Arduino Workshop 61 mins – “Akkana Peck (@akkakk) joins Elecia White to talk about an introduction to Arduino workshop for high school students. Arduino boards are a fantastic way to encourage people into embedded systems. The boards are cheap, the starter kits are great, there are lots of things you can do with them, and the compiler software is free. Akkana’s site (Shallow Sky) has the workshop outline, going from morning general activities to afternoon specific ones. The really simple circuit for the photo-theremin we had on the show is linked from there (and the latest code is on github). A separate post describes the the cheap motor boards she’s been working on, including the specific chips (including the H-bridge)….” At the link right-click “Download MP3” and select “Save Link As” from the pop-up menu.

Brain Mapping 15 mins – “Ten months ago, a group of researchers proposed a “large-scale, international public effort [that] aimed at reconstructing the full record of neural activity across complete neural circuits. This technological challenge,” they said, “could prove to be an invaluable step toward understanding fundamental and pathological brain processes.” The group called this proposed effort “the Brain Activity Map Project,” [PDF] and in March, it spelled out its vision in an article in the journal ACS Nano. Last week, President Obama put the weight of the U.S. federal government behind the idea, creating what he called the BRAIN Initiative, where the letters B-R-A-I-N stand for Brain Research through Advancing Innovative Neurotechnologies….” At the link right-click “download podcast” and select “Save Link As” from the pop-up menu.
Cartoon Creators 18 mins – “Layout artists create a painstaking works of art that allow viewers to instantly register where they are and what mood they’re supposed to feel—and then animators plop their drawings right on top of them. The dynamic is kind of like the straight man in a comedy duo—layout artists set up the gags, but it’s usually the animators who get the glory. Layout artists are, both figuratively and literally, working in the background. Even though Maurice Noble never drew characters, he was able to cultivate a distinctive style in his landscapes.” At the link right-click “Download” and select “Save Link As” from the pop-up menu.
City Concerns 17 mins – “…it seems obvious that cities are bad for the environment. They’re dirty, noisy concentrators of people and pollution. They suck up natural resources from the countryside and spit back out vast quantities of waste, human and otherwise. What could be less natural than these inland oceans of concrete? And yet, in what might be the most sustained attempt to question that common wisdom, a new book published last month argues that the weight of our scientific knowledge falls the other way. By and large, cities are environmental pluses, and the more densely populated they are, the more beneficial they are….”At the link right-click “download podcast” and select “Save Link As” from the pop-up menu.

Cyberthreat Culture 5 mins – “Israel is a country at the forefront of cyber security technologies. That’s no big surprise, considering the number of Israeli soldiers trained in the art of cyber-warfare. When they leave the military, many of them get jobs protecting business, infrastructure and commerce from the kinds of attacks they themselves knew as soldiers.

Elephant Poaching 51 mins – “Efforts to halt the slaughter of African elephants have been far less successful than many had hoped. An international ban on the elephant ivory trade was put in place in 1989. Elephant populations began to rebound. But ivory traders exploited loopholes and poachers became more efficient – and more brazen – in their methods. Today, poachers kill as many as 35,000 elephants a year. Conservationists warn that unless more is done, those great land mammals could become extinct. For this month’s Environmental Outlook, guest host Tom Gjelten and a panel of  experts discuss how to stop the elephant ivory trade.” You can listen at the link, but not download; however, the file is included in the zip collection noted in the introduction to this episode.

Fukushima Review 9 mins -(2 parts) “In the days and weeks after a massive tsunami led to a triple meltdown at the Fukushima Daiichi nuclear power plant on March 11, 2011, Japan launched many investigations into what went wrong that terrible day. But most of those inquiries were linked, in one way or another, to Japan’s nuclear industry or its government. So Yoichi Funabashi, a former journalist who once headed one of Japan’s leading news organizations, decided what was needed was a truly independent investigation.” At the link right-click “Download” and select “Save Link As” from the pop-up menu. part 2 “In the weeks before the third anniversary of the Fukushima Daiichi nuclear power plant disaster on March 11, 2011, PBS NewsHour sent science correspondent Miles O’Brien to Japan to report three Fukushima-related stories, then on to the Philippines for additional stories. O’Brien had expected that the riskiest part of his trip would be his visit to the highly-contaminated Fukushima plant. But then in the Philippines, as he was loading his car, a heavy box of video gear fell on his arm. It hurt more than it should have and before he knew it … well, let’s get first to what O’Brien reported in his series for NewsHour.

