According to Australian news outlet ABC, Matt Waller, a tour operator in Neptune Bay, discovered that great white sharks act more calmly when listening to music by AC/DC, the Aussie heavy-metal band that reached its peak during the 1980s. The two songs favored by the sharks: “You Shook Me All Night Long” and “Back in Black.”
After Waller played the songs using underwater speakers, the sharks became “more investigative, more inquisitive and a lot less aggressive.”
“They actually came past in a couple of occasions when we had the speaker in the water and rubbed their face along the speaker which was really bizarre,” he said.
By using music and not bait to attract sharks during tours, his company is helping cage-diving operations become more eco-conscious and environmentally sustainable.
What is the universe made of? We only know a tiny fraction — 4 percent — of the answer. From our little corner of the cosmic map, how do we know what else is out there? Luckily, we have space messengers (otherwise known as cosmic rays) that bring us data from parts of the cosmos far beyond our reach. Veronica Bindi explains how cosmic rays transmit information about our universe from the great beyond.
At GE’s MRI magnet factory in Florence, SC, Robin works on the wiring of a 3 Tesla magnet by winding copper and niobium titanium wires along its interior. Each 3T magnet contains over 125 miles of wiring. This wiring is so strong that a single strand has enough strength to lift a car. Photo by @seenewphoto.
