Published Robot provides unprecedented views below Antarctic ice shelf


With the help of an underwater robot, known as Icefin, a U.S.- New Zealand research team has obtained an unprecedented look inside a crevasse at Kamb Ice Stream -- revealing more than a century of geological processes beneath the Antarctic ice.
Published Quantum chemistry: Molecules caught tunneling


Quantum effects can play an important role in chemical reactions. Physicists have now observed a quantum mechanical tunneling reaction in experiments. The observation can also be described exactly in theory. The scientists provide an important reference for this fundamental effect in chemistry. It is the slowest reaction with charged particles ever observed.
Published New study could help pinpoint hidden helium gas fields -- and avert a global supply crisis


Helium -- essential for many medical and industrial processes -- is in critically short supply worldwide. Production is also associated with significant carbon emissions, contributing to climate change. This study provides a new concept in gas field formation to explain why, in rare places, helium accumulates naturally in high concentrations just beneath the Earth's surface. The findings could help locate new reservoirs of carbon-free helium -- and potentially also hydrogen.
Published Climate trends in the west, today and 11,000 years ago


What we think of as the classic West Coast climate began just about 4,000 years ago, finds a study on climate trends of the Holocene era.
Published Mysteries of the Earth: Researchers predict how fast ancient magma ocean solidified


Previous research estimated that it took hundreds of million years for the ancient Earth's magma ocean to solidify, but new research narrows these large uncertainties down to less than just a couple of million years.
Published Ancient proteins offer new clues about origin of life on Earth



By simulating early Earth conditions in the lab, researchers have found that without specific amino acids, ancient proteins would not have known how to evolve into everything alive on the planet today -- including plants, animals, and humans.
Published New material may offer key to solving quantum computing issue


A new form of heterostructure of layered two-dimensional (2D) materials may enable quantum computing to overcome key barriers to its widespread application, according to an international team of researchers.
Published Heterostructures support predictions of counterpropagating charged edge modes at the v=2/3 fractional quantum Hall state



Researchers have tested models of edge conduction with a device built on top of the semiconductor heterostructure which consists of gold gates that come close together. Voltage is applied on the gates to direct the edge states through the middle of the point contact, where they are close enough that quantum tunneling can occur between the edge states on opposite sides the sample. Changes in the electrical current flowing through the device are used to test the theorists' predictions.
Published Let there be (controlled) light


In the very near future, quantum computers are expected to revolutionize the way we compute, with new approaches to database searches, AI systems, simulations and more. But to achieve such novel quantum technology applications, photonic integrated circuits which can effectively control photonic quantum states -- the so-called qubits -- are needed. Physicists have made a breakthrough in this effort: for the first time, they demonstrated the controlled creation of single-photon emitters in silicon at the nanoscale.
Published Theory can sort order from chaos in complex quantum systems


Theoretical chemists have developed a theory that can predict the threshold at which quantum dynamics switches from 'orderly' to 'random,' as shown through research using large-scale computations on photosynthesis models.
Published The quantum twisting microscope: A new lens on quantum materials


One of the striking aspects of the quantum world is that a particle, say, an electron, is also a wave, meaning that it exists in many places at the same time. Researchers make use of this property to develop a new type of tool -- the quantum twisting microscope (QTM) -- that can create novel quantum materials while simultaneously gazing into the most fundamental quantum nature of their electrons.
Published Early Cretaceous shift in the global carbon cycle affected both land and sea


Geologists doing fieldwork in southeastern Utah's Cedar Mountain Formation found carbon isotope evidence that the site, though on land, experienced the same early Cretaceous carbon-cycle change recorded in marine sedimentary rocks in Europe. This ancient carbon-cycle phenomenon, known as the 'Weissert Event' was driven by large, sustained volcanic eruptions in the Southern Hemisphere that greatly increased carbon dioxide levels in the atmosphere and produced significant greenhouse climate effects over a prolonged time.
Published Deep earthquakes could reveal secrets of the Earth's mantle


A new study suggests there may be a layer of surprisingly fluid rock ringing the Earth, at the very bottom of the upper mantle.
Published Meteorite crater discovered in French winery


Countless meteorites have struck Earth in the past and shaped the history of our planet. It is assumed, for example, that meteorites brought with them a large part of its water. The extinction of the dinosaurs might also have been triggered by the impact of a very large meteorite. It turns out that the marketing 'gag' of the 'Domaine du Météore' winery is acutally a real impact crater. Meteorite craters which are still visible today are rare because most traces of the celestial bodies have long since disappeared again.
Published Bouncing seismic waves reveal distinct layer in Earth's inner core


Data captured from seismic waves caused by earthquakes has shed new light on the deepest parts of Earth's inner core, according to seismologists.
Published New quantum sensing technique reveals magnetic connections


A research team demonstrates a new way to use quantum sensors to tease out relationships between microscopic magnetic fields.
Published Climate: Lessons from the latest global warming


56 million years ago, the Earth experienced one of the largest and most rapid climate warming events in its history: the Paleocene-Eocene Thermal Maximum (PETM), which has similarities to current and future warming. This episode saw global temperatures rise by 5-8°C. It was marked by an increase in the seasonality of rainfalls, which led to the movement of large quantities of clay into the ocean, making it uninhabitable for certain living species. This scenario could be repeated today.
Published What do early Earth's core formation and drip coffee have in common?


A new technique provides fresh insight into the process by which the materials that formed Earth's core descended into the depths of our planet, leaving behind geochemical traces that have long mystified scientists.
Published Earthquake scientists have a new tool in the race to find the next big one


New research on friction between faults could aid in predicting the world's most powerful earthquakes. Researchers discovered that fault surfaces bond together, or heal, after an earthquake. A fault that is slow to heal is more likely to move harmlessly, while one that heals quickly is more likely to stick until it breaks in a large, damaging earthquake. Tests allowed them to calculate a slow, harmless type of tremor. The discovery alone won't allow scientists to predict when the next big one will strike but it does give researchers a valuable new way to investigate the causes and potential for a large, damaging earthquake to happen, and guide efforts to monitor large faults like Cascadia in the Pacific Northwest.
Published Engineers discover a new way to control atomic nuclei as 'qubits'


Researchers propose a new approach to making qubits, the basic units in quantum computing, and controlling them to read and write data. The method is based on measuring and controlling the spins of atomic nuclei, using beams of light from two lasers of slightly different colors.
