Experimental Brain Implant Lets Paralyzed People Communicate by Turning Thoughts Into Text

People with paralysis could someday use a brain implant to help them communicate their thoughts and carry out everyday tasks. As Engadget reports, a brain-computer interface (BCI) called the BrainGate2 Neural Interface System has enabled three paralyzed people to send texts, buy groceries online, stream music, and even play a virtual piano on a tablet.

The interface was developed by the BrainGate consortium, a team of neuroscientists, engineers, and computer scientists that creates new technologies for people who are paralyzed, have lost a limb, or have a neurologic disease that limits their motor function or speaking ability. Their findings were published in the journal PLOS One.

The three participants in the clinical study are paralyzed and lack the use of their arms. An implant about the size of a baby aspirin pill containing an array of microelectrodes was placed in their motor cortex—the part of the brain responsible for movement. A small sensor was used to record any neural signals associated with moving a limb, which were then decoded and sent to a virtual mouse paired to a tablet via Bluetooth.

In other words, the participants just had to think about moving a cursor on a screen, and the interface did the heavy lifting for them. They were able to type 30 characters per minute and make 22 point-and-click selections per minute.

Similar technologies have been developed in the past, but this one lets people use an off-the-shelf tablet without having to make any modifications, according to Engadget.

Although the brain implant technology is still in the experimental stage and is not yet ready for commercial development, several of the study’s authors said the results are promising and could vastly improve the quality of life for people with paralysis.

Stanford University bioengineer and lead author Paul Nuyujukian said in a statement, "One of the participants told us at the beginning of the trial that one of the things she really wanted to do was play music again. So, to see her play on a digital keyboard was fantastic."

Now that Prime Day is over, and with Black Friday and Cyber Monday still a few weeks away, online deals may seem harder to come by. And while it can be a hassle to scour the internet for promo codes, buy-one-get-one deals, and flash sales, Amazon actually has an extensive coupon page you might not know about that features deals to look through every day.

As pointed out by People, the coupon page breaks deals down by categories, like electronics, home & kitchen, and groceries (the coupons even work with SNAP benefits). Since most of the deals revolve around the essentials, it's easy to stock up on items like Cottonelle toilet paper, Tide Pods, Cascade dishwasher detergent, and a 50 pack of surgical masks whenever you're running low.

But the low prices don't just stop at necessities. If you’re looking for the best deal on headphones, all you have to do is go to the electronics coupon page and it will bring up a deal on these COWIN E7 PRO noise-canceling headphones, which are now $80, thanks to a $10 coupon you could have missed.

Alternatively, if you are looking for deals on specific brands, you can search for their coupons from the page. So if you've had your eye on the Homall S-Racer gaming chair, you’ll find there's currently a coupon that saves you 5 percent, thanks to a simple search.

To discover all the deals you have been missing out on, head over to the Amazon Coupons page.

The Northern Lights Storms Are Getting Names—and You Can Offer Up Your Suggestions

While all northern lights are spectacular, they’re not all spectacular in the same way. Aurora borealis, or “northern dawn,” occurs when electrons in the magnetic field surrounding Earth transfer energy to oxygen and nitrogen molecules in the atmosphere. The molecules then emit the excess energy as light particles, which create scintillating displays whose colors and shapes depend on many known and unknown factors [PDF]—type of molecule, amount of energy transferred, location in the magnetosphere, etc.

Though the “storms” are extremely distinct from each other, they haven’t been named in the past the way hurricanes and other storms are christened. That’s now changing, courtesy of a tourism organization called Visit Arctic Europe. As Travel + Leisure reports, the organization will now christen the strongest storms with Nordic names to make it easier to keep track of them.

“There are so many northern lights visible in Arctic Europe from autumn to early spring that we started giving them names the same way other storms are named. This way, they get their own identities and it’s easier to communicate about them,” Visit Arctic Europe’s program director Rauno Posio explained in a statement.

Scientists will be able to reference the names in their studies, much like they do with hurricanes. And if you’re a tourist hoping to check out other people’s footage of the specific sky show you just witnessed, searching by name on social media will likely turn up better results than a broad “#auroraborealis.”

Visit Arctic Europe has already given names to recent northern lights storms, including Freya, after the Norse goddess of love, beauty, and fertility, and Sampo, after “the miracle machine and magic mill in the Finnish national epic poem, ‘Kalevala.’” A few other monikers pay tribute to some of the organization’s resident “aurora hunters.”

But you don’t have to be a goddess or an aurora hunter in order to get in on the action. Anybody can submit a name (along with an optional explanation for your suggestion) through the “Naming Auroras” page here. It’s probably safe to assume that submissions related to Nordic history or culture have a better chance of being chosen, but there’s technically nothing to stop you from asking Visit Arctic Europe to name a northern lights show after your dog.
