January 26, 2015 7:00 am | by The Conversation, Tim Trudgian Videos Comments

Fuel prices may be at historic lows at the moment but when they rise again, what is the best strategy to save money at the pump? One theory on how to conserve fuel is to put less of it in your tank. The thinking is that you carry around less weight in the car, which means the engine does not have to work as much, which means saving on fuel.

Lasers Make Metal Surfaces Extremely Water-repellent

January 22, 2015 7:00 am | by Univ. of Rochester Videos Comments

Scientists have used lasers to transform metals into extremely water repellent, or super-hydrophobic, materials without the need for temporary coatings. Super-hydrophobic materials are desirable for a number of applications such as rust prevention, anti-icing or even in sanitation uses. However, most current hydrophobic materials rely on chemical coatings.

Implantable Fibers Deliver Drugs to the Brain

January 21, 2015 7:00 am | by MIT, David Chandler Videos Comments

By producing complex multimodal fibers that could be less than the width of a hair, researchers have created a system that could deliver optical signals and drugs directly into the brain, along with simultaneous electrical readout to continuously monitor the effects of the various inputs.

SpaceX Releases Video of Crash Landing's Explosion

January 20, 2015 8:34 am | by Associated Press Videos Comments

SpaceX has released dramatic footage of its booster rocket trying to land on a floating ocean barge after a launch — an unprecedented attempt that ended in a fiery explosion. The video shows the 14-story rocket hitting the football field-sized barge at an angle, lighting up the night sky off the Florida coast.

Research Sheds Light on How Blood Stem Cells Take Root

January 16, 2015 7:00 am | by Harvard Medical School Videos Comments

A see-through zebrafish and enhanced imaging provide the first direct glimpse of how blood stem cells take root in the body to generate blood. Researchers have described a surprisingly dynamic system that offers several clues for improving bone-marrow transplants in patients with cancer, severe immune deficiencies and blood disorders, and for helping those transplants “take.”

Rain Releases Aerosols

January 15, 2015 7:00 am | by MIT, Jennifer Chu Videos Comments

Ever notice an earthy smell in the air after a light rain? Now, scientists believe they may have identified the mechanism that releases this aroma, as well as other aerosols, into the environment. Using high-speed cameras, the researchers observed that when a raindrop hits a porous surface, it traps tiny air bubbles at the point of contact.

Contracting Human Muscle Grown in Lab

January 14, 2015 7:00 am | by Duke Univ. Videos Comments

In a laboratory first, researchers have grown human skeletal muscle that contracts and responds just like native tissue to external stimuli such as electrical pulses, biochemical signals and pharmaceuticals. The lab-grown tissue should soon allow researchers to test new drugs and study diseases in functioning human muscle outside of the human body.

Rivers on Ice Sheet Contribute to Rising Sea Levels

January 13, 2015 7:00 am | by UCLA Videos Comments

As the largest single chunk of melting snow and ice in the world, the massive ice sheet that covers about 80 percent of Greenland is recognized as the biggest potential contributor to rising sea levels, and the little-understood rivers and streams flowing on top of the ice sheet play a role in that contribution.

Human Brain Prunes Inaccurate Memories

January 12, 2015 7:00 am | by Princeton Univ. Videos Comments

An experiment has shown that the human brain uses memories to make predictions about what it expects to find in familiar contexts. When those subconscious predictions are shown to be wrong, the related memories are weakened and are more likely to be forgotten. And the greater the error, the more likely you are to forget the memory.
