When MIT’s interdisciplinary NEET program is a...

December 17, 2024

At an early age, Katie Spivakovsky learned to study the world from different angles. Dinner-table conversations at her family’s home in Menlo Park, California, often leaned toward topics like the Maillard reaction — the chemistry behind food browning — or the fascinating mysteries of prime numbers. Spivakovsky’s parents, one of whom studied physical chemistry and the other statistics, fostered a love of knowledge that crossed disciplines. In high school, Spivakovsky explored it all, from classical literature to computer science....

3 Questions: Tracking MIT graduates’ career trajectories

December 17, 2024

In a fall letter to MIT alumni, President Sally Kornbluth wrote: “he world has never been more ready to reward our graduates for what they know — and know how to do.” During her tenure leading MIT Career Advising and Professional Development (CAPD), Deborah Liverman has seen firsthand how — and how well — MIT undergraduate and graduate students leverage their education to make an impact around the globe in academia, industry, entrepreneurship, medicine, government and nonprofits, and other...

MIT spinout Commonwealth Fusion Systems unveils plans...

December 17, 2024

America is one step closer to tapping into a new and potentially limitless clean energy source today, with the announcement from MIT spinout Commonwealth Fusion Systems (CFS) that it plans to build the world’s first grid-scale fusion power plant in Chesterfield County, Virginia. The announcement is the latest milestone for the company, which has made groundbreaking progress toward harnessing fusion — the reaction that powers the sun — since its founders first conceived of their approach in an MIT...

MIT researchers introduce Boltz-1, a fully open-source...

December 17, 2024

MIT scientists have released a powerful, open-source AI model, called Boltz-1, that could significantly accelerate biomedical research and drug development. Developed by a team of researchers in the MIT Jameel Clinic for Machine Learning in Health, Boltz-1 is the first fully open-source model that achieves state-of-the-art performance at the level of AlphaFold3, the model from Google DeepMind that predicts the 3D structures of proteins and other biological molecules. MIT graduate students Jeremy Wohlwend and Gabriele Corso were the lead developers...

Aurora mapping across North America

December 16, 2024

As seen across North America at sometimes surprisingly low latitudes, brilliant auroral displays provide evidence of solar activity in the night sky. More is going on than the familiar visible light shows during these events, though: When aurora appear, the Earth’s ionosphere is experiencing an increase in ionization and total electron content (TEC) due to energetic electrons and ions precipitating into the ionosphere. One extreme auroral event earlier this year (May 10–11) was the Gannon geomagnetic “superstorm,” named in honor...

A new method to detect dehydration in...

December 16, 2024

Have you ever wondered if your plants were dry and dehydrated, or if you’re not watering them enough? Farmers and green-fingered enthusiasts alike may soon have a way to find this out in real-time. Over the past decade, researchers have been working on sensors to detect a wide range of chemical compounds, and a critical bottleneck has been developing sensors that can be used within living biological systems. This is all set to change with new sensors by the Singapore-MIT...

Study reveals AI chatbots can detect race,...

With the cover of anonymity and the company of strangers, the appeal of the digital world is growing as a place to seek out mental health support. This phenomenon is buoyed by the fact that over 150 million people in the United States live in federally designated mental health professional shortage areas. “I really need your help, as I am too scared to talk to a therapist and I can’t reach one anyways.” “Am I overreacting, getting hurt about husband...

New climate chemistry model finds “non-negligible” impacts...

December 16, 2024

As the world looks for ways to stop climate change, much discussion focuses on using hydrogen instead of fossil fuels, which emit climate-warming greenhouse gases (GHGs) when they’re burned. The idea is appealing. Burning hydrogen doesn’t emit GHGs to the atmosphere, and hydrogen is well-suited for a variety of uses, notably as a replacement for natural gas in industrial processes, power generation, and home heating. But while burning hydrogen won’t emit GHGs, any hydrogen that’s leaked from pipelines or...

MIT affiliates named 2024 Schmidt Futures AI2050...

December 13, 2024

Five MIT faculty members and two additional alumni were recently named to the 2024 cohort of AI2050 Fellows. The honor is announced annually by Schmidt Futures, Eric and Wendy Schmidt’s philanthropic initiative that aims to accelerate scientific innovation. Conceived and co-chaired by Eric Schmidt and James Manyika, AI2050 is a philanthropic initiative aimed at helping to solve hard problems in AI. Within their research, each fellow will contend with the central motivating question of AI2050: “It’s 2050. AI has turned...

Artifacts from a half-century of cancer research

December 13, 2024

Throughout 2024, MIT’s Koch Institute for Integrative Cancer Research has celebrated 50 years of MIT’s cancer research program and the individuals who have shaped its journey. In honor of this milestone anniversary year, on Nov. 19 the Koch Institute celebrated the opening of a new exhibition: Object Lessons: Celebrating 50 Years of Cancer Research at MIT in 10 Items. Object Lessons invites the public to explore significant artifacts — from one of the earliest PCR machines, developed in the...

Teaching a robot its limits, to complete...

December 12, 2024

If someone advises you to “know your limits,” they’re likely suggesting you do things like exercise in moderation. To a robot, though, the motto represents learning constraints, or limitations of a specific task within the machine’s environment, to do chores safely and correctly. For instance, imagine asking a robot to clean your kitchen when it doesn’t understand the physics of its surroundings. How can the machine generate a practical multistep plan to ensure the room is spotless? Large language...

Students strive for “Balance!” in a lively...

December 12, 2024

On an otherwise dark and rainy Monday night, attendees packed Kresge Auditorium for a lively and colorful celebration of student product designs, as part of the final presentations for MIT’s popular class 2.009 (Product Engineering Processes). With “Balance!” as its theme, the vibrant show attracted hundreds of attendees along with thousands more who tuned in online to see students pitch their products. The presentations were the culmination of a semester’s worth of work in which six student teams were...

Enabling a circular economy in the built...

December 11, 2024

The amount of waste generated by the construction sector underscores an urgent need for embracing circularity — a sustainable model that aims to minimize waste and maximize material efficiency through recovery and reuse — in the built environment: 600 million tons of construction and demolition waste was produced in the United States alone in 2018, with 820 million tons reported in the European Union, and an excess of 2 billion tons annually in China. This significant resource loss embedded in our...

Noninvasive imaging method can penetrate deeper into...

December 11, 2024

Metabolic imaging is a noninvasive method that enables clinicians and scientists to study living cells using laser light, which can help them assess disease progression and treatment responses. But light scatters when it shines into biological tissue, limiting how deep it can penetrate and hampering the resolution of captured images. Now, MIT researchers have developed a new technique that more than doubles the usual depth limit of metabolic imaging. Their method also boosts imaging speeds, yielding richer and more...

Researchers reduce bias in AI models while...

December 11, 2024

Machine-learning models can fail when they try to make predictions for individuals who were underrepresented in the datasets they were trained on. For instance, a model that predicts the best treatment option for someone with a chronic disease may be trained using a dataset that contains mostly male patients. That model might make incorrect predictions for female patients when deployed in a hospital. To improve outcomes, engineers can try balancing the training dataset by removing data points until all...
