A new study by nine universities and government organizations led by David Sinclair of Harvard Medical School supports the hypothesis that the metabolic benefits of the red wine ingredient known as resveratrol are largely due to its actions on the SIRT1 gene.

University of California San Francisco researchers have learned how neurons fire when orchestrating visual tracking.
They found that individual neurons do not fire independently across the entire duration of a motor function, as has been traditionally thought. Instead, the neurons coordinate their activity with other neurons.
Individual neurons encode different aspects of behavior, sometimes controlling eye-velocity fluctuations, but the entire population of neurons collectively controls the entire movement… read more

How the functioning of X chromosomes differs in women and men may help to explain biological differences between the sexes, according to a new study by researchers from Duke and Pennsylvania State Universities.
The researchers, writing today in the journal Nature, said the results implied that women make higher doses of certain proteins than men, which could result in differences in both normal life and disease.
Women turn… read more

A new study of human intelligence by University of Warwick researchers and associates at nine universities in China and NEC Laboratories America has quantified the brain’s dynamic functions, identifying how different parts of the brain interact with each other at different times, they reported in the journal Brain.
The more variable a brain is, and the more its different parts frequently connect with each other, the higher a… read more

In a study if which people were given a hypothetical pill to make them live longer, 63 percent of participants said there would be personal benefits to life extension, including spending more time with family (36 percent); having more time in life to achieve ambitions (31 percent); and better health and quality of life (21 percent), according to a new study by University of Queensland researchers.
Eighty percent also… read more

Money spent on computing technology delivers gains in worker productivity that are three to five times those of other investments, according to a study being published today. But the study also concluded that the information technology industry itself was unlikely to be a big source of new jobs.

A new study by Mark Changizi, assistant professor of cognitive science at Rensselaer Polytechnic Institute, has uncovered an to binocular vision: our ability to see through clutter.
Changizi says human eyes have evolved to be forward facing, but that we now live in a non-cluttered environment where we might actually benefit more from sideways-facing eyes.

Columbia University Medical Center (CUMC) researchers have found that abnormal tau protein, a key feature of the neurofibrillary tangles seen in the brains of those with Alzheimer’s, propagates along linked brain circuits, “jumping” from neuron to neuron.
The findings open new opportunities for gaining a greater understanding of Alzheimer’s disease and other neurological diseases and for developing therapies to halt its progression, according to senior author Karen… read more

A cloning experiment in mice indicates that for melanoma skin cancer, at least, cancerous cells may be able to revert to normal.
The investigators cloned mouse embryos from a melanoma skin cancer cell. Using embryonic stem cells, they created healthy adult mice who had some cells derived from the cloned cancer cells.

The researchers introduced slow oscillation signals into brain tissue and found that the signal created a sort of feedback loop, with changes in electrical field guiding neural activity, which in turn strengthened the electrical field.
The finding helps explain why techniques that influence electrical fields such as… read more

An analysis of the networks in 46 hotels and survey of 147 U.S. hotels by Cornell’s School of Hotel Administration found that a majority of the hotels do not use all available tools to maintain network security.
For example, about 20 percent of the hotels surveyed still use simple hub-type systems, which are most vulnerable to hacking.
Scientists from The Scripps Research Institute in Florida and the University College London (UCL) Institute of Neurology in England have shown for the first time that abnormal prions, bits of infectious protein that can cause fatal neurodegenerative disease, can suddenly erupt from healthy brain tissue, promoted by contact with steel surfaces.
Mammalian cells normally produce harmless cellular prion protein (PrPC). Following prion infection, the abnormal or misfolded prion protein… read more

New research conducted at The Scripps Research Institute shows that the connectome (the road atlas of the brain) undergoes constant revisions as the brain of a young animal develops, with new routes forming and others dropping away in a matter of hours.
Up until now, researchers had focused their work primarily on determining how new connections form and on finding ways to enhance such formation. But Cline’s findings that… read more

Men and women who eat higher amounts of red meat and processed meat have a higher risk of dying from cancer, heart disease, and other causes compared to those who eat less, according to a new ten-year study by University of North Carolina School of Public Health supported by the National Cancer Institute.
