With the genetics of so many organisms that have different traits yet to study, and with the techniques for gathering full sets of genetic information from organisms rapidly evolving, the “forest” of evolution can be easily lost to the “trees”…
Brain aneurysms, in which an artery wall balloons out abnormally, can lead to death or disability. Inserting small metal coils into burst aneurysms can decrease by 25 percent the risk of patient death and disability during the first year after the procedure, according to preliminary results of a long-term study published in the The Lancet. The coils are like “miniature slinkies that are folded gently into the aneurysm like a ball of yarn one by one to stop the bleeding,” said one of the researchers, noting that the procedure also can be used to prevent aneurysms from bursting. “With coiling, we can either help fix the damage or prevent it from occurring.” Surgical clipping is currently the most common method of treating brain aneurysms.
