Handheld Device Fights Fatigue by Stimulating Vagus Nerve

by inspectAR in Engineering, Engineering News

Feeling tired? Applying electricity to a nerve in the neck with a handheld device can reduce fatigue and improve multitasking in sleep-deprived people, according to a new study conducted on U.S. Air Force volunteers. Previous research found that electrically stimulating the brain with a technique known as transcranial direct current stimulation can improve mental performance […]

Brain-Computer Interface Smashes Previous Record for Typing Speed

by Susan K. Kathy Land in Engineering, Engineering News

The ancient art of handwriting has just pushed the field of brain-computer interface (BCI) to the next level. Researchers have devised a system that allows a person to communicate directly with a computer from his brain by imagining creating handwritten messages. The approach enables communication at a rate more than twice as fast as previous typing-by-brain experiments. […]

Inovio’s Electrical Device Zaps a COVID-19 Vaccine Into the Body

by steven cherry in Engineering, Engineering News

Spencer Lowell It took a global pandemic to accomplish one of the most significant advances in the history of vaccinology: widespread, commercial deployment of vaccines derived from nucleic acids. As of this writing, hundreds of millions of people have been vaccinated against SARS-CoV-2, the virus that causes COVID-19. And most of those shots have been […]

Wearable Sensor Tracks How Much You Scratch

by emily waltz in Engineering, Engineering News

How much does it itch? That’s a question doctors often ask people with eczema and other itch-inducing ailments, but the answer is subjective and hard to quantify; like being asked to rate one’s pain using one of those emoji-face pain scales. Today researchers report in Science Advances a wearable sensor that can accurately quantify how much a person […]

Brain Signals Can Drive Exoskeleton Parts Better With Therapy

by stephen cass in Engineering, Engineering News

Neural control might one day help patients operate robotic prosthetics by thought. Now researchers find that with the help of physical therapy, patients could accomplish more with such neural control than scientists previously knew was possible. Around the world, research teams are developing lower-body exoskeletons to help people walk. These devices are essentially walking robots […]

Lasers To Lunar Arks: Cryopreservation Heats Up

by evan ackerman in Engineering, Engineering News

When scientists in the 1950s tried to cool hamsters to 0 °C and rewarm them, it didn’t go great. In 2002, things looked rosier when a scientist chilled a single rabbit kidney down to -130°C, then rewarmed it and transplanted it into a live rabbit, where it worked for 48 days. Then not much else […]

How People with Paralysis Can Command Computers Wirelessly With Their Minds

by michelle hampson in Engineering, Engineering News

In 2015, the BrainGate initiative hit a milestone when volunteers with tetraplegia were able to type using their minds. But, to accomplish this feat, participants had to be connected to a stationary computer in order for the immense amount of data to be transmitted for processing. In a more recent breakthrough, BrainGate researchers have succeeded in creating a wireless brain-computer […]

Smartphone Camera Senses Patients' Pulse, Breathing Rate

by Engineering Recruiting in Engineering, Engineering News

Telehealth visits increased dramatically when the pandemic began—by over 4000% in the U.S., by one account. But there’s a limit to what doctors can accomplish during these virtual appointments. Namely, they can’t check patients’ vital signs over the phone. But new technologies in the works could change that by equipping phones with reliable software that can measure […]

Robotic Exoskeletons Could One Day Walk By Themselves

by charles q. choi in Engineering, Engineering News

Engineers, using artificial intelligence and wearable cameras, now aim to help robotic exoskeletons walk by themselves. Increasingly, researchers around the world are developing lower-body exoskeletons to help people walk. These are essentially walking robots users can strap to their legs to help them move.
