ScienceDaily (2011-06-24) -- Millions of people who have diabetes may soon be free of finger pricks and daily insulin dosing. Researchers are developing an artificial pancreas that will deliver insulin automatically and with an individualized precision never before possible.

To me the time is defined by an increase of entropy and thus pertains to the irreversible processes. In some sense it reflects the transition from reversible state to the irreversible one. In other words the time "kills" the present states of everything surrounding us. Some believe that irreversibility is defined by quantum processes where you can never determine the speed and location of the electron simultaneously which is commonly known as a Geisenberg principle.

ScienceDaily (Aug. 28, 2010) — By creating diseased liver cells from a small sample of human skin, scientists have now shown that stem cells can be used to model a diverse range of inherited disorders. The University of Cambridge researchers' findings, which will hopefully lead to new treatments for those suffering from liver diseases, were published August 25 in The Journal of Clinical Investigation. Because liver cells (hepatocytes) cannot be grown in the laboratory, researching liver disorders is extremely difficult. However, today's new research, which was funded by the Wellcome Trust and the Medical Research Council (MRC), demonstrates how to create diseased liver-like cells from patients suffering from a variety of liver disorders.

A US man is still HIV-free more than three years after receiving a stem cell transplant, suggesting the first cure has been found for the virus that causes AIDS, German doctors say. While the highly lethal technique used on the man known as the "Berlin Patient" would not work for most of the 33 million people with HIV worldwide, scientists say the research shows important progress toward a universal cure. "Our results strongly suggest that cure of HIV has been achieved in this patient," said the study in the peer-reviewed journal Blood, a publication of the American Society of Hematology. The process began in 2006 when a US man in his 40s, who had been HIV positive for more than a decade, sought treatment for acute myeloid leukemia, a lethal blood cancer. After a first round of chemotherapy failed, his German doctor, Gero Hutter, thought he would see if he could perform a bone marrow transplant using a donor with a rare genetic mutation that is naturally resistant to HIV.
