The connection between how long an organism lives and how it uses energy has been studied for years. However, the specific ways that energy processes control lifespan are still a mystery. Daphnids are tiny water creatures. Some daphnids, like Daphnia sinensis, are always on the move. They swim around a lot. Others, like Simocephalus vetulus, are more laid-back. ...

Endurance races push horses to their limits. To understand how these animals cope, scientists looked at how their bodies change during an 80 km race. They focused on proteins in the horses' blood, which can show what's happening inside the body. The scientists took blood samples from 13 horses before and after the race. They used a special method to measure the amou...

Scientists have found something called a Universal Receptive System. It's like a control system for cells, both good and bad ones. This system uses special receptors called TezRs, made from DNA or RNA. They're on the cell's surface, helping cells respond to their environment. A recent study focused on these TezRs in a bad bacteria, Staphylococcus aureus. They tweaked...
