Despite what’s written in textbooks, fruit flies use a similar cell-stress sensor as mammals to initiate programmed cell death. Contrary to established understanding, RIKEN researchers…
In our bodies, millions of cells meet their end on a daily basis. Contrary to popular belief, cells don’t just explode when they die. Instead,…
A new study has revealed how respiratory supercomplexes, consisting of four associated respiratory complexes, shape the mitochondrial membrane in the single-cell eukaryote, Tetrahymena thermophila. The…
Researchers at the University of Cologne have found that a protein complex impedes the repair of genomic damage in human cells, mice, and the nematode…
A new study has overturned the notion that microproteins, small proteins previously deemed unimportant, play no significant role in human cellular functions. The research, led…
Scientists show that so-called senescent cells, i.e., cells that have permanently stopped dividing, boost production of new muscle cells to enhance regeneration of lost limbs…
For the first time, researchers have found a complex of proteins that contains the four central components for optimized energy production. This discovery is of…
Researchers have demonstrated that biological aging can accelerate under stress but also decelerate when stressors are removed, using a mouse model and human stress cohorts….
Cells possess a remarkable ability to organize their interiors using minuscule protein machines known as molecular motors, which generate directed motion. Most molecular motors rely…
Scientists at UC San Diego have discovered that stem cells’ unique method of discarding misfolded proteins could hold the key to preserving long-term health and…
The world can be a hazardous place, with various dangers lurking around us such as bacteria, viruses, accidents, and injuries. Our skin acts as the…
Scientists have discovered the molecular basis for the ultrafast contraction of Spirostomum, a genus of millimeter-scale single-celled protists known for their incredibly rapid movement. Using…
Misfolded proteins pose a threat to cellular health, as they interfere with normal functions and contribute to age-associated degenerative conditions such as Alzheimer’s, Parkinson’s, and…
Scientists at UC San Diego have found a correlation between high levels of a gene product, commonly produced by various types of cancer, and a…
A research project carried out by the University of Bonn holds promise for the development of treatments for skin and gut disorders in the medium…
Neurons that form part of a memory circuit are among the first brain cells to show signs of neurodegeneration in Alzheimer’s disease. MIT researchers identified…
The Mathematics of Cell Boundary “Ruggedness” Researchers have uncovered both the mathematical and biological mechanism behind the rugged structures at cell boundaries found in tissues…
A recent study in mice has found that a history of obesity resulting from a high-fat diet can induce lasting changes in innate immunity that…
