Subtle shifts in stellar signals reveal pervasive waves from mergers of giant black ho
Scientists are learning how to cryopreserve living tissues, organs, and even whole organisms, then bring them back to life
Science Staff Writer Adrian Cho joins host Sarah Crespi to talk about plans for the next generation of gravitational wave detectors—including one with 40-kilometer arms.
The proposed detectors will be up to 10 times more sensitive than current models and could capture all black hole mergers in the observable universe.
Sarah also talks with Pavani Cherukupally, a researcher at Imperial College London and the University of Toronto, about her Science Advances paper on cleaning up oil spills with special cold-adapted sponges that work well when crude oil gets clumpy.
First up, host Sarah Crespi talks with Staff Writer Adrian Cho about new gravitational wave detections from the first half of 2019—including 37 new black hole mergers. With so many mergers now recorded, astrophysicists can do different kinds of research into things like how new pairs of black holes come to be and how often they merge.
Sarah also talks with Sarah Davidson, data curator at the Max Planck Institute of Animal Behavior, about results from an Arctic animal tracking project that includes 3 decades of location information on many species, from soaring golden eagles to baby caribou taking their first steps. The early results from the Arctic Animal Movement Archive show that researchers can use the database as a baseline for future Arctic investigations and to examine the effects of climate on ecosystems in this key region.
In 2015, the Laser Interferometer Gravitational Wave Observatory (LIGO) facilities in the US directly detected ripples in space-time known as gravitational waves. These waves were produced by the final spiral of two oribiting black holes that smashed into each other, sending ripples across the universe.
In this Podcast Extra, Benjamin Thompson speaks to Cole Miller from the University of Maryland about the quest to detect gravitational waves, which were first hypothesised by Albert Einstein back in 1916.
