Silent witness: New analytical approaches to advance and enhance the forensic value of human hair. The Australian criminal justice system is under ever-increasing scrutiny with recent threats to national security. Courtroom evidence is expected to carry an objective indication of its value, largely as a result of the success and widespread application of DNA evidence. This is problematic for conventional human hair evidence which has traditionally been presented as the expert opinion of a hair e ....Silent witness: New analytical approaches to advance and enhance the forensic value of human hair. The Australian criminal justice system is under ever-increasing scrutiny with recent threats to national security. Courtroom evidence is expected to carry an objective indication of its value, largely as a result of the success and widespread application of DNA evidence. This is problematic for conventional human hair evidence which has traditionally been presented as the expert opinion of a hair examiner who has conducted a microscopic comparison. A recent wrongful conviction in Canada and an associated Royal Commission has highlighted these problems. A comprehensive new hair examination sequence employing objective techniques will increase the forensic value of human hair, one of the most common evidence types found at crime scenes.Read moreRead less
Discovery of new genes for plant cellulose biosynthesis and improved fibre production. Cellulose, the world's most abundant biopolymer, is important to the cotton and forest industries and for human and animal nutrition. Before biotechnology can manipulate cellulose, we must identify the enzymes of the synthesis pathway and understand how their properties determine the properties of the cellulose they produce. Not all enzymes are known and any relationships to cellulose properties remain unexplo ....Discovery of new genes for plant cellulose biosynthesis and improved fibre production. Cellulose, the world's most abundant biopolymer, is important to the cotton and forest industries and for human and animal nutrition. Before biotechnology can manipulate cellulose, we must identify the enzymes of the synthesis pathway and understand how their properties determine the properties of the cellulose they produce. Not all enzymes are known and any relationships to cellulose properties remain unexplored. This study extends our successful mutational analysis of cellulose synthesis in Arabidopsis and initiates the molecular analysis of organisms making cellulose with distinctive properties. It will significantly advance knowledge of cellulose biosynthesis and identify novel genes for fibre improvement.Read moreRead less
