The Australian Federal Police is the federal police agency of the Commonwealth of Australia. Although the AFP was created by the amalgamation in 1979 of three Commonwealth law enforcement agencies, it traces its history from Commonwealth law enforcement agencies dating back to the federation of Australia's six precursor British self-governing colonies in 1901.The role of the AFP is to enforce Commonwealth of Australia criminal law and to protect Commonwealth and national interests from crime in Australia and overseas. The AFP is Australia's international law enforcement and policing representative, and the Government's chief source of advice on policing issues.Since 7 September 2009, the Commissioner of the Australian Federal Police has been Mr Tony Negus, who was sworn in following the retirement of the previous commissioner, Mick Keelty.

Commercially available skin cleansing alcohol wipes and conventional swabs were investigated for their use as a universal sampling medium for the simultaneous collection of both organic and inorganic explosive residues. Six compounds with the potential to be encountered in casework [pentaerythritol tetranitrate (PETN), 2,4,6-trinitrotoluene (TNT), hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX), triacetone triperoxide (TATP), ammonium nitrate, and sodium chlorate] were selected as representative target compounds. Quantities of these target compounds were deposited on four different substrates (glass, plastic, aluminium foil and laminate). Two chosen alcohol wipes demonstrated better overall performance in the recovery of both the organic and inorganic representative compounds from each of the test surfaces compared to the results obtained using conventional cotton and polyester swabs, pre-moistened with various solvents, and a direct methanol wash (used as a control). Results obtained using dry cotton swabs indicated that it was not an effective swabbing system for the collection of both organic and inorganic explosive residues on common substrates. © 2012 Elsevier Ireland Ltd.

Molecular biology has evolved far beyond that which could have been predicted at the time DNA identity testing was established. Indeed we should now perhaps be referring to "forensic molecular biology." Aside from DNA's established role in identifying the "who" in crime investigations, other developments in medical and developmental molecular biology are now ripe for application to forensic challenges. The impact of DNA methylation and other post-fertilization DNA modifications, plus the emerging role of small RNAs in the control of gene expression, is re-writing our understanding of human biology. It is apparent that these emerging technologies will expand forensic molecular biology to allow for inferences about "when" a crime took place and "what" took place. However, just as the introduction of DNA identity testing engendered many challenges, so the expansion of molecular biology into these domains will raise again the issues of scientific validity, interpretation, probative value, and infringement of personal liberties. This Commentary ponders some of these emerging issues, and presents some ideas on how they will affect the conduct of forensic molecular biology in the foreseeable future. © 2014 Gunn, Walsh and Roux.

Forensic DNA identification techniques are principally based on determination of the size or sequence of desired PCR products. The fragmentation of DNA templates or the structural modifications that can occur during the decomposition process can impact the outcomes of the analytical procedures. This study reviews the pathways involved in cell death and DNA decomposition and the subsequent difficulties these present in DNA analysis of degraded samples. © 2009 Elsevier Ireland Ltd.

There has long been speculation about who was behind the software written in 2009 under the Japanese-sounding name Satoshi Nakamoto, with various media outlets unsuccessfully trying to find out. Whoever is behind it likely wants to keep their identify secret as detractors say Bitcoin's use on the underground Silk Road website, where users could buy drugs and guns with it, could link them with criminal activity. Technology-focused websites Wired and Gizmodo have now both suggested Wright was responsible, saying he fit the creator's profile in nearly every detail, citing leaked documents. "The signs point to Craig Steven Wright, a man who never even made it onto any Nakamoto hunters' public list of candidates, yet fits the cryptocurrency creator's profile in nearly every detail," said Wired of its investigation. "Despite a massive trove of evidence, we still can't say with absolute certainty that the mystery is solved. "But two possibilities outweigh all others: Either Wright invented Bitcoin, or he's a brilliant hoaxer who very badly wants us to believe he did." On Wednesday, police raided a home in Sydney where Wright reportedly lived with his family. The Guardian Australia said police forced open the property with staff wearing white gloves seen from the street searching the cupboards and surfaces of the garage. "The Australian Federal Police can confirm it has conducted search warrants to assist the Australian Taxation Office at a residence in Gordon, Sydney," police said in a statement, without confirming it belonged to Wright. "This matter is unrelated to recent media reporting regarding the digital currency Bitcoin." The Australian Tax Office did not comment, citing confidentiality. Gizmodo reported that Wright and Dave Kleiman, an American computer forensics expert who died in 2013, were both involved in the development of the digital currency. It cited hacked emails and other documents, passed to its website, apparently showing Wright making repeated claims to being Satoshi Nakamoto over a period of years. None of the details could be verified by AFP. Tech entrepreneur Zhenya Tsvetnenko, who exchanged emails and then met Wright in Sydney about a possible business venture, said Wright was smart and knowledgeable enough to be Bitcoin's mastermind. "He was a very mysterious type of guy, he didn't say a whole lot," he told AFP, adding that he was "ultra intelligent". "The reason why I say it's not out of the question is he was in Bitcoin from the very beginning. I'm not sure he would like me saying that." Tsvetnenko said Wright was not only adamant that the cybercurrency's protocol "should be adopted and built up" but he also made a little joke about Bitcoin. When he asked how much of the virtual currency he had, Wright replied he had enough to buy a pizza. Within the Bitcoin community it is well known that the first ever purchase with the currency was a pizza. Satoshi Nakamoto was previously floated as the name of the person who originated the ingenious concept and the computer coding behind it. But no one ever saw the presumably pseudonymous creator—he, she or they only communicated on the Internet. Last year, Newsweek ran a cover story claiming reclusive engineer Dorian Satoshi Nakamoto was the mystery founder, but the Japanese-American denied any involvement. Bitcoins are generated by complex chains of interactions among a huge network of computers around the planet, and are not backed by any government or central bank, unlike traditional currencies. Its initial success has since met with a number of highly publicised setbacks. One of Bitcoin's biggest exchanges, the Tokyo-based MtGox, shuttered last year after admitting 850,000 coins—worth $480 million at the time—had disappeared from its digital vaults.
