Detecting C4 plants consumption is central to investigating animal ecology, agriculture, dietary transitions, and socio-environmental adaptations, and can be done using carbon isotope analysis. The conventional δ¹³C threshold used to ide...
Phreatic eruptions at Whakaari Volcano driven by hydrothermal mineralisation and magmatic gas input [0.03%]

Phreatic eruptions are a potentially lethal type of volcanic activity that is notoriously difficult to forecast. Understanding the complex processes that make eruptions more likely is a key step towards detecting precursory signals. Here, w...
Hydroclimatic instability accelerated the socio-political decline of the Tang Dynasty in northern China [0.03%]
华北地区气候变化的不确定性加速了唐朝的社会政治衰落

M Kempf et al.
Extreme flooding and prolonged, intensifying droughts have played a critical role in the rise and collapse of preindustrial states and empires worldwide, triggering cascading impacts such as crop failure, famine, and migration that undermin...
Terrestrial atmospheric ion implantation occurred in the nearside lunar regolith during the history of Earth's dynamo [0.03%]
地球发电机历史上月球近侧风化层发生过 terrestrial 大气离子注入事件
Shubhonkar Paramanick,Eric G Blackman,John A Tarduno et al.
Shubhonkar Paramanick et al.
Light volatile elements in the lunar regolith are thought to be a mixture of the solar wind and Earth's atmosphere, the latter sourced in the absence of geomagnetic field. However, the extent to which both the current and primitive geodynam...
The bound growth of induced earthquakes could de-risk hydraulic fracturing [0.03%]
诱发地震限域增长或可降低水力压裂风险
Ryan Schultz,Federica Lanza,Ben Dyer et al.
Ryan Schultz et al.
The world's energy supply depends critically on hydraulic fracturing (HF) to access otherwise uneconomical resources. Unfortunately, HF also has the potential to induce larger earthquakes - with some projects being prematurely terminated be...

Aluminum-rich clay minerals are detected across the ancient surface of Mars and record intervals of intense alteration by liquid water. On Earth, these clay minerals can form from hydrothermal alteration or rainfall-driven chemical weatheri...
Aragonite lithium/magnesium as an indicator of calcification media saturation state in marine calcifiers [0.03%]
文石中的锂/镁比值可作为海洋钙化生物所在介质饱和度的指示指标
Cristina Castillo Alvarez,Edmund Hathorne,Matthieu Clog et al.
Cristina Castillo Alvarez et al.
Marine calcifiers support ecosystem services, including shell fisheries and coral reefs. Constraining the saturation state of the calcification media of these organisms is essential to understand the response of biomineralisation to environ...
Neogene plant macrofossils from West Antarctica reveal persistence of Nothofagaceae forests into the early Miocene [0.03%]
新生代南极西区发现植物化石揭示南方山龙眼森林在早中新世的持续存在
Joaquin Bastias-Silva,Marcelo Leppe,Leslie Manriquez et al.
Joaquin Bastias-Silva et al.
The extinction of woody vegetation in Antarctica remains difficult to constrain due to its fragmented macrofossil record. Despite its long-standing polar position, Antarctica hosted extensive vegetation throughout the Paleogene. This change...
Planning with emission models reduces the carbon footprint of new reservoirs [0.03%]
采用排放模型进行规划可降低新水库的碳足迹
Tomasz Janus,Christopher Barry,Shelly Win et al.
Tomasz Janus et al.
Reservoirs collectively contribute 1-2% of global anthropogenic greenhouse gas emissions, although individual emissions can vary widely. While emission models have considerably advanced our understanding of the lifetime carbon impacts of re...

Explosive volcanic eruptions are a major geo-hazard. Given the energetic nature of eruptive processes, direct observation is limited, making the study of deposits and pyroclast textures essential for understanding eruption dynamics. Experim...
