University of Maine News - Thu, 02/13/2014 - 13:08

The Geddes W. Simpson Lecture Series Fund was established in the University of Maine Foundation in 2001 by the family of Geddes Wilson Simpson, a well-respected faculty member who began his 55-year career with the College of Life Sciences and the Maine Agricultural Experiment Station in 1931. Simpson was named chair of the Entomology Department in 1954 and remained in that position until his retirement in 1974. Upon his retirement, he was awarded emeritus status and thereafter worked part time with the Experiment Station as editor.

The Geddes W. Simpson Distinguished Lecture was established to support a lecture series through which speakers of prominence “who have provided significant insight into the area where science and history intersect” are invited to speak on campus. Any field that bridges these two areas of inquiry is welcome, and in the past the series has hosted a broad range of speakers from various academic disciplines. The 2014 lecture will be the 13th in the series.

Learning Across STEM Disciplines

University of Maine News - Thu, 02/13/2014 - 12:27

UMaine researchers seek to improve the teaching of thermodynamics and electronics in physics and engineering.

Researchers at the University of Maine hope to improve the teaching and learning of two central topics in physics and engineering that are critical to undergraduate programs through a three-year project.

John Thompson, an associate professor of physics and cooperating associate professor of STEM education, and MacKenzie Stetzer, assistant professor of physics and cooperating assistant professor of STEM education, have received $599,999 from the National Science Foundation to investigate student learning of thermodynamics and electronics — including electric circuits — in both disciplines.

“Only in the last 10 years or so have researchers really targeted student learning beyond the introductory level, including in laboratory settings.  Interdisciplinary research that focuses on specific physics and engineering content is also relatively novel,” says Thompson of the project.

Both of the targeted areas are aligned with a recent National Research Council report on the status and future directions of discipline-based education research, Stetzer adds.

Undergraduate programs in physics and engineering often include parallel courses that teach the same topics, so the researchers want to determine the important differences between what students do and don’t learn in courses that cover the same material.

Thompson and Stetzer have previously conducted research on learning in STEM fields. Their research — along with studies conducted by many other researchers — confirm that if a student can correctly solve textbook problems, it doesn’t always mean they understand the underlying concepts.

The researchers plan to look at content in parallel courses across disciplines for similarities and differences; study student conceptual understanding across disciplines before and after instruction through written questions, interviews and classroom observations; and use research results to guide the modification and testing of existing instructional materials as well as the development of new materials for use across disciplines to help students learn difficult material in physics and engineering courses.

“Figuring out what works across disciplines and leveraging the strengths of effective instructional strategies employed in both disciplines are ways to increase the efficiency of these typically rather time-consuming research-based curriculum development efforts,” Stetzer says.

Physics Ph.D. students Jessica Clark and Kevin Van De Bogart are leading the work in thermodynamics and electronics, respectively; the research will be the focus of their dissertations. Donald Mountcastle, associate professor of physics and cooperating associate professor of biochemistry, and Wilhelm Alexander Friess, associate professor of mechanical engineering and director of UMaine’s Brunswick Engineering Program are the project’s senior personnel. The research is taking place in courses in mechanical, chemical, and electrical engineering, as well as in physics.

The majority of the project’s research staff are members of UMaine’s Physics Education Research Laboratory (PERL) and the Maine Center for Research in STEM Education (RiSE Center). The PERL consists of about 15 faculty, postdoctoral and graduate students in physics and science education. The RiSE Center includes faculty from several STEM departments and houses programs for a master of science in teaching and a Ph.D. in STEM education.

The researchers say due to the project’s interdisciplinary nature, it has the potential to improve the teaching and learning of physics and engineering at not only UMaine, but beyond, including internationally.

“The development of effective instructional materials based on research is particularly challenging. While many individual faculty develop their own materials and strategies, they usually don’t have time to thoroughly research how well that all works and iteratively refine the materials,” says Thompson, who is also co-director of the PERL.

The modified materials created from the project will be designed to be easily integrated into existing courses and won’t require instructors to implement an entirely new curriculum.

