Science researchers at the University of Pennsylvania conducted a study that may help them reach a better understanding of health conditions such as arteriosclerosis, aneurysms and thrombosis. The results of the study are making the news as one of a number of compelling current science events at the University of Pennsylvania. According to science researchers, blood plasma is thicker and more elastic than water. Depending on how much pressure blood plasma is under, it flows differently under different circumstances, meaning that blood plasma influences how blood flows more concretely than scientists thought in the past.

Oregon State researchers recently discovered DNA in a nematode, a type of roundworm, that may provide an insight into the mechanisms of human aging. The researchers found a specific portion of DNA within the mitochondria of the nematode which displayed the characteristics of "selfish" DNA, in other words, DNA which actually hurts the animal's chances of survival. Scientists have previously found instances of selfish DNA occurring in plants, but this is the first example found in an animal. “We weren’t even looking for this when we found it, and at first we thought it must be a laboratory error,” said Dee Denver, Oregon State associate professor of zoology (photo left courtesy of OSU). "Selfish DNA is not supposed to be found in animals."
The 225th Anniversary of the University of Pittsburgh will be celebrated this year. One of their most notable accomplishments was contributing to the launch of the "Biotech Industry". Herbert Boyer, a Pitt PhD graduate helped discover how to cut and transfer individual genes within the DNA molecule and transfer them from one organism to another. Boyer eventually founded Genetech, widely considered one of the first successful biotech companies.
With many accomplishments, in 2000, Herbert Boyer and his wife established the Herbert W. and Grace Boyer Chair in molecular biology in the University of Pittsburgh’s Department of Biological Sciences. Today the Herbert W. and Grace Boyer Chair in Molecular Biology is used to support an outstanding faculty member in the field of post-genomic molecular biology.
