Darwin's bee-trap : The kinetics of Catasetum, a new world orchid

The orchid genera Catasetum employs a hair-trigger activated, pollen release mechanism, which forcibly attaches pollen sacs onto foraging insects in the New World tropics. This remarkable adaptation was studied extensively by Charles Darwin and he termed this rapid response "sensitiveness." Using high speed video cameras with a frame speed of 1000 fps, this rapid release was filmed and from the su

A meta-analysis of single visit pollination effectiveness comparing honeybees and other floral visitors

Premise: Many animals provide ecosystem services in the form of pollination including honeybees, which have become globally dominant floral visitors. A rich literature documents considerable variation in single visit pollination effectiveness, but this literature has yet to be extensively synthesized to address whether honeybees are effective pollinators. Methods: We conducted a hierarchical meta-

Digitalization of bookkeeping in small organization: The case of Sweden

Bookkeeping and accounting is a prevalent feature of small organizations, which has changed face quite substantially with the advent of personal computers and, later, the Internet. The emergence of digitalized accounting procedures has taken place in a nexus of different types of actors (e.g., software developers, accountancy firms and the businesses themselves), regulatory frameworks (e.g., bookk

Mode och medborgarskap : Hur scouterna och Svenska herrmoderådet samarbetade för att styra ungdomar genom stil under 1950- och 1960-talen

I slutet av 1950-talet inledde Sveriges Scoutförbund utbildningssatsningen Stilskolan vid några av landets industri- och lärlingsskolor. Utbildningen utmynnade i ett samarbete med Svenska herrmoderådet, där organisationerna såg en möjlighet att utbilda ungdomar i frågor som rörde uppträdande och värderingar. I den här artikeln undersöker vi mer specifikt hur Stilskolan sökte väcka intresse bland uIn the late 1950s, Sveriges Scoutförbund (the Swedish Scout Association) launched courses for vocational schools called Stilskolan (lit. ”Style school”). A few years later, the Scout Association (from 1960 known as Svenska Scoutförbundet, the Swedish Guide and Scout Association) entered into a partnership with the Swedish Men’s Fashion Council, which provided material for the courses. The organisa

Clinical and Preclinical Lung Transplantation in the aspects of improving outcome

Lung transplantation (LTx) is an established therapeutic option for end-stage pulmonary disease. However, it remains restricted by donor lung scarcity. Donor's lungs are rejected frequently due to severe lung damage caused by aspiration or neurogenic pulmonary oedema that can all lead to acute lung injury (ALI), and more severe acute respiratory distress syndrome (ARDS). Lung transplant patients f

A versatile laboratory setup for high resolution X-ray phase contrast tomography and scintillator characterization

BACKGROUND: X-ray micro-tomography (μCT) is a powerful non-destructive 3D imaging method applied in many scientific fields. In combination with propagation-based phase-contrast, the method is suitable for samples with low absorption contrast. Phase contrast tomography has become available in the lab with the ongoing development of micro-focused tube sources, but it requires sensitive and high-reso

Plasma levels of CCL21, but not CCL19, independently predict future coronary events in a prospective population-based cohort

BACKGROUND AND AIMS: The homeostatic chemokines CCL21 and CCL19 have been explored as biomarkers in cardiovascular disease prediction in patients with established cardiovascular disease, but associations between these chemokines and first-time coronary event incidence have not been investigated before. Here, we explored associations between CCL21 or CCL19 and first-time incident coronary events in

A Capability Definition and Assessment Framework for Countering Disinformation, Information Influence, and Foreign Interference

This report proposes a capability assessment framework for countering disinformation, information influence, and foreign interference. At present, much emphasis is placed on the capability to counter disinformation and other associated phenomena. However, few have attempted to systematically define what those countermeasures are, and how they could be placed within a single, coherent capability as

Modelling metastatic colonization of cholangiocarcinoma organoids in decellularized lung and lymph nodes

Cholangiocarcinoma (CCA) is a type of liver cancer with an aggressive phenotype and dismal outcome in patients. The metastasis of CCA cancer cells to distant organs, commonly lung and lymph nodes, drastically reduces overall survival. However, mechanistic insight how CCA invades these metastatic sites is still lacking. This is partly because currently available models fail to mimic the complexity
