A newly identified protein may hold the key to rejuvenating aging brain cells. Researchers found that boosting DMTF1 can ...

When HHMI Investigator Amita Sehgal started studying sleep 25 years ago, the topic elicited a yawn from most biologists. "In ...

Researchers at the MRC Laboratory of Medical Sciences (LMS) and Imperial College London have shown for the first time that, before they can start developing into egg and sperm cells, the embryonic ...

The Johns Hopkins-created maps provide higher resolution and better coverage of gray matter than previously published maps, ...

Innovations in imaging and genetic engineering are coming together to probe the biophysics of cytoplasm inside living animals.

The brain's ability to carry out everything from forming memories to coordinating movement depends on its cells producing the right proteins at the right time. But directly measuring this protein ...

Water supports major body functions like temperature control, saliva production, joint cushioning, digestion, and waste removal through sweat, urine, and bowel movements. Most people meet hydration ...
