Shedding light on the chemical enigma of sulfur trioxide in the atmosphere      (via sciencedaily.com)     Original source 

Researchers discovered that sulfur trioxide can form products other than sulfuric acid in the atmosphere by interacting with organic and inorganic acids. These previously uncharacterized acid sulfuric anhydride products are almost certainly key contributors to atmospheric new particle formation and a way to efficiently incorporate carboxylic acids into atmospheric nanoparticles. Better prediction of aerosol formation can help curb air pollution and reduce uncertainties concerning climate change.

Constantly on the hunt for food: Harbor porpoises more vulnerable than previously thought      (via sciencedaily.com)     Original source 

Constantly on the hunt for food: Harbor porpoises more vulnerable than previously thought to the disturbances from humans. The small whales spend more than 60 percent of their day hunting small fish to stay warm in the cold waters. New research shows that harbor porpoises spend little energy on this hunting strategy, but that it makes them vulnerable to human disturbance.

Effectiveness of GBGI infrastructure in mitigating urban heat, proposing nine-stage framework for development of a sustainable city      (via sciencedaily.com)     Original source 

Primarily due to the impact of urbanisation and global warming, urban heatwaves have become a challenging issue worldwide, with Hong Kong persistently experiencing record-breaking high-temperature days. Mitigating urban heat through green and blue infrastructures is essential for creating a sustainable environment. Researchers have conducted a study on the effectiveness of green interventions in cooling urban heat across various regions that can assist policymakers in prioritizing effective interventions to develop sustainable cities.

Sexual parasitism helped anglerfish invade the deep sea during a time of global warming      (via sciencedaily.com)     Original source 

Members of the vertebrate group including anglerfishes are unique in possessing a characteristic known as sexual parasitism, in which males temporarily attach or permanently fuse with females to mate. Now, researchers show that sexual parasitism arose during a time of major global warming and rapid transition for anglerfishes from the ocean floor to the deep, open sea.
