Giant viruses build a cell nucleus surprisingly like our own

Humans aren't the only targets for viruses. Like us, bacteria become infected by many types of viruses. In fact, across billions of years, bacteria and viruses have engaged in a non-stop evolutionary arms race for survival ...

Mechanism of bacterial toxins in deadly attacks

Only one thousandth of a milligram of the bacterial botulinum toxin is necessary to kill a living organism. The toxin unfolds its lethal effect by preventing the release of neurotransmitters at the point where nerve cells ...

Research reveals the science behind this plant's blue berries

On a beautiful fall day in 2019, Miranda Sinnott-Armstrong was walking down Pearl Street in Boulder, Colorado when something caught her eye: a small, particularly shiny blue fruit, on a shrub known as Lantana strigocamara. ...

Puzzling out the structure of a molecular giant

Combining AlphaFold2 with experimental and computational techniques has helped scientists figure out the human nuclear pore complex's architecture in greater detail than ever before.

Human membrane proteins strike evolutionary balance

Cells are compartmentalized by membranes, and proteins present in these membranes play an important role in transporting cellular information. For proper function of these proteins to occur, a tertiary protein structure must ...
