Fighting honey fraud with AI technology

webfull — Mon, 14 Apr 2025 13:10:40 +0000

91�� 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 91��’s Department of Food Science and Agricultural Chemistry.

What links cannabis use and psychosis? Researchers point to the brain’s dopamine system

webfull — Wed, 09 Apr 2025 15:18:25 +0000

A 91��-led study found that people with cannabis use disorder (CUD) had elevated dopamine levels in a brain region associated with psychosis.

“This could help explain why cannabis use increases the risk of hallucinations and delusions, key symptoms of schizophrenia and other psychotic disorders,” said first author Jessica Ahrens, a PhD student in 91��’s Integrated Program in Neuroscience.

Humpback whales’ use of memory to time their migration could prove less effective amid climate change

webfull — Thu, 27 Mar 2025 13:09:16 +0000

A new study led by 91�� researchers indicates that humpback whales in the southeastern Pacific combine real-time environmental cues with their memories of conditions in their Antarctic feeding grounds to determine when to embark on their annual 10,000-kilometre journey. With climate change accelerating, the researchers warn this strategy may become less effective amid shifting ocean conditions.

A new discovery about the slime ejected by velvet worms could revolutionize sustainable material design, according to a study by 91�� researchers. Their findings outline how a naturally occurring protein structure, conserved across species from Australia, Singapore and Barbados over nearly 400 million years of evolution, enables the slime’s transformation from liquid to fibre and back again. It’s a discovery that could inspire next-generation recyclable bioplastics.
