Other Illnesses, Body Weight Do Not Explain Racial Disparities in Colon Cancer Survival, UAB Researchers Say
A new study by University of Alabama at Birmingham (UAB) researchers shows that body-mass index (BMI) and co-existing medical conditions (co-morbidity) do not explain the decreased survival observed among African-Americans compared to Caucasians who also have colon cancer. view more (2009-11-24)
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)
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...

Gene mismatch influences success of bone marrow transplants
A commonly inherited gene deletion can increase the likelihood of immune complications following bone marrow transplantation, an international team of researchers reports in the November 22 advance online issue of Nature Genetics. view more (2009-11-23)
New map of variation in maize genetics holds promise for developing new varieties
A new study of maize has identified thousands of diverse genes in genetically inaccessible portions of the genome. New techniques may allow breeders and researchers to use this genetic variation to identify desirable traits and create new varieties that were not easily possible before. view more (2009-11-20)
New Maize Map to Aid Plant Breeding Efforts
In a massive survey of genetic diversity in maize, also known as corn, researchers across the United States, have developed a gene map that should pave the way to significant improvements in a plant that is a major source of food, fuel, animal feed and fiber around the world. view more (2009-11-20)
New research helps explain why bird flu has not caused a pandemic
Bird flu viruses would have to make at least two simultaneous genetic mutations before they could be transmitted readily from human to human, according to research published today in PLoS ONE. view more (2009-11-19)
Women at risk from vitamin A deficiency
Almost half of UK women could be suffering from a lack of vitamin A due to a previously undiscovered genetic variation, scientists at Newcastle University have found. view more (2009-11-18)
Climate variability impacts the deep sea
Deep-sea ecosystems occupying 60% of the Earth's surface could be vulnerable to the effects of global warming warn scientists writing in the Proceedings of the National Academy of Sciences. view more (2009-11-03)
New tool promises more accurate antimalarial drug dosing
Scientists at LSTM have developed a tool to support the development of appropriate age-based dosing regimens for malaria drugs. view more (2009-10-30)
Genetic links to fungal infection risk identified
Two genetic mutations that may put individuals at increased risk of fungal infections have been identified by scientists from UCL and Radboud University, increasing understanding about the genetic basis of these infections and potentially aiding the development of new treatments. view more (2009-10-29)
Sex-based prenatal brain differences found
Prenatal sex-based biological differences extend to genetic expression in cerebral cortices. The differences in question are probably associated with later divergences in how our brains develop. view more (2009-10-26)
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)
Standards for a new genomic era
A team of geneticists at Los Alamos National Laboratory, together with a consortium of international researchers, has recently proposed a set of standards designed to elucidate the quality of publicly available genetic sequencing information. view more (2009-10-22)
Eutrophication affects diversity of algae
Eutrophication of the seas may have an impact on genetic variation in algae, research at the University of Gothenburg shows. view more (2009-10-20)
Being a standout has its benefits, study shows
Standing out in a crowd is better than blending in, at least if you're a paper wasp in a colony where fights between nest-mates determine social status. view more (2009-10-16)
Blood counts are clues to human disease
A new genome-wide association study published today in Nature Genetics begins to uncover the basis of genetic variations in eight blood measurements and the impact those variants can have on common human diseases. view more (2009-10-12)
Ironing out the genetic cause of hemoglobin problems
A gene with a significant effect on regulating hemoglobin in the body has been identified as part of a genome-wide association study, which looked at the link between genes and hemoglobin level in 16,000 people. view more (2009-10-12)
Jumping genes, gene loss and genome dark matter
In research published today by Nature, an international team describes the finest map of changes to the structure of human genomes and a resource they have developed for researchers worldwide to look at the role of these changes in human disease. view more (2009-10-08)
Genome-wide study of autism published in Nature
In one of the first studies of its kind, an international team of researchers has uncovered a single-letter change in the genetic code that is associated with autism. view more (2009-10-08)
