Researchers have demonstrated the low environmental footprint of water fluoridation compared to other preventive measures for tooth decay. Research findings also strengthen the case internationally for water fluoridation programs to reduce dental decay…

The amount of SARS-CoV-2 antigen measured in the blood of patients hospitalized with COVID-19 is associated with illness severity and other clinical outcomes, according to a new study.

Research sheds new light on how plants, however rarely, experience mutations in their mitochondrial genomes. Unlike humans, plants are able to quickly fix these mutations, and more importantly, not pass them on to their progeny.

Approximately 13.5 million years ago, north-west Queensland was home to an unusual and particularly tiny species of crocodile and now scientists are unlocking its secrets.

A study more than 30 years in the making finds reintroducing bison would double plant biodiversity in a tallgrass prairie.

A new preclinical model for thymic cancer has revealed insights into how a common mutation found in thymic epithelial tumors sparks their formation. The model may help speed the development of targeted therapies for cancer of the thymus, a gland that m…

Physicists have proven — numerically and experimentally — that turbulence in fluid flows can be understood and quantified with the help of a small set of special solutions that can be precomputed for a particular geometry, once and for all. The findi…

A study of mice found that dietary sugar alters the gut microbiome, setting off a chain of events that leads to metabolic disease, pre-diabetes, and weight gain. The findings suggest that diet matters, but an optimal microbiome is equally important for…

Male bottlenose dolphins form the largest known multi-level alliance network outside humans, researchers have shown. These cooperative relationships between groups increase male access to a contested resource.

Amoebae receive surprising support in defense against viruses: The bacteria they are infected with prevent them from being destroyed by giant viruses. Microbiologists have investigated how a virus infection proceeds when the amoebae are simultaneously …
