00:49 The search for animals’ magnetic sense sufferers a potential setbackExactly how animals sense Earth’s magnetic field has long eluded researchers. To understand it, many have turned to the fly model Drosophila melanogaster, long thought to be able to detect magnetic fields. However, a recent Nature paper has raised questions about this ability, a finding that could have repercussions for scientists’ efforts to understand the mechanism behind magnetic sensing, one of the biggest questions in sensory biology.

13:03 An iconic observatory shuts downThis week the famed Arecibo Observatory in Puerto Rico shut down. The facility’s main telescope collapsed in 2020 and the site has since been battered by storms and pandemic-related shutdowns. Now, with funding exhausted and no clear plan in place, scientists are wondering what will become of the site.

The deep haunting tones of the world's largest animals, baleen whales, are iconic - but how the songs are produced has long been a mystery. Whales evolved from land dwelling mammals which vocalize by passing air through a structure called the larynx - a structure which also helps keep food from...
