MIT researchers have developed a new underwater system that could enable long-range and low-power underwater communication, reports Edd Gent for IEEE Spectrum. “The reason why this is really exciting is because now you start opening up many of the coastal monitoring applications,” says Prof. Fadel Adib. “It’s a turning point from this being a technology that is intellectually super interesting that we hope will work, to saying we know that this works and we have a path to deployment.”

Prof. Emeritus Kerry Emanuel speaks with The Hill reporter Zack Budryk about how Hurricane Idalia will impact rural Florida. “The thing that makes [Idalia] a little bit unusual is that it hit a part of the Florida coastline which has experienced very few hurricane-level landfalls in the last hundred years,” says Emanuel.

Prof. Emeritus Kerry Emanuel speaks with Jeff Martin at the Associated Press about the potential influence of the supermoon on Hurricane Idalia. “When the moon is full, the sun and the moon are pulling in the same direction, which has the effect of increasing tides above normal ranges” says Emanuel.

In an article he co-authored for Fortune, postdoctoral associate Matthew Hughes explains how extreme heat affects different kinds of machines. “In general, the electronics contained in devices like cellphones, personal computers and data centers consist of many kinds of materials that all respond differently to temperature changes,” they write. “So as the temperature increases, different kinds of materials deform differently, potentially leading to premature wear and failure." 

Writing for The Hill, Andre Zollinger, senior policy manager at J-PAL Global, makes the case that “current attention to air pollution can be transformational for how we tackle climate change. Policy leaders in the U.S. and abroad should seize this moment of reckoning over our common struggle for clean air as an opportunity to focus on policies that are known to curb air pollution and simultaneously combat climate change.”

MIT researchers have developed a new satellite observation technique that can gauge how fast rivers flowed on Mars billions of years ago and how fast they currently flow on Titan, Saturn’s largest moon, reports Talia Lissauer for The Boston Globe. “We can use these other worlds to help us understand what keeps planetary climate stable, or in some cases, what allows planetary climate to change really drastically over time like on Mars,” says Prof. Taylor Perron.

Researchers from MIT have developed a new satellite observation technique that can help gauge the strength of ancient rivers on Mars and active liquid methane rivers on Titan, Saturn’s largest moon, reports Jamie Carter for Forbes. “What’s exciting about Titan is that it’s active, and on Mars, it gives us a time machine, to take the rivers that are dead now and get a sense of what they were like when they were actively flowing,” says Prof. Taylor Perron. “With this technique, we have a method to make real predictions for a place where we won’t get more data for a long time.”

Using a new satellite observation technique, researchers from MIT and elsewhere have determined the flow of dried-up rivers on Mars and currently active liquid methane rivers on Titan, Saturn’s largest moon. “Both kinds are of scientific interest because they could reveal the role rivers play in shaping the worlds’ environments,” reports Isaac Schultz for Gizmodo.

MIT researchers have developed a new compact, lightweight design for a 1-megawatt electrical motor that “could open the door to electrifying much larger aircraft,” reports Ed Gent for IEEE Spectrum. “The majority of CO₂ is produced by twin and single-aisle aircraft which require large amounts of power and onboard energy, thus megawatt-class electrical machines are needed to power commercial airliners,” says Prof. Zoltán Spakovszky. “Realizing such machines at 1 MW is a key stepping stone to larger machines and power levels.”

MIT researchers have developed a low-cost air quality sensor that can be 3-D printed using open-source instructions and used by people around the world, reports Kristin Toussaint for Fast Company. “The reason we started this project was because we wanted to democratize environmental data,” explains research scientist Simone Mora. “We’re not just opening the data we’ve collected so far, but we hope to funnel a huge development in terms of sensors deployed in the streets, and in turn [make] the data collected available to everyone.”

Visiting scientist Judah Cohen speaks with Boston.com reporter Eli Curwin about how a combination of more accurate data collection, precise weather models, and accessible forecast predictions make it unlikely that Massachusetts residents would be surprised again by a storm like the infamous Blizzard of ‘78. “The satellites, the ships, the weather stations, weather balloons used to integrate and assimilate all that data are much better than they used to be,” says Cohen.

Forbes reporter Jeff McMahon spotlights visiting scientist Judah Cohen for his research examining the connection between Arctic snow cover and sea ice to cold air intrusions in the United States during the month of February. “December has certainly been warming if you look at the U.S.,” sayscCohen. But “February, going back to 1979—so quite a few years now—we're actually seeing in the center of the U.S. a very distinctive cooling trend.”

Boston Globe reporter Scott Kirsner spotlights Boston as a potential leader in climate technology for their “incubator spaces like Greentown Labs in Somerville and The Engine in Cambridge.”

Prof. Steven Barrett speaks with New York Times reporter Paige McClanahan about the pressing need to make air travel more sustainable and his research exploring the impact of contrails on the planet’s temperature. “Eliminating contrails is quite a big lever on mitigating the climate impact of aviation,” said Barrett.

A new study by MIT scientists finds that Earth can self-regulate its temperature thanks to a stabilizing feedback mechanism that works over hundreds of thousands of years, reports Troy Farah for Salon. “The finding has big implications for our understanding of the past, but also how global heating is shaping the future of our home world,” writes Farah. “It even helps us better understand the evolution of planetary temperatures that can make the search for alien-inhabited exoplanets more fruitful.”
