Underwater Loudspeakers Make Fish Flock to Dead Coral in Radical Experiment Underwater Loudspeakers Make Fish Flock to Dead Coral in Radical Experiment
- December 03, 2019

It's a "promising" result for management of the problem on a "local basis", though we as a planet still need to solve the problems that led to coral reef degradation in the first place. The acoustically enriched reefs attracted fish faster and maintained them longer than the reefs without a healthy soundtrack, according to the study . (more...)

Newly discovered black hole is so large, it shouldn't exist Newly discovered black hole is so large, it shouldn't exist
- December 01, 2019

Bregman said scientists are always trying to learn more about the birth and death of stars, and the discovery of one as large as LB-1 could inform that process. Previously, scientists thought they could be about 20 times the mass of the sun. Because stellar black holes are so hard to identify, about two dozen of them were measured. (more...)

Greenhouse gases accelerate to new peak in 2018, U.N. says Greenhouse gases accelerate to new peak in 2018, U.N. says
- November 28, 2019

The U.N. agency's Greenhouse Gas Bulletin is one of a series of studies to be published ahead of a U.N. climate change summit being held in Madrid next week, and is expected to guide discussions there. "Support then, the temperature used to be 2-3C warmer, sea level used to be 10-20m bigger than now", said Mr Taalas. So it's fitting that even on a day when there's a bit of good news about coal's decline, we also learned that greenhouse gases in the atmosphere hit a new peak. (more...)
