SpaceX President and COO Gwynne Shotwell and her husband have announced that they are donating ~$325 million of SpaceX stock to Trump Accounts for more than two million children across the U.S.
Every one of those kids will now have a direct stake in a company whose mission is the most ambitious in human history: to make life multi-plantary 🚀
An octopus may be the closest thing we have on Earth to an alien life form. 🐙
Octopuses just passed a remarkable cognitive test: they can use mirrors to locate hidden prey, the first time this ability has been shown in any invertebrate.
In a new study, California two-spot octopuses (Octopus bimaculoides, sometimes called a 'bimac') were trained to understand mirror reflections. When shown a virtual crab in a mirror (with the real stimulus hidden behind them), the octopuses didn’t attack the reflection. Instead, they turned 180 degrees or climbed over barriers to reach the actual location — succeeding about 73% of the time.
Researchers used a projected virtual crab to eliminate chemical cues, forcing the animals to rely purely on visual-spatial reasoning. The octopuses also got faster at solving the task over time, suggesting they built an internal spatial map in their memory.
Not bad for creatures related more closely to clams than to vertebrates.
