Researchers at MIT have uncovered remnants of “proto Earth,” which existed before a Mars-sized meteorite slammed into the Earth billions of years ago, reports Gayoung Lee for Gizmodo. The researchers “found an odd imbalance of potassium isotopes in ancient rock samples,” explains Lee. “Chemical analyses revealed the anomaly couldn’t have emerged from any known geological processes on modern Earth.”
New York Times reporter Annabel Keenan highlights the “Remembering the Future” exhibit at the MIT Museum, a sculptural installation created by Janet Echelman that uses “climate data from the last ice age to the present, as well as projected future environments, to create a geometric design.” Echelman worked with MIT faculty, including Prof. Raffaele Ferrari and Prof. Caitlin Mueller, to bring the project to life. Mueller explains that she developed a “high-fidelity digital twin of the sculpture generated through our computational simulation that you can orbit and pan through to get perspectives that you can’t see physically in the space.”
Using molecular evidence buried in rocks, researchers at MIT suggest that some of the Earth’s first living creatures are ancestors of the modern sea sponge, reports Ashley Fike for Vice. “The discovery suggests the earliest animals were simple, filter-feeding organisms that slowly cleaned the seas while the rest of the evolution was still figuring itself out,” says Fike. “These early sponges likely had no skeletons, nerves, or eyes – just porous bodies that absorbed water and nutrients. Yet they paved the way for everything that came next, from insects to mammals to us.”
A new study by MIT researchers suggests sea sponges may have been the “first animals to inhabit the Earth,” reports Maria Azzura Volpe for Newsweek. “In their work, the researchers linked so-called ‘chemical fossils’ found in ancient rocks to the ancestors of a class of modern-day sea sponges known as demosponges,” explains Volpe. “These chemical fossils—the molecular remnants of once-living organisms that have been buried, transformed, and preserved in sediment over time—were discovered in rocks that date back to more than 541 million years ago, during the Ediacaran Period.”
MIT researchers have uncovered new evidence that suggests some of Earth’s first living creatures are ancestors of the modern sea sponge, reports Andrew Paul for Popular Science. The researchers identified 541 million-year-old chemical fossils embedded in sediment that they believe may indicate that some of Earth’s earliest creatures were the ancient relatives of today’s sea sponges.
Researchers at MIT have found that up to 98% of the energy produced by an earthquake dissipates as heat, reports Stephanie Pappas for Scientific American, who notes that the findings could be used to help create better earthquake forecasts. The researchers “created itty-bitty lab earthquakes by pressing centimeter-sized wafers of a powdered granite and magnetic particle mixture between aluminum pistons until the wafers slipped or snapped,” explains Pappas. “They measured this process of cracking under stress with thermometers and piezoelectric sensors that mimic the seismographs used to measure real earthquakes.”
Researchers at MIT have created “a series of miniature, controlled versions of real earthquakes to see where all that destructive energy actually goes and what it’s doing,” reports Luis Prada for Vice. “The goal of the research is to isolate the key physical processes that underlie every earthquake,” explains Prada. “The hope is that any knowledge gained will help refine earthquake prediction models and possibly even pinpoint which regions are sitting on fault lines ready to pop.”
Using the James Webb Telescope, researchers at MIT and elsewhere are studying the potential presence of “an Earth-like atmosphere on an exoplanet for the first time,” reports Jacopo Prisco for CNN. “The planet is part of a planetary system about 40 light-years away from Earth called TRAPPIST-1,” explains Prisco.
Gizmodo reporter Gayoung Lee writes that MIT researchers created “lab quakes” or miniature versions of earthquakes in a controlled setting and found that “anywhere between 68 and 98% of the energy goes into generating heat around a quake’s epicenter.” The findings “could help inform the creation of a physical model for earthquake dynamics or seismologists’ efforts to pick out regions most vulnerable to earthquakes.”
After observing the collision between a supernova and a black hole, researchers at MIT and elsewhere are rethinking our understanding of the life and death of stars, reports Jeanine Santucci for USA Today. "One of the only reasons that we were able to make this discovery and understand how scientifically interesting it was was through the combination of researchers in machine learning and in astrophysics," says postdoctoral scholar Alex Gagliano.
With the help of a newly designed machine learning algorithm, researchers at MIT and elsewhere have spotted a “never-before-seen type of supernova that involves a nearby black hole,” reports Andrew Paul for Popular Science. “We’re now entering an era where we can automatically catch these rare events as they happen, not just after the fact,” said postdoctoral scholar Alex Gagliano. “That means we can finally start connecting the dots between how a star lives and how it dies, and that’s incredibly exciting.”
Using an AI algorithm, researchers at MIT and elsewhere have been able to identify a previously unobserved explosion in the universe that they consider a “new flavor of supernova,” reports Kasha Patel for The Washington Post. “We think that statistically we’re overdue for a supernova in our own galaxy,” says postdoctoral scholar Alex Gagliano. “There are many people that are trying to establish early warning systems so that as soon as our telescopes pick up on something unusual, we can all aim our telescopes in that location.”
Researchers at MIT have proposed that liquids, such as ionic fluids, are “what’s important for extraterrestrial habitability, and not just water,” reports Gayoung Lee for Gizmodo. If confirmed, this research would “dramatically expand what’s considered the ‘habitable zone’ among known exoplanets,” writes Lee. “By current standards, the habitable zone is defined as the band within planetary systems in which liquid water can remain stable on the surface. When it comes to life, we’re understandably biased towards water; all life as we know it depends on it.”
Guy Consolmagno '74, SM '75, director of the Vatican Observatory, speaks with Rebecca Mead of The New Yorker about his journey from suburban Detroit to MIT to his current role as the Pope’s Astronomer, and the intersection between science and religion. “If people think you have to be a weird kind of scientist to be religious, or a weird kind of religious to be a scientist, then we’ve missed the point,” says Consolmagno. “The point is that our faith—our ordinary faith—fits perfectly with our ordinary, but wonderful, delightful science.”
Graduate student Isabella Macias speaks with CBS News about her experience studying astronomy and planetary formation at the Vatican Observatory. “The Vatican has such a deep, rich history of working with astronomers,” says Macias. “It shows that science is not only for global superpowers around the world, but it's for students, it's for humanity.” Br. Guy Consolmagno '74, SM '75, director of the Vatican Observatory, shares how he feels astronomy can help unite people around the world.
