A robotic microswarm may one day automate the routine of rinsing, brushing, and flossing teeth. A multidisciplinary team developed the technology, which employs a magnetic field to direct the iron oxide nanoparticle-based microrobots into antimicrobial bristle- and floss-shaped arrays.

A newly discovered star only takes four years to travel around the black hole at the center of our galaxy.

Researchers found that in mice how much they ate and when altered the nature of their gut microbiome: too much food too frequently resulted in poorer microbial and metabolic health.

Researchers definitively linked the function of a specific domain of proteins important in plant-microbe biology to a cancer trigger in humans, knowledge that had eluded scientists for decades.

A study has identified a molecule -- the purine inosine -- that boosts fat burning in brown adipocytes. The mechanism was discovered in mice, but probably exists in humans as well: If a transporter for inosine is less active, the mice remain significantly leaner despite a high-fat diet.

Scientist reveal a large, all-season ozone hole in the lower stratosphere over the tropics comparable in depth to that of the well-known springtime Antarctic hole, but roughly seven times greater in area. The observed data agree well with the cosmic-ray-driven electron reaction (CRE) model and strongly indicate the identical physical mechanism working for both Antarctic and tropical ozone holes.

A new vaccine candidate, named mosaic-8, containing pieces of eight different SARS-like betacoronaviruses provides broad protection against other related coronaviruses.

New genetic research from remote islands in the Pacific offers fresh insights into the ancestry and culture of the world's earliest seafarers, including family structure, social customs, and the ancestral populations of the people living there today.
