    A rich locality in South Kensington: the fossil hominin collection of the Natural History Museum, London

    Get PDF
    The primacy of fossils in the Natural History Museum (NHM) goes back to the very origins of the Museum, but the first fossil hominins in the collections were probably the Upper Palaeolithic remains from Bruniquel, which were accessioned in 1864. This founded a collection which has continued to expand into this century. While there have been many compilations and descriptions of the fossil hominin collection at the NHM over its long history, to our knowledge no‐one has prepared a review of the collection itself. The intention of the current paper is to synthesize earlier sources with accounts of new finds, revised chronologies and rediscovered treasures in order to illustrate the breadth and continuing importance of the fossil hominins curated at the NHM. We list and discuss all the hominin material known or thought to pre‐date the Holocene. These form a collection of great importance, both in terms of their research

    Prehistory of the British Isles: A tale of coming and going

    Get PDF
    It is now recognised that Britain has not always been geographically isolated from Europe and, for most of the last one million years, formed an extension of the northwest European landmass. During most of this time, Britain was accessible to migrating humans and animals, although climatic conditions varied greatly from Mediterranean-like through to glaciations and extreme cold, making Britain a difficult place to settle for any length of time. The oldest evidence for humans in Britain dates to between about 850,000 and 1 million years ago. Recovered lithic artefacts suggest that hominin species occupied and deserted the British Isles at least nine times. This article reviews the prehistory of the British Isles and presents the main sites and time periods

    Sir Arthur Keith's Legacy: Re-discovering a lost collection of human fossils Quaternary International

    Get PDF
    In 2001, a collection of skeletal material was donated to the Natural History Museum, London, by the Royal College of Surgeons, London. It consisted of boxes discovered among the personal belongings of Sir Arthur Keith. This paper describes the work undertaken to identify and document the human skeletal material in the Keith Collection. The study identified the human fossils as having come from a number of excavations directed by Dorothy Garrod in the 1920s and 30s in Israel. The collection contains the long considered lost human skeletal collection from the type-site of the Natufian industry: Shukbah Cave. The majority of this material is of Natufian origin but contains a few Neanderthal specimens. A small amount of heavily fragmented bones associated with Skhul VII and IX were also found. The most remarkable of the re-discovered collection is the material from el-Wad and Kebara Caves. It was identified to be the missing material from the Middle and Upper Paleolithic levels briefly described in 1939 in The Stone Age of Mount Carmel by Theodore McCown and Sir Arthur Keith. These important fossils hold great potential to answer questions about the Middle to Upper Paleolithic transition in the Near East, and the emergence of anatomically modern humans

    Stem cell therapies for ischemic cardiovascular diseases

    Myocardial infarction results in loss of cardiac muscle and deficiency in cardiac performance. Likewise, peripheral artery disease can result in critical limb ischemia leading to reduced mobility, non-healing ulcers, gangrene and amputation. Both of these common conditions diminish quality of life and enhance risk of mortality. Successful advances in treatment have led to more people surviving incidences of myocardial infarction or living with peripheral artery disease. However, the current treatments are inadequate in repairing ischemic tissue. Over the last 5 years, a vast number of patents have been submitted concerning the use of stem cells, which correlates with the exponential growth in stem cell publications. Exploiting stem cell therapy offers a real potential in replacing ischemic tissue with functional cells. In this paper, we review recent patents concerning stem cell therapy that have the potential to provide or potentiate novel treatment for ischemic cardiovascular disease. In addition, we evaluate the promise of the inventions by describing some clinical trials that are currently taking place, as well as considering how current research on ischemic cardiovascular disease may change the patent landscape in the future

    On the Limits of Liberalism in Participatory Environmental Governance: Conflict and Conservation in Ukraine\u27s Danube Delta

    Get PDF
    Participatory management techniques are widely promoted in environmental and protected area governance as a means of preventing and mitigating conflict. The World Bank project that created Ukraine’s Danube Biosphere Reserve included such ‘community participation’ components. The Reserve, however, has been involved in conflicts and scandals in which rumour, denunciation and prayer have played a prominent part. The cases described in this article demonstrate that the way conflict is escalated and mitigated differs according to foundational assumptions about what ‘the political’ is and what counts as ‘politics’. The contrasting forms of politics at work in the Danube Delta help to explain why a 2005 World Bank assessment report could only see failure in the Reserve’s implementation of participatory management, and why liberal participatory management approaches may founder when introduced in settings where relationships are based on non-liberal political ontologies. The author argues that environmental management needs to be rethought in ways that take ontological differences seriously rather than assuming the universality of liberal assumptions about the individual, the political and politics

    The emerging zika virus epidemic in the Americas: Research priorities

    Get PDF
    On February 1, 2016, the World Health Organization declared a “public health emergency of international concern” regarding neurological disorders associated with the rapid emergence of Zika virus (ZIKV) in the Americas. Since being detected in Brazil in early 2015, ZIKV has spread extensively, with most countries in Latin America and the Caribbean now reporting local transmission of the virus. An association between congenital ZIKV infection and birth defects, most prominently microcephaly, has prompted intense concern among health officials and the public

    Comparison of the VIMOS-VLT Deep Survey with the Munich semi-analytical model. II. The colour-density relation up to z=1.5

    [Abridged] We perform on galaxy mock catalogues the same colour-density analysis made by Cucciati et al. (2006) on a 5 Mpc/h scale using the VVDS-Deep survey, and compare the results from mocks with observed data. We use mocks with the same flux limits (I=24) as the VVDS (CMOCKS), built using the semi- analytic model by De Lucia & Blaizot (2007) applied to the Millennium Simulation. From CMOCKS, we extracted samples of galaxies mimicking the VVDS observational strategy (OMOCKS). We computed the B-band Luminosity Function LF and the colour-density relation (CDR) in the mocks. We find that the LF in mocks roughly agrees with the observed LF, but at z<0.8 the faint-end slope of the model LF is steeper than the VVDS one. Computing the LF for early and late type galaxies, we show that mocks have an excess of faint early-type and of bright late-type galaxies with respect to data. We find that the CDR in OMOCKS is in excellent agreement with the one in CMOCKS. At z~0.7, the CDR in mocks agrees with the VVDS one (red galaxies reside mainly in high densities). Yet, the strength of the CDR in mocks does not vary within 0.2<z<1.5, while the observed relation flattens with increasing z and possibly inverts at z=1.3. We argue that the lack of evolution in the CDR in mocks is not due only to inaccurate prescriptions for satellite galaxies, but that also the treatment of central galaxies has to be revised. The reversal of the CDR can be explained by wet mergers between young galaxies, producing a starburst event. This should be seen on group scales. A residual of this is found in observations at z=1.5 on larger scales, but not in the mocks, suggesting that the treatment of physical processes affecting satellites and central galaxies in models should be revised.Comment: 15 pages, 12 figures, accepted for publication in A&
