What science reveals about the reliability of eyewitness memory The malleability of memory once cast doubt on eyewitness identification in criminal cases, but new research reveals how eyewitness memory can be used accurately By Stephanie Pappas edited by Claire Cameron Human memory is, at its core, an unreliable witness. More than 70 percent of all convictions of people who were exonerated with DNA evidence between 1989 and 2019 were cases of mistaken eyewitness identification. Meanwhile decades

The achievement is impressive and raises obvious fears: Could AI, in the not-too-distant future, make viruses more deadly than those seen in nature? T
