Chirality is a fundamental property of life, making chiral sensing and analysis crucial to numerous scientific subfields of biology, chemistry, and medicine, and to the pharmaceutical, chemical, cosmetic, and food industries, constituting a market of 10s of billion , and growing. Despite the tremendous importance of chiral sensing, its application remains very limited, as chiroptical signals are typically very weak, preventing important biological and medical applications. Recently, the project-coordinating FORTH team has introduced a new form of Chiral-Cavity-based Polarimetry (CCP) for chiral sensing, which has three groundbreaking advantages compared to commercial instruments: (a) The chiroptical signals are enhanced by the number of cavity passes (typically ~1000); (b) otherwise limiting birefringent backgrounds are suppressed; (c) rapid signal reversals give absolute polarimetry measurements, not requiring sample removal for a null-sample measurement. Together, these advantages allow improvement in chiral detection sensitivity by 3-6 orders of magnitude (depending on instrument complexity and price). ULTRACHIRAL aims to revolutionize existing applications of chiral sensing, but also to instigate important new domains which require sensitivities beyond current limits, including: (1) measuring protein structure in-situ, in solution, at surfaces, and within cells and membranes, thus realizing the holy-grail of proteomics; (2) coupling to high performance liquid chromatography (HPLC) for chiral identification of the components of complex mixtures, creating new standards for the pharmaceutical and chemical analysis industries; (3) chiral analysis of human bodily fluids as a diagnostic tool in medicine; (4) measurement of single-molecule chirality, by adapting CCP to microresonators, which have already demonstrated single-molecule detection; and (5) real-time chiral monitoring of terpene emissions from individual trees and forests, as a probe of forest ecology.

Europe has become a global leader in optical-near infrared astronomy through excellence in space and ground-based experimental and theoretical research. While the major infrastructures are delivered through major national and multi-national agencies (ESO, ESA) their continuing scientific competitiveness requires a strong community of scientists and technologists distributed across Europes nations. OPTICON has a proven record supporting European astrophysical excellence through development of new technologies, through training of new people, through delivering open access to the best infrastructures, and through strategic planning for future requirements in technology, innovative research methodologies, and trans-national coordination. Europes scientific excellence depends on continuing effort developing and supporting the distributed expertise across Europe - this is essential to develop and implement new technologies and ensure instrumentation and infrastructures remain cutting edge. Excellence depends on continuing effort to strengthen and broaden the community, through networking initiatives to include and then consolidate European communities with more limited science expertise. Excellence builds on training actions to qualify scientists from European communities which lack national access to state of the art research infrastructures to compete successfully for use of the best available facilities. Excellence depends on access programmes which enable all European scientists to access the best infrastructures needs-blind, purely on competitive merit. Global competitiveness and the future of the community require early planning of long-term sustainability, awareness of potentially disruptive technologies, and new approaches to the use of national-scale infrastructures under remote or robotic control. OPTICON will continue to promote this excellence, global competitiveness and long-term strategic planning.

Glycosphingolipids are ubiquitous constituents of eukaryotic plasma membranes, and their sialylated derivatives, gangliosides, are the major class of glycoconjugates expressed by neurons. Deficiencies in their catabolic pathways give rise to a large and well-studied group of inherited disorders, the lysosomal storage diseases. Although many glycosphingolipid catabolic defects have been defined, only one proven inherited disease arising from a defect in ganglioside biosynthesis is known. This disease, because of defects in the first step of ganglioside biosynthesis (GM3 synthase), results in a severe epileptic disorder found at high frequency amongst the Old Order Amish. Here we investigated an unusual neurodegenerative phenotype, most commonly classified as a complex form of hereditary spastic paraplegia, present in families from Kuwait, Italy and the Old Order Amish. Our genetic studies identified mutations in B4GALNT1 (GM2 synthase), encoding the enzyme that catalyzes the second step in complex ganglioside biosynthesis, as the cause of this neurodegenerative phenotype. Biochemical profiling of glycosphingolipid biosynthesis confirmed a lack of GM2 in affected subjects in association with a predictable increase in levels of its precursor, GM3, a finding that will greatly facilitate diagnosis of this condition. With the description of two neurological human diseases involving defects in two sequentially acting enzymes in ganglioside biosynthesis, there is the real possibility that a previously unidentified family of ganglioside deficiency diseases exist. The study of patients and animal models of these disorders will pave the way for a greater understanding of the role gangliosides play in neuronal structure and function and provide insights into the development of effective treatment therapies.

Dietary nitrate is growing in popularity as a sports nutrition supplement. This article reviews the evidence base for the potential of inorganic nitrate to enhance sports and exercise performance. Inorganic nitrate is present in numerous foodstuffs and is abundant in green leafy vegetables and beetroot. Following ingestion, nitrate is converted in the body to nitrite and stored and circulated in the blood. In conditions of low oxygen availability, nitrite can be converted into nitric oxide, which is known to play a number of important roles in vascular and metabolic control. Dietary nitrate supplementation increases plasma nitrite concentration and reduces resting blood pressure. Intriguingly, nitrate supplementation also reduces the oxygen cost of submaximal exercise and can, in some circumstances, enhance exercise tolerance and performance. The mechanisms that may be responsible for these effects are reviewed and practical guidelines for safe and efficacious dietary nitrate supplementation are provided. © The Author(s) 2014.

