	Description:		It’s been an unusual week for astronomers, with telescopes swivelled off course to observe GRB221009A, the brightest gamma ray burst ever recorded. Gamma ray bursts aren’t unusual, the by-product of some supernovae are recorded weekly. Whilst the afterglow of these bursts usually lasts hours or days, the aftermath of, what has been dubbed ‘BOAT’, brightest of all time, is expected to linger for years to come. Harvard University’s Edo Berger and Yvette Cendas believe there’s lots to be learnt in the coming months. Back in the primordial oceans, tiny, wriggling worms and shimmering jellyfish invented ever better ways to strip resources from their environment deep in the murky depths. The ability to efficiently take up oxygen from a marine environment acted as a gateway for a dramatic explosion in species diversity. But according to Michael Sackville, Postdoctoral Fellow University of Cambridge and Woods Hole Marine Biological Laboratory, when the gills first appeared they may have carried out a rather different function. Plastics litter our oceans, and after time return to the shores. In order to predict and better understand where these plastic hotspots are, Professor Bhavani Narayanaswamy, Benthic Ecologist for Scottish Association for Marine Science, travels all over the globe to gather data and model these plastic hotspots. In the future, this plastic waste could be broken down by a biological organisms. Chemical biologist Dr Federica Bertocchini at the University of Cantabria has identified enzymes responsible for munching through resilient polymers in waxworms.
