Network of quantum sensors boosts precision      (via sciencedaily.com)     Original source 

Quantum sensor technology promises even more precise measurements of physical quantities. A team has now compared the signals of up to 91 quantum sensors with each other and thus successfully eliminated the noise caused by interactions with the environment. Correlation spectroscopy can be used to increase the precision of sensor networks.

Researchers use GPS-tracked icebergs in novel study to improve climate models      (via sciencedaily.com)     Original source 

Research unearthed new information to help scientists better understand circulation patterns of ocean water around glaciers. In the summers of 2014 and 2019, a group of pioneers in glacial research attached GPS devices to 13 icebergs and tracked hourly changes in their positions as they passed through Greenland's Ilulissat Icefjord toward the ocean. Study results showed circulation in the primary fjord is greatly affected by freshwater flow from connecting tributary fjords, which is critically important to consider in circulation models.

Umbrella for atoms: The first protective layer for 2D quantum materials      (via sciencedaily.com)     Original source 

As silicon-based computer chips approach their physical limitations in the quest for faster and smaller designs, the search for alternative materials that remain functional at atomic scales is one of science's biggest challenges. In a groundbreaking development, researchers have engineered a protective film that shields quantum semiconductor layers just one atom thick from environmental influences without compromising their revolutionary quantum properties. This puts the application of these delicate atomic layers in ultrathin electronic components within realistic reach.

Mercury rising: Study sheds new light on ancient volcanoes' environmental impact      (via sciencedaily.com)     Original source 

Massive volcanic events in Earth's history that released large amounts of carbon into the atmosphere frequently correlate with periods of severe environmental change and mass extinctions. A new method to estimate how much and how rapidly carbon was released by the volcanoes could improve our understanding of the climate response, according to an international team.

When the music changes, so does the dance: Controlling cooperative electronic states in Kagome metals      (via sciencedaily.com)     Original source 

Playing a different sound track is, physically speaking, only a minute change of the vibration spectrum, yet its impact on a dance floor is dramatic. People long for this tiny trigger, and as a salsa changes to a tango completely different collective patterns emerge. For such a tiny stimulus to have an effect, the crowd needs to know more than just one dance. Electrons in metals tend to show only one behavior at zero temperature, when all kinetic energy is quenched.

Surprising methane discovery in Yukon glaciers: 'Much more widespread than we thought'      (via sciencedaily.com)     Original source 

Global melting is prying the lid off methane stocks, the extent of which we do not know. A researcher has now discovered high concentrations of the powerful greenhouse gas in meltwater from three Canadian mountain glaciers, where it was not thought to exist -- adding new unknowns to the understanding of methane emissions from Earth's glaciated regions.

Emergency atmospheric geoengineering wouldn't save the oceans      (via sciencedaily.com)     Original source 

Climate change is heating the oceans, altering currents and circulation patterns responsible for regulating climate on a global scale. If temperatures dropped, some of that damage could theoretically be undone. But employing 'emergency' atmospheric geoengineering later this century in the face of continuous high carbon emissions would not be able to reverse changes to ocean currents, a new study finds. This would critically curtail the intervention's potential effectiveness on human-relevant timescales.

80 mph speed record for glacier fracture helps reveal the physics of ice sheet collapse      (via sciencedaily.com)     Original source 

New research documents the fastest-known large-scale breakage along an Antarctic ice shelf. A 6.5-mile crack formed in 2012 over 5-and-a-half minutes, showing that ice shelves can effectively shatter -- though the speed is limited by seawater rushing in. The results help inform large-scale ice sheet models and projections of future sea level rise.
