Strengthening trust in machine-learning models

March 28, 2023

Probabilistic machine learning methods are becoming increasingly powerful tools in data analysis, informing a range of critical decisions across disciplines and applications, from forecasting election results to predicting the impact of microloans on addressing poverty. This class of methods uses sophisticated concepts from probability theory to handle uncertainty in decision-making. But the math is only one piece of the puzzle in determining their accuracy and effectiveness. In a typical data analysis, researchers make many subjective choices, or potentially introduce...

New additives could turn concrete into an...

March 28, 2023

Despite the many advantages of concrete as a modern construction material, including its high strength, low cost, and ease of manufacture, its production currently accounts for approximately 8 percent of global carbon dioxide emissions. Recent discoveries by a team at MIT have revealed that introducing new materials into existing concrete manufacturing processes could significantly reduce this carbon footprint, without altering concrete’s bulk mechanical properties. The findings are published today in the journal PNAS Nexus, in a paper by MIT...

A portfolio that’s out of this world

March 27, 2023

At age 9, Ezinne Uzo-Okoro SM ’20, PhD ’22 was preoccupied with down-to-earth problems, such as devising an alternative to her father’s messy, paper Filofax organizer, and fixing the unreliable electric service plaguing her home of Owerri, Nigeria. Could she have imagined a path-breaking, 17-year career at NASA, followed by a position as the nation’s space policy expert? “Absolutely not,” says Uzo-Okoro. “I knew nothing about space — I wanted to be an inventor.” While she didn’t start as...

Festival of Learning 2023 underscores importance of...

March 27, 2023

During its first in-person gathering since 2020, MIT’s Festival of Learning 2023 explored how the learning sciences can inform the Institute on how to best support students. Co-sponsored by MIT Open Learning and the Office of the Vice Chancellor (OVC), this annual event celebrates teaching and learning innovations with MIT instructors, students, and staff. Bror Saxberg SM ’85, PhD ’89, founder of LearningForge LLC and former chief learning officer at Kaplan, Inc., was invited as keynote speaker, with opening...

Full immersion in health care for MIT...

March 27, 2023

Parents receiving an autism diagnosis for their child can be overwhelmed with emotions and questions. What does the diagnosis mean? How should they support their child? Who should they tell? For the past six years, MIT undergraduate students have worked to help individuals and families navigate those challenges by collaborating with Boston Medical Center’s Autism Program. Through the initiative, which is organized and funded by MIT’s PKG Public Service Center, students spend four weeks in January working full-time for...

A novel combination therapy for treating vancomycin-resistant...

March 24, 2023

Researchers have developed a novel combination therapy using the anticancer agent mitoxantrone (MTX), together with an antibiotic, vancomycin, for treating bacteria that are resistant to the vancomycin, which are also known as vancomycin-resistant Enterococcus faecalis or VRE. The therapy uniquely targets both VRE and the host, stimulating the host immune system to more effectively clear bacterial infections and accelerate infected wound healing. The work was led by scientists at the Antimicrobial Resistance (AMR) interdisciplinary research group at Singapore-MIT Alliance...

MIT Center for Real Estate advances climate...

March 23, 2023

Real estate investors are increasingly putting sustainability at the center of their decision-making processes, given the close association between climate risk and real estate assets, both of which are location-based. This growing emphasis comes at a time when the real estate industry is one of the biggest contributors to global warming; its embodied and operational carbon accounts for more than one-third of total carbon emissions. More stringent building decarbonization regulations are putting pressure on real estate owners and investors,...

New African and African diaspora studies major...

March 23, 2023

Commencement 2022 marked a milestone in MIT’s history, as Stacy Godfreey-Igwe ’22 became the first student to graduate in African and African diaspora studies (AADS). Godfreey-Igwe also majored in mechanical engineering and is now a fellow at the Science Technology Policy Institute in Washington. She recalls that while she did not initially intend to major in AADS, as the child of Nigerian immigrants she has long had a deep interest in her cultural and ethnic background. This interest, paired...

Giving refugees design education — and newfound...

March 23, 2023

They come by foot and by boat. Desperate, many bring nothing more than the clothes on their backs. They seek asylum and hope. Since 2015, more than a million refugees have flooded into Greece. Syrians, Afghanis, Iraqis, and Kurds, they’ve been uprooted from their home countries by violence and oppression. Political gridlock traps them in a country with longstanding economic woes and persistently high unemployment. The situation leaves them in overcrowded shelters, camps, slums — or unhoused entirely. Among...

Helping the cause of environmental resilience

March 22, 2023

Haruko Wainwright, the Norman C. Rasmussen Career Development Professor in Nuclear Science and Engineering (NSE) and assistant professor in civil and environmental engineering at MIT, grew up in rural Japan, where many nuclear facilities are located. She remembers worrying about the facilities as a child. Wainwright was only 6 at the time of the Chernobyl accident in 1986, but still recollects it vividly. Those early memories have contributed to Wainwright’s determination to research how technologies can mold environmental resilience...

Bob Metcalfe ’69 wins $1 million Turing...

March 22, 2023

Robert “Bob” Metcalfe ’69, an MIT Computer Science and Artificial Intelligence Laboratory (CSAIL) research affiliate and MIT Corporation life member emeritus, has been awarded the 2022 Association for Computing Machinery (ACM) A.M. Turing Award for his invention of Ethernet. Often referred to as the “Nobel Prize of computing,” the award comes with a $1 million prize provided by Google. Metcalfe, the founder of 3Com Corp., the company that designed, developed, and manufactured computer networking equipment and software, was cited...

Learning to grow machine-learning models

March 22, 2023

It’s no secret that OpenAI’s ChatGPT has some incredible capabilities — for instance, the chatbot can write poetry that resembles Shakespearean sonnets or debug code for a computer program. These abilities are made possible by the massive machine-learning model that ChatGPT is built upon. Researchers have found that when these types of models become large enough, extraordinary capabilities emerge. But bigger models also require more time and money to train. The training process involves showing hundreds of billions of...

MIT-led teams win National Science Foundation grants...

March 21, 2023

Three MIT-led teams are among 16 nationwide to receive funding awards to address sustainable materials for global challenges through the National Science Foundation’s Convergence Accelerator program. Launched in 2019, the program targets solutions to especially compelling societal or scientific challenges at an accelerated pace, by incorporating a multidisciplinary research approach. “Solutions for today’s national-scale societal challenges are hard to solve within a single discipline. Instead, these challenges require convergence to merge ideas, approaches, and technologies from a wide range...

Fiber “barcodes” can make clothing labels that...

March 21, 2023

In the United States, an estimated 15 million tons of textiles end up in landfills or are burned every year. This waste, amounting to 85 percent of the textiles produced in a year, is a growing environmental problem. In 2022, Massachusetts became the first state to enact a law banning the disposal of textiles in the trash, aiming to up recycling percentages. But recycling textiles isn’t always easy. Those that can’t be resold as-is are sent to facilities to...
