Giaquinto leads ORNL’s Nuclear Analytical Chemistry and Isotopics Laboratory, which makes critical contributions to nuclear forensics and nonproliferation. Specialized team uses nuclear forensics to solve mysteries and safeguard materials A group of nuclear detectives at the Department of Energy's Oak Ridge National Laboratory takes on tough challenges, from detecting illicit uranium using isotopic "fingerprints" to investigating Presidential assassination conspiracies. "A very big capability at Oak Ridge exists for nuclear analytics, all the way from helping commercial production of nuclear power to making sure the world's nuclear materials are properly accounted for," said ORNL's Joseph Giaquinto, leader of the Nuclear Analytical Chemi...

Eyewitness identification reforms  may have unintended consequences Research by a University of California, Riverside psychologist raises serious questions about eyewitness identification procedures that are being adopted by police departments across the United States.  These new procedures are designed to reduce the kinds of false identification errors that can lead to wrongful convictions of innocent people. While it has long been held that these changes reduce false identifications with little or no loss of correct identifications, UC Riverside psychology professor Steven E. Clark suggests that that is not the case. The loss of correct identifications can be significant, Clark says. Importantly, the new procedures may, under some circumstances, lead to identification evidence that is less accurate than the identification evidence from the procedures they are designed to replace. Policymakers need to look very carefully at the data from empirical studies as they c...

Credit: Kyoto University    Using virtual three-dimensional mazes together with functional magnetic resonance imaging (fMRI), researchers from Kyoto University investigated whether a person's preconceptions could be represented in brain activity. Ever had the experience of receiving details instructions on how to do something, then get it mixed up and confused? According to this research out of the University of Kyoto, this confusion may be due to the way our brain maintains our preconceived ideas.  Our preconceived ideas are hard to shake, so we end up mixing up our preconceptions with the instructions.  Result?  Confusion. So how does this apply to writers?  Suppose you're writing a murder mystery, and your bad guy has an accomplice who is given specific instructions on setting up the bad guy's alibi.  Your detective can't break the bad guy.  But the accomplice?  Did he do exactly as instructed?  Or did he make a mis...

Thomas Jefferson and his stand-up desk. Søren Kierkegaard wrote standing. As did Charles Dickens. And Winston Churchill. Philip Roth. Add to that Vladimir Nabokov and Virginia Woolf. Plus Ernest Hemingway. What are we waiting for? *  *  *  *  * New study indicates students' cognitive  functioning improves when using standing desk s Donald Rumsfeld.  (Okay, so not a writer.  But he worked standing.) Do students think best when on their feet? New findings provide the first evidence of neurocognitive benefits of stand-height desks in classrooms. These findings provide the first evidence of neurocognitive benefits of stand-height desks in classrooms, where students are given the choice to stand or sit based on their preferences. Ranjana Mehta, Ph.D., assistant professor at the Texas A&M School of Public Health, researched freshman high school students with who used standing desks. Testing was performed at the ...

As a science geek, I do watch the many true-crime shows, especially those that rely on forensic science to identify and convict culprits.  But as this latest series of reports indicate, the science isn't perfect, in fact in some cases, the science is plainly flawed. Fortunately, researchers and defense attorneys are aware of the flaws and can use this information to help protect the truly innocent. Here's another report on a flaw in forensics with suggestions on how to correctly us eyewitness testimony.  The full report is available in the attribution line. *  *  *  *  * Using eyewitness identifications:  New report urges caution A new report from the National Research Council recommends best practices that law enforcement agencies and courts should follow to improve the likelihood that eyewitness identifications used in criminal cases will be accurate. Science has provided an increasingly clear picture of the inherent limits in human v...

Forensic sciences are 'fraught with error' " People tend to seek, perceive, interpret, and create new  evidence in ways that verify their preexisting beliefs ." Researchers review various high-profile false convictions and provide an overview of classic psychological research on expectancy and observer effects and indicates in which ways forensic science examiners may be influenced by information such as confessions, eyewitness identification, and graphical evidence. A target article recently published in Journal of Applied Research in Memory and Cognition (JARMAC) reviews various high-profile false convictions. It provides an overview of classic psychological research on expectancy and observer effects and indicates in which ways forensic science examiners may be influenced by information such as confessions, eyewitness identification, and graphical evidence. Objective evidence is actually subjective The target article authors, Saul Kassin and Jeff Kuk...

www.pjstar.com At least 24 men convicted or charged with murder or rape based on bite marks on the flesh of victims have been exonerated since 2000, many after spending more than a decade in prison. Source : The Peoria Journal Star.   Bite-mark analysis can lead to false convictions Since 2000, at least 25 people convicted on bite-mark evidence  have been exonerated due to advances in DNA testing. Forensic science is a vital crime-fighting tool in today's criminal justice system. But it can also lead to false convictions, according to H. David Sheets, PhD. Landmark research by the Canisius College physics professor proves that bite-mark analysis is "far from an exact science." Bite-mark analysis compares the teeth of crime suspects to bite-mark patterns on victims. Historically, forensic odontologists (dentists who provide forensic dental identifications in criminal investigations and mass disasters) operate under two general guidelines when interpr...
