The consequences of degradation of environmental quality as well as the consequences of environmental policies are typically unevenly distributed. In general, poorer countries and lower income households are more severely affected by environmental degradation and at the same time have less capacity to adapt.

Chile has taken steps to address the rising environmental pressures from its rapid economic growth, strengthening its environmental institutions and introducing new instruments, including a carbon tax. It now needs to move ahead and thoroughly implement policy measures to stem the threat to its land, air and water, according to a new OECD report.

New Zealanders enjoy a high environmental quality of life and access to pristine wilderness. However, New Zealand’s growth model, based largely on exploiting natural resources, is starting to show its environmental limits with increasing greenhouse gas emissions and water pollution, according to a new OECD report.

Ireland needs to prepare itself to meet rising pressures on public finances from an ageing population and significant external risks such as new EU-UK trade barriers post Brexit. Another important development could be future changes to the international tax rules, according to a new OECD report.

Pressure can play a key role in probing the structure and dynamics of membrane assemblies, and is also critical to the biology and adaptation of deep-sea organisms. This article presents an overview of the effect of pressure on the structure of membranes and recent developments in high-pressure instrumentation.

Strontium tetra­gallate(II,III) tetra­arsenide, SrGa4As4, was synthesized in a Walker-type multianvil apparatus under high-pressure/high-temperature conditions of 8 GPa and 1573 K. The com­pound crystallizes in a new structure type (P3221, Z = 3) as a three-dimensional (3D) framework of corner-sharing SrAs8 quadratic anti­prisms with strontium situated on a twofold rotation axis (Wyckoff position 3b). This arrangement is surrounded by a 3D framework which can be described as alternately stacked layers of either condensed GaIIIAs4 tetra­hedra or honeycomb-like layers built up from distorted ethane-like GaII2As6 units com­prising Ga—Ga bonds.

Advances in both non-resonant and resonant X-ray magnetic diffraction since the 1980s have provided researchers with a powerful tool for exploring the spin, orbital and ion degrees of freedom in magnetic solids, as well as parsing their interplay. Here, we discuss key issues for performing X-ray magnetic diffraction on single-crystal samples under high pressure (above 40 GPa) and at cryogenic temperatures (4 K). We present case studies of both non-resonant and resonant X-ray magnetic diffraction under pressure for a spin-flip transition in an incommensurate spin-density-wave material and a continuous quantum phase transition of a commensurate all-in–all-out antiferromagnet. Both cases use diamond-anvil-cell technologies at third-generation synchrotron radiation sources. In addition to the exploration of the athermal emergence and evolution of antiferromagnetism discussed here, these techniques can be applied to the study of the pressure evolution of weak charge order such as charge-density waves, antiferro-type orbital order, the charge anisotropic tensor susceptibility and charge superlattices associated with either primary spin order or softened phonons.

Single crystals of the high-pressure phases II and III of pyridine have been obtained by in situ crystallization at 1.09 and 1.69 GPa, revealing the crystal structure of phase III for the first time using X-ray diffraction. Phase II crystallizes in P212121 with Z' = 1 and phase III in P41212 with Z' = ½. Neutron powder diffraction experiments using pyridine-d5 establish approximate equations of state of both phases. The space group and unit-cell dimensions of phase III are similar to the structures of other simple compounds with C2v molecular symmetry, and the phase becomes stable at high pressure because it is topologically close-packed, resulting in a lower molar volume than the topologically body-centred cubic phase II. Phases II and III have been observed previously by Raman spectroscopy, but have been mis-identified or inconsistently named. Raman spectra collected on the same samples as used in the X-ray experiments establish the vibrational characteristics of both phases unambiguously. The pyridine molecules interact in both phases through CH⋯π and CH⋯N interactions. The nature of individual contacts is preserved through the phase transition between phases III and II, which occurs on decompression. A combination of rigid-body symmetry mode analysis and density functional theory calculations enables the soft vibrational lattice mode which governs the transformation to be identified.

X-ray diffraction studies of crystals under pressure and quantitative experimental charge density analysis are among the most demanding types of crystallographic research. A successful feasibility study of the electron density in the mineral grossular under 1 GPa pressure conducted at the CRISTAL beamline at the SOLEIL synchrotron is presented in this work. A single crystal was placed in a diamond anvil cell, but owing to its special design (wide opening angle), short synchrotron wavelength and the high symmetry of the crystal, data with high completeness and high resolution were collected. This allowed refinement of a full multipole model of experimental electron distribution. Results are consistent with the benchmark measurement conducted without a diamond-anvil cell and also with the literature describing investigations of similar structures. Results of theoretical calculations of electron density distribution on the basis of dynamic structure factors mimic experimental findings very well. Such studies allow for laboratory simulations of processes which take place in the Earth's mantle.

