How Many Scientists Fabricate and Falsify Research? A Systematic Review and Meta-Analysis of Survey Data
The frequency with which scientists fabricate and falsify data, or commit other forms of scientific misconduct is a matter of controversy. Many surveys have asked scientists directly whether they have committed or know of a colleague who committed research misconduct, but their results appeared difficult to compare and synthesize. This is the first meta-analysis of these surveys. (PLoS ONE)
What are parents’ rights regarding a child’s medical treatment?
Perhaps no one is watching the Daniel Hauser case in Minnesota more closely than Theresa and Greg Maxin in Ohio. Seven years ago, the Maxins found themselves fighting to keep their own son from having chemotherapy. But the two families’ stories ended quite differently. (CNN)
Stem Cell Breakthrough Could Mute Ethical Debate
A team of experts led by Kim Kwang-soo, head of the Cha Medical Center’s stem cell institute, said they successfully generated induced pluripotent stem (iPS) cells from human fibroblasts, or cells used by the body to synthesize new tissue, by injecting them with a cocktail of “reprogramming” proteins.

Video can help seniors make end-of-life decisions
A new study suggests that elderly patients are able to make more informed decisions about their “end-of-life” care after viewing a video showing a patient with advanced dementia. (CTV.ca)

Louisville close to clinical trials of stem cell treatment for macular degeneration
A UofL researcher is leading the way in a potential cure for macular degeneration. Dr. Henry Kaplan, who routinely treats patients for the disease, says even today 90% of people with age-related macular degeneration really don’t have an effective treatment. So news that researchers at UofL may be close to finding a cure with the help of the patient’s own stem cells is creating a lot of excitement. Although studies in humans aren’t starting just yet, patients may not have long to wait. (WAVE 3 TV)

Draft stem-cell guidelines criticized
As the National Institutes of Health (NIH) begins finalizing guidelines to govern US funding of human embryonic stem-cell research, an initial ripple of researcher worry has swollen into a near-unanimous wave of concern that virtually all existing stem cell lines would be disqualified if the draft guidelines were adopted as written, with their strict informed-consent provisions.
