Roots and Associated Fungi Drive Long-Term Carbon Sequestration in Boreal Forest
Boreal forest soils function as a terrestrial net sink in the global carbon cycle. The prevailing dogma has focused on aboveground plant litter as a principal source of soil organic matter. Using C-14 bomb-carbon modeling, we show that 50 to 70% of stored carbon in a chronosequence of boreal forested islands derives from roots and root-associated microorganisms. Fungal biomarkers indicate impaired
Estrogen receptor alpha is upregulated and metastasis inhibited in a murine breast cancer model following treatment with the novel Wnt-5a derived-hexapeptide, Foxy-5
Company norms affect which traits are preferred in job candidates and may cause employment discrimination
This study investigated a possible mechanism behind employment discrimination. Participants completed a recruitment task where emphasis on cohesion (employees should “fit in”) vs. fairness (everybody should be treated equally) was manipulated by describing the norms of a fictitious company differently. There was a comparatively stronger preference in the cohesion condition for traits and interview

Global priorities for marine biodiversity conservation.
In recent decades, many marine populations have experienced major declines in abundance, but we still know little about where management interventions may help protect the highest levels of marine biodiversity. We used modeled spatial distribution data for nearly 12,500 species to quantify global patterns of species richness and two measures of endemism. By combining these data with spatial inform
Robust Camera Tracking by Combining Color and Depth Measurements
One of the major research areas in computer vision is scene reconstruction from image streams. The advent of RGB-D cameras, such as the Microsoft Kinect, has lead to new possibilities for performing accurate and dense 3D reconstruction. There are already well-working algorithms to acquire 3D models from depth sensors, both for large and small scale scenes. However, these methods often break down w
Rain-season trends in precipitation and their effect in different climate regions of China during 1961-2008
Using high-quality precipitation data from 524 stations, the trends of a set of precipitation variables during the main rain season (May-September) from 1961 to 2008 for different climate regions in China were analysed. However, different characteristics were displayed in different regions of China. In most temperate monsoon regions (north-eastern China), total rain-season precipitation and precip

Cognitive Manic Symptoms in Bipolar Disorder Associated with Polymorphisms in the DAOA and COMT Genes
Introduction: Bipolar disorder is characterized by severe mood symptoms including major depressive and manic episodes. During manic episodes, many patients show cognitive dysfunction. Dopamine and glutamate are important for cognitive processing, thus the COMT and DAOA genes that modulate the expression of these neurotransmitters are of interest for studies of cognitive function. Methodology: Focu
HIV-1, HIV-2 and other Sexually Transmitted Infections in Guinea-Bissau, West Africa
Popular Abstract in Swedish Humant immunbristvirus (HIV) orsakar förvärvat immunbristtillstånd (AIDS). HIV/AIDS-epidemin har hittills innefattat över 60 miljoner människor som har infekterats och över 30 miljoner av dessa har avlidit i AIDS. HIV-infektion smittar via blod, sexuellt och från mor till barn vid graviditet eller via bröstmjölk. Vid infektion infogas virusets arvsmassa i den infekteradHIV-1 is dominating the global HIV pandemic, while HIV-2 is mainly confined to West Africa. The highest HIV-2 prevalence figures have been reported from Guinea-Bissau. While HIV-1 infection almost invariably leads to progressive immune dysfunction and AIDS, HIV-2 infection is characterised by a smaller proportion of individuals with disease progression to AIDS. In order to monitor the long-term e
The risk/no-risk rhetoric of environmental impact assessments (EIA): The case of off-shore wind farms in Sweden
Risk is a key topic in the communication between developers of infrastructure projects, permit-granting authorities, and civil society. The nature of risk communication is contested among academics, however. Whereas some scholars conceive of risk communication as a matter of effectively communicating expert knowledge on factual matters to the public, others emphasize the role of symbolic construct
Structure and Potential Cellular Targets of HAMLET-like Anti-Cancer Compounds made from Milk Components
The HAMLET family of compounds (Human Alpha-lactalbumin Made Lethal to Tumours) was discovered during studies on the properties of human milk, and is a class of protein-lipid complexes having broad spectrum anti-cancer, and some specific anti-bacterial properties. The structure of HAMLET-like compounds consists of an aggregation of partially unfolded protein making up the majority of the compound'

Temperature-responsive inclusion complex of cationic PNIPAAM diblock copolymer and gamma-cyclodextrin
Aqueous mixtures of gamma-cyclodextrin (gamma-CD) and the thermosensitive cationic diblock copolymer poly(N-isopropylacrylamide)-b-poly(3-acrylamidopropyl)trimethylammonium chloride (PNIPAAM(24)-b-PAMPTAM(+)(9)) or the PNIPAAM homopolymer PNIPAAM(47) have been investigated using various experimental methods. Solid g-CD-polymer inclusion complexes (pseudopolyrotaxanes) form at ambient temperatures
Challenging Packaging Limits and Infectivity of Phage λ
The terminase motors of bacteriophages have been shown to be among the strongest active machines in the biomolecular world, being able to package several tens of kilobase pairs of viral genome into a capsid within minutes. Yet, these motors are hindered at the end of the packaging process by the progressive buildup of a force-resisting packaging associated with already packaged DNA. In this experi
Fluorescence Time-lapse Imaging of the Complete S. venezuelae Life Cycle Using a Microfluidic Device.
Live-cell imaging of biological processes at the single cell level has been instrumental to our current understanding of the subcellular organization of bacterial cells. However, the application of time-lapse microscopy to study the cell biological processes underpinning development in the sporulating filamentous bacteria Streptomyces has been hampered by technical difficulties. Here we present a
Cultural Trauma, Ritual and Healing
In this chapter I will discuss the effects of agency loss, cultural trauma and healing, by focusing on the impact the boarding schools, the so called residential school, had and still has on contemporary Cana-dian Mi’kmaq Native identity, drawing on interviews from one of my fieldworks conducted on the island Cape Breton, Nova Scotia.
