Explainer – Beyond Delta, scientists are observing 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 new mutations in the virus that causes COVID-19. Some have provided the virus with better ways to infect people or evade vaccination protection. Scientists continue to focus on Delta, which is now the world’s dominant variant, but are tracking others to see what might one day take its place.

South Korean researchers create chameleon-like artificial “skin”

South Korean researchers say they developed an artificial skin-like material, inspired by natural biology, that can quickly adapt its hues to its surroundings, like a chameleon. The team, led by Ko Seung-hwan, a mechanical engineering professor at Seoul National University, created the “skin” with a special ink that changes color depending on the temperature and is controlled by tiny, flexible heating elements.

The “Flying Dragon” dinosaur also roamed the southern skies, scientists say

Scientists in the Chilean Atacama Desert have unearthed the fossil remains of a so-called “flying dragon”, a dinosaur from the Jurassic period that was previously only known to the northern hemisphere.
