Watch This Monkey Control a Wheelchair With Its Mind

The future of brain-controlled robotics is here, and it is so accessible, even a monkey can handle it. According to Gizmodo, researchers have developed a wireless brain-machine interface (BMI) that gives monkeys the ability to control a robotic wheelchair, just by thinking about where they want it to go. The scientists believe that the findings of the study, recently published in Nature Scientific Reports, could lead to great new developments that could potentially "restore whole body mobility to severely paralyzed patients."

For the research, the scientists, led by Duke University neurobiologist Miguel Nicolelis, implanted wireless devices into the brains of two rhesus monkeys in the regions responsible for sensations and movement. Then, they preprogrammed machine routes to a reward (in this case, grapes). Eventually, the monkeys learned how to navigate the wheelchairs freely, as demonstrated in the video above. In fact, the primates, nicknamed “M” and “K”, were wheeling around at speeds of up to 11 inches per second. During the entire process, Nicolelis and his team monitored their brain activity.

What sets this study apart from previous studies, according to Nerdist, is that the monkeys did not have to teach their brains to control the machine by first moving their own bodies. "This means that even if people have no control over their limbs or muscles, they’ll still be able to learn how to control external machines," Matthew Hart writes.

The study is a part of the larger Walk Again Project by Miguel Nicolelis of Duke Health, a nonprofit focused on brain interface tech. "The current results promise much more than a mere demonstration that monkeys can control whole body navigation," the researchers write. They argue that their findings support the idea that "when paraplegic patients are subjected to intense BMI training, they not only became capable of regaining walking, using a robotic exoskeleton, but they also can exhibit signs of partial neurological recovery of sensorimotor and autonomic functions."

Could Imported Sperm Help Save America’s Bees?

It might be time to call in some sexual backup for male American bees. Scientists have started impregnating domestic honeybees with foreign sperm in the hopes that enlarging the gene pool will give our bees a fighting chance.

These days, the bees need all the help they can get. Colonies across the globe are disappearing and dying off, partly due to the increased use of neonicotinoid pesticides and partly from a parasite called the varroa mite. The invasive mite first landed on American shores in 1987, and it's been spreading and sickening and devouring our bees ever since.

Part of the problem, researchers say, is that the American bee gene pool has gone stagnant. We stopped importing live honeybees in 1922, which means that all the bees we've got are inbred and, therefore, all alike. They lack the genetic diversity that allows species to adapt to changing conditions or new threats. So when the mites come, they all get hit.

Many apiarists now rely on anti-mite pesticides to keep their charges safe. While these treatments may help keep the mites away, they aren't great for the bees, either—and the mites have begun to develop a resistance. But beekeepers feel like their hands are tied.

"I lost 40 percent of my colonies to varroa last fall," Matthew Shakespear of Olson's Honeybees told NPR. "I'm not taking any more chances. We've already done five treatments, compared with the two treatments we applied this time last year."

But there might be another way. Experts at the University of Washington have started to—how can we put this delicately?—manually encourage drones (male bees) in Europe and Asia to give up their sperm. All it takes is a little belly rub, and the drone, er, donates 1 microliter of fluid, or one-tenth of the amount needed to inseminate a queen bee.

Fortunately, the bees don't mind at all. "They're really accommodating," bee breeder and researcher Susan Cobey told NPR.

So far, the scientists' attempts to crossbreed foreign and domestic bees have been successful. Within their test colonies, genetic diversity is up.

"This doesn't mean they are superior in performance to the other bees," researcher Brandon Hopkins said. "It means we have a better chance of finding rare and unique traits." Traits, Hopkins says, like genetic resistance to the varroa mites—a quality shared by donor bees in Italy, Slovenia, Germany, Kazakhstan, and the Republic of Georgia.

Other beekeepers are opting for a more hands-off approach, introducing imported queens to their domestic hives. Shakespear bought his from Cobey, who reared them from bees she collected in Slovenia.

"Maybe these new genetics can deal with the varroa mites naturally," Shakespear said, "rather than having to rely on chemicals. It's time to start widening our gene pool."

London's Natural History Museum Has a New Star Attraction: An Amazing Blue Whale Skeleton

Natural History Museum

In January 2017, London’s Natural History Museum said goodbye to Dippy, the Diplodocus dinosaur skeleton cast that had presided over the institution’s grand entrance hall since 1979. Dippy is scheduled to tour the UK from early 2018 to late 2020—and taking his place in Hintze Hall, The Guardian reports, is a majestic 82-foot blue whale skeleton named Hope.

Hope was officially unveiled to the public on July 14. The massive skeleton hangs suspended from the hall’s ceiling, providing visitors with a 360-degree view of the largest animal ever to have lived on Earth.

Technically, Hope isn’t a new addition to the Natural History Museum, which was first established in 1881. The skeleton is from a whale that beached itself at the mouth of Ireland's Wexford Harbor in 1891 after being injured by a whaler. A town merchant sold the skeleton to the museum for just a couple of hundred pounds, and in 1934, the bones were displayed in the Mammal Hall, where they hung over a life-size blue whale model.

The whale skeleton remained in the Mammal Hall until 2015, when museum workers began preparing the skeleton for its grand debut in Hintze Hall. "Whilst working on the 221 bones we uncovered past conservation treatments, such as the use of newspaper in the 1930s to fill the gaps between the vertebrae," Lorraine Cornish, the museum's head of conservation, said in a statement. "And we were able to use new methods for the first time, including 3D printing a small number of bones missing from the right flipper."

Once restoration was complete, Hope was suspended above Hintze Hall in a diving position. There she hangs as one of the museum’s new major attractions—and as a reminder of humanity’s power to conserve endangered species.

"The Blue Whale as a centerpiece tells a hopeful story about our ability to create a sustainable future for ourselves and other species," according to a museum press release. "Humans were responsible for both pushing the Blue Whale to the brink of extinction but also responsible for its protection and recovery. We hope that this remarkable story about the Blue Whale will be told by parents and grandparents to their children for many years to come, inspiring people to think differently about the natural world."
