Human embryonic stem cell lines accumulate changes in their genetic material over time

The findings do not limit the utility of the cells for some types of research or for some future clinical applications, the researchers say, but draw attention to the need to closely monitor stem cell lines for genetic changes and to study how these alterations affect the cells' behavior.

Researchers discover one of the reasons why melanoma is so ruthless

About 60,000 Americans will be diagnosed with melanoma this year, says the American Cancer Society, and 10,000 of those cases will be fatal. If not caught in the early stages, melanoma can be a particularly virulent form of cancer, spreading through the body with an efficiency that few tumors possess.

UK fertility specialist and broadcaster says embryonic stem cell research promises are hyped up

According to a well known fertility specialist and broadcaster in the UK, the promise of embryonic stem cell research has been oversold by scientists.

Lack of exposure to dirt and common viral infections among children could be behind the rise in the levels of asthma

Scientists believe that knowing exactly which type of dirt provides the best 'education' for the immune system, could be key to providing new treatments for diseases such as asthma.

Overall genome landscape between chimps and humans can be attributed to large segmental duplications

A study comparing the genomes of both humans and chimpanzees has found that much of the genetic difference between the two species came about in events called segmental duplications, in which segments of genetic code are copied many times in the genome.

New key evidence supports claims that some types of cancer originate with defects in stem cells

Scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg and the Institute of Biomedical Research of the Parc Científic de Barcelona (IRB-PCB) have now added key evidence to claims that some types of cancer originate with defects in stem cells.

Potential new way to fight HIV

Researchers have confirmed for the first time the benefit of an innate defense system present in the few patients who remain healthy after years of infection with HIV despite receiving no treatment, according to an article published in the September edition of the Journal of Virology.

Study points to link to neurodegenerative disease target

A University of California - San Francisco (UCSF) study has found that a specific signaling link between neurons and muscles in the fruit fly is essential for keeping the insect's nervous system stable.

African-American women with mitochondrial DNA variant are at increased risk of breast cancer

African-American women who carry the 10398A mitochondrial DNA allele are 60 percent more likely to develop invasive breast cancer than African-American females without that genetic marker, according to research published in the September 1 issue of "Cancer Research."

Toluidine blue dye reveals oral cancers

A team of Canadian scientists may have discovered a way to use a simple dye as a litmus test to identify abnormal areas of the mouth that may become cancers.

Men with breast cancer gene at risk of pancreatic and prostate cancers

The very same genetic mutation which has been previously linked to the development of breast cancer in women may also be responsible for some cancers in men.

New lotion repairs sun damaged skin

Scientists in the U.S. have developed a lotion which repairs sun damaged skin.

Human Y chromosome stays intact while chimp Y loses genes

The human and the chimpanzee Y chromosomes went their separate ways approximately 6 million years ago. But ever since this evolutionary parting, these two chromosomes have experienced different fates, new research indicates.

Mutation in the BRAC2 breast cancer gene may also increase the risk of bone and throat cancers

A genetic mutation implicated in an increased risk of breast and ovarian cancers also significantly increases the risk of pancreatic and prostate cancers in men, finds research in the Journal of Medical Genetics.

More than 15 percent of our genes are mobilized to defend against microbial attacks

The body's overwhelming genetic defense, which has implications for the survival of patients who are severely burned or injured, was revealed in a sweeping analysis of gene activity in volunteers who were injected with a bacterial product that temporarily created flu-like symptoms.

When it comes to inflammation, too much of a good thing can be deadly

In some severely injured patients, this normal healing process can develop into a lethal, whole-body response, including bloodstream infection (sepsis) and multiple organ failure. How and why inflammation turns from healing to harming is still mysterious, so doctors can't accurately predict how each injured patient will fare.

Charles Darwin was right and chimp gene map proves it

According to scientists who have mapped the complete chimp genome and compared it to the human gene map, there is little genetic difference between humans and chimps, but those differences count for a lot.

Hutchinson-Gilford progeria syndrome in children may be helped by cancer drugs

Children who suffer from a rare disease called progeria, which accelerates aging and often kills patients when they are in their teens, may possibly be helped by drugs being developed to treat cancer.

Unique Internet test to test genetic disposition to depression

The team, based at the Neuroscience and Psychiatry Unit (NPU), in the Faculty of Medical and Human Sciences, has set up a website (www.newmood.co.uk) where would-be volunteers can see how prone they may be to depression by identifying the emotions on people's faces and taking a gambling test.
