The U.S. has spent more in Afghanistan than it did rebuilding Europe after World War II. Our reporter examines the missteps 鈥 and the progress 鈥 over 18 years of nation building.听
Today鈥檚 five hand-picked stories cover American influence on聽progress in Afghanistan, a challenge to the聽legitimacy of the U.S. Electoral College, the symbolism of a聽new skyscraper in South Africa, scientific聽insights from the visually impaired, and a modern-day聽movie homage to Agatha Christie.听
First, as my colleague noted here yesterday, the challenge of climate change is upon us. We can sleepwalk 鈥減ast the point of no return鈥 or we can choose 鈥,鈥 resolve, and sustainable solutions, said the United Nations secretary general Monday.
Let鈥檚 look at one ingenious step on that path: A reef rave.听
Using sound, scientists are breathing life into dying coral reefs. In 2016 and 鈥17, nearly half of the Great Barrier Reef was caused by higher water temperatures. And all marine life tends to abandon dying coral.
But British and Australian researchers put loudspeakers in 22 separate patches of dead coral and played audio recorded from living reefs. 鈥淗ealthy coral reefs are remarkably noisy places. ... Juvenile fish home in on these sounds when they鈥檙e looking for a place to settle,鈥 said Prof. Steve Simpson of the University of Exeter, one of the authors of on Friday.听
Drawn by a nightly symphony of life, the number of fish doubled over the six-week experiment. The variety of species increased by 50%. Exeter marine biologist Tim Gordon, the study鈥檚 lead author, says 鈥渁coustic enrichment鈥 isn鈥檛 a panacea. But it can help 鈥渒ick-start natural recovery processes, counteracting the damage we鈥檙e seeing on many coral reefs around the world,鈥 Mr. Gordon said via email.
What does a community of hope sound like?聽
The grunt of a cod fish. The snap of a shrimp. The whoop of a clown fish.听
