The Computer at the Bottom of a Canal
Somewhere at the bottom of the Forth and Clyde Canal, buried in the silt, there is a box of custom silicon that was right about almost everything. Back in 1988 a Scottish hi-fi company shipped a processor that checked the type and bounds of every memory access in hardware, garbage-collected its own heap in silicon, […]

New adaptive optics shows details of our star's atmosphere
Scientists from the U.S. NSF National Solar Observatory and New Jersey Institute of Technology produced the finest images in the Sun’s corona to date. Using a new 'coronal adaptive optics' system that removes blur caused by Earth's atmosphere, their ground-breaking results were recently published in Nature Astronomy…

UHZ1: NASA telescopes discover record-breaking black hole
This image contains the most distant black hole ever detected in X-rays , a result that may explain how some of the first supermassive black holes in the universe formed. As we report in our press release , this discovery was made using X-rays from NASA’s Chandra X-ray Observatory (purple) and infrared data from…

As cities grow in size, the poor 'get nothing at all': study
On average, people in larger cities are better off economically. But a new study published in the Royal Society Interface builds on previous research that says, that’s not necessarily true for the individual city-dweller. It turns out, bigger cities also produce more income inequality.

Biology Is Eating the World
We are at the beginning of a new era, where biology has shifted from an empirical science to an engineering discipline. After a millennia of using man-made approaches for controlling or manipulating biology, we have finally begun using nature’s own machinery—through biological engineering—to design, scale, and…
