    Weekly: SpaceX makes history with Starship rocket; bringing thylacines back from extinction

    Episode 272 SpaceX has made history with its Starship rocket, the largest rocket ever built and one that’s hoped to eventually take us to Mars. In its fifth test, SpaceX successfully returned the rocket’s booster back to the launchpad and caught hold of it – an engineering feat of great finesse. But how close are we to putting crew on the rocket–- and when will it take humanity to the Red Planet? Leah-Nani Alconcel, spacecraft engineer at the University of Birmingham, joins the conversation. We might be closer than ever before to bringing Tasmanian tigers (thylacines) back from extinction. That’s if de-extinction company Colossal is right about their latest discovery, of a nearly complete genome of the thylacine. Is this the breakthrough it seems to be? And can we truly bring back thylacines as they once were?   Brain scans have revealed that bullying has a physical effect on the structure of the brain. Young people who are bullied see changes in various brain regions and it seems to impact male and female brains differently. Are these changes permanent? And is this cause to take bullying more seriously? The “very fabric of life on Earth is imperilled.” That’s according to the latest annual State of the Climate report. Thirty-five “planetary vital signs” have been assessed by researchers and the outlook is bleak. But among all the worrying climate records we’ve broken there is hope. Hear from study author Tom Crowther of ETH Zurich.  Hosts Rowan Hooper and Chelsea Whyte discuss with guests Leah Crane, Leah-Nani Alconcel, Michael Le Page, Alexandra Thompson, James Dinneen and Tom Crowther.

    Weekly: Climate overshoot - when we go past 1.5 degrees there is no going back

    Episode 271 If we overshoot 1.5 degrees of global warming, there is no going back. The hope has long been that if - and when - we blow past our climate goals, we can later reverse the damage. But there’s no guarantee we can bring temperatures back down, according to a paper published in Nature this week. The report suggests it would take decades to get back to normal - and some of the more devastating consequences will be irreversible. Hear from a variety of experts on the problem of climate overshoot. Living bacteria have been discovered in 2-billion-year-old rocks, making them very, very old. Find out how these primitive microbes survived for so long - and why this discovery is exciting news for the quest to find life on other planets. Do you think you’ll make it to the ripe old age of 100? Human life expectancy has steadily been going up and up - but now it’s grinding to a halt, looking unlikely to exceed 84 for men and 90 for women. What’s going on? Is there a limit to human ageing, or is something else at play? Hurricane Milton has caused immense damage across Florida and the death toll is rising. As it draws power from the hot oceans, there’s good reason to believe climate change is to blame for its rapid intensification. Hot on the heels of Hurricane Helene, why are extreme weather conditions picking up again so quickly? Hosts Rowan Hooper and Chelsea Whyte discuss with guests Michael Le Page, Carl-Friedrich Schleussner, Joeri Rogelj, Wim Carton, Sam Wong, Carissa Wong and James Dinneen.

    Weekly: Hope for the world’s coral; the first drone vs drone war

    Episode 270 There may be hope for the survival of coral reefs, a vital part of the global underwater ecosystem that is under massive threat from climate change. At 1.5 C degrees of warming we’re at risk of losing 70-90 per cent of coral - and more than 99 per cent is estimated to die off at 2 degrees. But new research suggests corals may be more adaptable and resilient than we thought. Hear from two experts on the matter, Chris Jury of the University of Hawaii and Terry Hughes, director of the Centre of Excellence for Coral Reef Studies at James Cook University in Australia. A new exoplanet has been discovered in orbit around Barnard’s star - Earth’s closest single stellar neighbour. But could it be home to extraterrestrial life? And in this, the golden age of exoplanet discovery, how close are we to finding one that looks like Earth? Remarkably preserved remains of a 16 month old toddler have been analysed, painting a detailed picture of life in ancient Italy. Despite being 17,000 years old, DNA samples have shown us the colour of the child’s skin, his eye colour, health conditions and even how closely his parents were related. Russia’s invasion of Ukraine has been dubbed the “first drone war”. As the war rages on, drone combat has shifted from ad hoc, random encounters to highly strategic and coordinated assaults. With the increasing capabilities of drones and a ramp up in the expertise of operators, is this the future of the war - and is it a good thing? Hosts Rowan Hooper and Chelsea Whyte discuss with guests Terry Hughes, Chris Jury, Alex Wilkins, Sam Wong and Jacob Aron.