The three probes of the structure of matter (X-rays, neutrons and electrons) in biology have complementary properties and strengths. The balance between these three probes within their strengths and weaknesses is perceived to change, even dramatically so at times. For the study of combined states of order and disorder, NMR crystallography is also applicable. Of course, to understand biological systems the required perspectives are surely physiologically relevant temperatures and relevant chemical conditions, as well as a minimal perturbation owing to the needs of the probe itself. These remain very tough challenges because, for example, cryoEM by its very nature will never be performed at room temperature, crystallization often requires nonphysiological chemical conditions, and X-rays and electrons cause beam damage. However, integrated structural biology techniques and functional assays provide a package towards physiological relevance of any given study. Reporting of protein crystal structures, and their associated database entries, could usefully indicate how close to the biological situation they are, as discussed in detail in this feature article.

The photovoltaic perovskite, methyl­ammonium lead triiodide [CH3NH3PbI3 (MAPbI3)], is one of the most efficient materials for solar energy conversion. Various kinds of chemical and physical modifications have been applied to MAPbI3 towards better understanding of the relation between composition, structure, electronic properties and energy conversion efficiency of this material. Pressure is a particularly useful tool, as it can substantially reduce the interatomic spacing in this relatively soft material and cause significant modifications to the electronic structure. Application of high pressure induces changes in the crystal symmetry up to a threshold level above which it leads to amorphization. Here, a detailed structural study of MAPbI3 at high hydro­static pressures using Ne and Ar as pressure transmitting media is reported. Single-crystal X-ray diffraction experiments with synchrotron radiation at room temperature in the 0–20 GPa pressure range show that atoms of both gaseous media, Ne and Ar, are gradually incorporated into MAPbI3, thus leading to marked structural changes of the material. Specifically, Ne stabilizes the high-pressure phase of NexMAPbI3 and prevents amorphization up to 20 GPa. After releasing the pressure, the crystal has the composition of Ne0.97MAPbI3, which remains stable under ambient conditions. In contrast, above 2.4 GPa, Ar accelerates an irreversible amorphization. The distinct impacts of Ne and Ar are attributed to differences in their chemical reactivity under pressure inside the restricted space between the PbI6 octahedra.

A gas- and vapour-pressure control system synchronized with the continuous data acquisition of millisecond high-resolution powder diffraction measurements was developed to study structural change processes in gas storage and reaction materials such as metal organic framework compounds, zeolite and layered double hydroxide. The apparatus, which can be set up on beamline BL02B2 at SPring-8, mainly comprises a pressure control system of gases and vapour, a gas cell for a capillary sample, and six one-dimensional solid-state (MYTHEN) detectors. The pressure control system can be remotely controlled via developed software connected to a diffraction measurement system and can be operated in the closed gas and vapour line system. By using the temperature-control system on the sample, high-resolution powder diffraction data can be obtained under gas and vapour pressures ranging from 1 Pa to 130 kPa in temperatures ranging from 30 to 1473 K. This system enables one to perform automatic and high-throughput in situ X-ray powder diffraction experiments even at extremely low pressures. Furthermore, this developed system is useful for studying crystal structures during the adsorption/desorption processes, as acquired by millisecond and continuous powder diffraction measurements. The acquisition of diffraction data can be synchronized with the control of the pressure with a high frame rate of up to 100 Hz. In situ and time-resolved powder diffraction measurements are demonstrated for nanoporous Cu coordination polymer in various gas and vapour atmospheres.

A sample-injection device has been developed at SPring-8 Angstrom Compact Free-Electron Laser (SACLA) for serial femtosecond crystallography (SFX) at atmospheric pressure. Microcrystals embedded in a highly viscous carrier are stably delivered from a capillary nozzle with the aid of a coaxial gas flow and a suction device. The cartridge-type sample reservoir is easily replaceable and facilitates sample reloading or exchange. The reservoir is positioned in a cooling jacket with a temperature-regulated water flow, which is useful to prevent drastic changes in the sample temperature during data collection. This work demonstrates that the injector successfully worked in SFX of the human A2A adenosine receptor complexed with an antagonist, ZM241385, in lipidic cubic phase and for hen egg-white lysozyme microcrystals in a grease carrier. The injection device has also been applied to many kinds of proteins, not only for static structural analyses but also for dynamics studies using pump–probe techniques.

The proton-conducting material (NH4)4H2(SeO4)3 is examined to check whether its conductivity spectra are sensitive to subtle changes in the crystal structure and proton dynamics caused by external pressure. The AC conductivity was measured using impedance spectroscopy, in the frequency range from 100 Hz to 1 MHz, at temperatures 260 K < T < 400 K and pressures 0.1 MPa < p < 500 MPa. On the basis of the impedance spectra, carefully analyzed at different thermodynamic conditions, the p–T phase diagram of the crystal is constructed. It is found to be linear in the pressure range of the experiment, with the pressure coefficient value dTs/dp = −0.023 K MPa−1. The hydrostatic pressure effect on proton conductivity is also presented and discussed. Measurements of the electrical conductivity versus time were performed at a selected temperature T = 352.3 K and at pressures 0.1 MPa < p < 360 MPa. At fixed thermodynamic conditions (p = 302 MPa, T = 352.3 K), the sluggish solid–solid transformation from low conducting to superionic phase was induced. It is established that the kinetics of this transformation can be described by the Avrami model with an effective Avrami index value of about 4, which corresponds to the classical value associated with the homogeneous nucleation and three-dimensional growth of a new phase.

