This is SCIENCE FRIDAY. I'm Ira Flatow. Your telephone is a computer, really. Your microwave, it's got a computer in it. Your television, it's got a computer there. Even, of course, your computer has a computer. Your iPhone, your cellphone. Everything - just about everything in electronics these days has a computer, and they all work the same way like a Turing machine. Decades before your PC, your Mac or your Commodore, Alan Turing was designing a machine which could calculate almost anything: a universal computer.
This is SCIENCE FRIDAY. I'm Ira Flatow. This weekend, three members of the crew onboard the International Space Station will be returning to Earth after over six months in orbit. Flora Lichtman had a chance to chat with some of them, and she's here with us. Hi, Flora.
FLORA LICHTMAN, BYLINE: Hi, Ira. That's right, just another day at SCIENCE FRIDAY, calling space.
Peter Parker and Gwen Stacy hit the big screen again next week. The new movie "The Amazing Spider-Man" opens on July 3rd. And once you accept the premise that a man can get super spidey skills from a radioactive - sorry to laugh - spider bite, well, you know, just like Johnny Carson used to say, you buy the premise, you buy the bit.
This is SCIENCE FRIDAY; I'm Ira Flatow. Imagine walking through Times Square, and every step you take it converted into a tiny electric current by the special pavement underfoot. Now multiply by the third of a million people who walk through Times Square on any given day. Wow, it could be a pretty awesome source of renewable energy, right, perhaps enough to power all those neon lights and flashing billboards.
Julian Assange will defy a British Police notice to surrender. A member of his defense fund said the WikiLeaks founder will remain in the Ecuadorian Embassy in London because asylum law take precedence over an extradition order.
Saying he was afraid of persecution from the United States government and that his extradition to Sweden could hasten that, Assange has sought refuge and asylum from Ecuador.
Supreme Court Chief Justice John Roberts surprised the country yesterday by siding with the liberal wing of the court in the health care decision.
Roberts was appointed by President George W. Bush and has reliably taken conservative positions. But after yesterday's decision, you can bet his welcome from conservatives who saw him as a hero has chilled.
Speaking to a conference of judges and lawyers outside of Pittsburg, Roberts acknowledged his predicament.
Buddhists donate food and other necessities to monks as a way of earning merit for future lives. Monks have refused donations of alms from the military as a political protest in 1990 and 2007, a boycott that some monks insist is still in effect.
Nay Myo Zin is a former captain in the Myanmar army who now runs a charity and is a political activist. He says he quit the army because soldiers were "always made to do bad things," and thus preventing him from properly practicing his Buddhist religion.
In response to political reforms in Myanmar — also known as Burma — the U.S. and other Western countries have eased some sanctions targeting the country's former military rulers.
But so far, one of the most powerful institutions inside the country has kept its sanctions in place. For some time, Myanmar's Buddhist clergy have effectively been on a spiritual strike by refusing to take donations from the military — a serious blow to the former regime's legitimacy.
A group of young adults in Wichita has created an initiative to help promote the city as a cultural and commercial destination.
The project is called From Wichita With Love and was created by a group of local friends. After attending a conference, the group was inspired to come up with innovative ways to attract attention to Wichita.
They designed a retro-inspired postcard and last week distributed thousands of them to area shops, bars and venues.
Switching gears now to a subject that also inspires passion around the world, the finals are set at Euro 2012. That's Europe's big national team soccer tournament. It's being held in Ukraine and Poland this year. Italy got into the final, thanks to two goals from the striker, Mario Balotelli.
Now we turn to presidential politics in Mexico. Americans are not the only people electing a new president this year. Mexicans are heading to the voting booth on Sunday. The frontrunner is Enrique Pena Nieto of the Institutional Revolutionary Party, also known as the PRI. That party dominated politics in Mexico for decades until a relatively recent time. The candidate in second place is Andres Manuel Lopez Obrador. He is with the Democratic Revolution Party.
