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.”
Wired reporter Sian Bradley writes that a study co-authored by MIT researchers shows that the world’s largest mass-extinction was triggered by a massive underground magma pulse. The magma pulse “released dangerous levels of carbon dioxide, methane and sulphur dioxide into the environment and triggered the end of the Permian period.”
Boston Globe reporter Alex Kingsbury writes that a new study by MIT researchers shows that Indian monsoons have been getting stronger over the past 15 years. Kingsbury explains that the findings, “came as quite a surprise: Since the 1950s, conventional wisdom has been that India was drying up.”
MIT researchers have found that by 2050 climate change could deplete water basins and reduce crop yields, reports The Boston Globe’s Alyssa Meyers. If no action is taken to combat climate change, “numerous basins used to irrigate crops across the country will either start to experience shortages or see existing shortages ‘severely accentuated.’”
MIT researchers have developed a laser sensing technique that can decipher the makeup of space debris orbiting around Earth, reports Alex Kingsbury for The Boston Globe. Knowing what material the debris is made of, “will allow for more precise calculations of momentum, velocity, and the danger they may pose to other objects aloft in orbit,” explains Kingsbury.
MIT was named the top university in the world for the sixth consecutive year in the QS World University Rankings, reports Kyle Scott Clauss for Boston Magazine.
In an article for Scientific American, Laura Geggel writes that a new study by MIT researchers shows that the Earth’s mantle is hotter than previously thought. “The finding will help scientists more accurately model Earth's many geodynamic processes, including plate tectonics,” reports Geggel.
Writing for The Washington Post, Prof. Maria Zuber, MIT’s vice president for research, outlines how the U.S. can reduce coal emissions without “declaring war on coal communities.” Zuber argues that the U.S. must “commit to helping the workers and communities that are hurt when coal mines and coal plants reduce their operations or shut down.”
Prof. Sara Seager speaks with WGBH’s Edgar Herwick about the search for life on other planets, following the discovery of seven Earth-sized exoplanets. "The first thing we’re gonna look for is water vapor in the atmosphere," Seager explains. “If there’s water, we want to look and see if there are gasses that don’t belong that might be produced by life."
Postdoc Julien de Wit speaks with Boston Herald reporter Marie Szaniszlo about the discovery of seven Earth-like planets. De Wit, who is leading the effort to study the planets’ atmospheres, explains that “this is the first time that we’ve found so many small planets — each potentially habitable — around the same star, a star that’s close to us.”
Postdoc Julien de Wit speaks with NPR reporter Nell Greenfieldboyce about the discovery of seven exoplanets that could harbor the conditions necessary to sustain liquid water. Greenfieldboyce reports that de Wit explained that the planets have a “‘winning combination’ of being temperate, Earth-size and ideally suited for follow-up observations with telescopes to analyze their atmospheres.”
An international team of scientists, including astronomers from MIT, has discovered seven Earth-sized planets, reports Sarah Kaplan for The Washington Post. Julien de Wit, a postdoc at MIT who is leading the study of the planets’ atmospheres, explains that repeated observations of the planets, “lifted the veil on the architecture of the system.”
