Study: Lift weights, improve your memory

October 2, 2014 9:21 am | Videos | Comments

A new Georgia Institute of Technology study shows that an intense workout of as little as 20 min can enhance episodic memory, also known as long-term memory for previous events, by about 10% in healthy young adults. The research isn’t the first to find that exercise can improve memory. But the study took a few new approaches, including testing memory after just single period of exercise.

Research confirms controversial Darwin theory of “jump dispersal”

October 2, 2014 8:22 am | News | Comments

More than one hundred and fifty years ago, Charles Darwin hypothesized that species could cross oceans and other vast distances on vegetation rafts, icebergs, or in the case of plant seeds, in the plumage of birds. Though many were skeptical of Darwin's "jump dispersal" idea and instead supported the idea of the use of land bridges, a new computational method now suggests that Darwin might have been correct.

Stressed out: Research sheds new light on why rechargeable batteries fail

October 2, 2014 8:18 am | by Marcia Goodrich, Michigan Technological Univ. | News | Comments

Drawn relentlessly by their electrical charges, lithium ions in a battery surge from anode to cathode and back again. Yet, no one really understands what goes on at the atomic scale as lithium ion batteries are used and recharged. Using transmission electron microscopy, researchers are now glimpsing what can happen to anodes as lithium ions work their way into them. The “atomic shuffling” these ions perform leads to rapid anode failure.

Study: Nanoparticles accumulate quickly in wetland sediment

October 2, 2014 8:14 am | by Ken Kingery, Duke Univ. | News | Comments

A Duke Univ. team has found that nanoparticles called single-walled carbon nanotubes accumulate quickly in the bottom sediments of an experimental wetland setting, an action they say could indirectly damage the aquatic food chain. According to the research, the risk to humans ingesting the particles through drinking water is slight, but aquatic food chains might be harmed by molecules "piggybacking" on the carbon nanoparticles.

“Stealth” nanoparticles could improve cancer vaccines

October 2, 2014 8:01 am | News | Comments

Cancer vaccines have recently emerged as a promising approach for killing tumor cells before they spread. But so far, most clinical candidates haven’t worked that well. Now, scientists have developed a new way to deliver vaccines that successfully stifled tumor growth when tested in laboratory mice. And the key is in the vaccine’s unique stealthy nanoparticles.

Unexpected new mechanism reveals how molecules become trapped in ice

October 1, 2014 11:34 am | News | Comments

Ice contains many atoms and molecules trapped inside its structure. A team of Univ. of Chicago and Loyola Univ. researchers has discovered a new mechanism they call "stable energetic embedding" of atoms and molecules within ice. This mechanism explains how some molecules, such as CF4, or "carbon tetrafluoride", interact with and become embedded beneath ice surfaces.

Drug delivery capsule may replace injections

October 1, 2014 8:22 am | by Anne Trafton, MIT News Office | Videos | Comments

Given a choice, most patients would prefer to take a drug orally instead of getting an injection. Unfortunately, many drugs, can’t be given as a pill because they get broken down in the stomach before they can be absorbed. To help overcome that obstacle, researchers have devised a novel drug capsule coated with tiny needles that can inject drugs directly into the lining of the stomach after swallowed.
