Scientists map changes in soot particles emitted from wildfires

Not many people would voluntarily fly through plumes of smoke emitted from wildfires. But atmospheric scientists from the U.S. Department of Energy's Brookhaven National Laboratory do, over and over, tracing flight paths ...

Understanding quantum mechanics with active particles

Physicists led by Prof Raphael Wittkowski and Prof Uwe Thiele from the Institute of Theoretical Physics at the University of Münster has developed a new model for the dynamics of systems consisting of many self-propelled ...

Theoretical study: Cooling particles with laser light fields

Using lasers to slow down atoms is a technique that has been used for a long time already: If one wants to achieve low-temperature world records in the range of absolute temperature zero, one resorts to laser cooling, in ...

How advanced optical tweezers revolutionized cell manipulation

Optical tweezers (OTs), also known as optical traps, are highly focused laser beams that can be used to trap and manipulate microscopic objects with a noncontact force. Employed in a wide range of nano and micro-scale operations, ...
