Researchers Help a Paralyzed Man Regain Hand Movement Through Neural Bypass Thechnology

Ian Burkhart is one of 250,000 Americans with spinal cord injuries. Four years ago he was hurt in a swimming accident that left him paralyzed below the shoulders, but a new technology developed by the Feinstein Institute for Medical Research in Manhasset, New York has given him the ability to move his hands and wrists again. It’s called neural bypass and it may hold the key to helping people with spinal cord injuries regain their movement.

At the onset of the study, researchers implanted an array of electrodes in the left primary motor cortex in Burkhart’s brain. The implant was then connected to wires that bypassed his damaged nerve pathways and connected directly to muscles in his hand, wrists and fingers. After 15 months, Burkhart learned how to send the proper signals to specific muscle groups and was able to perform the complex task of pouring water into a bottle into and then stirring it.

“The first time I was able to move my hand it was a big shock,” Burkhart says. “It was something that I hadn’t moved in about three and a half years at that point. And now it’s something that’s so fluid it’s kind of like it was before I had my injury.” He then learned how to swipe a credit card and play the video game Guitar Hero. “Our goal was to use this technology so that these patients like Ian can be more in charge of their lives and can be more independent,” Ali Rezai, one of the researchers at Feinstein Institute, said in a statement. “This really provides hope, we believe, for many patients in the future.”

Although the results of the tests are promising, researchers are emphasizing that neural bypass devices cannot restore feeling. Also, because the implants are invasive, they’re will not be recommended for paraplegics in poor health. But researchers are hopeful the technology can be developed into a wireless system that will help patients move without the cumbersome wires.

If you are totally ready to move on from Donald Trump, you're not alone. According to a report last April from the Wason Center National Survey of 2020 Voters, "President Trump will be the least popular president to run for reelection in the history of polling."

Yes, you read that right, "history of polling."

After three years on the sidelines, Colin Kapernick will be working out for multiple NFL teams on Saturday, November 16 at the Atlanta Falcons facility.

The former 49er quarterback who inflamed the culture wars by peacefully protesting against social injustice during the national anthem made the announcement on Twitter Tuesday.

Kaepernick is scheduled for a 15-minute on-field workout and an interview that will be recorded and sent to all 32 teams. The Miami Dolphins, Dallas Cowboys, and Detroit Lions are expected to have representatives in attendance.

"We like our quarterback situation right now," Miami head coach, Brian Flores said. "We're going to do our due diligence."

NFL Insider Steve Wyche believes that the workout is the NFL's response to multiple teams inquiring about the 32-year-old quarterback. A league-wide workout would help to mitigate any potential political backlash that any one team may face for making an overture to the controversial figure.

Kapernick is an unrestricted free agent (UFA) so any team could have reached out to him. But it's believed that the interested teams are considering him for next season.

Earlier this year, Kaepernick and Carolina Panthers safety Eric Reid reached a financial settlement with the league in a joint collusion complaint. The players alleged that the league conspired to keep them out after they began kneeling during the national anthem in 2016.

Before the 2019 season, Kaepernick posted a video of himself working out on twitter to show he was in great physical condition and ready to play.

Kaepnick took the 49ers to the Super Bowl in 2012 and the NFC Championship game in 2013.

He has the 23rd-highest career passer rating in NFL history, the second-best interception rate, and the ninth-most rushing yards per game of any quarterback ever. In 2016, his career to a sharp dive and he won only of 11 games as a starter.


In the category of "claims to fame nobody wants," the United States can now add "exporter of white supremacist ideology" to its repertoire. Super.

Russell Travers, acting director of the National Counterterrorism Center, made this claim in a briefing at The Washington Institute in Washington, D.C. "For almost two decades, the United States has pointed abroad at countries who are exporters of extreme Islamist ideology," Travers said. "We are now being seen as the exporter of white supremacist ideology. That's a reality with which we are going to have to deal."

Between Alexa, Siri, and Google, artificial intelligence is quickly changing us and the way we live. We no longer have to get up to turn on the lights or set the thermostat, we can find the fastest route to work with a click, and, most importantly, tag our friends in pictures. But interacting with the world isn't the only thing AI is making easier – now we can use it save the world, too.
