The Spark Of Life In Space And 1.7 Billion T. Rexes

Here’s our weekly compilation of the most interesting science stories from the previous few days and a few intriguing articles to keep you occupied during the weekend. One of them is that The Spark Of Life In Space And 1.7 Billion T. Rexes.

It’s been a busy week for animal-related science news. We learned why a small jumping spider is such a terrible guy, updated our best estimates of how many T. rexes formerly roamed the planet, and learned how the Australian government is battling chlamydia in koalas.

In other news, researchers are perplexed by a strange sound from 70,000 feet (21,000 meters) up in the atmosphere. Meanwhile, the James Webb Space Telescope has discovered what may be an ancient “water world” in a nearby star system.

A 5,400-year-old Spanish tomb that exactly depicts the summer solstice, 2,300-year-old scissors, a “folded” sword, and the foundations of a Roman watchtower in Switzerland are discoveries that are closer to home.

We discussed the most recent research on our ancestors, which indicated that Neanderthals left their tall noses behind for modern humans to inherit. Further investigation revealed evidence that solar superflares may have been the motivation for the emergence of life on Earth. This vibrant image of Earth signals the onset of El Nio in the Pacific Ocean.

The image depicts Kelvin waves (red and white, for warmer water and higher sea levels, respectively) traveling over the Pacific using NASA’s Sentinel-6 Michael Freilich satellite information. When these waves originate at the equator and transport the warm upper layer of water to the western Pacific, scientists believe they are a prelude to El Nio.

Josh Willis, a project scientist at NASA’s Jet Propulsion Laboratory (JPL), stated, “We’ll be watching this El Nio like a hawk.” “The world will experience record warming if it’s big”.
