Intense alteration on early Mars revealed by high-aluminum rocks at Jezero crater [0.03%]
“火星杰泽罗陨石坑发现高铝岩石表明火星早期曾经历强烈的改造事件”

C Royer et al.
The NASA Perseverance rover discovered light-toned float rocks scattered across the surface of Jezero crater that are particularly rich in alumina ( ~ 35 wt% Al2O3) and depleted in other major elements (except silica). These unique float ro...
A likely role for stratification in long-term changes of the global ocean tides [0.03%]
分层在全球海洋潮汐长期变化中的可能作用

Lana Opel
Stratification-that is, the vertical change in seawater density-exerts a subtle control on the energetics and thus the surface elevation of barotropic (depth independent) flows in the ocean. Changes in stratification therefore provide a pla...
Lunar ejecta origin of near-Earth asteroid Kamo'oalewa is compatible with rare orbital pathways [0.03%]
月球抛射物起源的近地小行星Kamo'oalewa与罕见轨道路径一致

Jose Daniel Castro-Cisneros
Near-Earth asteroid, Kamo'oalewa (469219), is one of a small number of known quasi-satellites of Earth; it transitions between quasi-satellite and horseshoe orbital states on centennial timescales, maintaining this dynamics over megayears. ...
Catastrophic impact of extreme 2019 Indonesian peatland fires on urban air quality and health [0.03%]
2019年印度尼西亚泥煤火灾对城市空气质量及健康产生的严重影响
Mark J Grosvenor,Vissia Ardiyani,Martin J Wooster et al.
Mark J Grosvenor et al.
Tropical peatland fires generate substantial quantities of airborne fine particulate matter (PM2.5) and in Indonesia are intensified during El Niño-related drought leading to severe air quality impacts affecting local and distant populatio...
Abiotic and biotic-controlled nanomaterial formation pathways within the Earth's nanomaterial cycle [0.03%]
地球纳米材料循环中的非生物和生物学控制的纳米材料形成途径

Michael Schindler
Nanomaterials have unique properties and play critical roles in the budget, cycling, and chemical processing of elements on Earth. An understanding of the cycling of nanomaterials can be greatly improved if the pathways of their formation a...

Filomena Silva et al.
Plastics pollution, persistent chemical contamination and inadequately treated wastewater are three key aspects that hinder access to safe and affordable water for all. We argue that a strong priority on pollution avoidance, research for re...
Demographics shape public preferences for carbon dioxide removal and solar geoengineering interventions across 30 countries [0.03%]
人口因素影响了30个国家公众对二氧化碳清除和太阳能地球工程干预的偏好
Benjamin K Sovacool,Darrick Evensen,Chad M Baum et al.
Benjamin K Sovacool et al.
Climate intervention technologies such as carbon dioxide removal and solar geoengineering are becoming more actively considered as solutions to global warming. The demographic aspects of the public serve as a core determinant of social vuln...
Universal neural networks for real-time earthquake early warning trained with generalized earthquakes [0.03%]
基于广义地震进行训练的实时地震预警通用神经网络

Deep learning enhances earthquake monitoring capabilities by mining seismic waveforms directly. However, current neural networks, trained within specific areas, face challenges in generalizing to diverse regions. Here, we employ a data reco...
Spectral location for the universal scaling regime in Martian atmospheric turbulence [0.03%]
火星大气湍流中普遍标度律的谱位置
Miya C Y Coimbra,Manuel de la Torre Juárez,Beverley J McKeon et al.
Miya C Y Coimbra et al.
Atmospheric turbulence, irregular fluctuations of the fluid state, is studied on Mars. Universality of the turbulence spectrum underpins atmospheric models where computational requirements preclude full fidelity simulations of the smallest ...
Major distribution shifts are projected for key rangeland grasses under a high-emission scenario in East Africa at the end of the 21st century [0.03%]
高排放情景下东非关键草原牧草分布的大范围迁移发生在21世纪末
Martina Messmer,Sandra Eckert,Amor Torre-Marin Rando et al.
Martina Messmer et al.
Grassland landscapes are important ecosystems in East Africa, providing habitat and grazing grounds for wildlife and livestock and supporting pastoralism, an essential part of the agricultural sector. Since future grassland availability dir...
