Study shows how Salmonella survives in environment

Scientists at the University of Liverpool have demonstrated how a single-celled organism, living freely in the environment, could be a source of Salmonella transmission to animals and humans.

Stem cell therapy may lead to treatment for deafness

Deafness affects more than 250 million people worldwide. It typically involves the loss of sensory receptors, called hair cells, for their "tufts" of hair-like protrusions, and their associated neurons.

Differences of sex and gender in mental illness

Why do women suffer from depression more often than men? Why does schizophrenia affect more men than women? Should men and women be treated differently for mental illness?

Human adult testes cells can become embryonic-like

Using what they say is a relatively simple method, scientists at Georgetown University Medical Center have extracted stem/progenitor cells from testes and have converted them back into pluripotent embryonic-like stem cells.

Coenzyme rare to bacteria critical to Mycobacterium tuberculosis survival

Coenzyme F420, a small molecule that helps certain enzymes transfer electrons, is found in microorganisms known as methane-producing archaea, some of which thrive in extreme environments.

Facial flushing after drinking alcohol could be a sign of esophageal cancer

There is growing evidence, say researchers in this week's PLoS Medicine , that people who experience facial flushing after drinking alcohol are at much higher risk of esophageal cancer from alcohol consumption than those who do not.

Alcohol-inducing flushing and esophageal cancer

There is growing evidence, say researchers in this week's PLoS Medicine, that people who experience facial flushing after drinking alcohol are at much higher risk of esophageal cancer from alcohol consumption than those who do not.

Scientists find molecular mechanisms linking sugar production and longevity

Johns Hopkins researchers have discovered a new energy-making biochemical twist in determining the lifespan of yeast cells, one so valuable to longevity that it is likely to also functions in humans.

Astrocytes help separate man from mouse

A type of brain cell that was long overlooked by researchers embodies one of very few ways in which the human brain differs fundamentally from that of a mouse or rat, according to researchers who published their findings as the cover story in the March 11 issue of the Journal of Neuroscience.

Gulf War veterans display abnormal brain response to specific chemicals

A new study by UT Southwestern Medical Center researchers is the first to pinpoint damage inside the brains of veterans suffering from Gulf War syndrome - a finding that links the illness to chemical exposures and may lead to diagnostic tests and treatments.

Cathepsin B increases apoptosis in fulminant hepatic failure

The traditional view is that hepatocyte necrosis is the main feature of fulminant hepatic failure, but increasing evidence implicates a dominant role for hepatocyte apoptosis in this pathogenesis.
