bats – Southern Fried Science

I’m Andrew Thaler and I build weird things.

Last month, while traveling to Kuching for Make for the Planet Borneo, I had an idea for the next strange ocean education project: what if we could use bone-conducting headphones to “see” the world like a dolphin might through echolocation?

Bone-conducting headphones use speakers or tiny motors to send vibrations directly into the bone of you skull. This works surprisingly well for listening to music or amplifying voices without obstructing the ear. The first time you try it, it’s an odd experience. Though you hear the sound just fine, it doesn’t feel like it’s coming through your ears. Bone conduction has been used for a while now in hearing aids as well as military- and industrial-grade communications systems, but the tech has recently cropped up in sports headphones for people who want to listen to music and podcasts on a run without tuning out the rest of the world. Rather than anchoring to the skull, the sports headphones sit just in front of the ear, where your lower jaw meets your skull.

This is not entirely unlike how dolphins (and at least 65 species of toothed whales) detect sound.

Fog Horn (A Call to Action)

Hurricane Harvey has passed, but its impacts will continue to be felt for years to come. There’s lots of great organizations to donate to, but in the immediate aftermath,it’s often best to donate to local relief programs that already have a ground team in place, rather than national groups that will take weeks to build up their infrastructure. I’m a fan of the Texas Diaper Bank and Portlight Inclusive Disaster Strategies, both of which serve communities that tend to be particularly vulnerable during natural disasters.

Flotsam (what we’re obsessed with right now)

It will take months, if not years, to fully understand the impacts of Hurricane Harvey, which already looks to be the costliest storm in US history. These drone videos give you some idea of the sheer scale of the damage. The Washington Post has an interactive map to help visualize what the equivalent deluge would look like around the world: What the Harvey deluge would look like where you live.
