Attractive women want it all!

Although many researchers have believed women choose partners based on the kind of relationship they are seeking, a new study from The University of Texas at Austin reveals women's preferences can be influenced by their own attractiveness.

Breast cancer gene carriers' risk 'amplified' by additional genes

Many women with a faulty breast cancer gene could be at greater risk of the disease due to extra 'risk amplifying' genes, according to research published in the American Journal of Human Genetics today.

Natural biomedicines from the ocean

With the number of terrestrial sources that yield novel treatments for human disease decreasing year by year, the oceans have been tapped as a promising resource for discovering new natural biomedicines.

Neuronal regulators offer potential targets for cancer

Being too brainy can be a bad thing in a junior high cafeteria, where the social hierarchy favors other traits. "Braininess" also causes problems for cells.

More efficient gene targeting improves prospects for gene therapy

The Nobel prize-winning MRC scientist Sir Aaron Klug and a team from an American company, Sangamo BioSciences, have announced a new way to target genes that may revolutionise medical research and pave the way for new treatments.

Disruption of the Contactin 4 gene on chromosome 3 may be linked to autism spectrum disorder

Eli Hatchwell, M.D., Ph.D., Associate Professor of Pathology at Stony Brook University Medical Center, and colleagues have found that a disruption of the Contactin 4 gene on chromosome 3 may be linked to autism spectrum disorder (ASD).

Millionaire leaves millions for research into motor neuron disease

A self-made millionaire Peter Goodenough who died from motor neuron disease (MND) left more than $6 million to the University's Queensland Brain Institute (QBI) to help find a cure for MND.

Survival mechanism of T lymphocytes uncovered

When an individual is challenged by a virus, a bacterium or any other infectious agent, several classes of white blood cells are being activated in order to fight the invasion.

Past child abuse plus variations in gene result in potent PTSD risk for adults

A traumatic event is much more likely to result in posttraumatic stress disorder (PTSD) in adults who experienced trauma in childhood - but certain gene variations raise the risk considerably if the childhood trauma involved physical or sexual abuse, scientists have found.

New method to determine the “selective signature” of a gene

Scientists at MIT have come up with a mathematical approach for analyzing a protein simultaneously in a set of ecologically distinct species to identify occurrences of natural selection in an organism's evolution.

$Variants of the gene LRP5 associated with increased risk of bone fractures, low bone mineral density$

Variants of the gene LRP5 associated with increased risk of bone fractures, low bone mineral density

Results from a large study indicate that variants of the gene LRP5 are associated with a significant increase in the risk of fractures, by up to 20 percent, and lower levels of bone mineral density in the spine and hip, according to a study in the March 19 issue of JAMA, a theme issue on Genetics and Genomics.

Family communication impacts attitude about genetic counseling/testing for breast cancer

Whether or not relatives talk about the family's history of cancer significantly impacts attitudes and knowledge about genetic counseling and testing for those at moderate risk of developing breast cancer, according to a new preliminary study presented today at the American Society for Preventive Oncology meeting in Bethesda, Md.

Psychological stress resulting from the traumatic stress may damage this brain

Individuals who experience military combat obviously endure extreme stress, and this exposure leaves many diagnosed with the psychiatric condition of post-traumatic stress disorder, or PTSD.

Discovery alters long standing concept of fixed protein structure

The thousands of proteins found in nature are simply strings of amino acids, assembled by genes, and scientists have long believed that they automatically fold themselves into uniquely fixed, 3-dimensional shapes to fire the engine of life.

Zebrafish enables cell regeneration studies to help understand, treat human disease

One aquarium fish's uncanny ability to regenerate essentially any cell type has given scientists a way to mimic cell loss that occurs in diseases such as Parkinson's and diabetes then watch how the fish make more of them.

Inbred Romanian community provides insight into genetic factors associated with vitiligo

An isolated, inbred Romanian community has a higher than average frequency of the skin disease vitiligo and other autoimmune diseases, suggesting a genetic variation that may indicate susceptibility to the condition in a broader population, according to a report in the March issue of Archives of Dermatology, one of the JAMA/Archives journals.

London's HIV epidemic was driven by clusters of sexual contacts

The rapid growth of the HIV/AIDS epidemic in London during the late 1990s was driven in part by transmission of the AIDS virus within clusters of sexual contacts, with individuals frequently passing the virus to others within months after becoming infected themselves, according to research published in PLoS Medicine by Andrew Leigh Brown and colleagues at the University of Edinburgh and London's Chelsea and Westminster Hospital.
