UCLA scientists have characterized the structure and function of a key survival protein in breast cancer cells that helps ...

When two cells "talk" to each other, they often do so through tiny channels called electrical synapses. Unlike chemical ...

Before cells can divide by mitosis, they first need to replicate all of their chromosomes, so that each of the daughter cells can receive a full set of genetic material. Scientists have until now ...

Inside human cells, biology has pulled off the ultimate packing job, figuring out how to fit six feet of DNA into a nucleus ...

In short, Gould, Garg, and Martin’s hypothesis explains why endomembrane compartments evolved: to solve problems created by the new guest. But it doesn’t fully explain how the alphaproteobacterium got ...

Mitochondria can lose power like batteries, but they can potentially be regenerated—a promising development than can be used in future treatments.

Scientists in Melbourne have discovered how tiny electrical pulses can steer stem cells as they grow, opening the door to new ...

Scientists have created synthetic blobs that resemble a 14-day-old human embryo for the first time, meaning they can study embryo development beyond a particularly tricky period of pregnancy.

Researchers at the Icahn School of Medicine at Mount Sinai have discovered how to reverse aging in blood-forming stem cells in mice by correcting defects in the stem cell's lysosomes. The breakthrough ...
