The frequency and intensity of wildfires in the Arctic has been increasing due to climate change. However, little is known about the effects of fire intensity on carbon dioxide (CO2) exchange in arctic tundra ecosystems. To investigate this, we conducted an experimental fire with different burn intensities (low intensity, high intensity, and unburned control) and measured surface daytime CO2 fluxes

We investigate how ancient humans ran and hear from climate scientists who are rising to the challenges of an impending Trump presidency.

Recently, the bilayer nickelate La3Ni2O7 has been discovered as a new superconductor with transition temperature Tc near 80 K under high pressure1–3. Despite extensive theoretical and experimental work to understand the nature of its superconductivity4–29, the requirement of extreme pressure restricts the use of many experimental probes and limits its application potential. Here, we present signatures

The evolution of the lunar dynamo is essential for deciphering the deep interior structure, thermal history, and surface environment of the Moon1-4. Previous palaeomagnetic investigations on samples returned from the nearside of the Moon have established the general variation of the lunar magnetic field5-7. However, limited spatial and temporal palaeomagnetic constraints leave the evolution of the

Introduction Optimizing fruit quality and yield in agriculture requires accurately monitoring leaf nitrogen (N) status spatially and temporally throughout the growing season. Standard remote sensing approaches for assessing leaf N rely on proxies like vegetation indices or leaf chlorophyll a + b (Cab) content. However, limitations exist due to the Cab-N relationship’s saturation and early nutrient

The first stage in the precision agriculture cycle has been a vital study area in recent years because it allows soil testing followed by data analysis. In this stage, a strategic delineation of site-specific management zones acquires a particular interest because it enables site-specific treatment to improve crop yield by efficiently using the input of resources. The delineation of site-specific management

The global attention to the utilization of unmanned aerial vehicle remote sensing drones in crop disease-wide detection has led to the urgent need to find an adapted model for different environmental conditions. Therefore, the current study has focused on spatiotemporal usage of different multispectral cameras in acquiring spectral reflectance models of in-field rice bacterial blight stresses. Where

Turbulence governs many atmospheric processes including mixing, transport, and energy transfer. Consequently, there is a strong need for the examination and validation of existing turbulence theories. The HOckey-Stick Transition (HOST) hypothesis was proposed to challenge traditional understanding of near-surface turbulence processes derived from Monin-Obukhov Similarity Theory (MOST). Within the MOST

Carbon allocation in vegetation, particularly to leaves and roots responsible for resource assimilation, plays a crucial role in regulating the global carbon cycle and is highly sensitive to environmental changes. However, due to the limited observational data, the response of carbon allocation—particularly between resource-acquiring organs—to rapid global environmental changes remains unclear for

Proteins could serve as biomarkers for senescent cells, which have stopped dividing but have not yet died.

3D models of Australopithecus afarensis suggest the muscular adaptations that made modern humans better runners.

Three researchers talk about life in companies and the key to unlocking opportunities.

Human treponemal infections are caused by a family of closely related Treponema pallidum that give rise to the diseases yaws, bejel, pinta and, most famously, syphilis1. Debates on both a common origin for these pathogens and the history of syphilis itself has weighed evidence for the “Columbian hypothesis”2, which argues for an American origin, against that for the “pre-Columbian hypothesis”3, which
