can learn even more - like where you lived or even who you spent time with.   It just requires knowing where and how to look. Researchers from…

As we mark the 200th anniversary of Charles Darwin's birth, there is much focus on evolution in animals and plants. But new research shows that for the countless billions of tiniest creatures –…

A little more than a year after University of Wisconsin-Madison scientists showed they could turn skin cells back into stem cells, they have pulsating proof that these "induced" stem cells can indeed…

A multi-institutional team of researchers has reported the sequences for all of the 99 known strains of cold virus, nature's most ubiquitous human pathogen. The feat exposes, in precise detail, all…

Many of the world's cultural treasures are creations made of organic materials such as paper, canvas, wood and leather which, in prolonged warmth and dampness, attract mold, micro-organisms and…

The simple recipe scientists earlier discovered for making adult stem cells behave like embryonic-like stem cells just got even simpler. A new report in the February 6th issue of the journal Cell…

Monash Institute of Medical Research (MIMR) scientists have created Australia's first induced pluripotent stem (iPS) cell lines.   They have derived the cells from skin cells, and reprogrammed…

Nanotubes are often regarded as a precursor to nanocircuitry.  A group at UC San Diego has found that they work pretty well for transferring biological information, too.  Oh, et al. showed…

Researchers from Northwestern University's Feinberg School of Medicine appear to have reversed the neurological dysfunction of early-stage multiple sclerosis patients by transplanting their own…
