We kick off this universe's first episode of CTP with a perusal of some recent science news:

- the first visual images of exoplanets

- a meteor that exploded, showering debris over the Canadian countryside - and a new treatment for deep vein thrombosis (DVT) involving ultrasound

Then we get heavy with a discussion of the Large Hadron Collider (LHC), the biggest and most expensive science project ever constructed. But not just scientists are interested in this giant toy, the internet is awash with claims of the impending destruction that the LHC will unleash - so we decided to get in on this action. There are heaps of references for this but we recommend starting with the LHC's page at CERN (the guys who built the thing):

Another good reference is:

Panthers are apparently running amok in the Australian outback. Given that none of us has ever seen one of these thousands of vicous predators, and the outragous improbability of them existing at all, we thought we'd take a closer look.

Popculture: Spore, the computer game by Will Wright, has generated a lot of heat in evolution/anti-evolution circles as well as with the average gamer. We fired up the old PC and got down to business.

We roundout the show with a quiz.

Oops. Mistakes we shouldn't have made but did:

When talking about the way anti-matter is used in Positron Emission Tomography (PET) we said that they probably contain the anti-matter using magnetic fields before it is used in the PET scan. While magnetic fields are used to contain anti-matter that is not the practice for PET scans. Actually, the patient is injected with a radioactive isotope of oxygen, carbon or fluorine. This isotope then decays, emitting a positron, which is the anti-particle of an electron. We cover this is detail in Episode 2.
