Researchers have found that the time of day can make a big difference in how badly noise hurts your hearing. They looked at cells in the inner ear and found that immune cells called macrophages play a big role in this. When the ear is exposed to loud noises, these macrophages get more active, especially at night. This leads to more inflammation and damage. The study...

The body's defense system is a complex network. It includes tiny soldiers called macrophages. These cells are always on the lookout for trouble. They can spot danger signals from invaders like bacteria or even tiny bits of metal. Two key players in this defense team are NLRP3 and AIM2. They are like alarm systems that sound the alert when trouble is detected. Macrop...
