Getting a grip on robotic grasp: New wrist-mounted device augments the human hand with two robotic fingers

Posted: 18 Jul 2014 06:57 AM PDT

Twisting a screwdriver, removing a bottle cap, and peeling a banana are just a few simple tasks that are tricky to pull off single-handedly. Now a new wrist-mounted robot can provide a helping hand -- or rather, fingers. Researchers have developed a robot that enhances the grasping motion of the human hand.

Lunar pits could shelter astronauts, reveal details of how 'man in the moon' formed

Posted: 17 Jul 2014 03:04 PM PDT

While the moon's surface is battered by millions of craters, it also has over 200 holes -- steep-walled pits that in some cases might lead to caves that future astronauts could explore and use for shelter, according to new observations.

New gene discovered that stops spread of deadly cancer: Scientists identify gene that fights metastasis of a common lung cancer

Posted: 17 Jul 2014 09:45 AM PDT

A gene responsible for stopping the movement of cancer from the lungs to other parts of the body has been discovered by researchers, indicating a new way to fight one of the world's deadliest cancers. By identifying the cause of this metastasis, which often happens quickly in lung cancer and results in a bleak survival rate, scientists are able to explain why some tumors are more prone to spreading than others. The newly discovered pathway may also help researchers understand and treat the spread of melanoma and cervical cancers.

Transplanting gene into injured hearts creates biological pacemakers

Cardiologists have developed a minimally invasive gene transplant procedure that changes unspecialized heart cells into "biological pacemaker" cells that keep the heart steadily beating.

Mutation stops worms from getting drunk

Posted: 15 Jul 2014 06:43 PM PDT

Neuroscientists have generated mutant worms that do not get intoxicated by alcohol, a result that could lead to new drugs to treat the symptoms of people going through alcohol withdrawal. The scientists accomplished this feat by inserting a modified human alcohol target into the worms.

Dodos and spotted green pigeons are descendants of an island hopping bird

The mysterious spotted green pigeon was a relative of the dodo, according to scientists who have examined its genetic make-up. The authors say their results support a theory that both birds are descended from 'island hopping' ancestors.

Extending Moore's Law: Shrinking transistor size for smaller, more efficient computers

Posted: 15 Jul 2014 01:59 PM PDT

Over the years, computer chips have gotten smaller thanks to advances in materials science and manufacturing technologies. This march of progress, the doubling of transistors on a microprocessor roughly every two years, is called Moore's Law. But there's one component of the chip-making process in need of an overhaul if Moore's law is to continue: the chemical mixture called photoresist. In a bid to continue decreasing transistor size while increasing computation and energy efficiency, chip-maker Intel has partnered with researchers to design an entirely new kind of resist.

Anti-gravity Effect? Gravitational Equivalent Of A Magnetic Field Measured In Lab

Posted: 25 Mar 2006 08:21 PM PST

Scientists funded by the European Space Agency have measured the gravitational equivalent of a magnetic field for the first time in a laboratory. Under certain special conditions the effect is much larger than expected from general relativity and could help physicists to make a significant step towards the long-sought-after quantum theory of gravity.
