Pacific Ocean set to make way for world's next supercontinent
Pacific Ocean set to make way for world’s next supercontinent
New Curtin University-led research has found that the world's next supercontinent, Amasia, will most likely form when the Pacific Ocean closes in 200 to 300 million years. Published in National Science Review , the research team used a supercomputer to simulate how a supercontinent forms and found that because the Earth has been cooling for billions of years, the thickness and strength of the plates under the oceans reduce with time, making it difficult for the next supercontinent to assemble by closing the "young" oceans, such as the Atlantic or Indian oceans.

Marine ice sheets were decisive in the acceleration of global warming
Marine ice sheets were decisive in the acceleration of global warming
The intensity and rate of melt during the penultimate ice melting was much higher than previously thought, according to a study published in the journal Nature Communications . According to conclusions of the study, in this climate change scenario, the instability of marine-based ice sheets —those that flow directly into the ocean— was instrumental in accelerating global warming.

Lunar glass shows Moon asteroid impacts mirrored on Earth
Lunar glass shows Moon asteroid impacts mirrored on Earth
A Curtin-led research team has found asteroid impacts on the Moon millions of years ago coincided precisely with some of the largest meteorite impacts on Earth, such as the one that wiped out the dinosaurs. The study also found that major impact events on Earth were not stand-alone events, but were accompanied by a series of smaller impacts, shedding new light on asteroid dynamics in the inner solar system, including the likelihood of potentially devastating Earth-bound asteroids.

New evidence for liquid water beneath the south polar ice cap of Mars
An international team of researchers has revealed new evidence for the possible existence of liquid water beneath the south polar ice cap of Mars. Scientists from the University of Sheffield are part of an international team of researchers that have revealed new evidence for the possible existence of liquid water beneath the south polar ice cap of Mars The findings provide the first independent line of evidence, using data other than radar, that there is liquid water beneath Mars- south polar ice cap Like Earth, Mars has thick water ice caps at both poles.

Flaring allows more methane into the atmosphere than we thought
Study: Inefficient and unlit natural gas flares both emit large quantities of methane abq0385 Oil and gas producers rely on flaring to limit the venting of natural gas from their facilities, but new research led by the University of Michigan shows that in the real world, this practice is far less effective than estimated-releasing five times more methane in the U.S. than previously thought.

Predicting the next volcanic eruption, plus other stories
Predicting the next volcanic eruption Volcanic eruptions can be tricky to predict. Magma stored below volcanoes contains dissolved gases, including carbon dioxide, which escape to the surface and can be sampled at different times (before, after or during) an eruption to provide clues about the next one.

Seawater could have provided phosphorous required for emerging life
The problem of how phosphorus became a universal ingredient for life on Earth may have been solved by researchers from the University of Cambridge and the University of Cape Town, who have recreated primordial seawater containing the element in the lab.

The distance to the Moon and the length of the day 2.46 billion years ago
At a slow pace, the Moon is moving away from the Earth and the Earth is rotating more slowly around its axis. To say something about these changes in the distant past, geologists use information stored in rocks and fossils. But the further back in time they look, the more difficult it becomes to retrieve this information.

Deepest scientific ocean drilling effort sheds light on Japan’s next ’big one’
Scientists who drilled deeper into an undersea earthquake fault than ever before have found that the tectonic stress in Japan's Nankai subduction zone is less than expected. The results of the study led by the University of Washington and the University of Texas at Austin, published Sept. 5 in Geology, are a puzzle, since the fault produces a great earthquake almost every century and was thought to be building for another big one.

Rising sea temperatures threaten Atlantic populations of Bulwer’s petrels
The impact of the rise in sea temperatures predicted by the Intergovernmental Panel on Climate Change (IPCC) could affect the survival of the North Atlantic populations of Bulwer's petrel in the Azores, Canary Islands and Cape Verde, according to a study conducted by the Seabird Ecology Group of the Faculty of Biology and the Biodiversity Research Institute ( IRBio ) of the University of Barcelona.

Improved air quality accelerates global warming in recent decades
Improved air quality accelerates global warming in recent decades
An international research team led by Leipzig University has used satellite data to demonstrate that concentrations of pollutant particles have decreased significantly since the year 2000. This is necessary due to their impact on health. But it is also of great significance for another reason, since it has reduced the particles- cooling effect on the climate.

Ocean scientists measure sediment plume stirred up by deep-sea-mining vehicle
A new field study reveals a previously unobserved fluid dynamic process that is key to assessing impact of deep-sea mining operations. What will be the impact to the ocean if humans are to mine the deep sea? It's a question that's gaining urgency as interest in marine minerals has grown.

New Software Platform Advances Understanding of the Surface Finish of Manufactured Components
New Software Platform Advances Understanding of the Surface Finish of Manufactured Components
Scientists develop platform that combines measurements of surface topography in a digital twin Scientists from the University of Freiburg, Germany, and the University of Pittsburgh have developed a software platform that facilitates and standardizes the analysis of surfaces. The platform enables users to create a digital twin of a surface and thus to help predict, for example, how quickly it wears out, how well it conducts heat, or how well it adheres to other materials.

Lava from 2021 Icelandic eruption gives rare view of deep churnings beneath volcano
Lava from 2021 Icelandic eruption gives rare view of deep churnings beneath volcano
After centuries without volcanic activity, Iceland's Reykjanes peninsula sprang to life in 2021 when lava erupted from the Fagradalsfjall volcano. New research involving the University of Cambridge helps us see what is going on deep beneath the volcano by reading the chemistry of lavas and volcanic gases almost as they were erupted.

The meandering waves that connect jet streams to global warming
Extra waves may be great for surfers, but they can lead to tumultuous weather when they start showing up in jet streams. That's because jet streams - blowing ribbons of wind that encircle the earth - play a critical role in the location and severity of weather events, such as the recent floods that devastated Kentucky.

A warm intrusion in the Arctic causes extreme pollution levels
During the MOSAiC research expedition, conducted in the Arctic pack ice between 2019 and 2020, scientists observed an atmospheric perturbation triggered by the intrusion of a highly polluted warm air-mass. A first study providing further insight into the phenomenon and its potential implications has just been published.

Study unearths ancient reef structure high and dry on the Nullarbor Plain
Study unearths ancient reef structure high and dry on the Nullarbor Plain
Curtin researchers and international collaborators using advanced satellite imagery have discovered an ancient reef-like landform 'hidden' in plain view on the Nullarbor Plain, which has been preserved for millions of years since it first formed when the Plain was underwater. Research author Dr Milo Barham, from the Timescales of Mineral Systems Group within Curtin's School of Earth and Planetary Sciences ásaid the finding further challenged the understanding that the Nullarbor Plain, which emerged from the ocean about 14 million years ago, was essentially flat and featureless.

Birmingham telescope discovers two new temperate rocky worlds
An international research team has announced the discovery of two "super-Earth" planets orbiting a star 100 light-years from Earth. The team, which includes astronomers at the University of Birmingham detected the planets orbiting LP 890-9, a small, cool star located about 100 light-years from Earth.
