First amber discovered in Antarctica brings new insights into Cretaceous forests
Close-up of approximately 70 µm amber extracted from lignite in the MeBo core deposit. Credit: Alfred-Wegener-Institut / V. Schumacher Until recently, there was a gap in the world map where amber was discovered: Antarctica. But thanks to a team led by Dr. Johann P. Klages of the Alfred Wegener Institute, Helmholtz Center for Polar and Marine Research, and Dr. Henny…

High-resolution IR spectroscopy reveals new insights into hydrogen bonding in hydrogen sulfide
Far-infrared spectrum of H2S-H2S at T = 0.37 K calculated using ab initio intermolecular potentials and dipole functions. Credit: Nature Communications (2024). DOI: 10.1038/s41467-024-53444-6 At first glance, water and the foul-smelling molecule hydrogen sulfide don’t seem to have much in common. However, if you invest a little energy, some differences will disappear. At first glance, the smell of soft drink…

Geologists rewrite textbooks with new insights from Grand Canyon’s Cambrian rocks
GSA Today’s cover features the Cambrian period of the Grand Canyon. Credit: GSA Since shortly after our planet formed, Earth’s 4.6 billion year history has been dominated by single-celled life. About 500 million years ago, a dramatic event called the Cambrian “explosion” occurred, during which an incredible diversity of life forms was left behind in the rock record. These fossils…

Measurements from ‘lost’ sea glider provide new insights into Antarctic ice melting
Gillian Damerel (former UEA) prepares to deploy the Sea Glider Merlin with the Ross Ice Shelf in the background. Credit: Walker Smith A new study reveals for the first time how rising sea temperatures have accelerated the melting of Antarctica’s major ice shelves over the past 40 years. Scientists at the University of East Anglia (UEA) say the study, which…

Unlocking efficiency in next-generation chips: Researchers confirm thermal insights in small circuits
Microstructure of as-deposited and annealed copper films. (a–c) STEM images of as-deposited ~27 nm PVD, ~44 nm PVD-EP, and ~118 PVD films, respectively. The morphology of these films after annealing at 500 °C is shown in (d–f). The micrographs show representative areas of the as-deposited and annealed films. The grain size distributions of both the as-deposited and annealed films are…

New insights into bubble interference could enhance electrode design
(A) Diagram of the high-level ML architecture used for bubble identification. Note that the Mask R-CNN architecture has an additional convolutional layer to generate the mask, whereas Faster R-CNN does not. (B) Image of a b200 grid nucleation surface with oxygen bubble nucleation annotated with predictions and union (IoU) scores. Green indicates the highest IoU (≥0.9) and red indicates the…
