A Biohybrid Superorganism - Investigating honeybees' collective behaviors via interactive robotics

Social insects, such as ants, termites, and honeybees, have evolved sophisticated societies where the collaborative efforts of "simple" individuals can lead to the emergence of complex dynamics. The reliance of each organism on the collective is so great t ...

Species conservation in the face of global environmental changes: surface-based modelling of geo-environmental data to identify vulnerable populations

Estelle Rochat

Human activities are resulting in many land-use changes, particularly due to urbanisation and intensification of agricultural practices. Because of these changes, in addition to climate change, many species are facing habitat degradation. In order to avoid ...

Catalytic valorization of the acetate fraction of biomass to aromatics and its integration into the carboxylate platform

Jeremy Luterbacher, Masoud Talebi Amiri, Ydna Marie Questell-Santiago, Benjamin Pierre Le Monnier, Jher Hau Yeap, Bartosz Rozmyslowicz, Ahmed Mohamed Ibrahim Elkhaiary

In many plant species, the acetate fraction is the fourth most prominent fraction by weight after cellulose, hemicellulose and lignin, and can be easily extracted as a single stable molecule, acetic acid, at high yields. Despite this, upgrading the acetate ...

Impact of the urbanization process on connectivity and genetic diversity - a spatially explicit simulation approach

Stéphane Joost, Estelle Rochat, Ivo Widmer

Urbanization leads to fragmentation, degradation or loss of natural environments and reduces connectivity between remaining habitat patches. This affects dispersal and establishment of species and their genes and might have adverse effects on biodiversity ...

Biomimetic Pieris rapae’s Nanostructure and Its Use as a Simple Sucrose Sensor

Philippe Renaud, David Vincent Bonzon, Rodrigo Martinez Duarte

iomimetics often provides efficient ways to create a product incorporating novel properties. Here we present the replication of the Pieris rapae butterfly optical structure. This butterfly has white wings with black spots. The white coloration is produced ...

Optofluidic modulator based on peristaltic nematogen microflows

Demetri Psaltis, Andreas Vasdekis, Julien Cuennet, Luciano De Sio

Nematogens rotate by the application of external fields, thereby enabling optical modulation. This principle has had a profound impact on our daily lives through the plethora of liquid-crystal displays in use around us(1,2). However, the wider use of nemat ...

Conserved oviposition preferences in alpine leaf beetle populations despite host shifts and isolation

Anthony Christopher Davison

Choosing the plant on which to lay their eggs is the last act of care that most female herbivorous insects bestow upon their offspring. These decisions play a pivotal role in insect–plant interactions, placing host preference under strong selection and ...
