The winners are selected by an independent panel of expert judges. R&D World, an online publication that serves research scientists and engineers worldwide, announces the awards. The winning technologies are diverse in their applications. One technology empowers medics...

Carina Letong Hong named a 2022 Rhodes...

November 17, 2021

Carina Letong Hong from Guangzhou, China, is a winner of the Rhodes Scholarship (China Constituency). As a Rhodes Scholar, she will pursue graduate studies in mathematics at Oxford University. At MIT, Hong is a junior double-majoring in mathematics and physics. She hopes to become an academic and devote her life to solving conjectures and building communities. Hong has taken over 20 graduate courses, and plans to graduate in the spring of 2022 after three years at MIT. She has...

Theoretical breakthrough could boost data storage

November 16, 2021

A trio of researchers that includes William Kuszmaul — a computer science PhD student at MIT — has made a discovery that could lead to more efficient data storage and retrieval in computers. The team’s findings relate to so-called “linear-probing hash tables,” which were introduced in 1954 and are among the oldest, simplest, and fastest data structures available today. Data structures provide ways of organizing and storing data in computers, with hash tables being one of the most commonly...

The poetry of physics

November 16, 2021

“With skin brushed then tangled, with the apple touched at the supermarket then tangled,with the tear wiped then woven away,tangled with even things very distant like Mars dust,that unravel themselves when /touched by our gaze…” —Excerpt from Miriam Manglani’s poem “Makinde’s Quantum World,” about Makinde Ogunnaike’s quantum physics research Senior MIT physics doctoral student Olumakinde “Makinde” Ogunnaike briefly traded his research for verse as a participant in The Poetry of Science, an initiative funded by the Cambridge Arts Council...

Studying learner engagement during the Covid-19 pandemic

November 16, 2021

While massive open online classes (MOOCs) have been a significant trend in higher education for many years now, they have gained a new level of attention during the Covid-19 pandemic. Open online courses became a critical resource for a wide audience of new learners during the first stages of the pandemic — including students whose academic programs had shifted online, teachers seeking online resources, and individuals suddenly facing lockdown or unemployment and looking to build new skills. Mary Ellen...

Is watching believing?

November 16, 2021

It might seem that video would be a singularly influential medium for spreading information online. But a new experiment conducted by MIT researchers finds that video clips have only a modestly larger impact on political persuasion than the written word does. “Our conclusion is that watching video is not much more persuasive than reading text,” says David Rand, an MIT professor and co-author of a new paper detailing the study’s results. The study comes amid widespread concern about online...

Managing Covid-19 at MIT this fall: “So...

November 15, 2021

Despite the ongoing Covid-19 pandemic, nearly 20,000 people are now studying, working, or living at MIT on any given day. Thanks to a robust plan to mitigate the spread of Covid-19 on campus — masking, attesting, testing, and access control — the number of positive Covid-19 cases has remained very low (at or below 0.1% of tests conducted) in recent weeks. Because of that statistic, nearly all classes, labs, and offices have been, and remain, in-person. Ian Waitz, vice...

New material could be two superconductors in...

November 15, 2021

MIT physicists and colleagues have demonstrated an exotic form of superconductivity in a new material the team synthesized only about a year ago. Although predicted in the 1960s, until now this type of superconductivity has proven difficult to stabilize. Further, the scientists found that the same material can potentially be manipulated to exhibit yet another, equally exotic form of superconductivity. The work was reported in the Nov. 3 issue of the journal Nature. The demonstration of finite momentum superconductivity...

A key brain region responds to faces...

November 15, 2021

Within the visual cortex of the adult brain, a small region is specialized to respond to faces, while nearby regions show strong preferences for bodies or for scenes such as landscapes. Neuroscientists have long hypothesized that it takes many years of visual experience for these areas to develop in children. However, a new MIT study suggests that these regions form much earlier than previously thought. In a study of babies ranging in age from two to nine months, the...

For stem cells, bigger doesn’t mean better

November 12, 2021

MIT biologists have answered an important biological question: Why do cells control their size? Cells of the same type are strikingly uniform in size, while cell size differs between different cell types. This raises the question of whether cell size is important for cellular physiology. The new study suggests that cellular enlargement drives a decline in function of stem cells. The researchers found that blood stem cells, which are among the smallest cells in the body, lose their ability to...

Dexterous robotic hands manipulate thousands of objects...

November 12, 2021

At just one year old, a baby is more dexterous than a robot. Sure, machines can do more than just pick up and put down objects, but we’re not quite there as far as replicating a natural pull toward exploratory or sophisticated dexterous manipulation goes. Artificial intelligence firm OpenAI gave it a try with Dactyl (meaning “finger,” from the Greek word “daktylos”), using their humanoid robot hand to solve a Rubik’s cube with software that’s a step toward more...

MIT makes strides on climate action plan

November 12, 2021

Two recent online events related to MIT’s ambitious new climate action plan highlighted several areas of progress, including uses of the campus as a real-life testbed for climate impact research, the creation of new planning bodies with opportunities for input from all parts of the MIT community, and a variety of moves toward reducing the Institute’s own carbon footprint in ways that may also provide a useful model for others. On Monday, MIT’s Office of Sustainability held its seventh...

Meet Director of Philanthropy and Foresight Charles...

November 11, 2021

Nov 10, 2021 Charles Tsai, Director of Philanthropy and Foresight Charles Tsai lives in Vancouver, and brings his deep experience in philanthropy to IFTF—a field that he believes is due for some big, structural change. “Typically, people talk about philanthropy as society’s risk capital,” Charles says. “But the problem is, we haven’t really used that money to take big risks and make big bets to bring about the transformations that we need in the world.” He was drawn to...

MIT Press announces Grant Program for Diverse...

November 10, 2021

In keeping with its mission and longstanding commitment to grow diversity in the ranks of published authors, the MIT Press has announced the launch of the Grant Program for Diverse Voices. The initiative will expand funding for new work by authors whose voices have been excluded and chronically underrepresented across the arts, humanities, and sciences. The grant program will be supported by the press’s existing Fund for Diverse Voices. The MIT Press welcomes applications from new or returning authors...

Radio-frequency wave scattering improves fusion simulations

November 10, 2021

In the quest for fusion energy, understanding how radio-frequency (RF) waves travel (or “propagate”) in the turbulent interior of a fusion furnace is crucial to maintaining an efficient, continuously operating power plant. Transmitted by an antenna in the doughnut-shaped vacuum chamber common to magnetic confinement fusion devices called tokamaks, RF waves heat the plasma fuel and drive its current around the toroidal interior. The efficiency of this process can be affected by how the wave’s trajectory is altered (or...
