X-rays, Bond Breaks, and Climate…
An X-ray flash illuminates a molecule. Credit: Raphael Jay Topics: Chemistry, Climate Change, Green Tech, High Energy Physics, Research, X-rays The use of short flashes of X-ray light brings scientists one big step closer to developing better catalysts to transform the greenhouse gas methane into a less harmful chemical. The result, published in the journal Science,…

Source: Washington Monthly, “The 12 Early Warning Signs of Fascism,” Martin Longman, January 31, 2017 Topics: Civics, Civil Rights, Civilization, Democracy, Existentialism, Fascism, Human Rights But beyond him being (obviously) a genocidal maniac, there’s an aspect to Hitler’s rule that kind of gets missed in our standard view of him. Even if popular culture has…

Schematic diagram of the worm-inspired robot. Credit: Jin et al. Topics: Applied Physics, Biomimetics, Instrumentation, Mechanical Engineering, Robotics Bio-inspired robots, robotic systems that emulate the appearance, movements, and/or functions of specific biological systems, could help to tackle real-world problems more efficiently and reliably. Over the past two decades, roboticists have introduced a growing number of…

This map predicts how air pollution with fine particles will be in the future – according to Ulas Im’s computer simulation. The blue-colored areas show where the pollution is worst. Green is a little better, and yellow means almost no pollution. Credit: Journal for Environmental Research Topics: Civilization, Environment, Existentialism For many years now, we have…

The disinfectant powder is stirred in bacteria-contaminated water (upper left). The mixture is exposed to sunlight, which rapidly kills all the bacteria (upper right). A magnet collects the metallic powder after disinfection (lower right). The powder is then reloaded into another beaker of contaminated water, and the disinfection process is repeated (lower left).
