The outbreak of bird flu currently tearing through the nation’s poultry is the worst in U.S. history. Scientists say it is now spreading beyond farms into places and species it has never been before.

Emily Anthes, a science reporter for The Times, explains.

39:T500,Sea ice coverage hit a recording-breaking low in the Antarctic this week, but what does this mean for the rest of the world? Why is the region so difficult to predict? And what could further changes in climate mean for the South Pole? Often the Arctic dominates conversations around polar warming but this week, with the help of climate modelling expert Tamsin Edwards, Kings College London, we’ll be tackling these questions and more. We’ll hear from British Antarctic Survey researcher Nadia Frontier, a marine biologist spending the summer at Rothera research base in the Antarctic. We join her as she traverses snow and ice to study the inhabitants of Adelaide island and the surrounding waters. Rachel Tilling from the Cryospheric Sciences Lab at NASA’s Goddard Space Flight Center helps us explore the continent from a different vantage point, explaining her work using satellite data to understand sea ice thickness. And climate reporter Georgina Rannard takes us through an artistic interpretation of polar sounds, Dr Geraint Rhys Whittaker uses underwater microphones to capture the impact of human activity on polar wildlife. Presenter: Victoria Gill Producers: Julian Siddle and Emily Bird BBC Inside Science is produced in collaboration with The Open University.3a:T445,Global sea levels are rising more than 3mm per year under current climate conditions. At this rate we are due to hit an alarming 7mm rise per year by the end of the century. If this is not slowed, it could lead to the drowning of essential coastal ecosystems like mangroves and lagoons, professor of environmental science Neil Saintilan tells Science in Action. The seas are also heating up. We’ve covered the devastating effect of marine heatwaves on vibrant sea life like coral reefs before. But what about the less glamourous bottom-dwelling fish? Ecologist Alexa Fredston has found that they may be more robust than we think. Also this week, bird virus expert Michelle Wille tells us about the imminent threat of bird flu spreading from South America to Antarctica where hundreds of thousands of sea birds are at risk. And from one south pole to another, we have an update on how India’s mission on the lunar south pole is going with Lunar and Planetary Institute scientist David Kring.
