Instrument designed by Armstrong is key part of first spacecraft to land on a comet
Armstrong
A scientific instrument invented by Daniel Armstrong, professor and UT Arlington Robert A. Welch Chemistry Chair, is on board the Rosetta Mission spacecraft’s Philae lander, which successfully landed on a comet 310 million miles from Earth on November 12, news outlets around the world reported.
Armstrong’s chromatography column was put aboard the Philae to analyze samples from the comet for organic molecules. His device separates special molecules, known as the “molecules of life.” Unfortunately, because the Philae had a rougher than anticipated landing on the comet — nicknamed 67P — the lander went dark. Armstrong and others are hopeful that the device will “wake up” again in the early months of 2015, when its solar panels can collect enough sunlight and the comet’s orbit carries it closer to the sun. The lander might then come out of hibernation mode.
In a November 20 interview with KERA radio’s All Things Considered show, Armstrong explained his instrument’s role in the scientific experiments mission leaders hoped to conduct. The instrument is something he designed over 20 years ago.
“We actually developed the column probably late 1990,” Armstrong told KERA. “It was commercialized rapidly and they probably picked it because it was a well-known commercial column that had a long track record and it also had the broadest selectivity — in other words, it seemed to separate the most, the greatest number of compounds and so probably that’s why they picked it.”

Castoe team’s Burmese python research leads to new snake venom evolution model
Todd Castoe, left, with graduate students Jacobo Reyes-Velasco and Drew Schield.
Technology that can map out the genes at work in a snake or lizard’s mouth has, in many cases, changed the way scientists define an animal as venomous. If oral glands show expression of some of the 20 gene families associated with “venom toxins,” that species gets the venomous label.
But, a new study from UT Arlington challenges that practice, while also developing a new model for how snake venoms came to be. The work, which is being published in the journal Molecular Biology and Evolution, is based on a painstaking analysis comparing groups of related genes or “gene families” in tissue from different parts of the Burmese python, or Python molurus bivittatus.
A team led by assistant professor of biology Todd Castoe and including researchers from Colorado and the United Kingdom found similar levels of these so-called toxic gene families in python oral glands and in tissue from the python brain, liver, stomach and several other organs. Scientists say those findings demonstrate much about the functions of venom genes before they evolved into venoms. It also shows that just the expression of genes related to venom toxins in oral glands of snakes and lizards isn’t enough information to close the book on whether something is venomous.

Park team’s research indicates musicians may have advantages in long-term memory
Heekyeong Park
A peek inside the brains of professional musicians has given UT Arlington psychology researchers what may be the first links between music expertise and advantages in long-term memory.
Heekyeong Park, assistant professor of psychology, and graduate student James Schaeffer used electroenceph-alography (EEG) technology to measure electrical activity of neurons in the brains of 14 musicians and 15 non-musicians and noted processing differences in the frontal and parietal lobe responses. The team presented initial results of their new research on November 18 at Neuroscience 2014, the international meeting of the Society for Neuroscience, in Washington, D.C.
“Musically trained people are known to process linguistic materials a split second faster than those without training, and previous research also has shown musicians have advantages in working memory,” Park said. “What we wanted to know is whether there are differences between pictorial and verbal tasks and whether any advantages extend to long-term memory. If proven, those advantages could represent an intervention option to explore for people with cognitive challenges.”

Walsh team’s research findings challenge phenotypic plasticity model in water flea
Matthew Walsh
A new study from UT Arlington biologists examining non-genetic changes in water flea development suggests something human parents have known for years – ensuring a future generation’s success often means sacrifice.
Matthew Walsh, an assistant professor of biology, and his team looked at a phenomenon called “phenotypic plasticity” in the Daphnia abigua, or water flea. Phenotypic plasticity is when an organism changes its trait expressions or physical characteristics, or those of its offspring, because of external factors. In Daphnia, that can mean a generation speeding up its own physical maturation in response to a predator threat or speeding the maturation of its offspring.
Current theory says similar conditions will favor phenotype changes within and across generations of organisms. Walsh’s experiment, which involved about 25 lineages of Daphnia, contradicts that thought.
“The surprising aspect of our research is, they couldn’t do both,” said Walsh, who is lead author on a paper published November in Proceedings of the Royal Society B.

Mohanty team publishes latest findings in optogenetic stimulation, laser beam optics
Mohanty
A UT Arlington physics team is using their expertise in the field of optics and photonics to advance new methods in areas such as mapping the neural circuitry of the brain and guiding neurons to potentially repair damage in the body.
Samarendra Mohanty, an assistant professor of physics, leads the Biophysics and Physiology Lab in the College of Science. He is co-author on two papers published recently. In one published by the online journal PLOS ONE November 10, researchers in Mohanty’s lab described using a method called “two-photon optogenetic stimulation” to carry out in-depth optogenetic stimulation of brain neurons in mouse models – a first in vivo, or in the body, example of the technology.
The second paper was published by Nature Scientific Reports in November and details how scientists used weakly-focused, near infrared laser beams to guide axons to form loops on itself, termed as self-fasciculation, in the lab. Axons are the shafts of neurons, on the tips of which connections are made with other neurons or cells.

