Young Scientist Invents New Fingerprint Recovery Mechanism After Home Burglary

What sounds like the story from a Hollywood crime show is actually a real story originating from Australia. A young scientist, Dr Kang Liang, comes home one day to find his house burglarized. The thief got away with some of his favourite belongings and frustrated by the law enforcers limitations he uses his knowledge of science to create a new and improved method for fingerprint capturing.

The new process allows forensic investigators to use a new liquid instead of the old fashioned dusting technique. The liquid contains luminescent crystals that bond to the residue and become visible with UV light. The new technique will allow to take high-resolution digital images of the fingerprint and get much better and detailed images than previously possible. To get the same results, the item with the fingerprint currently needs to be shipped to a special lab where it will be heat and vacuum treated and thereby.

With this new method, investigators can take high-resolution digital photos of the fingerprints right away and transfer them digitally to a central for processing and matchmaking. This could save days if not weeks in investigations and eventually even save lives in some cases.

CSIRO said in a statement: “As far as we know, it’s the first time that these extremely porous metal organic framework crystals have been researched for forensics,” and they are now looking to partner with police forces around the Australia. A thing that I’m sure will spread around the world shortly thereafter, also aided by a large news outlet such as The Sydney Morning Herald bringing this news to everyone.

While the new process won’t help Dr Kang Liang of CSIRO in his own case and get his things back, it might make things a lot more difficult for any other criminal out there.

Is E-Ink The Future of Remote Controlled Traffic Signs?

Wouldn’t it be better to have signs that change themselves when you want to if you live in a city with a lot of traffic or events? Sydney’s State of New South Wales’ Road and Maritime Services seems to agree and started using Visionect’s digital signage to help with all the traffic changes happening around the city.

Sydney is well-known for having a lot of football and cricket matches events, so on those days, drivers are faced with a hectic traffic. Up until now, RMS used to put up and take down different signs to show traffic changes, but since they started using the e-ink signs, they say things just got a lot faster and easier.

The e-ink displays were used for the signs due to the fact that they use a lot less power, so hooking them up to a solar-powered battery wouldn’t be a problem. The signs are also equipped with wireless broadband and can be updated remotely, so you can update and turn them on or off with the press of a button. Now imagine placing them, taking them down and changing them manually… it’s a really great improvement, isn’t it?

For now, RMS rolled out 15 of these signs on George Street in the Sydney CBD and some in Moore Park area. However, the signs are so time and cost efficient that they can almost replace every sign which requires to be changed every now and then to reflect traffic changes. Will this be the future of traffic signs? What do you think?

Uber Under Fire After Raising Prices in Sydney

Uber has been under fire today after the ride sharing app put prices up in Sydney following the alleged terrorist hostage crisis in the city. The app raised prices in the Sydney area before quickly backtracking.

Prices were raised up to 4 times the normal rate, according to the BBC. The company responded to the backlash by refunding some customers and offering free rides out of the Sydney central business district. They also tweeted that the price hike was to encourage more drivers to get in the area to help people get home.

“We are all concerned with the events happening in Sydney. Uber Sydney will be providing free rides out of the CBD to help Sydneysiders get home safely. Our thoughts are with those affected and the NSW Police Force. We are in the process of refunding rides.” – Uber.

Scientists Work Out How To 3D Print Vascular Networks

3D Printing has come a long way, from objects to food and now even human skin and meat. One of the major problems when attempting to print human meat was printing out the vascular network, meaning all the blood vessels and ventricles. However, it appears that even the latter problem has been recently solved by scientists from the University of Sydney, Harvard, Stanford and MIT.

The scientists have apparently solved the problem by creating a skeleton of vessels, which was then used as a basis to grow human cells around it. Once the process was complete and stable, the scientists dissolved the 3D printed material, leaving only the vascular network.

“Imagine being able to walk into a hospital and have a full organ printed – or bio-printed, as we call it – with all the cells, proteins and blood vessels in the right place, simply by pushing the ‘print’ button in your computer screen,” said Dr. Luiz Bertassoni of the University of Sydney. “While recreating little parts of tissues in the lab is something that we have already been able to do, the possibility of printing three-dimensional tissues with functional blood capillaries in the blink of an eye is a game changer.”

Building vascular networks is a big thing, but using them is even greater than imagined. It appears that the vessels are then used to transport nutrients through bioprinted tissue in order to achieve better cell differentiation and growth. Summing it all up, scientists are now able to create ‘organs’ in the lab, having the scientists believe that this will eventually lead to true organ regeneration.
