Nano fiber feels forces and hears sounds made by cells

Engineers at the University of California San Diego have developed a miniature device that's sensitive enough to feel the forces generated by swimming bacteria and hear the beating of heart muscle cells.

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.

Seeing the world through fresh eyes

There are many different structures in our eyes that work in conjunction to allow us to see. These structures are strikingly similar between different species, from zebrafish to humans. The growth of ocular tissues must be ...

New microfluidic chip replicates muscle-nerve connection

MIT engineers have developed a microfluidic device that replicates the neuromuscular junction—the vital connection where nerve meets muscle. The device, about the size of a U.S. quarter, contains a single muscle strip and ...

Scientists solved the Spallanzani's dilemma

Imagine losing an eye, an arm or even your spinal cord. When we are wounded, our bodies, and those of other mammals, generally respond by sealing the wound with scar tissue. The newt, however, has evolved unique strategies ...

Learning how muscle cells feel the pull of gravity

People can easily feel the presence - or absence - of gravity. Our individual cells actually may be able to sense gravity, too, and that ability could play a role in the loss of muscle that occurs when humans spend time in ...

Decoding cell division's mysterious spindle matrix

Every high school biology class learns about the tiny cells that comprise our bodies, as well as about many of the diverse actions that they perform. One of these actions is called mitosis, the series of steps through which ...
