Cities occupy just a small fraction of Earth's land, but they act as the planet's massive carbon engines, pumping out the lion's share of global CO₂ emissions. To stop climate change, we first have to measure it accurately—street by street and chimney by chimney. A comprehensive new review published in Carbon Research takes a deep dive into the sophisticated networks designed to "sniff out" these emissions, highlighting both the technological triumphs and the massive gaps still remaining in our global monitoring net.

The Ottawa Medical Artificial Intelligence Research Institute (OMARI) will empower responsible medical AI advances to strengthen healthcare systems and improve patient care; OMARI will raise awareness about the power of commercialization and next-gen innovation.

Achieving precise and predictable motion remains a persistent challenge for microelectromechanical systems (MEMS), where many actuators respond nonlinearly to electrical input. 

Winemakers have only a short window to pick their grapes to make the best quality wine. Everything from weather to soil acidity affect which date is best to harvest.

Prof Lei Su and Dr Xuechun Wang have invented a portable optical sensor which uses machine learning to give winemakers instant, accurate ripeness data, removing the need for manual sampling and slow destructive testing.

The team are looking for innovative vineyards, agritech partners, and fruit orchards to help test the prototype and shape the future of smart harvesting.
