Researchers at MIT have designed a new living material infused with cells that could one day be used as a wearable sensor, writes Brooks Hays for UPI. The researchers used the new material to “design gloves and bandages that light up when they come in contact with target chemicals.”

In this Wired video, Prof. Daniela Rus speaks about how her research group is developing and applying autonomous vehicle technology to other vehicles, in particular wheelchairs. Rus explains that she envisions the technology “impacting anyone who is confined in their motions. I see it applied in hospitals, in retirement communities, in assisted living communities.”  

In this episode of NOVA that explores how origami is being used in scientific innovations, Prof. Erik Demaine speaks about his work applying math to create new origami figures. “It’s mind blowing that the simple operation of folding lets you transform a boring square of paper into super complicated, crazy 3-D shapes," he explains. 

BBC reporter Lorelei Mihala highlights DriveWell, an app developed by Profs. Hari Balakrishnan and Sam Madden, aimed at addressing the problem of distracted driving. “We wanted to show that smartphones could be used to make drivers better,” says Balakrishnan.

TechCrunch reporter Brian Heater writes that MIT researchers have developed a speech recognition chip that uses a fraction of the power of existing technologies. “The chip is essentially designed to be always on in a low-power mode, switching over when voice is detected, thus making it ideal for technologies like wearable devices,” Heater explains.

Research affiliate Giovanni Traverso speaks with Ira Flatow of Science Friday about a new ingestible device powered by stomach acid. “When you start thinking about keeping a system inside of the body for a long time,” Traverso explains, “powering that system becomes a challenge, and that’s exactly what we tried to aim to address here with this study.”

MIT researchers have developed a pill that uses stomach acid to run sensors in the body and can deliver drugs over a long period of time, writes Hallie Smith of Boston Magazine. By attaching zinc and copper electrodes to the exterior of the pill it “reacts with stomach acid to create electricity,” explains Smith.

Dan Misener of CBC News writes that a wearable device developed by MIT researchers detects the tone of conversation by listening to the interaction and measuring the physiological responses of the user. “All of that data is fed into a neural network that's been trained to identify certain cues,” explains Misener. 

CSAIL researchers have developed a wearable system that can gauge the tone of a conversation based on a person’s speech patterns and vitals with 83 percent accuracy, writes Brian Barrett for Wired. The system could be useful for people with social anxiety or Asperger’s, Barrett explains. 

Hallie Smith writes for Boston Magazine that CSAIL researchers have developed a system that can help detect of the tone of a conversation. The system could be especially useful “for those who struggle with emotional and social cues, such as individuals with Asperger’s Syndrome,” Smith explains.

Inside Higher Ed reporter Carl Straumsheim writes that researchers from MIT and Harvard have released the latest findings from an ongoing study analyzing learner engagement and behavior in 290 MOOCs. Among other findings, researchers found that “about one-third (32 percent) of the people who participate in edX MOOCs work or used to work as teachers.”

CSAIL researchers have found that ride-sharing services could reduce the number of cars on the road by 75 percent, reports Marisa Kendall for The Mercury News. The researchers developed an algorithm that can increase service speeds by 20 percent by rerouting cars to “their most efficient routes, including automatically sending idle cars to areas of high demand.”

A new study conducted by MIT researchers shows that ride-sharing services could reduce the number of cars on the road in New York City by 75 percent, according to the BBC News. The researchers found that “a fleet of 3,000 four-passenger taxis could do the same job as the current fleet of 13,000 yellow cabs in New York City.”

A new study by MIT researchers provides evidence that if more people in New York City were willing to carpool, the city would only need 3,000 taxis, reports Hiawatha Bray for The Boston Globe. With carpooling, “we have fewer vehicles, we have less pollution and we have a better travel situation for everyone,” explains Prof. Daniela Rus. 

CSAIL researchers have found that ride-sharing taxis controlled by a citywide computer system could decrease the number of cars on the road in New York City, reports Clive Cookson for the Financial Times. The researchers found that “3,000 four-passenger cars could satisfy 98 per cent of the city’s demand.”
