Dark energy survey scientists release analysis of all six years of survey data‎

The Dark Energy Survey Collaboration collected information on hundreds of millions of galaxies across the universe using the U.S. Department of Energy-fabricated Dark Energy Camera, mounted on the U.S. National Science Foundation Víctor M. Blanco 4-meter Telescope at CTIO, a program of NSF NOIRLab. Their completed analysis combines all six years of data for the first time and yields constraints on the universe's expansion history that are twice as tight as past analyses.

Increased soil salinity alters global inorganic carbon storage, finds study‎

A new global study shows that increasing soil salinity is systematically reshaping the storage and distribution of soil inorganic carbon (SIC), a key but often-overlooked part of terrestrial ecosystems. The findings, published in the Proceedings of the National Academy of Sciences on January 20, provide the first comprehensive global assessment of how soil salinization influences inorganic carbon storage and highlight its implications for the global carbon cycle.

Beneath Antarctica's largest ice shelf, a hidden ocean is revealing its secrets‎

Beneath Antarctica's Ross Ice Shelf lies one of the least measured oceans on Earth—a vast, dark cavity roughly twice the volume of the North Sea.

New research reveals how dread shapes decision-making‎

A new study reveals that people are far more emotionally affected by anticipating negative future outcomes than by imagining positive ones, helping to explain why many individuals avoid uncertainty and prefer decisions to be resolved sooner rather than later.

Tuning color through molecular stacking: A new strategy for smarter pressure sensors‎

Piezofluorochromism, the phenomenon of materials reversibly changing their fluorescent color when pressure is applied, is used to create the pressure sensors used in automotive and medical industries. By monitoring color changes, researchers can visually recognize phenomena, such as chemical changes, that actually take place. However, as devices get increasingly complicated, there is an increasing demand for ways to produce more sensitive sensors.

Aging zoo animals threaten long-term species conservation goals‎

Many mammal populations in European and North American zoos are aging—a trend that jeopardizes the long-term viability of so-called reserve populations and, with it, a core mission of modern zoos in global species conservation. This is the central finding of a new international study published in the journal Proceedings of the National Academy of Sciences.

2D topological crystalline insulator turns decade-old prediction into reality‎

Physicists from University of Jyväskylä and Aalto University (Finland) have experimentally realized a two-dimensional topological crystalline insulator. This is a quantum material that has been theoretically predicted for more than a decade but had remained inaccessible due to materials challenges.
