Understanding how autoactivation triggers cell death

Apoptosis is a process that causes cell death. It can go awry in cancer cells, sustaining the disease. Scientists at St. Jude Children's Research Hospital have captured the structure of BAK, a protein that triggers apoptosis. ...

Observing the secret life of molecules inside the cell

To understand how cells function, scientists study how their different components—from single molecules to multiple organelles—work together. Using traditional structural biology techniques, they can look at individual ...

Precision sieving of gases through atomic pores in graphene

By crafting atomic-scale holes in atomically thin membranes, it should be possible to create molecular sieves for precise and efficient gas separation, including extraction of carbon dioxide from air, University of Manchester ...

Researchers film fundamental life process at cellular level

All proteins in a cell are assembled by complicated molecular machines. The precursors of these ribosomes are produced in the cell nucleus and then enter the cell through the so-called nuclear pores. Researchers at the University ...

AI-driven dynamic face mask adapts to exercise, pollution levels

During the coronavirus pandemic, many people have grown accustomed to wearing face masks to protect themselves and others, but that doesn't mean the masks are always comfortable—especially during exercise. Now, researchers ...

Sieving ions with a polymer membrane
