05/05/26 Ash tree propagation, clinical waste on beach, DIY bat monitoring

A new propagation technique could help restore the ash tree to our landscapes. Scientists across the UK have been working to propagate saplings from resistant trees, but currently that takes between 2 and 5 years. Now researchers at the John Innes Centre have developed a speedier system, which they hope everyone could use, even at home, with the help of household bleach.

Campaigners are calling for a full-scale clean-up of beaches on the Isle of Sheppey in Kent following the discovery of a large quantity of illegally dumped clinical waste.

The University of Suffolk and a local group have been monitoring bats using bioacoustics to track their ultrasonic calls as they visit people's gardens.
