SAN ANTONIO — December 3, 2025 — Southwest Research Institute (SwRI) scientists believe they may have resolved a 39-year-old mystery about the radiation belts around Uranus. In 1986, when Voyager 2 made the first and only flyby of Uranus, it measured a surprisingly strong electron radiation belt at significantly higher levels than anticipated. Based on extrapolations from other planetary systems, Uranus’ electron radiation belt was off the charts. Since then, scientists have wondered ...

The dark web – a hidden corner of the internet accessed through privacy-preserving tools like the Tor browser – operates beyond the reach of traditional search engines and public platforms. Unlike the surface web, its architecture is deliberately designed to shield identities and activities from view, prioritizing anonymity over transparency. Although the dark web has existed for more than 20 years, research assessing mental health differences between its users and those who stay on the surface web remains limited. Its pseudo-anonymous ...

Managers’ narcissistic tendencies may fundamentally affect whether a company makes risky or safe moves as a response to the firm’s above-aspiration performance, according to a new study published in Strategic Management Journal. In a study that helps to clarify prior conflicting research, the researchers find evidence that high-narcissism CEOs respond to above-aspiration performance with more acquisitions, while low-narcissism CEOs avoid acquisitions. The study authors — Korcan Kavusan of Erasmus University, Daniel Z. Mack of Singapore Management University, Matthew P. Mount of ...

PULLMAN, Wash. — In times of economic upheaval, investors can get a clearer picture of the stock market’s future performance if they tune into how corporate insiders are trading stocks in their own companies. That’s a key finding from a new study of investor behavior during the Covid-19 pandemic from Washington State University researchers. The study, which was published in Pacific-Basin Finance Journal, examined the trading choices of insiders during the unprecedented market shocks of the Covid-19 pandemic — finding they often zigged when the market zagged. When most investors were selling stocks ...

To see if a fish is fresh, people recommend looking at its eyes and gills or giving it a sniff. But a more accurate check for food quality and safety is to look for compounds that form when decomposition starts. Now, researchers reporting in ACS Sensors have developed a simple, effective electronic device that quickly measures one of these compounds. The prototype sensor can determine how fresh a fish is in less than two minutes. For fish, signs of spoilage (cloudy eyes, bruised gills, foul or fishy odors) might take hours or even days to appear. In contrast, compounds such as hypoxanthine (HX) start forming ...

The microbes inside our bodies not only help break down food but also impact our health. Yet their precise influence is not always understood, especially in the presence of prescription drugs. Now, researchers in ACS Central Science report how one of the most abundant gut bacteria responds to tetracyclines, a class of commonly prescribed antibiotics. Newly characterized signals released by the bacterium could aid the host’s immune response, inhibit pathogens and restructure the gut microbiome. “We previously showed that exogenous molecules ...

All-solid-state batteries (ASSBs) using silicon (Si) anodes are among the most promising candidates for high-energy and long-lasting power sources, particularly for electric vehicles. Si can store more lithium than conventional graphite, but its volume expands by roughly 410% during charging. This swelling generates mechanical stress that cracks particles and weakens their contact with the solid electrolyte, disrupting the flow of ions and reducing efficiency. To address this, a research group led by Professor Yuki Orikasa from the College of Life Sciences, Ritsumeikan University, ...

A researcher from the University of Tokyo and a U.S.-based structural engineer developed a new computational form-finding method that could change how architects and engineers design lightweight and free-form structures covering large spaces. The technique specifically helps create gridshells, thin, curved surfaces whose members form a networked grid. The method makes use of NURBS surfaces, a widely used surface representation format in computer-aided design (CAD). It also drastically reduces computation cost — a task that previously took 90 hours on a high-end GPU completes in about 90 minutes on a standard CPU. Architects pay particular attention to surfaces capable of supporting ...

Macrolactones—large ring lactones—are core components of many natural products and pharmaceutical agents. Traditional synthetic routes rely on seco acids activated with condensing reagents, often requiring harsh conditions or multi-step procedures. An alternative approach using hydroxyaldehydes has remained limited, and radical-based macrolactonization of these substrates had never been reported.   Now, a research team led by Dr. Kenta Tanaka, Assistant Professor at the Research Institute for Interdisciplinary ...

Iron (Fe) is an essential micronutrient for the healthy growth of plants, including many staple crops like rice. Its deficiency remains a common agricultural problem that slashes crop yields, as it leads to impaired photosynthesis, respiration, and nitrogen metabolism. Thus, establishing mechanisms to ensure crops can efficiently take up and utilize Fe, especially in alkaline soils, is a high-stakes challenge for global food security.   Getting Fe into the roots is only the first step; the mineral must then be properly distributed throughout the plant, especially to its young leaves, developing grains, and other active growth tissues. This process ...

During a baby’s early months, the brain is developing rapidly. Billions of neural connections form, expand, and are pruned back, shaped by genetics, the environment, and timing. Though brain development continues throughout life, the early months are critical, particularly when it comes to interactions between a parent and child. What could scientists learn from high-quality brain function data during infancy? With a new $2.3 million, four-year grant from the National Institute of Biomedical Imaging and Bioengineering, part of the National ...

PULLMAN, Wash. — College students who binge drink may be acting on influences they brought from home, a new Washington State University-led study suggests. A recent survey shows that students who binge drink more than other students tend to have grown up in a home with more permissive attitudes toward drinking. Those students are also more likely to join Greek-affiliated organizations like fraternities or sororities. In a study published in the journal Behavioral Sciences, researchers surveyed parents and students about drinking attitudes ...