Hyphal growth of filamentous fungi requires microtubule-based long-distance motility of early endosomes. Since the discovery of this process in Ustilago maydis, our understanding of its molecular basis and biological function has greatly advanced. Studies in U. maydis and Aspergillus nidulans reveal a complex interplay of the motor proteins kinesin-3 and dynein, which co-operate to support bi-directional motion of early endosomes. Genetic screening has shed light on the molecular mechanisms underpinning motor regulation, revealing Hook protein as general motor adapters on early endosomes. Recently, fascinating insight into unexpected roles for endosome motility has emerged. This includes septin filament formation and cellular distribution of the machinery for protein translation. © 2014.

Nature Climate Change | Year: 2014

Changes in climate variability are arguably more important for society and ecosystems than changes in mean climate, especially if they translate into altered extremes1-3. There is a common perception and growing concern that human-induced climate change will lead to more volatile and extremeweather4. Certain types of extreme weather have increased in frequency and/or severity5-7, in part because of a shift in mean climate but also because of changing variability1-3,8-10. In spite of mean climate warming, an ostensibly large number of high-impact cold extremes have occurred in the Northern Hemisphere mid-latitudes over the past decade 11. One explanation is that Arctic amplification-the greater warming of the Arctic compared with lower latitudes12 associated with diminishing sea ice and snow cover-is altering the polar jet stream and increasing temperature variability13-16. This study shows, however, that subseasonal cold-season temperature variability has significantly decreased over the mid- to high-latitude Northern Hemisphere in recent decades. This is partly because northerly winds and associated cold days are warming more rapidly than southerly winds and warm days, and so Arctic amplification acts to reduce subseasonal temperature variance. Previous hypotheses linking Arctic amplification to increased weather extremes invoke dynamical changes in atmospheric circulation11,13-16, which are hard to detect in present observations17,18 and highly uncertain in the future19,20. In contrast, decreases in subseasonal cold-season temperature variability, in accordance with the mechanism proposed here, are detectable in the observational record and are highly robust in twenty-first-century climate model simulations. © 2014 Macmillan Publishers Limited.

SWEEP brings together a unique blend of academics, businesses and policymakers to place natural capital - those elements of nature producing value for people - at the heart of regional decision-making and business processes in the South West (SW). Focussing on the Heart of the South West and Cornwall and Isles of Scilly Local Enterprise Partnership (LEP) regions, SWEEP will radically transform the extent to which NERC science drives sustainable economic growth, improves policy, decision-making and resilience, delivers value for money and enhances health and wellbeing. The UK Government has placed sustainable use of natural capital at the centre of its 25 Year Environment Plan (25YEP). With 800km of spectacular coastline and over a quarter of land within National Parks/Areas of Outstanding Natural Beauty, the SW is rich in natural capital. It is particularly reliant on these natural assets and the ecosystem services deriving from them to power economic growth, attracting more domestic tourists and with higher employment in direct natural capital usage (e.g. agriculture, fisheries) than any other UK region. However, there is also more potential for natural capital-led economic growth; productivity is low, with Gross Value Added 20% below national average and the lowest mean incomes nationally. Heavy reliance on natural capital also brings economic vulnerability and challenges from increasing occurrences of storms, flooding, degradation and pollution that damage that capital and limit economic growth. SWEEP and its business and policy partners have co-designed a work programme utilising NERC-funded research to develop an integrated, cross-sectoral, whole system approach to natural capital-led growth. The regions natural assets are inextricably linked, so traditional decision-making focussing on one sector at a time can result in unintended negative consequences for others. For example agricultural subsidies can lead to. contaminants from land bordering rivers lowering downstream water quality, affecting aquaculture, fisheries, tourism and health. SWEEP will address these problems, realising the benefits of integrated, whole system decision making through five interwoven Impact Themes, aiming to: 1) co-build tools to help business and government understand both the economic and environmental consequences of decisions; and 2) co-develop new business opportunities and natural capital markets giving both private and public sector organisations the means and incentive to improve natures services, reducing their costs and risk exposure and improving their benefits. With partners we have developed an initial set of Impact Cases, each addressing one or more Impact Themes, which will commence at the outset for rapid delivery of impact. They include development of new tools for natural hazard prediction and evaluation of economic/social benefits of enhancing natural capital. Careful integration across these Cases will demonstrate how the SWs high dependence on its natural environment can provide unprecedented opportunities to deliver transformative economic benefits. The SWEEP consortium brings together a uniquely strong mix of environmental scientists, economists, social and health scientists. A team of Impact Fellows will be embedded with partners to deliver the Impact Cases and scope new SWEEP activities. Partners will be integral to design, management and delivery, ensuring that all activities are aligned with user needs and fully integrated, maximising return on NERCs investment. Further value comes from alignment with the new Pioneers, which will be exemplars for the Governments 25YEP. Of only five Pioneers nationally, two will be in the SW, providing the only integrated terrestrial-marine testbed for the 25 YEP. By working with the business and policy institutions involved in the Pioneers, SWEEP will act as a national flagship for environment-led regional growth.
