Ketchup is an essential companion of American summer cuisine, but where did it come from?
New tools—and math—are shifting our picture of a vital reproductive cell.
Astronauts just bioengineered human cells on the International Space Station.
As the U.S., Russia, and other nations push forward on COVID-19 vaccine trials, what happens to countries that can’t develop their own?
For months, the incarcerated population has been battling COVID-19—and the struggle to contain the disease is highlighting systemic public health issues.

On Episode 155, Trevor Graff and Adam Naids, Project Manager for exploration science and Deputy Project Manager for Artemis geology tools, respectively, share their expertise on the tools needed for the Moon’s unique terrain when we visit our neighboring satellite during Artemis missions.
Speciation is often considered unidirectional: a continual process of divergence interrupted only by extinction events. However, this isn’t entirely true. In this episode Dr Jente Ottenburghs (Wageningen University) discusses the curious case of the bean geese: where speciation appears to have stopped and, perhaps, begun to reverse.

The antagonistic co-evolution that characterises host-parasite relationships is one of the most fascinating interactions in genetics. In this episode, Dr Gilberto Bento discusses one such interaction, the Daphnia–Pasteuria host–parasite system, and the discovery of an alternative route of bacterial infection associated with a novel resistance locus. Dr Bento also talks about his experience of leaving academia to find an alternative career in science.

In episode five of our editorial series we meet Dr Rui Faria from the Research Center in Biodiversity and Genetic Resources at the University of Porto (Portugal). Dr Faria’s research looks at the role of chromosomal inversions in the generation of biological diversity, focusing on Littorina snails as a model. And, in a more personal inversion, Dr Faria took his first steps behind a scientific journal when he joined the Heredity Editorial team in May 2019: tune in to discover how he made the leap and what he thinks makes a great paper submission.
The arms race between the highly toxic rough-skinned newts of North America and the garter snakes that prey upon them is a literal textbook example of evolution in action. However, it appears that a piece of the genetic puzzle underpinning this interaction has been overlooked, until now. In this episode, PhD candidate Kerry Gendreau (Virginia Tech) and Dr Michael Hague (University of Montana) discuss their recent work showing that toxin resistance in garter snakes is sex-linked, and the implications this has for a system that is taught to almost every biology student.

Hear how the Kennedy Space Center Launch team has persevered through a global pandemic to get a Mars Rover named Perseverance to the pad on time.
Does dark matter interact with black holes? What’s the best alien in film? Is the universe infinite? On this episode, Neil deGrasse Tyson and comic co-host Chuck Nice answer a cosmic cauldron of fan-submitted Cosmic Queries.

For Episode 154, Richard Danne, designer and creator of NASA’s “worm”, details the origins of the iconic logo, the inspiration, the design process with the agency and his firm, Danne and Blackburn, and its reception once being introduced. Retired in 1992, NASA reinstated the “worm” in May 2020 during the SpaceX Demo-2 mission.
We’re going to Mars! NASA’s Perseverance rover will head to Mars this summer to search for signs of ancient life. Christina Hernandez and Mitch Schulte tell us all about Mars Perseverance in this special edition episode of NASA’s Curious Universe.
Scientists say phenomena on the surface of the Sun look like “campfires.”
