MIT researchers have created “a vibrating pill that stimulates nerve endings in the stomach to tell the brain it’s time to stop eating,” reports Mitch Leslie for Science. “A gel plug in the pill keeps the motor from switching on,” explains Leslie. “But the gel dissolves rapidly when it contacts stomach fluid, allowing the motor to start turning. When that happens, the pill shakes for about 38 minutes, roughly the amount of time it would stay in the stomach. The researchers hypothesized that these vibrations would stimulate the stretch-sensing nerve endings and signal satiety.”

Newsweek reporter Pandora Dewan spotlights MIT researchers and their work developing an ingestible vibrating pill that can mimic the sensation of fullness. "The development of new non-invasive methods for treating obesity is of importance in confronting the multifaceted challenges posed by this global health crisis," says Shriya Srinivasan PhD ’20. "Traditional interventions, such as invasive surgeries, can be associated with significant risks, costs and lifestyle modifications, limiting their applicability and effectiveness.”

Researchers at MIT have developed a vibrating pill that can be swallowed before eating to create a feeling of fullness, reports Nicola Davis for The Guardian. “This approach offers an alternative and potentially synergistic approach to other therapies available today,” says Prof.  Giovanni Traverso.

Researchers at MIT have developed “a battery-operated capsule-like device that’s supposed to make you feel full by stretching out your stomach using vibration,” reports Miriam Fauzia for Inverse. “Considering that diet and exercise are hard to maintain, especially for long-term weight loss, and medical interventions like gastric bypass surgery and the newest wave of injectables cost more than a pretty penny, [Shriya] Srinivasan PhD ’20 and her colleagues want their vibrating pill to be an accessible alternative,” writes Fauzia.

Forbes contributor William Haseltine spotlights how MIT researchers developed a biosensor ingestible capsule that can gather and transmit information on a patient’s condition to a physician. Haseltine notes that “aside from respiratory and heart rate monitoring, future applications for the pill could come from alterations in its design, leading to other avenues of health monitoring. These may include digestive health, blood sugar monitoring and cancer cell detection.” 

Fast Company reporter Adele Peters spotlights how researchers at MIT have combined cement with carbon black to make concrete that can store energy as one of the climate tech innovations that provide hope “that it’s still possible to avoid the worst impacts of climate change.” With this new technology, “the foundation of your future house could eventually store solar power from your roof,” explains Peters.

Researchers from MIT and elsewhere are developing an electronic pill that can “measure heart rate, breathing rate and core temperature – from inside a human stomach,” reports Celia Ford for Wired. “We have a solution that’s relatively simple and enables access broadly,” says Prof. Giovanni. “I think that can be really transformative.”

Prof. Ritu Raman has developed centimeter-scale robots that use biological muscle, reports Liam Drew for Nature. “Raman is now developing muscle systems connected to neurons that can trigger contraction, just as they exist in animals,” writes Drew. “In the longer term, she aims to use networks of biological neurons that can sense external stimuli as well, enabling them to move in response to environmental cues.”

MIT researchers have developed a, “new laser-based technique that could speed up the discovery of promising metamaterials for real-world applications,” reports Andrew Corselli for Tech Briefs. The technique “offers a safe, reliable, and high-throughput way to dynamically characterize microscale metamaterials, for the first time,” reports Corselli.

Alumnus Dave Dussault founded Snapchill, a hot coffee company that uses technology to brew, “the best of both hot coffee and cold brew,” reports Grant Welker for NBC Boston. “The technology entails brewing the coffee hot, then dropping the temperature in a matter of seconds from more than 200 degrees to just above freezing,” explains Welker. “It's done using what Dussault said is essentially the same technology used in a refrigerator.”

Researchers from MIT and elsewhere have developed a swallowable “technopill” that can monitor vital signs from inside the body, reports Dennis Thompson for HealthDay. “The ability to facilitate diagnosis and monitor many conditions without having to go into a hospital can provide patients with easier access to healthcare and support treatment,” says Prof. Giovanni Traverso.

Prof. Russ Tedrake and Max Bajracharya '21 MEng '21 speak with TechCrunch reporter Brian Heater about the impact of generative AI on the future of robotics. “Generative AI has the potential to bring revolutionary new capabilities to robotics,” says Tedrake. “Not only are we able to communicate with robots in natural language, but connecting to internet-scale language and image data is giving robots a much more robust understanding and reasoning about the world.”

MIT researchers have developed a supercapacitor comprised of concrete and charcoal, that can store electricity and discharge as needed, reports Aleks Phillips for Newsweek. Researchers hope the device can provide “a cheap and architectural way of saving renewable energy from going to waste,” writes Phillips.

New Scientist reporter Alice Klein writes that MIT researchers have developed an ingestible electronic device that “can measure your breathing and heart rate from inside your gut [and] could potentially diagnose sleep apnea and even detect opioid overdoses.” The device could one day allow “people to be assessed for sleep apnea wirelessly and cheaply while at home.”

Researchers at MIT and elsewhere have developed a new type of cancer treatment – a gel that can be used to deliver cancer drugs for solid tumors, reports WHDH. “It’s really transformative to try and help patients whose tumors are very resistant to therapy,” says Prof. Giovanni Traverso.
