New research collaboration aims to tackle global...

November 8, 2022

At a signing ceremony last week, leaders from the MIT School of Architecture and Planning, the MIT Morningside Academy for Design (MAD) and the Hasso Plattner Institute (HPI) announced the Hasso Plattner Institute-MIT Research Program on Designing for Sustainability. This research collaboration, funded by the Hasso Plattner Foundation, is an eight-year program to drive joint scientific research at both institutes in sustainable design, innovation, and digital technologies, as well as in translating research results into practice. Through this engagement,...

Urbanization: No fast lane to transformation

November 8, 2022

Accra, Ghana, “is a city I’ve come to know as well as any place in the U.S,” says Associate Professor Noah Nathan, who has conducted research there over the past 15 years. The booming capital of 4 million is an ideal laboratory for investigating the rapid urbanization of nations in Africa and beyond, believes Nathan, who joined the MIT Department of Political Science in July. “Accra is vibrant and exciting, with gleaming glass office buildings, shopping centers, and an...

A whole new world of learning via...

November 7, 2022

Like millions of others during the global Covid-19 lockdowns, Emmanuel Kasigazi, an entrepreneur from Uganda, turned to YouTube to pass the time. But he wasn’t following an influencer or watching music videos. A lifelong learner, Kasigazi was scouring the video-sharing platform for educational resources. Since 2013, when he got his first smartphone, Kasigazi has been charting his own learning journey through YouTube, educating himself on subjects as diverse as psychology and artificial intelligence. And it was while searching for...

UpNano joins MIT.nano Consortium

November 7, 2022

MIT.nano has announced that UpNano US Inc., a company that manufactures and supplies high-precision and high-resolution 3D printing instruments for academia and industry, has joined the MIT.nano Consortium. This engagement, initially planned for two years, will include locating one of UpNano’s NanoOne 1000 instruments in MIT.nano. “We’re thrilled to welcome UpNano to the MIT.nano Consortium,” says Vladimir Bulović, the founding faculty director of MIT.nano and the Fariborz Maseeh (1990) Professor of Emerging Technology. “Not only is UpNano’s 3D printing...

Video on the record

November 4, 2022

Among the Pulitzer Prizes awarded in 2021 was a citation for a teenager who changed history with her cell phone. The Pulitzer committee acknowledged Darnella Frazier “for courageously recording the murder of George Floyd, a video that spurred protests against police brutality around the world, highlighting the crucial role of citizens in journalists’ quest for truth and justice.” Frazier’s act of witness received uncommon recognition, but it exists on a continuum with countless other visual documentations of injustice leveraged...

Professor Emeritus Louis Braida, speech and hearing...

November 4, 2022

Louis Braida, the Henry Ellis Warren (1894) Professor Emeritus in the MIT Department of Electrical Engineering and Computer Science (EECS), died Sept. 2. He was 79. Braida was a principal researcher in the Research Laboratory of Electronics, and a faculty member in the Harvard-MIT Program in Health Sciences and Technology (HST), which is housed in the Institute for Medical Engineering and Science (IMES) at MIT. Born in the Bronx to Louis Braida and Elvina Tonelli Braida, Braida received a...

MIT engineers develop a low-cost terahertz camera

November 4, 2022

Terahertz radiation, whose wavelengths lie between those of microwaves and visible light, can penetrate many nonmetallic materials and detect signatures of certain molecules. These handy qualities could lend themselves to a wide array of applications, including airport security scanning, industrial quality control, astrophysical observations, nondestructive characterization of materials, and wireless communications with higher bandwidth than current cellphone bands. However, designing devices to detect and make images from terahertz waves has been challenging, and most existing terahertz devices are expensive,...

Facing reality, however painful it may be

November 4, 2022

Let’s acknowledge it: Life is tough. Most people struggle to make a secure living, stay healthy, and care for family members. On a larger scale, climate change keeps unfolding, Ukraine is under attack, authoritarianism is gaining ground around the world, and a pandemic has disrupted society. How are we supposed to feel good amid all this? Well, you might not feel good. But you can still live a good life. That is a central message of “Life Is Hard,”...

New materials could enable longer-lasting implantable batteries

November 4, 2022

For the last few decades, battery research has largely focused on rechargeable lithium-ion batteries, which are used in everything from electric cars to portable electronics and have improved dramatically in terms of affordability and capacity. But nonrechargeable batteries have seen little improvement during that time, despite their crucial role in many important uses such as implantable medical devices like pacemakers. Now, researchers at MIT have come up with a way to improve the energy density of these nonrechargeable, or...

Ocean microbes get their diet through a...

November 3, 2022

One of the smallest and mightiest organisms on the planet is a plant-like bacterium known to marine biologists as Prochlorococcus. The green-tinted microbe measures less than a micron across, and its populations suffuse through the upper layers of the ocean, where a single teaspoon of seawater can hold millions of the tiny organisms. Prochlorococcus grows through photosynthesis, using sunlight to convert the atmosphere’s carbon dioxide into organic carbon molecules. The microbe is responsible for 5 percent of the world’s...

Can your phone tell if a bridge...

November 3, 2022

Want to know if the Golden Gate Bridge is holding up well? There could be an app for that. A new study involving MIT researchers shows that mobile phones placed in vehicles, equipped with special software, can collect useful structural integrity data while crossing bridges. In so doing, they could become a less expensive alternative to sets of sensors attached to bridges themselves. “The core finding is that information about structural health of bridges can be extracted from smartphone-collected...

The “last mile” from credentials to employment

November 3, 2022

Academic digital credentials — the cryptographically verifiable assertion that an individual holds a degree, certificate, or other credential — have been available for the better part of a decade. Yet despite the potential value of these data-rich, transportable credentials to graduates, employers, and academic institutions, digital credentials have by no means become the standard in presenting or verifying skills and qualifications. A new report from the Digital Credentials Consortium (DCC), housed at MIT Open Learning, explores this gap between...

In machine learning, synthetic data can offer...

November 3, 2022

Teaching a machine to recognize human actions has many potential applications, such as automatically detecting workers who fall at a construction site or enabling a smart home robot to interpret a user’s gestures. To do this, researchers train machine-learning models using vast datasets of video clips that show humans performing actions. However, not only is it expensive and laborious to gather and label millions or billions of videos, but the clips often contain sensitive information, like people’s faces or...

Nanosensors target enzymes to monitor and study...

November 2, 2022

Cancer is characterized by a number of key biological processes known as the “hallmarks of cancer,” which remodel cells and their immediate environment so that tumors can form, grow, and thrive. Many of these changes are mediated by specific genes and proteins, working in tandem with other cellular processes, but the specifics vary from cancer type to cancer type, and even from patient to patient. Sensitive tools for measuring protein or gene expression, even on the single cell level,...

Methane research takes on new urgency at...

November 2, 2022

One of the most notable climate change provisions in the 2022 Inflation Reduction Act is the first U.S. federal tax on a greenhouse gas (GHG). That the fee targets methane (CH4), rather than carbon dioxide (CO2), emissions is indicative of the urgency the scientific community has placed on reducing this short-lived but powerful gas. Methane persists in the air about 12 years — compared to more than 1,000 years for CO2 — yet it immediately causes about 120 times more...
