This week’s news roundup features spiders, space and the Supreme Court. “Flying” Joro spiders are making headlines, but are they really taking over the East Coast? Extreme heat leads Greece to close the Acropolis and worry about what the rest of the summer will bring. Levels of ozone-depleting hydrochlorofluorocarbons are on the decline. Plus, satellite reentry releases ozone-damaging aluminum oxide, and access to medication abortion is preserved.  Recommended viewing: The Ozone Hole Showed Humans Could Damage Earth and That We Could Heal It E-mail us at sciencequickly@sciam.com if you have any questions, comments or ideas for stories we should cover!

‘Flying’ Joro Spiders Are No Big Deal, and Starlink Satellites Are Not So Great for The Ozone Layer

All aboard the Nathaniel B. Palmer, a research vessel making its way through the waters of West Antarctica. Journalist Sofia Moutinho is joining a team of chemists trying to find out how glacial melting is changing ocean chemistry—and what those changes might mean for the global climate. The researchers want to know whether a negative feedback loop could take shape in Antarctica’s seas. Carbon dioxide contributes to the rise in warming that is melting the glaciers. As glacial melting releases iron, phytoplankton feast. Phytoplankton in turn remove carbon from the air, potentially causing a cooling effect. Stay tuned for next Friday’s episode, where Moutinho will embark on a hunt for sea ice and hear about the researchers’ special encounter with Adélie penguins.

Could Iron from Melting Glaciers Affect Global Climate?

Nearly a third of U.S. adults have tattoos, but how many people know what's really in the ink? Despite new regulations, researchers have found many commercial inks contain unlisted and potentially harmful ingredients. John Swierk, an assistant professor of chemistry at Binghamton University, and his team are trying to figure out exactly what goes into each vial of tattoo ink—and how tattoos actually work—to help make body art safer.
