New radiometric dating of material returned from the Moon suggests there was active volcanism 120 million years ago – nearly 2 billion years more recently than previous estimates. Assistant Professor James Dottin III shared his perspective, unconvinced that the three beads are conclusively volcanic.
Pieces of the asteroid Bennu, collected by NASA’s OSIRIS-REx mission, are being studied at Brown as part of an effort to better understand the solar system’s early history and the origins of materials necessary for life on Earth.
Kim Cobb, a professor of earth, environmental and planetary sciences and Director of the Institute at Brown for Environment and Society, delivered the Family Weekend keynote about the inflection point at which the world finds itself — and the numerous ways that the current generation of students is rising to face critical climate challenges through research and action. “I am extremely optimistic, mostly because the work that we’re doing here at Brown is illustrative of the engagement of this institution, and our entire community in making solutions that are durable and equitable,” Cobb said.
In a recent study published in Nature Communications Earth & Environment, OCE High School Interns working with Professor Emanuele Di Lorenzo found that marine heatwaves in the Gulf of Alaska have intensified since 2013, disrupting ocean currents known as eddies, which support marine life. Using 30 years of satellite data and climate models, the team examined how these heatwaves affect nutrient-rich ocean currents called eddies, which support phytoplankton. The study revealed that marine heatwaves create high-pressure conditions that weaken coastal circulation, reducing the formation of eddies and threatening marine life.
A recent publication in Science by Andrea Tokranov, Class of 2012, presents a national predictive model for assessing the level of "forever chemicals" (PFAS) in groundwater at the depths of drinking-water supplies across the United States. The study suggests that up to 95 million people may unknowingly rely on groundwater contaminated with PFAS. Since PFAS analysis is costly, the model aims to help direct resources to high-risk areas.
According to new research published in the Proceedings of the National Academy of Sciences, conducted during three research cruises from 2017 to 2019 in the Mediterranean Sea, scientists discovered that tiny ocean organisms are transported to deeper waters by currents called intrusions, significantly impacting the ocean's ecosystem. “We found that because these organisms are so small, they can be swept up by ocean currents that then bring them deeper than where they grow,” said Assistant Professor Mara Freilich. “It’s often a one-way trip for these organisms, but by taking this trip, they play a critical role in connecting different parts of the ocean.”
This week, the eleventh session of the World Meteorological Organization (WMO) Research Board considered critical developments in Artificial Intelligence for weather forecasting under the leadership of Board Chair Professor Amanda Lynch.
NASA has announced a new strategy review team, including DEEPS Professor Jack Mustard, to assess potential architecture adjustments for the agency’s Mars Sample Return Program. The program aims to bring back scientifically selected samples from Mars, and is a key step in NASA’s quest to better understand our solar system and help answer whether we are alone in the universe.
A recent Brown Daily Herald poll found that female students are less likely than their male counterparts to study the physical sciences at Brown. DEEPS Chair, Professor Meredith Hastings discussed how representation and the “leaky pipeline" contribute to this issue, and highlighted ways it is being addressed. “We definitely have seen the numbers go up across the board,” Hastings said, adding that more work is yet to be done, such as addressing exclusionary behaviors.
The Europa Clipper spacecraft lifted off from Cape Canaveral on October 14th to find out whether the icy ocean of Jupiter's moon is habitable. “We’ll be able to describe what that habitable environment is like,” says Associate Professor Ingrid Daubar, who works on Clipper for NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California.
Following the catastrophic damage caused by Hurricanes Helene and Milton, scientists warn that the Atlantic hurricane season is far from over. Assistant Professor Chris Horvat commented, “The Gulf (of Mexico) remains fairly anomalously warm even at this point in the year, so we shouldn’t relax."
IBES Director and DEEPS Professor Kim Cobb noted that Hurricanes Helene and Milton "should serve 'as a wake up call' for emergency preparedness, resilience planning and the increased use of fossil fuels."
DEEPS Assistant Professor James Dottin is featured in the latest installment of PBS's award-winning documentary series, NOVA. The five-part series premiers on October 2nd, and will focus on the solar system.
Physics Today contacted early-career faculty in the physical sciences to discuss the unexpected challenges of their new role, including securing funding, building labs, teaching, and recruiting students—often without formal training. Assistant Professor James W. Dottin shared his experience setting up his lab.
The endeavour to leverage mycotecture – called the Mycotecture Off Planet Structures at Destination project – has recently been awarded a Phase III contract with NASA, meaning it will receive the funding necessary to continue. The mycotechnology has the support of prominent NASA figures such as DEEPS Professor Jim Head, who once trained astronauts for the Apollo lunar exploration programme, and Apollo 15 commander David Scott.
This summer, DEEPS Assistant Professor Emily H. G. Cooperdock, graduate student Anahi Carrera, and Columbia University Professor Steven L. Goldstein visited the island of Unalaska to collect samples that will help interpret data from a 2015 NSF GeoPRISMS campaign, as well as pave the way for future research.
Inspired by Chinese handscrolls and NASA film of the moon’s surface, senior Logan Tullai used an 1800s technique to lead a community art project on campus on 60-foot-long swaths of silk.
From U.S. News and World Report to Forbes and Princeton Review, prominent rankings and surveys in the last year gave Brown high marks for its distinctive student experience and high-impact teaching and research.
Professor Greg Hirth has been awarded the 2024 Harry Hess Medal from the American Geophysical Union. The Harry H. Hess Medal is given annually to a senior scientist in recognition of outstanding achievements in research on the constitution and evolution of the Earth and other planets.
Each year, AGU celebrates individuals who have made significant contributions to the Earth and space sciences. This year, DEEPS graduate student Manar Al Asad was honored with the 2024 Study of the Earth's Deep Interior Section Award for Graduate Research.
A new paper published earlier this year by alumn Benjamin Boatwright PhD’22 and Professor James Head PhD’69 proposes new refinement to current imagining technologies using a method they call “shape-from-shading.”
