Swimming
Swimming is a technique that humans, and other animals, use to move through water using only movements of the body, for exercise, fun and competition. There are health benefits of swimming, but also risks. Swimming is an excellent form of exercise. Because the density of the human body is approximately similar to that of water, the body is supported by the water and less stress is therefore placed on joints and bones. Therefore, swimming is frequently used as an exercise in rehabilitation after injuries or for those with disabilities.

Oct. 16, 2025 — Scientists have found a way to transform hard-to-treat tumors into targets for the immune system. Using two protein stimulators, they activated strong T-cell and B-cell responses and built immune structures inside tumors that improved survival and ...
Oct. 16, 2025 — Long before humans built cities or wrote words, our ancestors may have faced a hidden threat that shaped who we became. Scientists studying ancient teeth found that early humans, great apes, and even Neanderthals were exposed to lead millions of ...
Oct. 16, 2025 — Johns Hopkins scientists uncovered microscopic “nanotube” channels that neurons use to transfer toxic molecules. While this process clears waste, it can also spread harmful proteins like amyloid-beta. Alzheimer’s-model mice showed more ...
Oct. 15, 2025 — Scientists discovered that lean pork builds muscle more effectively post-workout than high-fat pork, even with identical protein levels. Using advanced tracking techniques, they found that fat content blunted the body’s muscle-building response. ...
Oct. 15, 2025 — Korean researchers found that low-dose radiation therapy eased knee pain and improved movement in people with mild to moderate osteoarthritis. The treatment, far weaker than cancer radiation, showed real benefits beyond placebo. With no side effects ...
Oct. 15, 2025 — Scientists discovered that specific nutrients in nematodes' diets activate stress defenses that keep their cells healthier over time. These RNAs prevent toxic protein buildup, promoting longevity and vitality. The worms fed with balanced diets lived ...
Oct. 15, 2025 — A new human liver organoid microarray developed by Cincinnati Children’s and Roche recreates immune-driven liver injury in the lab. Built from patient-derived stem cells and immune cells, it accurately models how genetics influence drug reactions. ...
Oct. 14, 2025 — Endurance exercise may train the immune system as much as the muscles. Older adults with decades of running or cycling had immune cells that functioned better and aged more slowly. Their inflammation levels were lower and their cells resisted ...
Oct. 14, 2025 — Researchers have synthesized enhanced vitamin K analogues that outperform natural vitamin K in promoting neuron growth. The new compounds, which combine vitamin K with retinoic acid, activate the mGluR1 receptor to drive neurogenesis. They also ...
Oct. 14, 2025 — Researchers at USC have created the first method to noninvasively measure microscopic blood vessel pulses in the human brain. Using advanced 7T MRI, they found these tiny pulsations grow stronger with age and vascular risk, disrupting the brain’s ...
Oct. 14, 2025 — Scientists at UC Irvine have found a way to potentially reverse age-related vision loss by targeting the ELOVL2 “aging gene” and restoring vital fatty acids in the retina. Their experiments in mice show that supplementing with specific ...
Oct. 14, 2025 — Groundbreaking Harvard research is exposing hidden energy failures inside brain cells that may drive major psychiatric conditions. By studying reprogrammed neurons, scientists are revealing how cellular metabolism shapes mood, thought, and ...
