In a study published in Nature Geoscience, the team explored the physics of “stagnant slabs.” These geophysical oddities form when huge chunks of Earth’s oceanic plates are forced deep underground at the edges of certain continental plates. The chunks sink down into the planet’s interior for hundreds of miles until they suddenly — and for reasons ...
Archaeologists from the University of Western Australia working with Traditional Custodians from the Birriliburru Indigenous Protected Area (IPA) have recovered evidence that aboriginals lived in the Australian arid zone 50,000 years ago. This is 10,000 years earlier than previously understood for the interior deserts of Australia, and among some of the earliest known evidence of ...
A new analysis of thousands of very small earthquakes that have occurred in the San Bernardino basin near the San Andreas and San Jacinto faults suggests that the unusual deformation of some — they move in a different way than expected — may be due to “deep creep” 10 km below the Earth’s surface, say ...
The interaction between a chemical slurry and ancient shale during hydraulic fracking is producing radioactive waste, according to Dartmouth College research. The study, detailed in twin papers appearing in Chemical Geology, is the first research that characterizes the phenomenon of radium transfer in the widely-used method to extract oil and gas. The findings add to ...
The most severe mass extinction in Earth’s history occurred with almost no early warning signs, according to a new study by scientists at MIT, China, and elsewhere. The end-Permian mass extinction, which took place 251.9 million years ago, killed off more than 96 percent of the planet’s marine species and 70 percent of its terrestrial ...
Committed to addressing the country’s severe air pollution, China is attempting a shift from coal to natural gas and is considering a variety of sources, including domestic and imported gas options, as well as creating its own synthetic gas from coal. A team of researchers led by Princeton University investigated the environmental impacts of transitioning ...
A new ultrasound wearable patch to monitor blood pressure in arteries deep beneath the skin could help people detect cardiovascular problems earlier on and with greater precision. In tests, the patch performed as well as some clinical methods to measure blood pressure. Applications include real-time, continuous monitoring of blood pressure changes in patients with heart ...
The reason Pluto lost its planet status is not valid, according to new research from the University of Central Florida. In 2006, the International Astronomical Union, a global group of astronomy experts, established a definition of a planet that required it to “clear” its orbit, or in other words, be the largest gravitational force in ...
Europe’s decision to promote the use of wood as a “renewable fuel” will likely greatly increase Europe’s greenhouse gas emissions and cause severe harm to the world’s forests, according to a new comment paper published in Nature Communications. European officials agreed on final language for a renewable energy directive earlier this summer that will almost double Europe’s use ...
Millennia ago, ancient farmers cleared land to plant wheat and maize, potatoes and squash. They flooded fields to grow rice. They began to raise livestock. And unknowingly, they may have been fundamentally altering the climate of the Earth. A study published in the journal Scientific Reports provides new evidence that ancient farming practices led to a rise ...
