New Zealand Earthquake

Before the earthquake on New Zealand’s South Island last September, the fault line it occurred on wasn’t even known about. Following the far more damaging and deadly aftershock which hit the city of Christchurch this week, there are concerns over whether it means the whole area is much more vulnerable than we previously thought. Quentin is joined by Dr Elisabetta Mariani, from Liverpool University, who has just returned from drilling the major fault line in New Zealand.
Grey Squirrel Control
Two thirds of people in the UK now think that grey squirrels should be controlled or even removed, according to a new survey by the European Squirrel Initiative. But how practical is it to stop this grey tide as it sweeps the red squirrel towards extinction? Quentin finds out more from Dr Craig Shuttleworth, an advisor to the European Squirrel Initiative.European Squirrel Initiative
Scott’s carbon animals
Tiny Antarctic marine creatures collected 100 years ago by Antarctic explorer Captain Robert Falcon Scott give new clues about change in polar animals. By comparing present-day bryozoans – a sea-bed filter-feeding animal that looks like branching twigs – with specimens from Scott’s expeditions, scientists have found the first conclusive evidence of increased carbon uptake and storage by Antarctic marine life. Lead author Dr David Barnes from the British Antarctic Survey joins Quentin to explain more.British Antarctic Survey: Dr David Barnes

The Royal Horticultural Society is announcing a new campaign to raise nearly £600,000 for a new research facility. The RHS is the only independent organisation that now funds research into gardening. The Office for National Statistics estimates that 4.3% of land use in England is domestic garden, so there is a real need for a dedicated centre devoted to horticultural research, says the RHS. Dr. Roger Williams, Head of Science at the Royal Horticultural Society, joins Quentin to explain more.
