The Drosophila MAPK p38c Regulates Oxidative Stress and Lipid Homeostasis in the Intestine

The p38 mitogen-activated protein (MAP) kinase signaling cassette has been implicated in stress and immunity in evolutionarily diverse species. In response to a wide variety of physical, chemical and biological stresses p38 kinases phosphorylate various su ...

Integrating landscape genomics and spatially explicit approaches to detect loci under selection in clinal populations

Stéphane Joost

Uncovering the genetic basis of adaptation hinges on the ability to detect loci under selection. However, population genomics outlier approaches to detect selected loci may be inappropriate for clinal populations or those with unclear population structure ...

Sorting genomes with rearrangements and segmental duplications through trajectory graphs

Bernard Moret, Yu Lin, Mingfu Shao

We study the problem of sorting genomes under an evolutionary model that includes genomic rearrangements and segmental duplications. We propose an iterative algorithm to improve any initial evolutionary trajectory between two genomes in terms of parsimony. ...

Learning, Stress and the Role of Personality Profiles in Rats

Maria del Carmen Sandi Perez, Basira Salehi

Stress has been shown to modulate many aspects of physiology and behavior. In particular, substantial work has confirmed that stress is a strong modulator of learning and memory processes. It is more than a century that Yerkes and Dodson have shown that re ...

Tinkering with constraints in the evolution of the vertebrate limb anterior-posterior polarity

Denis Duboule, Jozsef Zakany

Genes belonging to both HoxA and HoxD clusters are required for proper vertebrate limb development. Mice lacking all, or parts of, Hoxa and Hoxd functions in forelimbs, as well as mice with a gain of function of these genes in the early limb bud, have help ...

Digital holographic microscopy for nanometric quality control of micro- optical components

Christian Depeursinge, Tristan Colomb, Etienne Cuche, Jonas Kühn, Florian Charrière

In this paper, Digital Holographic Microscopy (DHM) is presented as a powerful tool for quality control of micro-optical components. It will be shown that not only the single-shot full field-of-view nanometer axial resolution makes DHM an ideal solution fo ...

Early developmental arrest of mammalian limbs lacking HoxA/HoxD gene function

Denis Duboule, Jozsef Zakany

Vertebrate HoxA and HoxD cluster genes are required for proper limb development. However, early lethality, compensation and redundancy have made a full assessment of their function difficult. Here we describe mice that are lacking all Hoxa and Hoxd functio ...

Co-evolving predator and prey robots: Do 'arm races' arise in artificial evolution?

Dario Floreano

Co-evolution (i.e. the evolution of two or more competing populations with coupled fitness) has several features that may potentially enhance the power of adaptation of artificial evolution. In particular, as discussed by Dawkins and Krebs [3], competing p ...

God Save the Red Queen! Competition in Co-Evolutionary Robotics

Dario Floreano

In the simplest scenario of two co-evolving populations in competition with each other, fitness progress is achieved at disadvantage of the other population's fitness. The everchanging fitness landscape caused by the competing species (named the "Red Queen ...

Initiating adaptation to climate change Results from a participatory research project in Switzerland

Romano Tobias Wyss, Cecilia Matasci

Climate change adaptation has become to be a major issue in many tourism dependent areas around the world. While the general importance to put in place adaptation measures is widely recognized by scholars, politicians and practitioners in the field, the pl ...