Gun Safety Technology 14 mins – “The United States is currently engaged in a vibrant national debate about guns, gun violence, and the balance between gun regulations and the right to bear arms. But surprisingly little is being said about the various technologies that might be deployed to reduce the hazard of guns while safeguarding the freedoms of gun owners. There are a number of potential biometric controls—ways that guns can be made to fail to fire if they don’t recognize the person holding them. Could they have spared the life or well-being of a Sandy Hook student? An Aurora moviegoer? A Tucson congresswoman?

History of Time 53 mins – “…In this episode, we look at the changing ways Americans have experienced the 24-hour day — from pre-industrial times right on up through today’s era of time-shifted media. Along with their guests, Peter, Ed, and Brian examine the role of economic forces in shaping our relationship with the clock – like the powerful Gilded Age railroad officials who got together in 1883 and carved the continental U.S. into five time zones, introducing Americans to the idea of “standard time.” And they explore how people have experienced the rhythm of night and day — and why the advent of electric lighting changed that rhythm forever. And finally, they ask, is unlimited time always a good thing? A loving look at basketball’s iconic “shot-clock” offers answers.

Jones Act 15 mins – “If you want to send a bunch of oranges by truck from Florida to Baltimore, no one cares who made the truck. Or if you want to fly computer chips across the country, it’s fine if the plane is made in France. But if you want send cargo by ship, there’s a law that the ship has to be American made. Here’s why: a 90-year-old law, called the Jones Act. Every time you want to send something from one US port to another, the cargo must travel on a ship built in the US, staffed by mostly Americans, and flying the American flag. Today on the show, we look at the all the unexpected places this law pops up: on cruise ships, cattle farms, and in New Jersey, where a guy really, really needs salt.” At the link find the title, “#524: Me and Mr. Jones,” right-click “Media files npr_289634788.mp3” and select “Save Link As” from the pop-up menu.

But the U.S. suddenly has a lot of natural gas too – a flood unleashed in a handful of boom years of fracking. Now, with Russian troops all over and around Crimea and Ukraine, the call has gone up for the United States to unleash American natural gas exports and cut Russia’s energy leverage down to size. Environmentalists say watch out. American manufacturers, too – warning of higher prices. But the push is on.

Recycling Evolves 4 mins – “Susan Collins, president of the Container Recycling Institute in Los Angeles, wants to correct a fairy tale many of us like to believe about recycling. “The public has been trained to put their stuff in their bin at the curb, and for the stuff to just go away. And of course there is no such thing as away, away is always somewhere,” Collins says. Somewhere, for more than a decade, has most often been China. Chinese recycling plants have made a lot of money reprocessing our trash and selling the raw materials. But around a quarter of the bottles, cans, and paper we were sending there were getting mixed in with too much food and trash, or even comingled with the wrong type of recycling. The bottles, cans, and cardboard that couldn’t be recycled ended up in Chinese landfills. Last year, China decided it’d had enough of being the world’s trash dump.

Robots and Jobs 17 mins -“For half a century, we’ve watched as computers, sensors, and robots have eliminated jobs—sometimes entire job categories—but also been responsible for them. Sometimes both. For example, technology created 350,000 telephone operators, only to lose them. By the way, that’s roughly the same number of people employed at—take your pick—HP, Panasonic, or Samsung, plus Intel. For decades, it’s been generally believed that the effect is net positive, that is, that technology has always created more jobs than it’s destroyed.

On the one side of the argument are voices like that of business tycoon Richard Branson, no stranger to managing tens of thousands of employees, who quickly blogged on the matter and tweeted, “Perplexed by Yahoo stopping remote working.
