We also provide data for ten humans moving in time to the same stimuli using a comfortable arm motion with similar amplitude. This sea lion’s sensorimotor synchronization was precise, consistent, and indistinguishable from or superior to that of typical adults. These findings challenge claims of unique neurobiological adaptations for beat keeping in humans.”

WELCOME TO HOWTOWN! Our small but mighty team (Joss Fong and Adam Cole) digs into the evidence behind commonly held facts and claims in the news. This month: we’re about to mine one of the most unexplored places on Earth — and it turns out, it’s not a desert. It’s an alien zoo.
Check out Johnny’s episode on the fascinating fight over deep sea mining: • The Trillion $$$ Fight Over Tiny Ocean Rocks

Tidal energy is one of the oldest forms of renewable power, dating back over 1,400 years to early tide mills. But despite centuries of promise, tidal power still provides a tiny fraction of the world’s electricity. Why?
In this video, we explore the engineering behind tidal range and tidal stream technologies, visit the University of Southampton’s towing tank to see how modern turbines are tested, and look at the projects currently being built in the UK that could finally scale this technology.
We’ll cover the pros—predictability, energy density, low emissions—and the very real challenges—cost, complexity, and limited viable locations. Can tidal power ever compete with wind and solar, or will it remain a niche solution?
If you would like to help develop the Engineering with Rosie channel, you could consider joining the Patreon community, where there is a chat community (and Patreon-only Discord server) about topics covered in the videos and suggestions for future videos and production quality improvements. / engineeringwithrosie
