Biomass carbon emissions from nickel mining have significant implications for climate action.
Nat Commun

School of the Environment, The University of Queensland, St. Lucia, QLD, Australia.
Global nickel demand is projected to double by 2050 to support low-carbon technologies and renewable energy production. However, biomass carbon emissions from clearing vegetation for nickel mining are rarely included in corporate sustainability reports or considered in mineral sourcing decisions. Here, we compiled data for 481 nickel mines and undeveloped deposits to show that the footprint of nickel mining could be 4 to 500 times greater than previously reported (depending on the mine site), and thus the environmental impacts of nickel products, including batteries, have been underestimated to date.

A voltage-gated sodium channel (VGSC) plays a crucial role in insect electrical signals, and it is a target for various naturally occurring and synthesized neurotoxins, including pyrethroids and dichlorodiphenyltrichloroethane. The type of agent is typically widely used to prevent and control sanitary and agricultural pests. The perennial use of insecticides has caused mutations in VGSCs that have given rise to resistance in most insects.

Ultra-rapid insulin lispro is an innovative insulin analogue designed to achieve rapid onset and short duration of action, aimed at optimizing glycemic control in patients with diabetes. This was a double-blind, randomized, 2-period, crossover clamp study to evaluate the pharmacokinetics (PK) and pharmacodynamics (PD), along with safety profiles, of a potential biosimilar ultra-rapid insulin lispro compared to the reference product in healthy White men. A total of 35 healthy volunteers completed hyperinsulinemic euglycemic clamp procedures across both study periods.

Copper compounds with artificial metallo-nuclease (AMN) activity are mechanistically unique compared to established metallodrugs. Here, we describe the development of a new dinuclear copper AMN, Cu2-BPL-C6 (BPL-C6 = bis-1,10-phenanthroline-carbon-6), prepared using click chemistry that demonstrates site-specific DNA recognition with low micromolar cleavage activity. The BPL-C6 ligand was designed to force two redox-active copper centres-central for enhancing AMN activity-to bind DNA, via two phenanthroline ligands separated by an aliphatic linker.

Introduction: The environmental impact of on-site conferences, with air travel as the primary contributor to greenhouse gas emissions, has prompted a surge in research in recent years. The objective of this report is to raise awareness and stimulate transformation in the organisation of meetings of the European Health Psychology Society (EHPS).
Methods: We conducted estimations of travel-related COeq emissions of EHPS conferences in 2019, 2022, and 2023, and performed projections for 2024 and 2025.
