A team including MIT research scientist Ulrich Faul has discovered that the Earth’s interior contains 1,000 times more diamonds than was previously thought, writes Sarah Emerson for Motherboard. The researchers believe that one to two percent of “craton roots,” which are the deepest sections of the “rock layers extending upwards of 200 miles through the Earth’s crust and mantle,” may contain diamonds.
MIT researchers have discovered a cache of diamonds below the surface of the Earth, deeper than any drilling expedition has ventured, reports the Agence France-Presse wire. This discovery was made after “scientists were puzzled by observations that sound waves would speed up significantly when passing through the roots of ancient cratons.”
A team led by MIT research scientist Ulrich Faul ‘discovered a gigantic cache of diamonds deep beneath the Earth’s surface,’ writes Avery Thompson for Popular Mechanics. While the diamonds are too deep to be mined, “knowing that they’re there helps us learn more about our own planet and what it’s made of,” Thompson notes.
In an article for Salon, Associate Prof. Noelle Eckley Selin and postdoc Sae Yun Kwon discuss their latest research, which examined emissions in China. They write that although mercury pollution is often associated with fish consumption, “China’s future emissions trajectory can have a measurable influence on the country’s rice methylmercury” levels, as well.
CNN’s Sophie Tatum reports that six scientists from the U.S., including a senior research scientist with MIT’s Joint Program on the Science and Policy of Global Change, will join France’s new climate change initiative. The effort, notes Tatum, is meant to offer the international scientific community a chance to, “increase its efforts in battling climate change.”
Using several comparative models, a new study led by MIT researchers reveals that China’s pledge to peak its carbon emissions by 2030 could cut down on as many as 160,000 premature deaths. “Politically, the research confirms why Chinese officials have their own internal reasons to cut CO2 even though the U.S. is abandoning Paris and disengaging internationally on climate,” writes Ben Geman for Axios.
A new study finds that a 4% reduction in China's carbon emissions by 2030 could save a total of $464.5 billion in healthcare costs, writes Chase Purdy for Quartz. “We have all these policy goals for a transition toward a more sustainable society,” says Associate Prof. Noelle Selin. “Mitigating air pollution, a leading cause of death, is one of them, and avoiding dangerous climate change is another.”
Writing in The Boston Globe, Elise Takahama describes new research by MIT’s Sukrit Ranjan and colleagues that suggests sulfudic anion molecules provide evidence for the origins of life. Takahama also highlights the varying disciplines in the research team, which joined molecular chemistry experts with planetary scientists. “One of the most exciting things,” says Ranjan, is “how different communities, when they talk to each other, can really make dramatic advances.”
A study by MIT researchers examines molecules present in the early atmosphere to better understand how living things came into existence, reports David Grossman of Popular Mechanics. “Preliminary work by the researchers show that sulfidic anions would likely have quickened the chemical reactions required to convert extremely basic prebiotic molecules into RNA,” explains Grossman.
Los Angeles Times writer Amina Khan examines the planets that surround dwarf star TRAPPIST-1 – highlighting that most planets near earth’s size are likely to be rocky. “It will be really fascinating when we get to dive into the atmosphere of each of these planets and see how different or similar they are," said postdoc Julien de Wit.
Prof. Susan Solomon has been named one of two recipients of this year’s Crafoord Prize for her contributions to climate research, according to the Associated Press. Solomon was honored for her, "fundamental contributions to understanding the role of atmospheric trace gases in Earth's climate system."
A study by Prof. Daniel Rothman shows that there could be enough carbon in the Earth’s oceans by 2100 to trigger a sixth mass extinction, reports Mark Fischetti and Jen Christiansen for Scientific American.
National Geographic reporter Christina Nunez writes that MIT researchers have found that the total solar eclipse in August 2017 caused boat-like ripples in the Earth’s atmosphere. The researchers explained that the findings reveal, “complex interconnections between the sun, moon, and Earth's neutral atmosphere and ionosphere.”
In an article for The Wall Street Journal, Christopher Matthews highlights a new study by Prof. Kerry Emanuel that shows Texas faces an increased risk of devastating rainfall due to climate change. The study demonstrated how greenhouse gas emissions, “help warm offshore waters—a phenomenon that can magnify the severity of storms and generate more rain, creating bigger floods.”
A recent study from Prof. Kerry Emanuel suggests that, due to climate change, “massive hurricanes like Harvey are expected to strike Houston and Texas with much greater frequency in the future than they do now,” writes Deborah Netburn for the Los Angeles Times.
