A coal mine can degrade its local environment. But a fungus may inadvertently help clean up the mine—with its own waste products.Researchers worked with a fungus called Stilbella aciculosa. As it makes spores, it also produces superoxide. That's a highly reactive kind of oxygen. When the released superoxide bumps into the mineral manganese in the environment, it makes that mineral much more reactive itself. The pepped-up manganese then grabs and holds a variety of toxic metals and other substances that need to be cleaned up and taken out of coal mine drainage water.The research, led by Colleen Hansel of Harvard and the Woods Hole Oceanographic Institution, appears in the Proceedings of the National Academy of Sciences. It's been known that various bacteria and fungi can help in environmental remediation.

AI explanationShows the answer. Tap to open.

Printed "faculty", the speaker says "inadvertently"

Explanation: In the audio you hear "may inadvertently help". They start with different letters, and the spoken word is much longer.

Printed "juices", the speaker says "produces"

Explanation: Here the speaker says "also produces superoxide". They end the same, so listen to the beginning of the word.

Printed "putrefactive", the speaker says "reactive"

Explanation: The speaker says "a highly reactive kind", not "putrefactive". "putrefactive" makes no sense before "kind of oxygen".

Printed "fierier", the speaker says "bacteria"

Explanation: Listen for "various bacteria and fungi". They start with different letters, so hear the whole word.

"Stilbella" matches the audio

Explanation: "a fungus called Stilbella aciculosa" has an uncommon name. It looks tricky, but the speaker says it exactly as printed, so do not click it.

"manganese" matches the audio

Explanation: "the mineral manganese in the environment" contains a long word that may look wrong. The speaker pronounces it exactly as printed, so do not click it.
