New methods offer insight into regulatory DNA
Through the Human Genome Project, the HapMap Project and other efforts, we are beginning to identify genes that are modified in some diseases. More difficult to measure and identify are the regulatory regions in DNA - the 'managers' of genes - that control gene activity and might be important in causing disease. view more (2005-12-16)
1 moose, 2 moose: Scientist seeks correction in number of species
It is a misinterpretation of the application of the bedrock of scientific naming with regard to the number of moose species that Kris Hundertmark, a University of Alaska Fairbanks wildlife geneticist at the Institute of Arctic Biology, seeks to correct. view more (2009-06-15)
DNA template could explain evolutionary shifts
Rearrangements of all sizes in genomes, genes and exons can result from a glitch in DNA copying that occurs when the process stalls at a critical point and then shifts to a different genetic template, duplicating and even triplicating genes or just shuffling or deleting part of the code within them, said researchers from Baylor College of Medicine... view more...

New method of selecting DNA for resequencing accelerates discovery of subtle DNA variations
A new technology developed by scientists at Emory University will allow researchers to more easily discover subtle and overlooked genetic variations that may have serious consequences for health and disease. Called Microarray-based Genomic Selection (MGS), the research protocol allows scientists to extract and enrich specific large-sized DNA... view more... (2007-10-15)
Genetic differences influence aging rates in the wild
Long-lived, wild animals harbor genetic differences that influence how quickly they begin to show their age, according to the results of a long-term study reported online on December 13th in Current Biology, a Cell Press publication. view more (2007-12-13)
Study rules out ancient 'bursts' of methane from seafloor deposits
A dramatic increase about 12,000 years ago in levels of atmospheric methane, a potent greenhouse gas, was most likely caused by higher emissions from tropical wetlands or from plant production, rather than a release from seafloor methane deposits. view more (2006-08-25)
Why do insects like to eat some plants more than others?
In a study appearing in the forthcoming issue of The American Naturalist, Tom E. X. Miller, Andrew J. Tyre, and Svata M. Louda (all of the University of Nebraska, Lincoln) examined herbivore dynamics, specifically why plants aren't all eaten at the same rate. view more (2006-11-14)
Gene variation is 'major genetic determinant of psoriasis'
A specific genetic region that has been increasingly identified as the strongest genetic link to psoriasis has an even more significant role in the chronic skin disease than has been suspected, University of Utah medical researchers show in a new study. view more (2009-08-28)
On the volcano island Krakatau: regeneration of rain forest goes hand in hand with genetic diversity
Rain-forest trees colonizing a new piece of land contain a large genetic diversity. The Indonesian island Krakatau is a good natural test case for disrupted tropical rain forest. Here, fig species hybridise unexpectedly. A lesson for the future of nature reserves. Just today, May 13, Tracey Parrish of the Netherlands Institute of Ecology... view more... (2002-05-13)
Scientists Identify Bovine Gene Regulating Milk Production
MTT Agrifood Research Finland and the University of Lie'ge, Belgium, have worked together successfully in locating a gene that regulates total yield and protein and fat content of milk. The scientists found a variation in the growth hormone receptor gene in the bovine chromosome 20. The variation in the receptor gene is associated with a major... view more... (2003-02-20)
Genetic variation linked to age-related macular degeneration
The combination of a certain genetic variation, along with inflammatory factors and smoking, significantly increases the risk of the vision disorder age-related macular degeneration view more (2006-07-19)
Genetic variation associated with poorer response, cardiovascular outcomes with use of clopidogrel
Patients with a certain genetic variation who received the antiplatelet drug clopidogrel had a decreased platelet response to treatment and among those who had percutaneous coronary intervention (procedures such as balloon angioplasty or stent placement used to open narrowed coronary arteries) had an increased risk of having a cardiovascular event... view more...

Heavier hydrogen on the atomic scale reduces friction
Scientists may be one step closer to understanding the atomic forces that cause friction, thanks to a recently published study by researchers from the University of Pennsylvania, the University of Houston and the U.S. Department of Energy's Argonne National Laboratory. view more (2007-11-05)
'Ultra-primitive' particles found in comet dust
Dust samples collected by high-flying aircraft in the upper atmosphere have yielded an unexpectedly rich trove of relicts from the ancient cosmos, report scientists from the Carnegie Institution. view more (2009-11-03)
Prehistoric mystery organism verified as giant fungus
Scientists at the University of Chicago and the National Museum of Natural History in Washington, D.C., have produced new evidence to finally resolve the mysterious identity of what they regard as one of the weirdest organisms that ever lived. view more (2007-04-23)
Genes and environment important in families with history of high cholesterol
Risk of death varies significantly among patients with a family history of high cholesterol (familial hypercholesterolaemia), with many untreated patients reaching a normal life span, finds a study in this week's BMJ. This suggests that strong interactions between genetic and environmental factors are involved in this disorder, and emphasises how... view more... (2001-04-24)
Experts predict high mortality rates from pulmonary fibrosis will continue to rise
Mortality rates from pulmonary fibrosis (PF) have increased significantly in recent years, and are predicted to continue to rise, according to researchers from the University of Colorado. view more (2007-08-01)
Researchers announce results of study on genetic variation in Parkinson's disease
Researchers at the National Institutes of Health (NIH) have completed one of the first large-scale studies of the role of common genetic variation in Parkinson's disease (PD). view more (2006-09-28)
Largest study of its kind implicates gene abnormalities in bipolar disorder
