Extinction: A million species at risk, so what is saved?

2019-12-28 06:56:56

A decade-long project to save one of the world's most endangered birds has finally found success, with the birth of two chicks. But with an estimated one million species at risk across the world, and nothing like the money and resources to save them all, how do conservationists choose the few they can save?

Brain-inspired computing could tackle big problems in a small way

2019-09-26 06:21:30

While computers have become smaller and more powerful and supercomputers and parallel computing have become the standard, we are about to hit a wall in energy and miniaturization. Now, researchers have designed a 2D device that can provide more than yes-or-no answers and could be more brain-like than current computing architectures

Machu Picchu: Ancient Incan sanctuary intentionally built on faults

2019-09-26 06:16:17

The ancient Incan sanctuary of Machu Picchu is considered one of humanity's greatest architectural achievements. Built in a remote Andean setting atop a narrow ridge high above a precipitous river canyon, the site is renowned for its perfect integration with the spectacular landscape. But the sanctuary's location has long puzzled scientists: Why did the Incas build their masterpiece in such an inaccessible place?

Biggest Black Hole Blast Discovered: Most Powerful Quasar Outflow Ever Found

2012-11-29 06:55:21

Astronomers using ESO's Very Large Telescope (VLT) have discovered a quasar with the most energetic outflow ever seen, at least five times more powerful than any that have been observed to date. Quasars are extremely bright galactic centres powered by supermassive black holes. Many blast huge amounts of material out into their host galaxies, and these outflows play a key role in the evolution of galaxies. But, until now, observed quasar outflows weren't as powerful as predicted by theorists.
