A new study from the Hebrew University of Jerusalem challenges a long-held assumption in climate science by showing that aerosols—tiny particles suspended in the atmosphere—can either warm or cool the climate, depending on ...
When a person coughs or sneezes, they expel a cloud of microscopic particles capable of carrying viruses and bacteria that act as vectors for respiratory diseases such as flu, COVID-19 or tuberculosis. Understanding how these ...
From sizzling bacon in the kitchen to wildfire smoke in the sky, cooking and pollution release microscopic particles that affect humans' health, the air they breathe, and even weather and climate. New research from Virginia ...
The astronauts circling Earth on the Artemis mission sent back beautiful clear photos of the continents, clouds, and oceans. But we might be the exception. Many planets in the universe may be hazed in clouds of soot, according ...
Aerosols and clouds play a key role in Earth's climate budget. However, the extent to which they reflect solar energy depends heavily on how much water the particles can absorb. This so-called hygroscopicity has so far been ...
It may sound counterintuitive, but new research suggests that cleaning up air pollution could contribute to a weakening of the Atlantic Meridional Overturning Circulation (AMOC). This is the ocean current system that acts ...
How are cold air masses advancing in the United States connected to fertilizers carried by "flying rivers" from Africa that nourish the soils of the Brazilian Amazon? An article published in Geophysical Research Letters reveals ...
Fine particulate matter in the air or nanoparticles in water—a remarkable new technology developed at TU Wien makes it possible to detect tiny amounts of a wide range of substances in a very short time.
Geoengineering could protect the Amazon rainforest from climate change, new research shows. Stratospheric aerosol injection (SAI) aims to artificially cool Earth by increasing the reflection of incoming solar radiation, thereby ...
A new study shows that a specific type of silicone, the so-called methylsiloxanes, is widely present in the atmosphere across diverse environments. Also, concentrations appear to be much higher than expected. According to ...
