Microbial murder mystery solved

Immune cells called "killer cells" target bacteria invading the body's cells, but how do they do this so effectively? Bacteria can quickly evolve resistance against antibiotics, yet it seems they have not so readily been ...

Paradoxes in microbial economies

Microbes can produce many of the metabolic resources they need to survive. But because they have permeable cell walls, those resources can leak out into the surrounding environment. Since microbes often live in communities ...

A little stress is good for cellular health and longevity

Northwestern University molecular bioscientists have discovered that a little stress can be good for cellular health. The findings will help researchers better understand the molecular mechanisms that drive aging and risk ...

Researchers discover new pathway for handling stress

Balance is key to many physiological functions and it is especially true in the production and regulation of proteins. A balance of proteins in cells helps maintain health, but an unhealthy clumping can lead to a variety ...

A force-driven mechanism for establishing cell polarity

A team of researchers from the Mechanobiology Institute, Singapore (MBI) at the National University of Singapore, along with colleagues from Temasek Life Sciences Laboratory and A*STAR's Institute of Molecular and Cell Biology ...

How chromosomes 'cheat' for the chance to get into an egg

Each of your cells contains two copies of 23 chromosomes, one inherited from your father and one from your mother. Theoretically, when you create a gamete—a sperm or an egg—each copy has a 50-50 shot at being passed on. ...
