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).

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.

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.

Researchers Ilan H. Meyer, PhD, associate professor of clinical Sociomedical Sciences at the Mailman School of Public Health and principal investigator, and Matthew Feldman, PhD, of the National Development and Research Institutes and first author, surveyed 516 New York City residents; 126 were straight men and the rest were bisexual men and women.

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.

For the growing number of people with diminished immune systems - cancer patients, transplant recipients, those with HIV/AIDS - infection by a ubiquitous mold known as Aspergillus fumigatus can be a death sentence.

The fungus, which is found in the soil, on plant debris and indoor air, is easily managed by the healthy immune system. But as medical advances contribute to a growing population of people whose immune systems are weakened by disease or treatment, the opportunistic fungus poses a serious risk.

Last week I had the great good fortune to attend a three day energy conference attended by some of the world’s greatest energy experts.  Thanks to the good graces of the Foundation for the Future I was invited to attend the conference as an observer.  The Foundation invited 15 of the foremost physicists and energy experts in the world to come together for three days of presentations and discussions on the future of energy.  An additional 15 or so people were invited to attend as observers. 

Through photosynthesis, green plants and cyanobacteria are able to transfer sunlight energy to molecular reaction centers for conversion into chemical energy with nearly 100-percent efficiency. Speed is the key - the transfer of the solar energy takes place almost instantaneously so little energy is wasted as heat. How photosynthesis achieves this near instantaneous energy transfer is a long-standing mystery that may have finally been solved.

Researchers from Harvard Medical School and Beth Israel Deaconess Medical Center have captured and sequenced tiny pieces of collagen protein from a 68 million-year-old Tyrannosaurus rex. The protein fragments—seven in all—appear to most closely match amino acid sequences found in collagen of present day chickens.

Are birds and dinosaurs are evolutionarily related?

Groundbreaking international legal principles on sexual orientation, gender identity, and international law have been released by 29 international human rights experts, led by University of Nottingham academic, Professor Michael O'Flaherty.

The "Yogyakarta Principles" call for worldwide action against violence, discrimination and abuse, by governments, the UN human rights system, national human rights institutions, non-governmental organisations, and others.

A new technology developed at the University of Toronto is revealing biochemical processes responsible for diseases such as cystic fibrosis and could one day pave the way for pharmaceutical applications.
