Ultrashort laser pulses can be used to generate X-rays. Normally, however, only certain specific frequencies are produced. A team from TU Wien and the University of California San Diego has developed a method that makes it possible to tune the frequency continuously.

Scientists have found evidence that black holes of vastly different sizes may launch powerful jets according to the same universal rule. Supermassive black holes can produce jets soon after tearing apart a star, then fire up again hundreds or thousands of days later when their feeding rate drops...
Flies, mice and humans move in different ways because of their very different physiques, but their movements follow a common pattern— joints farther from the center of the body move faster than those closer to the body. This was demonstrated in a study conducted by a research team from the Unive...
