Scientists in the UK think they may have found a cheap, low-tech way to help fight age-related loss of vision. In a small clinical trial, people over 40 who were told to stare into a deep red light for three minutes a day had noticeable improvements to their sight. They reported being able to see better in the dark and to better distinguish colors.
UK officials have approved two women for mitochondrial replacement therapy, the fertilization procedure that results in a baby technically parented by three people, the Guardian reports. The procedure, which still isn’t approved in the US, was legalized in the UK in 2015 and the Newcastle Fertility Centre, where the two women will be treated, was granted a license to perform the procedure last March. While it’s not the first time a procedure like this has been done, it is the first time it will happen in the UK.
