A recent study has shed new light on the planet’s inner core, revealing that it may be changing shape and reversing its spin. Researchers inferred signs of deformation from powerful earthquakes that reach the heart of the Earth. This change could impact the planet’s magnetic field, which shields us from solar radiation and helps guide animal migrations.
Meanwhile, loggerhead sea turtles have been found to memorize magnetic fields, allowing them to navigate without landmarks. The turtles rely on the Earth’s magnetic field to track location and orientation, but a new study shows they also retain memories of where they’ve eaten in the past.
In space news, astronauts Butch Wilmore and Suni Williams may be returning to Earth sooner than planned due to NASA’s agency changes. Additionally, researchers have detected a high-energy cosmic particle in the Mediterranean Sea, which could provide clues about extreme astronomical events.
Other discoveries include an analysis of ancient human bones suggesting cannibalism was practiced as a funeral ritual, a fungus that turns cave spiders into “zombies,” and the discovery of a monster radio jet formed during the early days of the universe.
These findings highlight the wonders and mysteries of our world, from the Earth’s core to the depths of space.
