Middle schoolers join a Chicago research lab in the quest for new antibiotics

July 10th, 2024 by

As part of an Illinois-Indiana Sea Grant (IISG) funded research project, a Chicago middle school girl has discovered a new compound in goose droppings that has shown activity against cancer. As a result, she will soon be an author on an article submitted for publication in a biomedical research journal.

Camarria Williams was recruited through the Boys & Girls Club of Chicago along with other middle schoolers to take part in an opportunity in a University of Illinois Chicago laboratory to do real science.

“Chicago has a long history of disparities, whether they’re rooted in socioeconomics or race-based policies—this is an opportunity to use high end biomedical science to help bridge some of the documented gaps in STEM participation,” said Brian Murphy, a medicinal chemist in the UIC College of Pharmacy, who leads this program. “By working with local organizations or community centers we can bring citizens into the process of discovering antibiotics.”

Murphy, along with Jin Yi Tan, a UIC graduate student who leads a team of volunteer graduate students and postdoc mentors in the Chicago Antibiotic Discovery Lab, developed this program to engage youth from marginalized neighborhoods in STEM education using a novel approach. The kids are introduced to scientific experiments and participate in a variety of learning opportunities.

At the center of these activities is the assignment for these young scientists to collect samples from their environments to test in the laboratory for possible antibiotic properties, and they are very much involved in making decisions throughout the screening process.

Creating the conditions that made it possible to bring youth into the lab to do this work began a few or more years ago when Murphy set out to make the search for antibiotics in the environment cheaper, better, and more efficient.

With some disease-causing microbes developing resistance to our medicine chest of antibiotics, this work has become especially important.

 Murphy and his team adopted technology that would help them develop a leaner, more efficient microbial library that would have fewer redundancies. And they repurposed older technology to allow them to very rapidly screen for antibiotic activity.

“When I joined the lab,” said Tan, “I worked to integrate these different innovative methods into one pipeline to make the process much more efficient, as well as add high throughput robotics to automate many of the steps.”

UIC graduate student Jin Yi Tan leads a team of volunteer graduate students and postdoc mentors in the Chicago Antibiotic Discovery Lab. She developed this Sea Grant project to engage youth from marginalized neighborhoods in STEM education.

Automating the process has also made the process simple enough that Tan, who was funded as an IISG Grad Student Scholar to build on Murphy’s project, could teach middle school students how to do it.

The team has worked closely with the James R. Jordan Boys & Girls Club in the near west side of Chicago as well as the Bartlett J. McCartin Boys & Girls Club in the Bridgeport neighborhood to recruit youth to take part in the program.

Over the span of several years, 22 have volunteered for this opportunity—three groups of 5−7 middle school-aged Boys & Girls Club members and a small group of high school students.

The youth who joined the Chicago Antibiotic Discovery Lab chose places and objects to sample for bacteria in their environment—they sampled lake water, insects, and flowers, but also swabbed different kinds of surfaces such as a playground slide and an air conditioning filter.

Altogether, they collected 40 samples and processed over 5,500 antibiotic bioassays. Of these, some were chosen for further analysis and the most promising ones were eventually screened by Tan.

“You can expect that only about 1 to 5% of any isolates would really be a hit,” said Tan. “Some of the samples did have antibiotic properties that were already known—they had been previously discovered. It’s still really exciting for the kids when we tell them that we found an active antibiotic molecule in their sample.”

Camarria Williams’s successful sample was of goose droppings near a pond in Chicago’s Garfield Park. Further testing revealed it to be a new compound of a known family of compounds that have shown disease-fighting properties in the past. The small differences in this molecule may indicate that its disease-fighting properties are different too. Much to everyone’s surprise, the sample also showed activity against several different cancer cell lines.

“We identified some compounds to be cyclic peptides, which are famous for having biologic activity,” said Murphy. “Amazingly, it turns out these particular compounds don’t have antibiotic activity, but they do have cytotoxic activity—activity against some cancer cell lines.”

Other compounds in the goose droppings are being tested for their antibiotic activities.

