An international team of researchers has proposed and demonstrated an efficient approach for triggering, trapping and guiding electrical discharges in air. Their technology is based on the use of a low-power laser beam that traps and transports light-absorbing particles in mid-air. Experimental configuration and principles of optical vortex beam for …

Many of us have downloaded cracked software from the darker corners of the internet over the years. Remember when the only way to get Photoshop was to buy a $700 license? Yeah, enough said. Some of the most prolific users of cracked software these days aren’t who you think. Farmers …

Physicists in Germany have developed a novel technique for trapping biological cells with a laser beam. Using this technique, the researchers obtained super-resolution images of chromosomal DNA within E. coli cells. Picture of the distribution of the genetic information in an E. coli cell.

One of the problems with imaging living biological cells is that they don’t want to be held still. Or, more accurately, they don’t want to be held to a surface like a microscope slide. Prepping and fixing the cells changes them irrevocably, altering whatever a scientist was trying to observe. …
