While a normal…

In a dry, remote stretch of central Queensland, tiny springs bubble up from deep underground to form shallow, ankle-deep pools in the middle of the desert. Living only in these springs is a fish so small it barely reaches the size of a thumbnail, called the red-finned blue-eye. It exists nowhere else on earth. For…

Two new studies published in the journal Science are reshaping what scientists understood about how dogs became so physically varied and how closely their history has tracked our own. Comparing a village dog, a toy poodle, and a mastiff makes clear just how extreme the physical range within a single species can be. Roughly 700…

For years, scientists believed these…

From a great distance, the planet could easily give the wrong first impression. Seen in visible light, it appears as a rich blue world, bringing to mind the familiar colour of Earth as viewed from orbit. Yet the resemblance ends almost immediately. Instead of oceans reflecting sunlight, this distant planet is wrapped in an atmosphere…

Giant sequoias (Image Credit: Canva) California’s giant sequoias have stood tall for thousands of years, surviving droughts, storms and countless natural fires. Yet, in just two wildfire seasons, these ancient giants suffered unprecedented losses. Between 2020 and 2021, record-breaking wildfires are estimated to have killed nearly 17% of the world’s mature giant sequoias, roughly one…

Still, the outlook for Hawaii’s snails is uncertain, symbolizing a new era in the conservation of endangered species. In 1955, wildlife officials in Hawaii released a meat-eating “cannibal” snail to control an invasive pest. But the plan went terribly wrong. Instead of eating the pest, the predator turned on the islands’ rare native tree snails,…

The night sky has inspired people for thousands of years, but scientists now say it could look very different in the future. The researchers at the European Southern Observatory (ESO) warn that ambitious plans to launch huge numbers of satellites into Earth’s orbit could make the night sky much brighter than it is today.While many…
