Soft, synthetic retinas may offer a better implant solution

Scientists have been trying to replace retinas in otherwise healthy eyes to help people suffering from diseases like retinitis pigmentosa. Unfortunately, earlier efforts were only able to use rigid, hard materials , which are very different from the natural retina. A researcher at Oxford University, however, has created a synthetic retina made of biological materials to better match natural human tissues. The study, titled “Light-Patterned Current Generation in a Droplet Bilayer Array” was published this April in Scientific Reports . Your retina sits at the back of your eye collecting light and converting them to electrical signals for your brain. The research, led by 24-year-old Vanessa Restrepo-Schild, uses a retina made of soft water droplets called hydrogels and biological cell membrane proteins. These cells act like pixels to detect light and create a gray scale image. It can then generate electrical signals to stimulate the neurons at the back of your eye just like a natural retina does. The artificial tissues don’t contain anything other than natural, biodegradable materials, making it less likely that recipients’ bodies will reject the implant. It’s also far less invasive than devices that reproduce the system mechanically. While the new synthetic retina has only been tested in the laboratory, Restrepo-Schild hopes to continue her research to explore its potential with living tissues. That may still be a ways off, but it could surely become a more viable way than other efforts to restore sight to people with retinal issues. Via: MedicalXpress Source: Nature.com

Oleo sponge invented at Argonne National Laboratory can sop up oil in a spill

Mark Lopez/Argonne National Laboratory A group of researchers at the Argonne National Laboratory have developed a sponge that will collect oil from bodies of water, which could improve how harbors and ports are cleaned, as well as how oil spills are managed. The Oleo Sponge is made of a polyurethane foam whose interior surfaces are covered with oleophilic molecules that draw oil out of water. The challenge, according to Argonne, was finding a way to “glue” those oil-loving molecules to the sponge’s interior. That issue was tackled with the help of 2011 research from Argonne scientists , who were able to infuse metal oxide with nanostructures. The Oleo creators used that technique to develop a primer for the interior of the sponge that the oleophilic molecules stick to. The result is a sponge that can adsorb up to 90 times its weight in oil . Read 5 remaining paragraphs | Comments

ICYMI: Amazon made its first drone-powered delivery

Today on In Case You Missed It: Amazon has been testing drone deliveries for three years now, even having to move to the UK to keep it going once the FAA changed its UAV guidelines. The company released a video of its first fully autonomous drone delivery, which happened on December 7. Meanwhile a team of researchers from Los Alamos National Laboratory dug into what would happen if a sizable meteorite hit the ocean and the modeling shows a substantial amount of water vapor would get thrown into the stratosphere, which would not do great things for climate change. Finally, the Danish Neighborhood Watch came out with a robbery-preventing Christmas light and app combination to deter robbers– and provide laughs for the rest of us. If you’re looking for the dash cam video of an Uber car going through a red light, that’s here . As always, please share any interesting tech or science videos you find by using the #ICYMI hashtag on Twitter for @mskerryd.
