Asian carp DNA found in Wisconsin's Lake Michigan waters for first time

November 5, 2013 - Asian carp DNA has turned up in Wisconsin's Lake Michigan waters for the first time. The single positive water sample for the jumping silver carp was taken May 31 in Sturgeon Bay near Door County's Potawatomi State Park. "Even if the fish are in Lake Michigan, it's not too late to control the population and contain their spread," said CMU assistant professor of biology and Institute for Great Lakes research scientist Andy Mahon, who helped develop the environmental DNA search tool along with research colleagues at The Nature Conservancy and the University of Notre Dame. "The time to be proactive is now."

Using fish ear bones to help protect coastal wetlands

September 30, 2013 - Don Uzarski, CMU
professor of biology and director of CMU's Institute for Great Lakes Research and the CMU Biological Station, and his research team are reading information stored in the ear bones (otoliths) of fish to track fish movements. 

The otoliths in fish grow daily in layers, similar to rings in a tree trunk. Biology graduate student Lee Schoen and Jim Student, director of the Center for Elemental and Isotopic Analysis in the CMU College of Science and Technology, are taking thin slices of the otoliths and running them through a laser-equipped mass spectrometer, which picks up trace elements that the ear bones integrate from surrounding water, enabling the researchers to track the fish's pattern of visits to particular coastal wetlands.



heir research aims to provide the hard data necessary for better choices to be made about managing, restoring and protecting the Great Lakes basin's coastal wetlands.

Powerful Research: Using Supercomputers to Simulate Supercell Thunderstorms

September 27, 2013 - What occurs within a
thunderstorm that leads to the formation of destructive weather events such as tornadoes and downbursts? Associate professor of meteorology Leigh Orf is trying to answer this question, and in the process, is gaining national recognition for his expertise in using supercomputer modeling and simulation to study atmospheric disturbances such as supercell thunderstorms.

Supercells are the most powerful, long-lived thunderstorms. They exhibit a rotating updraft, and they are responsible for nature's mightiest twisters



National Institute for Computational Sciences (NICS) recently published "Simulating Supercell Thunderstorms," covering Orf's storm simulation studies and ongoing research, the objective of which is to capture the entire life cycle of a supercell thunderstorm that produces a strong, long-lived tornado.

Along with colleagues Bob Wilhelmson of the National Center for Supercomputing Applications (NCSA) at the University of Illinois and Matthew Gilmore, associate professor of atmospheric science at the University of North Dakota, Orf recently ran supercell simulations on the Blue Waters supercomputer located at NCSA and rendered them on a system housed at Oak Ridge National Laboratory.

These simulations  still being analyzed  are guiding the research team in designing new simulations to be run at the Texas Advanced Computing Center, all of which are resources of the National Science Foundation's Extreme Science and Discovery Environment (XSEDE)  the most advanced, powerful and robust collection of integrated digital resources and services in the world.

"With enough simulations, we hope to have a spectrum of storms to investigate, from storms that produce the weakest tornadoes, to those that produce the most devastating, in addition to storms that do not produce tornadoes at all," Orf explains.

Recent similar research  published in the latest edition of NCSA's Access magazine  that Orf is conducting along with Wilhelmson and Eric Savory of the University of Western Ontario has them using the Kraken supercomputer at NICS to create storm simulations in environments known to be conducive to creating downbursts.

Downbursts are created by a column of sinking air that, after hitting ground level, spreads out in all directions and are capable of producing damaging straight-line winds in the range of 80-150 mph. Occurring 10 times more often than tornadoes, they produce a debris pattern in parallel straight lines, which distinguishes them from tornadoes, which leave a rotational damage pattern.

Orf and Savory are exploring the specific stresses that downbursts present to structures, such as power transmission lines, and their simulations are producing a more physically realistic wind field not found in simpler models.

They are hoping that advances in supercomputing power will bring them closer to answers that will ultimately help meteorologists issue better short-term forecasts and more accurate, timely, and targeted warnings for these types of storms.

Undergraduate student conducts world-class nuclear physics research in Canada

September 12, 2013 - Physics undergraduate Caleb Bancroft at TRIUMF laboratory in Vancouver, Canada
student Caleb Bancroft recently spent eight days at TRIUMF laboratory in Vancouver, Canada conducting nuclear physics research. Caleb prepared and performed an experiment that investigated the shape of very exotic atomic nuclei.

TRIUMF is one of the world's leading subatomic physics laboratories. In addition to basic research in nuclear and particle physics, TRIUMF researchers use accelerators to produce medical isotopes which are, for example, used in the diagnostics and treatment of cancer.

