Scientists Make Mice Transparent

Scientists have made mice transparent - let us hope they were dead first! Studying the human body and test animals in general is difficult because usually one has to carry out dissections to see inside.  The new process will change medicine. Lipids block sunlight in bodies, so it has to be replaced with acrylamide which is just transparent hydrogel. After the acrylamide is absorbed, the bodies are placed into detergent which absorbs the lipids. Electricity is also applied to reduce the time taken to "clean" tissue. The treated mice do not keep their original shape. They end up like gel in a plastic bag. Internal organs can be clearly seen, however. After staining, the structure of organs can be seen as shown in the picture above. Micro-slicing has been used to date. A computer assembles a 3D structure for study. Both systems will probably be used in future as each as its benefits. There are plans to adapt the transparency technique to evaluate tissue in c

Imaging More Advanced Than MRI

The MRI was the most advanced way of diagnosing what patients were suffering from. It was cutting edge technology that gave very detailed images of the human body. Technology moves forward and advances are made. Macquarie University with CSIC and the Institute of Photonic Sciences (ICFO) have found a way of producing images even clearer than MRI. It is done by using artificial atoms and nitrogen doped diamond nanoparticles. Extremely weak magnetic fields in the human body can now be detected. MRI resolution is millimetric. The new system "sees" down to a millionth of a millimeter. This technique is not invasive. It will provide an understanding of intracellular processes. The problem with the new diagnostic system is that very temperatures are required to make it work. Artificial atoms are encapsulated in a diamond crystal. They can be manipulated by lasers, dragging atoms above the surface for medical diagnosis. http://www.adventure--australia.blogspot.com/ http:
