Extreme warming intensified lacustrine deoxygenation and methane cycling during the Paleocene-Eocene Thermal Maximum

open access: yesCommunications Earth & Environment
Lakes are critical sentinels of climate change, yet their responses to rapid warming remain poorly understood. Here we present organic geochemical data of lacustrine sediments from eastern China during the Paleocene-Eocene Thermal Maximum (56 million ...

Past, present and future of local crop evolution

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Promoting agrobiodiversity is a promising strategy for mitigating the negative effects of climate change on global food security. We highlight the central role evolutionary processes play in harnessing the potential of local crops by integrating genomics, archaeology, ethnobotany and traditional ecological knowledge (TEK).

Biomolecular Interaction Prediction in the Pre‐ and Post‐AlphaFold Era: The 8th CAPRI Evaluation

open access: yesProteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT We report on the 8th CAPRI Evaluation period, capturing the assessment of CAPRI Rounds 47 to 55 (excluding the CASP and COVID‐related Rounds), which have witnessed the transition to AI‐driven prediction tools such as AlphaFold and related alternatives. The prediction Rounds in this evaluation are characterized by a high level of difficulty due

Experimental characterization and grain-based numerical modeling of multiscale fracture mechanisms in pre-fractured granite

open access: yesScientific Reports
The mechanical behavior of pre-fractured granite is primarily governed by pre-existing fractures, in which macro-crack evolution emerges from micro-crack accumulation.

Multimodal targets of (‐)‐α‐thujone mediating avoidance behavior of a stored‐products pest, Tribolium castaneum, in response to irritant stimuli

open access: yesPest Management Science, EarlyView.
We identified four kinds of target molecules against (‐)‐α‐thujone associating avoidance behavior in Tribolium castaneum, indicating multimodality. Abstract BACKGROUND The reciprocal evolutionary processes among phytophagous insects and host plants involve host shift in the herbivorous insects in response to defense chemicals, such as plant‐derived ...

EnKF and expectation‐maximization based parameter estimation of a convective gravity‐wave parameterization using Strateole 2 constant‐level balloon data

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
An offline methodology is applied to estimate parameters of a convective gravity‐wave scheme using momentum flux (MF) observations from constant‐level balloons (left panels: pdfs of east and west MFs in green from observations and black from EnKF). The approach integrates an ensemble Kalman filter with an expectation‐maximization algorithm and permits ...

Dehydration-induced supralithostatic fluid overpressure in metapelites from Northern Korea

open access: yesCommunications Earth & Environment
Orogenic reconstructions typically assume lithostatic pressure, which can be converted into burial depth. Deviations from lithostatic conditions, such as fluid overpressure, are recognized but poorly understood in natural rocks.

Tracing Three Decades of Low Earth Orbit Satellite Communication Development: A Bibliometric and Main Path Analysis of Network Architectures, Protocol Evolution, and Emerging Intelligent Services

open access: yesInternational Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT Low Earth Orbit (LEO) satellite communication systems have evolved into a critical component of global broadband networks, enabling wide‐area connectivity, IoT services, and intelligent multilayer satellite–terrestrial integration. Despite rapid advancements in constellation deployment, routing mechanisms, resource management, and LEO–5G/6G ...

Was the Kalkarindji Continental Flood Basalt Province a Driver of Environmental Change at the Dawn of the Phanerozoic?

open access: yesGeophysical Monograph Series, Page 435-447., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Heavy iron isotopes in arc rocks reveal anoxic sediment recycling in subduction zones

open access: yesCommunications Earth & Environment
The formation mechanism of arc mafic rocks with heavy iron isotope signature remains enigmatic. Here we report Fe-Mo-Sr-Nd-Hf isotope data of arc rocks from Northeast China. The studied arc rocks have δ56Fe values (0.08‰ to 0.23‰) comparable to or higher
