Obesity genes probably didn't evolve to help us survive famine
Genes that helped our ancestors store fat in times of famine may have been useful, but whether they cursed future generations with a predisposition toward obesity is a little more controversial. This...
View ArticleHereditary diseases are the price of protection against infections
Almost half our genes can be the starting point for diseases. Scientists have identified 11,000 genes that occur in the human genome in variants that can cause disease. Scientists from the Max Planck...
View ArticleThe herring genome provides new insight on how species adapt to their...
How species genetically adapt to their environment is a central question related to the evolution of biodiversity. In a new study scientists at Uppsala University and their colleagues report that whole...
View ArticleSpelling mutations and evolutionary advantages
DNA codes carrying instructions for creating a protein can sometimes be 'spelt' differently, although they specify the exact same sequence information to create that protein. Scientists from the...
View ArticleModified mosquitoes could help fight against malaria
For the first time, malarial mosquitoes have been modified to be infertile and pass on the trait rapidly - raising the possibility of reducing the spread of disease.
View ArticleBreeding higher yielding crops by increasing sugar import into seeds
Once a mother plant releases its embryos to the outside world, they have to survive on their own without family protection. To ensure successful colonization by these vulnerable creatures, the mother...
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.
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 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 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 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 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 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 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 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 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 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 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 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 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...
