While every mode of transportation in the U.S. will be affected as the climate changes, potentially the greatest impact on transportation systems will be flooding of roads, railways, transit systems, and airport runways in coastal areas because of rising sea levels and surges brought on by more intense storms, says a new report from the National Research Council.

The call for expanding undergraduates’ access to research experiences in science, technology, engineering, and mathematics (STEM) raises questions about their use and potential to increase students’ interest and persistence in these disciplines.

Federal agencies or other organizations responsible for sponsoring research or collecting data on technology and the workforce should establish a multidisciplinary research program that addresses unanswered questions related to the impact of changing technology on the nature of work and U.S. national economy, says a new report by the National Academies of Sciences, Engineering, and Medicine.

The Gulf Research Program (GRP) of the National Academies of Sciences, Engineering, and Medicine today announced 11 grant awards totaling $341,283 to assist in the recovery of Gulf Coast scientific research efforts impacted by hurricanes Harvey and Irma.

The Gulf Research Program (GRP) of the National Academies of Sciences, Engineering, and Medicine today announced 11 grant awards totaling $287,565 to assist in the recovery of Gulf of Mexico region scientific research efforts impacted by hurricanes Harvey and Irma.

A new report from the National Academies of Sciences, Engineering, and Medicine examines the effects and efficacy of using dispersants in marine oil spill response.

We tend to think of the process of seeing as fairly objective — that our eyes are similar to cameras, neutrally taking in light and turning it into pictures. But research has shown that biases buried beneath our awareness can powerfully shape how we see.

The status of soil can be represented by many properties. However, how well they represent soil status depends on the level of rainfall in the area. Researchers in Spain found that in wet regions soil status is strongly linked to biological factors, such as vegetation cover and biodiversity. In drier regions, status has a stronger link to the physical properties of the soil.

A recent study has demonstrated that it is possible to identify which human pressures, such as fisheries and environmental pollution, are causing changes in Marine and Coastal by combining the trends in different indicators. This approach can be used as a tool for integrated ecosystem assessment and management.

Understanding the impacts of human activities on Marine and Coastal is important to ensure their sustainability. New research has indicated that seafloor ecosystems are less likely to recover from fishing if they are in rocky or reef habitats and if dredging and bottom trawling equipment is used for shellfish and various fish species. When fishing is combined with the extraction of aggregate for mineral resources, the impacts are even more damaging.

The effects of seafloor trawling can extend further than the immediate fishing grounds, affecting delicate deep-sea ecosystems, new research suggests. In this Mediterranean study, the researchers demonstrated that clouds of sediment from trawling reached deeper habitats, increasing water-borne sediment particle concentrations to a hundred times that of background levels.

Seabed fishing grounds in the UK are made up of intensively fished core areas surrounded by more rarely used marginal areas, new research shows. Excluding these margins, which contain only 10% of the total fishing activity, approximately halves the total area of fishing grounds. Thus reducing the fishing footprint by closing the marginal areas will disproportionately reduce the seabed impact of fishing activity.

Municipal solid waste (MSW) landfills, which consist of everyday consumer items, are potential long-term sources of emissions that could threaten the environment and human health if they are not managed carefully after closure. New research has presented a methodology to estimate future emission levels for closed MSW landfills and the impact of different aftercare strategies.

A recent study has assessed the lifecycle environmental impact during the production and use phase of three battery types for plug-in hybrid (PHEV) and full performance battery electric vehicles (BEV). The study indicates that newer lithium-ion (Li-ion) technologies outperform current nickel-metal hydride (NiMH) batteries and identifies processes contributing to 13 environmental impacts

Researchers have developed a new model to assess the health-related external costs arising from air pollution from ten major emission sectors. Applying the model at national and Europe-wide levels, they suggested that the major contributors to costs were industrial power production, agriculture, road traffic and domestic combustion.

The global production, trade and use of goods and services has a significant impact on the environment — and rates of consumption are rising. A new study combines two assessment methods to quantify the impact of European trade on the environment. It finds that, overall, the EU was a net importer of environmental impact from 2000 to 2010, that machinery, equipment and vehicles contributed most to the EU’s export impacts and that the EU’s trade balance (import impact minus export impact) is increasing over time. The two assessment methods complement one another well and could form the basis for future country or region-wide studies, suggest the researchers, by enabling a detailed analysis of individual steps within a product’s trade flow, while also providing a larger picture of the overall process.

