Everything is a Brand

MIT engineers produce the world’s longest flexible...

December 20, 2021

Researchers have developed a rechargeable lithium-ion battery in the form of an ultra-long fiber that could be woven into fabrics. The battery could enable a wide variety of wearable electronic devices, and might even be used to make 3D-printed batteries in virtually any shape. The researchers envision new possibilities for self-powered communications, sensing, and computational devices that could be worn like ordinary clothing, as well as devices whose batteries could also double as structural parts. In a proof of...

Sensor based on quantum physics could detect...

December 20, 2021

A novel approach to testing for the presence of the virus that causes Covid-19 may lead to tests that are faster, less expensive, and potentially less prone to erroneous results than existing detection methods. Though the work, based on quantum effects, is still theoretical, these detectors could potentially be adapted to detect virtually any virus, the researchers say. The new approach is described in a paper published Thursday in the journal Nano Letters, by Changhao Li, an MIT doctoral...

Six humanities and arts faculty receive MIT...

December 17, 2021

The annual MIT SHASS Research Fund supports research in the Institute’s humanities, arts, and social science fields that shows promise of making an important contribution to the proposed area of activity. Congratulations to the six recipients for 2022: Dwai Banerjee, associate professor in the Program in Science, Technology, and Society, will use his award funding for work on the book project, “A Counter History of Computing in India.” Although India supplies cheap technological labor to the rest of the...

Expanding the conversation about sustainability

December 17, 2021

Stacy Godfreey-Igwe sat in her dorm room at MIT, staring frantically at her phone. An unprecedented snowstorm had hit her hometown of Richardson, Texas, and she was having difficulty contacting her family. She felt worried and frustrated, aware that nearby neighborhoods hadn’t lost power during the storm but that her family home had suffered significant damage. She finally got a hold of her parents, who had taken refuge in a nearby office building, but the experience left her shaken...

Adding depth to the popular discussion of...

December 17, 2021

In 2016, the state of North Carolina passed bill HB2, a controversial measure that barred most transgender people from using multiple-occupancy public restrooms. The legislation mandated that access for people was “based on their biological sex,” and relied on a particular and contested definition of gender, namely, “the condition of being male or female” as stated on a birth certificate. North Carolina did not seem to have a surfeit of restroom-use problems prior to 2016, and its law has...

Selective separation could help alleviate critical metals...

December 17, 2021

New processing methods developed by MIT researchers could help ease looming shortages of the essential metals that power everything from phones to automotive batteries, by making it easier to separate these rare metals from mining ores and recycled materials. Selective adjustments within a chemical process called sulfidation allowed professor of metallurgy Antoine Allanore and his graduate student Caspar Stinn to successfully target and separate rare metals, such as the cobalt in a lithium-ion battery, from mixed-metal materials. As they...

Characters for good, created by artificial intelligence

December 16, 2021

As it becomes easier to create hyper-realistic digital characters using artificial intelligence, much of the conversation around these tools has centered on misleading and potentially dangerous deepfake content. But the technology can also be used for positive purposes — to revive Albert Einstein to teach a physics class, talk through a career change with your older self, or anonymize people while preserving facial communication. To encourage the technology’s positive possibilities, MIT Media Lab researchers and their collaborators at the...

The power of economics to explain and...

December 16, 2021

Nobel Prize-winning economist Esther Duflo sympathizes with students who have no interest in her field. She was such a student herself — until an undergraduate research post gave her the chance to learn first-hand that economists address many of the major issues facing human and planetary well-being. “Most people have a wrong view of what economics is. They just see economists on television discussing what’s going to happen to the stock market,” says Duflo, the Abdul Latif Jameel Professor...

Q&A: Cathy Wu on developing algorithms to...

December 16, 2021

Cathy Wu is the Gilbert W. Winslow Assistant Professor of Civil and Environmental Engineering and a member of the MIT Institute for Data, Systems, and Society. As an undergraduate, Wu won MIT’s toughest robotics competition, and as a graduate student took the University of California at Berkeley’s first-ever course on deep reinforcement learning. Now back at MIT, she’s working to improve the flow of robots in Amazon warehouses under the Science Hub, a new collaboration between the tech giant...

Giving bug-like bots a boost

December 16, 2021

When it comes to robots, bigger isn’t always better. Someday, a swarm of insect-sized robots might pollinate a field of crops or search for survivors amid the rubble of a collapsed building. MIT researchers have demonstrated diminutive drones that can zip around with bug-like agility and resilience, which could eventually perform these tasks. The soft actuators that propel these microrobots are very durable, but they require much higher voltages than similarly-sized rigid actuators. The featherweight robots can’t carry the...

From counting blood cells to motion capture,...

December 15, 2021

Sensors and sensing systems — from devices that count white blood cells to technologies that monitor muscle coordination during rehabilitation — can positively impact medical research, scientists said at the 2021 SENSE.nano Symposium. The virtual event focused on how sensing technologies are enabling current medical studies and aiding translation of their findings to improve human health. Featuring leaders from research and industry, MIT-launched startup companies, and graduate students, the event was the fifth annual meeting organized by SENSE.nano. “In...

Nonsense can make sense to machine-learning models

December 15, 2021

For all that neural networks can accomplish, we still don’t really understand how they operate. Sure, we can program them to learn, but making sense of a machine’s decision-making process remains much like a fancy puzzle with a dizzying, complex pattern where plenty of integral pieces have yet to be fitted. If a model was trying to classify an image of said puzzle, for example, it could encounter well-known, but annoying adversarial attacks, or even more run-of-the-mill data or...

New visions for better transportation

December 15, 2021

We typically experience transportation problems from the ground up. Waiting for a delayed bus, packing ourselves into a subway car, or crawling along in traffic, it is common to see such systems struggling at close range. Yet sometimes transportation solutions come from a high-level, top-down approach. That was the theme of the final talk in MIT’s Mobility Forum series, delivered on Friday by MIT Professor Thomas Magnanti, which centered on applying to transportation the same overarching analytical framework used...

$7 million gift from the Shiv Nadar...

December 14, 2021

The MIT Department of Electrical Engineering and Computer Science (EECS) recently welcomed a $7 million gift from the Shiv Nadar Foundation. “Both Shiv Nadar and Roshni Nadar Malhotra share our commitment to excellence in education and in entrepreneurship, and the gifts we are celebrating today are extraordinary examples of that commitment,” said MIT President L. Rafael Reif in a celebratory Zoom gathering on Nov. 3, which was attended by Nadar, Malhotra, and top MIT leadership to celebrate the Shiv...

Harmonix keeps innovating, with lasting impact

December 14, 2021

Every holiday season, a popular new video game causes a disproportionate amount of hype, anticipation, and last-minute shopping. But few of those games offer an entirely new way to play. Even fewer have ripple effects that reach far beyond the gaming universe. When Guitar Hero was released in 2005, challenging players to hit notes to classic rock songs on guitar-like controllers, it grew from a holiday hit to a cultural phenomenon that taught a new generation to love rock...
