Published Sustainable living technology
(via sciencedaily.com) Original source It is now apparent that the mass-produced artefacts of technology in our increasingly densely populated world – whether electronic devices, cars, batteries, phones, household appliances, or industrial robots – are increasingly at odds with the sustainable bounded ecosystems achieved by living organisms based on cells over millions of years. Cells provide organisms with soft and sustainable environmental interactions with complete recycling of material components, except in a few notable cases like the creation of oxygen in the atmosphere, and of the fossil fuel reserves of oil and coal (as a result of missing biocatalysts). However, the fantastic information content of biological cells (gigabits of information in DNA alone) and the complexities of protein biochemistry for metabolism seem to place a cellular approach well beyond the current capabilities of technology, and prevent the development of intrinsically sustainable technology.
Published Rivers may not recover from drought for years
(via sciencedaily.com) Original source Lack of rainfall is not the only measure of drought. New research shows that despite a series of storms, the impact of drought can persist in streams and rivers for up to 3.5 years.
Published Killer whales' diet more important than location for pollutant exposure
(via sciencedaily.com) Original source Both elegant and fierce, killer whales are some of the oceans' top predators, but even they can be exposed to environmental pollution. Now, in the largest study to date on North Atlantic killer whales, researchers report the levels of legacy and emerging pollutants in 162 individuals' blubber. The animals' diet, rather than location, greatly impacted contaminant levels and potential health risks -- information that's helpful to conservation efforts.
Published 'Ultrashort' PFAS compounds detected in people and their homes, study shows
(via sciencedaily.com) Original source Per- and polyfluoroalkyl substances (PFAS) have become ubiquitous throughout the environment, and increasing evidence has demonstrated their deleterious effects. A group of smaller, fluorinated compounds are becoming replacements for these 'forever chemicals,' though research suggests the smaller versions could also be harmful. Now, a study reports that the levels of these substances in many indoor and human samples are similar to or higher than those of legacy PFAS.
Published Remains of artificial turf is an important source of pollution of the aquatic environment
(via sciencedaily.com) Original source Every year, around 1,200 and 1,400 artificial turf sports fields are installed in the European Union. These fields are made up of synthetic fibers, mainly plastics, that mimic the appearance of natural grass. Recently, scientists conducted a study that characterizes and quantifies the presence of artificial turf fibers in samples collected from surface waters of the Catalan coast and the Guadalquivir River. The findings indicate that artificial turfs can be an important source of pollution in the aquatic environment, accounting for up to 15% of the plastics larger than 5 mm in length that are found floating in the aquatic environment.
Published Plastic use in agriculture must be reduced, according to new research
(via sciencedaily.com) Original source Plastic use in agriculture must be reduced in order to mitigate pollution and prevent toxic chemicals from leaching into the soil and adversely affecting human health, according to a new study.
Published Warm summers and wet winters yield better wine vintages
(via sciencedaily.com) Original source Wine quality is notorious for varying from year to year, but what makes for a 'good year?' Researchers show that weather plays an important role in determining wine quality. By analyzing 50 years’ worth of wine critic scores from the Bordeaux wine region in relation to that year’s weather, the researchers showed that higher quality wine is made in years with warmer temperatures, higher winter rainfall, and earlier, shorter growing seasons—conditions that climate change is predicted to make more frequent.
Published Titanium oxide material can remove toxic dyes from wastewater
(via sciencedaily.com) Original source Discharged in large quantities by textile, cosmetic, ink, paper and other manufacturers, dyes carry high-toxicity and can bring potential carcinogens to wastewater. It’s a major concern for wastewater treatment — but researchers may have found a solution, using a tiny nanofilament.
Published Paleoclimatologists use ancient sediment to explore future climate in Africa
(via sciencedaily.com) Original source With global warming apparently here to stay, a team of paleoclimatologists are studying an ancient source to determine future rainfall and drought patterns: fossilized plants that lived on Earth millions of years ago.
Published Modular dam design could accelerate the adoption of renewable energy
(via sciencedaily.com) Original source Scientists have developed a new modular steel buttress dam system designed to resolve energy storage issues hindering the integration of renewable resources into the energy mix. The new modular steel buttress dam system facilitates the rapid construction of paired reservoir systems for grid-scale energy storage and generation using closed-loop pumped storage hydropower, cutting dam construction costs by one-third and reducing construction schedules by half.

Published Researchers identify largest ever solar storm in ancient 14,300-year-old tree rings
(via sciencedaily.com) Original source An international team of scientists have discovered a huge spike in radiocarbon levels 14,300 years ago by analyzing ancient tree-rings found in the French Alps. The radiocarbon spike was caused by a massive solar storm, the biggest ever identified. A similar solar storm today would be catastrophic for modern technological society – potentially wiping out telecommunications and satellite systems, causing massive electricity grid blackouts, and costing us billions. The academics are warning of the importance of understanding such storms to protect our global communications and energy infrastructure for the future.
