Liver, Not Brain, May Be Origin of Alzheimer’s Plaques
Unexpected results from a Scripps Research Institute and ModGene, LLC study could completely alter scientists’ ideas about Alzheimer’s disease — pointing to the liver instead of the brain as the source of the “amyloid” that…

Scientists Show How Men Amp Up Their X Chromosome
Vive la différence? Not at the level of DNA. Men must increase gene expression on their lone X-chromosome to match the two X’s possessed by women. A new study explains just how men manage to…

Analysis of Bread Mold Genomes Demonstrates ‘Reverse-Ecology’ Tool
In a demonstration of “reverse-ecology,” biologists at the University of California, Berkeley, have shown that one can determine an organism’s adaptive traits by looking first at its genome and checking for variations across a population.…

Antifreeze Proteins: How One Gene Becomes Two (With Different Functions)
Researchers report that they are the first to show in molecular detail how one gene evolved two competing functions that eventually split up — via gene duplication — to pursue their separate destinies. The study,…

How the insects survive a parasite that causes malaria in humans
By unraveling the mysteries that exist within the molecular composition of mosquitoes, a team of Kansas State University researchers is trying to discover how the insects survive a parasite that causes malaria in humans. Kristin…

A new type of genetic variation could strengthen natural selection
The unexpected discovery of a new type of genetic variation suggests that natural selection – the force that drives evolution – is both more powerful and more complex than scientists have thought. “We have discovered…

Can increase genes of pregnant women the risk of preterm labor?
New evidence that genetics play a significant role in some premature births may help explain why a woman can do everything right and still give birth too soon. Research presented today at the 30th Annual…

Possible pharmacological target(s) identified in pediatric OSA
Children with obstructive sleep apnea (OSA) may one day be able to have an injection or use a throat spray instead of getting their tonsils removed to cure their snoring, according to a new study…

Introducing New Genes for Restoration Purposes May Affect Local Populations
Re-vegetation seems like a beneficial strategy for conserving and restoring damaged ecosystems, and using a variety of species can help increase biodiversity in these systems. But what are the risks involved with introducing seeds from…

Polar Bear Droppings Advance Superbug Debate
Scientists investigating the spread of antibiotic-resistant superbugs have gone the extra mile for their research — all the way to the Arctic. Researchers writing in the open access journal BMC Microbiology found little sign of…
