Climate change can goad volcanoes into life
September 26, 2017

The possibility that temporary closure of the Gibraltar gateway and isolation of the Mediterranean from the Atlantic during the Messinian Salinity Crisis (5.96 My ago) led to near complete desiccation of the Mediterranean has been debated for more than four decades, but no definitive proof of this h…

A new study by Greber et al. shows that the most abundant rock in Earth’s continental crust 3.5 billion years ago was similar to the granitic peaks from Yosemite National Park (USA). Photo: Basil Greber

A pervasive tropical climate in SE Tibet 35.5 Ma ago
September 18, 2017

A global cooling of the Earth climate has characterized the Eocene-Oligocene transition that initiated the Antarctic glaciation ca. 33.7 Ma and a shift from greenhouse to icehouse conditions. What was the impact of these climatic changes in the continental realm, particularly in tropical regions aff…

Cellular toxicity pathways of mercury
August 22, 2017

Contamination by mercury is a worldwide concern because of Hg toxicity and biomagnification in aquatic food webs. Nevertheless, the bioavailability and cellular toxicity pathways of the two mercury species -inorganic and methylmercury- prevailing in the aquatic media remain poorly understood. By us…

New Paper in Geology
July 24, 2017

Continuous outgassing at open conduit basaltic volcanoes significantly decrease their explosive potential. What is controlling the longevity and efficiency of gas liberation, which is a common process at several systems such as Etna, Stromboli, and Piton de la Fournaise? This paper discusses the res…

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…
