Artificial light is luring birds to cities and sometimes to their deaths      (via sciencedaily.com)     Original source 

Scientists used weather radar data to map bird stopover density in the United States and found that artificial light is a top indicator of where birds will land. City lights lure birds into what can be an ecological trap -- with buildings that lead to collisions, less habitat, scarcer food, and more people and cats. The study provides the first continent-wide maps of migration stopover hotspots in the contiguous United States, and knowing these broadscale layover patterns can help in the development of conservation plans.

Researchers decode aqueous amino acid's potential for direct air capture of CO2      (via sciencedaily.com)     Original source 

Scientists have made a significant stride toward understanding a viable process for direct air capture, or DAC, of carbon dioxide from the atmosphere. This DAC process is in early development with the aim of achieving negative emissions, where the amount of carbon dioxide removed from the envelope of gases surrounding Earth exceeds the amount emitted.

One of the largest magnetic storms in history quantified: Aurorae covered much of the night sky from the Tropics to the Polar Regions      (via sciencedaily.com)     Original source 

An international multidisciplinary team consisting of solar physicists, geophysicists, and historians from nine countries analysed observations of an extreme solar-terrestrial storm reported in historical records from February 1872. Their findings confirm that a moderate sunspot group triggered one of the largest magnetic storms ever recorded, almost covering the entire night sky with colourful aurorae in both hemispheres. If such an extreme storm occurred today, it would severely disrupt modern technological infrastructure. Their study emphasizes the importance of looking at historical records in light of modern scientific knowledge.

The record storm surge in October 2023 caused severe damage to the German Baltic coast. Effective adaptation scenarios to rising sea levels are therefore becoming increasingly urgent. In two recent studies, researchers have modeled both the flooding extent along the Baltic Sea coastal areas and two possible upgrades for current dike lines in high resolution. They modeled various storm surge and sea level rise scenarios.