The experiment that Caleb participated in involved an international team, led by CMU assistant professor of physics Kathrin Wimmer. Their goal was to explore the phenomenon of shape coexistence in heavy Strontium isotopes. While some nuclei are round like soccer balls, others exhibit a more deformed shape, along the lines of what an American football looks like. In the case of the Strontium isotopes, the transition between spherical and deformed nuclei is very abrupt - only two additional neutrons change the shape of the nucleus completely.

In order to investigate this sudden change, a beam of radioactive 94Sr, consisting of 38 protons and 56 neutrons, was guided to the experiment where it collided with a foil containing Deuterium, a special form of Hydrogen. In some cases, only one neutron was transferred in the collision onto the 94Sr nucleus, making it 95Sr with 57 neutrons. The properties of this newly formed 95Sr were then investigated in great detail to draw conclusions about the rapid shape change in the Strontium nuclei.

The success of the experiment was a major breakthrough for the TRIUMF facility. Before, the heaviest beam that was accelerated and used for experiments at TRIUMF had a mass number of 30. Now, it is possible to do experiments with nuclei that are over three times more massive. This allows researchers to do many more exciting experiments and gives CMU physics majors the opportunity to participate in cutting-edge science.

Chappaz investigates molybdenum as one of the two key trace elements for the development of life

September 11, 2013 - The Goldschmidttriumf-research-300Conference, the world's largest geochemistry conference, recently met in Florence, Italy from August 25-30, where thousands of geoscientists presented their latest research. One of them, Dr. Steven Benner from the Westheimer Institute of Science and Technology in Gainesville, Fla., attracted a lot of attention.  

He presented a new hypothesis that life in the solar system may have begun on Mars billions of years ago. Benner's theory is based upon results that suggest minerals containing the elements boron and molybdenum are key in assembling atoms into life-forming molecules. Molybdenum is a unique trace metal, since it is required for nitrogen assimilation for all life forms on Earth.

Dr. Anthony Chappaz, assistant professor of geochemistry within Central Michigan University's Institute for Great Lakes Research and the Department of Earth and Atmospheric Sciences, is a recognized expert on molybdenum geochemistry. Along with colleagues from the University of Copenhagen and Princeton University, he also presented some new research results on how molybdenum can be used to reconstruct the rise of oxygen concentration in the ancient ocean.

This month a new postdoctoral researcher is joining Chappaz's research group in the GEM Labto investigate molybdenum geochemistry under low oxygen conditions. In light of Dr. Benner's recent presentation at the Goldschmidt Conference, this project - funded by the National Science Foundation - could bring new insights into how life may have started.

Biology graduate student conducts shrimp research Down Under

July 18, 2013 - CMU graduate student SamSam GlavesGlaves from Clovis, Calif. recently spent time conducting research in Brisbane, Australia. From January through April, Sam and his research colleagues studied the germ line development of the Kuruma shrimp, Penaeus japonicas, in an aquaculture setting. They are hoping that their findings will benefit aquaculture breeding practices and help answer prevalent germ line developmental questions for this particular shrimp species, as well as others that follow the same patterns.

Sam said the trip was extraordinarily beneficial for his research progress and "an amazing opportunity not only to experience a different culture, but to experience a different way of thinking, learning and talking about our universal field of biology."

Sam collected Kuruma shrimp samples at Bribie Island, the smallest and most northerly of three major sand islands forming the coastline sheltering the northern part of Moreton Bay, Queensland. He conducted his molecular research on the shrimp at the University of Queensland, a research-intensive institution in the top 1% of universities world


Sam studies under the guidance of biology professor Phil Hertzler and plans to graduate in December 2013 with a Master of Science in biology.

Pear-shaped atomic nuclei offer clues into nature of matter

May 28, 2013 - An international team of Pear-shaped atomic nuclei offer clues into nature of matternuclear physicists, including CMU assistant professor of physics Kathrin Wimmer, has found that some atomic nuclei can assume asymmetric 'pear' shapes.

The researchers' findings, published in the May 9 issue of the journal Nature, landed the coveted cover story and could be the key to understanding one of the great mysteries of the universe - the reason for the Big Bang's creation of a massive imbalance between matter and antimatter.

The reason behind the imbalance is one of physics' great mysteries. In particle physics, four basic forces dictate how matter behaves - gravity, electromagnetic forces, "strong" interactions and "weak" interactions. Physicists have been searching for signs of a new type of force or interaction to explain the matter-antimatter imbalance.

