Deep in our cells, a wide range of processes are occurring constantly. These cellular processes rely on enzymes to act as catalysts and set off a series of molecular interactions. There are still many ...

A study on worms led by researchers from Vanderbilt University School of Medicine in the US has uncovered a previously unknown adaptation to aging that actively remodels one of the largest and most ...

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 ...

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 ...

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 ...

Cytochrome c is a pivotal haemoprotein that resides within the mitochondrial intermembrane space, where it fulfils essential roles in cellular respiration and the regulation of apoptosis. Functioning ...

Scientists have transformed RNA, a biological molecule present in all living cells, into a biosensor that can detect tiny chemicals relevant to human health. Research by scientists centers on RNA, a ...

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

An international group of researchers led by Pompeu Fabra University has discovered the nanomachine that controls constitutive exocytosis: the uninterrupted delivery of spherical molecular packages to ...

Graham Johnson, a computational biologist and scientific illustrator at the Allen Institute for Cell Science, recalls fantasizing at a lunch table, more than 15 years ago, about a computer model of a ...
