Editor’s Note: This story was written by Emily Woodward, public relations coordinator for Marine Extension and Georgia Sea Grant. It was originally published in the UGA Marine Extension and Georgia Sea Grant Newsletter Volume 4, issue 5.

Four coolers, two shovels, countless sampling vials and five people pile into a vehicle headed to a secluded salt marsh on Sapelo Island, Georgia. It’s a surprising amount of equipment needed to study the microscopic community of organisms responsible for the health of Georgia’s most abundant coastal habitat, the salt marsh.   

“Plant microbiome research, I always say, is about 10 years behind human microbiome research,” says Joel Kostka, jointly appointed professor of biology and earth and atmospheric sciences at Georgia Institute of Technology.

Roughly half of the cells in the human body are microbial. These microbes, mostly bacteria, all have different functions; some make us ill, but most keep us healthy by helping with digestion or preventing infection. Together, these microorganisms make up the human microbiome.

The same is true in the plant world, though little is known about plant microbiomes, particularly those associated with salt-tolerant coastal plants like Spartina alterniflora, which dominate Georgia’s salt marshes.  

With funding from Georgia Sea Grant, Kostka is studying the microbes intimately associated with Spartina to better understand how the plant microbiome supports the health of Georgia’s salt marshes.

“In a way, this is discovery-based science because no one has studied the microbes that are intimately associated with these plants,” says Kostka. “When you look at the marsh from a large scale it really looks constant and consistent, but when you get down at the micro level you see all kinds of differences. There's a lot of complexity there.”

The research team wants to know how the microbial community changes as you move from the interior of the marsh, where the growth of Spartina is stunted and the plants are short, to the taller, lush marsh growing near the tidal creeks.

At the site, they measure salinity, oxygen, and pH as well as the height and density of Spartina at different spots along a transect. A hole punch is used to collect samples of Spartina blades, which will be measured for nutrients, like phosphorous and nitrogen. Soil samples and root material are taken back to the lab where the latest gene sequencing and metagenomics methods will be used to identify individual microbes and understand the microbial processes that improve the health of the plant. 

“We have a number of parameters that we can measure to determine whether the plants are healthy, and then we go in and look at the microbes in more healthy plants versus less healthy plants, and see how those microbes are changing,” says Kostka.

It’s a lot of data to collect and the work isn’t easy, especially when trudging through knee-high marsh mud in 90-degree temperatures.

Luckily, Kostka has an extra set of hands to help with the sampling.

Elisabeth Pinion, an AP environmental science teacher from Cumming, Georgia, is working alongside Kostka and his team. Pinion is one of 16 educators participating in Schoolyard Program of the NSF-supported Georgia Coastal Ecosystems (GCE) Long Term Ecological Research (LTER) Project, which is hosted every summer at the University of Georgia Marine Institute on Sapelo Island. As part of the program, teachers spend a week on the coast, shadowing different researchers in the field and learning about sampling methods and processes that can be taken back to the classroom.

Pinion recognized similarities between the topics she covers in class and the research methods used for this project.

“Studying parameters that determine the productivity of different ecosystems is something that we generally spend a lot of time on,” says Pinion. “What they are looking at is very applicable to the classroom.”

Throughout the week, Kostka will have the opportunity to engage multiple educators in the field, showing him or her how they collect samples for microbiology and discussing the important ecosystem services that salt marshes provide.

"The Schoolyard Program is a great way to give the teachers a behind-the-scenes look at how science is conducted, including sometimes having to rethink your strategy once you get out in the field," said Merryl Alber, professor of marine sciences at UGA and lead PI of the GCE LTER project. "It’s also beneficial for researchers, who have a chance to interact with the teachers and think creatively about how to bring the science back into the classroom.”

Kostka recognizes the importance of making his research accessible to educators and students, which is why he used a portion of his Georgia Sea Grant funding to support three of the educators participating in the Schoolyard Program.

The trip to Sapelo is the first of many trips the research team will make to the coast. They plan to sample sites at two other barrier islands; Tybee Island and St. Simons Island, in the coming months.

Kostka hopes results from the project can be used to develop innovative methods for improving salt marsh restoration practices in Georgia. One example would be to create plant probiotics that could be applied to Spartina seedlings when planting new marshes.

“We could grow beneficial microbes in the lab and add them to the naked roots during planting, which would help the plant to take hold in the intertidal zone,” says Kostka.

