PETA goes for shock and awe, COK aims for compassion, and IDA defends and protects. These are just a handful of animal rights groups who have pioneered the animal rights field. They’ve saved, rescued, fed, thrown paint at fur wearing socialites and fashionistas, and have brought light some of the most horrific animal cruelty videos known. Following in their footsteps is a new venture brought to you by the Germans behind GoPubMed, called Go3R. Go3R is a semantic search engine for alternative methods to animal experiments and testing. The name comes from the Three R’s Principle which posits the principle ways inhumanity can be removed: Replacement, Reduction, and Refinement. Enter a search term, and filter by various methods, including top categories, time and place. A slew of medical articles will populate and you have your choice of reading.
