"Politicians and nonprofit groups have blamed offshore wind turbines for whale deaths, but the science doesn’t support those claims—at all"

"Conducting necropsies on beached whales to pin down a cause of death is made difficult by the animals’ layer of blubber and by the fact that organs can literally cook inside a stranded whale. But it is starkly clear that human activity—in the form of ships that hit whales or fishing gear that wraps around them—is often to blame."

"I recently explored the optimal fuel burn schedule to land as gently as possible and with maximum remaining fuel. Surprisingly, the theoretical best strategy didn’t work. The game falsely thinks the lander doesn’t touch down on the surface when in fact it does. Digging in, I was amazed by the sophisticated physics and numerical computing in the game. Eventually I found a bug: a missing “divide by two” that had seemingly gone unnoticed for nearly 55 years."

An interesting read. "A group of prominent biologists and philosophers announced a new consensus: There’s “a realistic possibility” that insects, octopuses, crustaceans, fish and other overlooked animals experience consciousness." https://www.quantamagazine.org/insects-and-other-animals-have-consciousness-experts-declare-20240419/

A quasi-satellite of Venus has just received an unusual name.

On July 19, 1952, Palomar Observatory was undertaking a photographic survey of the night sky. Part of the project was to take multiple images of the same region of sky, to help identify things such as asteroids. At around 8:52 that evening a photographic plate captured the light of three stars clustered together. At a magnitude of 15, they were reasonably bright in the image. At 9:45 pm the same region of sky was captured again, but this time the three stars were nowhere to be seen. In less than an hour they had completely vanished.

Has anyone seen it in these locations? Or planning? The IMAX Dome Theatre in Detroit is already sold out.
