Eye Of Sahara Explained: NASA says Richat Structure not a crater; dunes, dust reshape global systems
Astronauts marvelled at the Sahara's 'Eye of the Sahara,' the Richat Structure, a geological wonder in Mauritania. Far from a meteor impact, this massive formation, spanning 25-30 miles, is a domed anticline sculpted by millions of years of differential erosion. Its distinct rings, revealing ancient rock layers, serve as a vital landmark for space missions.
Panama Upwelling Failure: Scientists flag first breakdown; ecosystems and fisheries at risk
For the first time in 40 years, a vital Pacific Ocean upwelling off Panama failed in 2025. This biological engine, crucial for fish populations and coastal communities, didn't activate as trade winds weakened. Scientists, monitoring this rare event, suspect climate disruption, raising alarms about interconnected ocean systems and the need for better tropical ocean observation.
Rocks have been sending an SOS before they collapse, and scientists finally understand it
Scientists have discovered that rocks send out chemical signals before they break. Researchers have created a model to understand these signals, offering a potential early warning system for geological events. This breakthrough could help predict landslides and earthquakes. The technology is still developing but promises to provide crucial alerts for communities in geologically active areas.
