50 years ago, Tim Bliss and Terje Lømo worked in the Oslo lab of the late neuroscientist Per Andersen, where they made a momentous discovery: the fact that when a neuron signals to another neuron frequently enough, the second one will later respond more strongly to new signals for hours afterwards. The phenomenon is called long-term potentiation (LTP) and it’s fundamental to how we learn and remember. @KnowableMag talked to Bliss and Lømo about their discovery, and to other neuroscientists about how they’re applying knowledge about LTP to their research about memory disorders, chronic pain and more.

American prisons run on forced labor. For @bolts, historian Robert Chase answered reader questions about the legal basis for paying incarcerated people below minimum wage, whether the Americans with Disabilities Act applies in these circumstances, who has the authority to stop prison labor, and more.
