UCLA researchers report that a recently discovered Alzheimer's gene possessed by most people impairs the development of myelin, the protective covering around the neuron's axons, making it weaker and more vulnerable to the onset of Alzheimer's much later in life.

New findings by a team of Australian and Swedish researchers will go a long way toward explaining the underlying causes of male infertility.
A program to educate students about heart-healthy lifestyles resulted in significant improvements in middle school students' cholesterol levels and resting heart rates, including four years of follow-up. Students continued to experience health benefits, make better food choices and participate in physical activities after the intervention, suggesting that such a program could decrease cardiovascular disease and diabetes risks.
Higher hospitalization rates for discretionary conditions may lead to higher readmission rates, a new study found.
Politicians should be careful when they rail against mainstream news media. A study from North Carolina State University shows that perceived bias of media outlets can lead to increased political engagement -- but only on specific issues. When there is a general perception of bias in the news media it actually results in increased apathy among citizens.
A single interneuron controls activity adaptively in 50,000 neurons, enabling consistently sparse codes for odors.
A Spanish study has analyzed traffic accidents involving cattle being transported for human consumption in the country for the first time. Despite the "relatively" low mortality rate, animals suffer high-risk situations that cause pain and stress. The scientists say that specific protocols for action are needed with regard to these accidents, and to prepare the emergency services to deal with them.
In the first North American study to examine population rates of emergency department (ED) use for adults with intellectual and developmental disabilities (IDD), researchers from the Institute for Clinical Evaluative Sciences and the Centre for Addiction and Mental Health found 55 per cent of adults with IDD and mental illness visited the ED at least once in a 2 year period and 15.6 per cent visited at least 5 times.
Earlier this year, Boston University researchers and collaborators conducted a mobile greenhouse gas audit in Boston and found hundreds of natural gas leaks under the streets and sidewalks of Greater Boston. Nathan Phillips, associate professor of geography and environment and director of BU's Center for Environmental and Energy Studies, and his research partners will present these and related findings at NOAA's Earth System Research Laboratory Global Monitoring Annual Conference, May 17-18 in Boulder, Colo.
Study finds therapies using induced pluripotent stem cells could encounter immune rejection problems
Biologists at UC San Diego have discovered that an important class of stem cells known as "induced pluripotent stem cells," or iPSCs, derived from an individual's own cells, could face immune rejection problems if they are used in future stem cell therapies.

During a survey on Guyana's Cuyuni River, UTSC researcher Devin Bloom utilized Facebook to help identify thousands of fish specimens in less than 24 hours.
Close your eyes for a moment, open your treasure trove of memories and take a step back in time to your childhood. Do you remember your grandfather gently scooping you up into his warm and comforting embrace? Or sitting by your grandmother's side as she lovingly baked pies chock full of delicious, juicy warm apples sprinkled with crumbly cinnamon bits?
Most people who have had the experience of having pet animals in their houses have the gut feeling that the animals can "recognize" us. They seem to recognize our faces, our voices and our smell. One way or another, they respond to us differently from other people.
States that have certification programs designating primary stroke centers are more likely to have certified stroke centers than those that don't have state-run programs, according to a new study.
