Researchers have developed a new way to identify gases at very low concentrations in just seconds. The technique could allow for highly sensitive, real-time sensors for applications in environmental monitoring and medical breath analysis. The approach, called coherently controlled quartz-enhanced photoacoustic spectroscopy, can capture a complete methane spectrum in just 3 seconds where existing methods […]

A 3,000-year-old “mega fortress” in the Caucasus mountains has been mapped using drones, revealing the Bronze Age structure to be 40 times larger than previously thought. The fortress, named Dmanisis Gora, is about 65km southwest of Tbilisi, capital of Georgia. Dmanisis Gora was built between 1500–500 BCE. At the time, other massive fortresses were being […]
