Decades ago, humans began employing chemicals to enhance clouds' ability to produce rain and snow, a practice that is increasingly relevant as climate change exacerbates heat and dryness in certain areas. While embraced in countries like the US and the United Arab Emirates, cloud seeding remains contentious due to potential unintended outcomes such as excessive precipitation or heightened pollution levels.

Bumblebees can surprisingly withstand days underwater, according to a study published Wednesday, suggesting they could withstand increased floods brought on by climate change that threaten their winter hibernation burrows. Researchers placed 143 hibernating queen bumblebees in tubes -- some with no water as a comparative group, some floating in water and some fully submerged using a plunger for a period ranging from eight hours to seven days, according to the study published in the journal Biology Letters.

Research unlocked the genome of Coffea arabica, revealing its ancient Ethiopian forest origins. Led by experts like Victor Albert and Patrick Descombes, the study emphasized the importance of disease-resistant breeding for Arabica coffee varieties.
