It's a rave: Underground acoustics amplify soil health      (via sciencedaily.com)     Original source 

Barely audible to human ears, healthy soils produce a cacophony of sounds in many forms -- a bit like an underground rave concert of bubble pops and clicks. Special recordings made by ecologists show this chaotic mixture of soundscapes can be a measure of the diversity of tiny living animals in the soil, which create sounds as they move and interact with their environment.

New research shows unprecedented atmospheric changes during May's geomagnetic superstorm      (via sciencedaily.com)     Original source 

On May 11, a gorgeous aurora surprised stargazers across the southern United States. That same weekend, a tractor guided by GPS missed its mark. What do the visibility of the northern lights have in common with compromised farming equipment in the Midwest? A uniquely powerful geomagnetic storm, according to new research.

Why do plants wiggle? New study provides answers      (via sciencedaily.com)     Original source 

Decades after his voyage on the HMS Beagle, Charles Darwin became fascinated by why plants move as they grow -- spinning and twisting into corkscrews. Now, more than 150 years later, a new study may have solved the riddle.

Researchers unveil mysteries of ancient Earth      (via sciencedaily.com)     Original source 

A team of researchers has made strides in understanding the formation of massif-type anorthosites, enigmatic rocks that only formed during the middle part of Earth's history. These plagioclase-rich igneous rock formations, which can cover areas as large as 42,000 square kilometers and host titanium ore deposits, have puzzled scientists for decades due to conflicting theories about their origins.

Ecologists put an insect group on century-old map of biodiversity      (via sciencedaily.com)     Original source 

The distribution of species around the globe is not a random process but an outcome resulting from several evolutionary mechanisms as well as past and current environmental limitations. As a result, since the mid-19th century, biologists have identified several main regions, called biogeographic realms, that depict these large ensembles of species around the world. These biogeographic realms represent one of the most fundamental descriptions of biodiversity on Earth and are commonly used in various fields of biology.

Climate change raised the odds of unprecedented wildfires in 2023-24      (via sciencedaily.com)     Original source 

Unprecedented wildfires in Canada and parts of Amazonia last year were at least three times more likely due to climate change and contributed to high levels of CO2 emissions from burning globally, according to the a new systematic review. The State of Wildfires report takes stock of extreme wildfires of the 2023-2024 fire season (March 2023-February 2024), explains their causes, and assesses whether events could have been predicted. It also evaluates how the risk of similar events will change in future under different climate change scenarios.

Record-breaking recovery of rocks that originated in Earth's mantle could reveal secrets of planet's history      (via sciencedaily.com)     Original source 

Scientists have recovered the first long section of rocks that originated in the Earth's mantle, the layer below the crust and the planet's largest component. The rocks will help unravel the mantle's role in the origins of life on Earth, the volcanic activity generated when it melts, and how it drives the global cycles of important elements such as carbon and hydrogen.
