Altered gene protects some African-Americans from coronary artery disease
A team of scientists at Johns Hopkins and elsewhere has discovered that a single alteration in the genetic code of about a fourth of African-Americans helps protect them from coronary artery disease,...
View ArticleGenes of the immune system are associated with increased risk of mental illness
Genes linked to the immune system can affect healthy people's personality traits as well as the risk of developing mental illness and suicidal behaviour, reveals a thesis from the University of...
View ArticleGenomic tools can help researchers develop crops quickly
(PhysOrg.com) -- Using powerful genome sequencing tools created for human genetics, researchers can now exploit the genetic diversity of crops to improve productivity, sustainability and nutrition, a...
View ArticleResearch identifies wild ancestor genes for crop improvement
Using the genetic variation found in wild and exotic rice species, researchers are providing breeders with genomics tools and knowledge to develop higher yielding, stress-tolerant varieties, a Cornell...
View ArticleGene variants in autism linked to brain development
New research on the genomics of autism confirms that the genetic roots of the disorder are highly complicated, but that common biological themes underlie this complexity. In the current study,...
View ArticleWith secondhand gene, 'freaky mouse' defeats common poison
Over millennia, mice have thrived despite humanity's efforts to keep them at bay. A Rice University scientist argues some mice have found two ways to achieve a single goal -- resistance to common poison.
View ArticleMutants with heterozygote disadvantage can prevent spread of transgenic animals
Genetically modified animals are designed to contain the spread of pathogens. One prerequisite for the release of such organisms into the environment is that the new gene variant does not spread...
View Article'Speed gene' in modern racehorses originated from British mare 300 years ago
Scientists have traced the origin of the 'speed gene' in Thoroughbred racehorses back to a single British mare that lived in the United Kingdom around 300 years ago, according to findings published in...
View ArticleTwo genes do not make a voter: new research
Voting behavior cannot be predicted by one or two genes as previous researchers have claimed, according to Evan Charney, a Duke University professor of public policy and political science.
View ArticleJockeying for genetic advantage
When you buy a racehorse, you pays your money and you takes your chances. Top yearlings at Keeneland's 2011 Thoroughbred auction, for instance, averaged nearly $350,000 and hadn't yet raced a step....
View ArticleResearchers crack olfactory code for partner selection, synthesise first...
(Medical Xpress)—Individual body odour plays an important role in partner selection. Humans, mice, fish and birds, and probably other vertebrates too, receive important information about a potential...
View ArticleWild mice have natural protection against Lyme borreliosis
Like humans, mice can become infected with Borrelia. However, not all mice that come into contact with these bacteria contract the dreaded Lyme disease: Animals with a particular gene variant are...
View ArticleNew DNA cattle test beefs up dairy and meat quality
(Phys.org) —A genomics technique developed at Cornell to improve corn can now be used to improve the quality of milk and meat, according to research published online May 17 in the journal PLOS ONE.
View ArticleMycobacteria get all the advantages of sex with none of the downsides
Sexual reproduction is costly to those organisms that depend on it, like humans. For starters, only half of the population can bear offspring and the other half has to work hard to make sure they're...
View ArticleIrish potato famine-causing pathogen even more virulent now
(Phys.org) —The plant pathogen that caused the Irish potato famine in the 1840s lives on today with a different genetic blueprint and an even larger arsenal of weaponry to harm and kill plants.
View ArticleGene determines acceptance, rejection of stem cells from others of the same...
(Phys.org) —To live together harmoniously in our bodies, cells need to be able to distinguish which of those among them are sanctioned residents and which are interlopers. This way, native cells can be...
View ArticleUsing genes to rescue animal and plants from extinction
(Phys.org) —With estimates of losing 15 to 40 percent of the world's species over the next four decades – due to climate change and habitat loss, researchers ponder in the Sept. 26 issue of Nature...
View ArticleGenetic data can help predict how pine forests will cope with climate change
Data from only a small number of gene variants can predict which maritime pine trees are most vulnerable to climate change, scientists report in the March issue of Genetics. The results will improve...
View ArticleThe winner doesn't always take all
Theoretically predicted and now demonstrated experimentally for the first time using soil bacteria: weaker organisms can prevail against stronger ones—if they are superior in number. This acts as a...
View ArticleScientists pinpoint gene for better rice
Scientists said Monday they had pinpointed variants of a gene to improve the quality and yield of rice, a staple starch for billions of people.
