Research Key to Cyborg Moth 'Biobots'

August 21, 2014 7:00 am | by North Carolina State Univ. | Videos | Comments

Researchers have developed methods for electronically manipulating the flight muscles of moths and for monitoring the electrical signals moths use to control those muscles. The work opens the door to the development of remotely controlled moths, or “biobots,” for use in emergency response.


Tickling Ears May Aid Heart

August 21, 2014 7:00 am | by Univ. of Leeds | News | Comments

A team of researcher used a standard TENS machine to apply electrical pulses to the tragus, the small raised flap at the front of the ear immediately in front of the ear canal. The stimulation changed the influence of the nervous system on the heart by reducing the nervous signals that can drive failing hearts too hard.


Scientist of the Week: Alan Feduccia

August 21, 2014 7:00 am | by Lily Barback, Associate Editor | News | Comments

Alan Feduccia and Stephen Czerkas found that a birdlike fossil, called a Scansoriopteryx, is not a dinosaur, as previously thought, but much rather the remains of a tiny tree-climbing animal that could glide. Their find challenges the commonly held belief that birds evolved from ground-dwelling theropod dinosaurs that gained the ability to fly.

Have you ever wondered why we give birth to live young rather than lay eggs? Scientists have pondered this for a long time and answers have come from an unlikely source: some of Australia’s lizards and snakes.


Coronary Arteries Hold Heart-regenerating Cells

August 21, 2014 7:00 am | by Vanderbilt Univ. | News | Comments

Endothelial cells residing in the coronary arteries can function as cardiac stem cells to produce new heart muscle tissue, investigators have discovered. The findings offer insights into how the heart maintains itself and could lead to new strategies for repairing the heart when it fails after a heart attack.


Food Waste May Be Turned into Bioplastic

August 21, 2014 7:00 am | by ACS | News | Comments

Your chairs, synthetic rugs and plastic bags could one day be made out of cocoa, rice and vegetable waste rather than petroleum, scientists are now reporting. The novel process they have developed could help the world deal with its agricultural and plastic waste problems.
