Understanding each technique’s advantages and disadvantages, and tailoring their use to best address the specific research question under consideration, is key. One of our series of Reports on Progress.
Scientists have reported promosing rejuvenation experiments on mouse brains — but it isn’t clear that such results can be translated usefully into human therapies.
Now that researchers have the technology to test the hypothesis that myelin is a simple, regular axonal insulator, they find it isn’t true. Now the fun begins.

Deaf people who learned American Sign Language first show differences in brain structure compared with deaf people who learned to lip-read English first.
As the political environment heats up, the leadership qualities of potential candidates are under the public microscope.
