Chicago is at a tipping point: despite economic strengths, it faces considerable challenges to compete in the “Premier League” of world-class cities, warns the OECD’s review of the Chicago Tri-State Metropolitan Region.

Secretary-General Angel Gurría addresses the Lord Mayor of Copenhagen and others to discuss highlights of the forthcoming OECD report on local green growth, as part of our efforts to develop more effective tools for measuring cities’ progress and monitoring the impact of green policies.

Chile's OECD membership presents challenges both in the context of changing patterns of production and consumption, and in the framework of a more sustainable economy. Specifically, green growth emphasizes improving growth rates, particularly through greening existing industries, as well as through new eco-businesses.

This report presents, for the first time a local ‘green growth’ indicator framework. This indicator framework was developed from the OECD ‘green growth’ strategy at the national level, but modified to highlight issues of transition that are most relevant for local areas.

This LEED project aims to to define key indicators of area-based transition to a low-carbon economy. The objective is to define measurable indicators at regional/local level that can inform over time of transition to low-carbon economic and industrial activities.

The last decade has seen considerable policy attention to the social economy and its contribution to employment, in particular as regards the inclusion and empowerment of vulnerable workers and the provision of appropriate working conditions.

With Africa’s population set to double by 2050, modernising local economies will be vital to make the continent more competitive and to increase people’s living standards, according to the African Economic Outlook 2015, released at the African Development Bank Group’s 50th Annual Meetings.

How Africa urbanises will be critical to the continent’s future growth and development, says the African Economic Outlook 2016 released today at the African Development Bank Group’s 51st Annual Meetings.

This OECD monograph demonstrates how a chemical hazard assessment that considers and ranks all available relevant information - a so-called weight of evidence approach - can be constructed to conclude on a particular hazard endpoint for a chemical, in this case, skin sensitisation for 4-isopropylaniline.

In the past three years, Dirac half-metals (DHMs) have attracted considerable attention and become a high-profile topic in spintronics becuase of their excellent physical properties such as 100% spin polarization and massless Dirac fermions. Two-dimensional DHMs proposed recently have not yet been experimentally synthesized and thus remain theoretical. As a result, their characteristics cannot be experimentally confirmed. In addition, many theoretically predicted Dirac materials have only a single cone, resulting in a nonlinear electromagnetic response with insufficient intensity and inadequate transport carrier efficiency near the Fermi level. Therefore, after several attempts, we have focused on a novel class of DHMs with multiple Dirac crossings to address the above limitations. In particular, we direct our attention to three-dimensional bulk materials. In this study, the discovery via first principles of an experimentally synthesized DHM LaNiO3 with many Dirac cones and complete spin polarization near the Fermi level is reported. It is also shown that the crystal structures of these materials are strongly correlated with their physical properties. The results indicate that many rhombohedral materials with the general formula LnNiO3 (Ln = La, Ce, Nd, Pm, Gd, Tb, Dy, Ho, Er, Lu) in the space group R3c are potential DHMs with multiple Dirac cones.

Two commonly encountered bottlenecks in the structure determination of a protein by X-ray crystallography are screening for conditions that give high-quality crystals and, in the case of novel structures, finding derivatization conditions for experimental phasing. In this study, the phasing molecule 5-amino-2,4,6-triiodoisophthalic acid (I3C) was added to a random microseed matrix screen to generate high-quality crystals derivatized with I3C in a single optimization experiment. I3C, often referred to as the magic triangle, contains an aromatic ring scaffold with three bound I atoms. This approach was applied to efficiently phase the structures of hen egg-white lysozyme and the N-terminal domain of the Orf11 protein from Staphylococcus phage P68 (Orf11 NTD) using SAD phasing. The structure of Orf11 NTD suggests that it may play a role as a virion-associated lysin or endolysin.

