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 skin, boosting collagen and skin renewal. People who ...
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. 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 against infections. This raises questions about ...
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 sponsored by Neurotech Pharmaceuticals and ...
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 use oxygen to make energy efficiently, cancer 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 other retinal ...
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 early indicator for Alzheimer's ...
Mar. 2, 2025 Why retinoic acid is effective in this setting but not against primary tumors, has been speculated about for nearly 50 years. Scientists resolved the mystery, showing the drug 'hijacks' a normal ...

Feb. 4, 2025 Researchers have conducted one of the largest eye studies in the world to reveal new insights into retinal thickness, highlighting its potential in the early detection of diseases like type 2 ...
Feb. 3, 2025 Maternal vitamin D levels in the first trimester were related to both prenatal growth and pregnancy outcomes, according to a new study. Low vitamin D levels during the first trimester of pregnancy ...
Oct. 16, 2024 Researchers have identified new drug targets for therapies that could benefit patients with different forms of retinitis pigmentosa and other ...
Oct. 3, 2024 Human stem cell transplants successfully repaired macular holes in a monkey model, researchers report. After transplantation, the macular holes were closed by continuous filling of the space with ...
May 18, 2024 Researchers have discovered the virus that causes COVID-19 can breach the protective blood-retinal-barrier with potential long-term consequences in ...
May 17, 2024 In what they believe is a solution to a 30-year biological mystery, neuroscientists say they have used genetically engineered mice to address how one mutation in the gene for the light-sensing ...
Mar. 25, 2024 Scientists have created a biocompatible artificial vitreous body derived from algae-derived ...
Mar. 10, 2024 Retinoic acid, the active state of Vitamin A, appears to regulate how stem cells enter and exit a transient state central to their role in wound ...
Feb. 23, 2024 Researchers have discovered profound similarities and surprising differences between humans and insects in the production of the critical light-absorbing molecule of the retina, 11-cis-retinal, also ...

Dec. 13, 2023 In a comparative analysis across vertebrates of the many cell types in the retina -- mice alone have 130 types -- researchers concluded that most cell types have an ancient evolutionary history. ...
Aug. 18, 2023 According to new research, T cells have a nuclear receptor doing something very odd—but very important—to help them fight pathogens and destroy cancer cells. This receptor, called retinoic acid ...
Apr. 3, 2023 For more than 50 years, it has been suspected that fat cells constantly remodel the lipids they store. Researchers have now demonstrated this process directly for the first time using culture cells. ...
