What makes someone a "morning lark" or a "night owl?" Why does jet lag hit us so hard, and why do some people struggle each ...

A Cedars-Sinai study has identified a previously unknown role for astrocyte cells in how the brain responds to damage and disease. Cedars-Sinai researchers have identified a biological repair process ...

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 ...

Red blood cells transport oxygen throughout your body, including to vital organs and tissues. They also help your body get rid of carbon dioxide. Too little or too many red blood cells may be ...

The immune cell repertoire is composed of many different cell types that are orchestrated in response to infection and other pathogens that enter the body. As a result, the body can defend itself ...

As people age, their immune system function declines. T cell populations become smaller and can't react to pathogens as ...

Taken together, these advances suggest that part of age-related immune decline is driven by specific, potentially reversible ...

Unlike our organs, cell organelles such as mitochondria are not fixed in place, but when, where, how, and why organelles move ...

Moreover, bulk sequencing data led scientists to conclude that brown and beige fat cells express uncoupling protein 1 (Ucp1), which encodes the protein UCP1 that halts adenosine triphosphate (ATP) ...
