Homeless people are more likely to die early
Homeless people staying in hostels are four times more likely to die early than people in the general population, claim researchers in this week's BMJ. The study involved over 750 people staying in two hostels for the homeless in Copenhagen in 1991. Some were interviewed about several aspects of their lives including upbringing, family background,... view more... (2003-07-09)
Scientists Say Tropics Are Next Emerging Disease Hotspot
Scientists from four well-known institutions say the next major disease like HIV/AIDS or SARS could occur in any of a number of developing countries concentrated along the equator. They encourage increased surveillance to prevent the spread of a potential outbreak. view more (2008-03-14)

Argonne scientists reveal interaction between supersonic fuel spray and its shock wave
Shock waves are a well tested phenomenon on a large scale, but scientists at the U.S. Department of Energy's (DOE) Argonne National Laboratory and their collaborators from Wayne State University and Cornell University have made a breakthrough that reveals the interaction between shockwaves created by high-pressure supersonic fuel jets. view more (2009-03-13)
Compost can turn agricultural soils into a carbon sink, thus protecting against climate change
Applying organic fertilizers, such as those resulting from composting, to agricultural land could increase the amount of carbon stored in these soils and contribute significantly to the reduction of greenhouse gas emissions. view more (2008-02-25)

New INNOGEN Centre Will Help Shape Future Science And Technology Policy
Experts in science, technology, economics and law will explore the impacts of genomics on society, and of society on genomics and related industry sectors, at a new centre set up at the University of Edinburgh. The centre, INNOGEN, funded by a major award of £2m, will act as a 'melting pot' for knowledge and information, as specialists... view more... (2002-11-13)
Symbiotic fungi promote invasion into diverse plant communities (Rudgers et al.)
The biodiversity of a community can affect its functional properties, such as its productiveness or its ability to resist invasion by exotic species. Many grass species host fungi in their leaves that can render them more resistant to herbivory, drought, and competition. In a forthcoming issue of Ecology Letters, Rudgers, Koslow and Clay... view more... (2003-12-10)

Strengthening the tumor-fighting ability of T cells
When faced with cancer, the immune system dispatches cells, called T cells, to kill the tumor. But these killer cells often fail to completely eliminate the tumor because they're deactivated by a distinct population of T cells known as regulatory T cells. view more (2008-03-25)
Genetic study shows humans have pushed orangutans to the brink of extinction

Landmark study details demographic, ecological and genetic spread of rabies in raccoon outbreak
Analyzing 30 years of data detailing a large rabies virus outbreak among North American raccoons, researchers at Emory University have revealed how initial demographic, ecological and genetic processes simultaneously shaped the virus's geographic spread over time. view more (2007-05-18)
What are the benefits and harms of hormone replacement therapy (HRT)?
Women free of menopausal symptoms should not use HRT, but it can help with relief of symptoms, according to a study in this week's BMJ. Researchers at Leicester University carried out a clinical decision analysis on the benefits and harms of HRT, based on the best currently available evidence.

Increased Prevalence Of Diabetes - Not All Bad News (pp 503, 537)
Research published in this week's issue of THE LANCET illustrates how a steady increase in the prevalence of diabetes in a Danish population has not been accompanied by an increase in incidence (new cases) of the disease, as deaths from diabetes have actually fallen over the past decade. The prevalence of diabetes has increased worldwide. Henrik... view more... (2003-08-13)

Primary angioplasty (with stent implantation) is the most effective therapy for acute myocardial infarction (AMI), but it is not available to many patients, even though most European countries have sufficient resources (ie, catheterisation laboratories) for its wider use. view more (2009-09-01)
Finding the constant in bacterial communication
The Rosetta Stone of bacterial communication may have been found. Although they have no sensory organs, bacteria can get a good idea about what's going on in their neighborhood and communicate with each other, mainly by secreting and taking in chemicals from their surrounding environment. view more (2009-07-07)
