New research shows that physical pressure from brain tumors or injuries triggers a "self-destruction" program in neurons, leading to irreversible brain damage.

Cells have a variety of processes and pathways that can repair damage, remove trash and debris, and boost healing. Scientists have now discovered a novel process in which cells eliminate stuff, and ...

Plants are a rich and renewable source of compounds used in medicines, food ingredients, and cosmetics. Since growing an ...

In some mammals, the timing of the normally continuous embryonic development can be altered to improve the chances of survival for both the embryo and the mother. This mechanism to temporarily slow ...

Over the past 15 years, University of Alabama at Birmingham endocrinologist Anath Shalev, M.D., has unraveled a crucial biological pathway that malfunctions in diabetes. Her latest discovery in this ...

Dendritic cells (DCs) are among the first immune sentinels to detect viruses, bacteria, or other challenges. These specialized messengers alert T cells while orchestrating either a measured calm or a ...

Researchers have for the first time identified degeneration-associated “molecular markers” —observable changes in cells and their gene-regulating networks—that are shared by several forms of dementia ...

Plants are a rich and renewable source of compounds used in medicines, food ingredients, and cosmetics. Since growing an entire plant just to extract ...

Plant cell cultures are an attractive alternative to cultivating whole plants for obtaining natural compounds, but many ...
