Gainesville, Fla — Global unprovoked shark bites returned to near-average levels in 2025, following a sharp reduction the year prior. There was a total of 65 unprovoked shark bites worldwide in 2025, slightly less than the most recent 10-year average of 72. Nine of last year’s bites resulted in fatalities, compared to the ten-year average of six. “The International Shark Attack Files provide baseline data about shark attacks on people that are rigorously and scientifically investigated, evaluated and summarized on an annual basis. While a significant fraction of incidents likely go unreported, the temporal trends, and local and global patterns of incidents ...

Highlights: Heart health and heart disease risk go beyond the heart. Diabetes and kidney disease are major risk factors for heart disease, yet many cases are undiagnosed. Regular screening of connected health factors such as blood pressure, cholesterol, blood glucose (sugar), waist circumference and kidney function, and appropriate treatment when needed can help prevent heart disease. DALLAS, Feb. 18, 2026 — Diabetes and kidney disease are major risk factors for heart disease, yet many cases are undiagnosed. In addition, a consumer survey done ...

For five Januarys starting in 2016, researchers and students from the Norwegian University of Science and Technology (NTNU) travelled to a small valley outside of Svalbard’s main city with big jugs of liquid water and an unusual goal: To encase selected plant plots in a thick cover of ice. Their focus was a plant community dominated by the polar willow, a critical year-round food for Svalbard’s reindeer population. They wanted to see what happens to these plant communities during winter weather extremes, where prolonged rain instead of snow can freeze the ground solid and encase ...

Los Angeles, CA – February 18, 2026 - Dr. Vadim Jucaud’s lab at the Terasaki Institute has developed a vascularized liver tissueoid-on-a-chip (LToC) platform that recapitulates key structural, functional, and immunological features of human liver tissue, enabling the study of liver regeneration and immune-mediated allograft rejection in a physiologically relevant human system. Liver transplantation remains the primary therapeutic option for patients with end-stage liver disease, yet progress in understanding transplant rejection and tissue regeneration has been limited by the lack of experimental models that accurately reflect human liver architecture and immune interactions. ...

EVERETT, Wash. – Restaurants looking for new ways to engage and inform customers may benefit from incorporating augmented reality (AR) technology into their menus, according to new research from Washington State University. The study, published in the International Journal of Hospitality Management, finds that AR menus can significantly increase customers’ interest in visiting a restaurant and may result in more positive word-of-mouth marketing, when compared to printed or QR-code menus. Led by Soobin Seo, professor of hospitality business ...

Why do some systems collapse suddenly after what seems like a minor disturbance? A single transmission line failure can cascade into widespread blackouts. A delayed shipment can ripple through a global supply chain, emptying store shelves far from the original disruption. A rumor spreading in a small online network can spark nationwide panic. In nature, a slight environmental shift can throw an ecosystem into chaos, and a local disease outbreak can quickly escalate into an epidemic. New research suggests that in many of these cases, ...

Background and objectives Thalassemia is a group of anemias that result from inherited defects in the production of the beta chain of hemoglobin. It is stabilized by gamma globin, which combines to form fetal hemoglobin. One therapeutic approach is to target histone deacetylase (HDAC), which plays an important role in controlling beta thalassemia. This study sought to identify a natural inducer for treating this disease. Methods Twenty-five Andrographis paniculata compounds were screened using Schrödinger Suite 2020 (Maestro 12.3) for ligand preparation, grid generation, glide extra precision docking and molecular mechanics/generalized ...

Radioactive cesium ions, due to their high-water solubility, pose a serious threat to human health and the environment. Conventional adsorbents such as Prussian blue (PB), although effective for cesium removal, often involve complex fabrication and high operational costs. Researchers have now developed an innovative electrochemical electrode by depositing PB onto chemically treated carbon cloth, achieving high cesium adsorption capacity and excellent reusability, with strong potential for practical wastewater treatment applications. Although regarded as a clean and sustainable energy source, nuclear fission requires ...

Living cells are highly organized, yet they are not assembled using rigid blueprints or by following a predetermined plan. Instead, order emerges on its own from countless interactions between molecules that are constantly moving and rearranging. One of the most striking examples of this emerging order is the left–right asymmetry. This type of chirality—the property of an object that makes it different from its mirror image—is essential for many biological processes and can be observed throughout nature. Interestingly, how both small- and large-scale order arise from interactions ...

While there are plenty of historical topics U.S. citizens agree on—generally events and figures from the Civil War up to the end of the Cold War—the birth of the nation isn’t one of them, according to a new report from Johns Hopkins SNF Agora Institute and a nonprofit called Millions of Conversations.  The country’s founding has become one of the most polarizing eras in history, the new research finds, just as the United States is starting to celebrate its 250th anniversary this year. Older generations in the survey believe American ...

CLEVELAND—Researchers at Case Western Reserve University have discovered a way to breach one of cancer’s most stubborn defenses: the impenetrable fortress that solid tumors build around themselves. By injecting nanobubbles filled with inert gas into tumors and “jiggling” them with ultrasound, the team successfully broke down tumor barriers enough for treatment-bearing molecules to get inside, according to results of a new study published in ACS Nano. “The physical barrier is limiting delivery of cancer drugs, especially for new immunotherapies,” ...

