MicroRNAs in Metastasis

Advent er tiden for å lage småkaker. Men hva er det som egentlig skjer med eggehvitene når de bankes opp, stekes og blir til deilige julekaker? Dette forteller Anja Røyne om i Forskerfrokost. Hun er postdoktor på Fysisk Institutt. Kanskje blir det smaksprøver også?

From Pluripotency to Definitive Endoderm: Delineating the Signalling Events of Endoderm Specification in Human Pluripotent Stem Cells

John Quigg, Arizona State University (Tempe), USA, will give a talk with title "The Pedersen rigidity problem".

University of Abstract: If \alpha is an action of a locally compact abelian group G on a C*-algebra A, Takesaki-Takai duality recovers (A,\alpha) up to Morita equivalence from the dual action of \widehat{G} on the crossed product A\rtimes_\alpha G. Given a bit more information, Landstad duality recovers (A,\alpha) up to isomorphism. In between these, by modifying a theorem of Pedersen, (A,\alpha) is recovered up to outer conjugacy from the dual action and the position of A in M(A\rtimes_\alpha G). Our search (still unsuccessful, somehow irritating) for examples showing the necessity of this latter condition has led us to formulate the "Pedersen rigidity problem". We present numerous situations where the condition is redundant, including G discrete or A stable or commutative. The most interesting of these "no-go theorems" is for locally unitary actions on continuous-trace algebras. This is joint work with Steve Kaliszewski and Tron Omland.

Late Lunch Talk by Claudio Ottoni, CEES

Riccardo De Bin (Department of Mathematics, University of Oslo) will give a seminar in the lunch area, 8th floor Niels Henrik Abels hus at 14:15.

Framed correspondences were invented and studied by Voevodsky in the early 2000-s, aiming at the construction of a new model for motivic stable homotopy theory. Joint with Ivan Panin we introduce and study framed motives of algebraic varieties basing on Voevodsky's framed correspondences. Framed motives allow to construct an explicit model for the suspension P¹-spectrum of an algebraic variety. Framed correspondences also give a kind of motivic infinite loop space machine. They also lead to several important explicit computations such as rational motivic homotopy theory or recovering the celebrated Morel theorem that computes certain motivic homotopy groups of the motivic sphere spectrum in terms of Milnor-Witt K-theory. In these lectures we shall discuss basic facts on framed correspondences and related constructions.

Stereolithography - A Powerful Tool to Create almost Everything

Stereolithography or "SLA" printing is a powerful and widely used 3D printing technology for creating prototypes, models, and fully functional parts for production. This additive manufacturing process works by focusing an ultraviolet (UV) laser onto a vat of liquid resin. Layer by layer formation of a polymeric network allows printing parts that are almost impossible to create with other processes.At Formlabs, a startup that originated out of the MIT Media lab in 2011, we work on all aspects of SLA printing; we develop and manufacture 3D printers, resins, and software. In this talk, I will give a detailed overview of the printer technology, the chemistry of the materials, and how to use SLA for lots of exciting applications.

This Friday the journal club will discuss a paper by Simon et al. (2016): "High evolutionary constraints limited adaptive responses to past climate changes in toad skulls".

Effective population size is an important concept in evolutionary biology, providing information about genetic variability, inbreeding and the efficiency of directional selection. Despite its obvious relevance, it has rarely been discussed in the context of fishery-induced selection.  

This thursday, at the Speciation Journal Club, we will discuss a paper entitled "Neighboring genes for DNA-binding proteins rescue male sterility in Drosophila hybrids" by Lienard et al. in PNAS (2016)
