Host-derived organic acids enable gut colonization of the honey bee symbiont Snodgrassella alvi

Diverse bacteria can colonize the animal gut using dietary nutrients or by engaging in microbial crossfeeding interactions. Less is known about the role of host-derived nutrients in enabling gut bacterial colonization. Here we examined metabolic interactio ...

Architecture of a decentralised decision support system for futuristic beehives

Francesco Mondada, Robert Matthew Mills

Honeybees are essential to human society, providing pollination services globally as well as producing honey and other valuable products. Effective management of apiaries should not only rely on beekeeper knowledge and skill, but also incorporate new infor ...

Comparative techno-economic and energy analyses of integrated biorefinery processes of furfural and 5-hydroxymethylfurfural from biomass residue

François Maréchal

For efficient feedstock and energy utilization, integrated biorefinery processes are applied to furfural production from bagasse to convert furfural residue into 5-hydroxymethylfurfural (HMF)-an important intermediate building block for the production of v ...

Radical-free hyperpolarized MRI using endogenously occurring pyruvate analogues and UV-induced nonpersistent radicals

Rolf Gruetter, Andrea Capozzi, Josefina Adriana Maria Bastiaansen, Hikari Ananda Infinity Yoshihara, Alice Radaelli, Claudia Christina Zanella, Lionel Pierre Arn

It was recently demonstrated that nonpersistent radicals can be generated in frozen solutions of metabolites such as pyruvate by irradiation with UV light, enabling radical-free dissolution dynamic nuclear polarization. Although pyruvate is endogenous, the ...

Unsteady flow and particle migration in dense, non-Brownian suspensions

Matthieu Wyart

We present experimental results on dense corn-starch suspensions as examples of non-Brownian, nearly hard particles that undergo continuous and discontinuous shear thickening (DST) at intermediate and high densities, respectively. Our results offer strong ...

Conversion of biomass into value-added chemicals

Sviatlana Siankevich

Green house gas emissions, the depleting of non-renewable resources, and poor waste management have a detrimental environmental and socioeconomic impact. Consequantly, the development of alternative processes that alleviate these problems is imperative. Ap ...

Probable nature of higher-dimensional symmetries underlying mammalian grid-cell activity patterns

Alexander Mathis

Lattices abound in nature—from the crystal structure of minerals to the honey-comb organization of ommatidia in the compound eye of insects. These arrangements provide solutions for optimal packings, efficient resource distribution, and cryptographic proto ...

Enhanced Conversion of Carbohydrates to the Platform Chemical 5-Hydroxymethylfurfural Using Designer Ionic Liquids

Paul Joseph Dyson, Rosario Scopelliti, Gabor Laurenczy, Zhaofu Fei, Ning Yan, Sviatlana Siankevich

5-Hydroxymethylfurfural (HMF) is a key platform chemical that may be obtained from various cellulosic (biomass) derivatives. Previously, it has been shown that ionic liquids (ILs) facilitate the catalytic conversion of glucose into HMF. Herein, we demonstr ...

Multilevel Correlations in the Biological Phosphorus Removal Process: from Bacterial Enrichment to Conductivity-Based Metabolic Batch Tests and Polyphosphatase Assays

Christof Holliger, Julien Maillard, Alessandro Brovelli, David Gregory Weissbrodt, Alexandre Chabrelie, Jonathan May

Enhanced biological phosphorus removal (EBPR) from wastewater relies on the preferential selection of active polyphosphate-accumulating organisms (PAO) in the underlying bacterial community continuum. Efficient management of the bacterial resource requires ...

Shear Thickening Fluid Impregnated Foam Composites for Vibration Control and Impact Protection

Mathieu Soutrenon

Highly concentrated suspensions of silica particles present shear thickening properties, shifting from a low to a high viscosity state, instantly and reversibly at a critical shear rate. Their viscosity increases by up to 3 orders of magnitude, changing fr ...
