California’s rapid renewable energy expansion has led to a boom in large-scale solar and wind projects and a huge expansion of rooftop solar. As costs have fallen, solar energy has become much less expensive, and utility-scale solar and wind are now less expensive than new gas plants, and far less expensive than existing coal.

Iceland is moving closer to plugging European homes into the volcanic island nation’s geothermal and hydropower reserves via what would be the world’s longest power cable, according to the country’s largest energy producer.

Clean water — it’s a precious resource in hot demand right now, for more than taking a shower or watering our crops. The United Nations projects the world’s population will grow by another billion people, to 8.4 Billion, by 2030. More people means more need for food, water, electricity, and other necessities. Beyond the obvious demands for water, our increasing appetite for electricity also requires water — and plenty of it. Most of the electricity generated in the U.S. uses water in some capacity.

In late February, Hawaiian Electric Companies announced that they have achieved a consolidated 27 percent renewable portfolio standard in 2018, even with the loss of Hawaii Island’s geothermal resource for most of the year following the Kilauea volcanic eruption.

ABSTRACT

The Escherichia coli microcin C (McC) and related compounds are potent Trojan horse peptide-nucleotide antibiotics. The peptide part facilitates transport into sensitive cells. Inside the cell, the peptide part is degraded by nonspecific peptidases releasing an aspartamide-adenylate containing a phosphoramide bond. This nonhydrolyzable compound inhibits aspartyl-tRNA synthetase. In addition to the efficient export of McC outside the producing cells, special mechanisms have evolved to avoid self-toxicity caused by the degradation of the peptide part inside the producers. Here, we report that histidine-triad (HIT) hydrolases encoded in biosynthetic clusters of some McC homologs or by standalone genes confer resistance to McC-like compounds by hydrolyzing the phosphoramide bond in toxic aspartamide-adenosine, rendering them inactive.

IMPORTANCE Uncovering the mechanisms of resistance is a required step for countering the looming antibiotic resistance crisis. In this communication, we show how universally conserved histidine-triad hydrolases provide resistance to microcin C, a potent inhibitor of bacterial protein synthesis.

Studies of the former NE England coalfield in Tyneside demonstrated that heat flow perturbations in boreholes were due to the entrainment and lateral dispersion of heat from deeper in the subsurface through flooded mine workings. This work assesses the influence of historical mining on geothermal observations across Greater Glasgow. The regional heat flow for Glasgow is 60 mW m^–2 and, after correction for palaeoclimate, is estimated as c. 80 mW m^–2. An example of reduced heat flow above mine workings is observed at Hallside (c. 10 km SE of Glasgow), where the heat flow through a 352 m deep borehole is c. 14 mW m^–2. Similarly, the heat flow across the 199 m deep GGC01 borehole in the Glasgow Geothermal Energy Research Field Site is c. 44 mW m^–2. The differences between these values and the expected regional heat flow suggest a significant component of horizontal heat flow into surrounding flooded mine workings. This deduction also influences the quantification of deeper geothermal resources, as extrapolation of the temperature gradient above mine workings would underestimate the temperature at depth. Future projects should consider the influence of historical mining on heat flow when temperature datasets such as these are used in the design of geothermal developments.

Most British railway embankments were constructed between 120 and 180 years ago without the benefit of modern design and construction methods. This can result in undesirable load-deformation characteristics and consequent disruption to present-day railway operations, for which there is unprecedented demand. Annual rail passenger kilometres have approximately doubled in the last 20 years and freight has increased by 60% over the same period. Whereas elements such as rails or bridges can be refurbished or replaced to meet increasing demand, the same is not usually feasible for embankments. Development of techniques to assess embankment performance risks posed by operational capacity enhancements is therefore of increasing significance to railway geotechnical asset management. The two case studies presented in this paper demonstrate how geospatial analysis and data management techniques may be applied to this challenge at both strategic (regional or national) and tactical (site-specific) scales for embankments incorporating plastic clay fill. The case studies also demonstrate, in a world of ever more abundant data, the growing need for engineering geologists and geotechnical engineers to augment their traditional knowledge with comprehensive data management and geospatial analysis skills, these being essential for modern infrastructure asset management.

