...more than cash. The President's approval numbers are still low, but in an age of micro-targeting, he can help shore up some wavering constituencies. To the extent McCain has trouble turning out the conservative base that still doesn't trust him on sanctity of life issues like stem cell research, Bush may be able to help. He may also prove useful in mobilizing some otherwise despondent conservatives who care particularly about judicial appointments and the courts. "One of the most important things Bush will be remembered for is the fact that he put two justices on the Supreme...
...study Researchers at the biotech firm Novocell report the first successful use of human embryonic stem cells (HESCs) in treating a disease--diabetes--in mice. After generating HESCs from excess fertility-clinic embryos, the scientists cultured the cells for 12 days in a medium that directed them to become pancreatic cells. These were transplanted into mice whose own pancreatic cells had been deliberately destroyed, making them insulin-deficient. Within 45 days, new cells began producing fresh insulin...
What this means for us It's just a first step. In humans with Type 1 diabetes, the body destroys pancreatic cells, so the stem cells might be attacked the same way. The HESCs also produced tumors in the mice, making the method too dangerous...
Researchers from the Harvard Stem Cell Institute (HSCI) and Mass. General Hospital (MGH) are one step closer to reprogramming adult stem cells and making them capable of creating tissues for all parts of the body without the use of viruses or cancer-causing genes. Harvard Medical School professor Konrad A. Hochedlinger recently discovered how long adult mouse stem cells need to be exposed to reprogramming factors before they convert to a pluripotent, embryonic-like state, at which point they can be potentially used for medical treatments. According to Hochedlinger, his lab set out to unveil the mysteries of the reprogramming...
...scholastic aptitude and demonstrated potential to achieve great things. He was one of the most well rounded people we have ever met. He excelled in athletics, academics, music, research, and making friends. He was training to run the Boston Marathon while managing an impressive course load, conducting stem cell research, and learning to play the guitar. Based upon such stellar performance and his friendly demeanor, who would have ever guessed that something was terribly wrong...
