Rutgers researchers have discovered a new mechanism that may contribute to Alzheimer’s disease and traumatic brain injury. They now hope to launch a clinical trial to test the treatment in humans. What causes Alzheimer’s is unknown, but a popular theory suggests a protein known as amyloid-beta slowly builds up a plaque in the brains of […]
Africa is experiencing a demographic and nutrition transition. More and more people are moving to urban areas. Slum communities currently constitute about 56% of the urban population in sub-Saharan Africa. That’s more than 200 million people, more than the entire population of Nigeria. Even as under-nutrition or not getting enough calories and nutrients – continues […]
MONDAY, Sept. 24, 2018 — Exercising on a budget can be as simple as buying a good pair of walking shoes. But when you want to make an investment in fitness equipment, new options can make your workouts interactive as well as high-energy. Look for exercise bikes, treadmills and ellipticals that offer pre-set workouts, often […]
In the brain, as in business, connections are everything. To maintain cellular associates, the outer surface of a neuron, its membrane, must express particular proteins—proverbial hands that reach out and greet nearby cells. And, like a creepily long handshake, surface molecules can overstay their welcome: A protein that lingers too long on the membrane may […]
Sixty-year-old Emma Zhakata winces, struggling to hold back tears as she relates how her husband, one of 32 cholera victims in Zimbabwe, died within hours of falling ill. She never suspected her 69-year-old husband, Wonder Zhakata, would die suddenly after complaining that he felt weak and was suffering stomach pain. After she rushed her husband […]
Researchers have made a significant new discovery concerning the signaling mechanisms that enable newts to regrow their tails after injury. Specifically, this process is shown to require the coordinated activation of the Hedgehog (Hh) and Wnt pathways. The study is published in Stem Cells and Development. Mary G. Garry, Daniel J. Garry, and colleagues from […]
Carbon monoxide (CO), like many gases, cannot be detected by our human senses. We cannot see it, smell it or taste it. But unlike many gases, small amounts are extremely harmful to us. In 2015 (the most recent year for which statistics are available), 53 people in the UK died from accidental carbon monoxide poisoning. […]
As early as the fourth grade, girls perform better than boys on standardized tests in reading and writing, and as they get older that achievement gap widens even more, according to research published by the American Psychological Association. “The common thinking is that boys and girls in grade school start with the same cognitive ability, […]
Brains of baby boys born prematurely are affected differently and more severely than premature infant girls’ brains. This is according to a study published in the Springer Nature-branded journal Pediatric Research. Lead authors Amanda Benavides and Peg Nopoulos of the University of Iowa in the US used magnetic resonance imaging (MRI) scans as part of […]
Stress demands the heart to work harder and faster. To keep pace, the muscle must make its fuel at an accelerated rate. Bursts of calcium entering mitochondria—the cell’s powerhouses—normally help control energy output, but too much calcium can overload the system and lead to cell death. Now research led by Jefferson (Philadelphia University + Thomas […]
