In this video for Wired, Prof. Anne White explains the nature of nuclear fusion in five levels of increasing difficulty to a child, a teen, a college student, a grad student, and an expert. “Fusion is so exciting because it is extraordinarily beautiful physics, which underpins some of the most basic processes in our universe," says White. “Nuclear processes have a tremendously valuable application for humankind, a virtually limitless, clean, safe, carbon-free form of energy.”
Researchers from MIT’s Plasma Science and Fusion Center and Commonwealth Fusion Systems (CFS) are using high-temperature superconducting tape as a key part of the design for their tokamak reactor, reports Tom Clynes for IEEE Spectrum. The researchers believe that “this novel approach will allow it to build a high-performance tokamak that is much smaller and less expensive than would be possible with previous approaches,” Clynes notes.
MIT researchers have found that over the past two decades, the color of the world’s oceans has changed significantly, reports Talib Visram for Fast Company. The change “is likely due to human-induced climate change,” explains Visram. “The color shifts matter in that they signal changes in ecosystem balance, which have the power to disrupt fragile marine food webs.”
CNN reporter Jack Guy spotlights a new study co-authored by researchers at MIT, which shows that the ocean’s color has changed considerably over the last 20 years and human-caused climate change is likely responsible. “All changes are causing an imbalance in the natural organization of ecosystems,” says senior research scientist Stephanie Dutkiewicz. “Such imbalance will only get worse over time if our oceans keep heating.”
Researchers at MIT and elsewhere have discovered that the ocean’s hue has changed significantly over the last 20 years, reports Laura Baisas for Popular Science. “A shift in ocean color is an indication that ecosystems within the surface may also be changing,” writes Baisas. “While the team can’t point to exactly how marine ecosystems are changing to reflect the shift, they are quite sure that human-induced climate change is likely behind it.”
A new study led by a team including researchers at MIT has found that more than half of the world’s ocean has changed color in the last 20 years, reports Coco Liu for Bloomberg. “The color shift could be caused by changes in plankton communities that are critical to the marine food chain,” writes Liu. “And biodiversity isn’t the only thing at stake: The shift could also affect how much carbon dioxide the ocean takes up, since different types of plankton have different abilities to absorb it."
Sublime Systems, a startup founded by Prof. Yet-Ming Chiang and former MIT postdoc Leah Ellis, is working to decarbonize cement making – a process which currently accounts for eight percent of global carbon emissions. “The world has a huge appetite for cement, and Sublime is working to scale its production to meet it,” writes Casey Crownhart for The Spark, MIT Technology Review’s weekly climate newsletter.
Sergey Paltsev, deputy director of the MIT Joint Program on the Science and Policy of Global Change, speaks with WCVB-TV about the pressing need for action to address the climate crisis, following the Earth’s hottest days on record. Paltsev emphasized that he hopes the record-shattering heat will motivate policymakers and the general public to take action to prevent extreme climate events in the future.
Writing for the Financial Times, Prof. Robert Pindyck makes the case that households, private businesses and governments must "invest in adaptation to climate change, in order to counter its possible impact.” Pindyck writes, “Now is the time to put more effort into efficient CO₂ emission reduction, and invest in adaptation to limit the impacts of climate change.”
Researchers from MIT and elsewhere have found that new building codes put in place to combat climate change could impact home affordability in the greater Boston area, reports Paula Ebben for CBS Boston, “If widely adopted, [the codes] could add up to $23,000 to the cost of an average home, leaving an additional 33,000 Massachusetts residents priced out of the market,” writes Ebben.
Randolph Kirchain and Hessam AzariJafari of the MIT Concrete Sustainability Hub speak with Washington Post reporter Sharon Osaka about the importance of reducing the emissions produced during the cement manufacturing process. Kirchain noted there is a way to cut carbon emissions significantly and ensure safety at the same time. “The things that concrete goes into are things that we need to last,” he said.
A study from MIT and elsewhere has found that a new building code in Massachusetts designed to promote “net zero” development, “would increase construction costs and potentially worsen the state’s housing crisis,” reports Greg Ryan for NBC Boston.
Prof. Yet-Ming Chiang co-founded Sublime Systems, a company that has developed a new method for producing cement that is powered by electrochemistry instead of fossil fuel-powered heat, reports Catherine Clifford for CNBC. “I believe climate change has pushed all of us into an extremely fertile, creative period that will be looked back on as a true renaissance,” says Chiang. “After all, we're trying to re-invent the technological tools of the industrial revolution. There's no shortage of great problems to work on! And time is short.”
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.”
