Towards smart cities: Predicting soil liquefaction risk using artificial intelligence      (via sciencedaily.com)     Original source 

Soil liquefaction that results in infrastructure damage has long been a point of contention for urban planners and engineers. Accurately predicting the soil liquefaction risk of a region could help overcome this challenge. Accordingly, researchers applied artificial intelligence to generate soil liquefaction risk maps, superseding already published risk maps.

3D models provide unprecedented look at corals' response to bleaching events      (via sciencedaily.com)     Original source 

Marine biologists are providing a glimpse into coral 'bleaching' responses to stress, using imaging technology to pinpoint coral survival rates following multiple bleaching events off the island of Maui. Using a time series of coral reef 3D models from Maui, the researchers tracked the bleaching response of 1,832 coral colonies from 2014 to 2021. The seven-year data set provided detailed imagery of the reefs year-by-year, allowing the team to identify patterns of coral growth and survivorship through sequential bleaching events that occurred in 2015 and 2019.

Downwind states face disproportionate burden of air pollution      (via sciencedaily.com)     Original source 

A recent U.S. Supreme Court decision to block a federal rule curbing interstate air pollution further complicates efforts to reduce emissions and adds to an already disproportionate burden on 'downwind' states, according to researchers.

Smell reports reveal the need to expand urban air quality monitoring, say researchers      (via sciencedaily.com)     Original source 

Researchers have uncovered surprising insights into the Vancouver region's 'smellscape' using data from the Smell Vancouver app. Analyzing 549 reports from one year of app data, they discovered that 'rotten' and 'chemical' odours dominated, making up about 65 per cent of submissions. These unpleasant smells were linked to self-reported health issues like headaches and anxiety, leading some residents to change their behaviours, like closing windows even in stifling-hot weather.

What's the weather like in the deep sea?      (via sciencedaily.com)     Original source 

A new study has revealed how even the deepest seafloors are affected by the daily back-and-forth of the tides, and the change of the seasons, and that currents at the bottom of the ocean are far more complicated than previously thought. These findings are helping us understand the deep-sea pathways of nutrients that support important deep-sea ecosystems, assess where microplastics and other pollutants accumulate in the ocean, and reconstruct past climate change.

Researchers explore the potential of clean energy markets as a hedging tool      (via sciencedaily.com)     Original source 

Clean energy investments offer potential stability and growth, especially during volatile market conditions. A recent study explored the relationship between clean energy markets and global stock markets. Significant spillovers were observed from major indices like the SP500 to markets such as Japan's Nikkei225 and Global Clean Energy Index. These interactions suggest opportunities for optimizing investment portfolios and leveraging clean energy assets as hedging tools in volatile market environments.

North Sea oil and gas extraction spikes pollution by 10,000 percent, study finds      (via sciencedaily.com)     Original source 

North Sea oil and gas extraction can cause pollution to spike by more than 10,000 percent within half a kilometer around off-shore sites, a study has found. The research has uncovered the true impact on Britain's seabed life -- with the number of species plummeting nearly 30 percent near platforms.

Organic nanozymes have broad applications from food and agriculture to biomedicine      (via sciencedaily.com)     Original source 

Nanozymes are tiny, engineered substances that mimic the catalytic properties of natural enzymes, and they serve a variety of purposes in biomedicine, chemical engineering, and environmental applications. They are typically made from inorganic materials, including metal-based elements, which makes them unsuitable for many purposes due to their toxicity and high production costs. Organic-based nanozymes partially overcome some of these problems and have the potential for a broader range of applications, including food and agriculture, but they are still in the early stages of development. A new paper provides an overview of the current state of organic nanozymes and their future potential.

How researchers turn bacteria into cellulose-producing mini-factories      (via sciencedaily.com)     Original source 

Researchers have modified certain bacteria with UV light so that they produce more cellulose. The basis for this is a new approach with which the researchers generate thousands of bacterial variants and select those that have developed into the most productive.

Is that glass bottle of OJ better for the planet than a plastic container?      (via sciencedaily.com)     Original source 

Which packaging type for a 12-ounce, single-serve container of orange juice would you choose as the most sustainable option: Aluminum/canned, made with recycled material; Carton, described as biodegradable/compostable; Glass, 100% recyclable; or Plastic, described as biodegradable/compostable? If you were like the U.S. consumers surveyed by food scientists you'd prefer glass and believe it was the most sustainable choice. And you all would be mistaken.

NASA data shows July 22, 2024 was Earth's hottest day on record      (via sciencedaily.com)     Original source 

July 22, 2024, was the hottest day on record, according to a NASA analysis of global daily temperature data. July 21 and 23 of this year also exceeded the previous daily record, set in July 2023. These record-breaking temperatures are part of a long-term warming trend driven by human activities, primarily the emission of greenhouse gases.

Local food production saves costs and carbon      (via sciencedaily.com)     Original source 

Emphasizing local food production over imported substitutes can lead to significant cost and carbon savings, according to data from the Inuvialuit Settlement Region in the Canadian Arctic. The research shows potential annual savings of more than 3.1 million Canadian dollars and roughly half the carbon emissions when locally harvested food is used instead of imported food. The study underscores the importance of climate change policies that take local food systems into account. Weakening of these local systems could lead to increased emissions and jeopardize the health and food security of remote communities.

Bold moves needed for California agriculture to adapt to climate change      (via sciencedaily.com)     Original source 

California needs urgent and bold measures to adapt its $59 billion agriculture sector to climate change as the amount of water available for crops declines, according to a new report. The report provides a roadmap for more water capture, storage, and distribution systems that are in harmony with climate projections and ecosystems. It further considers how runoff and groundwater can be used repeatedly as it flows generally from mountainsides to coastal lands.
