| School test scores mixed for NE La. - News-Star Posted: 03 Oct 2009 08:05 AM PDT End of Course test scores released by the state Department of Education this week are a mixed bag for school districts across northeastern Louisiana. While Ouachita and West Carroll parishes are among the districts with the largest percentages of students scoring "excellent" in English II, Tensas, Madison and Union are among the worst scores in the state for Algebra I. The tests, which will eventually replace the Graduate Exit Exam as a graduation requirement, are not considered high stakes tests at this point. The test classifies student scores into the following four categories: Excellent students have demonstrated a mastery of the course content beyond "good;" Good students have demonstrated mastery and are well prepared for the next level, "fair;" Fair the student has only the fundamental knowledge and skills needed for the next level; Needs improvement the student has not demonstrated the fundamental knowledge and skills necessary for the next level. The state Department of Education said when the end of course subject tests are in place for graduation, the "needs improvement" category will likely mean the student has failed. In Tensas Parish, 63 percent of students scored in the "needs improvement" category in Algebra I. Sixty percent of students in Union and Madison also scored in the bottom category. In English II, 49 percent of Madison students scored "needs improvement." Sixty-nine percent of students in West Carroll Parish tested either excellent or good in English II, while 66 percent of Ouachita students ranked in the top two categories. End of course testing was recommended by the High School Redesign Commission to ensure consistent and rigorous instruction and academic expectations throughout Louisiana high schools. Monroe City Schools Instructional Support Supervisor Tammye Turpin said the new tests are a better gauge of student proficiency than the Graduate Exit Exam. "They are content specific for each course," Turpin said. "The End of Course test concentrates on the grade level expectations for that specific course." | |
| 'Promiscuous' Protein Interactions Found In The Nuclear Pore Complex - Science Daily Posted: 03 Oct 2009 08:13 AM PDT ScienceDaily (Oct. 3, 2009) — In higher organisms, cells are very selective about what passes in and out of their nuclei, where the genes reside. This selectivity helps protect the DNA and is the job of machines that stud the envelope of the nucleus, called nuclear pore complexes. These gatekeepers have proved largely inscrutable to researchers over the years, despite their conspicuously large size (they are made of 30 different proteins, or nucleoporins), but bit by bit, scientists are learning how these machines work. Now a new study reveals the molecular structure of the largest piece of the molecule-trafficking complex to be captured by x-ray crystallography to date. Researchers have also shown that one member of the three-protein structure interacts promiscuously with two nucleoporins as do other proteins in the nuclear pore, supporting a model of a flexible complex that can rearrange itself into different formations. The work suggests an important design feature of this transport organelle, an ancient evolutionary innovation fundamental to the development of multicellular life on Earth. The research, performed by Vivien Nagy, a visiting graduate student, André Hoelz, a research associate, and colleagues in Rockefeller University's Laboratory of Cell Biology, uncovered the molecular structure of three interacting proteins that form the centerpiece of the Nup84 complex — an important structural component of the nuclear pore complex. The Nup84 complex is a Y-shaped heptamer — a molecule composed of seven units — that was recently imaged in three dimensions by Martin Kampmann, also a member of the lab headed by Günter Blobel, John D. Rockefeller Jr. Professor and an investigator at the Howard Hughes Medical Institute. In experiments to be published online in the Proceedings of the National Academy of Sciences, in September Nagy, Hoelz and colleagues provide the molecular specifics of the only piece of the Nup84 complex that remained unknown, furthering the structural characterization of this building module. They also describe competing interactions within the Nup84 complex and discuss the possibility of binding promiscuity as a common feature in the nuclear pore complex. These findings suggest that more than one assemblage of its elements may be necessary for the function of the nuclear pore complex — to import and export macromolecules including ribosomes and messenger RNA. "Now that we realize that promiscuity may be a major factor in the nuclear pore complex — that the nucleoporins have different ways of interacting with each other — the complex is no longer just a three-dimensional jigsaw puzzle," Hoelz says. "Now we have to place these structures into a fourth dimension and find out when they adopt these different shapes. We're trying to take snapshots, static pictures, and turn them into a movie. It will require a lot more pictures, a lot more structures, before we understand the function and dynamics of this intricate transport organelle. | |

| National Geographic star speaks to Hartnell College students - Thecalifornian.com Posted: 03 Oct 2009 04:52 AM PDT Just four days ago, National Geographic explorer Mireya Mayor was deep in the forests of Congo, studying gorillas. Then she flew across the globe to describe the surprising path she took from NFL cheerleader to jungle explorer in a Friday speech at Hartnell College. Mayor always loved animals but said teachers discouraged her from studying science because she struggled in math and chemistry. Instead, she studied English and philosophy, and was even a Miami Dolphins cheerleader. In her junior year, she took an anthropology course that changed her path. She resolved to travel to Madagascar and South America to study lemurs, small nocturnal primates that live deep in the rainforest. Once she was there, a National Geographic documentary team looking for a lemur researcher asked her if she'd like to join its project. She agreed, then translated that first experience into to regular gigs leading expeditions for both the History Channel and the National Geographic Channel. On her adventures she swam with man-eating sharks, nursed leopards back to health and went days without food to find an elusive endangered species. She's also raised awareness of logging and poaching in Madagascar. The leopards suffered from hydrocephalus, or fluid on the brain. She had found them unable to walk properly. In a hospital, a treatment with vitamin B-12 proved helpful, and could turn out to have human applications, Mayor said. She was the second of four speakers this season for the Science, Technology, Engineering, and Mathematics Colloquium sponsored by Women in Science and Engineering. About 50 students, professors, and community members attended. Silvia Cooke, a biology and neuroscience teacher at Salinas High School, had never seen Mayor's show, but was drawn in by the flier. "I saw her picture with the tiger and thought, 'I have to see this,' " Cooke said. Hannelore Rose, a first-year science student at Hartnell, said she had seen Mayor before on the National Geographic Channel. "It's one of the few shows that capture my undivided attention." |
