Scientists Reveal That the Red Sea Completely Vanished 6.2 Million Years Ago
New research shows the Red Sea dried out 6.2 million years ago before being suddenly flooded by the Indian Ocean. (Artist’s concept). Credit: SciTechDaily.comKAUST researchers discovered that the Red Sea experienced a massive disruption 6.2 million years ago, completely transforming its marine life.
Researchers at King Abdullah University of Science and Technology (KAUST) have confirmed that the Red Sea once completely dried up around 6.2 million years ago, only to be suddenly refilled by a catastrophic influx of water from the Indian Ocean. Their work places a precise timeline on a remarkable event that reshaped the basin’s history.
By combining seismic imaging, microfossil analysis, and geochemical dating, the team discovered that this transformation occurred within just 100,000 years, an exceptionally short span in geological terms. During this period, the Red Sea shifted from being linked to the...
Scientists Capture Rare Images of Indonesian Coelacanth
First discovered in 1997 and described as a new species two years later, the Indonesian coelacanth (Latimeria Menadoensis) is one of two living species of coelacanth, a deep-sea fish that closely resembles its ancestors from the Cretaceous period.Deep diver about a meter behind the Indonesian coelacanth (Latimeria Menadoensis) discovered at a depth of 144 m in North Maluku, Indonesia. Image credit: Alexis Chappuis.Coelacanths are a group of large, sea-cave dwelling lobe-finned fish (sarcopterygians).
They were thought to be extinct for 65 million years, until a first living specimen was discovered fortuitously in South Africa in 1938 by a South African museum curator on a local fishing trawler.
Coelacanths present several unique and intriguing features such as unpaired lobbed-fins looking much like paired fins and highly modified lungs/swim bladder.
Together with lungfish, they are the closest relatives to tetrapods...
Scientists reconstruct the tattoos of a 2,000-year-old Siberian ice mummy
From tribal symbols to the name of an ex, people have long adorned their skin with ink. Countless cultures have developed and practiced the art of tattooing for at least 5,000 years. Among the most famous examples are Ötzi the Iceman, found frozen in the Alps with 61 tattoosand the Chinchorro mummy of ancient Chile, marked with black, mustache-like dots thought to be tattoos beneath his nose.
Despite their ubiquity, ancient tattoos are difficult to study. Scientists have relied on inked-up mummies for glimpses into the early origins of the art form. But tattoos on their skin are often faded or rendered invisible by the mummification process, limiting how much researchers can glean from them.
Now, new technologies are helping bring these ancient tattoos back to life. An international team of researchers used high-resolution near-infrared photography to...