Hunt named to peer review panel which will examine EPA Technical Approach Document
Hunt
Andrew Hunt, associate professor of earth and environmental sciences, is one of 12 experts named to serve on a national panel to review the Environmental Protection Agency’s Technical Approach Document, titled Approach for Estimating Exposures and Incremental Health Effects from Lead due to Renovation, Repair, and Painting Activities in Public and Commercial Buildings.
“Before any change in federal regulations, the EPA takes the validation of any approach it uses to evaluate human health exposures very seriously by employing this type of peer review,” Hunt said. “To be on a panel of such experts, that includes a MacArthur ‘Genius Grant’ recipient, is a privilege.”
The expert peer reviewers come from a variety of academic and industrial fields and underwent a rigorous screening process. Candidates were evaluated against the selection criteria described in the Federal Register (Docket ID: EPA-HQ-OPPT-2010-0173-0206).
“This is an important public service and a mark of Dr. Hunt’s esteem in this community,” interim Dean of Science James Grover said.
The panel will convene for a peer-review meeting January 13-14 at the Crystal City in Arlington, Virginia. The meeting will be devoted to discussion and deliberation of issues identified by the peer reviewers regarding EPA’s Technical Approach Document. The meeting is open to the public; those wishing to attend should register here.
Science Week brings alumni, students and faculty together in celebration of science
Evelyn Wang explains her research to the audience during an Open Mic event in the Chemistry & Physics Building lobby held as part of Science Week on November 3.
The College of Science held its annual Science Week celebration the week of November 3-7, bringing alumni, students and faculty together for a series of lectures, Q&A panels and special events.
The main focus of the week is to bring the College’s accomplished alumni back to campus and let them interact with students, who can gain tremendously from hearing about the alums’ experiences. It also gives alumni the chance to see some of the great things today’s students are doing in the classroom and the lab.
“This was our biggest and best Science Week ever,” said Ashley Purgason, assistant dean for undergraduate research and student advancement. “We had a variety of events and had a large number of our wonderful alumni come back to campus to share their expertise and knowledge with our students.”
Events included lectures by alumni and faculty; open mic sessions where students present their research and answer questions from their peers; Q&A panels featuring alumni and professionals in the medical and environmental science fields; a mock Senate hearing with alumni and special guests serving as “senators” while students presented their cases why genetically modified organisms (GMOs) should or should not be regulated; workshops where undergraduates learned about research opportunities and how to apply for them; and a spirit photo contest with prize giveaways.

A team of UT Arlington physics students, led by Nilakshi Veerabathina, assistant professor in practice, entertained and educated K-12 students at the 11th annual Aviation & Transportation Career Expo at DFW International Airport. on October 24.
The Expo, sponsored by DFW Airport, the Federal Aviation Administration, American Airlines and Tarrant County College and held in the American Airlines hangar, brought over 3,300 K-12 students, teachers and administrators from about 60 schools across North Texas together to learn about aviation, transportation and science in general. UT Arlington was one of more than 30 organizations representing the industry, government and academia and has participated in every expo since the event began in 2004.
In the last eleven years UT Arlington has served more than 32,000 K-12 schoolchildren through this event. This year’s team from UT Arlington included physics faculty, staff, and undergraduate physics students and Society of Physics Students (SPS) members.
Physics activities included demonstrations associated with liquid nitrogen; mechanical electrical generators, and microwave oven to create spark discharges and mild shocks; wheels and rotating stools for moment of inertia and gyros; and squeaky magnets to explain electric and magnetic fields. Students and teachers were also presented brochures and other materials from Department of Physics, the College of Science, the UT Arlington Planetarium and University admissions office.

Mydlarz discusses problems facing corals during PUBlic Knowledge talk in Fort Worth
Mydlarz
Laura Mydlarz, associate professor of biology, gave a talk titled “Dead Heat: Can Corals Win the Race Against Rising Temperature and Disease?” on December 2 as part of the PUBlic Knowledge series sponsored by the Fort Worth Museum of Science and History.
Mydlarz’s talk, held at the Live Oak Music Hall in Fort Worth, focused on corals and the problems they face from disease and rising ocean temperatures. A Q&A session followed her presentation.
Rising ocean temperatures in the Caribbean and elsewhere have negatively affected the algae which many corals depend on for essential nutrients by photosynthesis, particularly carbon. The algae also give color to the corals and without the algae, many Caribbean corals have turned white, a phenomenon called coral bleaching. Making the situation worse, a variety of diseases have affected already-weakened corals, killing many. The loss of coral reefs threatens ocean biodiversity worldwide.

Weilmuenster quoted in Morning News story on tougher math standards in Texas schools
Weilmuenster
Jacqueline Weilmuenster, a master teacher of mathematics in UT Arlington’s UTeach program, was quoted in a Dallas Morning News story on November 15 about frustrations with implementation of new statewide K-12 math standards.
“Teachers are finding it difficult to do two or three years of instruction without leaving students behind. Many tell me they're spending a few days on topics they've previously spent weeks to develop,” Weilmuenster said.
The state of Texas approved new standards in math curriculum in 2012 and the standards went into effect this fall. The reviews are mixed so far, the story says, but many teachers, administrators and parents are raising concerns that the new guidelines are leaving too many students behind. Members of the State Board of Education say they are open to suggestions for ways to improve the system.
