Q&A: Researchers examine link between light pollution and interest in astronomy
Picture walking outside on a dark, cloudless evening. You look up to admire the stars—maybe even a planet, if you're lucky—and a sense of wonder washes over you. New research from the University of Washington shows this might be more than a memor.....»»
Influence of a black hole"s spin: First evidence of precession in ultraluminous accretion disks
Gas swirls around a black hole due to its intense gravity, forming an accretion disk. These accretion disks, being among the most efficient energy conversion mechanisms in the universe, emit light and plasma jets. When a black hole spins on its axis,.....»»
Bottlenose dolphins "smile" at each other while playing, research shows
Dolphins are extremely playful, but little is known about how they—and other marine mammals—communicate during playtime. New research published October 2 in the journal iScience shows that bottlenose dolphins (Tursiops truncates) use the "open mo.....»»
Scientists decode brain mechanisms of stopping in Drosophila
Ever wish you could stop that fruit fly on your kitchen counter in its tracks? Scientists at Max Planck Florida Institute for Neuroscience have created flies that halt under red light. In doing so, they discovered the precise neural mechanisms involv.....»»
Q&A: Using a new approach to shine a light on hidden plant microbes
Despite there being more microbes on Earth than stars in our galaxy, only a tiny fraction have been discovered. An approach called metagenomics—a type of DNA sequencing—may help scientists learn more about these elusive organisms, according to Pe.....»»
