Some Alaskan trout use flexible guts for the ultimate binge diet

Dolly Varden trout in Alaska's Chignik Lake watershed use their intestines to gorge on salmon eggs, doubling in size, then shrink back down after the food pulse ends. This adaptation helps them survive months of scarcity and thrive despite nutrient-poor environments.

Natural climate swings contribute more to increased monsoon rainfall than global warming

The Northern Hemisphere monsoon has intensified, with a 9.5% increase in rainfall, due to natural climate swings rather than global warming alone. Natural long-term climate swings, such as the Interdecadal Pacific Oscillation and Atlantic Multidecadal Oscillation, contribute significantly more to this intensification.