As 3D printing, also known as additive manufacturing (AM), begins to replace conventional manufacturing, the environmental impacts of its implementation must be assessed. This study conducted a life cycle assessment (LCA) to investigate the environmental and resource implications of using AM to manufacture the metal parts of an engine in a light distribution truck. In the LCA, the impacts of both present and possible future states of AM technology were compared with current conventional manufacturing. The results suggest that there are potential environmental and resource benefits1 to AM technologies, but that these benefits rely on the achievement of a clean energy source and further technological development.

New research has compared the environmental impact of four alternative methods of water supply in Copenhagen. Results indicated that rain and stormwater harvesting is the most environmentally sound approach, whilst desalination currently has a large environmental impact, mainly due to electricity use. However, if freshwater extraction is included as an impact, the environmental credibility of desalination is improved.

A recent study has compared the environmental impact of a range of building materials. Energy consumption, carbon dioxide emissions and water demand can all be reduced by switching to renewable sources of energy, improving technologies and promoting eco-friendly alternative materials.

New research has assessed the environmental impact of gold production using life cycle assessment and estimated embodied energy and greenhouse gases, embodied water and solid waste burden that each tonne of gold produces, using various processes.

As the media environment changes, the way scientists communicate their work must also evolve. This study explored the effect of public communication on the scientific ‘impact’ of America’s most highly cited nanotechnology researchers. It provides the first evidence that outreach activities, such as speaking to journalists and being mentioned on Twitter, can increase a scientist’s impact.

Sea level rise may cause soils in coastal regions to become more saline. In a recent study, reproduction in soil invertebrates was impaired in soils containing salt levels below the threshold used currently to define saline soils. The authors recommend community-level studies to further investigate the salt concentrations that are harmful to soil organisms.

A recent EU-supported study has analysed the development of volunteer or ‘rogue’ GM (genetically modified) maize plants in a conventional crop field. It finds that their numbers are low and do not exceed the EU’s threshold of 0.9 per cent for incidental GM content.

A recent study has compared the chemical environmental impacts of using the weed controller glyphosate on glyphosate-tolerant (GT) crops, with the use of other herbicides on non-GT crops. Glyphosate used on GT crops had lower environmental impacts than herbicides used on non-GT crops, but the persistence of AMPA (a break-down product of glyphosate) in soils could be a problem in the future.

The number and impacts of disasters have increased in Europe in the period 1998-2009, a new report by the European Environment Agency (EEA) concludes. The report assesses the frequency of disasters and their impacts on humans, the economy and ecosystems and calls for better integrated risk management across Europe.

The damaging health impacts of some key air pollutants can occur at lower atmospheric concentrations than indicated by the most recent World Health Organization (WHO) Air Quality guidelines, set in 2005 and currently used in Europe. This is according to a new WHO report, which assesses scientific evidence to help inform European air pollution policies.

Exposure to excessive noise is recognised as a major environmental health concern. This Thematic Issue examines the impact of noise on human health and outlines how policy initiatives may limit health effects from noise annoyance - and improve wellbeing.

Exposure to aircraft noise at night for more than 20 years could increase the risk of heart disease and stroke, according to research conducted around six European airports. Risk also increased for those constantly exposed to road traffic, but this may have been caused by air pollution rather than noise.

People living close to road, rail and aircraft noise are likely to experience negative health effects. Long-term noise exposure may lead to problems with their heart and circulatory (cardiovascular) system and night-time noise is particularly disruptive of sleep patterns, which in turn may lead to cardiovascular health problems, a review of research into the effects of noise on cardiovascular diseases has found.

While occupational exposure to noise has declined, ‘social’ exposure in the form of personal music players or rock concerts is estimated to have tripled for young people since the 1980s. A new review examines studies that have investigated noise sources, including environmental (e.g. traffic) and social (e.g. via headphones) sources. The review also explores research into the range of health effects beyond hearing impairments, such as annoyance and cardiovascular problems.

