New paper details the negative impact of Chaoborus on lake ecology
June 20, 2017

Phantom midge larvae Chaoborus spp. are prevalent in eutrophic lakes globally. The insects diurnally migrate, and dwell in the sediments during the day - bioturbating the sediments. We found that their respiration can significantly increase sediment and water column oxygen demand. Furthermore, the m…

New paper in Nature Communications : the link between CAMP and the end-Triassic mass extinction
May 31, 2017

New high-precision U-Pb ages of zircon from mafic igneous rocks of the Central Atlantic Magmatic Province (CAMP) were published in a new article in Nature Communications by Davies et al. The study reveals that part of the sills, dykes and intrusions of the CAMP predate the end-Triassic extinction ev…

Mineral resources: exhaustion is just a myth
May 31, 2017

In contrast to recent articles announcing that deposits of mineral raw materials (copper, zinc, etc.) will be exhausted within a few decades, an international team including Lluís Fontboté (UNIGE) has shown that the resources of most mineral commodities are sufficient to sufficient to supply countle…

New Article in Nature Communications
May 29, 2017

The article, co-authored by Dario Ventra (Basin Analysis Group, UNIGE), challenges the long-held view that pre-vegetation fluvial channels on Earth’s Proterozoic landscapes would have differed substantially in morphology from Phanerozoic channels. Outcrop and remote-sensing datasets show that well-d…

New paper in Geology: sea level changes and carbon isotopes
May 23, 2017

Sebastien Castelltort, Louis Honegger and colleagues from Lausanne, Austin and Barcelona found that carbon isotopes on the continental slope of the Eocene Pyrenean foreland basin are in remarkable correlation with eustatic sea level signals recorded independently on the New Jersey margin. This revea…

May 18, 2017

The SETAC Young Scientist Award 2017 for best poster presentation was attributed to Amandine Laffite at the SETAC Europe 27th Annual Meeting held in Brussels between 7 and 11th of May 2017. Amandine is a PhD student working on the epidemiology of antibiotic resistance in Sub-Saharan African Countri…

New Paper in Water Research
April 27, 2017

In this study, the possible antibiotic mechanisms prevailing in Pseudomonas spp., isolated from aquatic ecosystems under tropical (30-37°C, from Congo and India) and temperate (10°C, from Switzerland) climatic conditions was investigated. The conjugative transfers of antibiotic resistance plasmids o…

A Study Investigating the Distribution of Organic Aerosol in the North Atlantic Ocean Published in Nature Scientific Reports
April 11, 2017

This study resulting from the DeepWater Expedition and a collaboration between scientists of the GAP, ISE and FOREL linking the distribution of aerosols with surface ocean dynamics has just been published in Nature Scientific Reports.

New Paper in Scientific Reports
April 11, 2017

We discovered that the fly larvae Chaoborus spp. utilize methane in lake sediments to propel themselves. The larvae live in the sediment, and migrate to the surface to feed at night via this “gas lift”, saving substantial energy. Consequently, they liberate this important greenhouse gas to the surfa…

Modelling copper endowment of porphyry copper deposits
March 21, 2017

New numerical modelling quantifies the link of Cu endowment of porphyry deposits with the duration of magmatic-hydrothermal activity and the Sr/Y composition of magmas associated with them. The model shows a remarkable fit with natural porphyry data and can potentially be used in early exploration s…
