Google has released a JPEG encoder called ‘Guetzli’ that promises to shrink an image's file size by up to 35% without losing any perceivable picture quality.
Stem cells grow skin without grafts
Severe burns have traditionally been treated with the use of skin grafts – a process where healthy skin is removed from an unobtrusive area of the victims own body (such as their thigh) and transplanted to cover the burnt area. The process is long and very painful and often a series of grafts is required. It's also not a perfect solution; the grafted skin often appears inconsistent or damaged, leaving the burn victim with a permanent reminder of their accident.
That all looks set to change however. Scientists have devised a way to 'seed' a burn or serious wound with the victim's own stem cells in a 90-minute procedure. Cells are sprayed from a 'skingun' onto the area and new skin begins to grow over the area in a matter of days. You can watch a short video clip on the procedure here.
We think that's a pretty special tech breakthrough. This alternative treatment is currently awaiting approval in the United States.
