Influence of long-term anthropogenic nitrogen input and its legacy on riverine output. #water #pollution #nitrogen #anthropogenic #river nature.com/articles/s41598-025

NatureInfluence of long-term anthropogenic nitrogen input and its legacy on riverine output - Scientific ReportsThe accelerated accumulation of anthropogenic nitrogen input and nitrogen legacies (NL) is a primary driver for persistently high nitrogen loads in rivers. Understanding the impact of nitrogen inputs and NL on river nitrogen export (RNE) is critical for improving water quality. This study employs the net anthropogenic nitrogen input (NANI) approach and export coefficient model (ECM), coupled with remote sensing data, to analyze nitrogen input dynamics, total nitrogen export (TNE), and NL from 1949 to 2021 in China’s Dongjiang River watershed. Results indicate that NANI peaked in 2017 while TNE and NL continued to grow. Over the 73 years, NANI grew rapidly from 1949 to 1992, exhibited fluctuating growth from 1993 to 2021, and reached its maximum value (6743 kg·km−2·y−1) in 2017. Meanwhile, Total nitrogen output and NL maintained a continuous growth trend, with NL contributing approximately 46.5% to RNE from 1986 to 2021. Despite reduced NANI, recent nitrogen inputs remain a major factor influencing TNE. Spatial analysis reveals that nitrogen management should prioritize agricultural practices in upstream and urban pollution control in downstream.

Nitrogen Dropping Cobalt Strike – A Combination of 'Chemical Elements'

The Nitrogen ransomware group has expanded its operations from North America to Africa and Europe since September 2024. They utilize malvertising tactics, disguising malicious payloads as legitimate software like WinSCP. The group employs DLL sideloading for initial access, followed by Cobalt Strike for lateral movement and post-exploitation activities. The analysis reveals their use of a compromised host as a pivot system and attempts to cover tracks by clearing Windows logs. The investigation uncovered Cobalt Strike configurations through pattern analysis, byte-level XOR decryption, and custom YARA rules. Crash dump analysis using Windows Error Reporting artifacts and WinDBG proved crucial in identifying in-memory indicators of Cobalt Strike beacons and related structures.

Netherlands delays nitrogen emissions target, defying its own judges and the EU

The Netherlands is rolling back its nitrogen reduction targets, setting the stage for a showdown with its own judges and Brussels over one of Europe’s most contentious environmental issues

The Netherlands delays its nitrogen emissions target, defying its own judges and the EU.

The Dutch government confirmed it will push back its deadline to halve nitrogen emissions from 2030 to 2035, defying a recent court order.

With its high-density farming, the Netherlands has long been ground zero for Europe’s nitrogen crisis. The country ranks among the EU's worst for nitrogen pollution per hectare.

🌍🪨Did you know some metamorphic #rocks, called metabasic rocks, are an enormous source of #nitrogen being carried deep into the Earth through subduction? A deep nitrogen (N) cycling study by Ananya Mallik, Anna Rebaza, Paul Kapp, Long Li, Yifan Du, Ahmed Al Shams, Emily Cooperdock unveiled these and more. Check out their dataset and article at doi.org/10.25422/azu.data.2350 and doi.org/10.1016/j.gca.2023.10.. Image: Stockcake #OpenData #OpenScience #Geosciences #UniversityofArizona

#Whale pee moves vital nutrients thousands of miles
'We often think of plants as the lungs of the planet. Animals are the circulatory system.’
Some new research found that great #whales—including right whales, gray whales, and humpbacks—transport roughly 4,000 tons of #nitrogen to low-nutrient coastal areas in the tropics and subtropics every single year. Described as the “great whale pee funnel.”
