Glaciers are one of the largest reservoirs of freshwater on our planet, and their melting or growing is one of the best indicators of climate change. However, knowledge of glacier change has been hampered by lack of data, especially for understanding regional behaviour.
More than a decade after losing her eyesight, Carmen Torres can finally see again, thanks to a bionic eye and a first-of-its-kind surgery.
“I was happy and I was just laughing like crazy,” Torres told reporters at the Bascom Palmer Eye Institute in Miami on Friday, describing what it felt like to see light after so many years in the dark. “It was very emotional, but I’m very strong. I didn’t cry.”
Torres, 58, began losing her sight at the age of 18 due to retinitis pigmentosa, a degenerative genetic disease in which eyesight degrades over time. By the time she reached 45 she was completely blind, the Miami Herald reports.
Things began to look up in November of last year, when Torres underwent a procedure to install the Argus II Retinal Prosthesis System, in the first surgery of its kind in Florida.
Her doctor acknowledged the procedure itself was fairly complicated and involved many intricate steps.
“It’s a meticulous technique,” Dr. Nina Gregori told reporters, one that requires “exact, precise measurements of where to place these components on the eye and we really took our time.”
The system works by translating images from a small video camera affixed to Torres’ glasses into electrical signals, which are then beamed to a tiny implant in her eye. Those electrical impulses stimulate the retina and the brain interprets them as light, allowing Torres to “see.”
Only about 100 patients worldwide have received the implant so far, according to the hospital. The system received approval from the Food and Drug Administration in 2013.
Over time, Torres learned how to understand the visuals — which she said was —> Read More

We’ve never seen a comet as close as this. Taken shortly before touchdown by the Philae lander on November 12, 2014, you’re looking across a scene just 32 feet from side to side (9.7-meters) or about the size of a living room. Part of the lander is visible at upper right. Credit: ESA/Rosetta/Philae/ROLIS/DLR
With just 12 days before Comet 67P/Churyumov-Gerasimenko reaches perihelion, we get a look at recent images and results released by the European Space Agency from the Philae lander along with spectacular 3D photos from Rosetta’s high resolution camera. (…)

The Rosetta orbiter is continuing its science until the end of the extended Rosetta mission in September 2016. The lander’s future is less certain. This film covers some of what we’ve learnt from Philae about comet 67P/Churyumov-Gerasimenko so far.
