Personalization features can make LLMs more agreeable

Personalization features can make LLMs more agreeable Many of the latest large language models (LLMs) are designed to remember details from past conversations or store user profiles, enabling these models to personalize responses.But researchers from MIT and Penn State University found that, over long conversations, such personalization ...

3D-printing platform rapidly produces complex electric machines

3D-printing platform rapidly produces complex electric machines A broken motor in an automated machine can bring production on a busy factory floor to a halt. If engineers can’t find a replacement part, they may have to order one from a distributor hundreds of miles away, leading to ...

New study unveils the mechanism behind “boomerang” earthquakes

New study unveils the mechanism behind “boomerang” earthquakes An earthquake typically sets off ruptures that ripple out from its underground origins. But on rare occasions, seismologists have observed quakes that reverse course, further shaking up areas that they passed through only seconds before. These “boomerang” earthquakes often occur ...

New AI model could cut the costs of developing protein drugs

New AI model could cut the costs of developing protein drugs Industrial yeasts are a powerhouse of protein production, used to manufacture vaccines, biopharmaceuticals, and other useful compounds. In a new study, MIT chemical engineers have harnessed artificial intelligence to optimize the development of new protein manufacturing processes, which could reduce ...

New J-PAL research and policy initiative to test and scale AI innovations to fight poverty

New J-PAL research and policy initiative to test and scale AI innovations to fight poverty The Abdul Latif Jameel Poverty Action Lab (J-PAL) at MIT has awarded funding to eight new research studies to understand how artificial intelligence innovations can be used in the fight against poverty through its new Project AI Evidence.The age of ...

Accelerating science with AI and simulations

Accelerating science with AI and simulations For more than a decade, MIT Associate Professor Rafael Gómez-Bombarelli has used artificial intelligence to create new materials. As the technology has expanded, so have his ambitions.Now, the newly tenured professor in materials science and engineering believes AI is poised ...

Using synthetic biology and AI to address global antimicrobial resistance threat

Using synthetic biology and AI to address global antimicrobial resistance threat James J. Collins, the Termeer Professor of Medical Engineering and Science at MIT and faculty co-lead of the Abdul Latif Jameel Clinic for Machine Learning in Health, is embarking on a multidisciplinary research project that applies synthetic biology and generative ...

AI algorithm enables tracking of vital white matter pathways

AI algorithm enables tracking of vital white matter pathways The signals that drive many of the brain and body’s most essential functions — consciousness, sleep, breathing, heart rate, and motion — course through bundles of “white matter” fibers in the brainstem, but imaging systems so far have been unable ...

Magnetic mixer improves 3D bioprinting

Magnetic mixer improves 3D bioprinting 3D bioprinting, in which living tissues are printed with cells mixed into soft hydrogels, or “bio-inks,” is widely used in the field of bioengineering for modeling or replacing the tissues in our bodies. The print quality and reproducibility of tissues, ...

3 Questions: Using AI to help Olympic skaters land a quint

3 Questions: Using AI to help Olympic skaters land a quint Olympic figure skating looks effortless. Athletes sail across the ice, then soar into the air, spinning like a top, before landing on a single blade just 4-5 millimeters wide. To help figure skaters land quadruple axels, Salchows, Lutzes, and maybe ...

A quick stretch switches this polymer’s capacity to transport heat

A quick stretch switches this polymer’s capacity to transport heat Most materials have an inherent capacity to handle heat. Plastic, for instance, is typically a poor thermal conductor, whereas materials like marble move heat more efficiently. If you were to place one hand on a marble countertop and the other ...

Study: Platforms that rank the latest LLMs can be unreliable

Study: Platforms that rank the latest LLMs can be unreliable A firm that wants to use a large language model (LLM) to summarize sales reports or triage customer inquiries can choose between hundreds of unique LLMs with dozens of model variations, each with slightly different performance.To narrow down the choice, ...

“This is science!” – MIT president talks about the importance of America’s research enterprise on... In a wide-ranging live conversation, MIT President Sally Kornbluth joined Jim Braude and Margery Eagan live in studio for GBH’s Boston Public Radio on Thursday, February 5. They talked about MIT, the pressures facing America’s research enterprise, the importance of science, ...

I’m walking here! A new model maps foot traffic in New York City

I’m walking here! A new model maps foot traffic in New York City Early in the 1969 film “Midnight Cowboy,” Dustin Hoffman, playing the character of Ratso Rizzo, crosses a Manhattan street and angrily bangs on the hood of an encroaching taxi. Hoffman’s line — “I’m walking here!” — has since been repeated ...

Some early life forms may have breathed oxygen well before it filled the atmosphere

Some early life forms may have breathed oxygen well before it filled the atmosphere Oxygen is a vital and constant presence on Earth today. But that hasn’t always been the case. It wasn’t until around 2.3 billion years ago that oxygen became a permanent fixture in the atmosphere, during a pivotal period known as ...

A satellite language network in the brain

A satellite language network in the brain The ability to use language to communicate is one of things that makes us human. At MIT’s McGovern Institute for Brain Research, scientists led by Evelina Fedorenko have defined an entire network of areas within the brain dedicated to this ...

Helping AI agents search to get the best results out of large language models

Helping AI agents search to get the best results out of large language models Whether you’re a scientist brainstorming research ideas or a CEO hoping to automate a task in human resources or finance, you’ll find that artificial intelligence tools are becoming the assistants you didn’t know you needed. In particular, many professionals are tapping ...

New vaccine platform promotes rare protective B cells

New vaccine platform promotes rare protective B cells A longstanding goal of immunotherapies and vaccine research is to induce antibodies in humans that neutralize deadly viruses such as HIV and influenza. Of particular interest are antibodies that are “broadly neutralizing,” meaning they can in principle eliminate multiple strains ...

3D-printed metamaterials that stretch and fail by design

3D-printed metamaterials that stretch and fail by design Metamaterials — materials whose properties are primarily dictated by their internal microstructure, and not their chemical makeup — have been redefining the engineering materials space for the last decade. To date, however, most metamaterials have been lightweight options designed for stiffness and strength.New ...

Terahertz microscope reveals the motion of superconducting electrons

Terahertz microscope reveals the motion of superconducting electrons You can tell a lot about a material based on the type of light you shine at it: Optical light illuminates a material’s surface, while X-rays reveal its internal structures and infrared captures a material’s radiating heat.Now, MIT physicists have ...
