“Visualizing the Proton” through animation and film
Try to picture a proton — the minute, positively charged particle within an atomic nucleus — and you may imagine a familiar, textbook diagram: a bundle of billiard balls representing quarks and gluons. From the solid sphere model first proposed by John Dalton in 1803 to the quantum model put forward by Erwin Schrödinger in […]
Tackling chemical synthesis and advocacy
Azin Saebi was born and raised in Iran, emigrating to the U.S. with her family at 18 after graduating from high school. Now a fifth-year graduate student in chemistry, Saebi never intended to stay permanently; she initially expected to go back to Iran to attend university. With that in mind, when leaving for the U.S., […]
What choices does the world need to make to keep global warming below 2 C?
When the 2015 Paris Agreement set a long-term goal of keeping global warming “well below 2 degrees Celsius, compared to pre-industrial levels” to avoid the worst impacts of climate change, it did not specify how its nearly 200 signatory nations could collectively achieve that goal. Each nation was left to its own devices to reduce […]

Scientists develop the largest, most detailed model of the early universe to date
It all started around 13.8 billion years ago with a big, cosmological “bang” that brought the universe suddenly and spectacularly into existence. Shortly after, the infant universe cooled dramatically and went completely dark. Then, within a couple hundred million years after the Big Bang, the universe woke up, as gravity gathered matter into the first […]
Study finds neurons that encode the outcomes of actions
When we make complex decisions, we have to take many factors into account. Some choices have a high payoff but carry potential risks; others are lower risk but may have a lower reward associated with them. A new study from MIT sheds light on the part of the brain that helps us make these types […]
Yukiko Yamashita, unraveler of stem cells’ secrets
When cells divide, they usually generate two identical daughter cells. However, there are some important exceptions to this rule: When stem cells divide, they often produce one differentiated cell along with another stem cell, to maintain the pool of stem cells. Yukiko Yamashita has spent much of her career exploring how these “asymmetrical” cell divisions […]

Physicists find direct evidence of strong electron correlation in a 2D material for the first time
In recent years, physicists have discovered materials that are able to switch their electrical character from a metal to an insulator, and even to a superconductor, which is a material in a friction-free state that allows electrons to flow with zero resistance. These materials, which include “magic-angle” graphene and other synthesized two-dimensional materials, can shift […]
A fabric that “hears” your heartbeat
Having trouble hearing? Just turn up your shirt. That’s the idea behind a new “acoustic fabric” developed by engineers at MIT and collaborators at Rhode Island School of Design. The team has designed a fabric that works like a microphone, converting sound first into mechanical vibrations, then into electrical signals, similarly to how our ears […]
Look! Up in the sky! Is it a planet? Nope, just a star
The first worlds beyond our solar system were discovered three decades ago. Since then, close to 5,000 exoplanets have been confirmed in our galaxy. Astronomers have detected another 5,000 planetary candidates — objects that might be planets but have yet to be confirmed. Now, the list of planets has shrunk by at least three. In […]
Microbes and minerals may have set off Earth’s oxygenation
For the first 2 billion years of Earth’s history, there was barely any oxygen in the air. While some microbes were photosynthesizing by the latter part of this period, oxygen had not yet accumulated at levels that would impact the global biosphere. But somewhere around 2.3 billion years ago, this stable, low-oxygen equilibrium shifted, and […]
Yen-Jie Lee probes particle collision data for clues to the universe’s origins
When Yen-Jie Lee came to MIT as a graduate student in 2006, it was a bit of a culture shock. The aspiring particle physicist had studied physics at National Taiwan University before his career took a hiatus in the forested mountains of Taiwan. There, he worked as a marine corps lieutenant to fulfill the nation’s […]
Study: Ice flow is more sensitive to stress than previously thought
The rate of glacier ice flow is more sensitive to stress than previously calculated, according to a new study by MIT researchers that upends a decades-old equation used to describe ice flow. Stress in this case refers to the forces acting on Antarctic glaciers, which are primarily influenced by gravity that drags the ice down […]
Objection: No one can understand what you’re saying
