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 ...

Researchers develop 'living diode' using cardiac muscle cells

Scientists are one step closer to mimicking the way biological systems interact and process information in the body - a vital step toward developing new forms of biorobotics and novel treatment approaches for several muscle-related ...

Stay out, stray stem cells

Despite the hubbub about pluripotent stem cells' potential applications, when it comes time to introduce products into patients, the stem cells are actually impurities that need to be removed.

Team screens cardiac drugs that also attack cancer

Several drugs now being used to treat heart failure and atrial arrhythmia also show promise as DNA disruptors in cancer cells and could be readily repurposed as anticancer agents, according to a new study by Yale researchers.

Team develops targeted photosensitizer for cell manipulation

Researchers led by Carnegie Mellon University's Molecular and Biosensor Imaging Center (MBIC) Director Marcel Bruchez have re-engineered a fluorescent probe into a powerful optogenetic photosensitizer that can be used to ...

Collaborative research reveals a new view of cell division

Basic research into the mechanisms of cell division, using eggs and embryos from frogs and starfish, has led researchers to an unexpected discovery about how animal cells control the forces that shape themselves.

Voltage tester for beating cardiac cells

For the first time, scientists have succeeded in recording the current in membrane channels of contracting cardiac cells. To do this, the scientists combined an atomic force microscope with a widely used method for measuring ...
