Negative thoughts of new mothers may affect interaction with their babies

A new study suggests that eating more fat rather than less could help the body gain greater benefits from exercise when blood sugar levels are high, offering an unexpected perspective on how diet and physical activity work together to support metabolic health.

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.

Living at high altitude appears to protect against diabetes, and scientists have finally discovered the reason. When oxygen levels drop, red blood cells switch into a new metabolic mode and absorb large amounts of glucose from the blood.

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.

The scientists have discovered that the adolescent brain does more than prune old connections. During the teen years, it actively builds dense new clusters of synapses in specific parts of neurons.

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.

Scientists have discovered new anti-ageing compounds produced by a little-studied blood bacterium, opening up promising avenues for future skin-rejuvenation therapies.
