A new study published Thursday in Cell Stem Cell is set to further stoke the debate over whether our brain can actually grow back neurons as we age. The research found that people, even into their golden years, are regenerating their stock of neurons right up until the point of death—seemingly contradicting the results of a major study released just last month.

It’s difficult to imagine for many people, but for a certain percentage of the human population, music may evoke colors, words stir up flavors or sounds may even curl into shapes. This mash-up of senses is known as synesthesia and has baffled scientists for decades. Now, reports Michael Price at Science, researchers have identified some of the genes that may be responsible for these unusual experiences.

It’s often said that the loss of one sense improves the others. New research shows the dramatic extent to which this is true in blind people, and how their brains make new connections to boost hearing, smell, touch—and even cognitive functions such as memory and language.
