Genetic hint for ridding the body of hepatitis C
More than seventy percent of people who contract Hepatitis C will live with the virus that causes it for the rest of their lives and some will develop serious liver disease including cancer. view more (2009-09-17)
Study reveals specific gene in adolescent men with delinquent peers
Birds of a feather flock together, according to the old adage, and adolescent males who possess a certain type of variation in a specific gene are more likely to flock to delinquent peers. view more (2008-10-02)
Patagonian glacier yields clues for improved understanding of global climate change
A better understanding of climate variations at planetary scale is one of climate scientists' crucial concerns. Stable water isotope analysis, the chemistry of ice cores taken from the Arctic and Antarctic polar ice caps and of air bubbles trapped in them now allow a chronology to be drawn up of the climate changes that took place over the past... view more...

National Physical Laboratory Stages Unique On-Line Experiments
Does your computer’s clock always run slow? How good are human beings at estimating? How much does gravity vary over the globe? With your help we are attempting to find answers to these questions as part of a huge on-line Web event to celebrate World Metrology Day 2001, Sunday 20th May. This is the first time NPL have attempted such a... view more... (2001-05-18)
Gene variations linked to brain aneurysms
Variations in a gene seem to be linked to brain (cerebral) aneurysms, suggests research published ahead of print in the Journal of Neurology Neurosurgery and Psychiatry. view more (2006-04-27)
Women's biological clock revealed: Hormone may predict age at menopause
Age at menopause may now be predicted more realistically according to a new study accepted for publication in the Journal of Clinical Endocrinology & Metabolism (JCEM). view more (2008-04-29)
Genes may make some people more prone to anxiety
Inborn differences may help explain why trauma gives some people bad memories and others the nightmare of post-traumatic stress. Scientists in Germany and the United States have reported evidence linking genes to anxious behavior. The findings appear in the August issue of Behavioral Neuroscience, published by the American Psychological... view more... (2008-08-11)
Fossils older than dinosaurs reveal pattern of early animal evolution on Earth
The abundant diversity of characteristics within species likely helped fuel the proliferation and evolution of an odd-looking creature that emerged from an unprecedented explosion of life on Earth more than 500 million years ago. view more (2007-07-27)
UCLA scientists strengthen case for life more than 3.8 billion years ago
Ten years ago, an international team of scientists reported evidence, in a controversial cover story in the journal Nature, that life on Earth began more than 3.8 billion years ago-400 million years earlier than previously thought. view more (2006-07-24)
Emory scientists develop new map of genetic variation in human genome
Emory University scientists have identified and created a map of more than 400,000 insertions and deletions (INDELs) in the human genome that signal a little-explored type of genetic difference among individuals. view more (2006-08-11)
Inherited risk factors increase odds of developing childhood acute lymphoblastic leukemia
Scientists at St. Jude Children's Research Hospital have identified inherited variations in two genes that account for 37 percent of childhood acute lymphoblastic leukemia (ALL), including a gene that may help predict drug response. view more (2009-08-17)
Domestication of Capsicum annuum chile pepper provides insights into crop origin and evolution
Without the process of domestication, humans would still be hunters and gatherers, and modern civilization would look very different. view more (2009-06-22)
Ice Ages and rivers may have affected gorilla diversification
Geography and historical climate change may have both played a major role in gorilla evolutionary diversification, according to a new genetic study by Cardiff University and the University of New Orleans. view more (2007-12-11)
Increasing the success of liver transplants by managing levels of anti-rejection drugs
Approximately 600 children receive liver transplants each year in the United States. The use of immunosuppressant drug therapy, namely calcineurin inhibitors (CNIs) such as cyclosporine and tacrolimus, has decreased the risk of liver rejection and increased patient survival rates. view more (2005-06-13)
A warming climate can support glacial ice
New research challenges the generally accepted belief that substantial ice sheets could not have existed on Earth during past super-warm climate events. view more (2008-01-11)
Genetic Variation Associated With Survival Advantage in African Americans With HIV
From the start of the HIV epidemic, it appeared that some of the people who were infected with the virus were able to ward off the fatal effects of the disease longer than others. view more (2009-07-21)
Where there's muck there's grass
The oldest ecological experiment in the world, set up almost 150 years ago to see whether inorganic fertilisers could produce more grass than traditional animal manures, is becoming an important source of evidence on the impact of climate change on genetic variation in plants. Speaking at the British Ecological Society's Annual Meeting, being... view more... (2003-09-01)
Researchers find new gene linked to breast cancer
Researchers in a multicenter international study have identified a new gene that, if mutated, may increase a woman's risk of breast cancer by more than a third. view more (2007-10-08)
Identified main genetic variants involved in response to HIV
This international collaboration has been the largest ever to have taken place in a large scale study on genetic differences between patients infected by HIV, and is the first study of this kind in the field of infectious disease. view more (2007-07-23)
Cataloging the Structural Variations in Human Genetics
A major new effort to uncover the medium- and large-scale genetic differences between humans may soon reveal DNA sequences that contribute to a wide range of diseases. view more (2007-05-10)