While the destination, in terms of discovering a new medicinal tool is potentially groundbreaking for the students that go through this program, the journey—the learning process—is the real reward.

Over 13 weeks, as the youth screened their samples, they engaged in STEM education sessions focused on Great Lakes environmental issues, biology, engineering, and robotics. Throughout, they were introduced to careers related to the subject at hand, including engineering and other sciences. For example, IISG’s Aquatic Education Associate Megan Gunn was interviewed by the kids about her experience doing Great Lakes science.

“We work with really small groups, so a lot of the mentoring is one to one,” said Tan. “We really notice kids and their interests. One cohort was really interested in the engineering component. And then our most recent cohort was more interested in biology. Since it’s such a small group, we can tailor to their interests.”

Tan shared her experience of watching some students become more confident over the course of the program. “I think the most rewarding part for me is seeing the progress as kids became more confident in themselves over time,” she said. “Like, yeah, I can program stuff. I can do this. I chose these samples.”

Murphy is hoping to continue bringing youth into the antibiotic discovery process, but perhaps with more of an emphasis on high school students.

“The idea would be to pair high school students with near-peer mentoring from graduate students and postdocs,” said Murphy. “All at a time when they’re starting to think about being adults themselves and are asking, is it possible for me to have a career in science?”

You can take steps to reduce your exposure to PFAS contaminants

July 8th, 2024 by

PFAS are chemicals commonly found in consumer goods that are making their way into drinking water supplies where they are a risk to human health, but there are steps people can take to protect themselves.

PFAS, per- and polyfluoroalkyl substances, are a group of more than 15,000 man-made chemicals that are sometimes added to products to help them resist grease, oil, water, and heat. These “forever chemicals” are found in a wide array of consumer goods, including clothing, cosmetics, food packaging, carpets, cookware, and cleaning products. As a result of their widespread use, PFAS have migrated into soils, lakes, rivers, and streams across the U.S.

No level of PFAS exposure comes without risk to human health, according to a recent press release from the U.S. Environmental Protection Agency (EPA). PFAS break down slowly and can accumulate in aquatic plants and animals as well as people. Exposure to PFAS through the skin or digestive system has been linked to increased risk of certain cancers, kidney and heart disease, and reproductive issues like low birth weight and birth defects. This spring, EPA announced the first federal legal protections to protect public drinking water from PFAS.

Sarah Zack, pollution prevention specialist with Illinois-Indiana Sea Grant, works with the public to raise awareness about water contaminants, including PFAS.

“It’s not easy to reduce our risk from PFAS chemicals because they are ubiquitous in the environment,” Zack said. “But there are some simple ways to reduce your exposure and protect your health.”

  • Replace nonstick pans at the first sign of scratches, and do not heat beyond the recommended temperature, which is typically 400 degrees Fahrenheit. Avoid using nonstick cookware altogether, if possible, and opt for stainless steel, cast iron, or ceramic.
  • Microwave popcorn bags, takeout containers, and fast-food packaging can be coated with PFAS to prevent sticking. Be a cautious consumer and do research before eating food from this packaging.
  • Avoid stain-resistant carpets, upholstery, and other fabrics. Vacuum regularly to remove PFAS that can accumulate in dusty fabrics.
  • Leave shoes at the door to avoid tracking chemicals into your home.
  • Check advisories before eating locally caught seafood.
  • Contact your public water utility about whether your drinking water has been tested for PFAS. If you are on a private well, conduct regular testing. Consider an at-home water filtration system if you are concerned about the FAS level in your water.

You can learn more by listening to a University of Illinois Extension Spotlight on Natural Resources podcast, in which Zack discusses the problem of PFAS.

IISG summer initiatives include interns, water safety, and aquatic invasive species

June 27th, 2024 by

Summer 2024 is officially underway and if it’s summer, it’s intern season at Illinois-Indiana Sea Grant (IISG). Every year since 2011, we have hired college undergrads to spend the summer working closely with our specialists and taking part in other learning opportunities.

