Sandia collaboration produces improved microneedle technology
March 18, 2024 • ALBUQUERQUE, N.M. — Microneedles measure only two to three times the diameter of human hair and about a millimeter long. But their impact is significant, from helping U.S. service members in the field diagnose infections earlier, to helping individuals monitor their own health. Sandia National Laboratories is at the forefront...

Wearable sensor to monitor ‘last line of defense’ antibiotic
October 3, 2023 • ALBUQUERQUE, N.M. — Since the discovery of penicillin in 1928, bacteria have evolved numerous ways to evade or outright ignore the effects of antibiotics. Thankfully, healthcare providers have an arsenal of infrequently used antibiotics that are still effective against otherwise resistant strains of bacteria. Researchers at Sandia National Laboratories have...

Super plants need super ROOTS
February 28, 2017 • ALBUQUERQUE, N.M. — Agriculture consumes about 80 percent of all U.S. water. Making fertilizers uses 1 to 2 percent of all the world’s energy each year. A new program hopes to develop better crops — super plants that are drought-resistant, use less fertilizer and remove more carbon dioxide from the...
