Miles Ahead

For several years, environmental advocacy groups have been fighting to ban the pesticide chlorpyrifos from agricultural use. A turnover in leadership at the EPA has led to a moment of indecision on what to do about the chemical. Robert Sapolsky is a neuroscientist who's spent a long time assisting in the legal battle against chlorpyrifos. We discussed the devastating effects of chlorpyrifos on an exposed nervous system as well as his work to discredit the industry science claiming its safety.

After years of exhaustive research linking the pesticide chlorpyrifos to a host of developmental and cognitive deficiencies in children, the EPA was poised to ban the chemical in November 2016. But something else happened that same month; the election of Donald Trump. As a result, this potent neurotoxin is still in use. Miriam Rotkin-Ellman is a senior scientist for the Natural Resources Defense Council, which is still fighting for a ban.

Artificial Intelligence (AI) is not off in the distant future... in some ways it is already here. How is AI already changing our lives? Does it work independently of us or does it also have our all-too-human biases? After hashing out machine learning on Episode 19, Brian and Fedor sit down with Picasa founder and serial tech entrepreneur Lars Perkins to discuss AI in broader strokes on this special edition of Miles To Go.

Communicating the science of climate change, with its overwhelming expert consensus, seems like it should be easy. However, a science-averse media and strong fossil fuel lobby make it exceedingly difficult. Climatologist Michael Mann and cartoonist Tom Toles have teamed up to put climate change in context in their new book, The Madhouse Effect: How Climate Change Denial Is Threatening Our Planet, Destroying Our Politics, and Driving Us Crazy. I talked to both of them at this year's Annapolis Book Festival.

What is machine learning? How does it work? What are these artificially intelligent algorithms useful for? Considering they are used by Amazon, Google, Netflix, Facebook and many other companies we interact with on a daily basis, what are the benefits and drawbacks? Thanks to a listener suggestion, we decided to delve deeper on the subject. Miles O'Brien Productions team members Brian Truglio and Fedor Kossakovski are joined by producer and coder Cameron Hickey to hash it out on this special edition of Miles To Go.

Methane is a much more potent greenhouse gas than Carbon Dioxide. It is more short-lived than CO2 (about a decade as opposed a century), but it is 85 times more effective at warming. Robert Green is a world-renowned expert in spectroscopy, which is a great way to find methane on distant planets, but also ours, as I learned in this interview.

In the final episode in our series on Junk News, some wisdom from one of the leading experts in the murky world of online misinformation. He also happens to be the producer of the series that we aired on the PBS NewsHour. Now he's taking the software he wrote to Harvard, where they hope to find new ways to combat Junk News. I hope you enjoy this talk with Cameron Hickey, my friend and soon-to-be former colleague.

Facebook was created for people to share family photos and memories. But as ads entered the mix, the platform was refined to hold our attention for as long as possible. Quality was not a consideration - until recently. But how to fix the junk news mess without editing it? Maybe Facebook needs a newsroom.

The Internet was supposed to provide a utopian virtual world where all of us could come together in peace, love and harmony to better understand each other and our differing viewpoints…

But we got derailed on the road to utopia, didn't we? Eli Pariser, the man who coined the phrase "filter bubble", knows as much about this as anyone. I hope you enjoy the conversation as much as I did.
