College of Science graduates were all smiles during the Spring 2013 commencement ceremony.
The College of Science gained around 400 new alumni with the graduation of the Class of 2013 on May 11.
The Spring 2013 commencement ceremony, held in College Park Center, gave families and friends the chance to see their graduates cross the stage and be recognized for their years of hard work and sacrifice.
The ceremony, which included graduates from the College of Science and the School of Architecture, began with a welcome from Provost Ron Elsenbaumer, and introduction of the stage party by Dean of Architecture Donald Gatzke. Dean of Science Pamela Jansma then greeted the audience and introduced the guest speaker, COS alumnus Scott Green (Biology '99), who founded The Greenery, a full-service nursery in Waxahachie, in 1987. Wanting to expand his knowledge base and credibility in his business, Green went back to school and earned a B.S. in Biology, with an emphasis in Botany, from UT Arlington in 1999.
"I want to congratulate all of you graduates here tonight," Green said. "Fifty-two percent of you are first-time college graduates in your families, as I was. The time, effort and sacrifices have paid off."
Green encouraged the graduates to pursue their dreams with passion, and asked them to always remember to lend a hand to those less fortunate than themselves.
"Use that same dogged determination that got you here to make a difference in the lives of others," he said.

Morton wraps up 30-year career as assistant dean for student affairs, pre-med advisor
Morton
Edward Morton, assistant dean for student affairs and health professions advisor, retires from UT Arlington June 1 after 30 years with the College of Science.
Morton, who has helped thousands of students get and stay on track to go to medical school, is stepping down and plans to enjoy retirement "while I'm still able to," he joked.
"Ed's tireless dedication to the College of Science has been instrumental in the success of our students and our programs for three decades," Dean Pamela Jansma said. "He has been an advocate for the student, always looking for ways to strengthen advising and teaching within the college, while maintaining high standards. He has advised thousands of our undergraduates as they pursued the options before them for careers and graduate study. His commitment ensured that our students received the best preparation for entry into the professional programs in health professions. His compassion, empathy, and willingness to listen resulted in many undergraduates finishing their degrees who may otherwise not have been able to do so."
Morton has served in a wide variety of roles in his 30 years at UT Arlington. Some of his duties have included pre-med curriculum coordinator; chair of the college's Grade Appeals Committee; coordinating academic advising for all six COS departments; handling health professions scholarships, including selection of recipients; approving all of the college's degree plans; editing the college's undergraduate course catalog; and directing the University's Joint Admission Medical Program (JAMP), which provides services and support for economically disadvantaged students who wish to pursue a medical education. Most recently, he spearheaded the creation of the college's new Advising Center, which centralizes the advising process for COS students.
Morton says he will miss interacting with colleagues and helping guide students toward their goal of a medical career, but says now that he has made the decision to retire, he has no regrets.
"I think it's time to let someone younger come in and do this job," he said. "It's been a great experience working here, but I think 30 years is enough. The people are what have made this job so wonderful, and I'll miss them. I'm excited to see what great things the college and UT Arlington will do in the future."

MacDonnell finds new ruthenium complexes that could control cancer cell growth better
MacDonnell
A team of UT Arlington researchers has identified two ruthenium-based complexes they believe could pave the way for treatments that control cancer cell growth more effectively and are less toxic for patients than current chemotherapies.
Fred MacDonnell, professor of chemistry and biochemistry, has been researching a new generation of metal-based antitumor agents along with a team from the City of Hope Comprehensive Cancer Center in Duarte, Calif. Their aim is to find new therapies to complement widely used platinum-based therapies, such as cisplatin. Cisplatin is one of the most widely used anti-cancer drugs and shows remarkable effectiveness against some cancers, however it does not work on all cancers and can have severe side effects.
In a study published in the May edition of Molecular Cancer Therapeutics, the team describes two newly developed ruthenium polypyridyl complexes, or RPCs, that yielded results comparable to cisplatin against human non-small cell lung cancer cells in pre-clinical lab tests.

Gough co-authors Nature paper on effects
of rising temperatures in Alaskan tundra
Gough
A recent paper in the journal Nature that is co-authored by UT Arlington associate professor of biology Laura Gough is challenging long-held ideas about the effects of temperature increases in the Alaskan tundra.
High latitudes contain nearly half of global soil carbon, and scientists have been concerned that warming temperatures could lead to increased microbial activity and more of that carbon being released into the atmosphere as carbon dioxide. Increased carbon dioxide releases would then speed warming even more, enhancing the greenhouse effect.
Instead, the research team working at the U.S. Arctic Long Term Ecological Research Site in northern Alaska found that carbon stocks in soils subjected to 20 years of experimental warming did not differ from soils that experienced ambient air temperatures. Gough and her co-authors believe a complicated interplay between increased woody-shrub growth and the soil could be counteracting the warming effects.

