John Hauptman stood before an international gathering of particle physicists and announced he had another idea.

One that was different. One that was simpler. And best of all, one that he was sure would work.The 4th Concept detector would eliminate the iron surrounding most particle detectors and would be about one-tenth the mass of other detectors. Credit: Iowa State University

Gay and bisexual men may be at far higher risk for eating disorders than heterosexual men, according to a study conducted at Columbia University. In the first population-based study of its kind, the researchers found that gay and bisexual men have higher rates of eating disorders. The findings are reported in the April 2007 issue of International Journal of Eating Disorders.

A drug under study to treat various cancers selectively kills cancer cells because of its affinity for a modified version of a critical heat shock protein they contain, researchers have found.

They found in cancer a modified version of heat shock protein 90, or hsp90, which like most heat shock proteins, promotes cell survival.

Maybe not, but they get hot flashes related to genital changes.

Men who have undergone chemical castration for conditions such as prostate cancer experience hot flashes similar to those experienced by menopausal women, says a new study in Psychophysiology.

Using a technique called sternal skin conductance, doctors were able to positively identify hot flashes in males, a positive step toward providing therapy for those patients in need.

Research finds calorie-dense dessert recipes printed in major newspapers across the country may be contributing to obesity in large cities. The study, conducted by researchers at Marshfield Clinic Research Foundation, Marshfield, Wis., is published in the latest issue of the Wisconsin Medical Journal (Volume 106, No. 2).

The regions studied were in the West (Los Angeles, Denver, Portland), Midwest (Milwaukee, Detroit, Kansas City), South (Washington D.C., Dallas, Jacksonville) and the Northeast (New York, Philadelphia, Boston).

Immune cells that are the body’s front-line defense don’t necessarily rest quietly until invading bacteria lock onto receptors on their outside skins and rouse them to action, as previously thought. In a new paper, University of Michigan scientists describe their findings that bacteria can barge inside these guard cells and independently initiate a powerful immune response.

Researchers have successfully applied X-ray scattering techniques to determine how dissolved metal ions interact in solution.

Dutch researcher Laura Brandán Briones, that's who.

She improved both the tests and the method to determine the reliability of the tests. This means, for example, that washing machines and coffee machines can be tested far better before they are launched on the market.

Brandán Briones made several considerable improvements. First of all she made it possible to include the factor 'time' in the testing. Not only can it be determined if coffee actually comes out of the machine but also how long that takes.

Human bone marrow has been used to create early-stage sperm cells for the first time, a scientific step forward that will help researchers understand more about how sperm cells are created.

People who inherit two mutant copies of any one of about 12 genes that make the proteins of the Fanconi Anemia (FA) pathway develop FA, which is characterized by increased incidence of cancer and bone marrow failure, among other things.

However, individuals with just a single mutant copy of one of these genes are also at increased risk of developing cancer. This occurs when the remaining "good" copy of the gene becomes mutated in a specific cell type, allowing that cell type to form a tumor.
