Educating future naval leaders
Since 1901, MIT has offered a graduate program unlike any other at the Institute. The Naval Construction and Engineering program in the Department of Mechanical Engineering educates active duty officers in the U.S. Navy, U.S Coast Guard, and foreign navies. Every year, the U.S. Navy chooses 10 officers to enroll in the program, which is often referred to as Course 2N. “This is a valuable relationship, both from MIT’s perspective and the Navy’s perspective. We have access to the...

Using light to manipulate neuron excitability
Nearly 20 years ago, scientists developed ways to stimulate or silence neurons by shining light on them. This technique, known as optogenetics, allows researchers to discover the functions of specific neurons and how they communicate with other neurons to form circuits. Building on that technique, MIT and Harvard University researchers have now devised a way to achieve longer-term changes in neuron activity. With their new strategy, they can use light exposure to change the electrical capacitance of the neurons’...

An automated way to assemble thousands of...
The manufacturing industry (largely) welcomed artificial intelligence with open arms. Less of the dull, dirty, and dangerous? Say no more. Planning for mechanical assemblies still requires more than scratching out some sketches, of course — it’s a complex conundrum that means dealing with arbitrary 3D shapes and highly constrained motion required for real-world assemblies.  Human engineers, understandably, need to jump in the ring and manually design assembly plans and instructions before sending the parts to assembly lines, and this...

Three MIT seniors win 2024 Schwarzman Scholarships
Three MIT seniors — Sara V. Fernandez, Amanda Hu, and Brigette Wang — have been named 2024 Schwarzman Scholars and will join the program’s eighth cohort, consisting of 151 scholars from 36 countries. The students were selected from a pool of over 3,000 applicants. Schwarzman Scholars pursue a master’s degree in global affairs at Tsinghua University in Beijing. The fellowship program aims to develop leadership skills and deepen understanding of China’s changing role in the world. Candidates are chosen...

A faster way to preserve privacy online
Searching the internet can reveal information a user would rather keep private. For instance, when someone looks up medical symptoms online, they could reveal their health conditions to Google, an online medical database like WebMD, and perhaps hundreds of these companies’ advertisers and business partners. For decades, researchers have been crafting techniques that enable users to search for and retrieve information from a database privately, but these methods remain too slow to be effectively used in practice. MIT researchers...

Q&A: Pouya Alimagham on the protest movement...
Today’s protests in Iran have been cited as the biggest threat the Islamic Republic has faced since it seized power in 1979. Ignited over the regime’s mandatory veiling of women and the recent death of Mahsa Amini while in morality police custody, the uprising is rooted in the Iranian people’s long struggle for freedom, says Pouya Alimagham Alimagham, a historian of the modern Middle East. In his research, Alimagham, an expert on Iran, Iraq, and the Levant, explores such...

MacGregor House gains a well-being graduate resident...
The noise of a construction site often annoys the people living and working nearby. But at MIT, it can lead to creativity and innovation. Such was the case with the creation of the new well-being graduate resident advisor (WGRA) role at MacGregor House. With the construction of a new apartment in the residence hall, heads-of-house Professor Larry Sass and his wife, psychologist Terry Sass, saw the apartment as an opportunity to add a graduate resident advisor (GRA). In discussions...

School of Science appoints 10 faculty to...
The School of Science has announced that 10 of its faculty members have been appointed to named professorships. The faculty members selected for these positions receive additional support to pursue their research and develop their careers. Camilla Cattania has been named a Cecil and Ida Green Career Development Professor in the Department of Earth, Atmospheric and Planetary Sciences. Her research uses theoretical and computational methods to better understand how faults slip during and between earthquakes, with a focus on...

Mining for the clean energy transition
In a world powered increasingly by clean energy, drilling for oil and gas will gradually give way to digging for metals and minerals. Today, the “critical minerals” used to make electric cars, solar panels, wind turbines, and grid-scale battery storage are facing soaring demand — and some acute bottlenecks as miners race to catch up. According to a report from the International Energy Agency, by 2040, the worldwide demand for copper is expected to roughly double; demand for nickel...

Using game engines and “twins” to co-create...
Imagine entering a 3D virtual story world that’s a digital twin of an existing physical space but also doubles as a vessel to dream up speculative climate stories and collective designs. Then, those imagined worlds are translated back into concrete plans for our physical spaces. Five multidisciplinary teams recently convened at MIT — virtually — for the inaugural WORLDING workshop. In a weeklong series of research and development gatherings, the teams met with MIT scientists, staff, fellows, students and...

Large language models help decipher clinical notes
Electronic health records (EHRs) need a new public relations manager. Ten years ago, the U.S. government passed a law that required hospitals to digitize their health records with the intent of improving and streamlining care. The enormous amount of information in these now-digital records could be used to answer very specific questions beyond the scope of clinical trials: What’s the right dose of this medication for patients with this height and weight? What about patients with a specific genomic...

MIT researchers use quantum computing to observe...
For the first time, researchers at MIT, Caltech, Harvard University, and elsewhere sent quantum information across a quantum system in what could be understood as traversing a wormhole. Though this experiment didn’t create a disruption of physical space and time in the way we might understand the term “wormhole” from science fiction, calculations from the experiment showed that qubits traveled from one system of entangled particles to another in a model of gravity. This experiment performed on the Sycamore...

A targeted approach to reducing the health...
To clear the way for planting wheat in November, a farmer in Punjab, India, sets aflame the leftover straw, or stubble, of a harvested rice paddy crop in October. The burning residue fills the air with carbon monoxide, ozone, and fine particulate matter (PM2.5) that will make it harder to breathe for days afterward and for miles around. It’s a scene that’s replicated on about 2 million farms in the Punjab and Haryana states of northwest India every autumn...

Communications system achieves fastest laser link from...
In May 2022, the TeraByte InfraRed Delivery (TBIRD) payload onboard a small CubeSat satellite was launched into orbit 300 miles above Earth’s surface. Since then, TBIRD has delivered terabytes of data at record-breaking rates of up to 100 gigabits per second — 100 times faster than the fastest internet speeds in most cities — via an optical communication link to a ground-based receiver in California. This data rate is more than 1,000 times higher than that of the radio-frequency links...

Mysteriously bright flash is a black hole...
Earlier this year, astronomers were keeping tabs on data from the Zwicky Transient Facility, an all-sky survey based at the Palomar Observatory in California, when they detected an extraordinary flash in a part of the sky where no such light had been observed the night before. From a rough calculation, the flash appeared to give off more light than 1,000 trillion suns. The team, led by researchers at NASA, Caltech, and elsewhere, posted their discovery to an astronomy newsletter,...
