Carrie Leonetti, University of Auckland By helping identify perpetrators and the remains of victims, forensic DNA analysis holds enormous power to solve crimes. It also has enormous implications for privacy and fairness. But with science and society changing at such a pace, the law can struggle to keep up. It is now 25 years since New Zealand’s Criminal … Read More

[avatar user=”duncansteel” size=”thumbnail” align=”right” /] There are perennial arguments about the circumstances of the assassination of President Kennedy in 1963, and in particular whether more than one shooter is required by the evidence (such as the Zapruder film). Those who know little about physics frequently claim that the sharp backwards motion of JFK’s head as the fatal shot hit him … Read More

By Katherine Holt Anna Sandiford has written before about how she uses pollen in her forensic science work after watching an episode of ‘Bones’. Pollen also offers a world of other exciting opportunities – from searching for oil or preventing ‘honey fraud’, to tracking goods or fighting the war on drugs. As a palynologist (pollen scientist) I started my career reconstructing … Read More

A couple of weeks ago I came across a TV version of The Poisoner’s Handbook on Sky TV’s History channel. The Poisoner’s Handbook is an excellent book which both Grant and I have previously reviewed (see here and here). It provides a fascinating insight into the development of forensic science in the early 20th century. I was going … Read More

The ridiculously high tech forensic equipment shown on programmes such as CSI always amuses me, with enhancement technologies and their mass spectrometers, gas chromatographs etc which spit out conclusive results within about five minutes. Here is a wonderful parody that makes fun of these exaggerations of the capabilities of forensic analysis. http://www.youtube.com/watch?v=4WYKrjcwQXQ&feature=grec_index … Read More

As chemists throughout the world have studied the occurrence of different elemental isotopes and developed new techniques to measure the proportions of isotopes present in different parts of the world, this knowledge has developed into a useful tool for forensic scientists. Referred to as isoscapes, a merging of “isotope” with “landscape” this field allows the geographical origin of a sample … Read More

In the age of CSI-style crime dramas it is difficult to imagine a time when DNA evidence wasn’t part of any criminal investigation. But the first court case in New Zealand where DNA evidence was presented happened only as recently as 1990 and on the world stage, the first case involving DNA profiling went to court in the United Kingdom … Read More
