NASA hears from Voyager 1, the most distant spacecraft from Earth, after months of quiet

This illustration provided by NASA depicts Voyager 1. The most distant spacecraft from Earth stopped sending back understandable data in November 2023. Flight controllers traced the blank communication to a bad computer chip and rearranged the spacecraft’s coding to work around the trouble. In mid-April 2024, NASA’s Jet Propulsion Laboratory declared success after receiving good …

The day a male spear squid hatches determines which mating tactic he will use throughout his life, according to new research. Spear squid (Heterololigo bleekeri) that hatch earlier in the season become “consorts” which fight for mating opportunities. Those which hatch later become “sneakers,” which use more clandestine mating tactics. Researchers found that the mating …

Noise pollution can harm birds even before they hatch

The raucous din of modern life can seriously mess with animals (SN: 2/9/15). Traffic noise can drown out mating calls, spike stress hormones and even increase mortality. Now, new research suggests some critters can be harmed by this noise even before they can hear it. Zebra finch eggs and nestlings exposed to everyday traffic noise …
