Unusual Blobs Detected Deep Within Earth in Surprising Locations

Waves rippling from Earth’s core provide valuable clues about its composition and the distribution of its materials. Researchers from ETH Zurich and Caltech have used seismic waves to uncover unexpected chunks of Earth’s plates in surprising locations. For over a century, geologists have mapped Earth’s interior by analyzing how seismic signals travel at different speeds […]

Ancient Antarctic Ice Uncovers Spike in Wildfires During Past Climate Changes

Climatology, Earth Science, Environmental Science / Jorge Paka

Microscopic bubbles preserved in ancient Antarctic ice have uncovered periods of increased global wildfires that align with abrupt climate changes. Although climate shifts are typically marked by temperature fluctuations, alterations in tropical rainfall, and methane spikes, the role of wildfires had remained unrecognized until now. “We weren’t specifically searching for evidence of wildfires,” explained lead

Air Pollution from the Roman Empire May Have Reduced Europe’s IQ

Healthcare, Medicine / Eduardo Paulo

At its height, the Roman Empire’s influence spanned across land, sea, and even the skies. During the peak of Roman imperialism, air pollution became so widespread that researchers now believe it may have caused significant neurological damage across much of Europe, including what is now Great Britain. Ice-core data from the Arctic reveals that atmospheric
