It won't be nearly as much fun as eating candy bars, but a big study is being launched to see if pills containing the nutrients in dark chocolate can help prevent heart attacks and strokes.
Through memory loss, unnecessary information in the brain is deleted and the nervous system retains its plasticity. Previously, it was not clear if this process was active or passive, but scientists have now discovered a molecular mechanism that actively regulates the process of forgetting.
An international group of researchers discovered two new gene regions which are connected with bipolar disorder. They were also able to confirm three additional suspect genes.
A randomized placebo-controlled study by the University of Oxford suggests that higher levels of omega-3 DHA, the group of long-chain fatty acids found in algae and seafood, are associated with better sleep. The researchers explored whether 16 weeks of daily 600mg supplements of algal sources would improve the sleep of 362 children.
In the largest, most comprehensive, nationwide study to examine the prevalence of allergies from early childhood to old age, scientists from the National Institutes of Health report that allergy prevalence is the same across different regions of the United States, except in children 5 years and younger.
In two new studies, the so-called “obesity hormone” leptin and hormones used for birth control are being examined for their potential role in the development of multiple sclerosis (MS).
A DNA test of a pregnant woman's blood is more accurate than current methods of screening for Down syndrome and other common disorders, new research finds. If other studies bear this out, it could transform prenatal care.
Are the eggs produced by adolescent girls the same as the ones produced by adult women? A recent study published in Human Molecular Genetics by Professor Kui Liu from the University of Gothenburg in Sweden shows compelling evidence that there are two completely distinct types of eggs in the mammalian ovary—“the first wave” and “the adult wave”.
A new study comparing siblings who were fed differently during infancy suggests that breast-feeding might be no more beneficial than bottle-feeding for 10 of 11 long-term health and well-being outcomes in children age 4 to 14. The outlier was asthma, which was associated more with breast-feeding than with bottle-feeding.
When a University of Oklahoma researcher and an international team of experts analyzed the dental calculus or plaque from teeth preserved for 1,000 years, the results revealed human health and dietary information never seen before. The team discovered disease-causing bacteria in a German Medieval population, which is the same or very similar to inflammatory disease-causing bacteria in humans today.
Binge drinking impairs the healing of broken bones. It can do this weeks after a binge. And it can leave in its wake permanently inferior bone, according to recent studies. One reason: alcohol slows down mesenchymal (bone, fat, and cartilage) stem cells (MSCs), in the bloodstream, trying to home to fracture sites. And when MSCs finally reach fracture sites, alcohol keeps them from properly replacing lost cells.
A new interactive map details the histories of genetic mixing between each of the 95 populations across Europe, Africa, Asia and South America spanning the last four millennia.
For the first time, scientists have identified a gene linking the thickness of the grey matter in the brain to intelligence, which may help scientists understand biological mechanisms behind some forms of intellectual impairment.
In an attempt to learn how and why certain cancers spread to specific organs, researchers have developed a three-dimensional microfluidic platform that mimics the spread of breast cancer cells into a bonelike environment.
Testing for HGH, including samples from Sochi Olympic athletes, should resume after being stalled by an appeal case ruling last year, WADA director-general David Howman said. WADA also said it was "totally outrageous" that a Russian scientist reportedly offered to sell a potent and undetectable new muscle-building drug to undercover journalists. The substance, known as full size MGF, has only been trialed on animals.
In his 2014 State of the Union address, President Obama referred to an August 2013 CDC study that showed a decline in the obesity rate among low-income preschool children. While the CDC report’s data is encouraging, a new study published by University of Illinois kinesiology and community health professor Ruopeng An shows the notion that the American obesity epidemic has begun to reverse may be premature.
A man from Denmark was the first amputee in the world to experience feeling real-time, sensory-rich information with a prosthetic hand wired to nerves in his upper arm.
Children newly diagnosed with Crohn’s disease may benefit from early treatment with the biologic drugs known as anti-TNF-α agents. Researchers compared the effectiveness of early (within three months after diagnosis) treatment with anti-TNF-α inhibitors, compared with early treatment with immunomodulatory drugs, in attaining clinical remission and facilitating growth in children with Crohn's disease.
Could too much sugar be deadly? The biggest study of its kind suggests the answer is yes, at least when it comes to fatal heart problems. It doesn't take all that much extra sugar, hidden in many processed foods, to substantially raise the risk, the researchers found, and most Americans eat more than the safest amount.
In a study to be presented on Feb. 6 at 3 p.m. CST, at the Society for Maternal-Fetal Medicine’s annual meeting, The Pregnancy Meeting, in New Orleans, researchers will report that women ages 35 and older are at a decreased risk of having a child with a major congenital malformation, after excluding chromosomal abnormalities.
Football helmets can be designed to reduce the risk of concussions, according to a new study that analyzed head impact data compiled from eight collegiate football teams that included Virginia Tech, University of North Carolina, University of Oklahoma, Dartmouth College, Brown University, University of Minnesota, Indiana University, and University of Illinois.
Next time you call someone a Neanderthal, better look in a mirror. Many of the genes that help determine most people's skin and hair are more Neanderthal than not, according to two new studies that look at the DNA fossils hidden in the modern human genome.
How aging affects communication between neurons is not well understood, a gap that makes it more difficult to treat a range of disorders, including Alzheimer’s and Parkinson’s disease. A new study from the Florida campus of The Scripps Research Institute (TSRI) offers insights into how aging affects the brain’s neural circuitry, in some cases significantly altering gene expression in single neurons.
Living cells are ready for their close-ups, thanks to a new imaging technique that needs no dyes or other chemicals, yet renders high-resolution, three-dimensional, quantitative imagery of cells and their internal structures.
A new study shows that humans are able to smell sickness in someone whose immune system is highly active within just a few hours of exposure to a toxin. The researchers say there is anecdotal and scientific evidence suggesting that diseases have particular smells.
