A wildlife bridge cuts crashes 91%, and frogs wear bacterial armor

Cameras now show elk crossing in herds, and pronghorn on the west side of the highway for the first time in decades 251. Bears, deer and coyotes have used it too, and so has the federally threatened Preble's meadow jumping mouse, helped by piles of wood that biologists laid down as covered routes 251. Biologist Brandon Marette described the old highway as "an effective wall that they had to play Frogger and try to get across." 251

In the lab, half of each species was exposed to the fungus, and within each group half got an antibiotic bath first to wipe out their skin bacteria 263. Clay robber frogs survived well until the antibiotics stripped their skin microbes, and then their survival plummeted 263. Hensel's frogs did badly either way 263. Schuck also grew about 700 bacterial strains from the skin and scored how each one affected the fungus 263.

In this form of the disease the heart still pumps, but it has become too stiff to relax and fill between beats 7. The compound helped the stiff tissue relax, reduced scarring and limited abnormal enlargement, and it also improved relaxation in engineered human heart tissue 7. The team reports for the first time that urolithin A activates a protein called PKGlα, acting on one specific amino acid inside it 7.

In 2025 there were no wildfires in the territory at all 237. The project is called Paamari, the Asháninka word for fire, and it pairs CARE with the charity Cool Earth 237. Hundreds of community members have trained as brigadistas, using satellite imagery, drones and radio systems to spot smoke and check whether it is a wildfire or a controlled burn 237. Brigadista Romer Quentimari Garcia keeps watch near the meeting of the Ene and Tambo rivers 237.

By 2026 the losses had shrunk to 5 to 6 percent, on par with France and Belgium and better than Greece and Serbia 192. The city's grid reliability index rose from around 70 percent in 2002 to above 99.9 percent 192.

Pairing it with trospium, which does not cross into the brain, cut adverse events roughly in half while keeping the effect at the M1 and M4 muscarinic receptors 93. Unlike drugs that block dopamine D2 receptors, xanomeline was not associated with extrapyramidal symptoms, weight gain, metabolic syndrome or prolactin elevation 90. An estimated 30% of people with schizophrenia do not have medications that adequately address their symptoms 93.

Around 1,300 BCE, the armies of Ramses II and the Hittite king Muwatallis II fought what may have been the largest chariot battle in history, with tens of thousands of soldiers, and it ended in a stalemate 234. Muwatallis's successor later made peace with Ramses 234. It survives in three Akkadian cuneiform copies and one Egyptian hieroglyphic version at Karnak, making it the only ancient Near Eastern treaty with both sides' versions preserved 234. Article 14 pledges "peace and fraternity without leaving place among them to any enmity" 234.
