A kinase and a phosphatase: molecular basis of inherited Parkinson’s disease

Activating mutations in LRRK2 kinase cause Parkinson’s disease and activated LRRK2 phosphorylates a subset of Rab GTPases. We have discovered that Rab phosphorylation blocks primary cilia formation in specific neurons and astrocytes in the nigrostriatal circuit that are important for dopaminergic signaling in Parkinson's disease. This lecture will provide an update on our studies using purified LRRK2 and its counteracting PPM1H phosphatase to understand how the proteins become localized and activated on membrane surfaces. In addition, work will be presented related to the consequences of LRRK2 mutation for neurons and astrocytes in the dorsal striatum of mice and humans.

Did you know that for some very special materials, when you shine light on them they will cool down? Optical refridgeration is not a very well known phenomena but it can cool materials down to temperatures below 100K! In this talk we will discuss the optical trapping of nanoparticles AND the bulk cooling of them using optical means.

Title: Lectures on Capacities Speaker: Professor Daniel Spector, National Taiwan Normal University

Lecture 1 Tuesday, June 20 10 am Title: Riemann and Lebesgue Integration Abstract: The Riemann integral is perfectly suited for consideration of volume, surface area, arc length, and integration of functions in classical analysis - when the sets in question are smooth and the functions in question continuous. In this talk, we introduce these ideas and explain the progression from Riemann integration to Lebesgue integration, emphasizing in particular the powerful tools one obtains from this construction. Lecture 2 Wednesday, June 21st 10 am Title: Capacitary Integration Abstract: The Lebesgue integral provides one with a satisfactory tool for many purposes in mathematical analysis. Yet in the modeling of natural phenomena, with the introduction of partial differential equations, integrals which are not Lebesgue integral makes a prominent appearance - capacitary integrals. In this talk we discuss this motivation for capacitary integration, with examples, explain the differences with Lebesgue integration, and show the usefulness of these non-standard objects. Lecture 3 Thursday, June 22nd 10 am Title: Capacitary Sobolev Inequalities and Applications Abstract: The study of capacities and Capacitary Sobolev Inequalities is now more than half a century old, and yet there are still a number of open research questions to investigate concerning them. In this talk we discuss in more detail Capacitary Sobolev inequalities with an emphasis on a subject with the most recent activity - Capacitary Sobolev Inequalities around L1. Open problems will be mentioned.

This is a series for those who are either currently in the midst of a job search for an academic position and would like to improve their existing materials, or for anyone who plans to engage in a job search on the academic market in the future. The series will cover the most common application materials required for academic jobs, as well as an introduction to the process of searching for a job itself.

Are you interested in making your presentations more memorable? Would you like to participate in a global event and give a speech on the big stage?

The Falling Walls Lab events and similar 3min pitch competitions give young researchers the chance to impress the world with their work.

In this briefing session Moe Atwa (recent OIST Graduate; Falling Walls Lab Sendai 2023 winner and global finalist) and Jonas Fischer (Academic Coordinator for Visiting Programs; Falling Walls 2020 Top 10 Winner) will talk about their experiences at the Falling Walls Lab Sendai and the global finals in Berlin. In addition, Izabela Porebska and Theodoros Bouloumis of OIST’s Orators Club will share their experiences from Falling Walls, “3 Minute Thesis”, and similar events.

The main part of the session will be on general methods and tips to make your presentations more engaging.

Finally, we will explain how to apply for the Falling Walls Lab Tokyo 2023 on July 25th, which will be co-hosted by OIST, and the planned practice sessions in June and July. However, there is no need to apply for the actual Falling Walls Lab in order to join this briefing session. Feel free to join if you are interested in the topic in general, or thinking about joining the Falling Walls Lab competition or a similar event in the future. Open to all students, postdocs, and employees at OIST.

Generation of entanglement from mechanical rotations. Is it possible to use the movement of massive objects to generate quantum entanglement? If this proves to be possible - what consequences would it have for our understanding regarding quantum mechanics and how it relates to space and time? Come to this talk by thoeretician Dr Toros, from Scotland - to hear how he proposes to do it and what might be the consequences!

Abstract Population genetics and phylogenetics are two main subfields of evolutionary genetics. The former investigates the genetic variations among populations within a species while the latter focuses on reconstructing phylogeny of many species using genetic data. In this presentation, I will present my previous work on the population genetics of an alpine ground beetle, Nebria ingens complex, in the Sierra Nevada in California and my current work on the deep evolutionary history of species radiation of Lepidoptera. In the alpine ground beetle study, I used genome-wide variants to characterize the population structure and demographic history. I found that the glacial refugia was in the low-elevation drainage basins of Sierra Nevada during the last glacial maximum, followed by the postglacial recolonization to the current high-altitude alpine zone. I also used genome-wide association approaches to identify the genes putatively associated with the postglacial elevational range shift, local adaptation to the heterogeneous environments, and the morphological variations. For the study of Lepidoptera species radiation, I use published high-quality lepidopteran genomes to explore the genomic evidence related to rapid diversification of modern lepidopteran lineages. The preliminary results suggest that the gene evolution involving host plant detection, phytocompound detoxification, and protein digestion play crucial roles in species diversification along with the Angiosperm radiation. Finally, I will provide my personal perspective on connecting population genetics (microevolution) and phylogenetics (macroevolution) for a more thorough understanding of evolutionary processes.

About Dr. Yi-Ming Weng: Yi-Ming was born and brought up in Taiwan. He graduated from National Chung-Hsing University for bachelor’s and master’s degrees in Entomology department. He is interested in insect biodiversity and evolution in general. For his master thesis, he studied phylogeography of alpine ground beetles in Taiwan, looking for sharing evolutionary history between the alpine ground beetle species with similar ecological niche and geographical distribution. Yi-Ming started his PhD carrier in the University of Wisconsin-Madison in 2017. He worked with Professor Sean Schoville to further study the evolutionary history of alpine ground beetle from the Sierra Nevada in California using genomic data. By the time he started to develop his skillsets in bioinformatics and genomics. Now Yi-Ming is working with Professor Akito Kawahara in the University of Florida as a postdoctoral researcher studying evolutionary genomics of Lepidoptera.

Despite Yi-Ming has been working mostly with computers for his bioinformatics analyses, he is most interested in outdoor activities and direct observation of insects. He believes that good biological questions usually come from the field, and stepping out to touch the insects gets the best inspiration.
