New research on the autoimmune disease systemic lupus erythematosus (SLE) provides hints to the origins of the puzzling disorder. The results were published in Nature Immunology. In people with SLE, their B cells – part of the immune system – are abnormally activated. That makes them produce antibodies that react against their own tissues, causing…

For the first time, a team of neuroscientists from Columbia University have controlled a visual behavior of a mouse by activating a few neurons in its visual cortex. In their study, published in Cell, the researchers demonstrated that specific groups of neurons, known as neuronal ensembles, have a causal role in behavior. The researchers used…
