Scientists have now developed a drug that shuts down this pathway, dramatically boosting immune responses and slowing cancer growth in preclinical studies.

The hair-thin patch replaces damaged retinal cells responsible for sharp, central vision. Earlier studies showed the implant was safe and helped some patients see better. Researchers now hope it can deliver meaningful, lasting improvements in eyesight.

Scientists discovered that vitamin C from food travels through the bloodstream into every layer of the skin, boosting collagen and skin renewal. People who ate two vitamin C–packed kiwifruit daily showed thicker, healthier skin. The findings suggest glowing skin really does start from within.

The new compounds, which combine vitamin K with retinoic acid, activate the mGluR1 receptor to drive neurogenesis. They also efficiently cross the blood-brain barrier and show stability in vivo. This discovery could pave the way for regenerative treatments for Alzheimer’s and related diseases.

But now, a new study sponsored by Neurotech Pharmaceuticals and spearheaded by investigators at Scripps Research and the National Institutes of Health offers compelling evidence that vision loss can be slowed with a neuroprotective surgical implant.

While healthy cells use oxygen to make energy efficiently, cancer cells often rely on a backup method. This ginger-derived molecule doesn t attack that method directly it shuts down the cells' fat-making machinery instead, which surprisingly causes the cells to ramp up their backup system even more. The finding opens new doors in the fight against cancer, showing how natural substances might help target cancer s hidden energy tricks.

They found significant associations between the thinning of different retinal layers and increased risk of developing eye, neuropsychiatric, cardiac, metabolic, and pulmonary diseases and identified genes that are associated with retinal layer thickness. Their hope is one day patients can be provided more personalized risk assessments and referred to specialists for preventive and treatment plans for eye and other diseases.

The findings increase understanding of color blindness, age-related vision loss, and other diseases linked to photoreceptor cells. They also demonstrate how genes instruct the human retina to make specific color-sensing cells, a process scientists thought was controlled by thyroid hormones.

Their remarkable conservation across species suggests that the retina of the last common ancestor of all mammals, which roamed the earth some 200 million year ago, must have had a complexity rivaling the retina of modern mammals.

This receptor, called retinoic acid receptor alpha, is known to control gene expression programs in the nucleus, but it also now appears to operate outside the cell nucleus to coordinate the early events triggered at the cell surface that lead to T cell activation.

Researchers have now demonstrated this process directly for the first time using culture cells. Among other things, the study shows that the cells quickly eliminate harmful fatty acids. They refine others into molecules that can be used more effectively. In the long term, this turns the components of palm fat into the building blocks of high-quality olive oil, for example.

More than 50 percent of people in the U.S. over age 60 are affected by diseases that impact the retina's function in ways that reduce eyesight and can progress to blindness if not treated.

Additionally, they showed in mouse models that the death of retinal ganglion cells can be prevented by using medications to inhibit a molecule called Galectin-3, which is regulated by the APOE gene. These findings taken together emphasize the critical role of APOE in glaucoma and suggest that Galectin-3 inhibitors hold promise as a glaucoma treatment.
