pHlight of the mayfly
Ecologists at Cardiff University are using genetic techniques alongside classical ecology to help explain why Welsh streams are not recovering from the biological damage done by acid rain. Speaking at the British Ecological Society’s Winter Meeting, to be held at the University of Warwick on 18–20 December 2001, Ceri Williams will... view more... (2001-12-10)
Johns Hopkins researchers discover new schizophrenia gene
Researchers at the Johns Hopkins University School of Medicine are one gene closer to understanding schizophrenia and related disorders. Reporting in the Jan. 9 issue of the American Journal of Human Genetics, the team describes how a variation in the neuregulin 3 gene influences delusions associated with schizophrenia. view more (2009-02-04)
Impulse control area in brain affected in teens with genetic vulnerability for alcoholism
A new study suggests that genetic factors influence size variations in a certain region of the brain, which could in turn be partly responsible for increased susceptibility to alcohol dependence. view more (2008-11-07)
Large European study finds gene variant is no strong risk factor for osteoporosis
Variations in a number of different genes and environmental factors affect an individual's risk for osteoporosis. view more (2006-02-21)
Global structures of the DE3 tide
Researchers from LAGEO , the Institute of Atmospheric Physics, has shown that the DE3 tide can propagate up to above 110 km height and exhibits 2-year cycle oscillation. Among all the diurnal tides in the upper atmosphere, this tide is the most prominent component other than the migrating diurnal tide. view more (2008-12-30)
Mean Population Size Increases with Diversity
A long-standing debate in ecology has been the effect of diversity on the temporal stability of biological systems. Ecological theory predicts that the stability of populations should decline as community diversity increases, in part, because population size is assumed to decline with community richness. In the February issue of Ecology Letters,... view more... (2003-01-28)
Right warfarin dose determined by 3 genes
Researchers at Uppsala University, together with colleagues at the Karolinska Institute and the Sanger Institute, have now found all the genes the determine the dosage of the blood-thinning drug warfarin. The findings are published in the scientific journal PLoS Genetics. view more (2009-03-20)
Defining DNA differences to track and tackle typhoid
For the first time, next-generation DNA sequencing technologies have been turned on typhoid fever - a disease that kills 600,000 people each year. The results will help to improve diagnosis, tracking of disease spread and could help to design new strategies for vaccination. view more (2008-07-28)
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)
Identification of genetic risk factor for coeliac disease promises improved treatment
An international research consortium investigating the genetic causes of intestinal inflammatory conditions has identified a new genetic risk factor for coeliac disease. view more (2007-06-11)
Ability to listen to 2 things at once is largely inherited, says twin study
Your ability to listen to a phone message in one ear while a friend is talking into your other ear-and comprehend what both are saying-is an important communication skill that's heavily influenced by your genes. view more (2007-07-18)
Some smokers have genetic predisposition to develop COPD, research shows
Some people have a genetic variation that makes them more susceptible to chronic obstructive pulmonary disease (COPD) if they smoke tobacco, according to new research from Wake Forest University School of Medicine and colleagues. view more (2007-07-12)
Constant sunlight linked to summer suicide spike
Suicide rates in Greenland increase during the summer, peaking in June. Researchers writing in the open access journal BMC Psychiatry speculate that insomnia caused by incessant daylight may be to blame. view more (2009-05-08)
Different coat color may not mean different species for lemurs
Researchers have found that lemurs suspected to belong to different species because of their strikingly different coat colors, are not only genetically alike, but belong to the same species. view more (2006-11-16)
Genetic map offers new tool for malaria research
An international research team announced today the completion of a genome-wide map that charts the genetic variability of the human malaria parasite Plasmodium falciparum. view more (2006-12-11)
High risk of breast cancer associated with genetic variation in leptin and its receptor
Individuals with either of two genetic variations that lead to high serum levels of the cytokine leptin and to overexpression of leptin in fatty tissue, are more at risk of developing breast cancer than others. view more (2006-02-21)
History-hunting geneticists can still follow familiar trail
As the world's first explorers branched away from humanity's birthplace in east Africa some 65,000 years ago, distinct mutations accumulated in the DNA of each population, essentially providing a genetic trail for modern researchers to follow. view more (2006-12-20)
Greatest thing since sliced bread: New data offer important clues toward improving wheat yields
Breed a better crop of wheat? That's exactly what a team of researchers from Kansas State University and the U.S. Department of Agriculture hope their research will lead to. view more (2009-03-11)
Researchers uncover new piece to the puzzle of human height
In studies involving more than 35,000 people and a survey across the entire human genome, an international team supported in part by the National Institutes of Health (NIH) has found evidence that common genetic variants recently linked to osteoarthritis may also play a minor role in human height. view more (2008-01-14)
Study a step toward disease-resistant crops, sustainability
A five-year study that could help increase disease resistance, stress tolerance and plant yields is under way at Purdue University. view more (2008-11-13)
