Cases of deep vein thrombosis and pulmonary embolism peak in winter
Admissions to hospital for deep vein thrombosis and pulmonary embolism are higher in winter and lower in summer, finds a study in this week's BMJ.

Brain imaging study sheds light on moral decision-making
While people regularly reach the same conclusions when faced with uncomfortable moral choices, their answers often do not grow out of the reasoned application of general moral principles.

A new paradigm for anti-angiogenesis therapy
The aim of anti-angiogenesis therapy is to target the abnormal blood vessels growing into a tumor and cut off the blood supply to a cancerous mass.

Pelvic floor exercises can reduce incontinence in women
Three months after childbirth, a third of women still experience urinary incontinence, yet simple treatments such as pelvic floor exercises or bladder training are effective in about one in 10 women, concludes a study in this week's BMJ.

Warming before surgery reduces postoperative wound infection
A randomised trial in this week's issue of THE LANCET shows how postoperative wound infection could be substantially reduced if patients are given localised or systemic warming before undergoing surgery.

Increased depression risk among US women linked to childhood abuse
Increasing prevalence of childhood violence in girls and young women in the USA could explain why women are more likely to be depressed than men in adulthood, suggest authors of a population-based study in this week's issue of THE LANCET.

World's first MRI/x-ray imaging suite installed at UCSF Medical Center in partnership with Philips Medical Systems
The first imaging suite to combine MRI (magnetic resonance imaging) with a cath lab officially opened today at UCSF Medical Center.

Genomes on 'chips' boon to cancer research
New research published in Genome Biology uses microchips coated with DNA to discover the surprising way that the drug flavopiridol acts to kill cancer cells.

Research finding could lead to vaccines effective against a range of cancers, UC Berkeley researchers report
UC Berkeley immunologists have found proteins that only cancer cells, not normal cells, display, and which activate natural killer cells and macrophages - two critical elements of the body's immune system.

Research: U.S. boys also reaching puberty earlier than in past years
U.S. boys appear to reach puberty earlier than in past decades, a new study suggests, but why that happens is not clear and neither are the health consequences.

Cancer-preventing gene protects against stress and extends life span in worms
A gene that protects against cancer and environmental stress and promotes longevity has been identified in studies of a nematode worm, according to a report to appear in Science and published September 14 on the Science Express web site.

Concern over poor UK recruitment to chemotherapy trials for women at high risk of breast cancer
The effectiveness of prophylactic chemotherapy for women who are at a high risk of breast cancer may remain unclear unless more UK women are recruited to chemotherapy trials, conclude authors of a research letter in this week's issue of THE LANCET.

Field trials used to investigate the social lives of badgers
New research published in BMC Ecology investigates why badgers, an antisocial species, choose to live in groups.

Black holes take the plunge
For the first time computer simulations by the Max Planck Institute for Gravitational Physics predict what astronomers will

Researchers at UT Southwestern discover how neurons communicate to 'wire' developing brain
Researchers at UT Southwestern Medical Center at Dallas have discovered a biochemical pathway that helps describe how neurons in the brain and spinal cord form their connections.

Studies offer data on potential impact of Reminyl on caregiver 'burden' in Alzheimer's disease
Reminylâ„¢ (galantamine) - the newest medication approved to treat mild to moderate Alzheimer's disease - can ease the burden on family caregivers by reducing the amount of time required for supervision and assistance, as well as by alleviating the stress associated with these responsibilities, suggest data presented today at the Tenth Congress of the International Psychogeriatric Association (IPA).

Gene therapy technique reduces alcohol consumption in rats
Scientists at the U.S. Department of Energy's Brookhaven National Laboratory report in the current Journal of Neurochemistry (Volume 78, Number 5) that they used gene therapy techniques to increase levels of dopamine D2 (DRD2) receptors and reduce drinking in rats previously trained to self-administer alcohol.

Risky anaesthetic machines in use in many UK hospitals
A letter published in this week's BMJ suggests that nearly 30 percent of anaesthetic machines in UK hospitals may not have the anti-hypoxia device which would prevent the accidental delivery of pure nitrous oxide to patients.

URI oceanographers link warmer water temperatures and the decline of winter flounder
Biological oceanographers Aimee Keller and Grace Klein-MacPhee at the University of Rhode Island's Graduate School of Oceanography have conducted experiments on winter flounder that suggest that the decline of the species in Narragansett Bay may be the result of elevated winter water temperatures.

Science study pinpoints active fault tied to central Europe's worst earthquake and predicts seismic pattern
Beneath the suburban neighborhoods and forests immediately south of this cultural mecca, an active fault continues to tremble, some 645 years after it caused the worst earthquake in central European history, the journal Science reports.

UMass team develops new way to fabricate future generations of integrated circuits
A research team led by University of Massachusetts chemical engineer James Watkins has developed a new method of depositing copper films within tiny channels etched in silicon wafers.

DNA transcription is tuned to specific cells
HHMI researchers have found a new example of how the machinery that controls the transcription of DNA to messenger RNA (mRNA) is tailored to specific cells or genes.

Mild hyperthyroidism linked to increased mortality among elderly people
Elderly people with slightly raised thyroid hormone concentrations-but who do not have overt thyroid disease-could be at an increased risk of death from cardiovascular disease, suggest authors of a study in this week's issue of THE LANCET.

Amnesty bins at dance venues may help tackle drug use
A new method designed to monitor drug consumption at dance venues may lead to more effective campaigns against drug use, finds a study in this week's BMJ.

The nanoelectronic road ahead: Despite challenges, silicon offers 20 more years of semiconductor progress
Fundamental limits imposed by the laws of physics threaten to halt continued miniaturization of silicon semiconductors, clouding the future of an information technology boom that has fueled economic growth over the past four decades.
