Deep ocean microbial communities produce more stable dissolved organic matter through the succession of rare prokaryotes

Author(s): LaBrie R; Péquin B; Fortin St-Gelais N; Yashayaev I; Cherrier J; Gélinas Y; Guillemette F; Podgorski DC; Spencer RGM; Tremblay L; Maranger R;

The microbial carbon pump (MCP) hypothesis suggests that successive transformation of labile dissolved organic carbon (DOC) by prokaryotes produces refractory DOC (RDOC) and contributes to the long-term stability of the deep ocean DOC reservoir. We tested the MCP by exposing surface water from ...

Can Science-Based Targets Make the Private Sector Paris-Aligned? A Review of the Emerging Evidence

Author(s): Bjørn A; Tilsted JP; Addas A; Lloyd SM;

Purpose of review: Companies increasingly set science-based targets (SBTs) for reducing greenhouse gas emissions. We review literature on SBTs to understand their potential for aligning corporate emissions with the temperature goal of the Paris Agreement. Recent findings: SBT adoption by larger, more visible companies in high-income countries has accel ...

Development and testing of a SOSM approach to examine the natural attenuation of oil spillage on shorelines

Author(s): Yang Z; Chen Z;

Understanding the fate and behavior of spilled oil on the shoreline is crucial for helping decision-makers make trade-offs between natural attenuation and shoreline treatments. In this study, primary processes of oil attenuation and translocation on the shoreline, including penetration, washout, and biodegradation, have been considered to develop a nume ...

Gold Nano-Bio-Interaction to Modulate Mechanobiological Responses for Cancer Therapy Applications

Author(s): Sohrabi Kashani A; Larocque K; Piekny A; Packirisamy M;

In the present study, we investigate the mechanobiological responses of human lung cancer that may occur through their interactions with two different types of gold nanoparticles: nanostars and nanospheres. Hyperspectral images of nanoparticle-treated cells revealed different spatial distributions of nanoparticles in cells depending on their morphology, ...

Acetate and hypertonic stress stimulate vacuole membrane fission using distinct mechanisms

Author(s): Gokbayrak ZD; Patel D; Brett CL;

Vacuoles in plants and fungi play critical roles in cell metabolism and osmoregulation. To support these functions, vacuoles change their morphology, e.g. they fragment when these organisms are challenged with draught, high salinity or metabolic stress (e.g. acetate accumulation). In turn, morphology reflects an equilibrium between membrane fusion and f ...

Utilization of a biosurfactant foam/nanoparticle mixture for treatment of oil pollutants in soil

Author(s): Vu KA; Mulligan CN;

Oil contamination has become a primary environmental concern due to increased exploration, production, and use. When oil enters the soil, it may attach or adsorb to soil particles and stay in the soil for an extended period, contaminating the soil and surrounding areas. Nanoparticles have been widely used for the treatment of organic pollutants in the s ...

Household income and maternal education in early childhood and risk of overweight and obesity in late childhood: Findings from seven birth cohort studies in six high-income countries

Author(s): White PA; Awad YA; Gauvin L; Spencer NJ; McGrath JJ; Clifford SA; Nikiema B; Yang-Huang J; Goldhaber-Fiebert JD; Markham W; Mensah FK; van Grieken A; Raat H; Jaddoe VWV; Ludvigsson J; Faresjö T;

Background/objectives: This study analysed the relationship between early childhood socioeconomic status (SES) measured by maternal education and household income and the subsequent development of childhood overweight and obesity. Subjects/methods: Data from seven population-representative pro ...

Invariance, Encodings, and Generalization: Learning Identity Effects With Neural Networks

Author(s): Brugiapaglia S; Liu M; Tupper P;

Often in language and other areas of cognition, whether two components of an object are identical or not determines if it is well formed. We call such constraints identity effects. When developing a system to learn well-formedness from examples, it is easy enough to build in an identity effect. But can identity effects be learned from the data without e ...

On the Origin of Sugar Handedness: Facts, Hypotheses and Missing Links-A Review

Author(s): Martínez RF; Cuccia LA; Viedma C; Cintas P;

By paraphrasing one of Kipling's most amazing short stories (How the Leopard Got His Spots), this article could be entitled "How Sugars Became Homochiral". Obviously, we have no answer to this still unsolved mystery, and this perspective simply brings recent models, experiments and hypotheses into the homochiral homogeneity of sugars on earth. We sh ...

Effect of oxidative aging of biochar on relative distribution of competitive adsorption mechanism of Cd2+ and Pb2

Author(s): Wang Z; Geng C; Bian Y; Zhang G; Zheng C; An C;

In this study, aged biochar (CCB350 and CCB650) were obtained from pyrolysis of corn stalk biochar (CB350 and CB650) at the degree of 350 °C and 650 °C by artificial oxidation with hydrogen peroxide (H2O2). Also, the mechanism of Pb2+ and Cd2+ on fresh and aged biochars was analyzed qualitatively and quantitatively by batch adsorption experiments combin ...

Exploring the characteristics, performance, and mechanisms of a magnetic-mediated washing fluid for the cleanup of oiled beach sand

Author(s): Yue R; An C; Ye Z; Chen X; Lee K; Zhang K; Wan S; Qu Z;

In the present study, an innovative, environmentally benign recyclable, and magnetically mediated surface washing fluid based on water-dispersible magnetite nanoparticles has been designed and investigated for the cleanup of oiled beach sand. The characterization results showed that the as-prepared magnetite nanoparticles had a spherical morphology with ...

The effect of phasic versus combined neuromuscular electrical stimulation using the StimaWELL 120MTRS system on multifidus muscle morphology and function in patients with chronic low back pain: a randomized controlled trial protocol

Author(s): Fortin M; Wolfe D; Dover G; Boily M;

Background: Neuromuscular electrical stimulation (NMES) is used to improve muscle strength clinically when rehabilitating various musculoskeletal disorders. However, the effects of NMES on muscle morphology and function in individuals with non-specific chronic low back pain (CLBP) have scarcely been investigated. Although research links deficits in the ...