Plastics have become an integral part of modern society thanks to their durability and resistance to water. However, precisely these properties turn them into persistent disruptors of ecological cycles. As a result, unrecovered plastic is accumulating across ecosystems and becoming an increasingly ubiquitous component of global food chains, raising growing concerns about potential impacts on human health. In an effort to address this challenge, the use of biomaterials as substitutes for conventional plastics has long been explored. However, their widespread adoption has been limited by a fundamental drawback: most biological materials weaken when ...

Studying foraging behavior in marine mammals is especially difficult. Unlike terrestrial animals, which can often be directly observed, marine mammals feed underwater and across vast, remote areas, making it challenging to determine where and what they eat. Most diet studies rely on stomach contents of stranded animals, making it impossible to know where or when feeding occurred. In the Arctic, however, where Inuit communities hunt marine mammals as part of a subsistence lifestyle, this limitation can be overcome. By comparing ...

The days of dropping a thermal imaging camera and replacing an expensive lens are coming to an end with a new repairable lens developed by Flinders University scientists.  A high-performance lens for infrared cameras invented by Flinders researchers is emerging as a lower cost, more sustainable option for industries whish use thermal imaging cameras, including security and surveillance, medicine, electrical engineering, electronics, defence and autonomous vehicle operation.  The new infrared thermal imaging lens, ...

Antimicrobial resistance (AMR) in common foodborne bacteria such as Salmonella and Campylobacter continues to be a public health concern across Europe, according to a new joint report from the European Food Safety Authority (EFSA) and the European Centre for Disease Prevention and Control (ECDC). While resistance to commonly used antimicrobials remains widespread in foodborne bacteria such as Salmonella and Campylobacter, several countries have reported progress in reducing resistance levels in humans and in food-producing animals. Because these foodborne bacteria can spread from animals and food to humans, causing severe infections ...

CLEVELAND—Among the enduring challenges of storing energy—for wind or solar farms, or backup storage for the energy grid or data centers—is batteries that can hold large amounts of electricity for a long time. In addition to having a large capacity—potentially enough to power a neighborhood or small city for days or weeks—ideally these batteries would be safe, affordable and environmentally harmless. With an eye toward meeting those benchmarks, researchers at Case Western Reserve University are developing novel electrolytes—fluids that can conduct ions—for ...

Mobile robots must continuously estimate their position to navigate autonomously. However, satellite-based navigation systems are not always reliable: signals may degrade near buildings or become unavailable indoors. To operate safely and efficiently, robots must interpret their surroundings using onboard sensors and robust localization algorithms. Researchers at Miguel Hernández University of Elche (UMH) in Spain have developed a hierarchical localization system that significantly improves robot positioning in large, changing environments. The method addresses one of the most challenging ...

Interbrain synchrony is the simultaneous activity of neural networks across the brains of people who are socially interacting –- for example talking, learning, singing, or working together. Having brains that are thus synchronized or ‘in tune’ can help people boost their emotional connection, improve communication, and align their attention. Neural synchrony is thought to be important for healthy bonding between parents and children. And now, a team of scientists in the UK has found that neural synchrony ...

Hip fractures are common in the elderly, with many patients experiencing a decline in Activities of Daily Living (ADL) post-surgery. Therefore, postoperative rehabilitation plays a crucial role in helping patients recover to their pre-injury ADL level. Previous studies have shown that providing rehabilitation on weekdays and outside of normal business hours, such as on the weekend and public holidays, during hospitalization promotes improvements in ADL. However, many medical institutions ...

Researchers at Kumamoto University have discovered that behavioral changes during the COVID-19 pandemic—particularly widespread mask-wearing—may have reduced the risk of certain types of heart attacks triggered by air pollution. The study, led by Dr. Masanobu Ishii and colleagues, was published in the European Society of Cardiology’s flagship journal, European Heart Journal. Air pollution and heart attacks Fine particulate matter known as PM2.5—tiny airborne particles small enough to penetrate ...

Professor Pei-Qiang Huang's research group at Xiamen University recently reported the first reduction-cross-coupling reaction of aliphatic tertiary amides with 4-cyanopyridine via iridium and photoredox tandem catalysis. This method is based on the formation of imineonium through iridium-catalyzed hydrosilylation and acid catalysis, followed by tandem photocatalysis to generate two radicals (C,N,N trialkyl α-amino radical and stable 4-cyano-1,4-dihydropyridine radical) which then undergo ...

A new Edith Cowan University (ECU) study has found advertisements that encourage healthy choices can reduce cravings and intentions to consume unhealthy foods, and in some cases a 15-second message may be more effective than traditional 30-second commercials.  Led by Dr Ross Hollett, the research investigated how the length and framing of junk food and anti-junk food ads influence immediate cravings among adults in different Body Mass Index (BMI) categories.  Anti-junk food ads are public health campaigns designed to discourage people from eating unhealthy foods, either by warning about ...