This year five interns have joined us and they will work in a variety of areas including sustainable land use planning, water resources and economics, green infrastructure, and environmental education.

Two additional interns were hired through Sea Grant’s national Community Engaged Internship program that aims to broaden participation in water resources by offering paid internships to undergrads from under-resourced, underrepresented and/or indigenous and tribal populations. We are collaborating with the National Park Service and Chicago Wilderness to co-host these two interns.

Summer is also prime time to think about water safety as the hot weather kicks in and many of us head to the beach. IISG has developed a four-part video series in partnership with the Indiana Dunes National Park to encourage safe recreation in Lake Michigan. The videos explain dangerous waves and currents and even cold-weather concerns and provide sensible safety tips. And don’t forget to check with our buoys for up-to-the minute lake conditions before you head out.

In Illinois state parks and other natural areas, conservation police officers are up to speed this summer on aquatic invasive species (AIS)—they have new knowledge and tools to combat the spread of these species and protect the state’s natural resources. Recently, 150 officers attended a hands-on workshop that was developed by our AIS team in collaboration with Carena van Riper’s lab—she’s a conservation psychologist at the University of Illinois. Through this training, the officers were able to directly engage with various AIS specimens and they learned how to distinguish between native and invasive species.

In the latest issue of Outdoor Illinois, an Illinois Department of Natural Resources online journal, you can read an update to an ongoing study to track fish in the busy downtown waters of the Chicago River and connected waterways. The team from IISG, Shedd Aquarium, and Purdue University Department of Forestry and Natural Resources is seeing some impacts on fish movement from the river’s combined sewer overflows. For example, last summer when, in response to a large rainstorm, raw sewage was pumped into Bubbly Creek, acoustically-tracked fish rapidly left this area and did not return throughout the summer.

In IISG staff news, we welcome Julie Fiorito, our new K-12 education specialist. The focus of Julie’s work is to increase Great Lakes literacy among Illinois and Indiana youth through development, delivery, and evaluation of science-based educational programming. Fiorito has extensive experience as a high school teacher planning, directing, and coordinating various educational programs. She earned a Bachelor of Science in biology education from Illinois State University and a Master’s from the University of Illinois. 

Kayla Wright is our new community resilience extension specialist. A new member of Kara Salazar’s Sustainable Community Planning Team, Kayla will use her local government and community engagement expertise to provide leadership and support to further efforts with the Great Lakes Environmental Justice Thriving Communities Technical Assistance Center and the Indiana Renewable Energy Planning and Technical Engagement Collaborative. She has a bachelor’s degree from Indiana University.

Summer brings a round of educational opportunities for us to share with residents, decision-makers, educators, and partners too. Some examples:

  • Registration opens on July 1 for the American Citizen Planner Indiana fall session. This 16-week course develops knowledge and skills for residents, including advisory plan commissioners or citizen advocates, who are unfamiliar with the concepts and regulations of local government planning.
  • The IISG education team will engage 5−12 grade educators in a workshop on July 24−25 at the Wild Mile along the Chicago River. Participants will hear about the history and ecology of the site, as well as learn water quality testing skills to bring back to their students.
  • Do you want to know more about local watershed concerns and volunteer to help keep them healthy? You can register until August 14 to join the Illinois-Indiana Master Watershed Stewardship Program class, which will take place at Purdue University Northwest from August 20 to October 8.
  • On August 10, come ready to help remove rusty crayfish from the Fox River in Illinois’ Kane County at the annual Rusty Rodeo. Our AIS team will be joining in the festivities to share information about invasive crayfish.

Fish larvae may be more affected by microplastics from their parents’ exposures than theirs

May 28th, 2024 by

Microplastics have been found in the water just about everywhere, as well as in fish and other organisms. At this point, the effects these microplastics are having on fish larvae growth and development, as well as their behavior, isn’t well understood. Nor is any combined impact with other known contaminants.

An Illinois-Indiana Sea Grant faculty scholar set out to gain some insights on these issues and found that fathead minnow larvae are more impacted when their parents have been exposed to microplastics rather than when they ingest it themselves.

