carbon, which appears to have reacted with the sediment at low temperatures long after the material was deposited on the lake bottom. An annotated version of the image of “Cheyava Falls” indicates the markings akin to leopard spots, which have...

Arabia, wind-swept sands have revealed a remarkable window into the prehistoric past. Along the perimeter of a long-vanished lakebed known as Alathar, researchers discovered a series of fossilized footprints that date back between 112,000 and 121,000...

from the capital city of Managua, home to nearly 2 million people. Masaya is widely recognized for the persistent lava lake nestled within its Santiago crater, a feature that has earned it the ominous moniker, the “Mouth of Hell.” While the volcano has...

different paleo‑landscape. Researchers from the University of Arizona explain that the region once hosted a network of lakes and streams that later dried, allowing gypsum to accumulate and preserve the footprints for tens of millennia. Access to the...

from a Harappan habitation has been paired with its human occupation record. Earlier climate reconstructions depended on lake cores from the Thar Desert or marine sediments from the Arabian Sea, both distant from the actual settlement sites. Map of the...

2024 camping trip, amateur astronomer Joël Lapointe spotted an unexpected circular depression spanning roughly 25 km around Lake Marsal in northeastern Quebec when he examined the region on Google Maps. He forwarded the coordinates to a team of...

closest relatives. Japanese Pliocene Fossil Illuminates Early Honeybee Evolution The fossil was recovered from the volcanic‑lake deposits of the Teragi Group in Hyōgo Prefecture. Preserved in whitish, tuff‑rich siltstone, the specimen retains sufficient...

of evidence that Mars once hosted environments capable of sustaining liquid water. Prior discoveries of ancient valleys, lake deposits and hydrated minerals already indicated episodic water flow; this new study suggests that such processes may have...

Interestingly, about one‑third of these preserved brains originate from water‑logged, low‑oxygen settings such as riverbeds, lake margins, submerged caves and shipwreck sites—environments that normally accelerate decay rather than protect organic...

and thinning at an accelerating rate, according to new research into tectonic processes. The crust beneath Kenya’s Lake Turkana has been measured at a remarkably thin 13 kilometers, roughly 8 miles. While typical continental crust averages 35 kilometers...

If distracting thoughts pop up, visualize a calm, peaceful scene (like lying in a meadow or floating on a raft in a still lake). Repeat a Phrase: If you’re struggling to clear your mind, repeat a phrase such as “Don’t think, don’t think” for about 10...

redox cycles on ancient Mars. Jezero Crater on Mars has long fascinated scientists as a potential relic of an ancient lake. New data from the Perseverance rover focus on the Bright Angel formation, where iron-phosphate and iron-sulfide minerals appear...

dramatic landscapes. They were analyzing the fine-grained mudstones of the Bright Angel formation, laid down in an ancient lake or river delta. What stuck out were tiny, dark nodules—later identified as vivianite (an iron-phosphate)—and millimeter-scale...

Kenya, helping explain how one of the earliest human species lived, moved, and used tools. In northern Kenya, near today’s Lake Turkana, the land holds thick layers of ancient soil and sand. These layers were formed millions of years ago when lakes and...

its current position, Perseverance photographed a wide segment of Jezero crater, the site chosen for its presumed ancient lake and river‑delta system. The scene displays alternating strata, exposed rock faces, and features that preserve clues to Mars’...

construction of the pyramids. During the Neolithic era the Sahara was not a barren sea of sand; it featured grasslands and lakes that supported small settlements, livestock herding, and the emergence of new subsistence strategies. Archaeologists Fred...
