A study led by MIT research scientist Ulrich Faul finds that diamonds are about 1,000 times more common in the Earth than previously thought, report Ayana Archie and Ralph Ellis for CNN. “The deposits sit some 90 to 150 miles below the Earth's surface, much deeper than current mining machinery allows,” write Archie and Ellis.
By using sound waves, MIT researchers have discovered that part of Earth’s stable crust may contain diamonds, reports Abbey Interrante for Newsweek. “This shows that diamond is not perhaps this exotic mineral, but on the [geological] scale of things, it’s relatively common,” says research scientist Ulrich Faul.
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.
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.
In this video, Nicholas Cardona reports for USA Today that Prof. Daniel Rothman has predicted that the Earth’s next mass extinction event could begin in 2100, based on an analysis of the last five mass extinction events. Rothman found that, “each of the events saw high increases in global carbon. That leads to a destabilized ecosystem,” Cardona reports.
In a new study, Prof. Daniel Rothman has predicted that the oceans may hold enough carbon to trigger a sixth mass extinction by 2100, reports Trevor Nace for Forbes. Rothman’s analysis showed that, “given the current rate of carbon being emitted into the atmosphere, we will likely reach a mass extinction threshold by the year 2100.”
HuffPost reporter Thomas Tamblyn writes that Prof. Daniel Rothman has analyzed the Earth’s five previous mass extinctions and found that a sixth could be triggered by 2100. Rothman found that, “if a certain amount of carbon dioxide was added to the oceans on top of its existing levels it would result in a sixth mass extinction event.”
A new study by Prof. Daniel Rothman provides evidence that by 2100 the world’s oceans may hold enough carbon to trigger a sixth mass extinction, reports Alyssa Meyers for The Boston Globe. Rothman found that if, “310 gigatons of carbon dioxide are added to the oceans, it could be a crucial tipping point for the carbon cycle.”
An MIT study finds that the Earth’s mantle was 200 degrees Celsius hotter three billion years ago than it is today. That finding shows “that the Earth's ancient crust was made up of a much denser, iron- and magnesium-enriched material than today's rocky mantle,” writes Amy Wallace for UPI.
A study co-authored by MIT researchers shows that the moon’s magnetic field could have lasted for as long as two billion years, according to Xinhua. “The researchers are planning to analyze more lunar rocks to determine when the dynamo died off completely.”
MIT researchers have found that the moon’s magnetic field lasted at least 1 billion years longer than initially thought, reports Charles Q. Choi for NBC News. “Understanding more about the nature of the magnetic field of Earth's moon could shed light on the magnetic fields of distant moons and planets, which could influence their habitability."
By examining a lunar rock from the Apollo 15 mission, researchers from MIT and Rutgers University have found that the moon had a magnetic field for at least one billion years longer than initially thought, reports Nicola Davis for The Guardian. The researchers found that the, “lunar dynamo was still going until somewhere between one billion and 2.5bn years ago.”
Boston Globe reporter Martin Finucane writes that a new study co-authored by MIT researchers provides evidence that the moon’s magnetic field lasted 1 billion years longer than previously thought. “Researchers now believe the moon’s magnetic field existed for a total of at least 2 billion years,” Finucane explains.
A new study co-authored by MIT researchers finds that underground magma triggered the world’s largest mass extinction, reports Howard Lee for The Guardian. Based off their findings, the researchers believe that, “greenhouse gas emissions triggered by magma intrusions...caused the extinction through abrupt global warming and ocean acidification.”
