Autistic and non-autistic brain differences isolated for first time

The functional differences between autistic and non-autistic brains have been isolated for the first time, following the development of a new methodology for analysing MRI scans. Developed by researchers at the University...

Recruiting the entire immune system to attack cancer

The human immune system is poised to spring into action at the first sign of a foreign invader, but it often fails to eliminate tumors that arise from the body’s own...

Beyond genes: are centrioles carriers of biological information?

EPFL scientists discover that certain cell structures, the centrioles, could act as information carriers throughout cell generations. The discovery raises the possibility that transmission of biological information could involve more than...

Scientists grow leg muscle from cells in a dish

A team of researchers from Italy, Israel and the United Kingdom has succeeded in generating mature, functional skeletal muscles in mice using a new approach for tissue engineering. The scientists grew...

Scientists discover key driver of human aging

A study tying the aging process to the deterioration of tightly packaged bundles of cellular DNA could lead to methods of preventing and treating age-related diseases such as cancer, diabetes and...

A CRISPR antiviral tool

Emory scientists have adapted an antiviral enzyme from bacteria called Cas9 into an instrument for inhibiting hepatitis C virus in human cells.The results were published April 27, 2015 in Proceedings of...

Temporary Tattoo Offers Needle-Free Way to Monitor Glucose Levels

Nanoengineers at the University of California, San Diego have tested a temporary tattoo that both extracts and measures the level of glucose in the fluid in between skin cells. This first-ever example...

Photovoltaic retinal implant could restore functional sight

A team led by Stanford University researchers has developed a wireless retinal implant that they say could restore vision five times better than existing devices. Results in rat studies suggest it could...

What can brain-controlled prosthetics tell us about the brain?

The ceremonial opening kick of the 2014 FIFA World Cup in Sao Paolo, Brazil, which was performed—with the help of a brain-controlled exo-skeleton—by a local teen who had been paralyzed from...

How the Brain Transforms Sound

Study captures how 2 brain systems in mammals cooperate to capture sounds and process information. When people hear the sound of footsteps or the drilling of a woodpecker, the rhythmic structure...

Optogenetics makes sterile mice fertile again

Researchers have succeeded for the first time in controlling the function of sperm by optogenetics. They inserted a light-activated enzyme for cAMP synthesis into mouse sperm that lacked the endogenous enzyme....

DNA repair map of the entire human genome

When the common chemotherapy drugs cisplatin or oxaliplatin hit cancer cells, they damage DNA so that the cells can't replicate. But the cells have ways to repair the DNA. The cancer...

Brain-machine interface to control prosthetic hand

A research team from the University of Houston has created an algorithm that allowed a man to grasp a bottle and other objects with a prosthetic hand, powered only by his...

Dead feeder cells support stem cell growth

Stem cells naturally cling to feeder cells as they grow in petri dishes. Scientists have thought for years that this attachment occurs because feeder cells serve as a support system, providing...
