'Smart' contact lenses could someday enable wireless glaucoma detection      (via sciencedaily.com)     Original source 

Most people with early-stage glaucoma don't know they have it, even though early treatment is key to reducing vision loss. While detecting a subtle increase in eye pressure helps doctors to diagnose glaucoma, it's challenging to monitor continuously, especially with the variety of temperatures eyes experience. Now, researchers report a prototype 'smart' contact lens that measures eye pressure accurately, regardless of temperature.

Generative AI that imitates human motion      (via sciencedaily.com)     Original source 

Walking and running is notoriously difficult to recreate in robots. Now, a group of researchers has overcome some of these challenges by creating an innovative method that employs central pattern generators -- neural circuits located in the spinal cord that generate rhythmic patterns of muscle activity -- with deep reinforcement learning. The method not only imitates walking and running motions but also generates movements for frequencies where motion data is absent, enables smooth transition movements from walking to running, and allows for adapting to environments with unstable surfaces.

'Wraparound' implants represent new approach to treating spinal cord injuries      (via sciencedaily.com)     Original source 

A tiny, flexible electronic device that wraps around the spinal cord could represent a new approach to the treatment of spinal injuries, which can cause profound disability and paralysis. A team of engineers, neuroscientists and surgeons developed the devices and used them to record the nerve signals going back and forth between the brain and the spinal cord. Unlike current approaches, the new devices can record 360-degree information, giving a complete picture of spinal cord activity.

Swarms of miniature robots clean up microplastics and microbes, simultaneously      (via sciencedaily.com)     Original source 

When old food packaging, discarded children's toys and other mismanaged plastic waste break down into microplastics, they become even harder to clean up from oceans and waterways. These tiny bits of plastic also attract bacteria, including those that cause disease. Researchers describe swarms of microscale robots (microrobots) that captured bits of plastic and bacteria from water. Afterward, the bots were decontaminated and reused.

Why is breaking down plant material for biofuels so slow?      (via sciencedaily.com)     Original source 

Tracking individual enzymes during the breakdown of cellulose for biofuel production has revealed how several roadblocks slow this process when using plant material that might otherwise go to waste. The research may lead to new ways to improve the breakdown process and make the non-edible parts of plants and other plant waste, such as forestry residue, a more competitive source of biofuels.

'Better than graphene' material development may improve implantable technology      (via sciencedaily.com)     Original source 

Move over, graphene. There's a new, improved two-dimensional material in the lab. Borophene, the atomically thin version of boron first synthesized in 2015, is more conductive, thinner, lighter, stronger and more flexible than graphene, the 2D version of carbon. Now, researchers have made the material potentially more useful by imparting chirality -- or handedness -- on it, which could make for advanced sensors and implantable medical devices.
