Sixty-three military data-relay satellites now circle the Earth for the Pentagon's newest space network — half of the planned constellation — and the optical…
A 2025 MIT-led study estimates that current AI tools overlap with skills representing 11.7 per cent of the United States wage bill, or roughly $1.2 trillion a year.

On the night of 9 October 1946, observers across parts of Europe and North America watched the sky above the constellation Draco erupt.
A gray wolf's bite generates roughly 1,200 pounds per square inch — nearly double a German shepherd's — and the jaw geometry that makes it possible is arranged around one specific job: cracking the bones of animals ten times its own weight.
A snapping shrimp does not need to touch what it kills. It cocks one oversized claw, holds it under tension, and releases; the claw shuts in well under a millisecond.
