Anthropocene Timeline: A concise, sourced timeline of key ecological and Anthropocene-related events, from past to present.

So, I have a work related interest in developing a compact high gear reduction drive that is free of wear. As a result, and leveraging over a decade of permanent magnet machine technology development that sort of ending just shy of 25 years ago, I did some research on magnetic cycloidal drives. To me, they…

The galaxy on the screen represented an early population, but the most ancient galaxy discovered by JWST so far existed only 280 million years after the Big Bang. The telescope’s bewildering discovery of bright, early galaxies initially led some scientists to suggest that our understanding of fundamental cosmology, the laws that govern the behavior of…

Does intelligent life exist elsewhere in the universe? The question has captivated us for centuries, but despite decades of searching it remains frustratingly unanswered. Every so often a curious signal appears — fossilized structures in a meteorite, say, or an unusual gas in an exoplanet’s atmosphere — and for a moment it seems possible that…

Voyager 1 has been on an incredible journey that’s defied all expectations. And it’s about to achieve yet another milestone. The small car-sized spacecraft was the first human-made object to enter interstellar space, and for almost 50 years it’s been hurtling away from Earth at 61,100 kilometers (38,000 miles) per hour. Crazily, in all that…

For much of the early 20th century, quantum mechanics was one of the most puzzling ideas in science. The theory challenged conventional thinking and left even leading physicists struggling to make sense of its implications. A century later, it has become the foundation of technologies that influence daily life, including lasers, microchips, secure communications, and…
