How Two Paralyzed Patients Walked Again Without Surgery

Posted by in categories: biotech/medical, cyborgs, robotics/AI, space

The protocol, dubbed Walk Again Neuro-Rehabilitation (WA-NR), first uses EEG to record and control virtual avatars and robotic exoskeleton walkers while the patient wears a “tactile shirt” that offers them sensory feedback. This stimulation theoretically teaches damaged nerves to reroute their motor functions to healthy ones. Following the program for just three years, the patients—some paralyzed for decades—dramatically regained sensation in their lower limbs. They could feel where their legs were in space and better control their lower limbs. Some even reported feelings of normal, welcomed pain after a sharp jab.

The current study, published in Scientific Reports, takes neurorehab a step further. In two patients from the original cohort, the team further trained and examined their neuro-recovery in detail. Patient P1 was a middle-aged man paralyzed for 4.5 years at the onset of the study; P2, a 32-year-old, had been paralyzed for a decade. Although trained with WA-NR, both patients scored on the low end of overall movement, with the ability to extend their knees at most.

For each training session, the patients wore an EEG cap to measure movement intent and had eight electrodes placed on the skin of each leg to stimulate muscles. Simultaneously they wore a haptic shirt, which gave them a sense of their body in space by stimulating their forearms.

Amazon says drone deliveries coming ‘within months’

Posted by in categories: drones, robotics/AI, space

Amazon said Wednesday it expects to begin large-scale deliveries by drone in the coming months as it unveiled its newest design for its “Prime Air” fleet.

Jeff Wilke, head of Amazon’s consumer operations, told the company’s Machine Learning, Automation, Robotics and Space conference in Las Vegas that drones would play a role in ramping up efforts to shorten delivery times for many items to just one day for Amazon Prime members.

“We’ve been hard at work building fully electric drones that can fly up to 15 miles (25 kilometers) and deliver packages under five pounds (2.3 kilos) to customers in less than 30 minutes,” Wilke said in a blog post.

Chinese scientists make breakthrough in injectable cartilage

Posted by in categories: innovation, space

(ECNS) — The Chinese team that constructed the world’s first ear in a lab and grafted it onto a patient last year has made new progress by developing injectable cartilage that can be used in human tissue repair and plastic surgery.

The regeneration technique involves taking a small part of cartilage tissue from behind the ear of a patient, culturing seed cells in the lab and reproducing cells in a sufficient amount to fill a biodegradable mould made by 3D-printing.

Professor Cao Yilin, director of National Tissue Engineering Research Center, said it marks a breakthrough from previous technology as the cultured cells can be injected into a patient’s body parts like the nose and chin where they continue to develop into normal tissue, a minimally invasive treatment similar to natural growth.
