is a citizen science project (and app) enabling you to listen to livestreams of audio from underwater microphones off Washington’s San Juan Island.
Mostly, you'll hear ships moving through Haro Strait and other boats in the area. But if you listen long enough, you might be treated to some whale song. From Atlas Obscura
(Lead researcher Scott) Viers developed OrcaSound because he saw an opportunity for engaged citizens to help fill gaps in the study of orcas. The whales have long been well-observed in the summertime, when the weather cooperates and the cetaceans are more accessible to scientists and the Coast Guard, who observe them by boat. But questions have lingered about their lives during other times of the year. Now, in any season, listeners can notify scientific authorities to alert them to the presence of whales, so they can rush out like first responders to collect important data. The orcas have been facing a food crisis in recent years, so their fecal matter can help scientists get a sense of what they’re managing to eat, and what their stress levels are like. Having citizens on the line is also an exercise in preparing for the worst, like an oil spill. In such a case, there will be multiple (ear) witnesses to attest to where the whales were at the time.

I’ve had quite a few fun afternoons playing with dry ice from making spooky fog in the kitchen to exploding plastic bottles in the yard. But I’ve never had the opportunity to pour hot lava over dry ice. In this video, the lava is 1400 °C and the dry ice is -78C°. So cool! And […]
A Boston University team have developed an acoustic, 3D-printed metamaterial whose topology is such that it reflects 94% of human-audible sound; the researchers' demonstration involves inserting a ring of this stuff in a PVC pipe and blasting a speaker down one end: light and air emerges from the other end, but sound does not.
Scientists Lior Appelbaum and David Zada in Israel publish new proof that sleep serves to help our brains repair damage.
Despite government legislation and improving caller ID technology, robocalls and scam artists are rampant on the phone lines – up to 35 billion a year in the US alone. They can be annoying at best and a financial threat at worst, but there’s a way to take security into your own hands. One good example […]
