Researchers at Brown University have developed a way to create "mini brains" – 3D arrangements of neural tissue that are able to transmit electrical synapses – that, at 25 cents apiece after fixed costs, could provide an efficient means of conducting neuroscience research.
With a pivotal role in fending off infections and disease, white blood cells are the engine room of the body's immune system. But little was known about what happens exactly when these cells reach the end of their life cycles. Scientists have now captured the death of white blood cells on camera for the first time, showing that they eject much of their contents while decomposing. One reason for this could be to warn neighboring cells of dangerous pathogens in the area. The researchers say learning more about their expiration could help bring about improved health treatments in the future.
