Artificial intelligence model detects asymptomatic Covid-19 infections through cellphone-recorded coughs

A study by scientists at UNC Lineberger Comprehensive Cancer Center and colleagues showed that mice exposed to potentially lethal levels of total body radiation were protected from radiation damage if they had specific types of bacteria in their gut. They demonstrated that the bacteria mitigated radiation exposure and enhanced the recovery of blood cell production as well as repair of the gastroin

Beetroot peptide as potential drug candidate for treating diseases
In a recent study, a research group led by Christian Gruber at MedUni Vienna's Institute of Pharmacology isolated a peptide (small protein molecule) from beetroot. The peptide is able to inhibit a particular enzyme that is responsible for the breakdown of messenger molecules in the body. Due to its particularly stable molecular structure and pharmacological properties, the beetroot peptide may be