“With sea level rise and increased coastal development, restoration activities will be more important to maintaining the productivity of Georgia’s marshes,” says Mark Risse, director of Marine Extension and Georgia Sea Grant.  

“Funding research like this, that helps us improve attempts to establish native vegetation, will inform future restoration projects and hopefully make them more economically and environmentally efficient.”

A long time ago, in a city far, far away, a mathematician solved a puzzle, the solution of which made our modern, connected world possible. Georgia Tech's School of Music and School of Mathematics have teamed up with local Atlanta artists to create a performance combining contemporary dance, original music, and storytelling. Called The Seven  Bridges of Königsberg, the concert celebrates this history and aims to spark people’s curiosity and convey the wonder of mathematics.

The classic puzzle that inspired Leonhard Euler to found the fields of topology and graph theory (or network theory) asked the simple question: Is it possible to cross all of the seven bridges of the city of Königsberg exactly once, with no repetition or backtracking? 

Euler was not content with a yes-or-no answer. Instead he began to think about the nature of connectedness in a mathematical way, as it applies to all possible cities with any number of islands and bridges; as well as to networks of transportation, commerce, and communication; to the pathways by which diseases or ideas spread; and ultimately to our contemporary interconnected life.

The Seven Bridges of Königsberg was selected by a new program called Science in Vivo, funded by the Simons Foundation, to receive one of its inaugural 10 awards as an Experimental Site “exploring what is possible when science experiences for the public are integrated into existing cultural gatherings.” 

The debut performance on Sept. 13, 2018 will take place on the Georgia Tech campus along Atlantic Ave, where an installation of the Seven Bridges of Königsberg puzzle was constructed earlier this year.   

To tell about the foundation of graph theory, the Georgia Tech Symphony Orchestra will perform a new composition by composer Marshall Coats, while a math team and dancers interpret the story and some concepts about graphs, as choreographed by guest artist Kristel Tedesco.

This performance will be repeated at the Bailey Center in the Kennesaw State University on Sept. 23, 2018. Other versions of the show will take place at public locations around Atlanta and the Southeast region in September and October.

In addition to the spectacle, the audience will have opportunities to explore mathematical puzzles and games and to personally engage with the mathematicians and artists.

The Seven Bridges of Königsberg is a production of Mathematics in Motion, Inc. and the Georgia Tech Schools of Music and Mathematics, with financial support from the Georgia Tech College of Design, the Georgia Tech College of Sciences, the Georgia Tech Office of the Arts as one of the Creative Curriculum Initiatives, and Science in Vivo.

Aug. 21, 2017, the first day of the school year: At noon the Georgia Tech campus morphs into a massive, festive solar-eclipse-watching party. Thousands sprawl on Tech Green and stand on roof tops to cheer the celestial event.

Meanwhile in Kentucky, James Boehm is part of an experiment by AT&T. The company is testing a device to enable Boehm – who has been blind since he was 13 – to experience the eclipse. The set-up includes a soundtrack, which “voices” the changes in temperature and brightness as the moon’s shadow covers the sun. That accompaniment came from researchers in the Georgia Tech Sonification Lab.

That story leads the first season of the College of Sciences’ podcast. The people who made the 2017 eclipse-watching party possible now offer another treat: ScienceMatters, a podcast celebrating discoveries and achievements – the “Wow” and “Aha” moments – of Georgia Tech scientists and mathematicians.

Season 1 is now available at sciencematters.gatech.edu

The start of the school year can be discombobulating. Fortunately, many questions that come up are common from semester to semester.

Here, academic advisors in the College of Sciences share their answers to questions they’ve heard frequently from new and returning students during the first few days of a new semester.

Is it true that I shouldn’t take two lab classes in my first semester?
Your course load is a personal decision, best discussed with your academic advisor. That said, for some science majors, such as biology, we do recommend that students take two labs in their first semester to stay on track for timely progress through the degree.

How many credit hours should I take?
Again, the course load is a personal decision. Taking 12–14 credit hours during the first semester allows you to acclimate to the course work at Tech and to explore co- and extracurricular ways to take part in the campus community.

Continue here for the full story.

The College of Sciences joins the rest of Georgia Tech in Ramble In, a first-day-of-class fun event organized by Omicron Delta Kappa.
