Hello, I’m Scott Hershberger, with Scientific American as an American Affiliation for the Development of Science Mass Media Science and Engineering Fellow. And right here’s a brief piece from the September 2020 subject of the journal, within the part referred to as Advances: Dispatches from the Frontiers of Science, Know-how and Medication. The article is titled “Quick Hits,” and it’s a rundown of some tales from across the globe.
The earliest dinosaurs laid soft-shelled eggs, paleontologists say. A brand new chemical evaluation of a greater than 200-million-year-old fossilized egg from Patagonia—and a clutch of newer eggs from Mongolia, discovered within the Gobi Desert—revealed a skinny movie matching the traits of recent soft-shelled eggs.
Archaeologists discovered that 20 deep shafts, beforehand considered pure sinkholes and ponds, have been dug by Neolithic people. The shafts kind a circle two kilometers in diameter, with the Durrington Partitions monument at its heart, simply three kilometers from Stonehenge.
Researchers documented the biggest lightning bolt ever recorded. The “mega-flash,” which prolonged for greater than 700 kilometers in southern Brazil in 2018, was detected by a brand new superior climate satellite tv for pc in geostationary orbit.
Researchers sequenced DNA samples from the Dead Sea Scrolls, figuring out fragments produced from sheep pores and skin and others produced from cow disguise. The method might assist match fragments collectively and unravel the artifacts’ geographic origins.
Scientists recognized an elusive nose-horned dragon lizard within the forests of North Sumatra. Regardless of showing within the mythology of the indigenous Bataks, the visually hanging species had been noticed by scientists solely as soon as earlier than—nearly 130 years in the past.
And from Australia:
Submarine drones uncovered an in depth system of underwater “rivers” of dense, salty water alongside Australia’s continental shelf. These flows carry natural matter from the coast into the deep ocean, and their quantity varies seasonally, peaking in winter.
That was “Fast Hits.” I’m Scott Hershberger.
