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).
Observations made with the Hubble Space Telescope show how our galaxy has grown over billions of years.
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.
Crave's Eric Mack recently trekked to the top of Hawaii's Mauna Kea volcano to visit one of the most advanced observatories on Earth, the "eyes of humanity" in the middle of the Pacific.
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.
Researchers say they have determined the precise chemical structure of the HIV capsid, a protein shell that protects HIV's genetic material and enables it to debilitate the immune system.
Scientists say their tech is inspired by the canine olfactory mucus layer, which absorbs and then concentrates airborne molecules.
