Clinicians and scientists will today try to inspire S5 pupils in the Highlands who are considering a career in medicine or medical science.
Just over 100 pupils are attending the University of Aberdeen organised event which is one of a series the institution is staging to mark National Science and Engineering Week.
50 years of Medicine and Medical Science is the name of today's session which takes place in the Centre for Health Science in Inverness.
Professor Malcolm Laing, Associate Dean in Inverness of the University of Aberdeen Medical School, will welcome the teenagers and give a brief talk about medical innovation over recent years.
Researchers, surgeons and a GP will then deliver short presentations on what they consider to be the most important advances of their fields in recent times.
Topics covered include a look at infection and whether we will ever be rid of it; an overview of orthopaedics; research underway to tackle diabetes; an insight into what's new in surgery, and a discussion about contraception.
Pupils will then get the chance to vote electronically on what they believe to be the most important advance.
Hellen Matthews, Schools Project Officer at the University, said: "50 years of Medicine and Medical Science promises to be a really interesting, informative and interactive day.
"We hope that the range of topics covered by our experts will raise our audience's awareness of the diversity of careers available in medicine and medical science.
"As well as a look at past advances, it will also give them a great insight into where medicine and medical sciences might go in the next 50 years."