Jessica Ward, an animal behavior scientist at Ball State University and graduate student Kenzie Persinger evaluated the impacts of microplastics and a common environmental estrogen on early life stages of the fathead minnow. (Fathead minnows are one of EPA’s model species for toxicology research and are widely used in lab work.)

“One of the main questions we hoped to answer was whether exposing parental fish to microplastics, as well as microplastics associated with endocrine disrupting chemicals, showed downstream behavioral effects in offspring,” said Ward.

The contaminants were introduced through the fish’s diet in amounts that reflect what they would likely experience in the real world. Adult minnows were exposed to microplastics alone or along with estrogen and then allowed to spawn.

After hatching, half of these larvae received continued exposure for 21 days and both this group and the unexposed control group were tested in how they performed in swimming trials.

The researchers measured a significant overall effect on fathead minnow offsprings’ swimming performance when their parents were exposed to microplastics, with or without estrogen. These larvae showed more hyperactive behavior.

“Compared to the control group, the larvae swam farther and faster, which is an indicator of hyperactive behavior,” said Ward.  “Hyperactivity is thought to increase the probability of predation.”

The researchers observed no further changes in larvae that received more exposure after hatching, and no significant effects were observed from larvae only exposed after hatching.

“This suggests that parental exposure has a stronger effect on offspring behavior than direct exposure of the offspring themselves,” said Ward.

Cooperative Lake Michigan research effort focused on critical management issues and knowledge gaps

April 9th, 2024 by

Every five years, Lake Michigan is the focus of intense research and monitoring when scientists come together to answer critical questions and fill information gaps. A report summarizing the results of the most recent data collection on the lake is now available.

Each year since 2002, through the Cooperative Science Monitoring Initiative (CSMI), multiple federal, state, and university scientists gather on one of the Great Lakes to take part in coordinated research. CSMI is a binational program organized through the U.S. Environmental Protection Agency Great Lakes National Program Office and Environment and Climate Change Canada.

Lake Michigan was slated for 2020 to be its CSMI field year, but due to the pandemic, the sampling actually took place in both 2020 and 2021. Research priorities included learning more about the lake’s changing food web dynamics, the impacts of contaminants and bacteria, and the connections between watersheds and tributaries to the lake’s water quality.

Quagga mussels featured prominently in the key findings of the compiled 2020 research results—they are the dominant invertebrate species in the lake. The good news is that the quagga mussels’ population density has somewhat stabilized, on the other hand, their numbers in deeper areas of the lake continue to slowly expand.

“Quagga mussels continue to play a key role in nutrient and primary production dynamics in Lake Michigan,” said Paris Collingsworth, Illinois-Indiana Sea Grant (IISG) Great Lakes ecosystem specialist and Purdue University researcher. “Quantifying the effects of these mussels on the energy flow throughout the lake is an important concern for the management community of Lake Michigan.”

Collingsworth provides leadership in collaboration with EPA scientists, defining critical questions and coordinating research efforts of various agencies for large-scale studies. He works with the lake partnerships for each lake as they define CSMI research priorities, and with scientists as they set up studies and analyze data. 

The significant presence of quagga and zebra mussels, or dreissinids, in Lake Michigan and their consumption of so much of the energy of the lower food web have left lake waters clear. CSMI research showed that this extreme clarity has shifted the vertical distribution of planktonic organisms lower in the water column to avoid high ultraviolet radiation in surface waters.

Mortality from ultraviolet exposure may also be a bottleneck for fish larvae survival and potential recruitment in Lake Michigan, but some species may fare better than others.

For example, higher pigmentation on bloater larvae compared to those of alewife suggests that bloater can endure ultraviolet exposure. In fact, findings reveal that while alewife larvae catches in 2021 were 3.7 lower than in 2015, bloater densities were 2.2 times higher in 2021.

Researchers found that quagga mussels are having an impact on fish populations in other ways. When the quagga mussel veliger, a larval stage, is part of the larval fish diet, this reduces fish growth and survival rates.

