Robots may receive urine-powered artificial 'hearts'

(Phys.org) —It's a first: researchers have built the first artificial-heart-like pump that is powered by microbial fuel cells fed on human urine. But instead of being used as a prosthetic device for human patients suffering ...

Light-activated skeletal muscle engineered (w/ Video)

Many robotic designs take nature as their muse: sticking to walls like geckos, swimming through water like tuna, sprinting across terrain like cheetahs. Such designs borrow properties from nature, using engineered materials ...

Lightning's electromagnetic fields may have protective properties

Lightning was the main electromagnetic presence in the Earth's atmosphere long before the invention of electricity. There are some 2,000 thunderstorms active at any given time, so humans and other organisms have been bathed ...

High vinculin levels help keep aging fruit fly hearts young

Our cells tend to lose their shape as we grow older, contributing to many of the effects we experience as aging. This poses particular problems for the heart, where aging can disrupt the protein network within muscle cells ...

3-D packaging of DNA regulates cell identity

The fundamental mechanisms governing how cells form an identity such as becoming a muscle cell or a nerve cell are not fully understood. Multiple diseases, including cancer, have been linked to cells going down the wrong ...

Light beam replaces blood test during heart surgery

A University of Central Florida professor has invented a way to use light to continuously monitor a surgical patient's blood, for the first time providing a real-time status during life-and-death operations.

Nanostraws sample a cell's contents without damage

Cells within our bodies divide and change over time, with thousands of chemical reactions occurring within each cell daily. This makes it difficult for scientists to understand what's happening inside. Now, tiny nanostraws ...
