MIT engineers have developed a new system that helps pesticides adhere more effectively to plant leaves, allowing farmers to use fewer chemicals without sacrificing crop protection, reports Michigan Farm News. The new technology “adds a thin coating around droplets as they are being sprayed onto a field, increasing the stickiness of pesticides by as much as a hundredfold.”
Researchers at MIT have discovered how “greenhouse gases are impacting Earth’s upper atmosphere and, in turn, the objects orbiting within it,” reports Grace Snelling for Fast Company. “If we don’t take action to be more responsible for operating our satellites, the impact is that there are going to be entire regions of low Earth orbit that could become uninhabitable for a satellite,” says graduate student William Parker.
MIT researchers have discovered that increased greenhouse gas emissions in the Earth’s upper atmosphere can “potentially cause catastrophic satellite collision in low-Earth orbit,” reports Bruce Dorminey for Forbes. “When the thermosphere contracts, the decreasing density reduces atmospheric drag — a force that pulls old satellites and other debris down to altitudes where they will encounter air molecules and burn up,” Dorminey explains. “Less drag therefore means extended lifetimes for space junk, which will litter sought-after regions for decades and increase the potential for collisions in orbit.”
MIT researchers have found that high levels of greenhouse gas emissions in the atmosphere may increase the risk of satellite collisions, reports Sachi Kitajima Mulkey for Grist. “The environment is very cluttered already. Satellites are constantly dodging right and left,” says graduate student William Parker. “As long as we are emitting greenhouse gases, we are increasing the probability that we see more collision events between objects in space.”
Associated Press reporter Seth Borenstein writes that MIT scientists have found that climate change could “reduce the available space for satellites in low Earth orbit by anywhere from one-third to 82% by the end of the century, depending on how much carbon pollution is spewed.” Graduate student William Parker explains: “We rely on the atmosphere to clean up our debris. There’s no other way to remove debris. It’s trash. It’s garbage. And there are millions of pieces of it.”
A new study by MIT researchers finds that “climate change could threaten the future use of satellites and significantly reduce the number of spacecraft that can safety orbit Earth,” reports Julia Jacobo for ABC News. The researchers found “global warming is causing space debris to linger above the planet for longer periods of time, leaving less space for functioning satellites and posing a growing problem for the long-term use of Earth’s orbital space,” Jacobo explains. “Reducing greenhouse gas emissions doesn't just help us on Earth, it also has the potential to protect us from long-term sustainability issues in space,” explains graduate student William Parker.
A study by MIT scientists has found that increased greenhouse gas emissions will shrink the Earth’s upper atmosphere causing a “drop in the satellite-carrying capacity of low Earth orbit,” repots Passant Rabie for Gizmodo. “Without an atmosphere, most space debris would remain in orbit indefinitely,” Parker said. “As the atmosphere thins, debris lingers longer, increasing the risk to active satellites. With the growing consequences of space debris, we can accommodate fewer debris-generating events.”
Researchers at MIT have found that climate change could raise the risk of satellite collisions, reports Justine Calma for The Verge. “We’ve really reached the end of that era of ‘space is big,’ and I think we should stop saying that,” says graduate student, William Parker. “People don’t realize that the space sustainability issue is really an issue that impacts them directly.”
David Zipper, a senior fellow at the Mobility Initiative, speaks with WBUR Here & Now co-host Scott Tong about “car bloat,” the trend of increasingly large SUVs and trucks on the road. “I personally believe that car bloat is a major public health issue, it's a major policy issue, but I'll be candid, I don't think the average American does right now,” explains Zipper. “We need people to understand it and appreciate it. And in my view, that's going to need to happen at the grassroots level before we can expect really anybody in Washington to address this problem in the way that it deserves to be addressed.”
Lincoln Lab Senior Scientist Vijay Gadepally speaks with Washington Post reporter Nicolas Rivero about ways to make AI more sustainable. “Whatever we do, energy usage is likely going to go up,” says Gadepally. “That train has left the station.”
Georgina Campbell Flatter SM '11 has been named the chief executive of Greentown Labs, the “nation’s largest clean-tech incubator,” reports Jon Chesto for The Boston Globe. “This is a pretty critical time for energy and climate, and we all need to lean in,” says Flatter.
Prof. Desirée Plata speaks with C&EN reporter Prachi Patel about her work “trying to make our chemical processes and industries compatible with human and ecological health.” Says Plata of what she is most proud of in her work: “As professors, we produce papers and patents, but people are the most important thing we produce. The faculty of the world are training the next generation of researchers. There’s a perception right now that AI is going to solve all of our problems, but it cannot without good physical science information. We need a trained workforce. We need patient chemists who want to solve important problems.”
Writing for The Hill, Prof. Emeritus Henry Jacoby and his colleagues highlight implications of climate change denial on a global scale. “Denying there is a problem stimies efforts to correct the damaged insurance system, organize disaster relief appropriate for changing threats, and properly inform decisions about protective investment,” they write. “Besides the urgent need to protect programs to limit U.S. greenhouse gas emissions, and to bring the nation back into the global effort, the federal administration and recalcitrant state leaders must be convinced to pull their heads out of the dirt and face the change that is coming — whether they want to acknowledge it or not.”
Newsweek reporter Tom Howarth spotlights MIT spinout Commonwealth Fusion Systems as they announced plans to “build the world's first grid-scale commercial nuclear fusion power plant” in Virginia. “The plant is expected to generate 400 megawatts of electricity, enough to power approximately 150,000 homes or large industrial facilities,” writes Howarth.
Commonwealth Fusion Systems, an MIT spinoff, plans to build “the nation’s first grid-scale fusion power plant in Virginia by the early 2030s,” reports Laura Vozzella and Gregory S. Schneider for The Washington Post. “Fusion is a long-sought source of power that can generate almost limitless energy by combining atomic nuclei,” they write. “It is unlike fission, the more common form of nuclear energy, in which the nucleus is split, and which generates large amounts of radioactive waste.”
