Totally blind mice have had their sight restored by injections of light-sensing cells into the eye, UK researchers report.
The team in Oxford said their studies closely resemble the treatments that would be needed in people with degenerative eye disease. Similar results have already been achieved with night-blind mice.

Immune system 'booster' may hit cancer
Vast numbers of cells that can attack cancer and HIV have been grown in the lab, and could potentially be used to fight disease.
The cells naturally occur in small numbers, but it is hoped injecting huge quantities back into a patient could turbo-charge the immune system. The Japanese research is published in the journal Cell Stem Cell.
Experts said the results had exciting potential, but any therapy would need to be shown to be safe.
Study Suggests Lower Mortality Risk for People Deemed to Be Overweight
A century ago, Elsie Scheel was the perfect woman. So said a 1912 article in The New York Times about how Miss Scheel, 24, was chosen by the “medical examiner of the 400 ‘co-eds’ ” at Cornell University as a woman “whose very presence bespeaks perfect health.”
Miss Scheel, however, was hardly model-thin. At 5-foot-7 and 171 pounds, she would, by today’s medical standards, be clearly overweight. (Her body mass index was 27; 25 to 29.9 is overweight.)
Graphic anti-smoking ad launched in England
A series of hard-hitting government adverts featuring people smoking cigarettes with a tumour growing from the end is being launched in England.
The ads will tell smokers that just 15 cigarettes can cause a mutation that leads to cancerous tumours in what marks a return to shock campaigning.
It is eight years since government's "fatty cigarette" anti-smoking adverts appeared.
This £2.7m ad campaign will appear on TV, online and posters until February.
Medical field works to reduce number of surgical mistakes
Surgical errors have attracted widespread attention over the past several years, leading to new laws and policies. In 2007, California started requiring hospitals to report certain errors and fining them if the mistakes killed or seriously injured patients.
The next year, Medicare stopped paying hospitals for the costs associated with certain errors. In 2011, Medicaid announced that it also would stop paying to fix certain preventable mistakes.
Big Pharma cashes in on HGH abuse
A federal crackdown on illicit foreign supplies of human growth hormone has failed to stop rampant misuse, and instead has driven record sales of the drug by some of the world's biggest pharmaceutical companies, an Associated Press investigation shows.
The crackdown, which began in 2006, reduced the illegal flow of unregulated supplies from China, India and Mexico.
Philippines passes contraception reforms
The Philippines Congress approved its Reproductive Health Bill, offering government-provided contraception and sex education classes, after heated debate.
The bill, known as the RH Bill, passed the Senate 13-8 and the House of Representatives 133-79 Sunday night. A reconciliation committee will work out differences in the House and Senate versions before the legislation goes to President Benigno Aquino, who is expected to sign it before Christmas, The Philippine Star reported Monday.
