Science In Action Folgen

An outbreak of pathogenic bird flu, H5N1, in a Spanish mink farm could be a cause for concern. Some experts fear the virus may now spill over to other mammals without strict surveillance. Marion Koopmans, professor of virology at Erasmus Medical Centre, talks Roland through the potential risks. India’s caste system affects all aspects of society, but how does the hierarchy influence representation of marginalised groups in academia? Science journalist Ankur Paliwal believes that, despite efforts to combat discrimination, not enough is being done, and he has the data to prove it. Imagine a robot... Is it hard, metallic and humanoid? Professor Carmel Majidi from Carnegie Mellon University and his colleagues are thinking outside the robotics box. Their new material, magnetic in nature, can shift between solid and liquid states. It’s even capable of breaking out of robotic jail... And how do echidnas – spiny, long-nosed, egg-laying mammals – manage to stay cool during the hot Australian summers?

Climate researcher, Rose Abramoff took to the stage at the American Geophysical Union (AGU) fall meetings, not as a guest speaker but in protest. Whilst her demonstration only lasted 15 seconds, she found her employment terminated from Oak Ridge National Laboratory and research stripped from the AGU programme. She was attempting to persuade other climate scientists to ‘get out of the lab and into the street’. Whilst Rose’s protest hit the headlines in the media, potentially less attention was paid to the session that was taking place at the conference, hosted by Mika Tosca, climate scientist-turn-artist, Associate Professor of Liberal Arts at the School of the Art Institute of Chicago. Roland brings the two together to discuss the event and how climate scientists should approach activism. Although there is no one solution to the climate crisis, Roland loves a brainstorm on Science in Action. Climate activist Stuart Capstick, a Cardiff University psychologist specialising in public attitudes to environmental issues and environmental scientist Robert Young from Western Carolina University take the conversation one step further. Questioning how public perceptions of scientists change when they take evasive action and protest.And finally, we usually hear of seismology reports coming from dense, urban areas prone to earthquakes, delicately perched atop of tectonic plates. But this week, Roland speaks to Professor of Geophysics Zhongwen Zhan from the California Institute of Technology, who’s collecting data from a very unusual place...

Flood warnings in parts of California have seen some of the state’s best known celebrities flee their homes. The current weather conditions are in part the result of ‘Atmospheric rivers’ – literally fast flowing rivers of water vapor in the atmosphere. Marty Ralph from the Scripps Institute has been studying this phenomenon for years, he explains what atmospheric rivers are, and tells us how a greater understanding of the phenomenon is now informing weather forecasting and evacuation plans.Over the past year several million people have fled Ukraine, amongst them many scientists. Nataliya Shulga from the Ukraine Science Club is working on a wide ranging initiative to attract them back. She tells us of plans not just to reconstruct Ukrainian science facilities after the war, but to offer a philosophical change which breaks with the Soviet past - a more global, collaborative environment for scientists returning to the Ukraine. Last December the Afghan Taliban banned women from attending university, its just one of the many moves denying education to women since the Taliban returned to power. Particle physicist Kate Shaw had been working with Afghan physicists in the years before the Taliban’s comeback, she is now developing an initiative with scientists and institutions around the world to offer places to Afghan women keen to study physics. She says institutions and individuals who may be able to help should contact Physics without Frontiers at the International Centre for Theoretical Physics. And Gibbons sing with synchronicity, a new study led by Teresa Raimondi, from the University of Turin shows the ability of couples to chorus together to be rather human like.Image Credit: Josh EdelsonPresenter: Roland Pease Producer: Julian Siddle
