Unraveling the mysteries of fog in complex terrain      (via sciencedaily.com)     Original source 

While fog presents a major hazard to transportation safety, meteorologists have yet to figure out how to forecast it with the precision they have achieved for precipitation, wind and other stormy events. This is because the physical processes resulting in fog formation are extremely complex, Now researchers report their findings from an intensive study centered on a northern Utah basin and conceived to investigate the life cycle of cold fog in mountain valleys.

New material allows for better hydrogen-based batteries and fuel cells      (via sciencedaily.com)     Original source 

Researchers have developed a solid electrolyte for transporting hydride ions at room temperature. This breakthrough means that the full advantages of hydrogen-based solid-state batteries and fuel cells can be had without the need for constant hydration. This will reduce their complexity and cost, which is essential for advancing towards a practical hydrogen-based energy economy.

Reduced air pollution during pandemic points to way to preserve Himalayan glaciers      (via sciencedaily.com)     Original source 

Reducing air pollution to levels similar to those during the coronavirus pandemic could protect the glaciers in the Himalayas and prevent them from disappearing by the end of the century. This is the conclusion reached by an international research team analyzing the situation during the COVID-19 lockdown in 2020.

World's smallest 'fanged' frogs found in Indonesia      (via sciencedaily.com)     Original source 

Researchers have identified a species of frog new to science. The Indonesian amphibian is the size of a quarter, unlike its two-pound cousins, and has tiny fangs. Nearly uniquely among amphibians, they lay their eggs on the leaves of trees, and the males guard and tend to the nests.

Scientists provide recipe to halve pollution from food production      (via sciencedaily.com)     Original source 

A major report has put forward solutions to halve nitrogen pollution from agriculture and the food system in Europe, including reducing meat and dairy consumption, fertilizer use and food waste. Inefficiencies in farms, retail and wastewater practices mean that the nitrogen use efficiency of the food system in Europe is only 18%, leaving most of the remainder leaking into air, water and soils. The new report, Appetite for Change, has been produced by a group of researchers coordinated by the UK Centre for Ecology & Hydrology (UKCEH), the European Commission, Copenhagen Business School and the National Institute for Public Health and the Environment (RIVM) of The Netherlands.

Low economic growth can help keep climate change within the 1.5 °C threshold      (via sciencedaily.com)     Original source 

A new study shows that economic growth rates make a big difference when it comes to prospects for limiting global warming to 1.5 °C, as per the Paris Agreement. A recent study shows that pursuing higher economic growth may jeopardize the Paris goals and leave no viable pathways for humanity to stabilize the climate. On the contrary, slower growth rates make it more feasible to achieve the Paris goals.

Snowflakes swirling in turbulent air as they fall through a laser light sheet      (via sciencedaily.com)     Original source 

A winter wonderland calls to mind piles of fluffy, glistening snow. But to reach the ground, snowflakes are swept into the turbulent atmosphere, swirling through the air instead of plummeting directly to the ground. Researchers found that regardless of turbulence or snowflake type, acceleration follows a universal statistical pattern that can be described as an exponential distribution.
