	Description:		In September 2012 Arctic sea ice melted to its minimum ever recorded and the German research ice breaker, Polarstern, ventured deep into the region North of Russia to record findings. It’s now retracing its steps, over a decade later, to observe how things have progressed. Autun Purser and Antje Boethius describe the journey and the importance of documenting developments in the face of climate change. Some 75 million individuals are believed to live with Long Covid and, in order to treat the plethora of symptoms presented by patients, researchers continue to search for the root source of the condition in the hope of better prescribing broad therapeutics. Akiko Iwasaki, Professor of Immunobiology at Yale University, updates Roland on the working hypotheses. And one year on from the Hunga Tonga eruption, where a shockwave circled the globe four times, researchers have been able to calculate the speed of the currents in the southern Pacific Ocean. BBC correspondent Jon Amos caught up with Michael Clare to hear how other South Pacific Islands can learn from the most explosive volcanic eruption in 100 years.
