An artist’s rendering incorporates the images of the Müller glia-derived rod photoreceptors. These photoreceptors were structurally no different from real photoreceptors and they became integrated within the circuitry of the visual pathway, from the retina to the brain. Credit: Bo Chen, Ph.D.

New technique generates rod photoreceptors that integrate into the retina and brain. Researchers funded by the National Eye Institute (NEI) have reversed congenital blindness in mice by changing supportive cells in the retina called Müller glia into rod photoreceptors. The findings advance efforts toward regenerative therapies for blinding diseases such as age-related macular degeneration and retinitis pigmentosa.

“This is the first report of scientists reprogramming Müller glia to become functional...

Researchers show holonomic quantum gates under zero-magnetic field at room temperature, which will enable the realization of fast and fault-tolerant universal quantum computers. A quantum computer is a powerful machine with the potential to solve complex problems much faster than today’s conventional computer can. Researchers are currently working on the next step in quantum computing: building a universal quantum computer.

The paper, published in the journal Nature Communications, reports experimental demonstration of non-adiabatic and non-abelian holonomic quantum gates over a ...

Three generations. Women whose mothers lived into their ninth decade enjoyed 25 percent increased likelihood of also doing so without suffering from serious or chronic illness, including heart disease, stroke, diabetes, cancer, hip fractures or other debilitating disabilities.

Results show a 25% increased likelihood of living longer and healthier if mom lived to age 90 and a 38% increase if both parents did. The study, published in Age and Ageing, found women whose mothers lived into their ninth decade enjoyed 25% increased likelihood of also doing so without suffering from serious or chronic illness, including heart disease, stroke, diabetes, cancer, hip fractures or other debilitating disabilities.

“Achieving healthy aging has become a critical public he...

Computer simulation of a region of the universe wherein a low-density “void” (dark blue region at top center) is surrounded by denser structures containing numerous galaxies (orange/white). The research done by Becker and his team suggests that early in cosmic history, these void regions would have been the murkiest places in the universe even though they contained the least amount of dark matter and gas.

A team of astronomers led by George Becker at the University of California, Riverside, has made a surprising discovery: 12.5 billion years ago, the most opaque place in the universe contained relatively little matter. It has long been known that the universe is filled with a web-like network of dark matter and gas...
