...Huntington’s disease that might shed light on treatments for similar neurodegenerative diseases. The team—led by scientists at the Harvard-affiliated MassGeneral Institute For Neurodegenerative Disease (MGH-MIND)—identified a novel mechanism of clearing disease-causing mutant huntingtin protein from brain cells by modifying the protein structure for autophagic degradation, a natural degradation process in cells. The introduction of a specific molecular fragment known as an acetyl group into the mutant proteins—a process also known as acetylation—is the key to triggering the destruction of excess huntingtin...
...They fully expected that he would overturn the so-called Mexico City policy restricting family-planning funding overseas, reverse George W. Bush's ban on federal funding for embryonic-stem-cell research and move to rescind a last-minute Bush Administration "conscience clause" rule for medical providers, the latter of which he will probably do as early as next week. But they also presumed Obama would handle and communicate these weighty decisions with a delicate touch, and in that respect, the President has disappointed the crucial voting bloc. It's something Obama can ill afford, especially at time when...
...Embryonic-stem-cell research, for instance, wasn't an issue during the presidential campaign, in large part because John McCain and Obama both support it. Candidate Obama pledged to reverse the ban on stem-cell funding, and his Inaugural Address - in which he vowed to "restore science to its rightful place" - served notice that he would not wait long to do so. So it didn't come as a surprise to Catholics when, on the morning of March 9, the President signed an Executive Order allowing research on embryonic stem cells to go forward after an eight-year halt. Obama...
...reactions of far more moderate Catholics. An editorial in the liberal Catholic magazine Commonweal accused Obama of "obfuscat[ing] the moral dilemma by resorting to imprecise talk about the supposedly self-evident authority of scientific 'facts' and the alleged ideological agenda of those opposed to embryonic-stem-cell research." At the website Beliefnet.com, religion writer David Gibson labeled the decision "Obama's Stem-Cell Flop...
...handling of the Department of Health and Human Services (HHS) rule providing conscience exceptions for health-care workers who for religious reasons refuse to dispense birth control or participate in abortion procedures has upset some Catholics for different reasons. As with the stem-cell decision, Obama's announcement that he would move toward rescinding the rule didn't come as a surprise. In addition, even Catholic leaders disagree about whether federal law provides sufficient protections without the rule, which was one of Bush's last acts in December. If scores of workers would be forced to violate their religious beliefs...
