Asian Stocks Rise, US Futures Gain After Warsh: Markets Wrap - SWI swissinfo.ch

Archaeologists working at an ancient burial complex in Peru have uncovered remarkable evidence of hairless dogs that lived more than 1,200 years ago, long before the rise of the Inca Empire. The discoveries include naturally mummified remains, unusual skeletal features, and clues about what the animals ate and how they were treated by the people around them. Peruvian hairless dogs are a distinctive Indigenous breed known for their slender bodies, pointed ears, and lack of fur. They frequently appear in pottery created by ancient societies along the Andean coast. Today, a variation of the breed is recognized by the American Kennel Club as the Peruvian Inca Orchid. The dogs are also an important national symbol, having been officially designated part of Peru's cultural heritage in 2000.

Our early Earth was a heavy metal album cover: a molten ball covered in a global lava ocean, spewing lethal gases while being pelted by the flaming space-rocks of our Solar System's violently chaotic afterbirth. Over the next 4.5 billion years of hectic cosmo-geological time, it has settled down a bit, allowing humans, lemurs, and others to emerge. A vision of this hellish ancient reality remains, (hopefully) never to be glimpsed by human eyes: our molten metallic core, blazing about as hotly as the surface of the Sun. But our core constantly sends chemical messengers up through its layers, including the space-borne ingredients of its birth, locked away for about one-third the lifetime of the Universe. This includes the hydrogen that was drawn in from the giant cloud of gas and dust that formed the Sun, which continues to ooze up from the core and turns into water in the mantle and crust – not a splashy-sloshy water, but a water trapped in minerals. Early Earth may have looked something like this.

About 99 million years ago, a tiny insect became trapped in tree resin with mouthparts nearly twice the length of its body. The resin hardened into amber, preserving an unusual feeding organ that researchers think could bend through narrow cracks in tree bark to reach sap. The newly described species, Cretodorus noonoo, takes its name from Noo-Noo, the friendly vacuum cleaner in the children’s television series Teletubbies. The character’s long, flexible hose resembles the ancient insect’s mouthparts. Long mouthparts, little evidence of pollinationNoo-Noo belonged to Neazoniidae, an ancient family of planthoppers. In a study published in the journal Insects, researchers examined fossils from this family, including 13 specimens preserved in Kachin amber from Myanmar. Their living relatives use mouthparts shaped like a simple needle to pierce plant tissues and suck out fluids. An amber fossil of a Neazoniid planthopper.
