Microfabrication is—simply put—the construction of tiny things, including microscopic and nanoscopic objects and patterns. Microfabrication has major potential in medicine and biomedical engineering, in addition to fields like electronics and photonics—but first, researchers need to develop techniques that are biologically compatible. One team of researchers thinks a crucial step toward that goal involves tattooing tardigrades. […]
Lasers Expose Stunning Tattoo Art on 1,200-Year-Old Peruvian Mummies
If tattoos are prone to fading within a single human lifetime, imagine the wear-and-tear on the tattoos of 1,200-year-old mummies. An international team of researchers has, for the first time, used lasers to reveal tattoos on mummies from Peru. Using this technique, detailed in a January 13 study published in the journal PNAS, researchers uncovered […]