Standards for environmental management, such as EMAS and ISO 14001, aim to help organisations become more sustainable, but they have received little evaluation. A new Italian study is the first to quantitatively compare the impacts of these two standards. Its results suggest that EMAS's stipulation that organisations must report their ongoing performance may bring sustained environmental benefits in the longer term.

New insights into the impact of dredging on the environment highlight the distinction between small, frequent deposits of sediments arising from maintenance dredging, and larger one-off capital deposits. Understanding this distinction is crucial for effective licensing and monitoring of dredging.

Environmental impact studies which are conducted early on in the development of wave and tidal-power schemes allow the schemes' technology to be adapted to consider their impacts on marine ecosystems, according to a recent study which reports on a Swedish research wave park.

A recent study in Finland suggests new building regulations will lead to a substantial reduction in the total energy demand and CO2 emissions in new apartment buildings. This could have an impact on the source of energy used for new buildings. In particular, the demand for space heating will fall, which could have an impact on the source of energy used for new buildings.

A new study highlights the environmental impact of beef produced from specialist meat production based on suckler herds, as opposed to that based on the calves of dairy cows. According to the study, beef produced in this way has a greater impact in terms of greenhouse gas (GHG) emissions, acidification and eutrophication potential, and on land use.

The impact of climate change on electricity consumption is important to both adaptation and mitigation policies. New research has estimated that over the next 100 years climate change could cause up to a 20 per cent decrease in demand for electricity for heating in Northern Europe and up to a 20 per cent increase in demand for electricity for cooling in Southern Europe.

A new study assesses the potential impacts of climate change on human health in the Netherlands. The researchers conducted a survey, asking health experts to rate the level of uncertainty attached to different health impacts of climate change, which highlighted heat-related deaths and vector-borne diseases as particularly relevant to climate change adaptation.

When assessing the environmental impacts of new ‘green’ concretes, care should be taken to ensure that a range of impacts are considered, such as ecosystem damage and water depletion, rather than a sole focus on CO2 emissions, a recent study concludes. It demonstrates that cement incorporating industrial by-products performs substantially better than Portland cement when rated across several classifications of environmental impact.

The world’s ocean ecosystems will suffer warming, increased acidity, low oxygen and reduced primary food supply as a result of rising CO2 and this is likely to have dramatic environmental and social impacts, a new study concludes. It predicts that the most vulnerable low-income countries, where 870 million people are dependent on marine ecosystems, would be affected if CO2 emissions are not tackled.

The greenhouse gas (GHG) emissions produced during the decommissioning phase of nuclear power plants may have been underestimated in previous assessments, new research suggests. The study estimated that the decommissioning process for a German plant resulted in 1 651 265 tonnes of CO₂ (or equivalent) emissions, or 0.825 tonnes of CO2 equivalent per tonne of waste. While the researchers acknowledge that impact is highly dependent on the unique characteristics of each decommissioning project, these results raise questions as to whether this phase has been accurately assessed in earlier research.

Municipal solid waste (MSW) landfills, which consist of everyday consumer items, are potential long-term sources of emissions that could threaten the environment and human health if they are not managed carefully after closure. New research has presented a methodology to estimate future emission levels for closed MSW landfills and the impact of different aftercare strategies.

A new study has shown that contamination of groundwater by hazardous substances contained in waste liquid from landfill sites – known as leachate - could be significantly reduced by choosing specific types of material to line the landfill reactors.

Life-cycle indicators to monitor selected waste streams' impacts on the environment have been developed by the European Commission’s Joint Research Centre (JRC). These are presented in a recent study which describes a method for analysing waste's impacts using these indicators. The study also reveals the need for better statistics and more detailed categorisation of waste streams to effectively inform decision making in waste management.

Life cycle assessment (LCA) can measure the environmental impact of the different stages of a ship’s life cycle, from design to dismantling. This assessment focused on the impact of recycling the metal parts of a ship and did not consider the crucial impact of the hazardous materials present on board. The results showed that re-use of metals had environmental benefits, but overall these were small compared to the environmental impact of other life cycle stages, such as operation.

Researchers have examined environmental and economic impacts of supermarket food waste in a new study. Bread and meat products made the largest contribution to the environmental footprint of the supermarket assessed. Alternative waste strategies, such as using bread waste as animal feed, have the potential to reduce these impacts.
