Tidewater glaciers, the massive rivers of ice that end in the ocean, may be melting underwater much faster than previously thought, according to a Rutgers co-authored study that used robotic kayaks. The findings, which challenge current frameworks for analyzing ocean-glacier interactions, have implications for the rest of the world's tidewater glaciers, whose rapid retreat is contributing to sea-level rise.
The materials the United States and other countries plan to use to store high level nuclear waste will likely degrade faster than anyone previously knew, because of the way those materials interact, new research shows. The findings, published today in the journal Nature Materials, show that corrosion of nuclear waste storage materials accelerates because of changes in the chemistry of the nuclear waste solution, and because of the way the materials interact with one another.
Tiny meteorites that fell to Earth 2.7 billion years ago suggest that the atmosphere at that time was high in carbon dioxide, which agrees with current understanding of how our planet's atmospheric gases changed over time.
Scientists gain a deeper understanding of turbulent and transitional pipe flows.
The Borexino collaboration has presented new results for the measurement of neutrinos originating from the interior of the Earth. With this update, the researchers have now been able to access 53 events -- almost twice as many as in the previous analysis of the data from the Borexino detector, which is located 1,400 meters below the Earth's surface. The results provide an exclusive insight into processes in the earth's interior that remain puzzling to this day.
In 2017, a massive new region of magnetic field erupted on the sun's surface next to an existing sunspot. The powerful collision of magnetic energy produced a series of solar flares, causing turbulent space weather conditions at Earth. Scientists have now pinpointed for the first time exactly when and where the explosion released the energy that heated spewing plasma to energies equivalent to 1 billion degrees in temperature.
Engineers at Duke University have devised a model that can predict the early mechanical behaviors and origins of an earthquake in multiple types of rock. The model provides new insights into unobservable phenomena that take place miles beneath the Earth's surface under incredible pressures and temperatures, and could help researchers better predict earthquakes -- or even, at least theoretically, attempt to stop them.
Researchers who analyzed well-preserved ocean drilling and global temperature records have added support to the idea that the primary cause of the Cretaceous-Paleogene (K/Pg) mass extinction was an asteroid impact, rather than extreme volcanism.
Japanese researchers used a Global Navigation Satellite System-Acoustic ranging combination technique to detect signals due to slow slip events in the Nankai Trough with seafloor deformations of 5 cm or more and durations on the order of one year. These events generally occurred on the shallow sides of regions with strong interplate coupling and represent variations in interplate friction conditions, which may help simulate the occurrence of megathrust earthquakes originating from this subduction zone and contribute earthquake disaster prevention.
There is a huge seasonal variability in methane seeps in the Arctic Ocean, according to a new paper in Nature Geoscience. "During cold periods the emissions from these seeps are almost halved, as if they are hibernating", says first author Benedicte Ferré.
