Regular exercise does more than strengthen the heart. New research reveals that it actually reshapes the nerves controlling how the heart functions, and the changes are surprisingly different on the left and right sides of the body.

A powerful new AI system could help doctors detect pancreatic cancer years before it becomes visible on conventional scans. The technology, called REDMOD, identified hidden warning signs an average of 475 days before diagnosis and was nearly twice as sensitive as experienced radiologists. By spotting cancer-related changes at their earliest stages, it could dramatically improve the chances of successful treatment for one of the deadliest forms of cancer.

A simple liquid painted onto teeth in seconds can stop cavities without drilling, injections, or anesthesia, according to a major clinical trial involving young children. The inexpensive treatment could spare thousands of children painful dental procedures and surgery while paving the way for broader FDA-approved use.

Scientists have uncovered a surprising new clue to why the Mediterranean diet is so good for the heart, brain, and healthy aging. Researchers at USC found that older adults who closely followed the diet had higher levels of two tiny proteins, humanin and SHMOOSE, produced by the mitochondria, the energy-producing structures inside cells. These proteins have been linked to protection against heart disease, Alzheimer's disease, and age-related damage.

Scientists discovered that the thick, sticky fluid surrounding glioblastoma tumors can make brain cancer cells smaller, more flexible, and better at invading surrounding tissue. Even more troubling, some of these changes persist after the cells leave the thick fluid, revealing a previously overlooked mechanism that could help this deadly cancer spread.

A tiny region deep within the brain has surprised scientists by revealing a remarkably sophisticated communication system. Previously thought to broadcast the same chemical signal throughout the brain, this region actually sends targeted messages that help control learning, attention, and behavior, according to new research in mice.

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.
