UT San Antonio astronomy professor awarded for advancements in planetary science

Xinting Yu, assistant professor in the Department of Physics and Astronomy at The University of Texas at San Antonio, is one of two recipients of the 2025 Harold C. Urey Prize.

(Press-News.org) Xinting Yu, assistant professor in the Department of Physics and Astronomy at The University of Texas at San Antonio, is one of two recipients of the 2025 Harold C. Urey Prize.

The national award from the American Astronomical Society’s Division for Planetary Sciences recognizes early-career scientists shaping the future of space research.

Yu was honored for her research in planetary and exoplanetary science — the study of planets in our solar system and beyond. Her work focuses on how planetary surfaces and atmospheres interact and evolve.

By combining lab experiments with computer modeling, Yu is helping scientists better understand phenomena ranging from windblown dunes on Saturn’s moon Titan to the thick clouds enveloping distant exoplanets.

Yu’s lab studies unusual planetary materials, like icy particles and haze, to understand their behavior in extreme environments. Her team has published more than 15 papers in top journals and been featured in national science media.

Mini-Neptunes One of her most memorable research discoveries happened in 2021, Yu said, when she predicted atmospheric compositions of exoplanets measurable by the James Webb Space Telescope (JWST) could help scientists distinguish “mini-Neptunes” from “super-Earths.” The intermediate-sized planets, the most abundantly discovered so far, don’t exist in our solar system and little is known about them.

“It’s really important to know whether some of these planets could have surface conditions like Earth so we can expand our search for habitable worlds beyond Earth-sized planets,” Yu said.

The space telescope can’t directly observe the planets’ surfaces, so Yu’s method uses atmospheric data to probe them indirectly. Now that the telescope has begun collecting data, her approach is being applied in ongoing research to interpret observations of several exoplanets outside of our solar system that are the strongest candidates for harboring life.

As part of Yu’s research group, UTSA graduate student Cindy Luu recently published a 2024 study describing K2-18 b, a super-Earth exoplanet located outside of our solar system that is believed to be a sort of water world with a supercritical water ocean.

This work applied Yu’s atmospheric analysis methods to offer insights that could reshape how scientists view sub-Neptune worlds, further advancing the lab’s mission to understand distant exoplanets.

Magic islands In 2024, Yu made headlines with her research on Titan’s mysterious “magic islands” — bright patches that appear and disappear in its methane seas. Her research suggests they are clumps of floating organic material, like icebergs, and proposes a thin frozen layer may coat Titan’s lakes, explaining their smooth appearance.

Currently, Yu is leading a project studying “missing” methane gases in warm-to-hot exoplanet atmospheres. Her team developed a fast, geochemistry-inspired framework suggesting these planets may have hotter interiors than models predict, showing how atmospheric chemistry probes planetary interiors.

The professor is also developing ways to determine if distant planets have solid or liquid surfaces using atmospheric data, inspired by Titan and Jupiter’s contrasting atmospheres. This could help identify potentially habitable worlds using JWST data.

How planets form Yu’s research team is expanding into planet formation research and aims to use her lab’s Planetary Material Characterization Facility (PMCHEF) to study early solar system materials. Besides analyzing carbon-rich meteorite samples they already possess, the team hopes to study samples from asteroid Bennu and a future NASA comet sample-return mission.

“This would help us address multiple open questions in the field, such as how elements go into forming planets and how planets form from very tiny dust particles,” Yu said.

Before joining the university in 2023, Yu was a postdoctoral fellow at the University of California, Santa Cruz through the 51 Pegasi b Fellowship.

In her first year at UT San Antonio, she launched the Texas Area Planetary Science (TAPS) Meeting to foster local collaboration among planetary and exoplanet scientists. In 2023, she also received NASA’s Planetary Science Early Career Award, which helped establish her lab, PMCHEF.

With her research and leadership, Yu is helping UTSA grow its planetary science discovery effort and expand understanding of worlds near and far.

‘Internal alarm system’ harnesses immune system against cancer

2025-09-16
Scientists have developed a smarter way to activate the immune system against cancer, potentially making treatments safer and more precise. The research focuses on a powerful pathway inside our cells known as STING. When triggered, STING acts like an internal alarm system, sending out signals that summon the body’s immune system to attack. Drugs that activate this pathway have shown promise in cancer therapy, but until now, they faced a major problem: if switched on in healthy tissues, they can cause harmful and sometimes dangerous side effects. To solve this problem, researchers from the University of Cambridge designed a two-part ‘prodrug’ ...

Stem cell transplant for stroke leads to brain cell growth and functional recovery in mice

2025-09-16
When someone has a stroke — a leading worldwide cause of death and disability — time is of the essence. Almost nine out of 10 cases are ischemic strokes, caused by restricted blood flow in the brain, and the current gold-standard treatment that breaks up blood clots must be delivered within four and a half hours of symptoms appearing.  Researchers are on the hunt for ways to extend that ticking clock and enable better stroke recovery. One promising prospect is an experimental stem cell therapy to help repair damaged brain tissue, co-developed by scientists at the Keck School of Medicine of USC, the University of ...

Cleveland Clinic study shows greater long-term benefits of bariatric surgery compared to GLP-1 medicines

2025-09-16
UNDER EMBARGO Tuesday, September 16, 2025, 05:00 a.m. ET, CLEVELAND: A large Cleveland Clinic study has found that people with obesity and type 2 diabetes who undergo weight-loss surgery live longer and face fewer serious health problems compared with those treated with GLP-1 receptor agonist medicines alone.   Patients who had weight-loss surgery (also known as bariatric or metabolic surgery) lost more weight, achieved better blood sugar control, and relied less on diabetes and heart medications over 10 years. The research is published ...

Ancient crop discovered in the Canary Islands thanks to archaeological DNA

2025-09-16
The lentils now grown in the Canary Islands have a history that stretches back almost 2,000 years on the site. This is shown in the very first genetic study of archaeological lentils, carried out by researchers at Linköping University and the University of Las Palmas de Gran Canaria in Spain. Since these lentils have been adapted for cultivation in hot and dry climates for a very long time, they may become valuable for plant breeding in the light of ongoing climate change. Over a thousand years ago, the indigenous people of the island of Gran Canaria used long-term storage to preserve their harvest. They dug out grain silos ...

Mapping the Universe, faster and with the same accuracy

2025-09-16
If you think a galaxy is big, compare it to the size of the Universe: it’s just a tiny dot which, together with a huge number of other tiny dots, forms clusters that aggregate into superclusters, which in turn weave into filaments threaded with voids—an immense 3D skeleton of our Universe. If that gives you vertigo and you’re wondering how one can understand or even “see” something so vast, the answer is: it isn’t easy. Scientists combine the physics of the Universe with data from astronomical instruments and build theoretical models, such as EFTofLSS (Effective Field Theory of Large-Scale Structure). ...

Designing a sulfur vacancy redox disruptor for photothermoelectric and cascade‑catalytic‑driven cuproptosis–ferroptosis–apoptosis therapy

2025-09-16
As cancer evolves, the demand for intelligent therapeutics that integrate energy conversion, metabolic interference, and immune activation intensifies. Now, researchers from Harbin Engineering University and Harbin Normal University, led by Professor Piaoping Yang, Professor Lili Feng, and Professor Wei Guo, have delivered a comprehensive study on biodegradable Cu2MnS3-x-PEG/glucose oxidase (MCPG) nanosheets that realize triple-modal cell death. This work offers a blueprint for next-generation nanotherapies that break the “resistance ceiling” of single-mechanism treatments.