Strategic geotechnical asset management considers the whole of an organization's earthworks portfolio and is concerned with setting an overall earthworks asset management policy with long-term objectives related to asset performance, safety and condition, and identifying how those objectives can best be met, now and into the future. A risk-based approach is adopted that requires an understanding of the likelihood that any of the earthworks may fail, combined with a knowledge of the consequences should they fail. Procedures are required to identify those earthworks that are most vulnerable to failure under the influence of triggering events, such as extreme weather. The risks are managed through a mix of interventions to reduce the likelihood of failure and mitigations to reduce the impact of failure. Many of the challenges of implementing a strategic earthworks policy have, or are, being met by the main UK transportation infrastructure organizations.

This case study aims to identify the cubic capacity and geometry of the geological body of silt–organic sediments in the environment of a former gravel pit situated in a drainless depression of the alluvium of the Čierna voda River. It is located in the well-known geotourism locality of Slnečné Jazera in Senec, in the SW of Slovakia. To identify the body, electrical resistivity tomography was combined with the use of sonar. The research shows that this approach is appropriate for a number of activities that are subjects of engineering-geological investigations. The cubic capacity and geometry of specific aqueous engineering-geological environments must be determined in connection with the need for the management, control, quantification and extraction of selected sedimentary bodies. In addition, the management of sustainable development of reservoirs, sedimentation basins, industrial ponds, settling pits and natural pools for recreation (the subject of the case study) is important to control the limit amounts of sediments in such environments. The results of this study may be applied in analogous engineering-geological conditions. The drainless depression Slnečné Jazera contained a body of silt–organic sediments amounting to 23 000 m³ (41 Olympic-size pools of 25 m x 12.5 m x 1.8 m). The maximum thickness of the bottom sediments was about 6.3 m on the alluvium with an articulated morphology owing to the submerged digging of gravel. The proposed approach improved the control of extraction of the sedimentary body and optimized the engineering-geological conditions in this geotourism locality.

Filmmaker Karan Johar says he is bringing up his three-year-old twins Yash and Roohi by giving them emotional encouragement, and is making sure that they dont fall into stereotypes. "All of us are very proud parents, we all love our children. And it's very integral that we give them all the love, the attention and the care. We also really make their home feel beautiful, we make them love their home, we make them feel like home is where the heart is," Karan said.

"But we sometimes miss the point, we sometimes pretend that their home is just their residence, but that's not true. Our planet is also our home. There are few things that I have done with my kids at a very young age apart from the emotional encouragement that one has to always give them about making sure that they don't fall into stereotypes," he added.

The filmmaker continued: "The other thing that I do is I tell them about plastic, single use plastic and about how it's important not to consume single use plastic, because you know that it's a big deterrent to our planet and we must be very careful. So, saying no to plastic is the one thing that I've been actually inculcating within their sensibility."

Now, Karan has joined hands with Neha Dhupia, Soha Ali Khan, Esha Deol, Tusshar Kapoor, Pragya Kapoor, Kunal Khemu, Amrita Arora and Neelam Kothari to take a pledge to protect the planet through a campaign by Simone Khambatta's parenting and motherhood blog Mama Says.

Neha Dhupia said: "Apart from all the other conscious work that we are doing, I also pledge that we continue buying wooden toys for our daughter Mehr, try and keep her away from plastic toys as much as we can. And more importantly we are totally open to hand me downs. Mehr has got a lot of friends who are six months or a year older and we believe in hand me down toys, clothes, books, all of it. It's great on the pocket and more importantly it's very good for the environment," added the actress.

To this, Soha added: "I pledge to use a reusable water bottle with me every time I step out of the house instead of buying plastic bottles because I care about the future of our children and our grandchildren on our planet."

"The pandemic has made us realise many things with the most important one being that we need to care for Mother Earth! We don't have to do big things, we have to do small things but have to do it together," Khambatta said.
