Monkey fossils found in cave shed light on the animals" extinction centuries ago
By studying rare fossils of jaws and other skull parts of a long-extinct Caribbean monkey, a team of researchers that includes a Johns Hopkins University School of Medicine professor says it has uncovered new evidence documenting the anatomy and ecol.....»»
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,.....»»
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.....»»
How Android Users Can Minimize Blue Light’s Effects on Eye Health
As smartphones become increasingly essential for school, work, and daily life, individuals utilize mobile operating systems like Android for more efficient research, communication, and overall connectivity. In fact, a report reveals that Android co.....»»
