Blood cells converted to stem cells in 30 minutes


A simple idea could be a game changer for stem cell research, after a Japanese team found a way to change blood cells into stem cells in only 30 minutes.

Implantable device generates power indefinitely.


Implanted devices such as pacemakers have traditionally relied on battery power to function, requiring surgery every time the battery is to be replaced. Now a joint US/Chinese team have developed a device able to generate enough power to potentially keep such devices powered indefinitely, using a

Google’s smart contact lens shown off


Google have announced in a blog post their work to develop a contact lens with “chips and sensors so small they look like bits of glitter, and an antenna thinner than a human hair”.


Credit card sized chip quickly diagnoses HIV.

The fluid processing chip works in a battery powered hand held device, and is designed to work in any part of the world for a quick, on-the-spot diagnosis, in less than 20 minutes.

Once in mass production, it is expected the reader would cost less than $1000, and each testing chip less than $10.

Scientists make ‘bullets’ out of light.


A European team has found a way to create beams of light that focus more intensely as they travel, forming what looks like a bullet out of light.

Maggot-bots proposed for brain surgery


University of Maryland researchers are developing a maggot-like robot that could crawl into a human brain to zap tumors, while the patient is in an MRI machine.


Terahertz radiation could detect early signs of skin cancer


The same type of terahertz radiation which is finding its way into uses such as airport body scanners could also be used to detect melanoma before it even appears visible to the human eye, at its earliest and most treatable stage.
