Not gone with the wind: Active microscale flight with highly porous bristled wings

Pedro Miguel Nunes Pereira de Almeida Reis, Yuexia Luna Lin

The finesse of sub-millimeter insect flight with comb-like bristled wings raises intriguing questions, not only on fluid-structure interactions (FSI) but also on the mechanical behavior of the underlying, highly porous structures. Farisenkov et al. charact ...

A new Analleucosma Antoine, 1989 from West Africa (Coleoptera, Scarabaeidae, Cetoniinae)

Michele De Palma

The genus Analleucosma Antoine, 1989 is known from northeastern and southeastern Democratic Republic of Congo and a few localities in East Africa; it currently comprises three similar species, all very scarce in collections. Here I describe a new species, ...

Long-lived coupled peeling ballooning modes preceding ELMs on JET

Olivier Sauter, Ambrogio Fasoli, Basil Duval, Stefano Coda, Martinus Gijs, Jonathan Graves, Yves Martin, Duccio Testa, Patrick Blanchard, Bruno Emanuel Ferreira De Sousa Correia

In some JET discharges, type-I edge localised modes (ELMs) are preceded by a class of low-frequency oscillations (Perez et al 2004 Nucl. Fusion 44 609). While in many cases the ELM is triggered during the growth phase of this oscillation, it is also observ ...

Drosophila melanogaster cloak their eggs with pheromones, which prevents cannibalism

Yury Tsybin, Laure Menin, Konstantin Nagornov

Oviparous animals across many taxa have evolved diverse strategies that deter egg predation, providing valuable tests of how natural selection mitigates direct fitness loss. Communal egg laying in nonsocial species minimizes egg predation. However, in cann ...

Inventaire des coléoptères saproxyliques de treize forêts du canton de Vaud

Rita Bütler Sauvain, Gaspard Braulin

In 2017, surveys of saproxylic beetles (dependent on dead wood) were conducted in thirteen forests in the canton of Vaud (Switzerland), including several forest reserves. Interception traps were used to catch a total of 298 species of Coleoptera, including ...

A Drone with Insect-Inspired Folding Wings

Dario Floreano, Stefano Mintchev, Kevin Nicholas Cradock Owen

Flying robots are increasingly adopted in search and rescue missions because of their capability to quickly collect and stream information from remote and dangerous areas. To further enhance their use, we are investigating the development of a new class of ...

Holocene history of Lac des Lauzons (2180 m a.s.l.), reconstructed from multiproxy analyses of Coleoptera, plant macroremains and pollen (Hautes-Alpes, France)

Alexandre Buttler

A 1.70 m core extracted from the Lac des Lauzons, Haut Champsaur, French Alps, at 2180 m altitude, provided a detailed Holocene record of beetles, pollen and plant macrofossils, enabling the reconstruction of local palaeoenvironmental changes during the la ...

The EPFL jumpglider: A hybrid jumping and gliding robot with rigid or folding wings

Dario Floreano, Mirko Kovac, Jean-Christophe Zufferey, Wassim Hraiz, Oriol Fauria Torrent

Recent work suggests that wings can be used to prolong the jumps of miniature jumping robots. However, no functional miniature jumping robot has been presented so far that can successfully apply this hybrid locomotion principle. In this publication, we pre ...

Proteolytic cascade for the activation of the insect toll pathway induced by the fungal cell wall component

Bruno Lemaitre, Ji Won Park

The insect Toll signaling pathway is activated upon recognition of Gram-positive bacteria and fungi, resulting in the expression of antimicrobial peptides via NF-kappaB-like transcription factor. This activation is mediated by a serine protease cascade lea ...
