Smell is probably the oldest sense, hardwired right into our brains and closely linked to memory. Now researchers are trying to unravel the complex genetics that underpin it. Plus, contagious dog genital cancers, gene therapy for blindness, and a rather slimy gene of the month.

01:02 – How do I smell?
Stuart Firestein, Professor of Biology at Columbia University, explained to me how our sense of smell works, and why its so important
09:16 – Gene therapy for blindness
Researchers have carried out a small but successful trial of gene therapy for a type of blindness.
14:41 – Genes and schizophrenia
US researchers have pinpointed new genetic variations linked to
the psychiatric condition schizophrenia
15:50 – Sequencing the coral community
Japanese researchers have analysed the genes in a whole coral community, including the corals and the organisms living on them
17:00 – Scent of a maggot
At the University of Manchester, Professor Matthew Cobb and his team are studying how maggots smell things.
24:39 – How does the polymerase chain reaction work?
Polymerase Chain Reaction – how does it work? I’ve read a brief explanation
on Wikipedia, but it seemed more to describe the heating cycles scientists go through without, explaining how copies of DNA are produced and amplified.
27:49 – Gene of the month – Escargot
Our gene of the month is Escargot, named after the French word for snail, but also known by the less exotic name Fleabag.
