Prisoners who are psychopaths lack the basic neurophysiological “hardwiring” that enables them to care for others, according to a new study by neuroscientists at the University of Chicago and the University of New Mexico. (more…)
Like finally seeing all the gears of a watch and how they work together, researchers from UCLA and UC Berkeley have, for the first time ever, solved the puzzle of how the various components of an entire telomerase enzyme complex fit together and function in a three-dimensional structure.
The creation of the first complete visual map of the telomerase enzyme, which is known to play a significant role in aging and most cancers, represents a breakthrough that could open up a host of new approaches to fighting disease, the researchers said. (more…)
The adolescent age is very much critical phase of life. Every teenage girl and boy when they enter in this age tends to behave differently, which has to be understood very well by the parents, elders and teenagers. This can help everyone including the teenager to grow in a healthy atmosphere, which can help them to imbibe positive values in their lives along with averting them to tread wrong paths. If you fail to understand people of this age, you may end up seeing your adolescent boy or girl going in a wrong direction. Hence knowing the dos and don’ts are important both for parents and teenagers as well. Let’s check out the do’s and don’ts evident in this critical phase of life. (more…)
UCLA researchers have used a brain-imaging tool and stroke risk assessment to identify signs of cognitive decline early on in individuals who don’t yet show symptoms of dementia.
The connection between stroke risk and cognitive decline has been well established by previous research. Individuals with higher stroke risk, as measured by factors like high blood pressure, have traditionally performed worse on tests of memory, attention and abstract reasoning. (more…)
The potential of gene therapy to boost heart muscle function was explored in a recent University of Washington animal study. The findings suggest that it might be possible to use this approach to treat patients whose hearts have been weakened by heart attacks and other heart conditions.
Michael Regnier, UW professor and vice chair of bioengineering, Charles Murry, director of the Center for Cardiovascular Biology and co-director of the Institute for Stem Cell and Regenerative Medicine, and Sarah Nowakowski, a UW graduate student in bioengineering, led the study. The findings appeared online March 25 in the Proceedings of the National Academy of Sciences. (more…)
Type 1 diabetes is a condition in which the body does not produce insulin and cannot convert sugar, starches and other food into energy. Generally diagnosed during childhood or adolescence, the disease requires lifelong access to medical care and intensive daily self-management.

We know the benefits of laughter on health. But why do we laugh? What are the evolutionary origins of laughter and humour? Steven Légaré has asked these questions and has made them the subject of his master’s thesis, which he recently submitted to the Université de Montréal’s Department of Anthropology.
“Science provides few answers to these questions other than in psychology and neuroscience. From the perspective of anthropology, laughter and humour are often overlooked. However, it is a serious subject,” says the recent graduate. (more…)
A genetic pathway involving proteins in the endosomes of cells appears to be misregulated in the brains of children with autism, according to a newly published statistical analysis in the journal Molecular Psychiatry. Previously the genes were shown to cause rare forms of the disease but the new study suggests they have a wider role.
PROVIDENCE, R.I. [Brown University] — A new study finds that two genes individually associated with rare autism-related disorders are also jointly linked to more general forms of autism. The finding suggests a new genetic pathway to investigate in general autism research. (more…)
