This month, Brazil has seen some of its highest recorded temperatures. The country’s Pantanal wetlands, the largest tropical wetlands in the world, have been scorched by wildfires. The region is home to vibrant wildlife, including jaguars, anacondas and various birds. Professor Letícia Couto Garcia, leader of the Intervention Ecology Lab at Mato Grosso Federal University in the South, Brazil, talks about some of the challenges she’s experienced. Staying with extreme temperatures, Dr Robert Rohde of the independent non-profit, Berkeley Earth, reveals what the recently recorded excess of 2°C means. This week, we learned that an extremely energetic particle had been detected. Dr Toshihiro Fujii of Osaka Municipal University tells us how he first made the discovery after trawling through some data. We then hear from Dr Yvette Cendes, an astronomer who specialises in high-energy physics, to find out more about the origins of this particle.Finally, Science in Action visits the South African Astronomical Observatory, to learn about the projects that could bring more diverse voices to our understanding of the night sky.
