Recommended activity levels not achieved by obese children and those with liver disease
(University of Surrey) In a new study published today in the journal Nutrients, research from the University of Surrey and the Children's Liver Disease Foundation has found that both obese children and those with non-alcoholic fatty liver disease are not meeting the UK recommendations for a variety of vitamins and minerals.

How a genetic locus protects adult blood-forming stem cells
(Stowers Institute for Medical Research) A particular location in DNA, called the Dlk1-Gtl2 locus, plays a critical role in protecting hematopoietic, or blood-forming, stem cells -- a discovery revealing a critical role of metabolic control in adult stem cells, and providing insight for potentially diagnosing and treating cancer, according to researchers from the Stowers Institute for Medical Research.

Shedding light on oil behaviors before the next spill
(New Jersey Institute of Technology) A comprehensive scientific report released today by The Royal Society of Canada has concluded that there are still critical research gaps hampering efforts to both assess the environmental impacts of crude oil spills and to effectively remediate them.

New gene map reveals cancer's Achilles heel
(University of Toronto) Scientists have mapped out the genes that keep our cells alive, creating a long-awaited foothold for understanding how our genome works and which genes are crucial in disease like cancer.

Closing the loop on an HIV escape mechanism
(University of Delaware) A collaborative six-university research team finds that the motion of a specific protein in a human cell regulates whether HIV will infect other cells. The finding may lead to promising new ways to thwart the virus that causes AIDS.

Researchers assess use of drug-susceptible parasites to fight drug resistance
(University of Georgia) Researchers at the University of Georgia have developed a model for evaluating a potential new strategy in the fight against drug-resistant diseases. The strategy would take advantage of parasite refugia--host populations not treated with drugs, thereby serving as 'safe zones' where parasites don't develop drug resistance. When parasites from refugia mix with their drug-resistant counterparts in the general population, they could reduce the incidence of drug-resistance overall, which may help prolong a drug's effectiveness.

Five MU faculty members named as Fellows of the AAAS
(University of Missouri-Columbia) Five faculty members from the University of Missouri have been named Fellows of the American Association for the Advancement of Science. They join 347 other distinguished scientists who have been awarded this honor by AAAS this year because of their scientifically or socially distinguished efforts to advance science or its applications. The MU faculty members elected as fellows are: David Pintel, Randall Prather, Michael Roberts, Dong Xu and Yuwen Zhang.

Data scientists create world's first therapeutic venom database
(Columbia University Medical Center) What doesn't kill you could cure you. A growing interest in the therapeutic value of animal venom has led a pair of Columbia University data scientists to create the first catalog of known animal toxins and their physiological effects on humans.

Peering into cell structures where neurodiseases emerge
(University of Delaware) In the Proceedings of the National Academy of Sciences, a Univeristy of Delaware-led research team reveals for the first time -- atom by atom -- the structure of CAP-Gly, a protein that binds to the latticework of microtubules in your cells. When mutations occur in CAP-Gly, neurological diseases and disorders occur, including Perry syndrome and distal spinal bulbar muscular dystrophy.

A changing season means a changing diet for bison
(University of Colorado at Boulder) North American bison adjust their diet seasonally in order to take full advantage of the growing season when grasses become less nutritious, a new study led by researchers at the University of Colorado Boulder has discovered.
