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.

 
Jane-Jane Chen: A model scientist who inspires...
Growing up in Taiwan, Jane-Jane Chen excelled at math and science, which, at that time, were promoted heavily by the government, and were taught at a high level. Learning rudimentary English as well, the budding scientist knew she wanted to come to the United States to continue her studies, after she earned a bachelor of science in agricultural chemistry from the National Taiwan University in Taipei. But the journey to becoming a respected scientist, with many years of notable...

MIT Energy and Climate Club mobilizes future...
One of MIT’s missions is helping to solve the world’s greatest problems — with a large focus on one of the most pressing topics facing the world today, climate change.The MIT Energy and Climate Club, (MITEC) formerly known as the MIT Energy Club, has been working since 2004 to inform and educate the entire MIT community about this urgent issue and other related matters. MITEC, one of the largest clubs on campus, has hundreds of active members from every...

The changing geography of “energy poverty”
A growing portion of Americans who are struggling to pay for their household energy live in the South and Southwest, reflecting a climate-driven shift away from heating needs and toward air conditioning use, an MIT study finds. The newly published research also reveals that a major U.S. federal program that provides energy subsidies to households, by assigning block grants to states, does not yet fully match these recent trends. The work evaluates the “energy burden” on households, which reflects...

Institute Professor Emeritus John Little, a founder...
MIT Institute Professor Emeritus John D.C. Little ’48, PhD ’55, an inventive scholar whose work significantly influenced operations research and marketing, died on Sept. 27, at age 96. Having entered MIT as an undergraduate in 1945, he was part of the Institute community over a span of nearly 80 years and served as a faculty member at the MIT Sloan School of Management since 1962. Little’s career was characterized by innovative computing work, an interdisciplinary and expansive research agenda,...

Artificial intelligence meets “blisk” in new DARPA-funded...
A recent award from the U.S. Defense Advanced Research Projects Agency (DARPA) brings together researchers from Massachusetts Institute of Technology (MIT), Carnegie Mellon University (CMU), and Lehigh University (Lehigh) under the Multiobjective Engineering and Testing of Alloy Structures (METALS) program. The team will research novel design tools for the simultaneous optimization of shape and compositional gradients in multi-material structures that complement new high-throughput materials testing techniques, with particular attention paid to the bladed disk (blisk) geometry commonly found in...

Study finds mercury pollution from human activities...
MIT researchers have some good environmental news: Mercury emissions from human activity have been declining over the past two decades, despite global emissions inventories that indicate otherwise. In a new study, the researchers analyzed measurements from all available monitoring stations in the Northern Hemisphere and found that atmospheric concentrations of mercury declined by about 10 percent between 2005 and 2020. They used two separate modeling methods to determine what is driving that trend. Both techniques pointed to a decline...

Bubble findings could unlock better electrode and...
Industrial electrochemical processes that use electrodes to produce fuels and chemical products are hampered by the formation of bubbles that block parts of the electrode surface, reducing the area available for the active reaction. Such blockage reduces the performance of the electrodes by anywhere from 10 to 25 percent. But new research reveals a decades-long misunderstanding about the extent of that interference. The findings show exactly how the blocking effect works and could lead to new ways of designing...

Teen uses pharmacology learned through MIT OpenCourseWare...
Tomás Orellana, a 17-year-old high school student in Chile, had a vision: to create a kit of medicinal plants for Chilean school infirmaries. But first, he needed to understand the basic principles of pharmacology. That’s when Orellana turned to the internet and stumbled upon a gold mine of free educational resources and courses on the MIT OpenCourseWare website. Right away, Orellana completed class HST.151 (Principles of Pharmacology), learning about the mechanisms of drug action, dose-response relations, pharmacokinetics, drug delivery systems,...

Applying risk and reliability analysis across industries
On Feb. 1, 2003, the space shuttle Columbia disintegrated as it returned to Earth, killing all seven astronauts on board. The tragic incident compelled NASA to amp up their risk safety assessments and protocols. They knew whom to call: Curtis Smith PhD ’02, who is now the KEPCO Professor of the Practice of Nuclear Science and Engineering at MIT. The nuclear community has always been a leader in probabilistic risk analysis and Smith’s work in risk-related research had made...

MIT alumnus Victor Ambros ’75, PhD ’79 and Gary Ruvkun, who did his postdoctoral training at MIT, will share the 2024 Nobel Prize in Physiology or Medicine, the Royal Swedish Academy of Sciences announced this morning in Stockholm. Ambros, a professor at the University of Massachusetts Chan Medical School, and Ruvkun, a professor at Harvard Medical School and Massachusetts General Hospital, were honored for their discovery of microRNA, a class of tiny RNA molecules that play a critical role...

Translating MIT research into real-world results
Inventive solutions to some of the world’s most critical problems are being discovered in labs, classrooms, and centers across MIT every day. Many of these solutions move from the lab to the commercial world with the help of over 85 Institute resources that comprise MIT’s robust innovation and entrepreneurship (I&E) ecosystem. The Abdul Latif Jameel Water and Food Systems Lab (J-WAFS) draws on MIT’s wealth of I&E knowledge and experience to help researchers commercialize their breakthrough technologies through the J-WAFS...

3 Questions: Bridging anthropology and engineering for...
In 2021, Michael Short, an associate professor of nuclear science and engineering, approached professor of anthropology Manduhai Buyandelger with an unusual pitch: collaborating on a project to prototype a molten salt heat bank in Mongolia, Buyandelger’s country of origin and place of her scholarship. It was also an invitation to forge a novel partnership between two disciplines that rarely overlap. Developed in collaboration with the National University of Mongolia (NUM), the device was built to provide heat for people in...

How AI is improving simulations with smarter...
Imagine you’re tasked with sending a team of football players onto a field to assess the condition of the grass (a likely task for them, of course). If you pick their positions randomly, they might cluster together in some areas while completely neglecting others. But if you give them a strategy, like spreading out uniformly across the field, you might get a far more accurate picture of the grass condition. Now, imagine needing to spread out not just in...

An interstellar instrument takes a final bow
They planned to fly for four years and to get as far as Jupiter and Saturn. But nearly half a century and 15 billion miles later, NASA’s twin Voyager spacecraft have far exceeded their original mission, winging past the outer planets and busting out of our heliosphere, beyond the influence of the sun. The probes are currently making their way through interstellar space, traveling farther than any human-made object. Along their improbable journey, the Voyagers made first-of-their-kind observations at...

Q&A: A new initiative to help strengthen...
In the United States and around the world, democracy is under threat. Anti-democratic attitudes have become more prevalent, partisan polarization is growing, misinformation is omnipresent, and politicians and citizens sometimes question the integrity of elections.  With this backdrop, the MIT Department of Political Science is launching an effort to establish a Strengthening Democracy Initiative. In this Q&A, department head David Singer, the Raphael Dorman-Helen Starbuck Professor of Political Science, discusses the goals and scope of the initiative. Q: What...
