Noninvasive inspection of layered structures is challenging for time-resolved imaging methods, where the resolution and contrast can be compromised by prominent signal attenuation with interlayer reflections and dispersions.
Canadian astronomers have identified mode changing and giant pulses in the millisecond pulsar known as PSR B1957+20. It is the first time when mode changing mechanism has been observed in a millisecond pulsar. The finding ...
In a laboratory at the University of Rochester, researchers are using lasers to change the surface of metals in incredible ways, such as making them super water-repellent without the use of special coatings, paints, or solvents.