A putative open reading frame encoding GTP cyclohydrolase I from Listeria monocytogenes was expressed in a recombinant Escherichia coli strain. The recombinant protein was purified and was confirmed to convert GTP to dihydroneopterin triphosphate (Km = 53 µM; vmax = 180 nmol mg−1 min−1). The protein was crystallized from 1.3 M sodium citrate pH 7.3 and the crystal structure was solved at a resolution of 2.4 Å (Rfree = 0.226) by molecular replacement using human GTP cyclohydrolase I as a template. The protein is a D5-symmetric decamer with ten topologically equivalent active sites. Screening a small library of about 9000 compounds afforded several inhibitors with IC50 values in the low-micromolar range. Several inhibitors had significant selectivity with regard to human GTP cyclohydrolase I. Hence, GTP cyclohydrolase I may be a potential target for novel drugs directed at microbial infections, including listeriosis, a rare disease with high mortality.

A measure that would allow an 80,000-seat NFL-caliber stadium to be built in Inglewood could be on that city’s ballot by this summer after developers submitted almost three times as many signatures than needed for a voter initiative.

“22,216 signatures were submitted to the city clerk today,” said Gerard McCallum, project manager with the Hollywood Park Land Company. “It was unbelievable. The response was more than we could have ever anticipated.”

Normally, before construction can begin on any project there has to be an environmental review, but that can take a long time and time is something in short supply for St. Louis Rams Owner Stan Kroenke and his plan to move the team to L.A.

“We would be going through another three year project process, and the current construction wouldn’t allow that,” said McCallum, referring to the redevelopment of 238 acres of the old Hollywood Park site that was permitted in 2009.

“If we were going to make any modifications, it would have to be approved this year,” said McCallum.

To speed things up, developers decided to bring the stadium project directly to Inglewood voters, which required 8,000 signatures.

Once the signatures are verified, Inglewood’s City Council will consider the measure, then developers hope a special election would take place before the start of the next NFL season.

McCallum says construction would begin whether the Rams or any other team decides to move here, though on Monday Kroenke made another move suggesting a return of the NFL to Los Angeles could be closer than it has been at any point during the last two decades, though not until after the 2015 season. From The St Louis Post-Dispatch:

Rams management sent a letter to regional officials on Monday afternoon. The letter said the team was converting its 30-year lease to an “annual tenancy,” effective April 1 and, “in the absence of intervening events,” extending through March 31, 2016.

The notice, which has long been expected, does two things:

• It allows owner Stan Kroenke to pull the team out of St. Louis as soon as 2016, because the Rams lease will now expire at the end of every season. The original lease was to expire in 2025.
• It also legally binds the Rams to play at the Edward Jones Dome next fall — a point on which many here were uncertain.

Crane fly larvae cause considerable damage to agricultural crops and young trees throughout Europe. New research has demonstrated that certain strains of fungi have significant potential to control crane fly infestations, thus reducing the use of chemical insecticides and enabling more environmentally-friendly strategies for pest control.

Upland peat soils provide a substantial carbon sink if managed properly, according to new research. A study of a peatland area in the UK indicated that it could potentially store approximately 160,000 tonnes of CO2 per year.

Biomass is increasingly used to make biofuels and generate electricity and is seen as a valuable source of renewable energy. A recent study has assessed the key factors relating to the sustainability of bioenergy production and suggests global biomass could potentially meet up to one third of the projected global energy demand in 2050.

The risk of contamination of ground and surface waters and leakage of methane emissions remain key concerns associated with shale gas projects, according to a recent assessment. This is particularly the case if monitoring and regulatory systems are not rigorously enforced. In addition, investment in shale gas could divert resources needed to develop a low-carbon economy, suggest the report’s authors.

A recent study has highlighted the potential of one form of solar power, Concentrating Solar Power (CSP), to make a significant contribution to meeting future electricity demands from renewable sources in Europe.

Denmark aims to develop an energy system based only on renewable energy sources by 2050. Energy saving buildings are an essential part of this plan, according to new research, which investigates how excess heat production from net zero energy buildings (NZEBs) can benefit district heating systems and reduce reliance on combustible fuels.

There is a large potential to improve the global efficiency of energy, land and phosphorus use, finds new research which modelled the effects of four worldwide scenarios between 2010 and 2050. An ‘ambitious resource strategy’ could moderate the increases in energy use (+25% globally instead of +80% in the baseline scenario), phosphorus use (+9% instead of +40%) and arable land (-9% globally, instead of + 4%).

