☆ Mars could be driving ‘giant whirlpools’ in the Earth’s deep oceans, new study finds
  + stars: | 2024-03-12 | by ( Laura Paddison | ) edition.cnn.com   time to read: +5 min
CNN —Mars may be around 140 million miles away from Earth, but the red planet is influencing our deep oceans by helping drive “giant whirlpools,” according to new research. The sediments revealed that deep-sea currents weakened and strengthened over 2.4 million-year climate cycles, according to the study published Tuesday in the journal Nature Communications. For the Earth, this interaction with Mars translates to periods of increased solar energy — meaning a warmer climate — and these warmer cycles correlate with more vigorous ocean currents, the report found. The authors describe these currents, or eddies, as “giant whirlpools” that can reach the bottom of the deep ocean, eroding the seafloor and causing large accumulations of sediments, like snowdrifts. Deep-sea sediments build in continuous layers during calm conditions but strong ocean currents disrupt this, leaving a visible stamp of their existence.

☆ Sanfordiacaulis: New ancient tree species looks like it could be from the mind of Dr. Seuss
  + stars: | 2024-02-02 | by ( Ayurella Horn-Muller | ) edition.cnn.com   time to read: +7 min
The authors said these new and unusual fossil trees not only bear a surprising shape reminiscent of a Dr. Seuss illustration, they reveal clues about a period of life on Earth of which we know little. Few tree fossils that date back to Earth’s earliest forests have ever been found, according to Gastaldo. Most ancient tree specimens are relatively small, he noted, and often discovered in the form of a fossilized trunk with a stump or root system attached. Wilf noted via email that the “unusual” new fossil tree was a relic of a time period from which there are almost no tree fossils. The peculiar set of tree fossils presents proof of a “failed experiment of science and evolution,” Stimson added.
