But for natural resource professionals, "wild parsnip"means an invasive plant that can cause blisters on arms or legs while they work outdoors. Scientists Track 'Stealth' DNA Elements In Primate Evolution
Louisiana State University scientists have demonstrated that specific DNA sequences play a crucial role in human evolution by surreptitiously spawning hyperactive progeny copies. These "stealth driver"elements have given rise to the most abundant family of DNA elements in the human genome: Alu elements. The study, which was led by LSU scientist Dr. Mark A. Batzer, provides the first strong mechanistic evidence for the evolution of Alu elements to date. Top 10 Unanswered Questions in Geeky Movies
GeekDad’s list of the ten best unanswered questions from geeky movies. What do we mean by 'best?' Well, these are ones that are fun to talk about, but that aren’t so significant as to seriously detract from the movie’s quality.

A classic explanation for oceanic hot spots such as Hawaii has been that they originate from upwellings of hot rock, called mantle "plumes," deep in the Earth's mantle. Evidence for these deep structures has been sketchy, however. Now, a sophisticated array of seismometers deployed on the sea floor around Hawaii has provided the first high-resolution seismic images of a mantle plume extending to depths of at least 1,500 kilometers (932 miles).

Although most patients don't know it, 21 US states follow some form of an 1880 ruling that says the standard of care physicians must meet by law depends on where the doctor practices, even if, in some cases, it is a small town with only two doctors. That means what is considered malpractice in some states may be considered acceptable practice in others. Driving Abilities Not Impaired By Moderate, Long-Term Pain Medication
Opioid pain relievers, such as morphine and other narcotics, carry warning labels urging patients not to drive or operate heavy machinery during use. In addition, drivers under the influence of pain medication are typically subjected to the same laws and penalties as drivers under the influence of alcohol. And yet, in a recent, preliminary study researchers found no difference in the "driving skills and reaction times"of patients taking morphine compared to non-medicated drivers. Mystery Blood Vessel Disorder Implicated In 'Mini' Strokes
Physicians have long been puzzled by a condition called intracranial arterial dolichoectasia, in which the larger arteries of the brain become elongated and misshapen. There is recent evidence that people with dolichoectasia are more likely to have aortic aneurysms, a potentially fatal weakening of the main artery that carries blood out from the heart.
