Boston, MA -- Barry R. Bloom, Dean of the Harvard School of Public Health, today expressed "deep concern regarding the detention by Iranian authorities of Dr. Kamiar Alaei, a 2007 Masters of Science graduate of our School, and of his brother, Dr. Arash Alaei. The brothers are Iranian physicians working on the prevention and treatment of HIV/AIDS, an important public health problem in their country."

Many sports teams select their uniforms based on the mascot, city or country they are representing, not on a referee's preference or bias. But a new study has found that choosing the color red for a uniform in competitive sports can actually affect the referee's split-second decision-making ability and even promote a scoring bias.

Eating oily fish once a week may reduce age-related macular degeneration(AMD) which is the major cause of blindness and poor vision in adults inwestern countries and the third cause of global blindness, according toa study published today in the American Journal of Clinical Nutrition.

More than 20 grass-roots standardisation groups, led by scientists at the European Bioinformatics Institute (EMBL-EBI) and the Centre for Ecology & Hydrology (CEH), have combined forces to form the "Minimum Information about a Biomedical or Biological Investigation" (MIBBI) initiative (www.mibbi.org). Their aim is to harmonise standards for high-throughput biology, and their methodology is described in a Commentary article, published today in the journal Nature Biotechnology.

Australian scientists have identified a way to 'switch off' a molecule, a key player in the molecular processes that trigger breast cancer and certain forms of leukaemia.

The molecule, known as Gab2, operates downstream of a major breast cancer oncogene, HER2, the target of the drug Herceptin.

A research team from the Garvan Institute of Medical Research, led by Professor Roger Daly, has found a novel way of blocking signals to and from Gab2, preventing it from fulfilling its role in cell proliferation. The finding is published online today in the EMBO Journal.

As we come close to the Beijing Olympic Games, a review article, http://www.cmaj.ca/cgi/rapidpdf/cmaj.080982, in CMAJ (Canadian Medical Association Journal) reminds us that the heat and humidity in the Beijing region will present a formidable challenge to all athletes. Moreover, poor quality of air can also affect all athletes, especially those with asthma.

Long a problem in the western U.S., the New Zealand mud snail currently inhabits four of the five Great Lakes and is spreading into rivers and tributaries, according to a Penn State team of researchers. These tiny creatures out-compete native snails and insects, but are not good fish food replacements for the native species.

There are few things more irritating than a fly buzzing around the house. South Africans have an unconventional solution to the problem. They hang up a bunch of Roridula gorgonias leaves. Attracted to the shiny adhesive droplets on the leaf's hairs, the hapless pest is soon trapped by the natural flypaper. However, this is not the end of the story. Each R. gorgonias plant is home to a population of Pameridea roridulae (mirid bugs), which dine on the trapped insects. Yet the mirid bugs successfully evade their host's sticky clutches.

High levels of testosterone may be a key factor in spreading disease among mice, according to biologists. The findings could help explain why males in a population are often more likely to get infected, and transmit disease.

Previous research has linked testosterone, the male sex hormone, to immune system suppression. Studies have shown that males, compared to females, experience more bouts of disease, and account for a larger share of disease transmission. However, it is not fully clear what makes males such super-spreaders of disease.

In the last 60 years, brown tree snakes have become the embodiment of the bad things that can happen when invasive species are introduced in places where they have few predators. Unchecked for many years, the snakes caused the extinction of nearly every native bird species on the Pacific island of Guam.

A variety of other damage has been directly attributed to brown tree snakes, including large population losses among other native animal species in Guam's forests, attacks on children and pets, and electrical power outages.

The links between HIV transmission and the degree to which people are able to adopt realistic plans to achieve future projects, in other words, hope, have been overlooked in policies to tackle HIV/AIDS. New research funded by the Economic and Social Research Council (ESRC) argues that hope is a powerful tool in the battle to stop the spread of HIV/AIDS.

DURHAM, N.C. -- Testing men for elevated levels of prostate-specific antigen (PSA) in the blood -- the gold standard screening test for prostate cancer -- may be biased against obese men, whose PSA levels tend to be deceptively low. And this bias may be creating more aggressive cancers in this population by delaying diagnosis, according to a new study led by investigators in the Duke Prostate Center and the Durham Veterans Affairs (VA) Medical Center.

Long established medical interventions to help couples with infertility problems do not seem to improve fertility, according to a study published on bmj.com today.

These findings challenge current practice in the UK and national guidelines should be reviewed in the light of this evidence, say the authors.

August 8, 2008 – Cone-rod dystrophies (CRDs) are a group of eye diseases caused by progressive loss of the photoreceptor cells in the retina. In a study published online in Genome Research (www.genome.org), researchers have identified a novel mutation in a gene associated with CRD in dogs, raising hopes that potential therapies can be developed for people suffering from these eye disorders.

DERMATOLOGY: Possible new treatment for psoriasis

New data, generated by Thomas Jung and colleagues, at Novartis Exploratory Development, Switzerland, have indicated that a drug known currently as AEB071 can reduce the clinical symptoms of psoriasis, a chronic, currently incurable autoimmune skin disease.
