Atacama Desert's extreme aridity initiated 20 million years earlier than previously thought, study finds
A collaborative study with the University of Cologne, recently published in Nature Communications, provides compelling evidence that the extreme aridity in the hyperarid core of the Atacama Desert began over 40 million years ago—significantly earlier than previously assumed. The findings require a reconsideration of how deserts form and offer a new perspective on the long-term evolution of Earth's most extreme environments. Researchers from SUERC Centre for the Isotope Sciences are...
Study reveals north–south differences in water isotopes across North America during the last deglaciation
Study reveals north–south differences in water isotopes across North America during the last deglaciation Stephanie Baum Scientific Editor Robert Egan Associate Editor The last deglaciation (between 11,000 and 20,000 years ago) was a period of dramatic natural warming on Earth. During this time, North America experienced the most extensive ice-sheet melting on the planet, which profoundly reshaped its climate and water cycle. But when scientists look at oxygen isotopes in stalagmites—a key...
Nuclear Charge Radii of Sr Isotopes: Reevaluation based on Transition Frequency Measurements in the $5s-5p-4d$ manifold in Sr$^+$
arXiv:2605.04281v2 Announce Type: replace Abstract: High-precision quasi-simultaneous collinear/anticollinear laser spectroscopy was performed to measure the $5s$ $^2S_{1/2}\rightarrow 5p$ $^2P_{1/2}$ (D1), the $5s$ $^2S_{1/2}\rightarrow 5p$ $^2P_{3/2}$ (D2), and the three $4d\rightarrow 5p$ transitions in naturally abundant Sr$^+$ isotopes. For absolute transition frequencies, an accuracy of up to 600 kHz was achieved, while common-mode rejection allowed us to extract isotope shifts with...
SILAC-Site: A streamlined workflow for determining phosphopeptide stoichiometries
Mass spectrometry-based proteomics enables in-depth investigation of protein phosphorylation, quantifying tens of thousands of phosphosites per sample following phosphopeptide enrichment. However, critical information on phosphosite occupancy (stoichiometry) is typically lost during the phospho-enrichment process. Here, we introduce SILAC-Site, a SILAC-based fractionation-free and chemical labelling-free workflow for direct phosphosite stoichiometry evaluation using stable isotope labeling...
Deep Proteoform Sequencing with Top-Down Direct Mass Technology
Individual Ion Mass Spectrometry (I2MS) using Direct Mass Technology mode on an Orbitrap mass spectrometer (DMTm) increases sensitivity, resolution, and mass range for protein analysis. Here, we present an end-to-end workflow for deep proteoform sequencing using top-down mass spectrometry with DMTm. By assigning the charge of individual fragment ions and converting spectra from the m/z to the mass domain, DMTm resolves overlapping isotopic distributions that have limited conventional...
Dino-killing asteroid may have fueled underground life for 8 million years
Dino-killing asteroid may have fueled underground life for 8 million years Gaby Clark Scientific Editor Robert Egan Associate Editor The asteroid that caused the extinction of the dinosaurs also created an underground environment suited to supporting new life, and new research suggests it lasted for millions of years longer than previously suspected. The finding has surprised the international team of researchers behind it, who came to their conclusions by pairing sophisticated new analysis...
Magnesium transporter discovery could improve rice nutrition and taste
Magnesium transporter discovery could improve rice nutrition and taste Sadie Harley Scientific Editor Robert Egan Associate Editor Rice is a staple food for nearly half the global population and an important dietary source of magnesium, a mineral essential for human health, plant growth and energy metabolism. Although magnesium is known to influence grain quality and taste, the biological mechanism controlling how the mineral reaches rice grains has remained largely unknown. Understanding...
Thirty years at El Mirón cave uncover 40,000 years of Iberian prehistory
Thirty years at El Mirón cave uncover 40,000 years of Iberian prehistory Lisa Lock Scientific Editor Robert Egan Associate Editor For the past three decades, a team of archaeologists have been uncovering some of the field's most recent monumental discoveries, relying on gut instinct, persistent hard work, and cutting-edge methods and technologies. The El Mirón Cave excavation project has been a long-term commitment for the lead researchers, fueled by each new discovery and a continued...
From approval to access: Europe’s next health imperative
Europe’s health ambition is returning to the political agenda. With a focus on clinical trials, biotechnology and cardiovascular health, the Health Package signals Brussels’ intent to prioritize innovation, research and prevention as pillars of Europe’s competitiveness and resilience. But for many patients, one reality remains unchanged: access to innovative medicines remains too slow. Today, European patients are waiting longer than ever to...
Development of a 3D-CNN-based Prediction Model for Migration Barriers in Plasma-Wall Interactions
arXiv:2604.05521v2 Announce Type: replace Abstract: Understanding the long-term transport of hydrogen isotopes in plasma-facing materials, such as tungsten, is critical for the steady-state operation of magnetic confinement fusion reactors. However, dynamically updating the transition parameters for kinetic Monte Carlo (kMC) simulations as the atomic structure evolves under continuous plasma irradiation remains a severe computational bottleneck. Conventionally, calculating these migration...
