This week - how innovative software could cut acoustic hotspots from buildings. Plus - the plight of the honey bee, and also how the internet can help as a teaching aid.

Acoustic innovation

Adam Walton discusses innovative new software which is being developed in Wales that is designed to isolate acoustic "hotspots" in new buildings. The software being developed at Cardiff University, uses a "hearing map" designed to simulate what people would hear when standing in a particular position within a building. Professor John Culling of Cardiff University's School of Psychology explains how it works.

The plight of the honey bee

We're joined by Wally Shaw an ecologist and beekeeper from Anglesey, who is giving a talk at the Bangor science cafe event on Wednesday 14th April at the Blue Sky Cafe. The talk entitled "Dear honey bee, what have we done to you?" will outline how our relationship with the honey bee has changed over the past century or so, and led to a decline in their numbers.

Analysing the ice

Adam chats to Professor David Thomas of Bangor University's School of Ocean Sciences about his recent expedition to Greenland with an international team of scientists studying the role of sea ice in regulating oxygen and carbon dioxide concentrations in the Arctic atmosphere and surface waters.

Study net

We hear from parenting expert Anne Coates about the effectiveness of using the internet as a teaching tool.
