New technology pins criminals to gun crimes.> It is getting more difficult for criminals to get away with breaking the law. If a gun is used it is now possible to match the gunshot residue to specific bullet cartridges. A criminal will probably keep some unused cartridges at his/her home. The shooter will have residue on this body and the gun anyway. Each batch of bullets has a different chemical makeup. Differing amounts of glass fragments is the main difference. Sensitive High Resolution Ion Microprobe (SHRIMP) and Time of Flight Secondary Ion Mass Spectrometry (ToF-SIMS) provide extremely detailed analysis of gunshot residue. When a gun is fired, residue to splattered everywhere, on the shooter, the victim and in the wound itself. There is no way of destroying the evidence. Residue can be matched with bullets at a certainty of 99 per cent. It is possible that some innocent people jailed for crimes will be shown to be not guilty with the used of the new techn...

New technology automates sexing of chicks. Fattening up male chicks is a waste of resources. Furthermore, having to manually check the sex of chicks that are sold to producers is a costly burden. There must be an easier way. In Europe a way of determining the sex of chicks while still in the egg will revolutionize the industry. Female chickens fatten up much quicker than males. Moreover, males do not lay eggs. It may be possible to on-sale the "rejected" eggs for production of egg powder. The new system is 95 per cent effective after the ninth day of gestation. The way male chicks are disposed of at present is not pretty: they are crushed alive by an industrial crusher. At first, Wouter Bruins of the Netherlands had the aim of ending this mass euthanizing. Now it is seen as a potential extremely profitable enterprise. Sexing can be done at the rate of 4,500 an hour. ◆ Technology by Ty Buchanan   ◆ Tys Countr y Amusing Animal Photos Odd Weird Thin...

Technology: Scramjet is tested at Woomera. Technology never stands still. Mankind progressed very slowly for centuries, but now things move forward at a rapid pace. Air transport could change dramatically in coming decades. The US and Australia are testing a hypersonic rocket that can travel at five times the speed of sound. Because of the angle of liftoff, together with takeoff and landing speeds, you couldn't really enjoy a lunch and drink while sitting in your seat. Woomera in South Australia is the busy testing site. The project is not aimed at space flight. Passenger travel is the main goal. A journey from London to Sydney is estimated to take two hours. The arduous passage though would mean taking your meal preferably after the flight. Australia helped develop the scramjet which uses oxygen from the atmosphere for power as the jet rockets upward. Consequently, it does not have to carry heavy and expensive fuel. Tests began in 2009. Norway and Germany are ...

The number of school students doing maths and science is woefully inadequate in city areas. Numbers in rural areas are even worse! A new plan is in progress to improve the situation. Unfortunately, it will prove to be a total failure and waste of money. Culture has inertia. It takes about half a century to alter established beliefs. Rural children believe that maths and science are too difficult for them so they do not even attempt them. They stay with the social subjects. The new "curative" program to solve the matter will ignore city students and concentrate on rural regions. There is a noticeably low number of rural students doing education, engineering and science degrees.  Note that 74 per cent of teachers in city areas have STEM experience, while only 17 per cent of rural teachers have done STEM work.  The intention is to send high quality STEM (Science, Technology, Engineering and Math) teachers to the bush - they will love that! It is like sending the...

There is nothing worse than parking in a shopping center car park, doing your shopping, then coming out to find another driver has reversed out and scraped your rear "bumper" A compulsory radar reversing system should be introduced for all vehicles. VicRoads is doing something about this. Their maintenance fleet has been fitted with radar-based reverse braking technology. The main target is not vehicle damage: it is injuries to employees who are hit when trucks are reversing. No less than 18 workers were struck from 2003 to 2012. The system detects anything directly in the reversing path of a vehicle. All new motor vehicles are now fitted with such technology in Europe, the US and Japan. Where is Australia with regard to this? It can prevent injuries, save lives and last but not least stop unwanted damage.  Insurance companies could even offer lower premiums as a result. VicRoads will share its trial data with others involved in the transport industry. I...

Get ready for the dole queue as technology puts more people out of work. Even traditional occupations such as law is to be taken over by computers doing routine work. Nearly half of the workforce is predicted to lose their jobs. This is frightening and will be devastating to the economy and society. It seems that efficient technology will take over menial tasks. While it is conceivable that routine work will be done by computers, it is questionable whether laboring tasks will. Even laboring takes a conscious mind to wield the shovel. We do not yet have human-sized robots smart enough to do this. Automated combine harvesters are one thing, but robotised fence repairers - I think not! Australia could make the mistake of hanging on to old ways of making money. Primary products have been the major source for earning foreign exchange for a couple of centuries. Primary products will always be needed. Australia must change, however, to accept new ways of doing things in a ...

Despite claims that battery technology will improve over the next few years, the battery has remained the same for half a century. Sure base materials that make the battery store electricity have changed, but not that much in recent years. All the same battery technology Due to mass production and increasing demand the price of batteries will fall. This is just economics really. The cost of Solar has fallen 80 per cent in five years. Don't expect batteries for your phone or tablet to fall this much though. The great hope is that advances in solar technology in electrical catchment and storage can be "transferred" to other products. Communication and motor vehicle manufacturers could be putting too much faith in this, however. It may not happen. Batteries can be charged in a matter of minutes now. The future could see people carrying a "spare" mobile phone power pack in their pocket. Exchange stations could spread and be ubiquitous everywhe...

With today's technology why can't an artificial pancreas be put into a patient's body? Well, now it can! Xavier Hames is only four years old. Autoimmune disease has destroyed his pancreas. An artificial one is working very well indeed inside his body. The artificial pancreas is more a computer than a body organ. It monitors low insulin levels, even predicting its future trends, then controls insulin delivery. It is particularly useful as night when external insulin treatment can fail resulting in a coma. Preparations are in train to implant another artificial pancreas in an adult, Jane Reid. This could mean an end to eight jabs a day to test blood levels of insulin and continuous injections to control it.  This could save governments millions of dollars in the long term. ✴  Health by Ty Buchanan  ✴ http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blogspot.com/ http://adventure--australia.blogspot.com/atom.xml . . . . . ....

Environmental researchers do not have to take the kitchen sink with them on field trips any more. They can leave GPS, camera and notepad behind as they do their work. New software makes this possible. A single device linked to the Internet now has everything an investigator requires. This is especially so in mining. The Northern Territory has adopted the new system and it is doing all it promises.  As farming takes up new technology it would be expected that researchers would do the same. Capturing information is now very easy indeed with reports being done automatically. Photographs are coordinated with Google Earth maps. Relevant data is also stored.  In depth analysis is now possible with the extra time on hand for investigators. A researchers movement around a site is recorded. This makes monitoring of tasks much easier. The software is a significant step forward. Hours of tedious labor has been reduced.  With a solid data bank in hand, looking...
