"Shipworms" are a menace, devouring the wood in ships and docks. For a while, as the New York Times explains, the pollution in New York harbor actually had some benefit in fighting them:
By the 1960s, the waters had become overrun with raw sewage and oil and chemicals discharged by factories. “Industries were using the harbor as a dumping ground,” Mr. Goldstein said. “You wouldn’t want to swim or eat the fish, and only the bravest would take out a kayak.”
Indeed, there were stories of boats being taken into the polluted harbor just to clean off any marine borers from other waters.
The good news is New York waterways are increasingly clean thanks to laws like the the 1972 Clean Water Act. But the bad news is the clean water has allowed marine borers to flourish:
Marine borers took out a heavily used Brooklyn footbridge over Sheepshead Bay in 2015, requiring the city to close it for several months to repair a hole-ridden foundation. The borers have also weakened timber pilings under the Carroll Street Bridge over the Gowanus Canal in Brooklyn, and under the F.D.R. Drive in Manhattan.
Along the New Jersey waterfront their handiwork led most notably to the partial collapse of a pier at Frank Sinatra Park in Hoboken.
Now the city is spending massive amounts to fight the pests, including $114 million to coat the 11,000 timber pilings under Brooklyn Bridge Park with epoxy.

Researchers successfully revived ancient microbes, some more than 100 million years old, that were buried in the seafloor. During an expedition to the South Pacific Gyre, the scientists from the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) and their colleagues drilled into the ocean sediment almost 6,000 meters below the surface. “Our main question […]
My family stopped wiping down all our groceries to “disinfect” them a couple months ago, mostly because of hygiene exhaustion. Then in May, the Center for Disease Control and Prevention clarified its own Web page about how COVID-19 spreads to state that “based on data from lab studies on COVID-19 and what we know about […]
I’d totally go.
“The way to have power is to take it.” — Boss Tweed. We think an 18th-century political power broker probably had a different definition of power in mind when he made that statement, yet the sentiment still applies. We’ve all got devices all but falling out of our pockets and the need for power to […]
If the last 50 years of education have taught us nothing else, it’s that it often requires different tactics to best reach different learners. To pick up a foreign language, some students take best to the old-school high school language lab method, using heavy repetition, verb conjugation and grammar emphasis to embed a new language. […]
For those who want a career in video games, there’s no reason to sit around and wait. EA and Rockstar Games probably aren’t going to seek you out and knock on your door with a job opportunity. But if you’re an indie developer with a good idea and some passion, you can create a really […]
