Skin
In zootomy and dermatology, skin is an organ of the integumentary system composed of a layer of tissues that protect underlying muscles and organs. Skin has pigmentation, provided by melanocytes, which absorbs some of the potentially dangerous radiation in sunlight.

Oct. 25, 2025 Inside your body, an intricate communication network constantly monitors breathing, heart rate, digestion, and immune function — a hidden “sixth sense” called interoception. Now, Nobel laureate ...
Oct. 25, 2025 Scientists at The University of Texas at Austin have developed a revolutionary gene-editing method using bacterial retrons that can correct multiple disease-causing mutations at once. Unlike traditional tools limited to one or two mutations, this ...
Oct. 25, 2025 Reptiles don’t just pee, they crystallize their waste. Researchers found that snakes and other reptiles form tiny uric acid spheres, a water-saving evolutionary trick. This discovery could illuminate how to prevent gout and kidney stones in ...
Oct. 25, 2025 Scientists have identified mutations in the CPD gene as a key cause of a rare congenital hearing loss, revealing how disruptions in arginine and nitric oxide signaling damage sensory cells in the ...
Oct. 24, 2025 Researchers uncovered how lung cells decide whether to rebuild tissue or fight infection. This built-in “switch” may be the key to restoring the lungs’ natural repair ability. The discovery could lead to regenerative treatments for chronic ...
Oct. 24, 2025 ASU scientists found that people whose gut microbes make more methane extract more calories from fiber-rich foods. Methanogens help the microbiome turn fiber into energy by consuming hydrogen and producing methane. Using advanced metabolic chambers, ...
Oct. 24, 2025 A massive genetic study found that naturally lower cholesterol is linked to a dramatically reduced risk of dementia. The research simulated the effects of cholesterol-lowering drugs and showed up to an 80% lower risk for certain genetic profiles. ...
Oct. 24, 2025 Researchers have finally seen and measured the tiny alpha-synuclein oligomers that may ignite Parkinson’s disease. With the ultra-sensitive ASA-PD imaging method, they captured these clusters in brain tissue, finding larger and more numerous ...
Oct. 23, 2025 Cedars-Sinai researchers created “young” immune cells from human stem cells that reversed cognitive decline and Alzheimer’s symptoms in mice. The treated animals showed better memory and healthier brain structures. The cells seemed to protect ...
Oct. 23, 2025 McMaster researchers found that deep abdominal and liver fat can quietly damage arteries, even in people who appear fit. Their MRI-based study of over 33,000 adults shows these fats are closely ...
Oct. 23, 2025 MIT scientists have found that an amino acid called cysteine can help the gut heal itself. In mouse studies, a cysteine-rich diet activated immune cells that release a molecule speeding up tissue repair in the small intestine. This process helped ...
Oct. 22, 2025 Texas A&M researchers found that in an aggressive kidney cancer, RNA builds “droplet hubs” that activate tumor genes. By creating a molecular switch to dissolve these hubs, they stopped cancer growth in lab and mouse tests. The work reveals how ...
