Cephalopod Week 2019, Climate and Microbes, Puppy Eyes, Wave Energy. June 21, 2019, Part 1
For eight glorious days during the end of June, Science Friday honors the mighty mollusks of the ocean—Cephalopod Week returns for the sixth year! And we’re cephalo-brating with a tidal wave of ways for you to participate. This year, we want to know your favorite cephalopod. Is it the charismatic giant Pacific octopus or the long-lived chambered nautilus? Science Friday digital producer Lauren Young and biologist Diana Li add their own favorite cephalopods to the ultimate undersea showdown. They talk about the bizarre defenses of the blanket octopus, speedy squid getaways, and octopuses that play with LEGOs.
We may refer to Earth as “our planet,” but it really belongs to the microbes. All the plants and animals on Earth are relatively new additions to the planetary ecosystem. But despite living basically everywhere on the planet, and playing a role in many of the processes that affect the climate, the connection between microbes and the climate is often ignored. That needs to change, says a consensus statement published this week by researchers in the journal Nature Reviews: Microbiology. Take the issue of methane emissions from agriculture, particularly beef production. “The methane doesn’t come from the cows,” said David Mark Welch, director of the Division of Research at the Marine Biological Laboratory at Woods Hole. “It comes from microbes in the cows.” In a similar way, emissions coming from rice paddies aren’t caused by the rice—they are caused by microbes living in stagnant water around the rice. David Mark Welch, one of the co-authors of the consensus statement, joins Ira to discuss the deep connections between microorganisms and the climate, and why scientists and policymakers should pay more attention to microbes in the climate arena.
If you’ve ever suspected your dog of looking extra cute to get a bite of your steak or pizza, it’s probably because you couldn’t resist their puppy dog eyes. Over time, dogs have evolved to make their eyes look bigger and more baby-like. In a study published in the Proceedings of the National Academy of Science, researchers have discovered that dogs have muscles around their eyes that help them make puppy dog eyes at you. They also found that wolves, the wild ancestor of the dog, don’t have these muscles. Anne Burrows, one of the researchers in their study, joins Ira to discuss how dogs have evolved these muscles and why people are so susceptible to their big, sad-looking eyes. Sarah-Elizabeth Byosiere also joins to talk about other ways that dogs have evolved to strengthen the human-dog bond.
A renewable energy project planned off the coast of Newport is taking a step forward. Oregon State University has submitted a final license application for a wave energy testing facility with the Federal Energy Regulatory Commission. If built, it would be the largest of its kind in the United States. Oregon’s potential to use the motion of the waves to generate electricity is very high. But nationally, the development of wave energy has lagged behind other green energy sources. Part of the delay is the time and expense involved in permitting new technology. Not only do companies have to pay to develop this kind of clean tech, they also have to go through a lengthy and expensive permitting process before being allowed to see if their ideas work in the real world. This is where Oregon State University’s PacWave South Project comes in. The university plans to create a wave energy testing facility about six miles off the Oregon Coast. The idea is that energy developers will be able to by-pass the permitting and just pay the University to test their wave energy converters in the water.
