Using a precisely aligned pair of laser beams, scientists can now hold a single aerosol particle in place and monitor how it charges up. The particle’s glow signals each step in its changing ...

Like bakers measuring the exact same amount of flour every time they made bread, physicists at The University of Texas at Austin have used a laser trap to consistently capture and measure the same ...

With the innovative new optical tweezers developed by the Freiburg researchers, a quickly moving, focused laser beam holds a tiny, spiral-shaped bacterium in place and records its movements in detail.

Since the first laser was invented in 1960, they've always given off heat—either as a useful tool, a byproduct or a fictional way to vanquish intergalactic enemies. But those concentrated beams of ...

UK scientists have used a laser beam trap to examine how drug particles from asthma inhalers behave as they are projected through the air. Their findings could improve the effectiveness of inhalers ...

What initiates the first spark of lightning has long been the core mystery of a thunderstorm. Now, a new experiment at the Institute of Science and Technology Austria (ISTA) is shedding light on the ...

Scientists in the UK have combined two different optical techniques to test the effectiveness of asthma inhalers in a completely new way. Using a laser beam trap to levitate tiny particles containing ...

Got a bit of a pest problem? [Chad] built a better squirrel/rabbit/thing trap using a soekris box, a laser pointer, serial controlled relay and a small motor. When the laser beam is broken, the ...
