Exploring the properties of a vanishingly-rare artificial element, and the AI that generates new mathematical conjectures.In this episode:01:04 Einsteinium's secretsEinsteinium is an incredibly scarce, artificial element that decays so quickly that researchers don’t know much about it. Now, using state-of-the-art technology, a team has examined how it interacts with other atoms, which they hope will shed new light on einsteinium and its neighbours on the periodic table.Research Article: Carter et al.06:28 Research HighlightsThe mysterious appearance of three ozone-depleting chemicals in Earth’s atmosphere, and how ride-sharing services have failed to reduce traffic jams.Research Highlight: Mystery on high: an ozone-destroying chemical appears in the airResearch Highlight: Uber and Lyft drive US gridlock — but not cuts in car ownership8:38 The computer that comes up with new mathematical formulasA team of researchers have developed artificial-intelligence algorithms that can generate new formulas for calculating the digits of key mathematical numbers like pi. Although crucial, many of these numbers remain mysterious, so it is hoped that this system will open up new avenues of questioning for mathematicians.Research Article: Raayoni et al.14:48 Briefing ChatWe discuss some highlights from the Nature Briefing.

A year ago the WHO’s coronavirus emergency alarm was largely ignored. Why?On 30 January 2020, the World Health Organization (WHO) declared a ‘public health emergency of international concern’, or PHEIC, to raise the alarm of the imminent threat of a global coronavirus pandemic.Alongside the PHEIC, the WHO made a number of recommendations to curb the spread of the virus. But many of these were ignored by governments around the world.In this episode of Coronapod, we explore why this emergency warning system failed, and hear about efforts to reform it, and the WHO, to avoid this happening again.News: Why did the world’s pandemic warning system fail when COVID hit?

Researchers are probing the subtle physical forces that sculpt cells and bodies.At every stage of life, from embryo to adulthood, physical forces tug and squeeze at bodies from within.These forces are vital, ensuring that cells are correctly positioned in a developing embryo, for example. But they also play a role in diseases like cancer. Yet despite their importance, relatively little is known about how cells sense, respond to and generate these forces.To find out, researchers have turned to bespoke tools and methods, using them to probe lab-cultured cells and whole animals to get to the root of how mechanical forces sculpt life.This is an audio version of our feature: The secret forces that squeeze and pull life into shape Hosted on Acast.

A neuroprosthetic device restores blood-pressure control after spinal-cord injury, and identifying the neurons that help us understand others’ beliefs.In this episode:00:47 A neuroprosthetic restores the body’s baroreflexA common problem for people who have experienced spinal-cord injury is the inability to maintain their blood pressure, which can have serious, long-term health consequences. Now, however, researchers have developed a device that may restore this ability, by stimulating the neural circuits involved in the so-called baroreflex.Research Article: Squair et al.News and Views: Neuroprosthetic device maintains blood pressure after spinal cord injury08:27 Research HighlightsHow gesticulating changes the way that speech is perceived, and a new theory of how Saturn got its tilt.Research Highlight: Hands speak: how casual gestures shape what we hearResearch Highlight: The moon that made Saturn a pushover10:58 A neuronal map of understanding othersHumans are very good at understanding that other people have thoughts, feelings and beliefs that are different to our own.
