Study: Depression in fathers and children linked

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.

Exercise may sharpen the mind by repairing the brain's protective shield. Researchers found that physical activity prompts the liver to release an enzyme that removes a harmful protein, causing the blood-brain barrier to become leaky with age.

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.

Researchers have found a reliable way to grow helper T cells from stem cells, solving a major challenge in immune-based cancer therapy. Helper T cells act as the immune system's coordinators, helping other immune cells fight longer and harder.

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.

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 massive international brain study has revealed that memory decline with age isn't driven by a single brain region or gene, but by widespread structural changes across the brain that build up over time.

Researchers have discovered a way to help aging intestines heal themselves using CAR T-cell therapy. By targeting senescent cells that build up over time, the treatment boosted gut regeneration, reduced inflammation, and improved nutrient absorption in mice.

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.