As new allegations emerge about his motives for retirement, Judge Thomas Griffith says that he faced no political pressure in his decision to leave the bench.

"My decision was driven entirely by personal concerns and involved no discussions with the White House or the Senate," he said in a statement provided to NPR.

Griffith said that his wife was diagnosed 11 years ago with a "debilitating chronic illness" and that her health was "the sole reason for my retirement." He said he made the decision to retire in June 2019 and privately informed his family and law clerks at the time. His retirement was announced publicly in March.

Griffith, 65, is a circuit court judge on the U.S. Court of Appeals for the District of Columbia. Appointed by President George W. Bush, he has served since 2005.

On Monday, The New York Times reported that Demand Justice, a liberal judicial advocacy group, filed a complaint that raises questions about whether Griffith's decision was tied to efforts by Senate Majority Leader Mitch McConnell to encourage older, conservative judges to retire in order to fill their vacancies with younger, conservative judges ahead of the 2020 election, when control of the White House and the Senate will be in play.

Griffith's retirement has paved the way for Justin Walker's nomination to fill the vacancy. Walker, 37, is a longtime McConnell ally who is currently serving as a U.S. district judge of the Western District of Kentucky, McConnell's home state.

The Demand Justice complaint was directed to the U.S. Court of Appeals, where the court's chief judge, Sri Srinivasan, has asked Chief Justice John Roberts to assign another circuit to look into the complaint about whether any ethical improprieties occurred. Griffith's statement refutes the core allegation — that his decision was fueled by political considerations or the result of a pressure campaign.

These allegations are likely to come up at Walker's confirmation hearing on Wednesday before the Senate Judiciary Committee.

Democrats broadly oppose Walker's nomination. He was rated "not qualified" by the American Bar Association. However, unless support for him is diminished among Republicans — unlikely with McConnell's backing — he is likely to be confirmed.

A new study reports that fishing depths in the EU have increased, with more deep-sea fish species being harvested. Deep-sea fish populations are often more vulnerable to effects of fishing, and the ecological impact of overfishing may therefore be greater than for shallow-water species.

Fish farming in the Mediterranean has increasingly shifted from producing fish such as grey mullet, which are herbivores near the bottom of the food chain, to species such as sea bass, which are predators. This ‘farming up’ the food chain requires wild fish to be caught to provide feed. A return to farming fish lower in the food chain would use marine resources more efficiently, a new study says.

The pressures facing Indian manufacturers to ‘green’ their supply chain have been explored by a recent study. Both international and national pressures from government and consumers were found to play an important role in whether a company adopts green supply chain management principles, with pressures varying to some degree depending on the business’s sector and size.

Agri-environmental measures (AEM) are designed to encourage farmers to protect and enhance the environment on their farmland by paying them for the provision of environmental services. This study suggests that AEM would be more effective if payments were targeted to areas under the greatest environmental pressures, such as intensive agricultural regions — to gain maximum environmental benefits.

The largest investigation to date into the extent of human-induced pressure on European rivers concludes that around 80% of rivers are affected by water pollution, water removal for hydropower and irrigation, structural alterations and the impact of dams, with 12% suffering from impacts of all four.

The impact that national energy sectors have on international freshwater resources has been demonstrated in the first global study of its kind. The analysis of 129 countries showed differences between countries and sectors in their reliance on international freshwater resources. For example, although the petroleum industries of North America and China are similar in magnitude, the North American industry consumes three times as much international freshwater. Demands from economically developed countries on less economically developed countries, which may have pre-existing water-scarcity issues, compound these problems and complicate the creation of policies that ensure both water and energy security.

Researchers have analysed the policy response to the 2013–2014 flooding of the Somerset Levels and Moors in the UK. Analysis of media coverage and interviews with stakeholders revealed how local pressure promoted dredging — a policy that had fallen out of favour with the national Environment Agency (EA). Although dredging was eventually readopted by the EA, there remain uncertainties over its long-term viability due to funding constraints and debates over its effectiveness.

Human pressures on freshwater resources have seriously reduced the security of water for people and river biodiversity across the world, according to a recent study. Almost 80 per cent of the world's population is at high risk from threats to water security and 65 per cent of river habitats are under threat.

The concept of the Ecological Footprint can be used to illustrate the balance between the use of a natural resource or an ecological service and its availability. According to a new study, the Ecological Footprint could be valuable as an indicator to help track progress towards the goals of the Convention on Biological Diversity.

The combined effects of pollution and rising levels of atmospheric greenhouse gases, including CO₂, may have effects on marine ecosystems that are more damaging than expected, warns new research. The study found that bacteria capable of breaking down oil pollution were far less abundant in sediment in acidified waters. Although increased ultraviolet-B (UV-B) light reduced these negative impacts, the researchers caution that deeper waters or other waters with less UV-B, may still suffer.

High blood pressure is linked to long-term exposure to traffic-related air pollution, new research suggests. After accounting for lifestyle factors, socioeconomic status and pre-existing health conditions, the researchers found that a rise in traffic emissions of nitrogen dioxide corresponded to a rise in blood pressure of exposed individuals.
