1451 Dublin is this year hosting the "City of Science 2012". Its Ambassador, Vince McCarthy, chats on what it’s all about.

Dublin won the bid to host this major science conference, he said. Attendees – including international researchers, policy maker and business leaders - will discuss the big questions that "we’re looking to answer in society".

To celebrate that, a year-long programme of events will be taking place.

Mr McCarthy said the big benefit of hosting the event is the opportunity to showcase the high-quality science culture we have in Ireland. It brings science to the public, he said, and shows that science is part of their everyday lives.

He said the benefit of the Young Scientist Exhibition is that it taps into, at a young age, people's innate curiosity into the world around.

It helps them understand how science can answer those questions and ultimately improve their lives. Audio here

1432 Science teacher Catriona Mahony, of Davis College Mallow, sees the practical benefits for students of entering the competition.

"The student is the big winner,'' she said. ''It's a fantastic introduction into how to carry out investigations during the Junior Cycle.''

She said students benefit from "independent thinking'', which is part of the process when researching a project.

From a teacher’s point of view, she said the competition is a good way of building a good rapport with students, in addition to creating a ''great buzz'' in the school. Audio here
