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.

“The cost of Trump’s executive disorder is measured in lives” is the headline of this piece in @thecontinent. The team at the Africa-wide weekly newspaper break down how the U.S. government’s freeze on international aid has affected HIV and tuberculosis programs in Uganda, Mozambique, Zimbabwe and the Democratic Republic of the Congo. “American aid to the global HIV response is channelled through the President’s Emergency Plan for AIDS Relief (Pepfar). It is the world’s biggest HIV response fund and it supports – or supported – up to 20-million people,” they write.
