Prof. Susan Solomon speaks with Wall Street Journal reporter Nidhi Subbaraman about her research and another recent study that provides evidence wildfire smoke poses a threat to the ozone layer. “It’s fair to say that, at least for a few months, these wildfires canceled out the last decade of all the efforts that we put in over the Montreal Protocol,” says Solomon. “I think there’s every reason to believe this is going to happen more often, and it’s going to act to slow down the recovery of the ozone depletion.”

Bloomberg News spotlights how MIT researchers have developed a new material that works like a microphone, converting sounds into vibrations and then electrical signals. “The development means the possibility of clothes that act as hearing aids, clothes that answer phone calls, and garments that track heart and breathing rates,” writes Bloomberg News.

Researchers from MIT and the Rhode Island School of Design have developed a wearable fabric microphone that can detect and transmit soundwaves and convert them into electrical signals, reports Shi En Kim for Popular Science. “Computers are going to really become fabrics," says Prof. Yoel Fink. "We’re getting very close.”

MIT researchers have created a flexible fiber that can generate electrical impulses that are conveyed to the brain as sound, reports Miriam Fauzia for The Daily Beast. “The researchers see endless possibilities for their smart fabric,” writes Fauzia. “The obvious application is in improving hearing aids, which Fink said have trouble discerning the direction of sound, particularly in noisy environments. But the fabric could also help engineers design wearable fabrics that can measure vital signs, monitor space dust in new kinds of spacecraft, and listen for signs of deterioration in buildings like emerging cracks and strains.”

Graduate student Matt Groh speaks with Scientific American reporter Sarah Vitak about his team’s work studying whether human detection or artificial intelligence is better at identifying deepfakes and misinformation online. “One of the things that we would suggest for the future development of these systems is trying to figure out ways to explain why the AI is making a decision,” says Groh.

Forbes contributor David Bressan writes that a new study by MIT researchers proposes that oxygen began accumulating in early Earth’s atmosphere due to interactions between marine microbes and minerals in ocean sediments. The researchers hypothesize that “these interactions helped prevent oxygen from being consumed, setting off a self-amplifying process where more and more oxygen was made available to accumulate in the atmosphere,” writes Bressan.

Scientists from MIT, Yale, Newcastle University, the non-profit Galapagos Conservancy and other institutions have discovered a new species of living tortoise on the Galapagos Islands, reports Audrey Carleton for Vice. “If the findings are confirmed to represent a new species, the living tortoises on the island may need a new name, writes Carleton.

MIT researchers have developed a new water-free system that uses static electricity to clear dust from solar panels, reports Miriam Fauzia for The Daily Beast. “By using this technique, we can recover up to 95 percent of a solar panel’s power output,” explains graduate student Sreedath Panat.

Institute Prof. Robert Langer, whose “innovations have helped create more than 100 products from artificial skin to messenger RNA (mRNA) vaccines,” speaks with Guardian reporter Zoë Corbyn. “I think it’s important to stress how much engineers can and have changed the world for the better,” says Langer. “It’s a thrill for me to see engineering and biology improving people’s lives; that’s been my dream from the beginning.”

New Scientist reporter Chen Ly writes that MIT researchers have developed a new technique that uses static electricity to remove the dust from solar panels, which could save around 45 billion liters of water annually. “I think water is a precious commodity that is very undervalued,” says Prof. Kripa Varanasi. “What I’m hoping is this will spur more people to think about water issues.”

Indian Express reporter Sethu Pradeep writes that MIT researchers have developed a low-energy security chip designed to prevent side channel attacks on smart devices. “It can be used in any sensor nodes which connects user data,” explains graduate student Saurav Maji. “For example, it can be used in monitoring sensors in the oil and gas industry, it can be used in self-driving cars, in fingerprint matching devices and many other applications.”

OPT Industries, an MIT spinoff, has created InstaSwab, a nasal swab “up to 20 times more effective in bacterial sample elution,” reports Brian Heater for TechCrunch. “With the ability to print around the clock, the firm also believes it can play a pivotal role in addressing supply chain concerns — a long-time goal for additive manufacturing,” writes Heater.

Smoke from Australian wildfires in 2019 and 2020 appears to have contributed to the breakdown of the ozone layer, according to a new study by MIT scientists, reports Sharon Udasin for The Hill. “The new study establishes the first direct link between wildfire smoke and ozone depletion,” writes Udasin. 

Daily Beast reporter Miriam Fauzia writes that a new study by MIT scientists finds that smoke particles from wildfires are slowing the recovery of the ozone layer.

BBC News correspondent Helen Briggs writes that MIT scientists have found that increasing wildfires may slow the recovery of the ozone layer. "All the hard work that the world went to to reduce chlorofluorocarbons (ozone-depleting chemicals once used in aerosol sprays) is not paying off as well in the areas that experience extreme wildfires," explains Prof. Susan Solomon. "The best hope would be that we reduce global warming gases also and stop increasing the wildfires, but that's obviously more difficult."