“Coming from a physics perspective, we’ve already begun to see reasoning approaches in engineering classes that we hadn’t observed when working with physics students,” Stetzer says. “We expect to see a similar phenomenon as we collaborate more fully with our engineering colleagues in the project and begin to ask engineering-based questions in physics courses.”

The findings are expected to positively affect all disciplines engaged in teaching thermodynamics and electronics, and could lead to the development of a more coherent educational experience, especially for undergraduates in physics and engineering, the project proposal states. The documentation of differences in instructional approaches and learning outcomes could become a valuable resource for instructors, textbook authors, curriculum developers, education researchers and governing bodies in both disciplines.

“Our findings on student difficulties and the effectiveness of different instructional approaches should inform more nuanced studies within each discipline. This will in turn produce new results that can improve the learning and teaching of these topics more broadly,” Thompson says.

Pooling Expertise

University of Maine News - Thu, 02/13/2014 - 12:25

University of Maine researchers have designed a handheld device that can quickly detect disease-causing and toxin-producing pathogens, including algal species that can cause paralytic shellfish poisoning.

The device — a colorimeter — could be instrumental in monitoring coastal water in real-time, thereby preventing human deaths and beach closures, says lead researcher Janice Duy, a recent graduate of UMaine’s Graduate School of Biomedical Science and Engineering. Duy is now conducting postdoctoral research at Fort Detrick in Maryland.

The research team, which includes UMaine professors Rosemary Smith, Scott Collins and Laurie Connell, built a prototype two-wavelength colorimeter using primarily off-the-shelf commercial parts. The water-resistant apparatus produces results comparable to those obtained with an expensive bench-top spectrophotometer that requires technical expertise to operate, says the research team.

The instrument’s ease of use, low cost and portability are significant, say the researchers. The prototype cost researchers about $200 to build; a top-shelf spectrophotometer can cost about $10,000.

A touch screen prompts users at each step of the protocol. Researchers say an Android app is being developed to enable future smartphone integration of the measurement system.

Duy says the device almost instantaneously identifies pathogenic organisms by capturing target RNA with synthetic probe molecules called peptide nucleic acids (PNAs). A cyanine dye is added to visualize the presence of probe-target complexes, which show up as a purple solution; solutions without the target RNA are blue.

The versatile instrument can also be adapted to detect other organisms. The researchers say, in theory, any organism that contains nucleic acids could be detected with the simple colorimetric test. They have verified the system works with RNA from a soil-borne fungus that infects potatoes.

The research team’s teaching and expertise spans several UMaine schools and departments, including Electrical and Computer Engineering Department, the Laboratory for Surface Science and Technology, the Graduate School of Biomedical Science and Engineering, the Department of Chemistry, the School of Marine Sciences and the Department of Molecular and Biomedical Sciences.

The instrument is being incorporated into fresh and marine water testing in the Republic of Korea and the researchers say they’ll give several devices to state officials to test and use in the field in Maine.

The researchers published their findings in the journal Biosensors and Bioelectronics.

Making Sense of Maple Syrup

University of Maine News - Thu, 02/13/2014 - 12:18

Understanding more about the relationship between weather and maple sap flow, and how Maine syrup producers will adapt to climate change is the focus of research being conducted by a University of Maine graduate student.

Jenny Shrum, a Ph.D. candidate in the ecology and environmental sciences graduate program in the UMaine School of Biology and Ecology, is attempting to unravel the biophysical relationships between weather and sap flow. The goal is to better understand what drives flow and how expected trends in climate may affect the processes and harvesters in the future.

Shrum plans to collect on-site weather station data and sap flow rates at three test sites and to interview small- and large-scale producers to determine if those who have been managing sugar maple stands for years will be more or less resilient to climate change, and if large-scale producers will be better equipped to adapt. Her research is supported by the National Science Foundation and EPSCoR through UMaine’s Sustainability Solutions Initiative and its Effects of Climate Change on Organisms research project.

