Asymmetric cell divisions are essential for skin development

It took almost 10 years for Elaine Fuchs, Ph.D., a Howard Hughes Medical Institute investigator at Rockefeller University, to find a postdoctoral fellow who shared her curiosity for the direction of cell divisions in the skin.

Mutations in the targets of designer drugs critically influence their effectiveness

Two designer cancer drugs differed dramatically in a laboratory test comparing their ability to shut down a mutant, overactive growth signal in lung cancer cells, reports a team headed by scientists at the Dana-Farber Cancer Institute.

Slower care for heart attack patients treated after hours and on weekends

Heart attack patients treated with primary percutaneous intervention (PCI) at hospitals after hours and on weekends wait longer to receive clot busters and other treatments and have a higher risk of death than those treated during regular hospital hours

First clear evidence that olfaction is uniquely a "dual" sense

In the August 18, 2005, issue of Neuron, researchers report that the smell of chocolate activated different brain regions according to whether the odor was introduced into the olfactory system through the mouth or through the nose.

C. elegans has similar virus-fighting mechanism as humans and can be used in research

Researchers at the University of California, Riverside have discovered that a simple worm, called C. elegans, makes an excellent experimental host for studying some of the most virulent viruses that infect humans.

Loss of a gene called p63 accelerates aging in mice

Researchers have discovered that the loss of a gene called p63 accelerates aging in mice. Similar versions of the gene are present in many organisms, including humans. Therefore, the p63 gene is likely to play a fundamental biological role in aging-related processes.

Women who take oral contraceptives can counteract bone loss by increasing calcium in their daily diet

Women who take oral contraceptives can counteract bone loss by making sure they have enough calcium in their daily diet, especially early in life, according to Purdue University research.

Stem Cell Sciences to commercialise breakthrough in neural stem cell technology

Stem Cell Sciences has announced that it has an exclusive license to a new patented technology to derive and grow neural stem cells. This technology has been licensed from the University of Edinburgh.

Analytical tool to help detect cancer

Scientists have long used ultra-fine glass tubes known as capillaries to analyze the chemical makeup of substances. Called capillary electrophoresis, or CE, the method applies high voltage to the capillaries, and by measuring the rate that the various materials move through the capillaries, researchers are able to identify individual compounds.

Gene therapy success for the treatment of congenital muscular dystrophy (CMD) in mice

Researchers from the University of Pittsburgh report the first study to achieve success with gene therapy for the treatment of congenital muscular dystrophy (CMD) in mice, demonstrating that the formidable scientific challenges that have cast doubt on gene therapy ever being feasible for children with muscular dystrophy can be overcome.

Complications from angioplasty much lower among patients whose doctors perform a large number of those procedures each year

Before patients get their clogged heart arteries re-opened, they may want to ask their doctor just how many such procedures he or she has done, a new study finds. The answer may make a big difference in each patient's risk of suffering a major setback before leaving the hospital.

Immune system more concerned with damage detected than foreign invaders, such as viruses

A well-respected researcher who is now a chief of an immunology laboratory of the National Institutes of Health (NIH) has rocked the boat in the past few years for the experts in the understanding of the autoimmune system.

Combined gene therapy eliminates glioblastoma multiforme in lab studies

Despite aggressive treatment, glioblastoma multiforme (GBM) - the most common and deadly of brain cancers - usually claims the lives of its victims within six to 12 months of diagnosis. Because GBM is so aggressive, the disease has been the target of a number of laboratory and clinical studies investigating the effectiveness of gene therapy to deliver novel therapies to the brain.

MiRNA is opening up a whole new way of understanding carcinogenesis

Scientists mining vast, largely unexplored regions of the human genome have identified a small handful of mini-molecules that play a major role in the development of cancer and perhaps many other diseases.

Violent online games appear not to cause any substantial real-world aggression

Results from the first long-term study of online videogame playing may be surprising. Contrary to popular opinion and most previous research, the new study found that players' "robust exposure" to a highly violent online game did not cause any substantial real-world aggression.

Early menstruation is not by itself a risk factor for later obesity

Although overweight girls are more likely to start their periods earlier than their peers who are at or below normal weight, early menstruation is not by itself a risk factor for later obesity, according to a long-term study released this week.
