A common claim holds that the human body contains ten times as many bacterial cells as human ones, a striking figure repeated ...

It is a fact that reliably startles anyone who hears it for the first time: the human body is home to at least as many ...

The cells of our body are frequently exposed to hazards that can damage them, cause them to malfunction or kill them. Yet ...

During infections, the immune system needs to distinguish foreign antigens that are expressed by invading bacteria and viruses from self-antigens that are expressed by cells of the body. If not, the ...

Our body consists of ~30 trillion cells. These cells need to tightly attach to each other to maintain the integrity of our body. However, we are constantly exposed to mechanical stress, which ...

A billion-year-old calcium signaling system in cyanobacteria reveals surprisingly ancient roots of cell-to-cell communication ...

Researchers have created an early map of some of the human body's estimated 37.2 trillion cells. Each type of cell has a unique role, and knowing what all the cells do can help scientists better ...

Scientists found that embryonic skin cells “whisper” through faint mechanical tugs, using the same force-sensing proteins that make our ears ultrasensitive. By syncing these micro-movements, the cells ...

New research shows how a specially trained population of immune cells keeps the peace by preventing other immune cells from attacking their own. The study provides a better understanding of immune ...
