NASA's mission to search for signs of extraterrestrial life on Jupiter's moon Europa is discussed, highlighting the significance of this dedicated mission and its goal of reaching the moon's ice-covered surface to sample material for signs of life.

Scientists sequenced DNA in Neandertal dental plaque to learn about their diets and their relationship with modern humans. The study revealed differences in diet between northern and southern Neanderthals, their use of natural painkillers, and their mouth microbiome similarity to chimps.

Exploring doubts and issues with forensic evidence in courtrooms, the podcast questions the credibility of accepted science in the legal system.

Discover the potential for finding monster gravitational waves through Pulsar Timing Arrays, which could surpass the waves detected by LIGO and LISA.

This podcast discusses atmospheric rivers and their impact on extreme weather events. Atmospheric rivers can carry the same amount of water vapor as 15 to 20 Mississippi Rivers and deliver punishing winds. Research predicts a rise in frequency and intensity of atmospheric rivers due to global temperature increase.

The last holdout of woolly mammoths on Wrangel Island had harmful mutations, resulting in satiny coats and a weakened sense of smell. The survival of this small population raises questions about genetic mutations in rare animals today.

Learn how climate change and overfishing are harming African penguins, pushing them into food-poor habitats. Researchers are discussing solutions like translocating chicks and implementing sustainable fisheries regulations to save their declining populations.

Discover how Neandertal gene variants affect gene expression in modern humans, impacting protein production, activating other genes, and even reducing the risk of schizophrenia and increasing height.

The discussion dives into the complexities of studying medical marijuana due to its federal Schedule I status. Researchers are caught in a dilemma: they need more evidence of its medicinal benefits to change its classification, but the current status complicates large-scale studies. Potential solutions are explored to overcome these research barriers, and the implications for drug development are highlighted. It's a fascinating look at the intersection of science, regulation, and cannabis health benefits.

Red blood cells remember high-altitude exposure, enhancing acclimation. Memory fades in four months. Body adjusts to low oxygen levels by depleting E-ENT1, allowing for faster acclimatization during return visits.
