Canadian tundra formerly covered in rich forest: Ancient plant fossil record shows
SASKATOON–The heady aroma of magnolia blossoms and lotus flowers might have wafted to your nostrils if you had gone for a walk 56 million years ago in the lush green forest which covered Canada’s northernmost islands. Now covered in ice…
Fukushima: Lessons learned from an extraordinary case of soil decontamination
Following the accident at the Fukushima nuclear power plant in March 2011, the Japanese authorities decided to carry out major decontamination works in the affected area, which covers more than 9,000 km 2 . On December 12, 2019, with most…
Deforestation, erosion exacerbate mercury spikes near Peruvian gold mining
Modeling mercury release from soil erosion could help mine-heavy, deforested regions create helpful policies
Beyond ‘shovelomics’: Growing cassava in the air helps study the plant’s mysterious roots
Scientists tossed aside the shovel and studied cassava roots as they grew in real-time, suspended in the air. The innovative use of aeroponics may usher in a new era of science for cassava genetic improvement and sustainable intensification

High-latitude warming initiated the onset of the last deglaciation in the tropics
Stardust from red giants
Around 4.5 billion years ago, an interstellar molecular cloud collapsed. At its centre, the Sun was formed; around that, a disc of gas and dust appeared, out of which the earth and the other planets would form. This thoroughly mixed…

Corals survive to tell the tale of Earth’s newest island eruption
Scientists say coral reefs on a tiny island in the South Pacific have shown incredible resilience and recovery from a recent but very severe disturbance: a volcanic eruption that created a new island. Hunga Tonga – Hunga Ha’apai was (until…
Gilleaudeau to examine lower Mississippian black shales
Geoffrey J. Gilleaudeau, Assistant Professor, Atmospheric, Oceanic and Earth Sciences, is set to begin a project next year that will provide valuable new insight on the uranium isotope system, which has emerged as a premier tool for deciphering Earth’s oxygenation…
Researchers: Put a brake on bioenergy by 2050 to avoid negative climate impacts
Los Altos, California (5 DECEMBER 2019)–The burgeoning bioenergy sector must peak and decline in the next 30 years to alleviate extreme pressure on land, warns researchers in a new analysis published today in Global Change Biology . They assert that…
Animals that evolved in low-disturbance areas more ‘sensitive’ to modern disruption
Animal species that have evolved, and survived, in low-disturbance environments – with little interruption from glaciation, fires, hurricanes, or anthropogenic clearing – are more sensitive to modern forest fragmentation, report Matthew Betts and colleagues. Using information from more than 70…

Drone images show Greenland ice sheet becoming more unstable as it fractures
The world’s second-largest ice sheet, and the single largest contributor to global sea-level rise, is potentially becoming unstable because of fractures developing in response to faster ice flow and more meltwater forming on its surface. Using custom-built drones strong enough…
