How to build AI scaling laws for...
When researchers are building large language models (LLMs), they aim to maximize performance under a particular computational and financial budget. Since training a model can amount to millions of dollars, developers need to be judicious with cost-impacting decisions about, for instance, the model architecture, optimizers, and training datasets before committing to a model. To anticipate the quality and accuracy of a large model’s predictions, practitioners often turn to scaling laws: using smaller, cheaper models to try to approximate the...

Climate Action Learning Lab helps state and...
This spring, J-PAL North America — a regional office of MIT’s Abdul Latif Jameel Poverty Action Lab (J-PAL) — launched its first ever Learning Lab, centered on climate action. The Learning Lab convened a cohort of government leaders who are enacting a broad range of policies and programs to support the transition to a low-carbon economy. Through the Learning Lab, participants explored how to embed randomized evaluation into promising solutions to determine how to maximize changes in behavior — a...

How MIT’s Steel Research Group led to...
Traditionally, developing new materials for cutting-edge applications — such as SpaceX’s Raptor engine — has taken a decade or more. But thanks to a breakthrough technology pioneered by an MIT research group now celebrating its 40th year, a key material for the Raptor was delivered in just a few years. The same innovation has accelerated the development of high-performance materials for the Apple Watch, U.S. Air Force jets, and Formula One race cars. The MIT Steel Research Group (SRG)...

Lidar helps gas industry find methane leaks...
Each year, the U.S. energy industry loses an estimated 3 percent of its natural gas production, valued at $1 billion in revenue, to leaky infrastructure. Escaping invisibly into the air, these methane gas plumes can now be detected, imaged, and measured using a specialized lidar flown on small aircraft. This lidar is a product of Bridger Photonics, a leading methane-sensing company based in Bozeman, Montana. MIT Lincoln Laboratory developed the lidar’s optical-power amplifier, a key component of the system,...

MIT launches Day of Design to bring...
A new MIT initiative known as Day of Design offers free, open-source, hands-on design activities for all classrooms, in addition to professional development opportunities and signature events. The material engages pK-12 learners in the skills they need to solve complex open-ended problems while also considering user, social, and environmental needs. Inspired by Day of AI and Day of Climate, it is a new collaborative effort by the MIT Morningside Academy for Design (MAD) and the WPS Institute, with support from the MIT pK-12 Initiative....

New RNA tool to advance cancer and...
Researchers at the Antimicrobial Resistance (AMR) interdisciplinary research group of the Singapore-MIT Alliance for Research and Technology (SMART), MIT’s research enterprise in Singapore, have developed a powerful tool capable of scanning thousands of biological samples to detect transfer ribonucleic acid (tRNA) modifications — tiny chemical changes to RNA molecules that help control how cells grow, adapt to stress, and respond to diseases such as cancer and antibiotic‑resistant infections. This tool opens up new possibilities for science, health care, and industry —...

MIT software tool turns everyday objects into...
Whether you’re an artist, advertising specialist, or just looking to spruce up your home, turning everyday objects into dynamic displays is a great way to make them more visually engaging. For example, you could turn a kids’ book into a handheld cartoon of sorts, making the reading experience more immersive and memorable for a child. But now, thanks to MIT researchers, it’s also possible to make dynamic displays without using electronics, using barrier-grid animations (or scanimations), which use printed materials instead....

DoE selects MIT to establish a Center...
The U.S. Department of Energy’s National Nuclear Security Administration (DoE/NNSA) recently announced that it has selected MIT to establish a new research center dedicated to advancing the predictive simulation of extreme environments, such as those encountered in hypersonic flight and atmospheric re-entry. The center will be part of the fourth phase of NNSA’s Predictive Science Academic Alliance Program (PSAAP-IV), which supports frontier research advancing the predictive capabilities of high-performance computing for open science and engineering applications relevant to national security mission...

The following article is adapted from a press release issued by the Laser Interferometer Gravitational-wave Observatory (LIGO) Laboratory. LIGO is funded by the National Science Foundation and operated by Caltech and MIT, which conceived and built the project. On Sept. 14, 2015, a signal arrived on Earth, carrying information about a pair of remote black holes that had spiraled together and merged. The signal had traveled about 1.3 billion years to reach us at the speed of light —...

Study finds cell memory can be more...
When cells are healthy, we don’t expect them to suddenly change cell types. A skin cell on your hand won’t naturally morph into a brain cell, and vice versa. That’s thanks to epigenetic memory, which enables the expression of various genes to “lock in” throughout a cell’s lifetime. Failure of this memory can lead to diseases, such as cancer. Traditionally, scientists have thought that epigenetic memory locks genes either “on” or “off” — either fully activated or fully repressed,...

“Bottlebrush” particles deliver big chemotherapy payloads directly...
Using tiny particles shaped like bottlebrushes, MIT chemists have found a way to deliver a large range of chemotherapy drugs directly to tumor cells. To guide them to the right location, each particle contains an antibody that targets a specific tumor protein. This antibody is tethered to bottlebrush-shaped polymer chains carrying dozens or hundreds of drug molecules — a much larger payload than can be delivered by any existing antibody-drug conjugates. In mouse models of breast and ovarian cancer,...