The physiological process for sap flow is not completely understood, Shrum says. It involves a complex interaction between freezing and thawing of the xylem tissue within the tree, and the molecule sucrose which maple trees use to store carbohydrates between seasons.

“When the tree defrosts, the frozen liquid in the tree becomes fluid and that provides a medium for the sugars that are stored in the trunk to get to the branches,” Shrum says, adding that in order to continue flowing, the ground also has to be defrosted so the tree can pull in water during the next freeze cycle and recharge the positive pressure in the trunk to restart sap flow.

Sugar maple trees grow as far north as New Brunswick and as far south as Georgia, yet maple syrup is only produced commercially in the 13 most northern states because of the colder weather, Shrum says.

In Maine and other northern areas, more than one freeze-thaw event happens during the winter. This lets the process repeat and allows the season to last between six and eight weeks as opposed to a few days, which is likely in southern states such as Georgia and Missouri, where maple trees grow but aren’t commercially tapped. Warm weather or microbial build-up in taps usually ends the season, according to Shrum.

In Maine, the season usually starts sometime between the middle of February and the middle of March, and continues for about six weeks, Shrum says.

“This winter has been really weird; we’ve had really warm weather and really cold weather and as far as sap flow, that might be a good thing,” Shrum says. “But not enough is known.”

One change that has been proven is the start time of the sap season.

“Studies are starting to show that the preferred block of time for tapping is starting earlier if you base it on ideal temperatures,” Shrum says, citing a 2010 Cornell University study by Chris Skinner that found that by 2100, the sap season could start a month earlier than it does now.

For big-time operations, Shrum says an earlier season probably won’t be a problem because they can just tap their lines earlier, but she’s not sure how smaller Maine operations will adapt.

“They might not be able to change their season,” she says. “A lot of the smaller operators have multiple jobs; they make money off maple syrup, but also in other fields such as woodcutting or construction. It just so happens maple syrup is a block of time when they’re not doing anything else, so it makes sense. But if that season changes, it might not fit into their schedule as well.”

Shrum will interview a variety of producers — small- and large-scale operators, people who have been tapping trees for 30 or more years and people who started within the past five years — to learn the reasons for tapping and better understand resilience within these groups.

To record weather and sap flow data, Shrum, who holds a bachelor’s degree in biology from Humboldt State University, will deploy weather stations at maple tree stands in Albion, Dixmont and Orono. She’s also using iButtons to record soil temperatures and time-lapse photography of the buckets to record hourly sap flow rates. She can then relate flow rates to variables the weather stations record, such as temperature, precipitation and sunlight.

Although climate change is likely to affect sap flow, Shrum is confident there will always be maple syrup made in Maine.

“None of the climate change scenarios that have come up result in maple trees not growing in Maine. We’re definitely still going to have freezing events in Maine; it’s not going to get so warm that that’s not going to happen,” she says.

Shrum says maple syrup could become a big commodity in Maine if more of a market was created through government incentive plans, and if the state decided to make it a priority — similar to Vermont.

“Everything is good about maple syrup. There’s very little that’s controversial about it, and the biology is fascinating,” Shrum says.

Hayes Quoted in BDN Article on Babies Exposed to Drugs

University of Maine News - Wed, 02/12/2014 - 11:36

Marie Hayes, a psychology professor at the University of Maine, spoke with the Bangor Daily News for the article “For Maine babies exposed to drugs, disadvantageous mount after leaving the hospital.” Hayes spoke about her ongoing research on the health of drug-affected babies conducted with Mark Brown, chief of pediatrics and director of nurseries at Eastern Maine Medical Center. She said many babies face challenges after leaving the hospital, such as poverty, poor nutrition and parents with limited parenting skills, which makes it difficult to isolate the effects of prenatal exposure to opiates. She added many of the infants also are exposed to tobacco and alcohol while in the womb. Hayes’ research has also determined babies prenatally exposed to drugs have displayed subtle problems developing their stress response, which could lead to a low tolerance for frustration and new challenges as they grow up.