Mohanty's new fiber-optic, optogenetic stimulator has potential for brain mapping
Mohanty
A new tool being developed by Samarendra Mohanty, UT Arlington assistant professor of physics, could help scientists map and track the interactions between neurons inside different areas of the brain.
The journal Optics Letters recently published a paper by Mohanty on the development of a fiber-optic, two-photon, optogenetic stimulator and its use on human cells in a laboratory. The tiny tool builds on Mohanty's previous discovery that near-infrared light can be used to stimulate a light-sensitive protein introduced into living cells and neurons in the brain. This new method could show how different parts of the brain react when a linked area is stimulated.
The technology would be useful in the BRAIN mapping initiative recently championed by President Barack Obama, Mohanty said. BRAIN stands for Brain Research Through Advancing Innovative Neurotechnologies and will include $100 million in government investments in research.

Castoe, Fujita contribute to project which mapped genome of western painted turtle
Castoe Fujita
Matthew Fujita and Todd Castoe, assistant professors of biology, have recently completed work on an international effort to sequence the genome of a western painted turtle, only the second reptile species to have its genetic information fully mapped.
Castoe and Fujita, both of whom joined the UT Arlington College of Science in 2012, were among 30 co-authors on a recent Genome Biology publication that described the work. Researchers found that some of the western painted turtle's extraordinary abilities - like being able to withstand oxygen deprivation and near total freezing of its tissue may be linked to sets of genes that are common to all vertebrates, but used uniquely in the turtle. It also showed that the turtle genome has evolved extremely slowly.
Learning more about how common gene networks work in different vertebrates such as the turtle could someday lead to better understanding of human disease, scientists say. The scientists also looked to the genome for information about the turtle's lack of teeth, as well as its immune function, longevity and determination of whether offspring are male or female.

Yousufuddin contributes to journal article about transition-metal-free direct arylation
Muhammed Yousufuddin works with the newly upgraded SMART APEX II single crystal diffractometer, which he used to perform analyses for the study.
Muhammed Yousufuddin, research scientist in chemistry and manager of the UT Arlington Center for Nanostructured Materials, is co-author of a study which is the cover story in the May 15 edition of the Journal of the American Chemical Society about collaborative research in biaryls.
Yousufuddin collaborated with Hongyin Gao and László Kürti of UT Southwestern Medical Center in Dallas, and Daniel H. Ess of Brigham Young University.
Biaryls, where two aromatic rings are connected by a covalent bond, are a common structure in pharmaceuticals, organic materials, and ligands for catalysts. Such molecules are typically made by connecting functionalized, and often activated, aromatic rings using a transition metal catalyst.
The team developed an arylaryl coupling reaction that does not require a transition metal catalyst. The reaction forms a 2-amino-2′-hydroxy-1,1′-biaryl or a 1-amino-1′-hydroxy-4,4′-biaryl, depending on the reaction mechanism. The products were confirmed using crystal structure analysis performed by Yousufuddin.
A news article about the work will appear in an upcoming edition of Chemical and Engineering News. Read the JACS article here.
Dasgupta, students publish online article on status of detection in ion chromatography
Dasgupta
Purnendu 'Sandy' Dasgupta, the Jenkins Garrett professor of chemistry and biochemistry, recently co-authored an article in Chromatography Online about the status of detection in ion chromatography.
Dasgupta, one of the world's leading experts in the field of ion chromatography, co-authored the article with Hongzhu Liao and C. Phillip Shelor, both graduate students in his lab.
The article focuses on the most popular detectors in ion chromatography: the conductivity detector and the charge detector. The article also discusses conductivity detection, including the capacitively coupled contactless conductivity detection. Charge detectors developed in Dasgupta's laboratory are shown to complement conductivity detectors.

Mattioli encouraged by early results of COCOnet natural hazard detection project
Mattioli
Glen Mattioli, professor of earth and environmental science, is mentioned in an article in Nature about COCOnet, the network of sensors designed to monitor and track natural hazards in the Caribbean
Mattioli is on leave from UT Arlington while serving as a program director at UNAVCO, a geodetic-survey organization based in Boulder, Colorado, that is managing the COCOnet project.
The article discusses how COCOnet (Continuously Operating Caribbean GPS Observational Network) is helping geophysicists detect the crustal strains and brewing storms that threaten the region.
Early results from the $6 million system, funded by the U.S. National Science Foundation, were presented in Cancún, Mexico, on May 17 at the American Geophysical Union Meeting of the Americas. In the article, Mattioli talks about the difficulties in setting up the sensors while dealing with 31 separate national governments, many of which distrust the United States. The project has made more progress than expected in acquiring the permits needed to set up stations, Mattioli said — even in Cuba.
COCONet stations are being set up at sites as diverse as steep rainforest slopes and isolated coral-reef islands, the article says. Each station contains meteorological instruments, along with a GPS unit that constantly monitors ground movements and, in many cases, transmits those data in near real time. So far, UNAVCO has built or upgraded 38 of its planned 69 sites. At least 61 existing stations are also being incorporated into the network.
