The Earth has known several mass extinctions over the course of its history. One of the most important happened at the Permian-Triassic boundary 250 million years ago. Over 95% of marine species disappeared and, up until now, scientists have linked this extinction to a significant rise in Earth temperatures. But researchers from the University of Geneva (UNIGE), Switzerland, working alongside the University of Zurich, discovered that this extinction took place during a short ice age which preceded the global climate warming. It’s the first time that the various stages of a mass extinction have been accurately understood and that scientists have been able to assess the major role played by volcanic explosions in these climate processes. This research, which can be read in Scientific Reports, completely calls into question the scientific theories regarding these phenomena, founded on the increase of CO2 in the atmosphere, and paves the way for a new vision of the Earth’s climate history.

At high latitudes, such as near Antarctica and the Arctic Circle, the ocean’s surface waters are cooled by frigid temperatures and become so dense that they sink a few thousand meters into the ocean’s abyss.

Ocean waters are thought to flow along a sort of conveyor belt that transports them between the surface and the deep in a never-ending loop. However, it remains unclear where the deep waters rise to the surface, as they ultimately must. This information would help researchers estimate how long the ocean may store carbon in its deepest regions before returning it to the surface.

VTT Technical Research Centre of Finland is coordinating the BALANCE project, which brings together leading European research institutes in the field of electrochemical conversion. The project aims to demonstrate a technology that enables flexible storage of large amount of renewable power. Such technologies are needed for the further integration of additional wind and solar power. The European Commission funds the project by 2.5 million euros.

Over the past 30 years, Dr. Marsha Campbell-Yeo has seen incredible advancements in neonatal care — developments in technology and practice that have improved outcomes for vulnerable newborns across North America and around the world.

“However, the focus of these innovations and transformations in care has been almost exclusively directed toward health care providers and technological advancements,” said Dr. Campbell Yeo, associate professor in the School of Nursing at Dal and a clinician scientist at the IWK Health Centre. “Until recently, parents have not only been underutilized in the setting of neonatal intensive care, but often excluded all together.”

Environmental scientists and policymakers value long-term research to an extent that far outstrips the amount of funding awarded for it, according to a study published today.

Graduate students and faculty members in the Oregon State University College of Science were part of a collaboration that evaluated the perceived benefits of long-term ecological and environmental studies – known as LTEES – to both researchers and those who determine environmental policy. 

The temperature of Earth’s interior affects everything from the movement of tectonic plates to the formation of the planet.

A new study led by Woods Hole Oceanographic Institution (WHOI) suggests the mantle—the mostly solid, rocky part of Earth’s interior that lies between its super-heated core and its outer crustal layer – may be hotter than previously believed. The new finding, published March 3 in the journal Science, could change how scientists think about many issues in Earth science including how ocean basins form.

Leicester research reveals the impact of black carbon on bacteria in the respiratory tract

Images of our faces exist in numerous important databases – driver’s license, passport, law enforcement, employment – all to accurately identify us. But can these images continue to identify us as we age?

Cities play a key role in reducing greenhouse gas emissions to combat climate change, but directly measuring emissions remains a challenge.

Philadelphia communities along the Schuylkill River and Darby Creek now have new tools to help inform residents of impending flooding. The U.S. Geological Survey recently installed three new streamgages in Manayunk, Eastwick, and downtown near 30th St., which will monitor water levels, and provide vital data used by emergency managers and flood forecasters to help protect lives and property.
