An international team of archaeologists and scientists has reconstructed the diets of prehistoric communities from north-central Poland, shedding new light on how people adapted to changing environments and shifting social landscapes over three millennia between the Neolithic and the Bronze Age.

Is it a scratch behind the ears while staring into those puppy dog eyes, or is it a gentle pat on the back and a wagging tail that makes spending time with a therapy dog so comforting?

New research from UBC Okanagan suggests that when it comes to boosting wellbeing, it does not matter which part of a therapy dog students interact with—just that they do.

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.
