Seasteading: Libertarians dream of creating self-ruling floating cities. But can the many obstacles, not least the engineering ones, be overcome?
Andy Murray’s unexpectedly strong start against Roger Federer in the Wimbledon 2012 final put the Daily Telegraph columnist Matthew Norman in a science-fiction mood. ‘It seemed we’d been transported to one of those parallel universes into which Doctor Who likes to slip with insouciant ease,’ he commented. A year later, that alternative world became reality,…
In a vacuum, light travels so fast that it would circle Earth more than seven times within the blink of an eye. When light propagates through matter, however, it slows by a factor typically less than 5. This factor, called the refractive index, is positive in naturally occurring materials, and it causes light to bend…
Rocks, water and hot alkaline fluid rich in hydrogen gas spewing out of deep-sea vents: this recipe for life has been championed for years by a small group of scientists. Now two of them have fleshed out the detail on how the first cells might have evolved in these vents, and escaped their deep sea…
If you have an iPad, you can take a closer look at one of history’s greatest minds. The National Museum of Health & Medicine, Chicago released an app that displays slides of Albert Einstein’s brain. The app is for sale to researchers and curious iPad users alike, and all profits are going to the Chicago…
Though life is a complicated brew, some of its ingredients can be plucked from Earth’s backyard instead of being imported from more distant interstellar fields. In a new study, scientists suggest that complex organic molecules — such as the amino acids that build proteins and the ringed bases that form nucleic acids — grow on…
Scientists have taken a first early step toward escaping the limits of a technological principle called Moore’s Law by creating a working transistor using a single phosphorus atom. The atom was etched into a silicon bed with “gates” to control electrical flow and metallic contacts to apply voltage, researchers reported in the journal Nature Nanotechnology….
