Roland Pease reports from the American Association for the Advancement of Science鈥檚 annual meeting in Seattle. At the UK Research and Innovation鈥檚 stand in the exhibition hall, he鈥檚 joined by three scientists to discuss monitoring the Coronavirus outbreak, the locusts devastating crops in East Africa and the ever increasing amount of space junk orbiting the Earth.

Professor Jeffrey Shaman of the Mailman School of Public Health at Columbia University talks about how he is modelling the movement of Covid-19 around China and beyond.

Dr Catherine Nakalembe, of the University of Maryland and East Africa Lead for NASA Harvest explains how she uses data collected by satellites to find out where crops are thriving and where they are not. She also talks about how this technology can alert countries to approaching locust swarms.

And Professor Moriba Jah of University of Texas at Austin, tells Roland why he鈥檚 concerned about the amount of space junk that鈥檚 orbiting the earth and why so little is being done about controlling satellite launch and disposal.
