Power to the People

ENCORE  Let there be light! Well, it’s easy to do: just flip a switch. But it took more than the invention of the light bulb to make that possible. It required new technology for the distribution of electricity. And that came, not so much from Thomas Edison, but from a Serbian genius named Nikola Tesla.

Hear his story plus ideas on what might be the breakthrough energy innovations of the future. Perhaps hydrogen-fueled cars, nuclear fusion electrical generators or even orbiting solar cells?

Plus, a reminder of cutting-edge technology back in Napoleon’s day: lighthouses.

•   Michael Dunne – Physicist, program director for laser fusion energy, Lawrence Livermore National Laboratory

Melty dunes

Cosmic Diary by Lori Fenton - March 18, 2015

A Piece of Mars: With all due apologies to followers of the show Coupling, I have to call these things “melty dunes”. This link shows what a crisp dune should look like. The dunes in this 600×450 m (0.37×0.28 mi) scene, however, have rounded crests and sand that seems to have ponded around the bottom of the dunes. These are common at high southern latitudes on Mars.

Microbes: Resistance is Futile

You are what you eat. Whether you dine on kimchi, carnitas, or corn dogs determines which microbes live in your stomach. And gut microbes make up only part of your total microbiome.

Find out how your microbes are the brains-without-brains that affect your health and even your mood. Also, why you and your cohorts are closer than you thought: new research suggests that you swap and adopt bugs from your social set.

Plus, the philosophical questions that are arise when we realize that we have more microbial DNA than human DNA.

And a woman who skipped soap and shampoo for a month to see what would grow on her.

•   Beth Archie – Biologist at the University of Notre Dame

•   Nada Gligorov – Assistant professor of medical education at Mount Sinai Hospital
