Lichens are in peril because they adapt so slowly to climate change

Lichens are important for stabilising soils and providing some animals with food, but the algae within them are adapting to climate change at a rate of just 1°C every million years Life 15 February 2022 By Jake Buehler Lichen (Folmannia orthoclada) on rock in Atacama Desert.

Behold, The Most Accurate Virtual Simulation of Our Universe to Date

In the Cosmic Calendar, which maps the chronology of the Universe across a single Earth year, modern humans don’t appear until the very last minute of December 31. Everything we understand about the evolution of the Universe, we’ve had to piece together. We simply haven’t been around for pretty much any of the 13.7 billion-year … Read more

Weird, Extinct Animal Species Identified in First Such Finding in Over 100 Years

Peering back hundreds of millions of years into the past can turn up some astonishing findings – as it has with the discovery of a second species of opabiniid, a soft-bodied arthropod with a segmented exoskeleton that lived on the seafloor during the Miaolingian (509-497 million years ago).   The original opadiniid, Opabinia regalis, was … Read more

Exoplanet evolution? Mini-Neptunes may shed their atmospheres and become super-Earths

New research suggests that stellar radiation is stripping away the “fluffy” atmospheres of exoplanets slightly smaller than Neptune, leaving behind their rocky cores and transforming them into worlds more closely resembling Earth.  In the 1990s, astronomers confirmed the existence of planets outside the solar system. Known as exoplanets, they are one of the most fascinating … Read more

Most flying robots, whether they use wings or … Read more

Animal intelligence: Fruit flies’ learning styles may not be dictated by nature or nurture alone

Genetically identical fruit flies raised in the same environment still learn at different rates, suggesting that random differences in brain development may have evolved to produce variation in a species Life 2 February 2022 By Christa Lesté-Lasserre Fruit flies may have random variance to account for different learning styles Aleksandar Kitanovic / Alamy Genetically similar … Read more

Teeny Tiny 500-Million-Year-Old Fossils Could Help Explain The Evolution of Spiders

Two tiny fossils, each smaller than an aspirin pill, contain fossilized nerve tissue from 508 million years ago. The bug-like Cambrian creatures could help scientists piece together the evolutionary history of modern-day spiders and scorpions.    Still, it’s not clear exactly where these fossils – both specimens of the species Mollisonia symmetrica – fit on the arthropod … Read more

Bat evolution: Subtle change to inner ear bone distinguishes two major groups
