An unorthodox symbiotic theory about the origin of eukaryotes’ defining characteristic may soon be put to the test.
In the fight against viruses and other pathogens, scientists are looking beyond genes and proteins to the complex sugars, or glycans, on cell surfaces.
To combat resistant bacteria and refill the trickling antibiotic pipeline, scientists are getting help from deep learning networks.
The glial cells of the nervous system have been eclipsed in importance by neurons for decades. But glia are turning out to be central to many neurological functions, including pain perception.
To scientists’ surprise, blended mixtures of cytoplasm can reorganize themselves into cell-like compartments with working structural components.
Researchers explored the zone between life and death, charted the mind’s system for arranging ideas and memories and learned how life’s complexity emerged.
Taste and smell receptors in unexpected organs monitor the state of the body’s natural microbial health and raise an alarm over invading parasites.
The 2019 Nobel Prize in Physiology or Medicine honored William Kaelin Jr., Peter Ratcliffe and Gregg Semenza for their work on elucidating how cells adjust to low oxygen levels.
Cells in symbiotic partnership, sometimes nested one within the other and functioning like organelles, can borrow from their host’s genes to complete their own metabolic pathways.
