Remembering David Baltimore, influential biologist and founding...
The Whitehead Institute for Biomedical Research fondly remembers its founding director, David Baltimore, a former MIT Institute Professor and Nobel laureate who died Sept. 6 at age 87. With discovery after discovery, Baltimore brought to light key features of biology with direct implications for human health. His work at MIT earned him a share of the 1975 Nobel Prize in Physiology or Medicine (along with Howard Temin and Renato Dulbecco) for discovering reverse transcriptase and identifying retroviruses, which use...

Alzheimer’s erodes brain cells’ control of gene...
Most people recognize Alzheimer’s disease from its devastating symptoms such as memory loss, while new drugs target pathological aspects of disease manifestations, such as plaques of amyloid proteins. Now, a sweeping new open-access study in the Sept. 4 edition of Cell by MIT researchers shows the importance of understanding the disease as a battle over how well brain cells control the expression of their genes. The study paints a high-resolution picture of a desperate struggle to maintain healthy gene...

AI and machine learning for engineering design
Artificial intelligence optimization offers a host of benefits for mechanical engineers, including faster and more accurate designs and simulations, improved efficiency, reduced development costs through process automation, and enhanced predictive maintenance and quality control. “When people think about mechanical engineering, they’re thinking about basic mechanical tools like hammers and … hardware like cars, robots, cranes, but mechanical engineering is very broad,” says Faez Ahmed, the Doherty Chair in Ocean Utilization and associate professor of mechanical engineering at MIT. “Within mechanical engineering, machine...

A comprehensive cellular-resolution map of brain activity
The first comprehensive map of mouse brain activity has been unveiled by a large international collaboration of neuroscientists.  Researchers from the International Brain Laboratory (IBL), including MIT neuroscientist Ila Fiete, published their open-access findings today in two papers in Nature, revealing insights into how decision-making unfolds across the entire brain in mice at single-cell resolution. This brain-wide activity map challenges the traditional hierarchical view of information processing in the brain and shows that decision-making is distributed across many regions...

A greener way to 3D print stronger...
3D printing has come a long way since its invention in 1983 by Chuck Hull, who pioneered stereolithography, a technique that solidifies liquid resin into solid objects using ultraviolet lasers. Over the decades, 3D printers have evolved from experimental curiosities into tools capable of producing everything from custom prosthetics to complex food designs, architectural models, and even functioning human organs.  But as the technology matures, its environmental footprint has become increasingly difficult to set aside. The vast majority of...

A new generative AI approach to predicting...
Many attempts have been made to harness the power of new artificial intelligence and large language models (LLMs) to try to predict the outcomes of new chemical reactions. These have had limited success, in part because until now they have not been grounded in an understanding of fundamental physical principles, such as the laws of conservation of mass. Now, a team of researchers at MIT has come up with a way of incorporating these physical constraints on a reaction...

3 Questions: On biology and medicine’s “data...
Caroline Uhler is an Andrew (1956) and Erna Viterbi Professor of Engineering at MIT; a professor of electrical engineering and computer science in the Institute for Data, Science, and Society (IDSS); and director of the Eric and Wendy Schmidt Center at the Broad Institute of MIT and Harvard, where she is also a core institute and scientific leadership team member.  Uhler is interested in all the methods by which scientists can uncover causality in biological systems, ranging from causal discovery on...

New gift expands mental illness studies at...
One in every eight people — 970 million globally — live with mental illness, according to the World Health Organization, with depression and anxiety being the most common mental health conditions worldwide. Existing therapies for complex psychiatric disorders like depression, anxiety, and schizophrenia have limitations, and federal funding to address these shortcomings is growing increasingly uncertain. Patricia and James Poitras ’63 have committed $8 million to the Poitras Center for Psychiatric Disorders Research to launch pioneering research initiatives aimed...

New particle detector passes the “standard candle”...
A new and powerful particle detector just passed a critical test in its goal to decipher the ingredients of the early universe. The sPHENIX detector is the newest experiment at Brookhaven National Laboratory’s Relativistic Heavy Ion Collider (RHIC) and is designed to precisely measure products of high-speed particle collisions. From the aftermath, scientists hope to reconstruct the properties of quark-gluon plasma (QGP) — a white-hot soup of subatomic particles known as quarks and gluons that is thought to have...

Advancing career and academic ambitions with MITx...
For a long time, Satik Movsesyan envisioned a future of working in finance and also pursuing a full-time master’s degree program at the MIT Sloan School of Management. She says the MITx MicroMasters Program in Finance provides her with the ideal opportunity to directly enhance her career with courses developed and delivered by MIT Sloan faculty. Movsesyan first began actively pursuing ways to connect with the MIT community as a first-year student in her undergraduate program at the American University...

Understanding shocks to welfare systems
In an unhappy coincidence, the Covid-19 pandemic and Angie Jo’s doctoral studies in political science both began in 2019. Paradoxically, this global catastrophe helped define her primary research thrust. As countries reacted with unprecedented fiscal measures to protect their citizens from economic collapse, Jo MCP ’19 discerned striking patterns among these interventions: Nations typically seen as the least generous on social welfare were suddenly deploying the most dramatic emergency responses. “I wanted to understand why countries like the U.S.,...

MIT researchers develop AI tool to improve...
Every year, global health experts are faced with a high-stakes decision: Which influenza strains should go into the next seasonal vaccine? The choice must be made months in advance, long before flu season even begins, and it can often feel like a race against the clock. If the selected strains match those that circulate, the vaccine will likely be highly effective. But if the prediction is off, protection can drop significantly, leading to (potentially preventable) illness and strain on...

Why countries trade with each other while...
In World War II, Britain was fighting for its survival against German aerial bombardment. Yet Britain was importing dyes from Germany at the same time. This sounds curious, to put it mildly. How can two countries at war with each other also be trading goods? Examples of this abound, actually. Britain also traded with its enemies for almost all of World War I. India and Pakistan conducted trade with each other during the First Kashmir War, from 1947 to...

Locally produced proteins help mitochondria function
Our cells produce a variety of proteins, each with a specific role that, in many cases, means that they need to be in a particular part of the cell where that role is needed. One of the ways that cells ensure certain proteins end up in the right location at the right time is through localized translation, a process that ensures that proteins are made — or translated — close to where they will be needed. MIT professor of...

The MIT School of Humanities, Arts, and Social Sciences announced leadership changes in three of its academic units for the 2025-26 academic year. “We have an excellent cohort of leaders coming in,” says Agustín Rayo, the Kenan Sahin Dean of the School of Humanities, Arts, and Social Sciences. “I very much look forward to working with them and welcoming them into the school’s leadership team.” Sandy Alexandre will serve as head of MIT Literature. Alexandre is an associate professor...
