Forensic Analysis Developments

Mirroring the rapid evolution and ubiquity of technology over the last few decades, advances in technology has made sizeable contributions to the field of forensics. These manifest themselves not as entirely original technologies, but innovations in existing technologies in order to increase effectiveness and reduce costs. Some of these advances include:

Automated Sniffer Dogs

Police dogs such as bloodhounds are a legendary image of policework and forensics, and their ability to identify and track scents have made them invaluable police assets for decades. They are especially useful in the location and identification of cadavers. However they may soon become anachronistic, as Agile Technologies has developed a device that serves the same function with much more accurate readings. The Light-weight Analyzer for Buried Remains and Decomposition Odor Recognition, or LABRADOR for short, is an apparatus made up of 12 sensors that can identify 30 classes of chemicals that are emitted by decaying bodies. Using the visual display, the LABRADOR can identify bodies with a higher accuracy than dogs can, which can be misled by false readings by air and water movement. Operated like a metal detector, a LABRADOR can find a body buried in a 40 acre field to an accuracy of 15 metres. This drastically reduces the time and labour required to locate missing bodies, and removes the cost of raising and caring for specialized police dogs.

Fluorescent Fingerprint Enhancement

Forensic investigation of fingerprints has been a field of study for over 100 years, but improvements and evolutions of the technology are still emerging. The most common issue with fingerprints faced by forensic investigators are fingerprints that don’t have enough contrast or definition to give an accurate reading. To improve results, forensic scientists fume fingerprints with chemical compounds, most commonly cyanoacrylate (Super Glue). However, on a light coloured surface the fingerprint can still be too indistinct to take an effective photograph.

Until now, the solution has been to apply a second coat of a fluorescent chemical. However, these chemicals are toxic and must be applied in a controlled environment, which drastically increases the time and cost of a forensic investigation. There is also the inherent risk that this sequence will degrade and compromise a DNA reading. For three decades, research chemists have been trying to develop a safer, cheaper alternative. Developed by the French Laboratory of Supramolecular Photochemistry and the firm Crime Scene Technology, Lumicyano is a safe, inexpensive chemical innovation that benefits one of the most common methods of forensic investigation. Working as both a fluorescent and an adhesive, Lumicyano allows more accurate reading of fingerprints in a fraction of the time, using a basic UV light.

Forensic Glass Analysis

Laser Ablation Inductively Coupled Plasma Mass Spectrometry, or LA-ICP-MS for short, is in innovation in using broken glass as a forensic tool. While it may seem obscure, broken glass is often present in incidents such as burglaries and car accidents. By analyzing samples of broken glass at a crime scene, forensic scientists can establish such factors as the direction of a gunshot, tools used in a robbery or direction of an impact. With LA-ICP-MS, tiny trace samples of glass on skin and clothing can be traced back to broken windows at a crime scene, in a similar fashion to DNA evidence. LA-ICP-MS can break down glass samples to an atomic level, meaning that there is no limit to the size of sample used.

High-Speed Ballistics Photography

The refinement of high-speed digital cameras means that advanced camera forensics are now an easily accessible tool to forensic departments. High-speed cameras are used to test and match projectile trajectory, impacts and exit wounds and can be repeated at a low cost in order to establish a match with absolute certainty.

DNA Sequencing

The use of DNA in forensic analysis has been by far the greatest innovation in forensics of the last few decades. However it is not perfect, as DNA can degrade and some forms of samples leave gaps in necessary information. DNA testing is also a lengthy process, and can extend investigations by weeks or even months. DNA sequencers not only allow more comprehensive readings of DNA, the automation involved means that the labour involved is decreased by orders of magnitude.

Kids Magician Brisbane – Johnny the Jester Rocks!

Johnny the Jester is a professional Brisbane children’s magician who provides all sorts of fun forms of entertainment for children to enjoy. He has performed magic shows for kids in schools, shopping centres and other places around Brisbane. He’s also performed Christmas Day shows for the past few years at the Mater Childrens Hospital while also working for the Royal Brisbane Hospital Wonder Factory. He currently has his work open for birthday parties and other private events around the Brisbane area.

His magic show is filled with all sorts of illusions and tricks that kids will love but it’s his python that’s especially popular. His python is pretty long and can be safely placed around anyone’s shoulders. While he loves to showcase this big python, he also talks about things like what to do when people see such a snake in the wild and how pythons vary based on their appearances and where they live.

For the past fifteen years, Johnny the Jester has been working as a Kids Magician Brisbane who has performed for all sorts of kids in a variety of places in and around Brisbane. He’s even performed at Stockland and Westfield to name a few other places. Today he’s available for Brisbane children’s parties.

He’s especially great at charming snakes and getting them to relax. His skills make it easy for people to watch his python in action and to get up close and personal with it.

Parents can even take pictures of their kids playing with the huge snake. Photo opportunities are not only open but also encouraged. This will certainly be great for parents and kids alike considering how unique the python demonstration is.

Johnny’s magic shows last about an hour with fifteen minutes dedicated to his python show. He has plenty of fun and interactive things to show for children and even has a rabbit and a dove for his show. One of his favourite things when setting up his shows is to have his rabbit and dove disappear and come back. He has many other illusions for kids to watch too.

He’ll even supply party bags for all the kids at his events. These include all sorts of fun and magical party favours.

Parents who are interested in hiring Johnny the Jester for Brisbane children’s parties can watch one of his shows for free on Friday and Saturday nights before choosing to book him for their events. He performs on Friday nights at the Everton Park Hotel and Saturday nights at the Monier Hotel.

He can even be hired for adult parties as well. Johnny the Jester is available for corporate events, weddings and promotional events at trade shows among other places. While children are his key focus, he is willing to entertain anyone.

Parents can also find all sorts of additional party products from Johnny the Jester. Jumping castles, popcorn machines and cotton candy machines are all available for rent from his site. He offers these products to rent for any party in Brisbane but he especially encourages them for his shows to make them more memorable.

Parents who are looking to find some attractive entertainment options for Brisbane children’s parties should see what Johnny the Jester has to offer. Johnny has a number of fun things to bring out in his children’s parties and will certainly make any event more fun.
