Understanding COVID-19 infection and possible mutations

The binding of a SARS-CoV-2 virus surface protein spike—a projection from the spherical virus particle—to the human cell surface protein ACE2 is the first step to infection that may lead to COVID-19 disease. Penn State ...

Molecular forces: The surprising stretching behavior of DNA

When large forces act on a heavy beam, for example, in bridge construction, the beam will be slightly deformed. Calculating the relationship between forces, internal stresses and deformations is one of the standard tasks ...

Decoding the fundamental mechanisms of human salivary lubrication

An interdisciplinary team of scientists led by the University of Leeds have uncovered the fundamental mechanism by which human saliva lubricates our mouth. Their multi-scale study opens the door to advancing dry mouth therapies ...

Rotation on an eight-shaped path

Chemical engineers at Ludwig-Maximilians-Universität (LMU) in Munich, Germany, have developed the first molecular motor that enables an eight-shaped movement.

Performing chemistry in floating droplets

Could chemists be ready to ditch the venerable test tube, the very symbol of chemistry in the minds of many people? Maybe not quite yet, but Caltech's Jack Beauchamp is working on it.

Scientists connect quantum bits with sound over record distances

Scientists with the Institute for Molecular Engineering at the University of Chicago have made two breakthroughs in the quest to develop quantum technology. In one study, they entangled two quantum bits using sound for the ...