Since the industrial revolution, the ocean has absorbed increased levels of carbon dioxide, leading to the ocean’s pH becoming more acidic. Effects of these pH changes on marine and estuarine biota is the focus of much research effort worldwide and the authors of this study focus on the larval habitat-choice process of a commercially important tropical marine fish species, Lates calcarifer, barramundi.

New research has identified major drivers of food waste around the world. For example, in developing countries a lack of refrigeration technology is a major driver of food waste, and in the developed world low prices and increased choice encourage wasteful behaviour from consumers. Experts predict that drivers such as these will continue to increase food waste.

Europe produces around 450 million tonnes of construction and demolition waste every year, representing a quarter of all waste materials. A recent study of construction and demolition waste suggests that, with the right policies in place, there are good opportunities to ensure sustainable practices through re-use and recycling.

Over a third of all food waste in Sweden is avoidable, according to new research. If such waste minimisation were achieved, there would be less potential for biogas production, but the researchers suggest that this does not represent a compromise because it is currently performed on only a very small amount of waste food.

A new method of processing food waste into fertiliser has been outlined in a recent study. The process uses a digester system with microorganisms to break down organic waste into fertiliser. The resultant fertiliser was used in a low-energy greenhouse to produce a range of food crops. The method is a potential way to utilise food waste and reduce the energy consumption of food production as part of a circular economy.

Between 13% and 16% of waste electric and electronic equipment (WEEE), furniture and leisure goods disposed of at household waste collection centres are in excellent working condition and could be easily be prepared for re-use, finds a new study from Bavaria, Germany. Improvements to waste collection, storage and treatment practices to prevent damage to disposed items could free up a further 13%-29% of these waste streams for re-use. Notably, weatherproof storage for WEEE at collection points could have prevented up to 86% of the damage endured by the studied items.

The EU-27 have committed to a strategic goal of developing an innovative economy based on biotechnology and renewable resources — a so-called ‘bioeconomy’. To achieve this, however, the EU must successfully mobilise resources such as residual biomass — or waste products from organic matter resources. A new study1 has quantified the potential of key residual biomass streams in the EU-27. The results show that residual biomass has a theoretical energy potential equivalent to the annual energy consumption of Italy and Belgium combined, with straw and forestry residues comprising the two most productive potential sources. The findings also reveal specific opportunities for regions including Paris (France) and Jaen (south-central Spain).

Researchers have shown that graphene paper can be used to construct flexible and rechargeable batteries, which may even perform better than non-flexible batteries. These might be used in a range of portable, bendable and rollable devices and could also help develop new energy generation technology, such as flexible solar cells.

Aeration technologies designed to help landfill waste break down faster need to be refined in order to reduce pollution, greenhouse gas emissions and the long-term costs associated with landfill. This is according to a recent review of landfill aeration, which outlines some of the different systems currently available and highlights the need for better monitoring and sharing of data.

Compared with traditional remediation techniques used to remediate brownfield sites, supporters of phytoremediation argue that it is cheaper and more environmentally-friendly. A new analysis has reviewed its strengths, weaknesses, opportunities and threats, and suggests it is well suited to cleaning up sites with low to medium levels of contamination.

A new review examines the potential uses and scientific, technical and manufacturing problems facing ‘van der Waals heterostructures’ - an emerging science which uses building block-like nanomaterials. Van der Waals heterostructures are nanomaterials built by layering different materials, each one atom thick, on top of each other, to create materials with unique properties and uses.

A new study has found evidence for lung toxicity of different forms of ‘cellulose nanocrystals’ (CNCs) in mice. The study suggests that physical characteristics, such as length, of the CNC relates to the type of effect it has on the lung. These nanosized crystals, made from plant-derived materials, are increasingly being used in novel applications, such as cleaning up oil spills in water and flexible electronic displays, and consumer products, which raises concerns about their potential health impacts.

A new study has developed a system to assess the potential of ecosystems to supply ecosystem services in the EU-25 plus Switzerland and Norway. It is one of the first to use historical and projected data on land use change at a continental scale to estimate the provision of ecosystem services and to assess possible trade-offs between them.
