Ultrasound aligns living cells in bioprinted tissues

North Carolina State University researchers have developed a technique to improve the characteristics of engineered tissues by using ultrasound to align living cells during the biofabrication process.

New electron microscopy technique limits membrane destruction

Membrane proteins play an important role in many biological processes. Studies suggest they're targeted by more than 50% of all modern medicinal drugs. Unfortunately for researchers, determining their structures has been ...

Catching fast changes in excited molecules

It's hard to see certain molecules react. The reaction is just that fast. Until now. A team of scientists devised a way to reveal time- and energy-resolved information on "dark" states of molecules—ones that are normally ...
