In AIP Advances, researchers develop a way to remotely fingerprint and identify a cellular device. Using specialized SIM cards and cellular radio standards-compliant base station emulator equipment, the researchers commanded a set of “trusted” cell phones to transmit the exact same sets of signals, allowing them to create a database of what these signals really look like for different phone models. By comparing the signals emitted by an unknown device to the database, the researchers can figure out if the device has been altered.
An international research team has used ancient DNA to uncover a 7,700-year-old "north-south corridor" connecting Siberia's Lake Baikal region with northern China. By analyzing 42 ancient genomes, the study, published in Science Bulletin, challenges the view that major trans-Eurasian contact only began in the Bronze Age. The findings link Early Neolithic groups genetically (via Ancient Paleo-Siberian ancestry) and archaeologically (via similar pottery and burial posture).