Most nuclei that exist naturally are not spherical. Wimmer and her colleagues decided to focus on pear-shaped nuclei because their unusually asymmetrical shape would make the effects of the new force much easier and stronger to detect. These nuclei get their shape from positive protons that are nudged out from the center of the nucleus by asymmetrical nuclear forces, yielding more mass at one end of the nucleus than the other.

Until now, it was difficult to observe pear-shaped nuclei experimentally. However, a technique pioneered in the Isotope Separator Facility (ISOLDE) at CERN, the European laboratory for nuclear physics research in Geneva, has been used successfully.

To determine the shape of the nuclei, the research team accelerated radium and radon atoms and smashed them into tin, nickel and cadmium. However, because the positively charged nuclei repelled each other, nuclear reactions were not possible. The result was the excitation of the nuclei to higher energy levels and the production of gamma rays, with the pattern of gamma radiation revealing the pear shape of the nucleus. 

The experimental observation of nuclear pear shapes is important for understanding the theory of nuclear structure and for helping with experimental searches for electric dipole moments (EDM) in atoms.

The study's results will help direct ongoing research for EDM that are currently being conducted in labs across North America and Europe, helping to advance the search for understanding the nature of the building blocks of the universe.

The research team, which included scientists from the UK, Germany, the USA, Switzerland, France, Belgium, Finland, Sweden, Poland and Spain, was led by professor Peter Butler from the University of Liverpool's Department of Physics.

First published in 1869, Nature is the world's most highly cited interdisciplinary science journal. Most scientific journals are now highly specialized, but Nature is among the few that still publish original research articles across a wide range of scientific fields. Published weekly, papers in this international journal feature the finest peer-reviewed research in all fields of science and technology.

Mahon and research team find that Asian carp DNA is not widespread in the Great Lakes as previously thought

April 5, 2013 - Assistant professor of biology and Institute for Great Lakes Research scientist Andrew Mahon, along with scientists from the University of Notre Dame and The Nature Conservancy, recently published their research on Asian carp DNA throughout the Great Lakes in the Canadian Journal of Fisheries and Aquatic Sciences. 

Silver and bighead carp - which gorge on plankton that all fish consume - are of particular concern to the Great Lakes ecosystem, since they are large fish that can quickly reproduce and unravel the food chain that supports a $7 billion fishing industry. In their latest study, the research team found that at least some Asian carp have found their way into the Great Lakes, but there is no evidence that they are as widespread in the Great Lakes basin as previously thought. 

Between September 2009 and October 2011, Mahon and his colleagues collected more than 2,800 water samples from parts of the Great Lakes and tributary rivers. Laboratory analysis yielded 58 positive hits for bighead or silver carp in the Chicago Area Waterway System, a network of rivers and canals linked directly to Lake Michigan, and 6 in western Lake Erie. Some of the Chicago eDNA was found in Lake Calumet, where a live bighead carp was caught in 2010 and three others were snagged in 1995 and 2000.

The results of their research contradict earlier government studies that have said many of the positive water samples detecting Asian carp DNA in or near the lakes in recent years could have come from other sources, such as excrement from birds that fed on the carp in distant rivers, or via boats and other pathways. While these previous studies acknowledged the presence of eDNA, government researchers disagreed that the findings signaled the presence of live fish.

Dr. Christopher Jerde, lead investigator on the latest study and a scientist at the University of Notre Dame, said, "Looking at the overall patterns of detections, we remain convinced that the most likely source of Asian carp DNA is live fish." 

Conducted by experts who pioneered the use of genetic data to search for the aggressive fish, Mahon and his colleagues' investigation builds upon a growing area of research to find invasive species when they are at low abundance and when they can be potentially managed.

The paper's co-author, Mahon, said, "When we first discovered DNA from Asian carp at the Calumet Harbor and Port of Chicago, we were concerned that Asian carp may already be widespread in the Great Lakes, but because of our collaborations with state and federal partners, we now have a better picture of the Asian carp distribution. We are optimistic that with continued vigilance, it will be possible to prevent Asian carp becoming established in the Great Lakes."

CMU biology faculty and research team introduce new screening method to detect abundance of invasive species in water

March 6, 2013 - Central Michigan University assistant professor of biology Andrew Mahon and a group of researchers from the U.S. Geological Survey (USGS), the University of Notre Dame and The Nature Conservancy have identified a genetic method of surveillance to detect the abundance of invasive species in water.

The study is the first to utilize the common genetic technique known as PCR screening to detect the relative abundance of a particular Asian carp species by testing for residual environmental DNA in water samples.

