By simulating the life cycle of a minimal bacterial cell—from DNA replication to protein translation to metabolism and cell ...

Strokes lead to irreversible damage to the brain and are one of the most common causes of dependency or death. As the cellular reactions to a cerebral infarction are not yet fully understood, there is ...

Septins are a conserved family of GTP-binding proteins that assemble into filamentous structures, earning them recognition as the fourth component of the cytoskeleton alongside actin, microtubules and ...

A buildup of a structural protein called F-actin inside aging brain cells appears to cripple the cellular waste-clearing machinery that keeps neurons healthy, according to a study in Drosophila fruit ...

Caspases are a family of proteolytic enzymes that play a central role in apoptosis, the regulated process of programmed cell death essential for development, homeostasis and the clearance of damaged ...

Researchers at UC Merced used fruit flies to uncover a cellular process common to many organisms that could dramatically impact the understanding of cancer and aging. Department of Molecular and Cell ...

Dopamine is a key neurotransmitter known to modulate motivation and reinforcement learning. While the role of dopamine in these reward-related processes is well-established, the cellular and neural ...

Some genetic mutations that are expected to completely stop a gene from working surprisingly cause only mild or even no symptoms. Researchers in ...

Early mammalian ancestors were nocturnal, sleeping during the day while the dinosaurs dominated the land. However, some mammalian lineages, including human ancestors, independently transitioned to ...

Researchers say certain herbs and spices may help protect cells from damage and slow some biological processes linked to aging.

Plants and trees may seem pretty passive, but behind the scenes, their cells are working hard to put on a magic show. In this episode of Crash Course Botany, we’ll explore how the processes of ...
