Muscles are formed by the merging of many small myoblasts into larger myofibers. This fusion of mononucleated myoblasts with a single nucleus into multinucleated myofibers with multiple nuclei is an ...

Science We Support & Eligible Institutions Former Hanna Gray Fellows Choosing a Postdoc (ibiology)external link, opens in a new tab Excellence in science depends on the development of scientists from ...

The structures at the bottom of this image that look like scales are actually bundles of muscles just under the skin of a rabbit. This image is a stained cross section taken under polarized light ...

Enzymes called RNA polymerases transcribe DNA into RNA. RNA is the intermediary that carries the information contained within DNA to the ribosomes, where the genetic information is synthesized into ...

This view into the brain of a locust allows you to see the neurons involved in the processing of scent information. The orange and blue neurons were filled with dye to reveal their beautifully complex ...

This video lets you peek inside the human brain, highlighting the neuronal fibers that enable communication across the brain. This communication is vital to all brain functions, including learning, ...

Serotonin is a biochemical compound that contributes to a variety of important biological functions, including the regulation of mood and emotions. Certain brain cells make serotonin and release it ...

Pyramidal neurons are a very common type of neuron in the brain. Their cell bodies have a unique pyramidal shape that is the source of their name. They make up about two-thirds of all neurons in the ...

Confetti mice are very useful in research because they allow scientists to track which cells produce which proteins based on their color under a fluorescent microscope. These mice are particularly ...

The blue spiral in the center of this field of green and white cells looks as if it might be a seashell. However, it is actually the cochlea of a newborn mouse. The cochlea is an organ in the inner ...

Unlike prokaryotic cells, all eukaryotic cells have nuclei. Nuclei house most of a cell’s genetic information – much of it in the form of DNA – making a nucleus a sort of blueprint for building future ...

This red blood cell is trapped in the traumatized muscle tissue of a soldier receiving treatment for severe muscle damage. Muscle injury is a common problem in sports, military combat, and even daily ...
