‘Scaling Laws for Two-Dimensional Dendritic Crystal Growth in a Narrow Channel’
“We investigate analytically and computationally the dynamics of 2D needle crystal growth from the melt in a narrow channel. Our analytical theory predicts that, in the low supersaturation limit, the growth velocity V decreases in time t as a power law V∼t−2/3, which we validate by phase-field and dendritic-needle-network simulations.” See the full list of authors and read this pre-print at ArXiv.

Coastal upwelling helps delicate species survive
This article is an important addition to our understanding of species abundance and distribution—a subject becoming ever more important with ongoing climate change. For this study, researchers used “wavelet analysis” to examine sixteen intertidal zones along the the coast of Europe. Results show that “upwelling”—a process that brings deep, cold water to the surface—produces refuges for thermally delicate species by mitigating rising temperatures. See the full list of authors and read “Coastal upwelling generates cryptic temperature refugia” in Nature.

‘Effect of Dissolved Humic Acids and Coated Humic Acids on Tetracycline Adsorption by K₂CO₃-Activated Magnetic Biochar’
“Humic acids (HAs) widely exist in water environment, and has an important impact on the adsorption of pollutants. Herein, HAs (both dissolved and coated) was employed to assess the effect on the removal of the organic contaminant tetracycline (TC) by K2CO3 modified magnetic biochar (KMBC). Results showed that low concentration of dissolved HAs promoted TC removal, likely due to a bridging effect, while higher concentration of dissolved HAs inhibited TC adsorption because of the competition of adsorption sites on KMBC.” Find the paper and the full list of authors in Scientific Reports.

Bribery and the ‘new normal’ in transition economies
“Recent research examines 310 privately owned small and medium-sized companies from 22 transition economies in Eastern Europe and Former Soviet Republics to see how the payment of bribes affects entrepreneur perceptions of the business environment. Those who more frequently pay bribes create a “new normal” business environment that is perceived as increasingly harsh. However, for entrepreneurs who infrequently bribe, their ‘new normal’ is likely to be perceived as more supportive of business.” Read “How Bribe-Payers Create a ‘New Normal’ of Corruption in Transition Economies” and see the full list of authors at the Insights @ Center for Emerging Markets.

Will eating (certain) plants increase cognitive health in children? This study hopes to find out
With “Enhancing children’s cognitive function and achievement through carotenoid consumption: The Integrated Childhood Ocular Nutrition Study (iCONS) protocol,” researchers hope to discover the effect of carotenoids (plant pigments) on preadolescence. Carotenoids have been shown to positively impact cognition in adults, and this proposed, placebo-controlled, double-blind study will by the first to study the effect of two of these pigments—lutein and zeaxanthin—on preadolescents. Their hypothesis states, “children receiving the carotenoid supplement will exhibit greater gains in cognitive function and achievement relative to the waitlist placebo group.” Find the full list of authors and their research in Contemporary Clinical Trials.

Collecting the microbiomes of ‘blue carbon’ ecosystems
So-called “blue carbon” ecosystems are marine environments that serve as valuable carbon sinks, and are thus vital aids against climate change. Their effectivity, however, “is strongly influenced by the metabolism of soil-associated microbes.” As genetic sequencing technologies continue to improve, scientists can collect “tremendous amounts of data on what taxa comprise belowground microbial assemblages.” This paper provides a “toolbox… for the acquisition, management, and integration of Blue Carbon-associated sequencing data and metadata to potentially elucidate novel mechanisms behind Blue Carbon dynamics.” Read “Pathways for Understanding Blue Carbon Microbiomes with Amplicon Sequencing,” and see the full list of authors in Microorganisms.
