This influx of calcium at the contact site attracts and activates a kinase called CaMKII, a protein known to be important in ...

A complex molecular machine, the spliceosome, ensures that the genetic information from the genome, after being transcribed into mRNA precursors, is correctly assembled into mature mRNA. Splicing is a ...

New research reveals that brain cells use a muscle-like signaling mechanism to relay information over long distances.

Innovative muscle patches derived from stem cells demonstrate efficacy in heart repair, improving function in primates and a ...

A kidney cancer cell nucleus is studded with aberrant nuclear speckles (orange). Normal healthy cells tend to have the speckles clustered toward the middle. Image credit: Kate Alexander (Cold Spring ...

Skeletal muscle is composed of fascicles, bundled units of multiple muscle fibers or muscle cells. Each muscle fiber consists of a cross-banded structure that is further divided into myofibrils that ...

Way back in 1830 mysterious specks were seen by early microscopists inside the cell nucleus. Then called nucleoli, they were later found to be where the ribosome is made. But it wasn’t until ...

If your health goals include building muscle while losing fat and excess weight, you may wonder if you can build muscle while in a calorie deficit (when you eat fewer calories than your body uses).

Nuclear pore complexes are the guardians of the human genome that is packaged into the nucleus of all cells. They form selective channels through the envelope of the nucleus and connect its ...
