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

Folge vom 22.09.2016Podcast: An atmospheric pacemaker skips a beat, a religious edict that spawned fat chickens, and knocking out the ‘sixth sense’A quick change in chickens’ genes as a result of 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.

Folge vom 15.09.2016Podcast: A burning body experiment, prehistoric hunting dogs, and seeding life on other planetsNews 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.

Folge vom 08.09.2016Podcast: Double navigation in desert ants, pollution in the brain, and dating deal breakersNews 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.
