Is There a Doctor in the House?

Tue, 08/13/2019 - 05:25

...there is now!

We're happy to report that Ph.D. candidate Anthony Auletta successfully passed his dissertation defense yesterday! Congratulations to the newly-minted Dr. Auletta!

Anthony recently began his new position as Lecturer of Insect Biology at the University of Florida Department of Entomology & Nematology. While it is bittersweet to see him go after six years in the lab, we are very excited for him as he begins this new chapter of his career and we wish him all the best in his future endeavors!

New Publication: Catecholaminergic Neurons in the Spider CNS

Catecholaminergic neurons in the wolf spider

We are very excited to announce a new publication, hot off the presses at the Journal of Comparative Neurology! The full citation is below:

Auletta ARue MCPHarley CM, & Mesce KA. 2019. Tyrosine hydroxylase immunolabeling reveals the distribution of catecholaminergic neurons in the central nervous systems of the spiders Hogna lenta (Araneae: Lycosidae) and Phidippus regius (Araneae: Salticidae). Journal of Comparative Neurology 2019: 1-20. https://doi.org/10.1002/cne.24748

Congratulations to lead author, Ph.D. candidate Anthony Auletta, as well as his co-authors: former lab manager Mara C.P. Rue, former postdoc Cindy Harley, and PI Karen Mesce! They have been working on this one for a long time, and are all very excited to share the results with you. This paper is the first description of catecholaminergic (e.g. dopaminergic and adrenergic) neurons in the central nervous system of any arachnid species, and forms a core component of Anthony's doctoral dissertation.

The full text of the article is available online now, via JCN's "Early View." Please go check it out!

Anthony Says, "Later, Gator!"

Gator!

This week, we bid a fond farewell to Ph.D. candidate Anthony Auletta, as he heads down to Gainesville, FL to begin his new position as Lecturer of Insect Biology at the University of Florida Department of Entomology & Nematology. As a member of the teaching faculty at UF, Anthony will develop and teach a variety of entomology courses, as well as advise undergraduate students and coordinate CUREs (course-based undergraduate research experiences). It is a perfect fit for Anthony, who is passionate about entomology and undergraduate education, and we wish him the very best in Florida!

Anthony will be back to visit Minnesota next month, to formally defend his Ph.D. dissertation.

Anthony Receives CFANS Teaching Award

Yay for great teachers!

Congratulations to Ph.D. Candidate Anthony Auletta, who was recently selected to receive the Graduate Assistant Teaching Award from the College of Food, Agriculture, & Natural Resource Sciences (CFANS)! This prestigious award, which includes a $1500 prize, is given annually to one graduate student in CFANS who has demonstrated excellence in undergraduate teaching and education. During his time at the University of Minnesota, Anthony has taught in five different entomology courses, and has made strong contributions to the undergraduate and graduate programs in the Department of Entomology. He has a strong interest and background in pedagogy, and will be pursuing a career in undergraduate entomology education after he graduates later this year. Congratulations, Anthony, on this well-deserved recognition!

Anthony will formally receive the award at the CFANS Spring College Assembly, which will take place on Tuesday, May 7th from 9:30 am–12:00 pm in 105 Cargill.

Anthony presents at SICB 2019

Tampa!

 

SICB

Ph.D. Candidate Anthony Auletta is kicking off the new year in sunny Tampa, FL, at the 2019 Annual Meeting of the Society for Intregrative & Comparative Biology (SICB). The meeting will take place in the Tampa Convention Center from January 3-7th. If you'll be in attendance, please come check out Anthony's poster, which details the latest and greatest research he's done as part of his doctoral dissertation:

Auletta A, Mesce KA. 2019. An examination of biogenic amines in nervous system of the scorpion Centruroides sculpturatus (Scorpiones: Buthidae) provides insight into the evolution of neuromodulatory systems in the Arthropoda. 

