Exploring the transfer of recent plant photosynthates to soil microbes: mycorrhizal pathway vs direct root exudation
Plants rapidly release photoassimilated carbon (C) to the soil via direct root exudation and associated mycorrhizal fungi, with both pathways promoting plant nutrient availability. This study aimedExpand

Exploration of Inorganic C and N Assimilation by Soil Microbes with Time-of-Flight Secondary Ion Mass Spectrometry
ABSTRACT Stable C and N isotopes have long been used to examine properties of various C and N cycling processes in soils. Unfortunately, relatively large sample sizes are needed for accurate gasExpand

In Situ Mapping of Nutrient Uptake in the Rhizosphere Using Nanoscale Secondary Ion Mass Spectrometry1[OA]
Plant roots and microorganisms interact and compete for nutrients within the rhizosphere, which is considered one of the most biologically complex systems on Earth. Unraveling the nitrogen (N) cycleExpand

Visualising gold inside tumour cells following treatment with an antitumour gold(I) complex.
Gold(I) phosphine complexes, such as [Au(d2pype)(2)]Cl, (1, where d2pype is 1,2-bis(di-2-pyridyl phosphinoethane)), belong to a class of promising chemotherapeutic candidates that have been shown toExpand

Nanoscale analysis of pyritized microfossils reveals differential heterotrophic consumption in the ∼1.9-Ga Gunflint chert
The 1.88-Ga Gunflint biota is one of the most famous Precambrian microfossil lagerstätten and provides a key record of the biosphere at a time of changing oceanic redox structure and chemistry. Here,Expand

Differentiation of Spores of Bacillus subtilis Grown in Different Media by Elemental Characterization Using Time-of-Flight Secondary Ion Mass Spectrometry
ABSTRACT We demonstrate the use of time-of-flight secondary ion mass spectrometry (TOF-SIMS) in a forensics application to distinguish Bacillus subtilis spores grown in various media based on theExpand

An isotopic perspective on growth and differentiation of Proterozoic orogenic crust: From subduction magmatism to cratonization
Abstract The in situ chemical differentiation of continental crust ultimately leads to the long-term stability of the continents. This process, more commonly known as ‘cratonization’, is driven byExpand

Nutrient cycling in early coral life stages: Pocillopora damicornis larvae provide their algal symbiont (Symbiodinium) with nitrogen acquired from bacterial associates
The waters surrounding coral reef ecosystems are generally poor in nutrients, yet their levels of primary production are comparable with those reported from tropical rain forests. One explanation ofExpand
