When an outbreak strikes, humans try to avoid germs. (Remember wiping off groceries at the start of the pandemic?) What about ... monkeys?

Nigeria this week recorded its first case of Ebola in the current outbreak, which has spread from the epicenter in Congo to several other African countries.

Researchers have uncovered a surprising reason dental implant infections often resist antibiotics: the implants themselves can contribute to the problem. Bacteria corrode titanium implants, releasing microscopic particles that hijack immune cells, trigger destructive inflammation, and accelerate jawbone loss.

A newly FDA-cleared PTSD treatment uses personalized brain mapping and magnetic stimulation to target abnormal brain activity, with a clinical trial reporting a 52% reduction in symptoms and 68% remission. Researchers believe the technology could transform PTSD care and pave the way for more precise treatments for other mental health conditions.

A seven-year study found that people with Parkinson’s disease who were more physically active experienced slower declines in memory, thinking, and movement abilities. Those exercising more than eight hours per week showed almost no average cognitive decline, suggesting that staying active may offer important benefits as the disease progresses.

It's a day to think about all the upcoming appointments and commitments you're dreading — and then decline some of them. Writer Caroline Sylge shares a suggested schedule for the day.

Cambridge researchers have created a groundbreaking $10 optical sensor that delivers the precision of laboratory equipment in a device small enough for wearable technology. It identified foods, plastics, and medicines with 100% accuracy in tests and demonstrated the ability to monitor blood glucose, alcohol, and other health markers without invasive procedures.

Researchers have uncovered a hidden immune defense capable of attacking small cell lung cancer, an extremely aggressive disease that often escapes conventional treatments. The specialized immune cells can recognize and destroy cancer cells even when tumors have disguised themselves from the immune system.

A surprising two-year clinical trial found that fish oil supplements successfully delivered omega-3s to the brain but failed to improve memory or protect against Alzheimer's-related brain shrinkage. Researchers suspect that getting these nutrients through a healthy diet may offer benefits that supplements alone cannot provide.

Scientists have captured virus-like particles assembling themselves step by step, revealing how a surprisingly simple process of trial and error produces complex structures with remarkable precision. The discovery uncovers a crucial molecular turning point that speeds up assembly and could lead to new ways to disrupt viruses and develop vaccines.
