Cicadas live underground and emerge in 13- or 17-year cycles.
Here's an example of a finished DIY soil temperature sensor
WNYC is asking "armchair scientists, lovers of nature and DIY makers" to help predict the emergency of cicadas in the Northeast by building a temperature sensor like this one. As the results come in, WNYC will map out the findings and share them online.
Back in 1996, a group of baby cicadas burrowed into soils in the eastern U.S. to lead a quiet life of constant darkness and a diet of roots. Now at the ripe age of 17, those little cicadas are all grown up and it's time to molt, procreate and die while annoying a few million humans with their constant chirping in the process.
NPR Science Correspondent Richard Harris traveled to Australia's Great Barrier Reef to find out how the coral reefs are coping with increased water temperature and increasing ocean acidity, brought about by our burning of fossil fuels. Day 5: A return to shore finds that people prefer cars to corals.
It's not every day you open an in-flight magazine and read an ad touting "spitwater pressure cleaners for the mining industry." Flip the page and you'll also see an ad cajoling you to "snorkel, sip, snooze" on the Great Barrier Reef.
The Republican and Democratic parties have been in a digital arms race for years. And this week, Republicans frankly admitted that they are losing.
Now, the GOP has ambitious plans to improve its game.
Monday's report from the Republican National Committee puts it bluntly: "Republicans must catch up on how we utilize technology in our campaigns. The Obama team is several years ahead of everyone else in its technological advantage."
This is SCIENCE FRIDAY. I'm John Dankosky. Some 30,000 people die on U.S. roads every year, but the highway isn't just dangerous for us humans. Scientists estimate that our cars and trucks kill 80 million birds a year. That's 80 million. That death toll is high enough, they say, that it's turning out to be a powerful force of natural selection. In fact, some birds may be evolving shorter wings to let them navigate traffic more safely. That's according to a paper out this week in the journal Current Biology.
This is SCIENCE FRIDAY. I'm John Dankosky. Ira Flatow is out this week. Last December, Steven Coughlin, an epidemiologist at the Veterans Affairs Office of Public Health, resigned his position. And last week he told a congressional subcommittee why. He had serious ethical concerns about the research being done on Gulf War Illness at the VA.
This is SCIENCE FRIDAY. I'm John Dankosky. It sounds like something from a science fiction movie, researchers using cutting-edge biotech methods to bring an extinct species back to life. As a matter of fact, I think I saw that one. It was called "Jurassic Park."
Babies as young as nine months appear to approve of people who like what they like — and approve of being mean to those who don't share their tastes. Kiley Hamlin, lead author of a study in the journal Psychological Science, discusses the importance of similarity to young children.

In his book Grand Central: How A Train Station Transformed America, New York Times urban affairs correspondent Sam Roberts writes of the scientific innovations pioneered at New York City's Grand Central Terminal, such as electric commuter trains and standardized time.
Ken Caldeira of the Carnegie Institution for Science takes a water sample during his experiment out on part of the Great Barrier Reef. The water is slightly pink because his team is using a dye to trace an acid-neutralizing chemical as it flows across the reef.

Caldeira (left) tosses some plastic tubing that will pipe in the antacid, mixed with nontoxic red dye, from a floating tank nearby to see whether the reef will grow faster under less-acidic conditions.

NPR Science Correspondent Richard Harris traveled to Australia's Great Barrier Reef to find out how the coral reefs are coping with increased water temperature and increasing ocean acidity, brought about by our burning of fossil fuels. Day 4: Richard catches up with one of the gurus of climate science out on the reef.
Ken Caldeira loves a challenge, and he has a big one right under his feet. He's standing on an expanse of coral reef out in Australia's Great Barrier Reef. It's being washed with water as the tide streams over the reef, from a lagoon to the open sea.
