Welcome to the Being John Malkovich episode of scienceTASTIC, as we each take turns crawling into each other's heads and covering stories we think our co-hosts would pick. Mike (dressed up as Mark) delves into the phychology of the soccer penalty kick, Mark (doing a superb impression of Joe) demos a new portable sleeping cocoon, and Joe (wearing a Mike mask) explains how to make hydrogen fuel out of titanium leaves. The second half of the show is more like Vice Versa (or Like Father, Like Son if you're in more of a Dudley Moore-ish/Kirk Cameron-y kinda mood) as we once again swap minds and discuss animal chatter, space pee, and the eponymous English squirrels.

What we didn't get to: amputated hands, black holes, and discount space shuttles.

2009 may have been the International Year of Astronomy, but for our first show of 2010 we wanted to show that our support of the space sciences will continue. Mark counts down the top ten methods of deep space travel, Mike uses ESA's Herschel telescope to look back in time, and Joe asks for your vote on one of three proposed NASA missions. We also throw in a unique view of the aurora borealis, what could be your last chance to visit Seattle before it gets annihilated, and a new way to interface with your electronic devices. We're just a few days in and the new year is already looking scienceTASTIC.

What we didn't get to: fish with attitude, retinal implants, and the hip new slang term that's sweeping the nation.
