Tech3Rs: A newsletter for animal technicians

Tech3Rs is our regular newsletter providing animal technicians with the latest news from the NC3Rs. Each issue features updates on recent advances in the 3Rs and highlights new resources, research and events that we think will be of interest to animal technicians. Download the latest issue now or read on to find out more.

Electronic copies

Each issue of Tech3Rs will be available online to download on this page. We will place a banner in our NC3Rs newsletter to alert subscribers to new editions. If you haven't done so yet, register now for the monthly NC3Rs newsletter and look out for the Tech3Rs banner every three months.

We will also be printing hard copies of each issue which we can post out to animal research facilities across the UK. If you would like to request hard copies for your institution, please email us at
