Study finds connections between genetics, brain activity and preference
A team of researchers from Massachusetts General Hospital (MGH) has used brain imaging, genetics and experimental psychology techniques to identify a connection between brain reward circuitry, a behavioral measurement of preference and a gene variant that appears to influence both. view more (2008-08-07)
Breast cancer risk varies significantly among BRCA1 and BRCA2 carriers
There is a broad variation in the risk of developing breast cancer among people who carry the BRCA1 and BRCA2 gene mutation, according to a study in the January 9/16 issue of JAMA. view more (2008-01-09)
Arctic Sediments Show That 20th Century Warming Is Unlike Natural Variation
The possibility that climate change might simply be a natural variation like others that have occurred throughout geologic time is dimming, according to evidence in a Proceedings of the National Academy of Sciences paper published today. view more (2009-10-26)
New biomarkers could help doctors spot Alzheimer's and other neurodegenerative diseases
Neurodegenerative diseases like Alzheimer's and Parkinson's in their early stages can be difficult for physicians to spot, and many diagnoses are incorrect. view more (2006-08-14)
Bug-Zapper: A dose of radiation may help knock out malaria
How are physicists helping an effort to eradicate malaria, the mosquito-borne disease that kills more than one million people every year" Researchers at the National Institute of Standards and Technology (NIST) used their expertise in radiation science to help a young company create weakened, harmless versions of the malaria-causing parasite. view more (2007-11-09)
Accuracy of past hurricane counts good
Counting tropical storms that occurred before the advent of aircraft and satellites relies on ships logs and hurricane landfalls, making many believe that the numbers of historic tropical storms in the Atlantic are seriously undercounted. view more (2007-11-26)
LGC licenses Orchid to test for drug metabolising gene
LGC, the UK`s leading independent provider of genetic testing services, has issued its first testing licence for the key DNA variant in the drug metabolising gene CYP2D6 to Orchid BioSciences Inc.

University study shows low radiological risk to the public around atomic sites
A study team led by experts at the University of Southampton has found that there is no significant risk to the public from radioactive contamination from the Atomic Weapons Establishments at Aldermaston and Burghfield in West Berkshire. The three-year environmental radioactivity project, carried out by the University's Geosciences Advisory Unit... view more... (2002-08-07)
Researchers establish common seasonal pattern among bacterial communities in Arctic rivers
New research on bacterial communities throughout six large Arctic river ecosystems reveals predictable temporal patterns, suggesting that scientists could use these communities as markers for monitoring climate change in the polar regions. view more (2009-11-24)
Ethnicity affects timing and access to cardiac care
Ethnicity is having a significant impact on timely access to cardiac care in Calgary and likely across Canada as the population's ethnic diversity grows, according to new research led by a team from the University of Calgary. view more (2009-05-06)

2 oxygenation events in ancient oceans sparked spread of complex life
The rise of oxygen and the oxidation of deep oceans between 635 and 551 million years ago may have had an impact on the increase and spread of the earliest complex life, including animals. view more (2008-02-26)
Genetic analysis helps dissect molecular basis of cardiovascular disease
Using highly precise measurements of plasma lipoprotein concentrations determined by nuclear magnetic resonance spectroscopy (NMR), researchers led by Daniel Chasman at Brigham and Women's Hospital and Harvard Medical School in Boston, MA, the Framingham Heart Study in Framingham, and the PROCARDIS consortium in Stockholm, Sweden and Oxford,... view more...

Arctic spring comes weeks earlier than a decade ago
In the Earth's cold and icy far north, the harsh winters are giving way to spring weeks earlier than they did just a decade ago, researchers have reported in the June 19th issue of Current Biology, published by Cell Press. view more (2007-06-19)
If your first cigarette gave you a buzz and you now smoke, a gene may be to blame
Anyone who has ever tried smoking probably remembers that first cigarette vividly. For some, it brought a wave of nausea or a nasty coughing fit. For others, those first puffs also came with a rush of pleasure or "buzz." view more (2008-08-11)
Climate models need deeper roots, scientists say
By soaking up moisture with their roots and later releasing it from their leaves, plants play an active role in regulating the climate. In fact, in vegetated ecosystems, plants are the primary channels that connect the soil to the atmosphere, with plant roots controlling the below-ground dynamics. view more (2005-12-06)
