Repeated vaccinations help prevent influenza in older adults

A popular fitness trend among young people may be quietly undermining their sleep. A new study led by researchers at the University of Toronto has found that teenagers and young adults who use pre-workout supplements are significantly more likely to experience extremely short sleep durations.

Worrying about getting older especially fearing future health problems may actually speed up aging at the cellular level, according to new research from NYU.

Human evolution has long been tied to growing brain size, and new research suggests prenatal hormones may have played a surprising role. By studying the relative lengths of the index and ring fingers, a marker of prenatal exposure to oestrogen and testosterone, researchers found that higher prenatal oestrogen exposure was associated with larger head size in newborn boys.

New research suggests that consistent aerobic exercise can help keep your brain biologically younger. Adults who exercised regularly for a year showed brains that appeared nearly a year younger than those who didn't change their habits.

A long-running Swedish study has followed adults for nearly five decades, uncovering when physical decline truly begins. Fitness and strength start slipping around age 35, then worsen gradually with age.

A high-fat diet does more than overload the liver with fat. New research from MIT shows that prolonged exposure to fatty foods can push liver cells into a survival mode that quietly raises the risk of cancer.

Alzheimer's has long been considered irreversible, but new research challenges that assumption. Scientists discovered that severe drops in the brain's energy supply help drive the disease, and restoring that balance can reverse damage, even in advanced cases.

A research team has found that specific immune cells can connect with muscle fibres in a lightning-fast, neuron-like way to promote healing.

Researchers have, for the first time, estimated how quickly E. coli bacteria can spread between people and one strain moves as fast as swine flu.

Scientists discovered that tiny messengers released by fat tissue, called extracellular vesicles, can carry harmful signals that accelerate the buildup of amyloid-b plaques in the brain.
