Aug. 28, 2026 Scientists have created light-activated drugs that helped blind mice perceive light again and restored visually guided behavior without gene therapy, implants, or specialized lighting. Even more intriguingly, two of the most promising compounds ...
Aug. 13, 2026 A large study of more than 5,500 adults over 50 found a striking combination of risk factors: abdominal obesity paired with vitamin D deficiency was linked to a 123% higher risk of death over six ...
Aug. 7, 2026 Linus Pauling was widely mocked for claiming that vitamin C could fight cancer, especially after trials using vitamin C pills showed no benefit. Researchers now know that intravenous vitamin C reaches vastly higher concentrations and can behave more ...
June 26, 2026 The battle between butter and margarine comes down to chemistry. Butter’s naturally occurring fats create rich flavors, golden browning, and flaky baked goods, while margarine’s modified plant oils offer consistency and a longer shelf life. ...
June 25, 2026 Vitamin B12 is needed in microscopic amounts, but a shortage can have major effects on health and energy. The vitamin was first linked to a lifesaving liver treatment for pernicious anemia nearly 100 years ago. Today, researchers are finding that ...
June 6, 2026 Supplements are often marketed as shortcuts to better health, but for many older adults, the real issue is whether they have a specific deficiency. Vitamins like B12 and D can play an important role when levels are low, while protein may be one of ...
May 30, 2026 A new study suggests melatonin supplements may help night shift workers boost their body's DNA repair processes, potentially offsetting some of the damage linked to working overnight. The findings ...
May 27, 2026 Scientists in Japan have created powerful new vitamin K-based compounds that may help the brain regenerate lost neurons — a breakthrough that could one day change how diseases like Alzheimer’s and Parkinson’s are treated. By combining vitamin ...
May 23, 2026 A surprising study suggests vitamin D2 supplements may reduce the body’s levels of vitamin D3 — the more effective form of vitamin D. Researchers found D3 not only boosts vitamin D status more ...
May 19, 2026 Low vitamin D levels could be quietly making breast cancer surgery recovery far more painful. In a new study, patients deficient in vitamin D were three times more likely to experience moderate to severe pain after mastectomy surgery and ended up ...
Jan. 16, 2026 A vitamin A byproduct has been found to quietly disarm the immune system, allowing tumors to evade attack and weakening cancer vaccines. Scientists have now developed a drug that shuts down this pathway, dramatically boosting immune responses and ...
Jan. 9, 2026 Scientists at USC are launching a new trial to test a tiny stem cell implant that could restore vision in people with advanced dry macular degeneration. The hair-thin patch replaces damaged retinal cells responsible for sharp, central vision. ...

Dec. 26, 2025 Vitamin C doesn’t just belong in skincare products—it works even better when you eat it. Scientists discovered that vitamin C from food travels through the bloodstream into every layer of the ...
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 ...
Oct. 4, 2025 Scientists discovered that vitamin D2 supplements can lower levels of vitamin D3, the form the body uses most effectively. Unlike D2, vitamin D3 enhances the immune system’s first line of defense ...
Aug. 29, 2025 For people with macular telangiectasia type 2 (MacTel), an orphan retinal disorder that gradually destroys central vision, there have long been no approved treatment options. But now, a new study ...
June 10, 2025 Scientists in Japan have discovered that a natural compound found in a type of ginger called kencur can throw cancer cells into disarray by disrupting how they generate energy. While healthy cells ...
May 26, 2025 Scientists have developed new tools to improve gene therapy in advanced stages of inherited retinal diseases (IRDs) such as retinitis pigmentosa and Leber congenital ...
Apr. 16, 2025 A team of researchers has identified a promising new approach that may one day help to restore vision in people affected by macular degeneration and ...
Apr. 2, 2025 Researchers have successfully developed a novel drug to restore vision. The treatment method restores vision through retinal nerve ...
Mar. 21, 2025 Researchers have developed eye drops that extend vision in animal models of a group of inherited diseases that lead to progressive vision loss in humans, known as retinitis ...
Mar. 3, 2025 A team of scientists has identified that an eye condition affecting the retina, the light-sensing tissue in the back of the eye, may serve as an ...
