Today in "They can, but should they?" news, science has learned how to create memories in a piece of brain tissue isolated in a test tube,
which sounds exactly like the plot of a science fiction nightmare because it totally is. Neuroscientists at the Case Western Reserve University School of Medicine
isolated fragments of rodent brain tissue in vitro
, and, by stimulating neural pathways in the tissue, were able to induce a variety of simple memories in it. Those memories were only persistent for 10 seconds or so, but to a living piece of brain in a jar, that 10 seconds probably felt like a billion lifetimes, so there's that.
