We are still many thresholds away from anything that can be of practical value to me and others. Scientifically, it makes no sense to abandon any promising avenue just because another has opened...
...method adopted before is the easiest way of getting statistics, but the current method is better,” Halperin said...
...method the researchers in Japan and Wisconsin used to arrive at stem cells involves transferring four genes into the genome of a mature cell through virus. These four genes produce factors that “reprogram” the mature cell’s genome to a stem-like state. No viable embryo, therefore, is either created or destroyed—which is the main qualm of conservative opponents of the research...
This year’s report uses national household surveys, which are believed to be more representative of the prevalence of HIV. Under the new method, the number of HIV victims in India dropped by more than half, to 2.5 million...
