The Great Barrier Reef Has Lost Half Its Corals
The Great Barrier Reef, one of the earth’s most precious habitats, lost half of its coral populations in the last quarter-century, a decline that researchers in Australia said would continue unless drastic action is taken to mitigate the effects of climate change. From a report: Researchers studied coral colonies along the length of the reef between 1995 and 2017 and found…
Algae transplant could protect coral reefs threatened by warming seas
Heat-resistant algae made in a lab seems to protect coral from bleaching. It could help to save reefs if we fail to tackle global warming fast enough Source: https://www.newscientist.com/article/2243348-algae-transplant-could-protect-coral-reefs-threatened-by-warming-seas/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…
The Great Barrier Reef has suffered its most widespread bleaching yet
Australia’s record-breaking heatwave early this year bleached 60 per cent of the Great Barrier Reef, affecting all three of its regions for the first time Source: https://www.newscientist.com/article/2239957-the-great-barrier-reef-has-suffered-its-most-widespread-bleaching-yet/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…
Great Barrier Reef Suffers Its Most Widespread Mass Bleaching Event On Record
An anonymous reader quotes a report from The Washington Post: Surveys conducted by scientists at Australia’s James Cook University and the Great Barrier Reef Marine Park Authority show that a summer of extreme heat has caused the reef, which is a World Heritage Site, to suffer a mass bleaching of unprecedented scale. Corals from the far north to the southern tip…
Can We Save Coral Reefs Using Underwater Loudspeakers?
“The desperate search for ways to help the world’s coral reefs rebound from the devastating effects of climate change has given rise to some radical solutions,” reports the Washington Post. There’s coral “nurseries” in the Caribbean, while Hawaiian scientists are trying to breed a new and more resilient type of coral. But at least one team focused on the herbivorous fish…
North Taurid meteors to peak in moonlight
Slow-moving North Taurids don’t exhibit a sharp peak, so meteor rates may remain fairly steady for the next several days. Too bad about the moon! Source: https://earthsky.org/astronomy-essentials/north-taurid-meteors-on-november-nights…
Chemists Discover Water Microdroplets Spontaneously Produce Hydrogen Peroxide
An anonymous reader quotes a report from Phys.Org: Stanford researchers report Aug. 26 in Proceedings of the National Academy of Sciences that microscopic droplets of water spontaneously produce hydrogen peroxide. The discovery could pave the way for greener ways to produce the molecule, a common bleaching agent and disinfectant, said Richard Zare, the Marguerite Blake Wilbur Professor in Natural Science and…
New 60-Mile Pumice Raft Could Help Restore Australia’s Great Barrier Reef
“A huge raft of pumice created by an underwater volcano is floating toward Australia, and it could help the Great Barrier Reef recover from bleaching,” reports Weather.com: The pumice raft is about 60 square miles — almost as big as Washington D.C. Scientists say it was formed earlier this month by an underwater volcano near Tonga, some 2,000 miles east of…
