Engineers have developed flexible, ultralight solar cells that can turn any surface into a power source. These durable devices, which are much thinner than a human hair, are glued to a strong, lightweight fabric, making them easy to install on a surface. mitsha.re/aeHL50M0VHg

A new method lets users search a remote database without revealing the information they are seeking to the server. “This work is really about giving users back some control over their own data,” says Alexandra Henzinger. mitsha.re/lBme50LXtPF

A new machine-learning model simulates how a listener would hear a sound from any point in a room. “I think this work opens up an exciting research direction on better utilizing sound to model the world,” Yilun Du says. mitsha.re/LHHL50LqJAf

MIT engineers build a battery-free, wireless underwater camera: The device could help scientists explore unknown regions of the ocean, track pollution, or monitor the effects of climate change. mitsha.re/S8hL50KUwA8

Federated learning is a collaborative method for training a machine-learning model that keeps sensitive user data private. Hundreds or thousands of users each train their own model using their own data on their own device. mitsha.re/1vwM50KI3RV

Researchers from MIT and elsewhere developed a machine-learning model that can answer university-level mathematics problems in a few seconds at a human level. mitsha.re/4uwP50KbAiI

Researchers discover major roadblock in alleviating network congestion: Algorithms designed to ensure multiple users share a network fairly can’t prevent some users from hogging all the bandwidth. mitsha.re/3jEt50KeQKX

New algorithm aces university math course questions: Researchers use machine learning to automatically solve, explain, and generate university-level math problems at a human level. mitsha.re/4uwP50KbAiI

“Additive manufacturing can make a big difference in the future of space hardware,” says Luis Fernando Velásquez-García, whose team has 3D printed sensors for satellites. Such sensors could help scientists predict the weather or study climate change. mitsha.re/Nxve50K5qlB

'Explanations make people, both experts & nonexperts, overconfident in the ability or the advice of a specific recommendation system.” — #JameelClinic PI Marzyeh tells Adam Zewe for MIT News news.mit.edu/2022/explained…

Smart textiles sense how their users are moving: Researchers develop a comfortable, form-fitting fabric that recognizes its wearer’s activities, like walking, running, and jumping. mitsha.re/ijhA50JQqux

LIDS researchers are helping to make features used in machine-learning models more understandable for end users. “Out in the real world,” Alexandra Zytek says, “there is still a lot of confusion stemming from the features, not from the model itself.” mitsha.re/tXh450JLvsE

A new robotic system uses radio frequency signals, computer vision, and complex reasoning to efficiently find items hidden under a pile. Its algorithms locate more hidden items than other sophisticated robotic systems, and in half the time. mitsha.re/lPIN50JKzGZ

Researchers have created a technique that boosts the speeds of programs that run in the Unix shell, a ubiquitous programming environment created 50 years ago, by parallelizing the programs. mitsha.re/tlwG50Jsumm

Inspired by fireflies, EECS researchers have created insect-scale robots that can emit light when they fly, which enables motion tracking and communication. “It only takes about 3 percent more energy to shine out light,” Kevin Chen says. mitsha.re/QxBy50JCCZf

Stronger security for smart devices: Researchers demonstrate two security methods that efficiently protect analog-to-digital converters from powerful attacks that aim to steal user data. mitsha.re/ZNIe50Jza5v

An interdisciplinary team of researchers from MIT and elsewhere is striving to create screen-reader-friendly data visualizations that offer a similarly rich experience. mitsha.re/W27M50Jp64a

Charting a safe course through a highly uncertain environment: A new technique can safely guide an autonomous robot without knowledge of its environmental conditions or the size, shape, or location of obstacles it might encounter. mitsha.re/Ik0y50JgzI2

Making data visualization more accessible for blind and low-vision individuals: Researchers have created prototypes that enable screen-reader users to quickly and easily navigate through multiple levels of information in an online chart. mitsha.re/W27M50Jp64a

No one likes sitting at a red light, or wasting fuel and producing emissions while idling. What if motorists could pace themselves to arrive when the light is green? A LIDS team’s new machine-learning approach could keep traffic flowing smoothly. mitsha.re/OZTC50J9Xg0
