Say WOW

Suborbital space tourism finally arrives | FCC prepares to run public C-band auction | The big four in the U.S. launch industry — United Launch Alliance, SpaceX, Blue Origin and Northrop Grumman — hope to be one of two providers that will receive five-year contracts later this year to launch national security payloads starting in 2022. | China’s launch rate stays high | The International Space Station is the largest ever crewed object in space.

 
A new chapter for space sustainability
Each day, new and innovative space technologies are being developed in countries around the world, and with that, a steady stream of satellites, rockets, cargo ships, and crew vehicles are being launched into the Earth’s orbit and beyond. So what happens to these systems when they come to the end of their functional life, or malfunction and break?   Some are programmed to re-enter the Earth’s atmosphere where, if all goes well, they incinerate safely upon entry. Some are programmed...

Engineered yeast could expand biofuels’ reach
Boosting production of biofuels such as ethanol could be an important step toward reducing global consumption of fossil fuels. However, ethanol production is limited in large part by its reliance on corn, which isn’t grown in large enough quantities to make up a significant portion of U.S. fuel needs. To try to expand biofuels’ potential impact, a team of MIT engineers has now found a way to expand the use of a wider range of nonfood feedstocks to produce...

One nation under contract
For decades, the famous American poet Wallace Stevens lived a double life: He was also an insurance executive. Occasionally, Stevens would write about his day job. It may not be his most transcendent work, but the essays are revealing. “If private companies can continue to expand with profit and adapt to the changing needs of changing times, no question of nationalization is likely to arise under our system,” Wallace asserted in one 1937 piece, which he wrote while a...

3Q: Why “nuclear batteries” offer a new...
We may be on the brink of a new paradigm for nuclear power, a group of nuclear specialists suggested recently in The Bridge, the journal of the National Academy of Engineering. Much as large, expensive, and centralized computers gave way to the widely distributed PCs of today, a new generation of relatively tiny and inexpensive factory-built reactors, designed for autonomous plug-and-play operation similar to plugging in an oversized battery, is on the horizon, they say. These proposed systems could...

As novel sights become familiar, different brain...
To focus on what’s new, we disregard what’s not. A new study by researchers at MIT’s Picower Institute for Learning and Memory substantially advances understanding of how a mammalian brain enables this “visual recognition memory.” Dismissing the things in a scene that have proven to be of no consequence is an essential function because it allows animals and people to quickly recognize the new things that need to be assessed, says Mark Bear, Picower Professor in the Department of...

Four MIT faculty members receive 2021 US...
The U.S. Department of Energy (DoE) recently announced the names of 83 scientists who have been selected for their 2021 Early Career Research Program. The list includes four faculty members from MIT: Riccardo Comin of the Department of Physics; Netta Engelhardt of the Department of Physics and Center for Theoretical Physics; Philip Harris of the Department of Physics and Laboratory for Nuclear Science; and Mingda Li of the Department of Nuclear Science and Engineering. Each year, the DoE selects...

Tackling air pollution with autonomous drones
Hovering 100 meters above a densely populated urban residential area, the drone takes a quiet breath. Its goal is singular: to systematically measure air quality across the metropolitan landscape, providing regular updates to a central communication module where it docks after its patrol, awaiting a new set of instructions. The central module integrates each new data point provided by a small drone fleet, processing them against wind and traffic patterns and historical pollution hot spot information. Then the fleet...

From NYC zookeeper to aspiring architect
The crowd gasped as the zookeeper entered the room, cradling an armadillo between his hands. For many in the audience, this was their first chance at seeing this unique animal up close. James Brice smiled as he watched faces transform from reservation to delight. As a child growing up in New York City, Brice had always enjoyed sharing his love for the environment with others. While he pursued an applied physics degree as an undergraduate, teaching was often on...

Revisiting a quantum past for a fusion...
“I’m going back. It’s almost like a cycle in your life,” muses physicist Abhay Ram. Ram, a principal research scientist at the Plasma Science and Fusion Center (PSFC) at MIT, is returning to a field he first embraced as a graduate student at the Institute 50 years ago: quantum mechanics. Funded by the U.S. Department of Energy, he is exploring different pathways for using the power and speed of quantum computing — when it is eventually available — to...

Four researchers earn interdisciplinary Schmidt Science Fellowships
Four MIT-affiliated researchers are among 28 around the world to have been named to a competitive Schmidt Science Fellowship, an award created in 2017 to advance interdisciplinary studies among early-career researchers. “An initiative of Schmidt Futures, delivered in partnership with the Rhodes Trust, the Schmidt Science Fellows program brings together the brightest minds who have completed a PhD in the natural sciences, mathematics, engineering, or computing, and places them in a postdoctoral fellowship in a field different from their...

A unique collaboration with US Special Operations...
When General Richard D. Clarke, commander of the U.S. Special Operations Command (USSOCOM), visited MIT in fall 2019, he had artificial intelligence on the mind. As the commander of a military organization tasked with advancing U.S. policy objectives as well as predicting and mitigating future security threats, he knew that the acceleration and proliferation of artificial intelligence technologies worldwide would change the landscape on which USSOCOM would have to act. Clarke met with Anantha P. Chandrakasan, dean of the...

Online hub for research and teaching brings...
Computing touches every aspect of teaching and learning at MIT, and the humanities are no exception, with scholars across disciplines using computational tools to answer critical questions in humanistic research. MIT is uniquely positioned to innovate in the digital humanities, with widespread skills in coding and deep engagement in the humanities. Bridging the gap — creating a “bilingual” community, as MIT President L. Rafael Reif calls it — to make connections across diverse research interests will be one key...

How the surfaces of silicone breast implants...
Every year, about 400,000 people receive silicone breast implants in the United States. According to data from the U.S. Food and Drug Administration, a majority of those implants needs to be replaced within 10 years due to the buildup of scar tissue and other complications. A team led by MIT researchers has now systematically analyzed how the varying surface architecture found in these implants influences the development of adverse effects, which in rare cases can include an unusual type...

Physicists bring human-scale object to near standstill,...
To the human eye, most stationary objects appear to be just that — still, and completely at rest. Yet if we were handed a quantum lens, allowing us to see objects at the scale of individual atoms, what was an apple sitting idly on our desk would appear as a teeming collection of vibrating particles, very much in motion. In the last few decades, physicists have found ways to super-cool objects so that their atoms are at a near...

Melissa Nobles named MIT’s next chancellor
MIT has announced that its next chancellor will be Melissa Nobles, an accomplished scholar who has led the School of Humanities, Arts, and Social Sciences since 2015. As chancellor, Nobles will oversee student life and learning, in a broad role that encompasses undergraduate and graduate education and student well-being, as well as strategic planning and fundraising for “all things students.” Nobles is set to become the new chancellor at a time of significant challenges, including the Covid-19 pandemic and...
