Daily news stories

Should we bring animals back from extinction, three-parent baby announced, and the roots of human violence, with David Grimm.

 

From the magazine

Our networked world gives us an unprecedented ability to monitor and respond to global happenings. Databases monitoring news stories can provide real-time information about events all over the world -- like conflicts or protests. However, the databases that now exist aren’t up to the task. Alexa Billow talks with Ryan Kennedy about his policy forum that addresses problems with global data collection and interpretation.

Daily news stories

A quick change in chickens’ genes due to a papal ban on eating four-legged animals, the appeal of tragedy, and genetic defects in the “sixth sense,” with David Grimm.

 

From the magazine

In February of this year, one of the most regular phenomena in the atmosphere skipped a cycle. Every 22 to 36 months, descending eastward and westward wind jets—high above the equator—switch places. The Quasi-Biennial Oscillation, or QBO, is normally so regular you can almost set your watch by it, but not this year. Scott Osprey discusses the implications for this change with Alexa Billow.

News stories on our earliest hunting companions, should we seed exoplanets with life, and finding space storm hot spots with David Grimm.

 From the magazine

Two years ago, 43 students disappeared from a teacher’s college in Guerrero, Mexico. Months of protests and investigation have not yielded a believable account of what happened to them. The government of Mexico claims that the students were killed by cartel members and burned on an outdoor pyre in a dump outside Cucola. Lizzie Wade has been following this story with a focus on the science of fire investigation. She talks about an investigator in Australia that has burned pig carcasses in an effort to understand these events in Mexico.

News stories on magnetic waste in the brain, the top deal breakers in online dating, and wolves that are willing to “risk it for the biscuit,” with David Grimm.

 

From the magazine

How do we track where we are going and where we have been? Do you pay attention to your path? Look for landmarks? Leave a scent trail? The problem of navigation has been solved a number of different ways by animals. The desert-dwelling Cataglyphis ant was thought to rely on stride integration, basically counting their steps. But it turns out they have a separate method of keeping track of their whereabouts called “optic flow.” Matthias Wittlinger joins Sarah Crespi to talk about his work with these amazing creatures.

Over the last year and a half, scientists have studied the mysterious dwarf planet using data collected by Dawn, including detailed images of its surface. Julia Rosen talks with Debra Buczkowski about Ceres’s close-up.

From the magazine

This story combines two things we seem to talk about a lot on the podcast: reproducibility and the microbiome. The big question we’re going to take on is how reproducible are mouse studies when their microbiomes aren’t taken into account? Staff writer Kelly Servick is here to talk about what promises to be a long battle with mouse-dwelling bugs.

News stories on using pets in clinical trials to test veterinarian drugs, debunking the Piltdown Man once and for all, and deciding just how smart crows can be, with David Grimm.

 

From the magazine

It’s really difficult to figure out how old a free-living animal is. Maybe you can find growth rings in bone or other calcified body parts, but in sharks like the Greenland shark, no such hardened parts exist. Using two different radiocarbon dating approaches, Julius Neilsen and colleagues discovered that the giant Greenland shark may live as long as 400 years.

 From the magazine

Rivers deliver water to the ocean but water is also discharged along the coast in a much more diffuse way. This “submarine groundwater discharge” carries dissolved chemicals out to sea. But the underground nature of these outflows makes them difficult to quantify.  Audrey Sawyer talks with Sarah Crespi about the scale of this discharge and how it affects coastal waters surrounding the United States.

Stories on birds that guide people to honey, genes left over from the last universal common ancestor, and what the nose knows about antibiotics, with Devi Shastri.

 The Endangered Species Act—a 1973 U.S. law designed to protect animals in the country from extinction—may need a fresh look. The focus on “species” is the problem. This has become especially clear when it comes to wolves—recent genetic information has led to government agencies moving to delist the grey wolf. Robert Wayne helps untangle the wolf family tree and talks us through how a better understanding of wolf genetics may trouble their protected status.

Despite concerns about antibiotic resistance, it seems like antimicrobials have crept into everything—from hand soap to toothpaste, and even fabrics. What does the ubiquitous presence of these compounds mean for our microbiomes? Alyson Yee talks with host Sarah Crespi about one antimicrobial in particular—triclosan—which has been partially banned in the European Union.

 As we learn more and more about exoplanets, we find we know less and less about what were thought of as the basics: why planets are where they are in relation to their stars and how they formed. Kevin Wagner joins host Sarah Crespi to talk about the latest unexpected exoplanet—a young jovian planet in a three-star system.
