The study suggests a previously unobserved relationship between body temperature and REM sleep, with REM sleep appearing to act like a ‘thermostatically controlled brain heater.’

Researchers used data from large studies that contained laboratory measurements of two-drug combinations of 12 anti-tuberculosis drugs. Using mathematical models, the team discovered a set of rules that drug pairs need to satisfy to be potentially good…

High levels of mucosal antibodies in the airways reduce the risk of being infected by omicron, but many do not receive detectable antibodies in the airways despite three doses of the SARS-CoV-2 vaccine, according to a new study.

Boxers and mixed martial arts (MMA) fighters may see some recovery in their thinking and memory skills as well as brain structure after they stop fighting, according to a new study.

A combination of seven healthy lifestyle habits including sleeping seven to nine hours daily, exercising regularly and having frequent social contact was associated with a lower risk of dementia in people with type 2 diabetes, according to a study publ…

Chemists have discovered a new oxidation state of rhodium. This chemical element is one of the most catalytically important platinum-group metals and is used, for example, in catalytic converters for automobiles. Rhodium is actually already well studied.

Nearly nine in ten cases of sudden cardiac death (SCD) due to hypertrophic cardiomyopathy (HCM) in young people are preceded by symptoms, ECG abnormalities or a positive family history, according to a new study. Those findings suggest that expanding ca…

Tiny crystals in ancient animal dung serve as key evidence in a new analysis suggesting the possibility that hunter-gatherers at Abu Hureyra, Syria, may have tended small numbers of animals just outside their dwellings between 12,800 and 12,300 years a…

Researchers demonstrate a clear connection between personality in wandering albatross (Diomedea exulans) and the likelihood of divorce. Though the link between personality and relationship outcomes in humans is well-established, this is the first study…

In a new study, researchers across North America have modeled how antimicrobial use impacts the emergence of antimicrobial resistance in Escherichia coli isolated from Canadian turkey flocks.

A three-year study in northeastern Illinois and northwestern Indiana found that — even at small scales — emergent wetlands or ponds support many wetland bird species. The study also found that, at least in the years surveyed, the level of urbanizatio…

A team develops a nanoreactor combining magnetic material and plasmonic catalysts. Remote control of step-by-step catalytic reactions of precursor led to cinnamaldehyde product with 95% yield.

Various approaches for treating lymph node metastasis exist. But now, a research team has combined two forms of therapy to create a superior treatment method than conventional chemotherapy.

The memory system alternates between periods of learning and remembering. These two functions are controlled by different neural circuits. Using an animal model, scientists recently identified a neural signal in the hippocampus, a brain region essentia…
