Q&A: Claire Walsh on how J-PAL’s King...
The King Climate Action Initiative (K-CAI) is the flagship climate change program of the Abdul Latif Jameel Poverty Action Lab (J-PAL), which innovates, tests, and scales solutions at the nexus of climate change and poverty alleviation, together with policy partners worldwide. Claire Walsh is the associate director of policy at J-PAL Global at MIT. She is also the project director of K-CAI. Here, Walsh talks about the work of K-CAI since its launch in 2020, and describes the ways...

Plant sensors could act as an early...
Using a pair of sensors made from carbon nanotubes, researchers from MIT and the Singapore-MIT Alliance for Research and Technology (SMART) have discovered signals that reveal when plans are experiencing stresses such as heat, light, or attack from insects or bacteria. The sensors detect two signaling molecules that plants use to coordinate their response to stress: hydrogen peroxide and salicylic acid (a molecule similar to aspirin). The researchers found that plants produce these molecules at different timepoints for each...

3 Questions: Enhancing last-mile logistics with machine...
Across the country, hundreds of thousands of drivers deliver packages and parcels to customers and companies each day, with many click-to-door times averaging only a few days. Coordinating a supply chain feat of this magnitude in a predictable and timely way is a longstanding problem of operations research, where researchers have been working to optimize the last leg of delivery routes. This is because the last phase of the process is often the costliest due to inefficiencies like long...

Women in STEM — A celebration of...
What better way to commemorate Women’s History Month and International Women’s Day than to give  three of the world’s most accomplished scientists an opportunity to talk about their careers? On March 7, MindHandHeart invited professors Paula Hammond, Ann Graybiel, and Sangeeta Bhatia to share their career journeys, from the progress they have witnessed to the challenges they have faced as women in STEM. Their conversation was moderated by Mary Fuller, chair of the faculty and professor of literature.  Hammond,...

A blueprint for making quantum computers easier...
When MIT professor and now Computer Science and Artificial Intelligence Laboratory (CSAIL) member Peter Shor first demonstrated the potential of quantum computers to solve problems faster than classical ones, he inspired scientists to imagine countless possibilities for the emerging technology. Thirty years later, though, the quantum edge remains a peak not yet reached. Unfortunately, the technology of quantum computing isn’t fully operational yet. One major challenge lies in translating quantum algorithms from abstract mathematical concepts into concrete code that...

“Nanostitches” enable lighter and tougher composite materials
To save on fuel and reduce aircraft emissions, engineers are looking to build lighter, stronger airplanes out of advanced composites. These engineered materials are made from high-performance fibers that are embedded in polymer sheets. The sheets can be stacked and pressed into one multilayered material and made into extremely lightweight and durable structures. But composite materials have one main vulnerability: the space between layers, which is typically filled with polymer “glue” to bond the layers together. In the event...

MIT tops among single-campus universities in US...
In an era defined by unprecedented challenges and opportunities, MIT remains at the forefront of pioneering research and innovation. The Institute’s relentless pursuit of knowledge has once again been recognized, with MIT securing 343 utility patents issued by the United States Patent and Trademark Office in 2023. This marks the 10th consecutive year that the National Academy of Inventors has both ranked worldwide colleges for number of U.S. patents issued and recognized MIT as the top single-campus university for...

A new way to detect radiation involving...
The radiation detectors used today for applications like inspecting cargo ships for smuggled nuclear materials are expensive and cannot operate in harsh environments, among other disadvantages. Now, in work funded largely by the U.S. Department of Homeland Security with early support from the U.S. Department of Energy, MIT engineers have demonstrated a fundamentally new way to detect radiation that could allow much cheaper detectors and a plethora of new applications. They are working with Radiation Monitoring Devices, a company...

A crossroads for computing at MIT
On Vassar Street, in the heart of MIT’s campus, the MIT Stephen A. Schwarzman College of Computing recently opened the doors to its new headquarters in Building 45. The building’s central location and welcoming design will help form a new cluster of connectivity at MIT and enable the space to have a multifaceted role.  “The college has a broad mandate for computing across MIT,” says Daniel Huttenlocher, dean of the MIT Schwarzman College of Computing and the Henry Ellis...

Growing our donated organ supply
For those in need of one, an organ transplant is a matter of life and death.  Every year, the medical procedure gives thousands of people with advanced or end-stage diseases extended life. This “second chance” is heavily dependent on the availability, compatibility, and proximity of a precious resource that can’t be simply bought, grown, or manufactured — at least not yet. Instead, organs must be given — cut from one body and implanted into another. And because living organ...

New AI method captures uncertainty in medical...
In biomedicine, segmentation involves annotating pixels from an important structure in a medical image, like an organ or cell. Artificial intelligence models can help clinicians by highlighting pixels that may show signs of a certain disease or anomaly. However, these models typically only provide one answer, while the problem of medical image segmentation is often far from black and white. Five expert human annotators might provide five different segmentations, perhaps disagreeing on the existence or extent of the borders...

Improving drug development with a vast map...
The human immune system is a network made up of trillions of cells that are constantly circulating throughout the body. The cellular network orchestrates interactions with every organ and tissue to carry out an impossibly long list of functions that scientists are still working to understand. All that complexity limits our ability to predict which patients will respond to treatments and which ones might suffer debilitating side effects. The issue often leads pharmaceutical companies to stop developing drugs that...

MIT-Mexico Program fosters cross-border collaboration
Favianna Colón Irizarry spent last summer at Tecnológico de Monterrey, working alongside Mexican biotechnology researchers to develop a biodegradable coating that prolongs the shelf life of local foods. Assisting in this and other innovative projects at one of Mexico’s top research institutions was the opportunity of a lifetime, for sure. But, for Colón Irizarry, it’s the tapestry of experiences that accompanied her MIT-Mexico internship that will always resonate. “From my internship, I gleaned a vital lesson: Cultural proficiency is...