“The long-term tracking of invasive mussels and other lower food web organisms by CSMI partners has been extremely helpful to all lake managers because it improves our understanding of lake ecosystem processes, informs management decisions and provides sound scientific information on a changing ecosystem that can be shared with Great Lakes anglers and stakeholders,” said Vic Santucci, Lake Michigan fisheries program manager with the Illinois Department of Natural Resources.

The scientists also studied contaminants in Lake Michigan and found evidence that spottail shiner may be exposed to a sediment source of PFAS (or per- and polyfluoroalkyl substances). These compounds are called “forever chemicals” because they don’t break down in the environment.

To learn more about these results and many others, the Cooperative Science and Monitoring Initiative Lake Michigan 2020 Report with key findings and an executive summary is on the IISG website.

 

 

IISG finds new approaches to help communities and others make informed decisions

March 27th, 2024 by

This spring, Illinois-Indiana Sea Grant (IISG) is sharing opportunities to further research, engage audiences with new information, and bring experts together to share knowledge and set new goals.

The 2024 Graduate Student Scholars program is ramping up, with the program open to graduate students from institutes of higher learning in Illinois and Indiana. Applicants can request up to $10,000 to support research expenses, stipends, travel, or other activities that help expand the scholarly or societal impact of their research. To see how this program is going, you can read blog posts describing past and current scholars’ projects in our newsroom.

We have developed two new IISG education products that offer exciting approaches to facilitate learning. Both products are currently being pilot-tested and will be available later in the year.

First, years of support for high schools that incorporate aquaponics into their STEM classwork has led to the development of a new curriculum. Aquaponics is a form of sustainable agriculture that connects raising fish and growing plants through an interdependent relationship. The IISG High School Aquaponics Curriculum is nine lessons that comprehensively cover aquaponics but is also designed so that an educator can pull out a single component to reinforce classwork.

The second educational tool brings Great Lakes Areas of Concern (AOC) to the classroom using 360-degree virtual reality technology. IISG’s Ashley Belle and Megan Gunn developed an immersive experience along the Grand Calumet River in northwest Indiana.  Creating a novel way to introduce students to environmental science in the real world, the virtual reality images feature degraded areas of this AOC as well as sites that have been remediated and restored. The specialists also developed a complementary curriculum for use with middle and high school students.

In other news, I’d like to congratulate several well-deserved recent IISG award winners. Research Coordinator Carolyn Foley received the Purdue University Forestry and Natural Resources 2023 Outstanding Administrative/Professional Staff Member Award. Carolyn was recognized for her leadership, resourcefulness, and selfless contributions to the department and IISG. Carolyn has served IISG’s research program since 2010 and is the primary contact for questions related to requests for proposals and IISG-funded research projects. She also developed and initiated the IISG Scholars Program in 2021.

Greg Hitzroth, our aquatic invasive species (AIS) outreach specialist, was chosen for the 2023 Illinois Lake Management Association Lake Guardian Award. Since 2012, Greg has worked to inform key audiences to help prevent the spread of AIS in Illinois waters and in the Great Lakes. As IISG has become the primary source of AIS outreach and education in Illinois, Greg has come to be seen as a regional expert regarding the “organisms in trade” pathway. This characterization came about through his efforts to develop well-informed outreach tools as well as his willingness to open new doors and try new approaches to this work. 

Spring brings a round of educational opportunities for us to share with residents, decision-makers, researchers, and partners too.

  • To mark the fifth year of our native plant tournament, formerly known as “Mulch Madness,” we invite you to get ready for Rain Garden Rumble!

New research predicts potential flooding impacts on critical infrastructure

February 22nd, 2024 by

Climate change is bringing more extreme weather to the southern Lake Michigan region along with dramatically variable water levels. With the risk of flooding increasing, so are potential threats to infrastructure, to residents, and to coastal communities as a whole.

An Illinois-Indiana Sea Grant faculty scholar is using computer modeling to help communities protect critical infrastructure in the face of increased flooding risks. Chengcheng Tao, a professor of civil engineering at Purdue University, has developed an approach that incorporates risk assessment factors along with fluid-structure interaction simulations.

