SwRI appoints Fuselier vice president of Space Science Division

Noted solar physicist is a member of the National Academy of Sciences

2026-02-04

(Press-News.org) SAN ANTONIO — February 4, 2026 — Dr. Stephen Fuselier has been appointed as vice president of the Space Science Division of Southwest Research Institute (SwRI). A noted heliophysicist, Fuselier recently served as the co-chair of the National Academies of Solar and Space Physics Decadal Survey. NASA uses its recommendations to identify and prioritize the scientific questions and necessary observations required to answer them over the next 10 years.

“I’m thrilled to lead SwRI’s Space Science Division,” Fuselier said. “I’ve spent much of my career at the Institute, and I have tremendous respect for everyone in the division."

Fuselier earned a doctorate in physics from the University of Iowa in 1984 and has more than four decades of experience in the space science field where he has held multiple technical positions on an array of NASA missions.

“As one of the broadest-based scientists in heliophysics, Stephen is an excellent choice to lead the division,” said Dr. Jim Burch, senior vice president of SwRI’s Space Sector. “He has achieved transformational science results from the aurora in the upper atmosphere to the edge of the solar system including the Earth’s magnetosphere and bow shock, Saturn’s magnetosphere and comets.”

Fuselier has played a key role in numerous NASA missions focused on how the Sun and solar wind shape and define the heliosphere, the magnetic bubble around the solar system. He serves as a co-investigator on the Interstellar Mapping and Acceleration Probe (IMAP), sensor lead on the Interstellar Boundary Explorer (IBEX) mission and deputy principal investigator and instrument lead on the Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites (TRACERS), which launched in July 2025. He is a co-investigator of the Magnetospheric Multiscale (MMS) mission, which studies magnetic reconnection in the Earth’s magnetosphere.

Fuselier has authored or co-authored more than 610 papers and publications in scientific journals and conference proceedings. In 1995, Fuselier was elected a Fellow of the American Geophysical Union and in 2021 he was elected a member of the National Academy of Sciences for distinguished and continuing achievements in original research.

Fuselier joined SwRI as a program director in 2011. He was promoted to director in 2013 and executive director in 2015. In 2024, he was named the acting vice president of the Space Science Division.

Fuselier serves as an adjoint professor at the University of Texas at San Antonio as part of the SwRI-UT San Antonio Graduate Program in Physics. In 2025, he and his wife established the Stephen Fuselier and Elizabeth Packer Endowed Scholarship at UT San Antonio for students majoring in physics or electrical engineering.

What's the ROI on R&D in aging? New simulation tool, silverlingings.bio, explores geroscience's impact on US GDP growth and individual health

2026-02-04

New York, NY — The American Federation for Aging Research (AFAR) is pleased to announce the release of silverlinings.bio, an interactive report and simulation tool developed by AFAR Scholar-in-Residence Raiany Romanni-Klein, PhD, with support from AFAR, the Amaranth Foundation, and the Methuselah Foundation. Dr. Romanni-Klein spent the last two years working with a team of economists from Harvard, the Abundance Institute, and the University of Southern Carolina to develop an interactive simulation tool with returns on investments (ROI) for specific research & development (R&D) advancements in aging science ...

CFC replacements behind hundreds of thousands of tonnes of global ‘forever chemical’ pollution

2026-02-04

Chemicals brought in to help protect our ozone layer have had the unintended consequences of spreading vast quantities of a potentially toxic ‘forever chemical’ around the globe, a new study shows. Atmospheric scientists, led by researchers at Lancaster University, have for the first time calculated that CFC replacement chemicals and anaesthetics are behind around a third of a million tonnes (335,500 tonnes) of a persistent forever chemical called trifluoroacetic acid (TFA) being deposited from the atmosphere across the Earth’s surface between the years 2000 and 2022. And the rate ...

Pigs and grizzlies, not monkeys, hold clues to youthful human skin

2026-02-04

PULLMAN, Wash. — The secret to youthful appearance and repairing scars may lie in a microscopic skin structure humans share with pigs and grizzly bears — but, surprisingly, not monkeys. While it had been thought these ridge and valley-like skin microstructures — called rete ridges — form during fetal growth, researchers at Washington State University’s College of Veterinary Medicine found they actually develop shortly after birth and identified a key molecular signal that drives their development. The findings, published in the journal Nature, could lead to new therapies designed to reverse or slow skin aging and improve wound and scar ...

Innovative card deck by Case Western Reserve professor empowers kids to tackle stress head-on

2026-02-04

CLEVELAND—A Case Western Reserve University professor has developed an innovative card deck designed to help children manage stress and build emotional resilience in today’s challenging world. Following the COVID-19 pandemic—and amid ongoing global and societal stressors—Jennifer King, an associate professor and co-director of the Center on Trauma and Adversity at the Jack, Joseph and Morton Mandel School of Applied Social Sciences at Case Western Reserve, realized that people needed to know the fundamentals of stress management. She created “Take a Break” micropractice cards in 2022 to help people relax, ...

Blocking pain at the source: Hormone therapy rewires nerve signals in aging spines

2026-02-04

Low back pain (LBP) is one of the most common health problems worldwide, affecting people of all ages and placing a heavy burden on healthcare systems. Many patients experience persistent discomfort that interferes with work, sleep, and daily activities. Yet in most cases, doctors cannot identify a clear structural cause, making long-term treatment difficult. A new study published in Volume 14 of the journal Bone Research on January 22, 2026, suggests that a hormone treatment may help relieve chronic back pain by limiting abnormal nerve growth inside damaged spinal ...

Green chemistry: Friendly bacteria can unlock hidden metabolic pathways in plant cell cultures

2026-02-04

Plants are a rich and renewable source of compounds used in medicines, food ingredients, and cosmetics. Since growing an entire plant just to extract a few specific compounds is rather inefficient, scientists are turning to plant cell cultures as a more sustainable alternative. Cultured plant cells can act as ideal ‘biofactories’ that multiply quickly indoors and are unaffected by weather or seasons. Unfortunately, this strategy faces a long-standing problem: although plant cells contain thousands of genes capable of making diverse chemicals, only a small fraction of them are active under standard culture conditions. One possible ...

Uncommon names are increasing globally: Reflecting an increase in uniqueness-seeking and individualism

2026-02-04

Highlights Associate Professor Yuji Ogihara of Aoyama Gakuin University reviews empirical studies that examined temporal changes in the frequency of (un)common names. Accumulated evidence has demonstrated that uncommon names increased over time in many nations: Germany, the U.S., the U.K., France, Japan, China, and Indonesia. All the nations that were examined have shown an increase in uncommon names. Thus, the phenomenon is observed more generally, not locally in some limited nations. This increase in uncommon names reflects broader ...
