"Witness testimony has been the gold standard of the criminal justice system, revered in courtrooms and crime dramas as the evidence that clinches a case. Yet scientists have long cautioned that the brain is not a filing cabinet, storing memories in a way that they can be pulled out, consulted and returned intact. Memory is not so much a record of the past as a rough sketch that can be modified even by the simple act of telling the story. For scientists, memory has been on trial for decades, and courts and public opinion are only now catching up with the verdict. It has come as little surprise to researchers that about 75 percent of DNA-based exonerations have come in cases where witnesses got it wrong. This month, the Supreme Court heard its first oral arguments in more than three decades that question the validity of using witness testimony, in a case involving a New Hampshire man convicted of theft, accused by a woman who saw him from a distance in the dead of night. And in August the New Jersey Supreme Court set new rules to cope with failings in witness accounts, during an appeal by a man picked from a photo lineup, and convicted of manslaughter and weapons possession in a 2003 fatal shooting. Rather than the centerpiece of prosecution, witness testimony should be viewed more like trace evidence, scientists say, with the same fragility and vulnerability to contamination. Why is a witness's account so often unreliable? Partly because the brain does not have a knack for retaining many specifics and is highly susceptible to suggestion. "Memory is weak in eyewitness situations because it's overloaded," said Barbara Tversky, a psychology professor at Columbia University's Teachers College in New York. "An event happens so fast, and when the police question you, you probably weren't concentrating on the details they're asking about." "

"Prosecutors here noted that she is also in the vanguard of a growing trial trend: in Arizona, Hawaii, Idaho, Indiana and some other states in the last few years, courts have allowed such trained dogs to offer children and other vulnerable witnesses nuzzling solace in front of juries. The new role for dogs as testimony enablers can, however, raise thorny legal questions. Defense lawyers argue that the dogs may unfairly sway jurors with their cuteness and the natural empathy they attract, whether a witness is telling the truth or not, and some prosecutors insist that the courtroom dogs can be a crucial comfort to those enduring the ordeal of testifying, especially children. The new witness-stand role for dogs in several states began in 2003, when the prosecution won permission for a dog named Jeeter with a beige button nose to help in a sexual assault case in Seattle. "Sometimes the dog means the difference between a conviction and an acquittal," said Ellen O'Neill-Stephens, a prosecutor there who has become a campaigner for the dog-in-court cause. "

""If it disagrees with experiment, it is wrong." Richard Feynman - Nobel-winning physics icon, curiosity champion, graphic novel hero, bongo drummer, wager-maker, no ordinary genius - would have been 94 today. To celebrate, here is one of Feynman's most beloved classics, a 1964 lecture in which he distills with equal parts wit and wisdom the essence of the scientific method:"

Can we trust the memory of court witnesses?

"IN a great many fields, researchers would give their eyeteeth to have a direct glimpse of the past. Instead, they generally have to piece together remote conditions using remnants like weathered fossils, decaying parchments or mummified remains. Cosmology, the study of the origin and evolution of the universe, is different. It is the one arena in which we can actually witness history. Enlarge This Image Brendan Monroe The pinpoints of starlight we see with the naked eye are photons that have been streaming toward us for a few years or a few thousand. The light from more distant objects, captured by powerful telescopes, has been traveling toward us far longer than that, sometimes for billions of years. When we look at such ancient light, we are seeing - literally - ancient times. "

"We are, I believe, witnessing something new in American politics. Last year, looking at claims that we can cut taxes, avoid cuts to any popular program and still balance the budget, I observed that Republicans seemed to have lost interest in the war on terror and shifted focus to the war on arithmetic. But now the G.O.P. has moved on to an even bigger project: the war on logic. "

An entire concept of psychology, Bystander Intervention, developed based on a single news story of a single murder, that of Kitty Genovese in 1964. Some are now suggesting the original story doesn't fit the model to which it gave birth.
