Big Picture Science for March 26, 2018 - Skeptic Check: Your Inner Lab Coat













Big Picture Science - Skeptic Check: Your Inner Lab Coat

ENCORE: Sherlock Holmes doesn’t have a science degree, yet he thinks rationally – like a scientist. You can too! Learn the secrets of being irritatingly logical from the most famous sleuth on Baker Street. Plus, discover why animal trackers 100,000 years ago may have been the first scientists, and what we can learn from about deductive reasoning from today’s African trackers.

Also, the author of a book on teaching physics to your dog provides tips for unleashing your inner scientist, even if you hated science in school.

And newly-minted scientists imagine classes they wish were available to them as grad students, such as “You Can’t Save the World 101.”

Big Picture Science for March 19, 2018 - The X-Flies












Big Picture Science - The X-Flies

Insect populations are declining.  But before you say “good riddance,” consider that insects are the cornerstone of many ecosystems.  They are dinner for numerous animal species and are essential pollinators.   Mammals are loved, but they are not indispensable.  Insects are.

Meanwhile, marvel at the extraordinary capabilities of some insects.  The zany aerial maneuvers of the fly are studied by pilots.  And, contrary to the bad press, cockroaches are very clean creatures.  Also, take a listen as we host some Madagascar hissing cockroaches in our studio (yes, they audibly hiss).

Plus, how insects first evolved … and the challenges in controlling lethal ones.  Are genetically-engineering mosquitoes the best way to combat malaria?

Guests:
  • Erica McAlister – Entomologist, Senior Curator of diptera in the Department of Entomology, Natural History Museum in London, author of “The Secret Life of Flies
  • Jessica Ware – Evolutionary biologist and entomologist at Rutgers University
  • Anthony James – Vector biologist, University of California, Irvine
  • Lauren Esposito – Arachnologist, California Academy of Sciences, San Francisco

Big Picture Science for March 12, 2018 - Shell on Earth












Big Picture Science - Shell on Earth

ENCORE: We all may retreat to our protective shells, but evolution has perfected the calcite variety to give some critters permanent defense against predators.  So why did squids and octopuses lose their shells?  Find out what these cephalopods gained by giving up the shell game.

Plus why Chesapeake Bay oyster shells are shells of their former selves.  What explains the absence of the dinner-plate sized oysters of 500,000 years ago, and how conservation paleobiology is probing deep time for strategies to bring back these monster mollusks.

Also, was the Earth once encased in a giant, continental shell?  A new theory of plate tectonics.  Land ho!

Guests:
Rowan Lockwood – Conservation paleobiologist at the College of William and Mary.
Al Tanner – Ph.D. student in paleobiology at the University of Bristol, U.K.
Mike Brown – Professor of Geology, University of Maryland

Big Picture Science for March 05, 2018 - Space: Why Go There?












Big Picture Science - Space: Why Go There?

It takes a lot of energy and technology to leave terra firma. But why rocket into space when there’s so much to be done on Earth?  From the practical usefulness of satellites to the thrill of exploring other worlds, let us count the ways.

The launch of a NOAA weather satellite to join its twin provides unparalleled observation of storms, wildfires, and even lightning.  Find out what it’s like to watch hurricanes form from space.

Meanwhile, more than a dozen countries want their own satellites to help solve real-world problems, including tracking disease.  Learn how one woman is helping make space accessible to everyone.

Plus, now that we’ve completed our grand tour of the Solar System, which bodies are targets for return missions and which for human exploration?

Guests:
  • Sarah Cruddas – Space journalist, broadcaster, and author based in the U.K.
  • Jamese Sims – GOES-R Project Manager at NOAA
  • Danielle Wood – Assistant professor, MIT Media Lab, Director of the Space Enabled Research Group
  • Jim Green – NASA Planetary Science Division Director
