Researchers at MIT have created 3D-printed structures that can be controlled by a magnet. The structures included a tube that could squeeze shut, a sheet that could fold, and “a spider-like ‘grabber’ that could crawl, roll, jump, and snap together fast enough to catch a passing ball,” reports Mu Xuequan for Xinhua.
MIT researchers have developed 3-D printed magnetic robots that could potentially be used inside the body to deliver medical treatments or take tissue samples. “Their ultimate goal is to design a robot that's just as soft and flexible as a human or animal, so that it can have a wide range of potential applications,” explains Sarah Gibbens for National Geographic.
Using magnetic nanoparticles that have been mixed into rubber, Associate Prof. Xuanhe Zhao has created “3D printed shapes that fold, morph, and move in the presence of a magnetic field,” reports Leah Crane for New Scientist. In the future, Zhao believes this work could have medical applications, “like assisting minimally invasive surgeries,” notes Crane.
Using specially engineered E. coli bacteria and electronics that fit into an ingestible pill, MIT researchers have created a device that can detect internal diseases and send wireless alerts, reports Karen Kaplan for The Los Angeles Times. The device could eliminate the need for colonoscopies, which alter “the physiology inside the intestines, potentially masking signs of disease,” explains Kaplan.
USA Today reporter Sean Rossman writes about how MIT researchers have created an ingestible sensor that can monitor the digestive tract and send information to a smartphone or tablet about a person’s health. Rossman explains that the device, “can detect blood in the stomach, something that would otherwise require an endoscopy and sedation.”
MIT researchers have developed an ingestible capsule that uses genetically engineered bacteria to detect potential health problems, reports Carla Johnson for the Associated Press. The researchers hope the capsule could eventually be used to, “find signs of ulcers, inflammatory bowel disease or even colon cancer.”
Wired reporter Megan Molteni writes that a team of MIT researchers has developed an ingestible sensor that could spot gastrointestinal issues. The sensor contains, “millions of genetically engineered glowing bacteria inside a AAA-battery-sized capsule,” Molteni explains.
Writing for the Boston Herald, Lindsay Kalter reports that MIT scientists have built an ingestible capsule that could allow doctors to diagnose gastrointestinal diseases without invasive procedures. Graduate student Mark Mimee explains that the device, “sets the stage for having a pill that can give you a big biochemical profile of the gut related to various diseases.”
Popular Mechanics reporter David Grossman writes that a new ingestible medical device developed by MIT researchers could monitor the health of the human gut. Calling the project “a true team effort,” Grossman explains that it required expertise in biological engineering techniques, electronic circuit design, materials, and gastroenterology.
An international research team led by postdoctoral fellow Carl Rodriguez has found that within a group of star clusters, black hole collisions can actually create larger black holes, writes Nola Taylor Redd for Fox News. A simulation showed that these black holes “should grow to be more than 50 times as massive as Earth's sun if they collide with other black holes.”
MapLite, a system developed by CSAIL researchers, allows autonomous vehicles to drive on roads they’ve never driven before without 3D maps, writes Andrew Hawkins of The Verge. If it becomes commercial, MapLite could ensure “that the safety benefits from autonomous driving [are] extended to residents in rural communities,” suggests Hawkins.
Prof. Sara Seager speaks with Nova Wonders about the hope of finding “some sign of life” with the TESS mission. "We'd like to see methane and other gases,” says Seager. “And some of these, on their own or together, would help make the case for life on another planet.”
CSAIL researchers have developed a system that uses LIDAR and GPS to allow self-driving cars to navigate rural roads without detailed maps, writes Tracey Lindeman of Motherboard. Autonomous ride-hailing or car-sharing is important in rural communities because “the carless in these areas have few transportation options; many small communities don’t even have public buses,” notes Lindeman.
Eric Mack writes for Forbes about a new system from MIT researchers that uses GPS in conjunction with LIDAR and IMU sensors to power self-driving vehicle navigation. Graduate student Teddy Ort says the system “shows the potential of self-driving cars being able to actually handle roads beyond the small number that tech companies have mapped.”
NASA’s recently launched Transiting Exoplanet Survey Satellite (TESS) “will spend the next two years scanning 200,000 stars looking for any exoplanets orbiting them,” explains New Scientist. In about two months, once the satellite is in orbit and its cameras are tested, “there’ll just be a flood of information,” says MIT’s George Ricker, the principal investigator on TESS.
