Artificial intelligence (AI) is playing an ever growing role in physics – from medical imaging and materials to quantum tech, astrophysics and beyond. But AI is not purely code and algorithms. The racial and gender biases in society are mirrored and sometimes amplified by AI, which can then rebound on people in turn. In a powerful new feature, science writer Julianna Photopoulos explores issues of bias in AI – and discovers what physicists are doing to recognize and tackle the problem.

Edinburgh Instruments application note: Raman microscopy of graphene   Confocal Raman microscopy can be used for determining the number of layers of graphene in a sample. This application note shows how Raman mapping can produce images that reveal areas of the sample which are high in disorder. The RM5 Raman Microscope's high spatial and spectral resolution allows for high-quality graphene analysis, the perfect tool for any materials scientist.
