Molecular 'self-destruct' switch discovered: How stressed cells decide between survival and death
A new study from Ben-Gurion University of the Negev (BGU) has identified a molecular switch that controls whether stressed human cells activate a survival mechanism or trigger programmed cell death (apoptosis). The findings, published in Redox Biology, provide insights that could

Breaking and entering: How parasites prepare host cells for invasion
Before the parasite Toxoplasma gondii can invade a cell, it has to know it has reached the right place. New research from the Whitehead Institute reveals that the parasite doesn't simply recognize a ready-made doorway into the cell. Instead, it helps create the conditions for its

Blood pressure enzyme reveals second job: Making sulfur rings for cellular antioxidants
Antioxidants such as vitamins C and E protect cells by neutralizing free radicals, such as reactive oxygen species, before they can damage genetic material or cell membranes. Such damage can contribute to the development of neurodegenerative diseases. Antioxidants therefore help

Scientists gave worms magnetic bacteria. They lived 43% longer
A magnet-producing bacterium extended the average lifespan of C. elegans worms by more than 43% while helping protect their neurological and intestinal health. Researchers traced much of the effect to suppression of ferroptosis, a damaging form of cell death linked to iron buildu
