Sep. 29, 2025 Researchers have revealed how polymyxins, crucial last-resort antibiotics, break down bacterial armor by forcing cells to overproduce and shed it. Astonishingly, the drugs only kill bacteria when they’re active, leaving dormant cells untouched. This discovery could explain recurring infections and inspire strategies to wake bacteria up before ...

Sep. 24, 2025 Rice, a staple for billions, is one of the most resource-hungry crops on the planet—but scientists may have found a way to change that. By applying nanoscale selenium directly to rice plants, researchers dramatically improved nitrogen efficiency, boosted yields, and made grains more nutritious while reducing fertilizer use and cutting greenhouse gas ...

Sep. 23, 2025 Researchers have shown that stress and retrovirus levels are tightly linked to disease in koalas. High KoRV loads make koalas more vulnerable to chlamydia, worsening epidemics in stressed populations. Protecting habitats, careful breeding, and antiviral trials are now being pursued to give koalas a fighting chance at ...

Sep. 23, 2025 A long-term study in Colorado reveals that insect populations are plummeting even in remote, undisturbed areas. Over two decades, flying insect abundance dropped by more than 70%, closely linked to rising summer temperatures. The results suggest that climate change, not just human land use, is driving massive losses. Scientists warn that biodiversity hotspots, especially mountain ecosystems, are ...

Sep. 22, 2025 Researchers found that ice can trigger stronger chemical reactions than liquid water, dissolving iron minerals in extreme cold. Freeze-thaw cycles amplify the effect, releasing iron into rivers and soils. With climate change accelerating these cycles, Arctic waterways may face major ...

Sep. 18, 2025 The Dead Sea isn’t just the saltiest body of water on Earth—it’s a living laboratory for the formation of giant underground salt deposits. Researchers are unraveling how evaporation, temperature shifts, and unusual mixing patterns lead to phenomena like “salt snow,” which falls in summer as well as winter. These processes mirror what happened millions of years ago in the Mediterranean, ...

Sep. 12, 2025 Forever chemicals known as PFAS have turned up in an unexpected place: beer. Researchers tested 23 different beers from across the U.S. and found that 95% contained PFAS, with the highest concentrations showing up in regions with known water contamination. The findings reveal how pollution in municipal water supplies can infiltrate popular products, raising concerns for both consumers and ...

Sep. 19, 2025 From the wreck of the royal Danish-Norwegian flagship Gribshunden, archaeologists have uncovered a rare glimpse into the naval power of the late Middle Ages. This warship, lost in 1495, carried an arsenal of small guns designed for close-range combat, symbolizing the technological leap that allowed European nations to dominate the seas. More than just a vessel, it served as King Hans’ floating ...

Aug. 30, 2025 Scientists have finally uncovered direct genetic evidence of Yersinia pestis — the bacterium behind the Plague of Justinian — in a mass grave in Jerash, Jordan. This long-sought discovery resolves a centuries-old debate, confirming that the plague that devastated the Byzantine Empire truly was caused by the same pathogen behind later outbreaks like the Black ...

Aug. 16, 2025 Chemical evidence from a stalagmite in Mexico has revealed that the Classic Maya civilization’s decline coincided with repeated severe wet-season droughts, including one that lasted 13 years. These prolonged droughts corresponded with halted monument construction and political disruption at key Maya sites, suggesting that climate stress played a ...