And, of course, from all of us here in the Mesce Lab, have a safe, happy, and productive new year!! We look forward to all of the wonderful things to come in 2019!

Anthony wins ESA Poster Prize

Tue, 11/20/2018 - 13:45

Congratulations to Ph.D. candidate Anthony Auletta, who won Second Place in his poster section at the 2018 Annual Meeting of the Entomological Society of America in Vancouver!

His poster, A window into the past: evidence for an ancient tripartite dopaminergic, adrenergic, and octopaminergic signaling system in the Chelicerata, co-authored with PI Karen Mesce, showcased our latest research into the evolution neuromodulatory systems in scorpions (and other arachnids).

Congratulations, Anthony!

Representing at SFN and ESA 2018!

Mon, 10/29/2018 - 13:30

We're taking this show on the road! That's right-- this November, you'll have the chance to learn about all of the great research we've been doing at not one, but two conferences!

SFN 2018
To all of our neuroscience friends, we hope that we will see you at the Society for Neuroscience Annual Meeting this year from November 3-7 in San Diego, CA! PI Karen Mesce and Ph.D. Candidate Morgan Newhoff will both be in attendance and presenting posters on their work! If you're at SFN this year, please stop by the poster hall on Sunday the 4th and say "hi!" Full poster citations are below:

Newhoff M, Smith C, Ebbini E, Mesce KA. 2018. Low intensity ultrasound reversibly inhibits single neuron firing in a tractable invertebrate model.

Mesce KA, Bigelow AW, Puhl JG. 2018. Reorganization of proprioceptive inputs facilitates locomotor recovery after injury to the CNS.

ESA 2018
And if you're more on the entomology side of the spectrum, we look forward to seeing you at the Entomological Society of America Annual Meeting from November 11-14 in Vancouver, BC! Ph.D. Candidate Anthony Auletta will also be there, and will present a poster on his dissertation research. Come learn more about it in the poster session on Monday the 12th! His full poster citation is below:

Auletta A, Mesce KA. 2018. A window into the past: evidence for an ancient tripartite dopaminergic, adrenergic, and octopaminergic signaling system in the Chelicerata.

In addition, Anthony will also be participating in the ESA Student Debates this year, alongside fellow entomology graduate students Anh Tran, Edwin Benkert, and Dylan Tussey. Their debate will take place on Tuesday the 13th at 3:00pm. Come by and cheer on their team!

New Faces in the Mesce Lab!

Wed, 10/17/2018 - 12:00

We have two new faces joining us in the Mesce lab this fall! 

Emiliya (Emma) Bayko is a new undergraduate researcher in the lab, who will be working with us on our ongoing project to uncover the mechanisms of recovery following nerve cord injury in the leech. Emma comes to us from Metropolitan State University, where she has previously worked with Asst. Prof. Cindy Harley (former postdoctoral fellow in the lab)! We look forward to working with Emma this semester, as well as our continued collaboration with Cindy on this project!

Also joining us this semester is Radhika (Rads) Edpuganti. Rads is current undergraduate student in the Neuroscience program here at the U of M, and will be working with us over the next year on a variety of projects, including the leech revovery project, our arachnid neurobiology project, and the ultrasonic neuromodulation project. We are very excited to have Rads onboard!

Welcome, welcome, Emma and Rads!

Karen is the New ISN President!

Mon, 10/08/2018 - 17:30

Karen Mesce
The votes are in, and we are very excited to announce that our very own Dr. Karen Mesce will be the new president of the International Society for Neuroethology! Karen has a long and rich history of service to the ISN, as the current treasurer and a former secretary of the society, and we think that she is the perfect person for this role. We look forward to the many wonderful things that she will accomplish during her presidency!

Karen begins as president-elect for the 2018-20 term, after which she will officially take over as president for the 2020-22 term, which includes the 2020 International Congress of Neuroethology in Lisbon, Portugal.

Congratulations again, Karen, on your well-deserved victory!
