MIT startup Ministry of Supply has developed a jacket that utilizes AI to keep its wearer warm. “The jacket…can also be voice-controlled through devices like the Amazon Echo or manually with an app,” writes Erin Black for CNBC.

Prof. Michael Strano has developed a new device that generates electricity by harnessing energy from temperature changes. Elements that usually hinder the effectiveness of solar panels, like clouds or sand, “wouldn’t affect [this device's] ability to harness power from the ever-changing temperatures,” explains Sydney Pereira of Newsweek.

New research shows that using volcanic ash in cement mixtures could enable “stronger and more environmentally friendly” construction in future cities, reports Sydney Periera for Newsweek. “There may be a tremendous implication of energy savings at the city scale,” Prof. Oral Büyükoztürk tells Periera.

MIT researchers have designed a new chip that could advance the development of computers that operate like the human brain, reports James Vincent for The Verge. The development could, “lead to processors that run machine learning tasks with lower energy demands — up to 1,000 times less. This would enable us to give more devices AI abilities like voice and image recognition.”

AP reporter Lauran Neergaard writes that MIT researchers have developed a hair-thin implant that can deliver medications to specific regions of the brain. Neergaard writes that the device, “could mark a new approach to treating brain diseases — potentially reducing side effects by targeting only the hard-to-reach circuits that need care.”

WCVB reporter Mike Wankum visits Embr Labs, an MIT spinoff that has developed a wristband that can make wearers feel warmer or colder. Wankum explains that after a few minutes of wearing the wristband, “you feel more comfortable. Much like holding a warm cup of coffee to take the chill off a winter morning.”

In an article for NBC News about solar power, Corey Powell highlights Prof. Jeffrey Grossman’s work developing a material for a new chemical heat battery that could release energy on demand. “We’re creating materials that store thermal energy in completely new ways,” Grossman explains. 

Scientific American reporter Prachi Patel writes that a new study by Prof. Elsa Olivetti found that demand for cobalt, which is critical to electric vehicle batteries, could soon outstrip supply. “The best lithium battery cathodes [negative electrodes] all contain cobalt, and its production is limited,” Olivetti explains. 

Researchers at MIT have developed a process that can produce strong ultrafine nanofibers that can potentially be used in armor, reports Xinhua. The newly developed fibers “combine the desirable qualities of strength, stiffness and toughness in ways that outperform glass fibers or steel wire,” the article explains.

MIT researchers have developed a new technique to 3-D print genetically engineered bacteria into a variety of shapes and forms, reports Karen Hao for Quartz. The technique could eventually be used to develop such devices as, “an ingestible living robot that secretes the correct drug when it detects a tumor.”

MIT engineers have developed a method to 3-D print living cells into tattoos and 3-D structures, reports Danny Paez for Inverse. Paez explains that the researchers believe the technique, “could possibly be used to create a ‘living computer,’ or a structure made up of living cells that can do the stuff your laptop can.”

Co.Design reporter Katharine Schwab writes that MIT researchers have developed a tattoo made of living cells that activate when exposed to different kinds of stimuli. Schwab explains that in the future the tattoos could be designed, “so that they respond to environmental pollutants or changes in temperature.”

Martin Finucane of The Boston Globe reports that MIT researchers are developing a method to allow oil and water to mix. Using a combination of a surfactant and condensation, “tiny water droplets form on the surface that sink into the oil and stay mixed for months, rather than separating in just a few minutes,” explains Finucane. 

HuffPost reporter Thomas Tamblyn writes that MIT researchers have developed a new “air-breathing” battery that can store electricity for months. The new battery could harvest, “the vast wind energy waiting to be captured in the North Atlantic, store it for months on end and then release it into the grid for a fraction of the cost that we’re currently paying.”

WGBH’s Adam Reilly visits MIT spinout Embr Labs, where researchers have developed a wristband that helps the wearer feel warmer or cooler, and could also help reduce energy consumption. "Even if we could help people use their AC unit and their heating just a fraction of a degree less, the benefits for the world could be tremendous,” explains co-founder and MIT graduate David Cohen-Tanugi.
