Extra virgin olive oil might help protect your brain by working through your gut. A two-year study found that people who consumed it had better cognitive performance and more diverse gut bacteria than those using refined olive oil. Researchers even . ...

Sitting all day might not be as damaging as once feared--if you're willing to move more. A massive study tracking over 72,000 people found that simply increasing daily steps can significantly reduce the risk of death and heart disease, even for those ...

Engineers at Northwestern University have taken a striking leap toward merging machines with the human brain by printing artificial neurons that can actually communicate with real ones. These flexible, low-cost devices generate lifelike electrical .. ...

A surprising new study suggests that eating a very healthy diet--packed with fruits, vegetables, and whole grains--might be linked to a higher risk of lung cancer in younger non-smokers. Researchers found that patients under 50 diagnosed with lung .. ...

Scientists have uncovered a surprising twist in how bacteria share genes--including those that spread antibiotic resistance. Tiny virus-like particles called gene transfer agents (GTAs), once ancient viral invaders, have been repurposed by bacteria . ...

Sparkling water is often seen as a simple, healthy drink--but could it also help with weight loss? New research suggests it may slightly boost how the body processes blood sugar and energy. However, the effect is very small, meaning it's no ...

A hormone called FGF21 can reverse obesity in mice by activating a newly identified brain circuit tied to metabolism. Surprisingly, it works in the hindbrain--the same region targeted by GLP-1 drugs like Ozempic and Wegovy--but through a completely . ...

Researchers have found a way to make cancer-killing immune cells more powerful and precise. By adding specific signaling components, they boosted the cells' readiness to attack tumors. Surprisingly, briefly suppressing the cells with a drug before .. ...

Scientists have discovered that a protein linked to cell death is secretly driving the aging of blood stem cells in a completely different way. Instead of killing the cells, it damages their mitochondria, sapping their energy and weakening the immune ...

A rogue set of "zombie" immune cells may be driving aging and fatty liver disease by flooding tissues with inflammation. Researchers found these cells accumulate with age and high cholesterol--and can make up most of the liver's immune cells in older ...
