New Scientist reporter Alex Wilkins writes that MIT researchers have developed a robotic pill that can propel itself through mucus in the intestines and could enable some injection-only medications to be taken orally. “The pill is 2.5-centimeters long and 1-centimeter wide – about the size of a large multivitamin ­– and encased in a gelatin capsule that dissolves in stomach acid,” writes Wilkins. “The pH in the lower intestine activates the motor, which is powered by a small battery.”

VulcanForms, an MIT startup co-founded by Prof. John Hart, is a 3D printing company that aims to provide cutting edge, clean and futuristic manufacturing, reports Timothy Aeppel for Reuters. “VulcanForms builds metal parts by layering on and fusing together materials bit by bit – rather than cutting them out of blocks of metal or stamping them out in metal foundries,” writes Aeppel.

NBC News reporter Kimmy Yam notes that months after having all charges he faced under the “China Initiative” dismissed, Prof. Gang Chen and his colleagues have discovered a new material that can perform better than silicon. "The discovery could have far-reaching effects, as silicon is currently among the most widely used semiconductors, making up the foundation of modern technology from computer chips to smartphones," writes Yam. 

Jamie Earl White BS ’10, MS ’12 speaks with Fast Company reporter Clint Rainey about his startup, Unit of Work, which provides free consulting to workers trying to unionize their workplaces. “Our goal is to get resources to workers in underserved workplaces, but not make them a part of our own union,” says White. “We act more like consultants who help them get where they want to be with unionizing their workplace.”

Prof. Ariel Furst, and alumna Claire Beskin and Loewen Cavill were named the winners of the first annual MIT Female Founders Pitch, reports Stephanie MacConnell for Forbes. Furst’s company, Pharmor, has developed an inexpensive protective coating that allows microbes to be produced and transported in non-ideal conditions. Beskin’s company, Empallo, uses machine learning to unlock information on siloed patient data. And Cavill’s company, AuraBlue, has developed a wearable device that can predict hot flashes and enable a cooling pad to counteract the change in body temperature in menopausal women.

Researchers at MIT believe they have found a new semiconductor that's better than silicon, which could open the doors to potentially faster and smaller computer chips in the future, reports Rachel Cheung for Vice. “Cubic boron arsenide has significantly higher mobility to both electronics and their positively charged counterparts than silicon, the ubiquitous semiconductor used in electronics and computers,” explains Cheung.

Researchers at MIT and other institutions proved “that cubic boron arsenide performs better than silicon at conducting heat and electricity,” reports Nicholas Gordon for Fortune. “The new material may help designers overcome the natural limits of current models to make better, faster, and smaller chips,” writes Gordon.

Gradiant, an MIT startup founded by Anurag Bajpayee PhD ’12, S.M. ‘08 and Prakash Govindan PhD ’12, has developed an energy efficient system that purifies water by mimicking natural rainfall cycles, reports Aaron Pressman for The Boston Globe. “Nature has the advantage of having all the surface area of the oceans available freely and a free source of energy from the sun,” Govindan said. “We have to engineer this into a compact, highly efficient, and energy-efficient industrial device.”

STAT reporter Edward Chen spotlights how MIT researchers developed a new ultrasound adhesive that can stick to skin for up to 48 hours, allowing for continuous monitoring of internal organs. “It’s a very impressive new frontier about how we can use ultrasound imaging continuously to assess multiple organs, organ systems,” said Eric Topol, the founder and director of the Scripps Research Translational Institute. “48 hours of continuous imaging, you’d have to lock somebody up in a hospital, put transducers on them. This is amazing, from that respect.”

MIT researchers have developed an adhesive ultrasound patch that can continuously image the inner workings of the body for up to 48 hours, reports Sarah Kuta for Smithsonian Magazine. ““We believe we’ve opened a new era of wearable imaging,” says Prof. Xuanhe Zhao. “With a few patches on your body, you could see your internal organs.”

The MIT mini cheetah broke a speed record after learning to adapt to difficult terrain and upping its speed, reports Rienk De Beer for Popular Mechanics.

MIT engineers have created a bioadhesive ultrasound device that can be adhered to a patient’s skin and record high-res videos of internal organs for up to two days, reports Sophie Bushwick for Scientific American. “The beauty of this is, suddenly, you can adhere this ultrasound probe, this thin ultrasound speaker, to the body over 48 hours,” says Zhao. “This can potentially change the paradigm of medical imaging by empowering long-term continuous imaging, and it can change the paradigm of the field of wearable devices.”

Researchers at MIT, led by Prof. Xuanhe Zhao, have created a wearable ultrasound medical device, reports Jeremy Hsu for New Scientist. “The ultrasound stickers may provide a more flexible imaging option for hospitals to monitor patients without requiring human technicians to hold ultrasound probes, and they could be useful in situations where technicians are in short supply,” writes Hsu.

Prof. Xuanhe Zhao and his research team have developed a stick-on ultrasound patch that can scan a person’s insides as they go about their daily life, reports Ian Sample for The Guardian. “The wearable patch, which is the size of a postage stamp, can image blood vessels, the digestive system and internal organs for up to 48 hours, giving doctors a more detailed picture of a patient’s health than the snapshots provided by routine scans,” explains Sample.

Researchers from MIT have produced a miniature ultrasound device that sticks to the body, reports Maggie Chen for Wired. “By sticking the patch on different parts of the subject’s body, the researchers could get images of the stomach, muscles, blood vessels, lungs, and heart,” explains Chen.
