RNR Research Invention Stops Leaks in Deepwater Wells
(07/19/16) BATON ROUGE, La. – A leading oilfield services company has used an LSU AgCenter invention to help stop fluid from leaking while drilling two deepwater wells off the coast of Vietnam.
TigerBullets – a product created by Qinglin Wu, a professor in the AgCenter School of Renewable Natural Resources – was used in the drilling expedition that Schlumberger Limited began in August 2015. TigerBullets are owned by the AgCenter and licensed to Hole Pluggers, LLC.
TigerBullets are made from plastics, wood scraps, minerals and other additives that are pressed into pellets that stop lost circulation, a major and costly problem when drilling oil wells. Lost circulation refers to the leakage of drilling fluid through cracks in the well. (Photo courtesy of LSU AgCenter)
Lost circulation is typically addressed by pumping material into the well to fill any cracks. When TigerBullets are used, they absorb water and expand, locking them into the fracture to cut off any leaks.
Director of LFPDC Installed as
President of Forest Products Society
Richard Vlosky, Director, Louisiana Forest Products Development Center, LSU AgCenter, was installed as President of the Forest Products Society at the Society’s 70th International Convention in Portland, Oregon on June 29, 2016. The Forest Products Society, the largest international not-for-profit technical association, was founded in 1947 to provide an information network for all segments of the forest products industry.
RNR Grads Featured in Audubon Magazine
The international conservation work of three RNR graduates was featured on the cover of the Summer 2016 Audubon magazine. Jared Wolfe and Luke Powell (former students of Dr. Phil Stouffer), and Kristin Brzeski (former student of Dr. Sabrina Taylor)are doing collaborative research and expeditionary work in the small central African country of Equatorial Guinea – (according to Jared) arguably the country least known to science. The feature article, with "amazing photos" is availabe here. A recent LSU Biology undergraduate, Jacob Cooper, is also using his experiences in undergraduate research programs to contribute to the study.
Waterfowl research returns Ringelman
to his roots
(07/08/16) BATON ROUGE, La. – Kevin Ringelman developed his interest in waterfowl on the plains of Bismarck, North Dakota. Ringelman, an assistant professor and waterfowl ecologist with the LSU College of Agriculture, grew up hunting and learning about ducks in that region.

“My dad spent his entire career working with waterfowl, so it was a natural fit for me,” Ringelman said.
Ringelman received his bachelor’s degree from Cornell University and his doctorate from the University of California at Davis. He joined the LSU College of Agriculture faculty in August 2014.
Ringelman’s research has him returning to his roots while also learning more about waterfowl wintering in Louisiana. “My research is split between issues in Louisiana and breeding grounds in North Dakota,” he said. One of Ringelman’s graduate students is in North Dakota, working on a project to study how fracking in that region is affecting breeding, nesting and duckling survival. Another student is studying lesser scaup diving ducks on Lake Pontchartrain.
Ringelman said the fracking activity in North Dakota may have affected waterfowl in several ways. “They may find quieter places to nest, so we may see fewer pairs. But the fracking may be affecting predators, so nesting success could be higher,” Ringelman said. The effects of fracking could lead to lower duckling survival because brine contamination in wetlands could kill the insects that ducklings eat, affecting their food supply, Ringelman said.
Ringelman also plans to have a doctoral student lead a mottled duck study at Rockefeller Wildlife Refuge in Cameron Parish. They will use radio telemetry to study adult survival during the breeding season.
Being in Louisiana affords Ringelman many research opportunities. “There is no better place than Louisiana to study waterfowl,” he said. Louisiana is an important wintering area for waterfowl, and Ringelman can find other scientists here to collaborate with. He also said Louisiana’s duck-hunting community has been supportive of his research and teaching efforts.
Ringelman teaches three courses in the College of Agriculture School of Renewable Natural Resources: Principles of Wildlife Management, Ecology and Management of Southeastern Wildlife, and Waterfowl Ecology and Management.
He takes some of his classes out in the field for hands-on wildlife activities. Next spring, he plans to have a class help capture ducks using rocket nets and band them. They also will observe veterinarians implant radio transmitters in waterfowl.
“I’m very impressed with the undergraduates here. They want to stay out in the field longer. They are just so enthusiastic about being outside,” Ringelman said “This is very different from the undergraduates I worked with at other universities.”
Ringelman said waterfowl are an important part of Louisiana’s culture and economy. In 2014, 77,000 hunters in Louisiana harvested 1.8 million waterfowl. The total economic benefit to the state was $119 million.

Good News on Zhen--
UPDATE on Zhen: [17 May 2016] Thank you very much for all your help! Zhen is going home today! He still needs time to be fully recovered, but this is already a miracle! The GoFUNDMe account is still open. Any help would still be greatly appreciated!
Zhen Xu, a PhD student in Dr. Jun Xu's lab was the victim of a serious car accident on Sunday, 6 March 2016. A drunk driver driver, going the wrong way on Interstate 10, ran into the car he was in. Zhen was badly injured, and faces a long road to recovery. A GoFundMe account has been established in his name to help to defray the costs associated with travel and housing for his wife and parents, and perhaps some medical expenses. There is not much we can do to help directly at this time but, with your assistance, we can at least help Zhen’s family a little bit financially.
You are encouraged to help with a donation, if you can: Here is the link: GoFundMe: Zhen Xu's Medical Fund. Any little bit would be helpful. Thank you!
