SPOILER ALERT: if you haven’t listened to Radiolab's new Speed show yet, go do that right now, before you read any further. Then, take a look at some mind-bending behind-the-scenes images from the physicist in our "Master of the Universe" story.

We don't know about you, but we've got a giant trampoline, a burger refill denied, and buffaloing English grammar on our minds...

Josh King, corporate communications executive, former director of production for presidential events in the Clinton White House and host of the podcast "Polioptics," picks apart the body language, stagecraft, and other subtle elements of last night's debate.

For this New Sounds, we’ll hear music from Cape Verde, by a male pop-griot singer, Tcheka. He plays traditional percussive guitar and weaves the batuku style (a style traditional to the islands that was banned by the Portuguese, but continued by the women in the fields as they worked.) Plus, music for accordion and double-bass from Finland, and traditional music of West Java, featuring the kacapi, a boat-shaped zither.  And more.

It's that time of the month again for the new releases show on New Sounds. John Schaefer carefully separates the wheat from the chaff for this show.  He'll sort through the stacks of new CDs, the strange Soundcloud free-associations, and the highly anticipated digital submissions which have come across his desk and into his inbox over the past month to present some of the finest new releases. He'll skim off the cream. He'll pick the lentils from the ashes. You get it.

From the melodious inflections of phone messages, listen to a number of works sourcing voicemails, most from tape(!) on this New Sounds program. Hear Irish composer Roger Doyle’s “Memento Mori,” composed around intimate verbal time capsules culled from various answering machine messages of Doyle's family, close friends and partners, all of them recorded and preserved in the late 80's.

The Takeaway is launching a new podcast series with a distinct UK flavor, or as the English would write "flavour."  Chatter from America is an irreverent review of news and life in the United States, co-hosted by three ex-pat Brits. Every week The Economist's Matthew Bishop, Henry Timms from New York's famous 92nd Street Y and The Takeaway's Femi Oke analyze the news with only the occasional mention of cricket.

The U.S. Department of Homeland Security sent guidance to Immigration and Customs Enforcement (ICE) attorneys Thursday which clearly identified enforcement priorities among pending deportation cases. In short, it said who should be deported and who gets to stay.

A nation-wide network of young undocumented immigrants, their parents and their supporters in Congress are flocking to Alabama to protest that state’s harsh new anti-immigration law.

For this New Sounds podcast, listen to a live performance by the Alwan Arab Music Ensemble. It's a group of classical players, six members strong and based in New York, all of whom sing and play a wide range of Arab musical styles on traditional instruments.  Listen to Egyptian, Iraqi, and Syrian classical art music from Cairo, Baghdad, and the ancient city of Aleppo.  Plus, music from Syrian Abed Azrie.

For this New Sounds, we’ll sample liberally from the latest recording from Moroccan-born singer Amina Alaoui, called “Arco Iris.”  It’s a pan-Mediterranean blend of flamenco music from Spain, fado music from Portugal, Arab-Andalusian music and Brazilian choro, linked by jazz and a night in Tunisia.

Philip Glass’s piano works have had a longstanding and widespread influence – on the so-called Post-minimalist composers, but also on musicians working in the electronic dance world.  One of them is Francesco Tristano, who brings electronica’s repeating motifs back to the piano in his solo piece “The Melody.”  We’ll hear that, as well as several of William Duckworth’s “Time Curve Preludes,” often considered the first major Post-minimalist work, and a work from the late Canadian composer Ann Southam directly inspired by Glass’s piano works.

Diane Van Deren is one of the best ultra-runners in the world, and it all started with a seizure. In this short, Diane tells us how her disability gave rise to an extraordinary ability.

Are new ideas and new inventions inevitable? Are they driven by us or by a larger force of nature?

In this week's show, Ricky Gervais drops by Studio 360. And listening back to the tape, my stomach muscles are aching.

We couldn't wait until the weekend to share a piece of the interview. In this straight-from-the-studio preview, Gervais declares his love for
