Scientists Demonstrate Mammalian Regeneration Through a Single Gene Deletion

By |March 17, 2010|Research|

ScienceDaily (Mar. 16, 2010) — A quest that began over a decade ago with a chance observation has reached a milestone: the identification of a gene that may regulate regeneration in mammals. The absence of this single gene, called p21, confers a healing potential in mice long thought to have been lost through evolution and reserved for creatures like flatworms, sponges, and some species of salamander.

In a report published in the Proceedings of the National Academy of Sciences, researchers from The Wistar Institute demonstrate that mice that lack the p21 gene gain the ability to regenerate lost or damaged tissue.

New Evidence Supporting the Effectiveness of Chiropractic Spinal Manipulation for Cervicogenic Headache

The chiropractic Center for Outcomes Studies at Western States Chiropractic College has completed a new study that provides additional support for the use of spinal manipulation in the treatment of cervicogenic headaches. This study adds to a growing body of independent research that supports the efficacy of chiropractic care. The new study compared two doses of therapy as described in the abstract below.

Dr. Mitch Haas and his team at Western States Chiropractic College investigated the differences in dose (8 versus 16 treatments) and between high velocity low amplitude spinal manipulation versus light massage in the treatment of cervicogenic headache. (more…)

We’re so good at medical studies that most of them are wrong

It’s possible to get the mental equivalent of whiplash from the latest medical findings, as risk factors are identified one year and exonerated the next. According to a panel at the American Association for the Advancement of Science, this isn’t a failure of medical research; it’s a failure of statistics, and one that is becoming more common in fields ranging from genomics to astronomy. The problem is that our statistical tools for evaluating the probability of error haven’t kept pace with our own successes, in the form of our ability to obtain massive data sets and perform multiple tests on them. Even given a low tolerance for error, the sheer number of tests performed ensures that some of them will produce erroneous results at random. (more…)
