A powerful earthquake hit Taiwan on Wednesday morning, but thanks to the country’s early warning system and engineering-preparedness, there was little destruction and few deaths. Seismologist Ross Stein, CEO of earthquake consultancy Temblor, Inc., shares his analysis. The highly pathogenic bird flu H5N1 has been detected in cattle in the US and in a cattle handler in Texas. To learn more about this special animal-to-human transmission, Roland speaks to virologist Richard Webby of St. Jude Children’s Research Hospital in Tennessee and Director of the World Health Organization Collaborating Center for Studies on the Ecology of Influenza in Animals. French Space Institute Supaero in Toulouse is collaborating with Japan’s space agency JAXA to send and land a rover on Phobos, one of Mars’ tiny moons. Roland travels to the University of Toulouse to learn more about building this wheeled Rover from Supaero’s Naomi Murdoch. Transitioning to a clean energy future requires mining materials like rare earth minerals, but how will this impact our environment? Jessi Junker of the ecology charity ReWild explains her research and concerns for great apes as mining for these materials expands in Africa.
