New nutrient-rich protein powders to boost the health of active older people are being developed with the help of an artificial stomach at Aberystwyth University.

A research group led by a researcher at the Earth-Life Science Institute (ELSI) at Institute of Science Tokyo has uncovered how “latecomer killing,” a toxin-based survival strategy found in distantly related yeast species, could persist for hundreds of millions of years. Their population-dynamics theory shows that alternating nutrient-rich and starvation periods can stabilise this strategy by preventing takeover by toxin-resistant evolutionary "cheaters." The findings offer new insights into how fluctuating environments shape microbial evolution.

Findings from a new study comparing the effects of different beverages on mouth acidity suggest that unsweetened sparkling water may be better for your teeth than sugar-sweetened soda.
