Researchers from MIT and elsewhere have found that brown carbon – released from burning biomass – could have a larger impact on the Earth’s climate than originally thought, write University of British Columbia student Nealan Gerrebos and University of British Columbia Prof. Alan Bertram for The Conversation. “The results show a warming effect on the climate from brown carbon that is twice that of the previous estimate,” write Gerrebos and Bertram.
A stamp-sized reusable ultrasound sticker developed by researchers in Prof. Xuanhe Zhao’s research group has been named one of the best inventions of 2022 by TIME. “Unlike stretchy existing ultrasound wearables, which sometimes produce distorted images, the new device’s stiff transducer array can record high-resolution video of deep internal organs (e.g. heart, lungs) over a two-day period,” writes Alison Van Houten.
University of South Carolina Prof. Jennifer A. Frey reviews Prof. Kiernan Setiya’s new book “Life is Hard: How Philosophy Can Help Us Find Our Way” for The Wall Street Journal. Frey writes that Setiya's analysis "combines philosophical arguments and personal reflections on his own experience. He offers this in the hope that it will help readers better understand their own suffering and perhaps ease the weight of it."
Popular Science reporter Charlotte Hu writes that MIT researchers have developed a new machine learning model that can depict how the sound around a listener changes as they move through a certain space. “We’re mostly modeling the spatial acoustics, so the [focus is on] reverberations,” explains graduate student Yilun Du. “Maybe if you’re in a concert hall, there are a lot of reverberations, maybe if you’re in a cathedral, there are many echoes versus if you’re in a small room, there isn’t really any echo.”
Researchers from MIT and Boston Children’s Hospital are working on developing new technology that could help predict and identify diseases through audio recordings of a patient’s voice, reports Jim Morelli for Boston 25 News. “It’s almost like being Sherlock Holmes to voice, taking voice as a signal and trying to understand what’s going on behind it,” said Satrajit Ghosh, a principal research scientist at the McGovern Institute. “And can we backtrack from voice and say this is ‘Disorder A’ versus ‘Disorder B’?”
Researchers in Prof. Alison Wendtland’s group have found a way to change tertiary carbon stereochemistries using a photochemical decatungstate-catalyzed radical reaction, reports Derek Lowe for Science. This is “a neat opportunity to generate new isomers of known compounds (natural products, of course but many more as well, including med-chem SAR compounds), giving you some instant and relatively painless chemical diversity,” writes Lowe.
MIT researchers have developed a new technique aimed at protecting images from AI generators, reports Kyle Barr for Gizmodo. The program uses "data poisoning techniques to essentially disturb pixels within an image to create invisible noise, effectively making AI art generators incapable of generating realistic deepfakes based on the photos they’re fed,” reports Kyle Barr for Gizmodo."
Prof. Emeritus Tim Berners-Lee spoke at Lisbon’s Web Summit conference about Solid, an “open-sourced gambit to reinvent the web through new decentralized privacy-minded tools for wrangling data,” reports Harry McCracken for Fast Company. Solid was originally started as an MIT research project.
Researchers from MIT and other institutions have found that an AI system called KataGo can be consistently tricked into losing at the strategy game of Go, reports Jeremy Kahn for Fortune. This research highlights potential similar vulnerabilities in “other AI systems trained in a similar manner,” writes Kahn.
Writing for The Guardian, Prof. Kieran Setiya explores the pursuit of happiness. “What, then, should we strive for? Not happiness or an ideal life, but to find sufficient meaning in the world that we are glad to be alive, and to cope with grace when life is hard,” writes Setiya. “We won’t achieve perfection, but our lives may be good enough.”
A study by Prof. Emery Brown suggests that the combination of Covid-19 and anesthesia could prompt the human brain into a state of quiet that can last weeks or months, similar to how turtles quiet their neurons to survive winter, reports Carl Zimmer for The New York Times. The findings “might point to new ways to save people from brain damage: by intentionally putting people into this state, rather than doing so by accident.”
Research from Synlogic, a biotech company founded by Profs James Collins and Timothy Lu, has found that it’s the company’s engineered bacteria could provide some benefit to patients with a rare genetic disease, reports Emily Mullin for Wired. “Similar to how you might program a computer, we can tinker with the DNA of bacteria and have them do things like produce a drug at the right time and the right place, or in this case, break down a toxic metabolite,” says Lu.
Scientists at MIT have developed “a machine learning model that can capture how sounds in a room will propagate through space,” report Kyle Wiggers and Devin Coldewey for TechCrunch. “By modeling the acoustics, the system can learn a room’s geometry from sound recordings, which can then be used to build a visual rendering of a room,” write Wiggers and Coldewey.
Scientists from MIT, Duke and Stanford have developed a new technique to make gene therapies safer and more effective, reports Ryan Cross for The Boston Globe. “It’s about making these therapies much smarter and programmable,” says Jonathan S. Gootenberg, a research scientist at the McGovern Institute.
Writing for The Wall Street Journal, MIT Prof. Katherine Kellogg and Stanford Prof. Melissa Valentine explore the challenges of introducing AI technologies in the workplace, focusing on the fashion industry. "Getting workers to actually use the technologies will turn out to be just as important as making sure the systems work in the first place," they write.
