In a private teleconference from the International Space Station, Brown alumna and NASA astronaut Jessica Meir answered students’ questions about space exploration and the path that led her to explore the stars.
The 2026 El Niño is predicted to be the strongest on record. Professor Emanuele Di Lorenzo commented on this update, comparing how different environmental factors influence a more extreme El Niño. “Deep convection switches on above a threshold sea surface temperature,” Di Lorenzo said. “The same anomaly added to a warmer mean state pushes a much larger area past that threshold and drives a stronger atmospheric response.”
A recent study estimate that Mercury is shrinking 30 percent faster than expected. “Every planet is an odd little duck that has a story to tell,” commented Assistant Professor Sam Birch, who was not involved in the study. “If you can understand how fast Mercury is shrinking, you can understand how fast it’s cooling, what size it started at and what it’s made out of.”
A 1000-year archive preserved in fossil corals from the Galápagos offers some of the strongest evidence yet that global warming is already making El Niño stronger. DEEPS Professor and IBES Director Kim Cobb commented on this new research, saying “This system is the largest source of climate extremes on our planet,” Cobb says. “And if it is in itself becoming more extreme, that has some very serious implications for society, and it’s information that we should be acting on.”
Using tracking data from the Mars Global Surveyor (MGS), Mars Odyssey (ODY) and Mars Reconnaissance Orbiter (MRO) spacecraft, a team of researchers including Postdoctoral Research Associate Nick Wagner have found that the interior of Mars’ southern hemisphere is significantly hotter than the northern half. "This temperature variation could reflect regional mantle convection or insulation by the thick southern highlands crust of Mars that has persisted over several billion years."
When the director of the Cape Verdean Museum in Rhode Island received a souvenir piece of turf from one of the tournament’s most memorable games, he knew just who to call.
A new peer-reviewed study published earlier this month in Earth’s Future suggests that it is possible to demonstrate that “emissions from company X cause injury Y.” IBES Director and DEEPS Professor Kim Cobb, an expert in observational climate studies, commented on this new study, saying we’re gaining something “extremely valuable” in Callahan’s study.
Researchers at Brown have confirmed that tiny green and orange volcanic glass beads collected during the Apollo 15 and 17 Moon missions contain trapped water, overturning the long-held belief that the lunar interior was completely dry. Professor Jim Head, who helped select the Apollo 15 landing site, commented that the water findings “absolutely revolutionized our thinking about how the Moon formed.”
From the local water quality of Narragansett Bay to river-dune interactions on Titan, DEEPS undergraduate students participated in a variety of cutting edge research projects during their 2026 summer break. We're proud to showcase their research and experiences.
The story of changing oceans is usually told through temperature shifts and melting ice, but a new study published in "Geochemistry, Geophysics, Geosystems" points to tectonic movement along the ocean floor. Professor Colleen Dalton and her team built on an earlier 2022 study that established a clear pattern of slowing global plate growth starting around 15 million years ago, which continued until about 6 million years ago. This resulted in deeper seas, and Dalton's team found that the basin deepening alone dropped sea level by 26 to 32 meters (roughly 85 to 105 feet).
In a 2025 paper in the "Journal of Geophysical Research: Planets", Assistant Professor Sam Birch and his team identified just two probable deltas among the large mapped rivers that terminate at Titan’s coastlines. That works out to roughly 1.3 per cent. Rivers of comparable size on Earth nearly always form one. The team built a numerical model to test the radar behavior of terrestrial water with the properties expected for Titan’s methane-rich liquids.
Driven to inspire future space enthusiasts, Brown University student Skye Rosario is designing and installing a new lunar science exhibit at the Museum of Natural History and Planetarium this summer.
UCF's Florida Space Institute manages the Exolith Lab, which replicates a moon-base site using simulated lunar soil to allow researchers to design and test lunar spacesuits, rovers, and exploration hardware in realistic conditions. Cecilia D’Hondt-Gorbea, a Brown University rising junior studying in DEEPS, commented on the unique experience of participating in the moon-base infrastructure practice. "...it can get warm in there quickly, which is why we take so many breaks and make sure that we're all hydrating well," D’Hondt-Gorbea said, "But it is fun."
Following the Artemis II mission, Hania Khan, a Brown Mechanical Engineering student and DEEPS Communications Assistant, sat down with Professor Jim Head to discuss the past, present, and future of the NASA lunar exploration programs, from Apollo to Artemis and beyond.
Researchers from LunaSCOPE, Brown University’s NASA-funded lunar science collaboration, have mapped the thickness of the loose dirt and rock layer that could help or hinder lunar explorers, depending on the task at hand.
Warm water in the Pacific Ocean is getting even warmer, likely to peak this winter as one of the strongest El Niño events in recorded history. Kim Cobb, Director of IBES and DEEPS Professor, spoke with NBC Connecticut about the El Niño's historical trends and recent local impact.
During the spring semester, prestigious national and international organizations recognized Brown University faculty for their leadership, service, research and scholarship.
Soaring temperatures put intense pressure on the energy grid, further strained as data centers are increasing energy demand. Many data centers rely on backup diesel generators, which release planet-warming emissions and lack air pollution controls designed to safeguard public health. Kim Cobb, DEEPS Professor and Director of IBES, commented on the relationship between higher temperatures and higher electricity demands, saying, “Even a modest increase in baseline temperature causes an exponential increase in heat extremes. You find yourself crossing these heat extremes much more frequently.”
With the 250th anniversary of the Declaration of Independence this year, fireworks will soon light up American skies. Professor Meredith Hastings, DEEPS Chair and leader of the Breathe Providence Project, joined the Possibly Podcast to talk about fireworks and their impact on the environment and our health.
Following two powerful earthquakes that recently shook northern Venezuela, rescue teams have been racing to pull survivors from the rubble. For those trapped, experts say that survival depends on many factors, including weather and access to water and air. DEEPS Professor Victor Tsai commented on the factors that affect earthquake survival, noting that trapped victims are more likely to survive if they're able to wait in a debris-free pocked, called a "survivable void space."
Researchers at Brown have shown the first direct evidence for a massive geologic uplift of the entire Aleutian Island archipelago driven by a rotation of the Pacific tectonic plate.
Following the DEM's two-year Air Toxic Study, South Providence residents are advocating for a plan to address the air pollution in the area. Professor Meredith Hastings, the Breathe Providence project leader, commented on the air quality, saying, "We know there’s a lot of bad stuff in the air. Sometimes it’s illegal. It’s definitely cancer-causing.” Linda Perri, head of the Washington Park Neighborhood Association, told City Council members and planners, “We need to have a say in how the growth is going to happen, especially because we breathe the air and we live in the shadow of the port.”
Following a milestone 75% decrease in greenhouse gas emissions, the University will establish a new campus heating network that reduces emissions and dramatically increases efficiency and resiliency.
