Viruses attack nearly every living organism on Earth. To do so, they rely on highly specialized proteins that recognize and bind to receptors on the surface of target cells, a molecular arms race that ...

Just like every other creature, bacteria have evolved creative ways of getting around. Sometimes this is easy, like swimming in open water, but navigating more confined spaces poses different ...

In the classic “run-and-tumble” movement pattern, bacteria swim forward (“run”) in one direction and then stop to rotate and reorient themselves in a new direction (“tumble”). During experiments where ...

Scientists have uncovered a new explanation for how swimming bacteria change direction, providing fresh insight into one of biology’s most intensively studied molecular machines. Bacteria move through ...

"The UN estimates that by 2050, common bacterial infections could kill more people than cancer," says Arnold Mathijssen, a biophysicist at the University of Pennsylvania who studies how active ...

How much does life weigh? It sounds like a strange question, but to biologists it makes all the sense in the world. Yeast cells tip the scales at about 100 picograms each. A single E. coli bacterium ...

Your gut is packed with trillions of tiny living things. They help break down food, train the immune system, and even make useful chemicals your body needs. The entire community is known as the gut ...
