A group of researchers from different countries have developed a new technique of diagnosis of melanoma and other types of skin cancer. The scientists, led by Gorchakov Irene (Irene Georgakoudi) from tufts University (Tufts University), examined under a powerful laser microscope cancer cells and compared them with healthy. Experts have identified the difference between behavior of mitochondria in these cells into cancer if they were located closer to the nucleus of the cell, in healthy was distributed throughout the cell, as the threads of the web. This difference can be seen in the laser microscope, and diagnosis thus, in contrast to a long process of study biopsy only took a few minutes and was error free. However, even if a new technique will be implemented in clinical practice, it will be quite an expensive setup with a laser microscope is worth 100 thousand dollars.
In the UK a six year old boy had a kidney transplant from his mother. At the age of three years James Lewis (James Lewis) fell ill and his condition was so severe that he needed a heart transplant. The donor had to wait 11 months and during this time the kidneys of a child were also badly affected.

The father and mother of the baby passed the desired tests, and it turned out that James’s mom can be a donor. According to her, she didn’t hesitate for a second. So son wasn’t scared, mom came up with the name for the buds and explained to James that Sydney will help him to recover. The transplant was successful, and now the mother and son feel good.

In Canada, scientists genetically modified the mouse, giving it resistance to cocaine addiction. This was done by the staff of the University of British Columbia (University of British Columbia) – they brought animals with a high concentration in the brain protein cadherin. One of its functions is to provide connections between nerve cells. Experts expected that this modification will make the mice more prone to drug due to additional connections in the structure of the brain responsible for rewards. However, things did not go as planned, and is based on experimental individuals preferred to abstain from cocaine use, even having it in free access. Now scientists have set a new goal – to find a molecule that would block the memories about the drug.
