There's No Such Thing As Cold

You've felt cold before. Sometimes it's cold outside. But what if I told you that "cold" isn't real? There's no substance or quantity called "cold" in science. We can't measure the amount of "cold" in something. Instead it's about what's NOT there.

The Longest Day

The Longest Day

Specialist maxillofacial surgeons Tim Martin and Sat Parmar prepare for a marathon operation on 53-year-old Teresa. Four weeks ago, Teresa was diagnosed with a fast-growing cancerous tumour in her face and she will die within weeks unless it is removed. The procedure involves radical surgery to the entire right-hand side of her face, and means she will lose both her upper jaw and right eye. It is an enormous undertaking for Teresa, and for Tim and Sat, too. Using 3D imaging, the team plan how to remove the tumour and, most importantly, how they will rebuild Teresa's face. Tim and Sat are all too aware that whilst removing the tumour will save her life, it will be devastating if she is left disfigured and unable to face the world. To give her the best possible outcome, they intend to fill the cavity left in Teresa's face with a section of bone and muscle removed from her hip, using a 3D-printed plastic guide that helps them cut out the correct shape bone.

Chris Packham: Asperger's and Me

Chris Packham: Asperger's and Me

Chris Packham invites us inside his autistic world to try to show what it is really like being him. For most of his life, broadcaster and naturalist Chris didn't tell anyone about the one thing that in many ways has defined his entire existence. Chris is autistic - he has Asperger's Syndrome, which means he struggles in social situations, has difficulty with human relationships and is, by his own admission, 'a little bit weird'. But what if there was a way of taking away these autistic traits? Would Chris ever choose to be 'normal'? Chris's long-term partner Charlotte discusses the problems Asperger's creates in their relationship, and Chris travels to America to witness radical therapies that appear to offer the possibility of entirely eradicating problematic autistic traits.
