Maruska's Research Published in General and Comparative Endocrinology
The Maruska Lab has a new paper out showing that the mTOR kinase is involved in reproductive
plasticity in male cichlid fish as they rise in social status to dominance - some
similarities to mammals, and role in male reproduction may be conserved across vertebrates. Read the paper in General and Comparative Endocrinology.
The Kelly Lab's Research Featured on the Cover of Molecular Ecology
Lab member and Graduate student Joanna Griffiths asks whether physiological and transcriptomic responses to acidification differ among corals from different upwelling regimes. Ocean acidification (OA), the global decrease in surface water pH from absorption of anthropogenic CO2, may put many marine taxa at risk. However, populations that experience extreme localized conditions, and are adapted to these conditions predicted in the global ocean in 2,100, may be more tolerant to future OA. By identifying locally adapted populations, researchers can examine the mechanisms used to cope with decreasing pH. Read the paper in Molecualr Ecology.

Three Graduate Degrees, Meditation and Drug Repurposing Research: It’s All a Balancing Act
Take it from someone who’s earned a Ph.D. and two masters degrees all while conducting cutting-edge drug repurposing research: knowing how to handle your stress is important. Recent graduate Misagh Naderi is involved in research to combat rare or orphan diseases. By using an online database of rare disease research, he and his team have created a system to repurpose existing FDA-approved drugs to treat orphan diseases. Since 2011, Misagh has taught the longest running student-lead program at the International Culture Center (ICC): Meditation at LSU. Misagh had been involved with mediation long before he came to LSU, and he also enjoys yoga, running, rock climbing, listening to audiobooks and making visually striking scientifically inspired graphics. We asked Misagh to tell us about his research and how he was able to keep his stress at bay while earning his two latest degrees. Read More
Being a Student Can Be Stressful. Science Can Help.
There’s no doubt about it – being a student can be stressful. From scheduling classes and waitlists, to taking exams, to waiting on grades, to lining up a summer job, to managing roommate drama, to making sure you on are track to graduation, to deciding what you will “do with your life” when you finish school, stressful events lurk in every corner. No matter how prepared you are, there’s always going to be a failed grade, a missed deadline or a miscommunication with a professor here and there.
But what is stress? Stress can be defined as a behavior or physiological change in an individual in response to a real or perceived stressor. Not all of us perceive the same stressors in the same way, however, meaning that one person may deal with a stressful event and remain happy and healthy, while another may become anxious and ill as a result.

Larkin Lab featured in a Plant Physiology Magazine Cover Story
In work featured on the cover of the August 2018 issue of Plant Physiology, Narender Kumar and colleagues from the Larkin lab have identified the functions of specific amino acid motifs that are shared among SIM and related cell cycle regulators. Dr. Kumar and colleagues have identified sequences in the SIM protein that are important in allowing SIM to bind to and inhibit the function of proteins called cyclin-dependant kinases that would normally promote cell division, as well as sequences that are essential for the SIM to enter the cell's nucleus. The cover photo is a scanning electron micrograph taken by Dr. Kumar in LSU's Shared Instrument Facility showing a multicelllular leaf hair in a mutant lacking a functional SIM protein. Dr. Kumar is now doing postdoctoral work on root development in the lab of Dr. Anjali Iyer-Pascuzzi at Purdue University."

Purple, Gold and...Green?
Researchers at LSU recently discovered a group of lizards in New Guinea that have lime-green blood. Prasinohaema are green-blooded skinks, a type of lizard, that somehow thrive with what would be toxic human levels of biliverdin, a green bile pigment. We humans do have some biliverdin in our blood, but these lizards have levels of biliverdin 40 times higher than those in humans.

Study Links Recovery of Oiled Marsh with Return of Salt Marsh Vegetation
Emeritus Professor John Fleeger's research on recovery from the Deepwater Horizon Oil Spill is featured on the Gulf of Mexico Research Initiatives website. The article details the response of the benthic community in oiled sediments in Louisiana salt marshes. The research team in a recent publication with Fleeger as the lead author found that many benthic invertebrates recovered in about 3 years and that this recovery was strongly associated with the recovery of the principal marsh plant species Spartina alterniflora. However some invertebrates are still recovering from the spill after 4 years. Fleeger and the research team will continue to investigate these marsh sites to determine when all benthic species might recover and when the marsh will regain its full range of ecological services.
