Measles is a dangerous infection that can kill. As many as 100,000 people die from the disease each year. For those who survive infection, the virus leaves a lasting mark—it appears to wipe out the immune system’s memory. News Intern Eva Fredrick joins host Sarah Crespi to talk about a pair of studies that looked at how this happens in children’s immune systems. Read the related studies in Science and Science Immunology. In our second segment this week, Sarah talks with Todd Thompson, of Ohio

Earthworms are easy … to find. But despite their prevalence and importance to ecosystems around the world, there hasn’t been a comprehensive survey of earthworm diversity or population size. This week in Science, Helen Philips, a postdoctoral fellow at the German Centre for Integrative Biodiversity Research and the Institute of Biology at Leipzig University, and colleagues published the results of their worldwide earthworm study, composed of data sets from many worm researchers around the globe

We don’t know where consciousness comes from. And we don’t know whether animals have it, or whether we can detect it in patients in comas. Do neuroscientists even know where to look? A new competition aims to narrow down the bewildering number of theories of consciousness and get closer to finding its biological signs by pitting different theories against each other in experimental settings. Freelance journalist Sara Reardon talks with host Sarah Crespi about how the competition will work. In our

Have you ever tried to scrub off the dark, tarlike residue on a grill? That tough stuff is made up of polymers—basically just byproducts of cooking—and it is so persistent that researchers have found similar molecules that have survived hundreds of millions of years. And these aren’t from cook fires. They are actually the byproducts of death and fossilization. Host Sarah Crespi talks with Contributing Correspondent Gretchen Vogel about how these molecules can be found on the surface of certain

(Read the related research article in Science Advances.) And I talk with Kenneth Rosenberg, an applied conservation scientist at Cornell University, about steep declines in bird abundance in the United States and Canada.

In La Rinconada, Peru, a town 5100 meters up in the Peruvian Andes, residents get by breathing air with 50% less oxygen than at sea level. International News Editor Martin Enserink visited the site with researchers studying chronic mountain sickness—when the body makes excess red blood cells in an effort to cope with oxygen deprivation—in these extreme conditions. Martin talks with host Sarah Crespi about how understanding why this illness occurs in some people and not others could help the

Micro-organisms live inside everything from the human gut to coral—but where do they come from? Host Meagan Cantwell talks to Staff Writer Elizabeth Pennisi about the first comprehensive survey of microbes in Hawaii’s Waimea Valley, which revealed that plants and animals get their unique microbiomes from organisms below them in the food chain or the wider environment. Going global, Meagan then speaks with Erle Ellis, professor of geography and environmental science at the University of Maryland,

Imagine having a rat clinging to your back, sucking out your fat stores. That’s similar to what infested bees endure when the Varroa destructor mite comes calling. Some bees fight back, wiggling, scratching, and biting until the mites depart for friendlier backs. Now, researchers, professional beekeepers, and hobbyists are working on ways to breed into bees these mite-defeating behaviors to rid them of these damaging pests.

Can we inherit trauma from our ancestors? Studies of behavior and biomarkers have suggested the stress of harsh conditions or family separations can be passed down, even beyond one’s children. Journalist Andrew Curry joins host Sarah Crespi to discuss a possible mechanism for this mode of inheritance and mouse studies that suggest possible ways to reverse the effects.

Researchers have been making animal embryos from two different species, so-called “chimeras,” for years, by introducing stem cells from one species into a very early embryo of another species. The ultimate goal is to coax the foreign cells into forming an organ for transplantation. But questions abound: Can evolutionarily distant animals, like pigs and humans, be mixed together to produce such organs? Or could species closely related to us, like chimps and macaques, stand in for tests with human
