Technology and society: The “maker” movement could change how science is taught and boost innovation. It may even herald a new industrial revolution
Astronomers in Germany have developed an artificial intelligence algorithm to help them chart and explain the structure and dynamics of the universe around us with unprecedented accuracy. The team, led by Francisco Kitaura of the Leibniz Institute for Astrophysics in Potsdam, report their results in the journal Monthly Notices of the Royal Astronomical Society. Scientists…
Our first foray into laser-equipped combat aircraft was the Airborne Laser Testbed, a Boeing 747 with a gigantic chemically-pumped megawatt laser turret in its nose. It was pretty awesome from a conceptual standpoint, but it didn’t work very well, and was scrapped last year. This doesn’t mean that the idea of high-powered lasers on aircraft…
Spacefaring worms undergo genetic changes associated with longer lives in their Earth-bound cousins, research has shown. A number of Caenorhabditis elegans worms were carried aboard a mission to the International Space Station (ISS) and brought back for study. Researchers found reduced activity of five genes in the worms that, when suppressed in the species on…
Here’s an interesting idea. Moore’s Law states that the number of transistors on an integrated circuit doubles every two years or so. That has produced an exponential increase in the number of transistors on microchips and continues to do so. But if an observer today was to measure this rate of increase, it would be…
There was a time not that long ago when it was easy to tell the difference between viruses and the rest of life. Most obviously, viruses were tiny and genetically simple. The influenza virus, for example, measures about 100 nanometers across, and has just 13 genes. Those two standards, it’s now clear, belong in the…
Small increases in temperature may have reduced the industrial and agricultural production of poor countries, according to a study by U.S. economists. Higher temperatures may also have contributed to political instability in these countries — defined as those with below-median per capita income, adjusted for the purchasing power of the country’s currency — according to…
