Process for the optical analysis of trace gases optimized

Laser-based absorption spectroscopy is an important method for determining the concentration of gas components in a sample. Modern devices are highly specialized for detecting very specific gases, such as trace gases in the ...

Exploring how antibiotic-resistant bacteria become aggressive

Some strains of antibiotic-resistant bacteria that have recently acquired disease-enhancing genes may not behave as aggressively as expected, according to a Northwestern Medicine study recently published in Nature Communications.

Scientists measure the distance to stars by their music

A team of astronomers has used asteroseismology, or the study of stellar oscillations, to accurately measure the distance of stars from the Earth. Their research examined thousands of stars and checked the measurements taken ...
