Scientists develop cancer-killing stem cells in lab. Researchers have developed a breakthrough method of turning stem cells into attackers to target and fight brain tumors. The newly designed way introduces stem cells engineered to produce toxins which are able to kill brain tumors, without succumbing to their effects. As a stem-cell-based therapy for cancer, the newly-developed method does not threaten... 

In a significant breakthrough, scientists have found a cheap and easy way to produce highly sought-after embryonic-like stem cells without terminating any embryos. The ground-breaking discovery could usher in a new era in stem cell biology. Although the research was carried out on laboratory mice, scientists believe that the same approach should also work on human cells, researchers said. “If...
