Wealth inequality began shaping human societies more than 10,000 years ago, long before the rise of ancient empires or the invention of writing. That’s according to a new study led by Washington State University archaeologist Tim Kohler that challenges traditional views that disparities in wealth emerged suddenly with large civilizations like Egypt or Mesopotamia. The research is part of a special issue of the Proceedings of the National Academy of Sciences, co-edited by Kohler and Amy Bogaard, an archaeologist at Oxford University in England.

McGill University researchers have developed an AI-powered method to verify the origin of honey, ensuring that what’s on the label matches what’s in the jar. The breakthrough offers a potential solution to a long-standing problem.

“Honey is one of the most fraud-prone commodities in global trade. It often involves mislabelling where it was produced or the types of flowers that bees collected nectar from,” said lead author Stéphane Bayen, Associate Professor and Chair of McGill’s Department of Food Science and Agricultural Chemistry.
