The heat is on: climate change, extreme heat and bushfires in WA

Climate change is increasing the intensity and frequency of heatwaves in Western Australia and driving up the likelihood of very high fire danger weather. Western Australia is experiencing a long-term increase in average temperatures and in 2014 the state recorded its highest ever annual average maximum temperature. The number of heatwave days in Perth has increased by 50% since 1950. Nine of Western Australia’s hottest Januarys on record have occurred in the last 10 years. The number of days per year with severe fire danger weather is projected to almost double in south west Western Australia by 2090 if global carbon emissions are not drastically reduced. Recent fires in Western Australia have been influenced by record hot dry conditions. The long-term trend to hotter weather in Western Australia has worsened fire weather and contributed to an increase in the frequency and severity of bushfires. The concept of a normal bushfire season is rapidly changing as bushfires increase in number, burn for longer and affect larger areas of land. By 2030, the number of professional firefighters in WA will need to more than double to meet the increasing risk of bushfires. 3. The economic, social and environmental costs of increased extreme heat and bushfire activity is likely to be immense. In Perth, from 1994-2006, there were over 20 heat attributable deaths per year. If average maximum temperatures were 2°C warmer, this number would almost double to 40 deaths. Some of Western Australia’s most fire-prone regions may become unlivable as the risks to lives and property caused by bushfires continue to increase. Without effective action on climate change, there will be 20 times the number of dangerous days for outdoor workers by 2070, reducing productivity. 4. Tackling climate change is critical to protecting Western Australia’s prosperity. As a nation we must join the global effort to substantially reduce emissions and rapidly move away from fossil fuels to renewable energy if we are to limit the severity of extreme heat and bushfires both in Western Australia and nationally

Soft Robotics: A Route to Equality, Diversity, and Inclusivity in Robotics

: Robotics is entering our daily lives. The discipline is increasingly crucial in fields such as agriculture, medicine, and rescue operations, impacting our food, health, and planet. At the same time, it is becoming evident that robotic research must embrace and reflect the diversity of human society to address these broad challenges effectively. In recent years, gender inclusivity has received increasing attention, but it still remains a distant goal. In addition, awareness is rising around other dimensions of diversity, including nationality, religion, and politics. Unfortunately, despite the efforts, empirical evidence shows that the field has still a long way to go before achieving a sufficient level of equality, diversity, and inclusion across these spectra. This study focuses on the soft robotics community-a growing and relatively recent subfield-and it outlines the present state of equality and diversity panorama in this discipline. The article argues that its high interdisciplinary and accessibility make it a particularly welcoming branch of robotics. We discuss the elements that make this subdiscipline an example for the broader robotic field. At the same time, we recognize that the field should still improve in several ways and become more inclusive and diverse. We propose concrete actions that we believe will contribute to achieving this goal, and provide metrics to monitor its evolution

Madin-Darby bovine kidney (MDBK) cells are a suitable cell line for the propagation and study of the bovine poxvirus lumpy skin disease virus

Lumpy skin disease virus (LSDV) is a poxvirus that causes systemic disease in cattle, resulting in substantial economic loss to affected communities. LSDV is a rapidly emerging pathogen of growing global concern that recently spread from Africa and the Middle East into Europe and Asia, impacting the cattle population in these regions. An increase in research efforts into LSDV is required to address key knowledge gaps, however this is hampered by lack of suitable cell lines on which to propagate and study the virus. In this work we describe the replication and spread of LSDV on Madin-Darby bovine kidney (MDBK) cells, and the formation of foci-type poxvirus plaques by LSDV on MDBK cells. Methods utilising MDBK cells to quantify neutralising antibodies to LSDV, and to purify LSDV genomic DNA suitable for short read sequencing are described. These research methods broaden the tools available for LSDV researchers and will facilitate the gathering of evidence to underpin the development of LSD control and prevention programmes

Impact of COVID-19 on cardiovascular testing in the United States versus the rest of the world

Objectives: This study sought to quantify and compare the decline in volumes of cardiovascular procedures between the United States and non-US institutions during the early phase of the coronavirus disease-2019 (COVID-19) pandemic. Background: The COVID-19 pandemic has disrupted the care of many non-COVID-19 illnesses. Reductions in diagnostic cardiovascular testing around the world have led to concerns over the implications of reduced testing for cardiovascular disease (CVD) morbidity and mortality. Methods: Data were submitted to the INCAPS-COVID (International Atomic Energy Agency Non-Invasive Cardiology Protocols Study of COVID-19), a multinational registry comprising 909 institutions in 108 countries (including 155 facilities in 40 U.S. states), assessing the impact of the COVID-19 pandemic on volumes of diagnostic cardiovascular procedures. Data were obtained for April 2020 and compared with volumes of baseline procedures from March 2019. We compared laboratory characteristics, practices, and procedure volumes between U.S. and non-U.S. facilities and between U.S. geographic regions and identified factors associated with volume reduction in the United States. Results: Reductions in the volumes of procedures in the United States were similar to those in non-U.S. facilities (68% vs. 63%, respectively; p = 0.237), although U.S. facilities reported greater reductions in invasive coronary angiography (69% vs. 53%, respectively; p < 0.001). Significantly more U.S. facilities reported increased use of telehealth and patient screening measures than non-U.S. facilities, such as temperature checks, symptom screenings, and COVID-19 testing. Reductions in volumes of procedures differed between U.S. regions, with larger declines observed in the Northeast (76%) and Midwest (74%) than in the South (62%) and West (44%). Prevalence of COVID-19, staff redeployments, outpatient centers, and urban centers were associated with greater reductions in volume in U.S. facilities in a multivariable analysis. Conclusions: We observed marked reductions in U.S. cardiovascular testing in the early phase of the pandemic and significant variability between U.S. regions. The association between reductions of volumes and COVID-19 prevalence in the United States highlighted the need for proactive efforts to maintain access to cardiovascular testing in areas most affected by outbreaks of COVID-19 infection

Finishing the euchromatic sequence of the human genome

The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead

La segmentation (typologisation) des perceptions et des attitudes des visiteurs comme outil d'information pour la gestion et les stratégies de communication ciblées dans les zones côtières et marines protégées

International audienceCommunication is a strategic management lever for promoting user knowledge, understanding, acceptance, support, and conservation-related pro-environmental behavior within Coastal and Marine Protected Areas (CMPAs). But while user segmentation is considered a traditional operational tool for targeting user audiences effectively within terrestrial protected areas, research also highlights a low level of concrete application to CMPAs. Based on Public Perceptions Research literature, this study explores a panel of eight theoretical variables that reflect the multidimensional character of recreationists’ perceptions of CMPAs and how the related results could inform appropriate CMPA communication strategies. Onsite face-to-face interviews with 1,000 users were conducted for seven recreational activities (hiking, surfing, scuba-diving, boating, sailing, kite-surfing, kayaking) across a total of ten local sites. Results revealed that despite sharing a common motivation for being in contact with nature, recreationists expressed diverse perceptions and attitudes toward CMPAs and management, which can be divided into five segments: “CMPA-Not-convinced” (31.3% of all recreationists), “CMPA-Local Conservator” (11.5%), “CMPA-Not-Responsible” (12.7%), “CMPA-Passers-by” (20.1%) and “CMPA-Convinced” (24.4%). Findings show the value of visitor segmentation as an operational tool to inform CMPA management and communication strategies in a context of low knowledge about visitor audiences
