The mesoglea buffers the physico-chemical microenvironment of photosymbionts in the upside-down jellyfish Cassiopea sp

Anders Meibom, Niclas Heidelberg Lyndby, Michael Kühl

IntroductionThe jellyfish Cassiopea has a conspicuous lifestyle, positioning itself upside-down on sediments in shallow waters thereby exposing its photosynthetic endosymbionts (Symbiodiniaceae) to light. Several studies have shown how the photosymbionts b ...

A Long Time Ago in a Galaxy Far, Far Away: A Candidate z similar to 12 Galaxy in Early JWST CEERS Imaging

Michaela Hirschmann

We report the discovery of a candidate galaxy with a photo -z of z similar to 12 in the first epoch of the James Webb Space Telescope (JWST) Cosmic Evolution Early Release Science Survey. Following conservative selection criteria, we identify a source with ...

Linking a mutation to survival in wild mice

Jeffrey David Jensen, Matthieu Foll, Susanne Petra Pfeifer, Stefan Jean Laurent

Adaptive evolution in new or changing environments can be difficult to predict because the functional connections between genotype, phenotype, and fitness are complex. Here, we make these explicit connections by combining field and laboratory experiments i ...

Selective Peptide-Mediated Enhanced Deposition of Polymer Fragrance Delivery Systems on Human Hair

Harm-Anton Klok, Kemal Arda Günay

The deposition of fragrance delivery systems onto human hair from a shampoo formulation is a challenging task, as the primary function of shampoo is to cleanse the hair by removing primarily hydrophobic moieties. In this work, to tackle this challenge, pha ...

Bioinspired Selective Surface Deposition of Fragrance Delivery Systems

Kemal Arda Günay

The perception of pleasantness in many of the consumer goods is provided by volatile chemical compounds called fragrances. While the volatility of fragrances is essential to provide a pleasant olfactory response, it presents at the same time a technologi ...

De-anonymizing Genomic Databases Using Phenotypic Traits

Jean-Pierre Hubaux, Joachim Ludovic Hugonot, Kévin Clément Huguenin, Erman Ayday, Mathias Jacques Jean-Marc Humbert

People increasingly have their genomes sequenced and some of them share their genomic data online. They do so for various purposes, including to find relatives and to help advance genomic research. An individual's genome carries very sensitive, private inf ...

Coat color dilution in mice because of inactivation of the melanoma antigen MART-1

Friedrich Beermann, Iraz Toprak Aydin

Melanoma antigen recognized by T cells 1 (MART-1) is a melanoma-specific antigen, which has been thoroughly studied in the context of immunotherapy against malignant melanoma and which is found only in the pigment cell lineage. However, its exact function ...

Dynamic hair capture

Mark Pauly, Hao Li

The realistic reconstruction of hair motion is challenging because of hair’s complex occlusion, lack of a well-defined surface, and non-Lambertian material. We present a system for passive capture of dynamic hair performances using a set of high-speed vide ...

Key roles for transforming growth factor beta in melanocyte stem cell maintenance

Friedrich Beermann

Melanocyte stem cells in the bulge area of hair follicles are responsible for hair pigmentation, and defects in them cause hair graying. Here we describe the process of melanocyte stem cell entry into the quiescent state and show that niche-derived transfo ...

Cell culture imaging using microimpedance tomography

Philippe Renaud, Olof Pontus Linderholm

We present a novel, inexpensive, and fast microimpedance tomography system for two-dimensional imaging of cell and tissue cultures. The system is based on four-electrode measurements using 16 planar microelectrodes (5 mum x 4 mm) integrated into a culture ...

Notch1 and Notch2 receptors influence progressive hair graying in a dose-dependent manner

Freddy Radtke, Friedrich Beermann

The Notch signaling pathway is involved in diverse biological processes such as cell fate decisions or stem cell maintenance. In this study, we assessed the role of this pathway for melanocyte development and hair pigmentation using RBP-Jkappa, Notch1, and ...

Color correction of uncalibrated images for the classification of human skin color

Sabine Süsstrunk, Joanna Marguier

Images of a scene captured with multiple cameras will have different color values due to variations in capture and color rendering across devices. We present a method to accurately retrieve color information from uncalibrated images taken under uncontrolle ...

Assessing human skin color from uncalibrated images

Sabine Süsstrunk, Joanna Marguier

Images of a scene captured with multiple cameras will have different color values due to variations in color rendering across devices. We present a method to accurately retrieve color information from uncalibrated images taken under uncontrolled lighting c ...

Model surfaces for human hair : screening perfumes and surfactants

The thesis describes the development of surfaces that model the surface of human hair in order to characterize the adsorption of detergents and perfumes. Three types of model surfaces were investigated consisting of (i) a self-assembled monolayer of protei ...
