Nanoparticle-based delivery of efflux pump inhibitors and antibiotics to treat mycobacterial infections

In a second edition of TGAC-with-original-authors, we'll discuss Marcussen et al. (2014), a recent Science paper on ancient hybridization of polyploid wheat genomes. The first author Thomas Marcussen will join our discussion, and since Kjetill Jakobsen was involved in the study, we may even have two authors present to answer all our questions. We're switching back to the old meeting time, starting at 1 pm.

This week we'll be discussing a box fresh paper by Tanja Stadler and co-workers in American Naturalist: On Age and Species Richness of Higher Taxa

This week we will discuss another weird group of parasites within the opisthokonts, the myxozoans. They are a strange group of microscopic sized metazoans related to the Cnidaria, and are found in aquatic habitats where they act as parasites of fish, amphibians, reptiles and rarely invertebrates.

This Thursday (6th of November) we will talk more about Illumina sequencing. The paper from last time that compares Illumina with Ion Torrent (Salipante et al. 2014) will be discussed this week.  We also want to discuss a paper that have used the Illumina platform to look at microbial community composition and diversity (Sinclair et al. 2014).

Friday seminar by Thomas Marcussen

”Acoustic startle responses in European sprat (Sprattus sprattus L.) and diploid versus triploid Atlantic salmon fry (Salmo salar L.)”

In a sort of a special edition of the TGAC journal club, we hope to finally find out whether Thor Heyerdahl was right after all with his claims regarding early contact between the cultures of South America and Easter Island, whether his Kon-Tiki expedition in 1947 was just a fun cruise across the Pacific without any scientific substantiation, or whether genomic data actually supports his ideas. We will find the answers in the very recent paper by Moreno-Mayar et al. (2014), which just came out in Current Biology and comes with a commentary in Science. Four of the authors are working at the University Hospital here in Oslo, and at least two of them will join our discussion!

As there will be a CELS meeting this Tuesday at 1 pm, the TGAC discussion will be earlier than usual, at 11 am.

An investigation of the functional role of the MADS-box γ and MADS-box α type I transcription factors: AGAMOUS-LIKE 28 and AGAMOUS-LIKE 36

Late lunch talk by Robin Cristofari

This week, we read a paper from Ecology Letters by Barnagaud et al. 2014.

This Friday we will discuss this review paper about the fascinating and numerous microsporidian parasites.

PROGRAM (pdf: This is an excerpt from the booklet that will be handed out at the conference)

Friday seminar by Charles Krebs

This week we will read a paper on competition in bryozoans by Svensson and Marshall 2014: "Limiting resources in sessile systems: food enhances diversity and growth of suspension feeders despite available space".

We feel that it's time to find out about the Pairwise Sequential Markovian Coalescent and it derivations. How does it magically infer demography from single genomes? Why does the original author recommend other tools? Why do all these demography plots look the same? And can I use it for my data? Once more, we'll need more than one paper to find out. We'll focus on the first publication to present the PSMC, Li & Durbin (2011) in Nature, but we invite participants with a bit of extra time to check out and report on updates on the method, which were published by Schiffels & Durbin (2014) in Nature Genetics, and by Harris et al. (2014) on arXiv.

A collection of recent CEES publications

”Protist diversity across a marine - freshwater gradient with a special focus on the X-cell parasite”

"Effekter av miljøgifter på torsk (Gadus morhua) fra indre Oslofjord"

This tuesday, we'll discuss genome resequencing and hybrid origin of pig populations, as recently reported by Bosse et al. (2014) in Molecular Ecology, Bosse et al. (2014) in Nature Communications, and Ramírez et al. (2014) in Heredity. We'll focus on the Molecular Ecology paper, but try to provide a brief summary of the other two studies as well.

Mattis B. Wigestrand: Optogenetics - Manipulating animal behavior with light

Friday seminar by Horacio Schneider

This week we read Wagner and Marcot's "Modelling distributions of fossil sampling rates over time, space and taxa: assessment and implications for macroevolutionary studies" in MEE.

As we are starting to worry about bias in branch lengths when phylogenetic approaches are used with genomic data, we'll have a look at McGill et al. (2013), which discusses the influence of minor allele frequency thresholds on estimates of demography.

Open seminar at the House of Literature

Friday seminar by Lars Werdelin

Effects of steroid hormones on the expression of Ca2+ activated K+ channels in in vitro pituitary cells of Atlantic cod (Gadus morhua)

Come join a discussion on "A novel Bayesian method for inferring and interpreting the dynamics of adaptive landscapes from phylogenetic comparative data" by Uyeda and Harmon fresh from Sys Bio.

As a follow-up to our discussion on genomic islands of speciation two weeks ago, we'll continue along the same lines with a recent paper by Ruegg et al. (2014) that came out recently in Molecular Evolution.

Late lunch talk by Walter Salzburger.

”Fine-scale spatial structure of root-associated fungi within a single plant root system”

"Exposure of juvenile Atlantic cod (Gadus morhua) to water-accommodated fractions of Arabian light crude oil: Biotransformation and DNA damage"

Friday seminar by Andrea Waeschenbach from Natural History Museum, London, UK

Immune Cell Composition in Human Non-Small Cell Lung Cancer

In this weeks edition of the TGAC journal club, we'll focus on African cichlid fishes, and the "genomic substrate" of their adaptive radiation: The paper by Brawand et al. (2014), was published last week in Nature.

This week in the macroevolution journal club we will read a paper: "Calibrating the Tree of Life: fossils, molecules and evolutionary timescales", Forest, 2009.

”Testing Species Boundaries in the Staphylinid Beetle Genus Mocyta (Insecta, Coleoptera, Staphylinidae)”

Studies of ATF7IP as a novel interaction partner of c-Myb - epigenetic repressor or co-activator?

MBD proteins - possible links between DNA methylation and histone modification in Arabidopsis thaliana

The role of LBD proteins in floral organ abscission

We restart the TGAC+CELS journal club series with a discussion of a recent review (Cruickshank & Hahn 2014) on genome divergence between closely related species. A substantial paper, but a highly relevant one, also for our friends from the speciation journal club!

This week we discuss a new book chapter by Nunn and Zhu on using "Phylogenetic Prediction to Identify 'Evolutionary Singularities'"  with our visitor Matt Pennell.

Late lunch talk by Matt Pennell.

Mini-seminar in connection with the conferment of an honorary doctoral degree awarded to Prof. Eske Willerslev by the University of Oslo. Sign up!

The author, philosopher and biologist Massimo Pigliucci will give a lecture on: "The relationship between science and philosophy". Hopi Hoekstra from Harvard University will tell us about: "Digging for genes that affect behavior". The Kristine Bonnevie lectures on evolutionary biology is part of the University’s annual celebration.
