Purdue University has helped develop a handheld sniffing system that can detect bacteria, drugs or any other residue of interest. Applications range from food safety to homeland security. In this video provided by Purdue, analytical chemist Graham Cooks explains DESI (Desorption Electrospray Ionization).
Yet another alleged "miracle" product has hit Kickstarter, but we're still some time away from a handheld food-analysing spectrometer.
Identifying distant planets that might be able to support life turns out not to be as straightforward as we might think, new research finds.
Observations made with the Hubble Space Telescope show how our galaxy has grown over billions of years.
Some suns gobble up the planets revolving around them, creating unique chemical signatures that could help astronomers in their planetary hunt.
Researchers in Vienna have developed a technique to quickly distinguish between strains of staph infection bacteria that can cause chronic infections and those that cannot.
Diabetes patients could one day check their glucose levels simply by shining a light into their skin.
A breakthrough laser technology can discriminate between cancerous prostate cells and healthy bodily fluids, and ultimately help predict when cancer will metastasize.
A study by researchers at the University of British Columbia indicates that a wireless near-infrared device the size of a cell phone is as reliable as current invasive tests in diagnosing bladder disease.
The mission's Chemistry and Camera instrument, or ChemCam, hit a fist-size rock with 30 pulses of its laser during a 10-second period. Each pulse delivers more than a million watts of power for about five one-billionths of a second.
