Study resolves controversy on life-extending, anti-aging resveratrol

May 2, 2012


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.

“Resveratrol improves the health of mice on a high-fat diet and increases life span,” said David Sinclair of Harvard Medical School. The… read more

Study reveals how neurons generate movement

April 25, 2008

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

Study Reveals New Difference Between Sexes

March 17, 2005

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

Study reveals new measure of intelligence involving temporal variability of brain areas

Results could be applied to building advanced deep neural networks and treating mental-health patients

Whole-brain temporal (time) variability is high in areas associated with intelligence and low in sensory cortices (credit: Jie Zhang et al./Brain)

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

Study reveals people’s thoughts on living longer

December 1, 2009

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

Study Says Computers Give Big Boosts to Productivity

March 13, 2007

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.

Study says eyes evolved for X-Ray vision

September 1, 2008

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.

Study shows Alzheimer’s disease may spread by ‘jumping’ from one brain region to another

February 6, 2012


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

Study Shows Cancer Cells May Revert

August 2, 2004

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.

Study Shows Electrical Fields Influence Brain Activity

July 15, 2010


Electrical fields can influence the activity of neurons, Yale scientists report in the July 15 issue of the journal Neuron.

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

Study shows hotels’ Internet connections unsafe

October 2, 2008

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.

Study shows infectious prions can arise spontaneously in normal brain tissue

July 27, 2010

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

Study shows map of brain connectivity changes during development

January 27, 2011

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

Study Shows Perception Of Invisible Stimuli Improves With Training

October 22, 2009

A new study at Max Planck Institute for Brain Research reveals that our brains can be trained to consciously see stimuli that would normally be invisible.

Study Shows Red Meat Consumption Linked to Higher Risk of Dying From Cancer, Heart Disease

March 25, 2009

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.

Possible reasons:

  • The meats are a source of carcinogens formed during cooking.
