Making genetic prediction models more inclusive

October 26, 2023

While any two human genomes are about 99.9 percent identical, genetic variation in the remaining 0.1 percent plays an important role in shaping human diversity, including a person’s risk for developing certain diseases. Measuring the cumulative effect of these small genetic differences can provide an estimate of an individual’s genetic risk for a particular disease or their likelihood of having a particular trait. However, the majority of models used to generate these “polygenic scores” are based on studies done...

Shape-shifting fiber can produce morphing fabrics

October 26, 2023

Instead of needing a coat for each season, imagine having a jacket that would dynamically change shape so it becomes more insulating to keep you warm as the temperature drops. A programmable, actuating fiber developed by an interdisciplinary team of MIT researchers could someday make this vision a reality. Known as FibeRobo, the fiber contracts in response to an increase in temperature, then self-reverses when the temperature decreases, without any embedded sensors or other hard components.

Eight high school teams named Lemelson-MIT InvenTeams...

October 25, 2023

The Lemelson-MIT Program has announced the 2023-24 InvenTeams, eight teams of high school students, teachers, and mentors from across the country who each will receive $7,500 in grant funding and other support to build a technological invention to solve a problem of their own choosing. The students’ inventions are inspired by real-world problems they identified in their local communities. Meet the 2023–24 InvenTeams The InvenTeams were selected by a panel consisting of university professors, inventors, entrepreneurs, industry professionals, and...

Bright flash leads astronomers to a heavy-metal...

October 25, 2023

An extraordinary burst of high-energy light in the sky has pointed astronomers to a pair of metal-forging neutron stars 900 million light years from Earth. In a study appearing today in Nature, an international team of astronomers, including scientists at MIT, reports the detection of an extremely bright gamma-ray burst (GRB), which is the most powerful type of explosion known in the universe. This particular GRB is the second-brightest so far detected, and the astronomers subsequently traced the burst’s...

Smart irrigation technology covers “more crop per...

October 25, 2023

In agriculture today, robots and drones can monitor fields, temperature and moisture sensors can be automated to meet crop needs, and a host of other systems and devices make farms more efficient, resource-conscious, and profitable. The use of precision agriculture, as these technologies are collectively known, offers significant advantages. However, because the technology can be costly, it remains out of reach for the majority of the world’s farmers. “Many of the poor around the world are small, subsistence farmers,”...

Mobilizing creative learning with OctoStudio

October 24, 2023

A group of schoolchildren in Chile walk on a hillside, taking photos of plants and animals with mobile devices. They later integrate the photos into animated stories about the local environment. Two friends in Uganda create an interactive game with an animated chicken that moves across the screen as you tilt the phone — and speaks aloud in Swahili when it finds water. A girl collaborates with her mom to make an animated birthday card for her grandmother, including family...

Q&A: Magnifying research impact with policymakers

October 23, 2023

The MIT Policy Lab at the Center for International Studies works with researchers across the Institute to develop and enhance connections between the worlds of academia and public policy. Led by Associate Professor Chappell Lawson, who serves as faculty director, and Drew Story, who serves as managing director, the MIT Policy Lab has supported over 110 policy impact projects to date. In this Q&A, Story discusses the purpose and motivations of the lab, its current projects, and his vision...

Celebrating Kendall Square’s past and shaping its...

October 23, 2023

Kendall Square’s community took a deep dive into the history and future of the region at the Kendall Square Association’s 15th annual meeting on Oct. 19. It’s no secret that Kendall Square, located in Cambridge, Massachusetts, moves fast. The event, titled “Looking Back, Looking Ahead,” gave community members a chance to pause and reflect on how far the region has come and to discuss efforts to shape where it’s going next. “The impact of the last 15 years of...

LIGO surpasses the quantum limit

October 23, 2023

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. In 2015, the Laser Interferometer Gravitational-Wave Observatory, or LIGO, made history when it made the first direct detection of gravitational waves, or ripples in space and time, produced by a pair of colliding black holes. Since then, the U.S. National Science...

Opening pathways for future supply chain leaders

October 20, 2023

Sit down with Maria Jesus Saenz of the MIT Center for Transportation and Logistics (CTL) to discuss her professional achievements and priorities, and you’re likely to come away with two questions: How has she become a thought leader in so many areas — from logistics strategies and supply chain education to human-AI collaboration and digital supply chain transformation, to name just a few? And what is behind her legendary energy and drive? The answer to both questions is passion...

Building on an enduring bond

October 20, 2023

Robert Robinson Taylor’s impressive legacy straddles two institutions. There’s MIT, where he studied architecture and became the Institute’s first African American graduate; and then there is Tuskegee University, originally the Tuskegee Institute, where Taylor spent most of his career, heading the architecture department of the historically Black college, helping to shape its educational philosophy that drew some inspiration from MIT’s, and designing and helping to build many of the buildings on the Tuskegee campus. While there have been ongoing...

Teaching students about photonics to build up...

October 20, 2023

In 2019, Kevin McComber ’05, PhD ’11 was at MIT working on integrated photonics — chip-based devices that send and receive signals using light — and set out to hire someone to design photonic chips. The experience made him realize just how little expertise the U.S. workforce has in integrated photonics design, a problem that’s part of a broader shortage of workers in semiconductor manufacturing. The insight would change the trajectory of McComber’s career. Despite having no background in...

Learning how to learn

October 19, 2023

Suppose you need to be on today’s only ferry to Martha’s Vineyard, which leaves at 2 p.m. It takes about 30 minutes (on average) to drive from where you are to the terminal. What time should you leave? This is one of many common real-life examples used by Richard “Dick” Larson, a post-tenure professor in the MIT Institute for Data, Systems, and Society (IDSS), to explore exemplary problem-solving in his new book “Model Thinking for Everyday Life: How to...

Soft optical fibers block pain while moving...

October 19, 2023

Scientists have a new tool to precisely illuminate the roots of nerve pain. Engineers at MIT have developed soft and implantable fibers that can deliver light to major nerves through the body. When these nerves are genetically manipulated to respond to light, the fibers can send pulses of light to the nerves to inhibit pain. The optical fibers are flexible and stretch with the body. The new fibers are meant as an experimental tool that can be used by...

To excel at engineering design, generative AI...

October 19, 2023

ChatGPT and other deep generative models are proving to be uncanny mimics. These AI supermodels can churn out poems, finish symphonies, and create new videos and images by automatically learning from millions of examples of previous works. These enormously powerful and versatile tools excel at generating new content that resembles everything they’ve seen before. But as MIT engineers say in a new study, similarity isn’t enough if you want to truly innovate in engineering tasks. “Deep generative models (DGMs)...
