    The impact of nature on children’s wellbeing

    Get PDF
    Engaging with nature has been found to be associated with various benefits, including benefits for physical health and self-reported well-being (e.g. Rogerson, Barton, Bragg, & Pretty, 2017). However, most of the research to date has been undertaken with adults and much less is known about the benefits to children. Here we report on a project funded by The Wildlife Trusts in which we undertook research to investigate what children felt they got from participating in outdoor activities

    Primary children’s views about appreciating, supporting, and learning about nature

    Biology education aims to inspire interest, curiosity, and understanding about the natural world, foster children’s interests and orientations towards supporting and protecting nature, and support children towards biology-related careers (including those involving nature and animals). However, it remains less clear how these views might associate with different aspects of education and life. In order to gain new insights, 679 children in England (between 7 and 10 years old) were surveyed. The questionnaire included established measures for views about nature and learning, alongside new areas. The analysis applied predictive modelling to reveal independent associations between the children’s views. The children’s appreciation of nature and affinities towards animals were two of the strongest positive predictors of their interest in learning about nature, which was the strongest positive predictor of their aspirations towards careers involving nature or animals. Other findings highlighted the importance of nature-related activities and also children’s wider educational contexts and views. Watching nature-related media positively predicted children’s interest in learning about nature, while reading books about nature or wildlife positively predicted children’s aspirations towards careers involving nature or animals. Children’s confidence and enjoyment in their schoolwork positively predicted their appreciation of nature and also their interest in learning about nature

    Chemical and Biological Explorations of the Family of CC-1065 and the Duocarmycin Natural Products.

    Get PDF
    yesCC-1065, the duocarmycins and yatakemycin are members of a family of ultrapotent antitumour antibiotics that have been the subject of extensive investigations due to their mode of action and potential in the design of new anticancer therapeutics. The natural products and their analogues exert their effects through a sequence selective alkylation of duplex DNA in the minor groove at the N3 of adenine. An understanding of their structure and its effect on biological activity has been derived through chemical synthesis and has also generated new potential lead compounds. These studies form the first section of the review. The desire to progress these compounds to clinic has also led to studies of bioconjugation and prodrug formation and this is discussed in the second section of the review. The combination of synthesis with key biological experiments is a powerful tool to define the requirements for the development of natural products as potential therapeutic agents. The studies described herein form an excellent paradigm for the study and development of other natural products.EPSRC, Yorkshire Cancer Research, Big C Cancer Research, UCB Pharm

    1. Climate and soil: The annual rainfall was just below average and the weather was particularly dry durinq the early growing period. There was heavy rainfall in September which adversely affected the September sown rabi pigeonpeas..

    Field screening of pigeonpeas for tolerance to soil salinity

    A total of 47 lines (30 advanced breeding lines and 11 varieties of Cajanus cajan and six Atylosia species) were tested under naturally saline field conditions. Survival of most lines was intermediate between that of the tolerant and susceptible standard varieties, C11 and Hy3C, respectively. Four selections from ICP7623, one each from ICP7118, ICP7182 and ICP7035, the local variety ST1 and Atylosia scarabaeoides showed better survival than the tolerant standar

    Solid-phase synthesis of duocarmycin analogues and the effect of C-terminal substitution on biological activity

    Get PDF
    YesThe duocarmycins are potent antitumour agents with potential in the development of antibody drug conjugates (ADCs) as well as being clinical candidates in their own right. In this paper, we describe the synthesis of a duocarmycin monomer (DSA) that is suitably protected for utilisation in solid phase synthesis. The synthesis was performed on a large scale and the resulting racemic protected Fmoc-DSA subunit was separated by supercritical fluid chromatography (SFC) into the single enantiomers. Application to solid phase synthesis methodology gave a series of monomeric and extended duocarmycin analogues with amino acid substituents. The DNA sequence selectivity was similar to previous reports for both the monomeric and extended compounds. The substitution at the C-terminus of the duocarmycin caused a decrease in antiproliferative activity for all of the compounds studied. An extended compound containing an alanine at the C-terminus was converted to the primary amide or to an extended structure containing a terminal tertiary amine but this had no beneficial effects on biological activity.MJS was funded by Novartis and UEA.

    Intramolecular thermal stepwise [2 + 2] cycloadditions: investigation of a stereoselective synthesis of [n.2.0]-bicyclolactones

    Get PDF
    YesFused cyclobutanes are found in a range of natural products and formation of these motifs in a straightforward and easy manner represents an interesting synthetic challenge. To this end we investigated an intramolecular variant of the thermal enamine [2 + 2] cyclisation, developing a diastereoselective intramolecular enamine [2 + 2] cyclisation furnishing δ lactone and lactam fused cyclobutenes in good yield and excellent diastereoselectivity.The work was funded by Yorkshire Cancer Researc

    The Contribution of Natural History Museums to Science Education

    This is a report of a project titled ‘The Contribution of Natural History Museums to Science Education’, funded by the Wellcome Trust and ESRC with a Phase 1 grant from the Science Learning+ initiative. The project explored how Natural History Museums (NHMs) and schools can complement one another to maximise learning among school-age learners, and researched the long-term benefits to learning and engagement with science that NHMs can provide. During the course of our work, our team, which consisted of museum professionals and academics in the UK and the US, worked in the UK and the US with practitioners in NHMs and with school teachers and students. Our conclusions, as summarised in this Executive Summary, fall into two areas, one to do with the provision by museums of learning experiences for students, the other to do with how NHMs assess the effects of their provision. While our focus is on NHMs, a number of our conclusions apply more generally
