Zap! : Nikola Tesla takes charge
Growing up in Smiljan, Croatia, Nikola Tesla dreamed about harnessing the power of Niagara Falls. In 1884, he walked down the gangplank into the New York Harbor with four cents in his pocket, a book of poems, a drawing of a flying machine, and a letter of introduction to Thomas Edison, the \"electrical wizard\" of America. Upon meeting, Edison sent Tesla to fix the \"SS Oregon\" as a test and was so astounded that he offered Tesla a job at his factory. Tesla and Edison had different views about electricity; Tesla wanted to develop an \"alternate\" current while Edison wanted to stick to the \"direct\" current system. Edison offered Tesla a large sum to make his direct current system more efficient, but when the work was done, Edison refused to pay. Tesla quit and when things were looking bleak, he met George Westinghouse, who also thought that alternating current was the way to light up America. He gave Tesla a job and in 1896, Tesla and Westinghouse built a generator at Niagara Falls that was able to send power as far as Buffalo, New York.

Innovation in Coping with the COVID-19 Pandemic: The Best Practices from Five Smart Cities in Indonesia
In relation to innovations which help to cope with the COVID-19 pandemic, the best practices of several smart cities become an important input to organize and create strategies for future cities. This research aims to identify the responses of cities to the COVID-19 pandemic; analyze their innovation in tackling the COVID-19 pandemic; and create strategies and planning for the future of the cities. This study analyzes aspects such as the use of information and communication technology (ICT), smart city implementation, the biological disaster of the COVID-19 pandemic, the environment, and spatial plans. This research was carried out in five smart cities using a case study. The results indicated that each case had innovations for coping with the COVID-19 pandemic. They showed a uniqueness and local innovations adapted to the problems faced in the five case areas. The innovations were demonstrated by the use of ICT-based applications in several public services as part of smart city implementation. The concept of a smart city, which addresses the biological disaster of the COVID-19 pandemic through the existence of ship-based isolation centers and sociotechnical innovations, was then adapted in various cities throughout Indonesia. In terms of the smart environment concept, this is translated through technological and social innovation approaches to improve medical and domestic waste management, public service systems, and the socialization of environmental protection programs in cities during the pandemic. The COVID-19 pandemic is allegedly accelerating the implementation of the smart city concept in spatial planning. There is a tendency for the use of public space in the city center to shift to local-scale service centers. Additionally, other activities are increasingly occupying the digital space so that it affects the arrangement of spatial organization and increases the need for ICT infrastructure. The efficient and flexible use of applications for supporting the implementation of smart cities needs to be broadened for the public services provided by both the government and private sectors. Meanwhile, in relation to the dimensions of a smart environment, it is necessary to take into account the waste management as a result of COVID-19. The same case is the aspect of spatial planning in which it is necessary to redesign open spaces for public use. City planning in the future also needs to be capable of the smart mitigation of non-physical disasters, such as the COVID-19 pandemic.

Distribution and genetic diversity of five invasive pests of Eucalyptus in sub-Saharan Africa
Eucalyptus is one of the most planted tree genera across the world, but is heavily challenged by invasive insect pests originating from the native range of these trees. The rate of introduction of non-native Eucalyptus-feeding insects has increased globally, including in sub-Saharan Africa where Eucalyptus trees have an important socio-economic role. In this study, we mapped the distribution and examined the genetic diversity of non-native Eucalyptus insect pests in 14 countries across sub-Saharan Africa. We focused on five foliage-feeding insect pests of Eucalyptus which are known to be present in the region, namely the bluegum chalcid wasp, Leptocybe invasa; the redgum lerp psyllid, Glycaspis brimblecombei; the bronze bug, Thaumastocoris peregrinus; the Eucalyptus weevil, Gonipterus sp.n.2; and the Eucalyptus gall wasp, Ophelimus maskelli. Insect samples were collected through structured surveys and small-scale sampling which were both combined with published literature to determine the distribution of these insect pests. Genetic diversity of each of these insect pests was estimated/assessed based on mitochondrial cytochrome oxidase I (COI) or cytochrome b (Cyt b) sequence data. Except O. maskelli, which is a relatively recent arrival, the other insect pests were found broadly distributed across the sampled countries, with first reports in many countries. Analysis of genetic diversity confirmed a common origin of geographically distant populations for G. brimblecombei and O. maskelli, moderate diversity for T. peregrinus and Gonipterus sp.n.2 and at least two distinct lineages for L. invasa. Two divergent haplogroups of L. invasa, with overlapping geographic range were confirmed in Ghana, Malawi, Sierra Leone, South Africa and Zimbabwe. Compared to published literature, new haplotypes were detected for T. peregrinus, Gonipterus sp.n.2 and L. invasa, suggesting multiple introduction of those pests in the region. Results of this study will have implications for quarantine, management and future research of Eucalyptus insect pests in the region and beyond.
