All cells need to sense and respond to their environment, to know when to activate genes, build proteins, and carry out their ...

During infection, reversible switch permits flexible formation of memory T cells, long-lived blood cells that can remember pathogen encounters and respond upon reinfection. Unexpected findings have ...

Quantum sensors made from a glowing protein can be produced by living cells and could be used to much more accurately measure tiny changes in the body. This could one day help with early disease ...

A growing body of work suggests that cell metabolism — the chemical reactions that provide energy and building materials — plays a vital, overlooked role in the first steps of life. Each of us starts ...

Billions of years of evolution have made modern cells incredibly complex. Inside cells are small compartments called organelles that perform specific functions essential for the cell’s survival and ...

Researchers around the world are studying how the human brain achieves its extraordinary complexity. A team at the Central ...

Our bodies and organs are shielded from the external environment by tissue barriers like the skin. These barriers must be tightly sealed to prevent unwanted substances from entering. This sealing is ...

The Chan Zuckerberg Initiative is launching a biohub focused on developing new imaging technologies that allow scientists to study the inner workings of living cells. Why it matters: Next-generation ...

Senescence is a process in which a cell ages and stops dividing but does not die. In keratinocytes, or skin cells, senescence is marked by depolarization of membrane potential (Vmem), the electrical ...
