Researchers have solved the problem of organ transplant rejection

The drug, which was originally intended to be used for the treatment of diabetes but never launched on the market, has found a new life. As The Daily Mail notes, scientists suggest to use it as a remedy for prevention of organ transplant rejection. According to statistics, every sixth patient dies after a heart transplant within a year. And the survivors have the increased risk of infection, weight gain, cancer and diabetes due to the need of using anti-immunity drugs for the rest of their lives.

Stem cells may help to defeat diabetes

Scientists from the University of Copenhagen have found out that stem cells can be successfully converted into beta cells of the pancreas that produce insulin. The transplantation of such cells to diabetics will be a real breakthrough in treatment. According to the researchers, about 415 million people suffer from diabetes in the world, NDTV reports.

New device may slow the growth of brain tumors

Scientists from the US have managed to slow down the growth of glioblastoma (the most aggressive form of brain cancer) by using a new device. This device is attached to the shaved part of the patient's head and generates low-intensity electric fields continuously. A network of isolated electrodes directs the fields to a tumor, reports.

Discovery: genes start mutating soon after conception

According to a new study carried out by scientists of Yale University and the Mayo Clinic, hundreds of small genetic mutations start mutating in the cells of the embryo after conception. Many of these mutations occur in the embryo when sex cells are formed. This means that these mutations can become a part of the genome and be transmitted to the next generation, reports.
