Unexpected insights into the dynamic structure of mitochondria

As power plants and energy stores, mitochondria are essential components of almost all cells in plants, fungi and animals. Until now, it has been assumed that these functions underlie a static structure of mitochondrial membranes. ...

Researchers discover how cells clear misfolded proteins from tissues

Researchers in Japan have identified a new quality control system that allows cells to remove damaged and potentially toxic proteins from their surroundings. The study, which will be published February 18 in the Journal of ...

Atomic structures mapped in measles, mumps, flu and RSV

Northwestern University researchers have, for the first time, determined the 3-D atomic structure of a key complex in paramyxoviruses, a family of viruses that includes measles, mumps, human parainfluenza and respiratory ...

Reproductive genome from the laboratory

The field of synthetic biology does not only observe and describe processes of life but also mimics them. A key characteristic of life is the ability for replication, which means the maintenance of a chemical system. Scientists ...

Tiny, erratic protein motor movements revealed

The smallest proteins travel in our cells, completing deeply important tasks to keep our molecular mechanisms moving. They are responsible for transporting cargo, duplicating cells and more. Now, a research team based in ...

Leaking away essential resources actually helps cells grow

Experts have been unable to explain why cells, from bacteria to humans, leak essential chemicals necessary for growth into their environment. New mathematical models reveal that leaking metabolites—substances involved in ...

Cryo-electron microscopy opens a door to fight Epstein-Barr

The Epstein-Barr virus is one of the most widespread human viruses. Part of the herpesvirus family, it causes glandular fever (infectious mononucleosis), cancer and autoimmune diseases. At present, there is no treatment for ...

Transparent human organs allow 3-D maps at the cellular level

For the first time, researchers have managed to make intact human organs transparent. Using microscopic imaging, they revealed complex underlying structures of the transparent organs at the cellular level. The resulting organ ...

Biologists investigate the role of the largest animal brain cells

The brains of most fish and amphibian species contain two types of conspicuously large nerve cells. These are the largest cells found in any animal brain. They are called Mauthner cells and trigger lightning-fast escape responses ...
