Courtesy of VSU Courtesy of VSU News Release: Valdosta State University VALDOSTA Dr. Joshua Reece, assistant professor of biology, received the Best Presentation Award during the 37th Annual Herpetology Conference, hosted by the University of Florida in Gainesville, Fla. April 4-5. Reece was one of 16 presenters - whose talks included topics that covered all aspects of herpetology, or the study of amphibians and reptiles, including natural history, ecology, evolution and physiology. My presentation covered how loggerhead turtles in Florida and Georgia are affected by humans building on our coasts, said Reece. The presentation included contributions from VSU undergraduates Qiana Sweet and Brianna Shepherd both freshman biology students. The talk highlighted Reeces research on climate change and its effects on sea turtles. According to the study on the loggerhead turtles, placement of this nesting places have shifted northward over the course of 20 years. This move has been a shift away from coastal development most likely in response to warming temperatures toward areas of increased erosion. The study found a decrease in the width of beaches by more than 10 feet from 1986 to 2006, with models projecting a 43 percent loss in beach area by the year 2060. The … Continue reading →

Vacant positions within Brandon Universitys department of biology are affecting its ability to offer courses popular with students, according to department chair Bill Paton. Two positions currently vacant within the universitys biology department include an associate professor position and a physiology professor position. Although the university is currently seeking a new associate professor, theres no word yet on whether the physiology professor will be replaced, Paton said. Budgetary restraints as well as a bigger focus on offering the courses students require for graduation could be why administration has yet to hire a replacement, Paton said. If you cut courses, then students cant get the selection of courses that they would like and they go elsewhere, he said. For Brandon University to compete, we have to be attracting students from other parts of Manitoba, including Winnipeg. Although physiology courses are popular with students, they arent required for graduation, he said, adding the two vacancies have also forced professors to step in to help offer the required courses. Along with physiology courses, an advanced human ecology course was also cancelled this year due to a lack of staff, he said. Its a high-demand course, clearly by students in the pre-medical major, and … Continue reading →

A long-standing challenge in synthetic biology has been to create gene circuits that behave in predictable and robust ways. Mathematical modeling experts from the University of Houston (UH) collaborated with experimental biologists at Rice University to create a synthetic genetic clock that keeps accurate time across a range of temperatures. The findings were published in a recent issue of the Proceedings of the National Academy of Sciences. "Synthetic gene circuits are often fragile, and environmental changes frequently alter their behavior," said Kresimir Josic, professor of mathematics in UH's College of Natural Sciences and Mathematics. "Our work focused on engineering a gene circuit not affected by temperature change." Synthetic biology is a field in which naturally occurring biological systems are redesigned for various purposes, such as producing biofuel. The UH and Rice research targeted the bacterium E. coli. "In E. coli and other bacteria, if you increase the temperature by about 10 degrees the rate of biochemical reactions will double - and therefore genetic clocks will speed up," Josic said. "We wanted to create a synthetic gene clock that compensates for this increase in tempo and keeps accurate time, regardless of temperature." The UH team, led by Josic and William Ott, … Continue reading →

You dont get very far discussing synthetic biology and biohacking before someone asks about bioterrorism. So, lets meet the monster head-on. I wont downplay the possibility of a bioterror attack. Its already happened. TheAnthrax-contaminated lettersthat were sent to political figures just after 9/11 were certainly an instance of bioterrorism. Fortunately (for everyone but the victims), they only resulted in five deaths, not thousands. Since then, there have been a few copycat crimes, though using a harmless white powder rather than Anthrax spores. While I see bioterror in the future as a certainty, I dont believe it will come from a hackerspace. The 2001 attacks are instructive: the spores were traced to a U.S. biodefense laboratory. Whether or not you believe Bruce Ivins, the lead suspect, was guilty, its clear that the Anthrax spores were developed by professionals and could not have been developed outside of a professional setting. Thats what I expect for future attacks: the biological materials, whether spores, viruses, or bacteria, will come from a research laboratory, produced with government funding. Whether theyre stolen from a U.S. lab or produced overseas: take your pick. They wont come from the hackerspace down the street. Breeding superbugs sounds trivial in … Continue reading →

Candi Roy, left, talks with Galina Abdelaziz, 16, a junior, in the Biology III class during a lesson about heart rate at Vanguard High School in Ocala on Monday. Two dozen students in Candi Roy's Biology III class checked heart rates Monday the old-fashioned ways: fingers on wrist, stethoscope, or both. Last fall, the National Science Teachers Association announced the 2014 Shell Science Lab Challenge. Hundreds of schools from the United States and Canada submitted applications in hopes of getting $20,000 in new lab equipment. On Friday, Vanguard High teacher Candi Roy was presented the grand prize trophy and $20,000 to transform her classroom into a state-of-the-art lab. Grand prize Vanguard High School Candace Roy, International Baccalaureate biology teacher Finalists Northeast High School, Philadelphia eStem Public Charter School, Little Rock, Ark. Taos Middle School, Taos, N.M. Delta High School, Delta, Colo. This lab assignment, part of the human anatomy and physiology chapter, required the students to compare the pulse before and after some type of physical exertion. Students were given several activities to endure, everything from running up and down steps to changing seats. Next year, students in this biology class will have a much easier time trying to register … Continue reading →
