Tiny RNA molecule found to help create skin's protective barrier

Every minute, 30,000 of our outermost skin cells die so that we can live. When they do, new cells migrate from the inner layer of the skin to the surface of it, where they form a tough protective barrier.

Adult stem cell changes underlie Hutchinson-Gilford Progeria syndrome associated with accelerated aging

Adult stem cells may provide an explanation for the cause of a Hutchinson-Gilford Progeria Syndrome (HGPS), a rare disease that causes premature aging in children, according to researchers at the National Cancer Institute (NCI), part of the National Institutes of Health (NIH).

Springer launches 18,000 searchable online protocols in life sciences and biomedicine

Springer Science+Business Media (www.springer.com) has announced the release of Springer Protocols, a protocol database of more than 18,000 searchable online protocols in life sciences and biomedicine.

New insight into the fundamentals of Parkinson's disease

A single change in a protein may play a role in whether someone develops Parkinson's disease, say University of Florida Genetics Institute researchers writing in a recent issue of the Proceedings of the National Academy of Sciences.

New chemical tool kit manipulates mitochondria, reveals insights into drug toxicity

Why do nearly 1 million people taking cholesterol-lowering statins often experience muscle cramps? Why is it that in the rare case when a diabetic takes medication for intestinal worms, his glucose levels improve? Is there any scientific basis for the purported health effects of green tea?

Genetic defect causes immune deficiency and balance disorder

A genetic defect that causes a severe immune deficiency in humans may also produce balance disorders, according to a new study by researchers at the University of Iowa, The Jackson Laboratory and East Carolina University.

New way to grow blood vessels

Researchers at Dana-Farber Cancer Institute have found a previously unknown molecular pathway in mice that spurs the growth of new blood vessels when body parts are jeopardized by poor circulation.

Scientists shed light on long-distance signaling in developing neurons

A longstanding puzzle in neurodevelopment may have yielded up a key secret.

New key finding in neurodevelopment

A longstanding puzzle in neurodevelopment may have yielded up a key secret. A team led by scientists at Weill Cornell Medical College says they have determined how events at the very tips of the developing neuron's long, skinny axon affect gene transcription back in the cell's distant nucleus.

Oncoproteins double-team and destroy vital tumor-suppressor

Two previously unconnected cancer-promoting proteins team up to ambush a critical tumor suppressor by evicting it from the cell's nucleus and then marking it for death by a protein-shredding mechanism, a team led by scientists at The University of Texas M. D. Anderson Cancer Center reports in the Feb. 10 issue of Nature Cell Biology.

How a red blood cell loses its nucleus

Unlike the rest of the cells in your body, your red blood cells lack nuclei.

New clues about how cancer cells grow

Scientists in Switzerland are uncovering new clues about how cancer cells grow - and how they can be killed - by studying stem cells, 'blank' cells that have the potential to develop into fully mature or 'differentiated' cells and other scientists in UK have made a breakthrough in understanding the cause of the most common form of childhood cancer, acute lymphoblastic leukaemia (ALL).
