Scientists shine light on 66-million-year-old meteorite wildfire mystery

Scientists have discovered that the meteorite that wiped out Earth's dinosaurs instantly ignited forest wildfires thousands of kilometers away from its impact zone. At the...

Study unearths ancient reef structures high and dry on the Nullarbor Plain

Using advanced satellite imagery, Curtin University researchers and international collaborators discovered an ancient reef-like landform "hidden" in plain sight on the Nullarbor Plain that...

Residential exposure to petroleum refining could be related to strokes in the southern US

A new study has found a strong link between exposure to pollutants from petroleum refineries and stroke rates in the southern United States. The...

Pollutants from burning structures linger in waterways post-wildfire

According to researchers in a review paper that highlights the need for more research in the area, as the frequency of wildfires has increased,...

Researchers discover expanding and intensifying low-oxygen zone in the Arabian gulf

Over three decades, a team of researchers from NYU Abu Dhabi's Arabian Center for Climate and Environmental Sciences (ACCESS) studied the evolution of dissolved...

Seismic device made for extra-terrestrial research can help tackle climate change on Earth

Although underground carbon sequestration is a promising approach to combating climate change, significant obstacles must be overcome before this technology can be used on...

Global energy spectrum of the general oceanic circulation

For the first time, researchers at the University of Rochester have quantified the energy of ocean currents larger than 1,000 kilometres in length. During...

Phase transitions in olivine may be the cause of deep seismic faulting

Deep-focus earthquakes are earthquakes that occur at depths of several hundred kilometers in the mantle. Such earthquakes can cause serious disasters, such as the...

Grimy windows could be harboring toxic pollutants

Dirty windows can harbour potentially harmful pollutants under protective films of fatty acids from cooking emissions, which can linger for a long time. According to...

Conversion to LED lighting brings a new kind of light pollution to Europe

A team of Exeter University researchers discovered that the slow conversion of outdoor lighting to LEDs across much of Europe has resulted in the...

Tropical wetlands emit more methane than previously thought

Since 2007, the world's atmospheric methane concentration has increased rapidly, but scientists aren't sure why. This is a problem because methane is an extremely...

UN sums up climate science: world heading in the wrong direction

With weather disasters costing $200 million per day and irreversible climate catastrophe looming, the world is "heading in the wrong direction," according to the...

Little Ice Age study reveals North Atlantic reached tipping point

Scientists used centuries-old clam shells to reconstruct how the North Atlantic climate system reached a "tipping point" prior to the Little Ice Age. The Little...

Mineral-microbe interactions play important roles in geological and environmental processes

A team of scientists critically summarises major advances in mineral-microbe interactions, including molecular mechanisms of interactions and macroscopic manifestations of such interactions over time,...

Natural climate solutions help mitigate climate change in China

Natural climate solutions (NCS), which include various land stewardship options, are methods of capturing carbon in terrestrial pools and/or lowering greenhouse gas (GHG) emissions....
