Simulations predict mysterious biological processes of the cell

The research group of Lucie Delemotte, Associate Professor in computational biophysics at the KTH Royal Institute of Technology in Stockholm, Sweden, is focusing on understanding the function of ion channels in cell membranes. ...

Bacteria make a beeline to escape tight spaces

A newly published study by researchers at the University of Hawai'i at Mānoa revealed that bacteria alter their swimming patterns when they get into tight spaces—making a beeline to escape from confinement.

The first cells might have used temperature to divide

A simple mechanism could underlie the growth and self-replication of protocells—putative ancestors of modern living cells—suggests a study publishing September 3 in Biophysical Journal. Protocells are vesicles bounded ...

Deconstructing the infectious machinery of SARS-CoV-2

In February 2020, a trio of bio-imaging experts were sitting amiably around a dinner table at a scientific conference in Washington, D.C., when the conversation shifted to what was then a worrying viral epidemic in China. ...
