A key protein involved in fat metabolism has been found to do more than scientists once thought. Instead of just releasing fat, it helps maintain healthy fat tissue and balance in the body. When it's missing or disrupted, the results can be ...

Researchers have identified a new potential weapon against Alzheimer's: blocking a protein called PTP1B. In mice, this approach boosted memory and helped brain immune cells clear harmful plaque buildup. Since PTP1B is also linked to diabetes and ...

A major review of 217 trials shows that aerobic exercise is the most effective option for managing knee osteoarthritis. Activities like walking, cycling, and swimming outperformed other exercise types in reducing pain and improving movement. While .. ...

For decades, psychologists have debated whether the human mind can be explained by one unified theory or must be broken into separate parts like memory and attention. A recent AI model called Centaur seemed to offer a breakthrough, claiming it could ...

Scientists have finally cracked one of the biggest mysteries in the senses: how smell is organized. By mapping millions of neurons in mice, researchers discovered that smell receptors in the nose aren't random at all--they're arranged in neat, ...

The body's "killer" T cells don't just attack--they strike with astonishing precision, forming a tiny, highly organized contact zone that lets them destroy dangerous cells without harming their neighbors. Now, scientists have captured this process in ...

A decades-old drug once used to treat sleeping sickness is now showing surprising promise against an ultra-rare and life-threatening genetic disorder called Bachmann-Bupp syndrome (BABS). Early patient treatments suggest the drug, DFMO, may ease ...

A troubling new study from MIT reveals that a common environmental contaminant, NDMA--found in polluted water, certain medications, and even processed foods--may pose a far greater cancer risk to children than adults. In experiments with mice, young ...

Scientists at MIT discovered that chaotic laser light can spontaneously form a highly focused beam instead of scattering--if the conditions are just right. This "pencil beam" enabled them to image the blood-brain barrier in 3D at speeds 25 times ...

Dreams are more structured than they seem, shaped by both personal traits and real-world experiences. Researchers found that the brain doesn't just replay daily life--it reshapes it into imaginative, sometimes surreal scenarios. People who mind ...
