New technique for sorting micro-particles uses sound waves

Thanks to the rapid progress in tiny tech, we've been mainly using microfluidics to sort tiny particles by size. But now, there's a new way to sort them by shape, which could be a big deal for medical tests and chemistry. ...

A molecular fingerprint beyond the Nyquist frequency

Ultrashort pulses play a significant role in spectroscopic applications. Their broad spectral bandwidth enables simultaneous characterization of the sample at various frequencies, eliminating the need for repeated measurements ...

Study predicts best times for Curiosity to sample Mars' methane

Since methane was first detected in Mars' atmosphere 20 years ago, scientists have struggled to uncover its origins and how it is transported around the Red Planet. Measurements from atmospheric samples collected by NASA's ...
