Explainer - Beyond Delta, scientists are watching new coronavirus variants

The continued spread of the SARS-CoV-2 virus has spawned a Greek alphabet of variants - a naming system used by the World Health Organization (WHO) to track concerning new mutations of the virus that causes COVID-19. Some have equipped the virus with better ways of infecting humans or evading vaccine protection. Scientists remain focused on Delta, now the dominant variant around the world, but are tracking others to see what may one day take its place.

All jokes aside, scientists find talking duck

A Dutch scientist has uncovered old recordings of a musk duck mimicking the phrase, "You bloody fool!" - learnt when it was raised by humans in an Australian bird park. Leiden University scientist Carel Ten Cate said that what was interesting about the vocal expression of the waterfowl, nicknamed "Ripper", was not so much the message, but that he could imitate humans at all.

South Korean researchers create chameleon-like artificial "skin"

South Korean researchers say they have developed an artificial skin-like material, inspired by natural biology, that can quickly adjust its hues like a chameleon to match its surroundings. The team, led by Ko Seung-hwan, a mechanical engineering professor at Seoul National University, created the "skin" with a special ink that changes colour based on temperature and is controlled by tiny, flexible heaters.

'Flying Dragon' dinosaur roamed the southern skies too, scientists say

Scientists in Chile's Atacama Desert have unearthed the fossil remains of a so-called "flying dragon," a Jurassic-era dinosaur previously known only to the northern hemisphere. The flying reptile belonged to a group of early pterosaurs that roamed the earth 160 million years ago. It had a long pointed tail, wings and sharp, outward pointing teeth.
