New study rebuts claims about Icelandic genetic heterogeneity
There has been some controversy in the media and within the scientific research community concerning whether Icelanders are genetically homogenous or heterogeneous relative to other European populations. Following an article published in Annals of Human Genetics in January 2003 by E. 'rnason, who concluded that Icelanders were one of the most... view more... (2003-08-19)
Why didn't Darwin discover Mendel's laws?
Mendel solved the logic of inheritance in his monastery garden with no more technology than Darwin had in his garden at Down House. view more (2009-02-27)
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...

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)
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)

Bats add their voice to the FOXP2 story
When it comes to the FOXP2 gene, humans have had most to shout about. Discoveries that mutations in this gene lead to speech defects and that the gene underwent changes around the time language evolved both implicate FOXP2 in the evolution of human language. view more (2007-09-19)
Canadian breast cancer guidelines do not meet their objective
The Canadian Practice Guidelines for the Care and Treatment of Breast Cancer, first published in 1998, were developed to reduce variation in the way that breast cancer was being treated. view more (2007-03-13)
Study helps preserve arctic whale, Eskimo subsistence hunt
Research on one of the oldest-living mammals - the bowhead whale - has helped preserve a primary food source for Eskimos in the far reaches of Alaska, and also may provide a useful tool for studying genetic variation in other migratory animals. view more (2007-06-13)
Reverse evolution in real-time
In his book, Wonderful World, Stephen Jay Gould writes about an experiment of 'replaying life's tape', wherein one could go back in time, let the tape of life play again and see if 'the repetition looks at all like the original'. view more (2009-01-12)
Genes may determine success of hip replacement surgery
The success of long term hip replacement surgery may lie in the genes, suggests research published ahead of print in the Annals of the Rheumatic Diseases. view more (2007-03-15)
Barnacles go to great lengths to mate
Compelled to mate, yet firmly attached to the rock, barnacles have evolved the longest penis of any animal for their size - up to 8 times their body length - so they can find and fertilize distant neighbours. view more (2008-02-07)
Variation in prostate stem cell antigen gene raises bladder cancer risk
Researchers have pinpointed a specific gene variation that causes increased risk of urinary bladder cancer, according to a scientific team led by The University of Texas M. D. Anderson Cancer Center. view more (2009-08-03)
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)
Research at Durham University finds elephant seal travelling over 8,000 km to mate
Researchers at the University of Durham have identified a male southern elephant seal who was born in the South Pacific and travelled over 8,000 km to mate and reproduce on the Falkland Islands. This is the first demonstration of long-range movement of genes in this species. The research paper is published in the prestigious journal of the... view more... (2003-01-31)
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)
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.

Cutting-edge weapons result of prehistoric experimentation
In today's fast-paced, technologically advanced world, people often take the innovation of new technology for granted without giving much thought to the trial-and-error experimentation that makes technology useful in everyday life. When the "cutting-edge" technology of the bow and arrow was introduced to the world, it changed the way... view more... (2008-06-11)
