African Swine fever is deadly to pigs and is spreading west from Russia across Europe. The virus that causes it is very resilient and can stick around on clothing, hay and in infected pork products for as long as 150 days. Biosecurity is crucial to preventing its arrival in the UK. If just one pig eats some infected meat from discarded human food the disease could quickly spread causing thousands of pigs to be culled and costing the industry millions. But what is the current progress on developing a vaccine? Adam talks to virologist Professor Jonathan Ball of Nottingham University and Zoe Davies from the National Pig Association.
Simon Boxall from Southampton Oceanography Centre gives an update on the sinking of the oil tanker Sanchi and its environmental impact.
CRISPR is a revolutionary gene editing technique which can modify DNA and has the potential to correct genetic errors in a range of human diseases - even cancer. The technique has only been around for a few years but is already being talked about as a Nobel prize winning candidate. The market for the technology has been predicted to be worth US$ 10 billion by 2025. But stocks took a wobble last week on news that our immune system may render CRISPR useless. Is there really a big problem? Adam talks to Matt Porteus from Stanford University who did the research.
18 months ago, New Zealand announced a conservation project to exterminate all vermin that are decimating the indigenous bird population. For millions of years, the flora and fauna evolved in isolation, without predatory mammals. When humans arrived, they brought with them a host of bird-eating animals like rats, stoats and possums which now kill 25 million native birds every year. Marnie Chesterton travelled to New Zealand to report on a campaign of mass poisoning to save the kiwis and the kakapos and asks whether it’s ethical to kill one species to save another.
And Cat Hobaiter from St Andrews University responds to listener questions about how chimpanzees might recognise family members.
