Abstract: We report the discovery of a new 5.78 ms period millisecond pulsar (MSP), PSR J1740−5340B (NGC 6397B), in an eclipsing binary system discovered with the Parkes radio telescope (now also known as Murriyang) in Australia and confirmed with the MeerKAT radio telescope in South Africa. The measured orbital period, 1.97 days, is the longest among all eclipsing binaries in globular clusters (GCs) and consistent with that of the coincident X-ray source U18, previously suggested to be a “hidden MSP.” Our XMM-Newton observations during NGC 6397B’s radio-quiescent epochs detected no X-ray flares. NGC 6397B is either a transitional MSP or an eclipsing binary in its initial stage of mass transfer after the companion star left the main sequence. The discovery of NGC 6397B potentially reveals a subgroup of extremely faint and heavily obscured binary pulsars, thus providing a plausible explanation for the apparent dearth of binary neutron stars in core-collapsed GCs as well as a critical constraint on the evolution of GCs.

Abstract: This article focuses on the Pacific experiences of the German ornithologist and ethnologist Otto Finsch (1839?1917). Between 1879 and 1882, Finsch voyaged extensively in the Pacific, visiting Hawai?i, parts of Micronesia and island Melanesia, New Zealand, New Guinea and the Torres Strait Islands. In 1884, he returned to New Guinea and was instrumental in the acquisition of Kaiser-Wilhelmsland and the Bismarck Archipelago as German protectorates.While his numerous publications on the indigenous inhabitants of these areas naturally reflect the prevailing scientific and colonial discourses of the late nineteenth century, I argue that they were also significantly shaped by his personal encounters with Pacific peoples. Through close comparisons of texts produced before, during and after his Pacific voyages, I discuss the ways in which these encounters challenged Finsch's pre-voyage assumptions about ?race' and human difference: the breadth of in idual variation within supposedly homogeneous races, the extent of overlap between such races, and the reliability of particular cultural practices as diagnostics of savagery or civilization. I also emphasize links between Finsch's story and broader issues in the history of science, including the influence of observers' trajectories of travel on the constitution of regional topographies of difference, the standardization and mobilization of travellers' observations for metropolitan audiences, the human interface between discovery and communication, and the policing of scientific knowledge and interpretation of field observations by metropolitan authorities.

Abstract: В 1859 г. прибалтийский немец, анатом и эмбриолог Карл Эрнст фон Бэр с энтузиазмом писал, что Императорская академия наук в Санкт-Петербурге недавно пополнила свои краниологические коллекции в общей сложности «83 череп[ами] разных народов», подаренными немцем Георгом Йозефом Пейчем, военным врачом, служившим в голландских вооруженных силах в Батавии (ныне Джакарта). Один этот случай демонстрирует, насколько физическая антропология в России XIX в. была переплетена с научной и колониальной деятельностью других европейских народов. В нашей статье предлагается обзор контактов России с народами Тихого океана в XIX в., поскольку одним из аспектов этих контактов было приобретение человеческих останков для российских коллекций, что позволяет исследовать транснациональные сети научных связей и обмена. Мы начнем с торговой, дипломатической и научной деятельности русских экспедиций в Тихом океане, затем рассмотрим профессионализацию краниологии и расширение Анатомического музея Академии наук в Санкт-Петербурге при Карле Эрнсте фон Бэре и закончим описанием формирования в Москве второго центра антропологических исследований в России.

Abstract: This article is a historiography, or critical review of the history, of Australian archaeology. It commences with a discussion of the two major regional histories of Australian archaeology, and a survey of the literature on the removal and scientific use of human remains. This is followed by an examination of the two major approaches to the history of Australian archaeology—in idual and collective biography, and the use of specific archaeological sites or broader geographical regions—then three complementary but less used historical approaches. Finally, I offer suggestions for further research in the history of Australian archaeology.

Abstract: Warning Readers of this article are warned that it may contain terms, descriptions and opinions that are culturally sensitive and/or offensive to Aboriginal and Torres Strait Islanders. Silesian traveller-naturalist Lothar Becker’s two visits to Victoria in 1849–52 and 1855–65 brought him into contact with Aboriginal people living in Western Victoria, Melbourne, the Murray River at Albury, and Gippsland. His travels took him to areas now recognised as the traditional lands of the Gunaikurnai, Wathaurung, Wiradjuri and Wurundjeri peoples. Becker’s publications include scattered observations on Aboriginal appearance, lifeways, diet, skills, and beliefs. Although these observations were limited by his inability to speak any Aboriginal languages and coloured by his assumptions about the inferiority of Aboriginal culture, they nevertheless document small but significant fragments of what has recently been termed ‘Aboriginal Biocultural Knowledge’.

Abstract: Noroviruses are the dominant cause of outbreaks of gastroenteritis worldwide, and interactions with human histo-blood group antigens (HBGAs) are thought to play a critical role in their entry mechanism. Structures of noroviruses from genogroups GI and GII in complex with HBGAs, however, reveal different modes of interaction. To gain insight into norovirus recognition of HBGAs, we determined crystal structures of norovirus protruding domains from two rarely detected GII genotypes, GII.10 and GII.12, alone and in complex with a panel of HBGAs, and analyzed structure-function implications related to conservation of the HBGA binding pocket. The GII.10- and GII.12-apo structures as well as the previously solved GII.4-apo structure resembled each other more closely than the GI.1-derived structure, and all three GII structures showed similar modes of HBGA recognition. The primary GII norovirus-HBGA interaction involved six hydrogen bonds between a terminal αfucose1-2 of the HBGAs and a dimeric capsid interface, which was composed of elements from two protruding subdomains. Norovirus interactions with other saccharide units of the HBGAs were variable and involved fewer hydrogen bonds. Sequence analysis revealed a site of GII norovirus sequence conservation to reside under the critical αfucose1-2 and to be one of the few patches of conserved residues on the outer virion-capsid surface. The site was smaller than that involved in full HBGA recognition, a consequence of variable recognition of peripheral saccharides. Despite this evasion tactic, the HBGA site of viral vulnerability may provide a viable target for small molecule- and antibody-mediated neutralization of GII norovirus.

Abstract: Salinity in Victoria's irrigated districts can be understood as the result not only of environmental predisposition and technological inadequacies, but of a prevailing political philosophy which considered irrigation as a social and economic good per se. Victorian authorities (governments and water institutions), anxious to secure the state's economic prosperity and to encourage the establishment of independent family smallholdings, tended to underestimate the actual and potential severity of salinity problems, and to blame their development on the farming practices of in idual landholders rather than on systemic failure. Their dismissal of farmers' concerns as 'ignorance' and their tardiness in implementing remedial measures in salt-affected areas were indicative not only of the restrictions imposed by insufficient knowledge, primitive technologies, and limited finances, but also of official resistance to the challenging of 'progress-through-irrigation' narratives. The salinity problems experienced today in many of Victoria's irrigated districts therefore reflect the long-term consequences of a broadly progress-oriented philosophy of natural resource management.
