Study to Test 'Chocolate' Pills for Heart Health

March 17, 2014 2:16 am | by Marilynn Marchione - AP Chief Medical Writer - Associated Press | News | Comments

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.                 

Breaking News: Forgetting is Actively Regulated

March 13, 2014 12:00 pm | News | Comments

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.

Breaking News: New Gene for Bipolar Discovered

March 11, 2014 12:00 pm | News | Comments

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.                     


Higher Levels of Omega-3 in Diet Associated with Better Sleep

March 6, 2014 2:36 pm | News | Comments

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.

Prevalence of Allergies the Same, Regardless of Where You Live

DNA Blood Tests Show Prenatal Screening Promise

February 26, 2014 5:17 pm | by Marilynn Marchione - AP Chief Medical Writer - Associated Press | News | Comments

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.        

Different Eggs in Adolescent Girls and Adult Women

February 26, 2014 2:29 pm | News | Comments

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”.


Breast-feeding Benefits Appear to be Overstated, According to Study of Siblings

February 26, 2014 1:58 pm | News | Comments

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.

Research Team Discovers Disease-Causing Bacteria in Dental Plaque Preserved for 1,000 Years

February 24, 2014 12:56 pm | News | Comments

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 Bone Healing

February 19, 2014 1:54 pm | by Cynthia Fox | Articles | Comments

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.

February 13, 2014 2:15 pm | News | Comments

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.                     

Breaking News: Gene Links Brain Structure to Intelligence

February 11, 2014 9:19 am | News | Comments

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.      


A Microchip for Metastasis

February 7, 2014 11:32 am | News | Comments

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.         

WADA to Resume HGH Testing, 'Outraged' by New Drug

February 7, 2014 11:19 am | by Graham Dunbar, Associated Press | News | Comments

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.

New Evidence Shows Increase in Obesity May be Slowing, But Not by Much

February 6, 2014 12:00 pm | News | Comments

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.

Biologic Agents Provide Relief for Children Newly Diagnosed with Crohn’s Disease

February 4, 2014 11:43 am | News | Comments

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.

February 3, 2014 6:07 pm | by Lindsey Tanner - AP Medical Writer - Associated Press | News | Comments

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.
