Phys.org / Sourdough starters reveal a recipe for predicting microbial species survival

People have long said that "bread is life." Now, researchers at Tufts University are using the bubbling mixtures of flour and water known as sourdough starters to explore what shapes life at the microscopic level. Their findings, ...

Phys.org / Hubble uncovers the secret of blue straggler stars that defy aging

Some stars appear to defy time itself. Nestled within ancient star clusters, they shine bluer and brighter than their neighbors, looking far younger than their true age. Known as blue straggler stars, these stellar oddities ...
