Light micrograph section through the skin of a patient with epidermolysis bullosa (EB) showing cleavage of part of the epidermis. EB is a rare genetic disease of the connective tissues in the skin and mucosal membranes. In this condition, no collagen forms between the skin layers (the dermis and epidermis). This allows them to move across each other at the slightest pressure, resulting in blisters and painful sores. Hematoxylin and eosin stain. Magnification: x550 when printed at 10 centimetres wide.

Illustration of CAR (chimeric antigen receptor) T cell immunotherapy, a process that is being developed to treat cancer. T cells (one at centre), part of the body's immune system, are taken from the patient and have their DNA (deoxyribonucleic acid) modified by viruses (spiky spheres) so that they produce chimeric antigen receptor (CAR) proteins. These proteins will be specific to the patient's cancer. The modified T cells are then multiplied in the laboratory before being reintroduced to the patient.