The findings of their recent study have been published in PLOS ONE, the electronic journal of the Public Library of Science, an open-access publisher of research from all areas of science. Access the article here.

"Our study shows the percentage of DNA positive samplings we find is directly related to the number of that particular species of fish in the water," said Mahon, lead scientist on the study. "This validates the use of eDNA surveillance sensitivity for the detection of multiple species of Asian carps in water systems."

Researchers compared genetic material found in water samples to the number of fish found in a 2.6-mile stretch of river in the Chicago canal system after it was treated with retenone and the fish carcasses were collected.

"Our results showed a positive correlation between the number of genetic samples and the abundance of fish after the canal was treated," said Mahon.

This testing provides for another tool for environmental management agencies to use in determining whether invasive species are present in the water.

"This genetic testing method, along with other traditional options currently being used such as netting, electro fishing, and hook and line sampling, offers an additional tool for detecting invasive species and one more option in the battle against these species getting into our waterways," said Mahon.

USGS Southeast Ecological Science Center scientists Margaret Hunter and Leo Nico are co-authors on the study, providing expertise, genetic samples and information on black carp.

CMU engineering students harvesting pedestrian energy to produce electricity

Electrical panel to provide renewable energy to power temperature display

March 4, 2013 - Central Michigan University engineering students are constructing an electrical panel that will serve as a vibrational energy harvester to create renewable energy for powering a temperature display. The panel, which will be located in the entrance of CMU's Engineering and Technology building, will generate electricity by using the vibrations of pedestrian footsteps as they walk in and out of the facility.

Assistant professor of engineering Tolga Kaya says the student-led project could lead to the development of self-sustainable electric systems to be used in settings highly populated by pedestrians like subway stations or settings that experience heavy vehicle traffic like highways.

"This project is about generating energy through human steps and using that energy to sustain a system without batteries," Kaya said. "This is a small prototype. If this works, similar panels could be installed in train stations and other high traffic areas so that these facilities can be self-sustainable and generate their own energy."

The panel is being constructed as part of a senior design project for engineering students with a budget of $1,500.

The panel is scheduled for completion in April. If the project is a success and the panel is self-sustainable, Kaya imagines it will remain at the entrance of the building in the future.

The project began in the fall with four students conducting the research that would make the second-semester design phase successful. For the students who created the project, there's a genuine interest in the technology that goes beyond the requirements of the course work.

"I have always had an interest in energy harvesters like wind turbines and power dams," said White Lake senior Robert Balma. "It's fun to see something being powered from nothing."

Canton senior Justin Scaparo says the project has been challenging, but the experience he's getting has been very valuable.

"We've had to use a lot of our own research to be innovative in what we're trying to do," Scaparo said. "We're working together, bringing together pieces of our own expertise, to develop new applications using the technology that is out there. It gives me the opportunity to bring what I learn in class to life."

CMU research team sets off to discover new species in Antarctica
Study of invertebrate animals living in one of the most remote regions of the world

January 3, 2013 - A Central Michigan CMU_Antarctica_groupUniversity research team is on a voyage to Antarctica to collect invertebrates in areas of water that have never been explored. On previous research trips to Antartica, assistant professor of biology Andrew Mahon uncovered four new species.

"Because there have been so few people who have been to Antarctica to conduct research, we find new things," said Mahon. "Whether it's a new area where we didn't think a particular species lived or a species that's new to science completely, every time we go we find new things."

Mahon, as well as December 2012 CMU graduate Carlos Coronado and CMU senior Abigail Hollingsworth have joined scientists from Auburn University of Alabama for a six-week journey gathering and analyzing small invertebrate animals in one of the most remote regions of the world.

"From my experience, these trips are life-changing," said Mahon. "You get to see things that nobody has ever seen. You get to go places where nobody else has ever been."

The crew boarded the Nathaniel B. Palmer, a National Science Foundation research vessel, Jan. 1 in Punta Arenas, Chile. During the grant-funded research trip, the scientists will collect invertebrate samples by dropping nets of up to 1,000 feet.

They will be studying DNA and other genetic information from the small animals they gather. Each species will be documented, and samples will be sent to biology labs at CMU for research.

Coronado of Hazel Park is most excited for what they will discover in the nets and the opportunity to see the world.

"We're studying in Antarctica because it's a very unique system," said Coronado. "Not a lot of people get to go there. Particularly this spot where we're going, pretty much no one else has been there."

Hollingsworth of Lexington says she is lucky to have this opportunity as an undergraduate student.

"The kind of opportunities this trip will open up for me and the work experience it will give me... I feel very grateful," said Hollingsworth.
