Sperm stem cells research provides exciting findings

New experiments that prevented rat sperm stem cells from changing permanently into sperm have brought researchers one step closer to coaxing such cells to behave like embryonic stem cells, capable of growing into many other types of cells in the body.

Study of how bacteria change their metabolic networks

Bacteria feel pressures to evolve antibiotic resistance and other new abilities in response to a changing environment, and they react by 'stealing' genetic information from other better-adapted types of bacteria, according to research published in Nature Genetics.

New gene linked to schizophrenia and depression

A Scots-led medical research team has identified a new gene linked to major mental illness that links back to a previously discovered gene known to increase the risk of schizophrenia and depression.

New genes that regulate longevity

In an effort to understand the molecular mechanisms that control aging, Howard Hughes Medical Institute researchers and their colleagues have now uncovered 10 new genes that regulate longevity in yeast. The studies also suggest a new model for how aging is slowed when caloric intake is restricted.

Plant extract forskolin may lead to leukemia treatment

Scientists here have identified a new pathway in the progression of chronic myelogenous leukemia (CML). They also discovered that an extract from the root of a common ornamental plant can suppress the process.

Lack of aggressive treatment for clogged leg blood vessels means missed heart attack prevention opportunity

Despite the fact that clogged arteries in the legs usually mean clogged arteries near the heart, doctors often fail to give heart-protecting drugs to people with severe leg blood vessel blockages, a new University of Michigan-led study finds.

Vietnamese researchers say bird flu already resisant to Tamiflu

Scientists in Vietnam are concerned that the deadly bird flu may have infected two more people, and they suspect the virus may have mutated into a more dangerous form which could spread in mammals, and cause outbreaks in poultry.

Better understanding of cancer cachexia

New research shows that a wasting condition responsible for nearly a third of all cancer deaths involves the loss of an essential muscle protein that is also lost in people with muscular dystrophy.

Edifoligide no better than placebo for clogged veins

A new drug, edifoligide, designed to prevent the clogging of veins used in coronary bypass surgery was no more effective than a placebo, according to the results of a Phase III clinical trial led by researchers at Duke Clinical Research Institute (DCRI).

Nerve-cell dendrites splice messenger RNA

Researchers at the University of Pennsylvania School of Medicine have discovered that nerve-cell dendrites have the capacity to splice messenger RNA (pre-mRNA), a process once believed to only take place in the nucleus of cells.
