Robot Hand

[SciTech Era @SciTechera]

China unveils robot hand that extends 3.5 times farther than human hand 👀

- They unveiled a robot prototype that can outperform human hand in certain movements, extending and contracting 3.5 times farther than a human hand.

- Called BioflexBot, the robot combines a coiled spring, a flexible outer shell and compressed air to enable dexterous movements.

- It can pinch, rotate, hook and grasp objects, with potential applications in laboratories and confined environments.

What does a total solar eclipse look like from space?

Taken from the Mir Space Station #OTD in 1999, this photo shows the Moon's shadow on Earth during a total solar eclipse.

American pika - a dear little creature whose home range is under threat from #ClimateChange

[US Department of the Interior @Interior]

This American pika isn't picking flowers for decoration. It's building a haystack.

All summer long, pikas gather grasses, wildflowers and other plants, carrying mouthful after mouthful back to its home. They spread the plants out to dry in the sun, then stash them away for the long alpine winter.

Where the term”debugging “ came from

[Physics In History @PhysInHistory]

In 1947, the Harvard Mark II was completed. One of its key operators was Grace Hopper, a pioneering computer scientist. She popularized the term debugging after an actual moth was found causing issues in the system.

[Science Advances @ScienceAdvances]

Not only do catnip and silver vine hold a special place in felines’ hearts, but the intoxicating chemicals in these plants also protect cats from mosquito bites, according to research from 2021.

[News from Science @NewsfromScience]

Whereas dogs’ grins and grimaces often portray what they’re feeling, cats’ moods can be inscrutable, even to their owners.

A 2019 study shows that cats do in fact have facial expressions—humans just aren’t that good at interpreting them. Learn more on #InternationalCatDay: https://t.co/MIZToBllAm

Osprey, with prey

[Ocean Conservancy @OurOcean]

Have you ever seen a sleek brown-and-white bird hover over the ocean, fold its wings and drop into the water like a cannonball, only to surface seconds later with a fish in its grip? 😳

If so, you've probably seen an osprey! Learn all about these water-loving birds of prey:

🧵 Interesting thread: #AI Is Not Just a Tool

[IntegralAnswers @IntegralAnswers]

1/ AI Is Not Just a Tool

Yuval Noah Harari’s most important warning about AI is not that humanoid robots will suddenly take over the streets.

It is that civilization itself runs on language.

Laws, contracts, financial markets, religions, political systems, media and bureaucracies are all constructed and operated through words, symbols and shared narratives.

The printing press could reproduce words, but it could not decide what to print. An atomic bomb could destroy a city, but it could not choose its target.

AI is different. It can increasingly interpret information, generate ideas, make decisions and act inside the systems humans created.

That makes AI more than a passive tool. It is becoming an agent within the operating system of civilization.

The transition may not look like a machine overthrowing humanity. It may look like control gradually moving toward systems that understand law, finance, media and bureaucracy better than the humans nominally responsible for them.

Would love to know where this is. We used to swim regularly with a school of Heller’s barracuda off Hawaii’s Kohala coast — but the school was maybe one-third the size of the one pictured here
