popsci.com – The arboreal shift from green to gold marks the beginning of autumn for many in temperate climes, a color change that goes hand in hand with pumpkin spice lattes and cozying up as the weather cools. But, like countless natural processes, this much-loved seasonal indicator is subject to disruption as the Earth’s temperature steadily warms.

Nature constantly evolves new ways to kill, which means pathogens will develop new methods of resistance to current treatments, but pharmaceutical companies also have little incentive to develop new antibiotics. Instead, they have obstructions when the U.S.

eurekalert.org – Researchers analyzing snow and stream samples from the National Geographic and Rolex Perpetual Planet Everest Expedition have found evidence of microplastic pollution on Mount Everest. While the highest concentrations of microplastics were around Base Camp where hikers and trekkers spend the most time, the team also found microplastics as high up as 8,440 meters above sea level, just below the summit. The findings appear November 20 in the journal One Earth.
