Wales' new chief scientific adviser, Prof Julie Williams, says the country needs more scientists.

Prof Williams is spending her first day in the job.

The Merthyr-born academic was appointed a CBE for her Alzheimer's research at the School of Medicine in Cardiff, and her appointment was announced last month.

The chief scientific adviser for Wales provides independent scientific advice to the first minister and the Welsh government.

The role was previously filled by Prof John Harries who retired earlier this year.

Prof Williams has previously urged children to see science as "great fun".

She wants to encourage youngsters to "think carefully" when choosing their subjects, and says a science discipline "may be the basis of a very interesting job".
