THE BEST
Scientists from the University of Leeds, in England, have created a technique to generate hi-resolution, colour 3D images of a piece of tissue. The images can be rotated on a computer screen and examined from any angle. Cancer Research UK said the technology could help researchers understand how cancer grew and spread, and learn how to treat it more effectively. These findings have been published in the American Journal of Pathology.In many applications this three-dimensional nature is important as it will help provide much more information than a simple 2D scan, creating a realistic image that a researcher can manipulate and spin around. This may help spot small tumours that could be missed by conventional approaches and if there is a major blood vessel fairly nearby, it will be possible to see if a tumour has reached it. And if it has not, it can be probably cut out safely.
It is the same with organs. If a surgeon wants to remove a tumour near a very sensitive organ, the main question is about the safety of the procedure. A tumour is a complex three-dimensional 'organ' made of cancerous and healthy cells, including blood vessels, immune cells and other 'normal' cells.
In the past, there have been attempts to create 3D images of tissue samples. But the images were low resolution and hence not very detailed, generated after taking photos of slides on a microscope with a camera, one by one, and then assembling them digitally.
But the Leeds University team said that their approach was the first time a standard digital scanner had been used to produce high-resolution images.
CHILDREN CONTROLLED BY MICROCHIP
THE WORST
And now it's in Brazil. The microchip technology that allows schools and parents to know students whereabouts in real time has begun in a college of Vitoria da Conquista, State of Bahia. This outrageous experiment has been already released in several private companies to control their worker and now extended to schools in a worldwide phenomena that threats to become universal. In Victoria, students have to wear shirts which carry a chip that allows monitorization of the frequency of each student and generates the record of the time in real time to parents via SMS. Initially, there will be about 25 000 children and adolescents between 6 and 14 years, haunted with the project. By 2013, it is planned to include all current 42,725 students in the municipal. They can always undress their uniforms, and try a taste freedom.
But soon there will not exist such possibility as this so-called project will evolve to microchips implanted in the body. For the control, was applied to radio frequency identification technology called RFID, developed by a core of Senai and generally adopted by private companies for workers' control. All parents have the phones registered and receive alerts via cell phone on the entry or exit from school. The system does capture through sensors that are installed in the units. They are automatically read the chips and pass the information via text message parents.
