Important sporting events can trigger heart attacks in men
Men are more likely to suffer a heart attack or stroke on the day of important sporting events, probably because of increased stress, claim researchers from The Netherlands in this week's Christmas issue of the BMJ.

Scientists suspect new genetic risk factor for late onset Alzheimer's disease
Three new, separate research studies suggest that a gene or genes on chromosome 10 may be risk factors for late onset Alzheimer's disease (AD).

New genetic link for late onset Alzheimer's disease discovered
Mass. General researchers have found a region on human chromosome 10 that could harbor a genetic variant that powerfully predisposes people to develop late onset Alzheimer's disease.

7,000 feet under the Sea: LSU scientists take geology to great depths
Recently, two LSU geology professors took their research to new depths - 7,000 feet down into the Gulf of Mexico, to be exact -- to study hydrocarbon seeps, gas hydrates and the single-celled micro-organisms called foraminifera that live in those environments.

MIT radar technology to treat breast cancer
An MIT researcher's work on radar technology to detect missiles will be applied in FDA-approved Phase II clinical trials for the treatment of breast cancer.

Debilitating lupus disease may have simple cause, new UCSF research shows
Scientists have discovered that a single defect in a common protein causes a severe auto-immune disease resembling lupus - the debilitating, poorly understood malady that affects 100,000 people in the U.S., mostly young women.

Robo Lego: modular robotic units designed to meld together for search and rescue
The science of robotics is starting to catch up with Saturday morning cartoons.

DNA arrays decipher genome's master switches
Researchers at Whitehead Institute and Corning Inc. have invented a powerful new microarray technique that can decipher the function of master switches in a cell by identifying the set of genes they control.

Computer generates comparative gene maps
Cornell University researchers have developed a method for creating comparative gene maps on a computer, reducing a process that sometimes takes months by hand to a few hours.

The spirits of Christmases past have a strong influence on our health today
Using maps of poverty, made over 100 years ago, researchers in this week's Christmas issue of the BMJ, show that there has been little change in the distribution of poverty in inner London between the 19th and 20th centuries.

January Geology and GSA Today media highlights
Includes: palynological evidence for abrupt dinosaur extinction at the K/T boundary; role of ocean chemistry and circulation in the end-Permian mass extinction; new indicator of shock-wave effects from large impact events; mass spectrometry study with significant implications for dating evolution of Asian Homo erectus; evidence that polar ice caps were smaller during Pleistocene interglacial climates; new understanding of active faults underlying the Los Angeles region.

New York women are still out in the (economic) cold
New York women's economic equality and political participation lag behind other states, says a new report,

American Thoracic Society news tips for December
Newsworthy studies from the December American Thoracic Society peer-reviewed journals include: a large study showing that more comprehensive investigation is needed to uncover close contacts of infectious tuberculosis patients; that Canadian researchers have discovered a high rate of occupational asthma; and that asthmatic children show large lung deficits from exposure to maternal smoking in the womb.

Chemists describe "zipper teeth" of DNA molecules -- publish results in the journal 'Nature'
Experimental scientists have just published findings that represent a major step forward in their understanding of the individual molecules that comprise our DNA -- the neatly coded spiral strands of information that hold all of our biological information, including whether we have red hair or black, blue eyes or brown

UCSD and Japanese researchers identify new gene involved in development and function of central nervous system
A new gene directly involved in the migration of neurons to the developing brain, and then in the ongoing function of the mature central nervous system, has been identified and described by researchers from the UCSD School of Medicine and the Shirakawa Institute of Animal Genetics in Japan.

Researchers identify genetic risk for Alzheimer's disease
Investigators at Washington University in St. Louis led an international research team that has identified a new genetic risk factor for Alzheimer's disease.

Wake Forest to conduct nationwide census and survey of adult day centers
The Robert Wood Johnson Foundation has awarded Wake Forest University School of Medicine Department of Psychiatry a $400,000 grant to assess the scope and adequacy of adult day services in the United States. is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to
