First map of imprinted genes in human genome

Scientists at Duke University have created the first map of imprinted genes throughout the human genome, and they say a modern-day Rosetta stone – a form of artificial intelligence called machine learning – was the key to their success.

Brain patterns of former anorexics reveal clues to disorder's lasting impact

Even after more than a year of maintaining a normalized body weight, young women who recovered from anorexia nervosa show vastly different patterns of brain activity compared to similar women without the eating disorder, Walter H. Kaye, M.D., professor of psychiatry, University of Pittsburgh School of Medicine, and colleagues report in the December issue of the American Journal of Psychiatry.

Neuromuscular consequences of reflexive covert orienting

The person you're speaking with may be looking at you, but are they really paying attention? Or has the person covertly shifted their attention, without moving their eyes? Dr. Brian Corneil, of the Centre for Brain and Mind at The University of Western Ontario in London, Canada has found a way of actually measuring covert attention.

Eltrombopag studied in Idiopathic Thrombocytopenic Purpura

There are estimated to be between 50,000 -- 100,000 individuals in the U.S. diagnosed with chronic Immune Thrombocytopenic Purpura (ITP), an autoimmune disease that dramatically reduces the number of platelets in their blood -- causing bruises, nosebleeds and, sometimes, life-threatening brain hemorrhages.

Researchers find evidence of mature heart cell potential in embryonic stem cells

In a new study, UC Davis researchers report the first functional evidence that heart cells derived from human embryonic stem cells exhibit one of the most critical properties of mature adult heart cells, an important biological process called excitation-contraction coupling.

Stem cells train heart following heart attack

Following a heart attack, part of the heart tissue dies. It is still not possible to restore the scar tissue arising as a result of this. The majority of stem cell researchers attempt to make new heart muscle cells from stem cells.
