• Doing Science at the Edge of the Earth

  Some scientific discoveries take place in a lab. Others are made deep in the rainforest, along the ocean floor or on the dark side of the moon. And still others are made squelching through mud and ice on the northernmost island on Earth… at least, if you’re NPR climate correspondent Alejandra Borunda. Two summers ago, Alejandra followed an expedition of scientists to Greenland’s Inuit Qeqertaat, or Kaffeeklubben (“Coffee Club”) Island. The researchers with her were aiming to find what plants grew at the farthest north point of the island. Along the way, she had an adventure … and witnessed the good, the bad and the muddy realities of scientific expeditions.Interested in more exploratory science?

• Solved: The Potato Origin Mystery

  Usually, when two different species mate, it’s a disaster. At least, that’s what scientists had generally thought about hybrids, the offspring of these unions. But some researchers are starting to change their view as they learn of more beneficial hybrid events. The Atlantic science journalist Katie Wu details two of these hybridization examples: one in desert frogs and one in two ancient plants that > led to the modern potato.Interested in more biology episodes?

• The Science Of Fear And Horror Movies

  Creepy crawly season is upon us, Short Wavers! We're welcoming fall with a contemplation of fear and anxiety. In human history, fear kept us safe. It helped us flee from predators. Anxiety made us wary of potential dangers — like venturing into a known lion-infested area. But what happens when these feelings get out of hand in humans today? And why do some of us crave that feeling from scary movies or haunted houses?For answers, we talk to Arash Javanbakht, a psychiatrist from Wayne State University. He likes studying fear so much he wrote a whole book called Afraid. In this episode, Javanbakht gets into the differences between fear and anxiety, many of the reasons people feel afraid and why things like scary movies could even be therapeutic.

• What Are Flies Doing In The Middle Of The Ocean?

  In the North Sea — between the United Kingdom, Norway and Denmark — thousands of flies swarmed an oil rig. Engineer Craig Hannah noticed they’d stay still on the rig for hours, suddenly taking off all at once. He was seeing hoverflies. Often confused with bees, they’re unsung pollinators. And they migrate, often hundreds of miles – including, it seems, to the middle of the ocean. Today on the show: The mystery of why these insects are landing in the open ocean. Plus, a surprising finding in the Amazon rainforest and the sounds of life in a coral reef. Interested in more science behind skincare products?

• Why Animal Scavengers Protect Your Health

  Worldwide, populations of scavenging animals that feed on rotting carcasses are declining. Scientists are finding that this can seriously hurt human health. NPR science reporter Jonathan Lambert has been looking into how human health is intertwined with scavenging animals and why these animals’ decline could lead to more human disease. Today, he brings all he learned, including how conservation could help, to your earholes.Check out more of Jon’s reporting on scavengers and human health.Interested in more science behind skincare products?