Fluid-structure interactions are what happens when a structure is impacted by a fluid force, like air meeting up with an airplane or, in this case, waves pounding on bridge supports. Risk assessment factors regarding infrastructure include scores for how vulnerable these structures are and how critical they are to the community and its residents.

The IISG scholars funding has helped Tao develop and test these model components on common bridge structures.

“Although I use the bridge infrastructure as an example in the study, the model can be applied to other infrastructure, like buildings or highways,” said Tao, who also is the director of Purdue’s Sustainable Infrastructure and ManUfacturing Lab  

Thus far, she has been using publicly available data, but with access to a treasure trove of historical data to inform the model components, results will be more finely tuned. Purdue graduate student Junyi Duan, who is a key contributor to this project and is funded through the IISG Scholars program as well, has collected historical records from government organizations that reveal how floods have impacted locations in the Great Lakes region.

After combining the risk model with historical data and the physical model data, Tao will have a very comprehensive, data-rich framework. With that, she plans on building a smart infrastructure warning system.

“In the future, when a flood system is headed to a location, a smart warning system can predict the flood risk beforehand, before the damage happens,” said Tao. “The warning system may recommend that a community pay more attention to particular sites or infrastructure components.”

Ultimately, she wants to create a smart platform that residents can use on their cell phones or computers that show their particular flood risk scores.

A smart infrastructure warning system can help even earlier in the process. For example, insights from the modeling can help inform future infrastructure designs and even local design codes.

In addition to connecting with local organizations and presenting their work at three American Society of Civil Engineers conferences, Tao and her students joined with Purdue Science K-12 Outreach to film educational videos about flood hazards that will be posted on YouTube as part of Purdue’s Superheroes of Science series.

Automated sampling equipment may aid in tracking microscopic aquatic invasive species

February 16th, 2024 by

When it comes to managing ecosystems to address the problem of aquatic invasive species, knowing where they are and in what numbers can be critical in helping prevent the spread. To that end, an Illinois-Indiana Sea Grant faculty scholar is automating sampling equipment for keeping track of the invasive spiny water flea to make the process easier and more efficient.

Spiny water fleas are native to European and Asian waters but were introduced to the Great Lakes in the 1980s, likely in ballast water. These microscopic zooplankton eat other zooplankton, which are the base of the Great Lakes food web, but spiny water fleas have spikes on their long tails, so they are not a desirable food item. Their populations have grown and, today, they can be found throughout the Great Lakes.

“Traditionally, the way we sample aquatic microorganisms, including the water flea, is to throw a net out into the water and pull it up slowly. This is cumbersome and you are only able to do one sample at a time,” said Sachit Butail, a professor of mechanical engineering at Northern Illinois University.

With input from scientists at NOAA, he has worked to improve the design of an automated device for sampling aquatic microorganisms to expand its capacity and accuracy. This motorized device that is lowered into the water has six chambers − water passes through a net into one of the chambers. Each time the device is brought up out of water, it revolves, securing a water sample for analysis.

This allows for the collection of multiple samples in different locations in one field day.

In laboratory testing, using chia seeds, the revised design significantly improved the device’s performance—it reduced contamination between the chambers, resulting in a more accurate analysis of each site sampled.

Butail, who does much of his research and development in robotics, sees this project as a step toward creating a fully robotic sampling device as well as an autonomous boat that can be controlled from the shore. His team has developed preliminary designs for the boat and they are trying out early versions of the robotic sampling device in a laboratory testing pool.

“The new robot, which is in the shape of a glider and has an attached net, is an early step toward developing new ways to offset the effort that is traditionally required to sample water flea in deep waters,” said Butail.

Looking to the future, he sees the potential of widespread use of this technology in addressing aquatic invasive species.

“I hope that one day robotic technology will become integrated with citizen science,” said Butail. “My hope is that at some point, we can have citizen scientists directly control robots that record underwater videos. I think that the scale at which that would give us data about invasive species would be really significant.”
