Ten years ago, sunflower sea stars faced near extinction due to a devastating marine epidemic, leading to unchecked sea urchin populations that destroyed essential kelp forests. Recently, a newly identified colony of these sea stars has rekindled hope for ecological restoration. Researchers are examining their resilience to diseases, which could greatly benefit efforts to reintroduce these vital predators to their ocean habitats.from Science News: Fresh Discoveries, Research & Breakthroughs https://ift.tt/WreoOZt
New research confirms dogs can differentiate human emotions through facial expressions. Their brains process happy faces in a unique reward region, showing emotional significance. Dogs also distinguish between fear, anger, and sadness with distinct brain activity patterns. This ability developed through domestication, aiding their social understanding of humans. Understanding these emotions does not mean dogs experience them identically to people.
On August 12, 1960, NASA launched Echo 1A, a 100-foot balloon that became its first successful communications satellite. The passive spacecraft reflected telephone, radio and television signals between distant points on Earth. It also helped NASA study atmospheric density, solar pressure and satellite triangulation before re-entering Earth’s atmosphere in 1968.
