Hibernation Mechanism May Help Prevent Alzheimer's

January 16, 2015 7:00 am | by Univ. of Leicester | News | Comments

During hibernation, where a mammal’s core temperature cools to well below normal, the connections between brain cells are depleted. This process may be defective in neurodegenerative diseases such as Alzheimer’s, contributing to the death of brain cells in these disorders. By simulating the effects of cooling in mice, scientists have revealed a possible new target for drugs that could protect against neurodegeneration.

Method Produces Hydrogen, Syngas Fuel Feedstock

January 16, 2015 7:00 am | by North Carolina State Univ. | News | Comments

A team of chemical engineering researchers has developed a technique that uses a new catalyst to convert methane and water into hydrogen and a fuel feedstock called syngas with the assistance of solar power. The catalytic material is more than three times more efficient at converting water into hydrogen gas than previous thermal water-splitting methods.

Study Looks to Improve Fuel Cells for Emissions-free Cars

January 16, 2015 7:00 am | by Univ. of Delaware | News | Comments

Hydrogen fuel cells may be the best option for powering zero-emission vehicles. But these fuel cells require an electrocatalyst— a platinum surface— to increase the reaction rate, and the cost of the precious metal makes it hard for hydrogen fuel cells to compete economically with the internal combustion engine.

How Is Oil Cheap When We Use So Much?

January 16, 2015 7:00 am | by Associated Press, Jonathan Fahey | News | Comments

The world burns enough oil-derived fuels to drain an Olympic-sized swimming pool four times every minute. Global consumption has never been higher— and is rising. Yet, the price of a barrel of oil has fallen by more than half over the past six months because the globe, experts say, is awash in oil.

Flu Vaccine is 23 Percent Effective

January 15, 2015 3:00 pm | by Associated Press, Mike Stobbe | News | Comments

As predicted, this year's flu vaccine is doing a pretty crummy job. Health officials say a new study shows it's only 23 percent effective. That's one of the worst performances since the government started tracking how well vaccines work a decade ago.

Excess Iron Promotes Aging

January 15, 2015 3:00 pm | by Buck Institute for Age Research | News | Comments

It's been known for decades that some metals, including iron, accumulate in human tissues during aging. Common belief has held that iron accumulation happens as a result of the aging process. But, research shows that iron accumulation itself may also be a significant contributor to the aging process, causing dysfunction and malfolding of proteins already implicated in the aging process.

July 16, 1945 Started Current Epoch

January 15, 2015 3:00 pm | by Univ. of Leicester | News | Comments

Humans are having such a marked impact on the Earth that they are changing its geology, creating new and distinctive strata that will persist far into the future. Scientists have proposed a start date for the dawn of the Anthropocene— a new chapter in the Earth's geological history. It began July 16, 1945: the day of the world’s first nuclear test.

You Can Be Hacked While Offline

January 15, 2015 3:00 pm | by Inside Science News Service, Ker Than | News | Comments

Hackers equipped with little more than a cheap radio antenna could spy on your digital activities by monitoring the electronic signals your computer produces during the course of its normal operations. Even disconnecting from the Internet won’t help protect you from this kind of so-called “side channel” attack, and your smartphone may be even more vulnerable, experts say.