Legal documents, such as contracts or deeds, are notoriously difficult for nonlawyers to understand. A new study from MIT cognitive scientists has determined just why these documents are often so impenetrable. After analyzing thousands of legal contracts and comparing them to other types of texts, the researchers found that lawyers have a habit of frequently […]
New MRI probe can reveal more of the brain’s inner workings
Using a novel probe for functional magnetic resonance imaging (fMRI), MIT biological engineers have devised a way to monitor individual populations of neurons and reveal how they interact with each other. Similar to how the gears of a clock interact in specific ways to turn the clock’s hands, different parts of the brain interact to […]
Study reveals chemical link between wildfire smoke and ozone depletion
The Australian wildfires in 2019 and 2020 were historic for how far and fast they spread, and for how long and powerfully they burned. All told, the devastating “Black Summer” fires blazed across more than 43 million acres of land, and extinguished or displaced nearly 3 billion animals. The fires also injected over 1 million […]
Chemical synthesis yields potential antibiotic
Chemists at MIT have developed a novel way to synthesize himastatin, a natural compound that has shown potential as an antibiotic. Using their new synthesis, the researchers were able not only to produce himastatin but also to generate variants of the molecule, some of which also showed antimicrobial activity. They also discovered that the compound […]
More sensitive X-ray imaging
Scintillators are materials that emit light when bombarded with high-energy particles or X-rays. In medical or dental X-ray systems, they convert incoming X-ray radiation into visible light that can then be captured using film or photosensors. They’re also used for night-vision systems and for research, such as in particle detectors or electron microscopes. Researchers at […]
Physicists observe an exotic “multiferroic” state in an atomically thin material
MIT physicists have discovered an exotic “multiferroic” state in a material that is as thin as a single layer of atoms. Their observation is the first to confirm that multiferroic properties can exist in a perfectly two-dimensional material. The findings, published today in Nature, pave the way for developing smaller, faster, and more efficient data-storage […]
Singing in the brain
For the first time, MIT neuroscientists have identified a population of neurons in the human brain that lights up when we hear singing, but not other types of music. These neurons, found in the auditory cortex, appear to respond to the specific combination of voice and music, but not to either regular speech or instrumental […]
A “hot Jupiter’s” dark side is revealed in detail for first time
MIT astronomers have obtained the clearest view yet of the perpetual dark side of an exoplanet that is “tidally locked” to its star. Their observations, combined with measurements of the planet’s permanent day side, provide the first detailed view of an exoplanet’s global atmosphere. “We’re now moving beyond taking isolated snapshots of specific regions of […]
Can machine-learning models overcome biased datasets?
Artificial intelligence systems may be able to complete tasks quickly, but that doesn’t mean they always do so fairly. If the datasets used to train machine-learning models contain biased data, it is likely the system could exhibit that same bias when it makes decisions in practice. For instance, if a dataset contains mostly images of […]
Protein structure offers clues to drug-resistance mechanism
MIT chemists have discovered the structure of a protein that can pump toxic molecules out of bacterial cells. Proteins similar to this one, which is found in E. coli, are believed to help bacteria become resistant to multiple antibiotics. Using nuclear magnetic resonance (NMR) spectroscopy, the researchers were able to determine how the structure of […]
Dendrites may help neurons perform complicated calculations
Within the human brain, neurons perform complex calculations on information they receive. Researchers at MIT have now demonstrated how dendrites — branch-like extensions that protrude from neurons — help to perform those computations. The researchers found that within a single neuron, different types of dendrites receive input from distinct parts of the brain, and process […]
A new atlas of cells that carry blood to the brain
While neurons and glial cells are by far the most numerous cells in the brain, many other types of cells play important roles. Among those are cerebrovascular cells, which form the blood vessels that deliver oxygen and other nutrients to the brain. Those cells, which comprise only 0.3 percent of the brain’s cells, also make […]
