(Barcelona, Spain, Wednesday 8 September 2025) The growing use of GLP-1 receptor agonists may affect the interpretation of oncological FDG PET-CT scans, new research presented today at the 38th Annual Congress of the European Association of Nuclear Medicine (EANM'25) has revealed.1 GLP-1 receptor agonists are now widely prescribed for individuals with type 2 diabetes and weight loss, with a 700% increase in usage reported in the United States between 2019 and 2023.² These medications alter glucose metabolism, gastric motility and sympathetic tone, which may lead to unique uptake patterns on PET-CT. Previous case reports have shown increased FDG uptake in skeletal ...

LA JOLLA, CA— Cellular membrane proteins play many important roles throughout the body, including transporting substances in and out of the cell, transmitting signals, speeding up reactions and helping neighboring cells stick together. When they malfunction, it can cause serious diseases including cancer, making them attractive drug targets. But understanding how membrane proteins behave and function can be challenging because their position within the cell’s lipid membrane—a tightly-packed double layer of fat-like molecules—makes them difficult to study. Now, Scripps Research ...

WASHINGTON — In 2023, Panama experienced one of the worst droughts in its recorded history, and it severely depleted water available to the Panama Canal, so much that it decreased shipping by 30%. A new study projected that those historic water lows could become the new norm if greenhouse gas emissions continue to rise. “If we mitigate emissions and we choose one of the lower emissions pathways, then it really keeps this system pretty stable,” said Samuel Muñoz, lead author of the a new study and a researcher studying  hydrologic and climatic variability at Northeastern University. “But if we don't, then these low water levels that ...

Public water systems in the U.S. were far less likely to report suspiciously rounded lead levels after the Flint, Michigan water crisis drew national outrage and federal scrutiny, according to new research led by the University of Massachusetts Amherst.  The study, published as the first article in the latest issue of American Economic Review: Insights, introduces new statistical methods to distinguish between natural rounding and potential “threshold manipulation” in reported figures. “Existing ...

National security officials are "overwhelmingly overconfident," which hinders their ability to accurately assess uncertainty, according to new research by a Dartmouth government professor. When they thought statements had a 90% chance of being true, the statements were only true about 60% of the time, according to the study.  The findings are published in the Texas National Security Review. About 1,900 national security officials from more than 40 NATO allies and partners were surveyed on the uncertainty of current and future states of the world, and delivered a total of 60,000 assessments. ...

Researchers have unveiled a surprising new way that soil microbes can use sunlight energy — even after the lights go out. A team from Kunming University of Science and Technology and the University of Massachusetts Amherst has developed a “bio-photovoltage soil-microbe battery” that can capture, store, and release solar energy to power the breakdown of antibiotic pollutants in the dark. The study, published in Environmental and Biogeochemical Processes, shows that common soil bacteria known as Bacillus megaterium can partner with iron minerals to form a living biofilm that behaves like a rechargeable geochemical capacitor. When exposed to light, the iron-bacteria film ...

A new study published in Science Advances about centuries-old horse and donkey bones, unearthed in Jamestown, Virginia, is rewriting the story of how these animals first arrived in North America. While written records from the earliest English explorers show that horses were among the animals brought to Virginia, the new zooarchaeological analysis of animal remains found at Jamestown is the first to show that colonists also brought donkeys to the New World. The study also reveals a dark ending to these equids in the colony: The horses and donkeys were likely butchered and eaten during Jamestown’s infamous winter of starvation. “There ...

MIAMI (Oct. 7, 2025) – As drones become increasingly common in U.S. skies – delivering packages, inspecting bridges, even monitoring crops – the danger of cyberattacks has grown too. A drone hijacked by hackers could suddenly veer off course, speed up, stall in midair, or crash. Once compromised, the machine is useless, often left as little more than expensive junk. Florida International University researchers have found a way to fight back. At the IEEE International Conference on Dependable Systems and Networks, FIU computer scientists unveiled SHIELD, a defensive system that can detect and neutralize ...

There are relatively few snow leopards in the world, and it has likely been that way for a long time, a new study indicates. This situation increases their risk of extinction in a changing environment. The Stanford-led research, published in Proceedings of the National Academy of Sciences, found very low genetic diversity among the elusive big cats, who have an estimated population of less than 8,000. They are also highly specialized to their habitat in the arid, mountainous regions of 12 Asian countries, including Russia, Afghanistan, Nepal, and Tibet. “Snow ...

Rotavirus causes severe dehydrating diarrhea in infants and young children, contributing to more than 128,500 deaths per year globally despite widespread vaccination efforts. Although rotavirus is more prevalent in developing countries, declining vaccination uptake in the United States has resulted in increasing cases in recent years. New research from Washington University School of Medicine in St. Louis has identified a key step that enables rotavirus to infect cells. The researchers found that disabling the process in tissue culture ...

We have all been in that situation: the moving boxes are large and heavy, but we are determined to carry them all in one trip, even if that means we can’t see where we’re going. In the tropics, some leaf-cutter ants face a similar challenge: carrying a load that is several times their body weight. To make matters even more difficult, scientists at the Smithsonian Tropical Research Institute (STRI) in Panama recently discovered that carrying oversized weights may create “blind spots” when leafcutter ants transport ...
