Published New study confirms forever chemicals are absorbed through human skin
(via sciencedaily.com) Original source A study of 17 commonly used synthetic 'forever chemicals' has shown that these toxic substances can readily be absorbed through human skin.
Published Carbon dioxide's heavy stamp on temperature: Doubling CO2 may mean 7 to 14 degree increase
(via sciencedaily.com) Original source A doubling of the amount of CO2 in the atmosphere could cause an increase in the average temperature on earth from 7 to even a maximum of 14 degrees. That is shown in the analysis of sediments from the Pacific Ocean off the coast of California.
Published Promise green hydrogen may not always be fulfilled
(via sciencedaily.com) Original source Green hydrogen often, but certainly not always, leads to CO2 gains.
Published Up to 30 percent more time: Climate change makes it harder for women to collect water, study finds
(via sciencedaily.com) Original source By 2050, climate change could increase the amount of time women in households without running water spend collecting water by up to 30 percent on global average, according to a new study. In regions of South America and Southeast Asia, the time spent collecting water could double due to higher temperatures. Scientists estimate the large welfare losses that could result from climate impacts and highlights how women are particularly vulnerable to changing future climate conditions.
Published Restoring the Great Salt Lake would have environmental justice as well as ecological benefits
(via sciencedaily.com) Original source Inland seas around the world are drying up due to increasing human water use and accelerating climate change, and their desiccation is releasing harmful dust that pollutes the surrounding areas during acute dust storms. Using the Great Salt Lake in Utah as a case study, researchers show that dust exposure was highest among Pacific Islanders and Hispanic people and lower in white people compared to all other racial/ethnic groups, and higher for individuals without a high school diploma. Restoring the lake would benefit everyone in the vicinity by reducing dust exposure, and it would also decrease the disparities in exposure between different racial/ethnic and socioeconomic groups.
Published New NOvA results add to mystery of neutrinos
(via sciencedaily.com) Original source The international collaboration presented their first results with new data in four years, featuring a new low-energy sample of electron neutrinos and a dataset doubled in size.
Published Much of the Nord Stream gas remained in the sea
(via sciencedaily.com) Original source Much of the methane released into the southern Baltic Sea from the Nord Stream gas pipeline has remained in the water. This is shown by measurements taken by researchers from the University of Gothenburg.
Published When in drought: Researchers map which parts of the Amazon are most vulnerable to climate change
(via sciencedaily.com) Original source Some areas of the Amazon rainforest are more resilient to drought than others, new research shows. But if not managed carefully, we could 'threaten the integrity of the whole system,' researchers say.
Published Breakthrough may clear major hurdle for quantum computers
(via sciencedaily.com) Original source The potential of quantum computers is currently thwarted by a trade-off problem. Quantum systems that can carry out complex operations are less tolerant to errors and noise, while systems that are more protected against noise are harder and slower to compute with. Now a research team has created a unique system that combats the dilemma, thus paving the way for longer computation time and more robust quantum computers.
Published Advanced artificial intelligence: A revolution for sustainable agriculture
(via sciencedaily.com) Original source The rise of advanced artificial intelligence (edge AI) could well mark the beginning of a new era for sustainable agriculture. A recent study proposes a roadmap for integrating this technology into farming practices. The aim? To improve the efficiency, quality and safety of agricultural production, while addressing a range of environmental, social and economic challenges.
Published New material puts eco-friendly methanol conversion within reach
(via sciencedaily.com) Original source Researchers have developed innovative, eco-friendly quantum materials that can drive the transformation of methanol into ethylene glycol. This discovery opens up new possibilities for using eco-friendly materials in photocatalysis, paving the way for sustainable chemical production.
Published Climate change: rising temperatures may impact groundwater quality
(via sciencedaily.com) Original source As the world's largest unfrozen freshwater resource, groundwater is crucial for life on Earth. Researchers have investigated how global warming is affecting groundwater temperatures and what that means for humanity and the environment. Their study indicates that by 2100, more than 75 million people are likely to be living in regions where the groundwater temperature exceeds the highest threshold set for drinking water by any country.
Published An earthquake changed the course of the Ganges: Could it happen again?
(via sciencedaily.com) Original source A major earthquake 2,500 years ago caused one of the largest rivers on Earth to abruptly change course, according to a new study. The previously undocumented quake rerouted the main channel of the Ganges River in what is now densely populated Bangladesh, which remains vulnerable to big quakes.
Published Wear it, then recycle: Designers make dissolvable textiles from gelatin
(via sciencedaily.com) Original source Researchers hope their DIY machine will help designers around the world experiment with making their own, sustainable fashion and other textiles from a range of natural ingredients -- maybe even the chitin in crab shells or agar-agar from algae.
Published Improving soil health yields unexpected benefits for farmers
(via sciencedaily.com) Original source While farmer surveys suggest that carbon prices are still too low relative to the paperwork these programs demand, a new study finds that money alone does not explain either farmers' doubts about carbon markets or their interest in regenerative agriculture. Instead, many farmers view improving soil health as a way to improve their quality of life by reducing their dependence on agrochemical companies' products and advice.
Published Quantum entanglement measures Earth rotation
(via sciencedaily.com) Original source Researchers carried out a pioneering experiment where they measured the effect of the rotation of Earth on quantum entangled photons. The work represents a significant achievement that pushes the boundaries of rotation sensitivity in entanglement-based sensors, potentially setting the stage for further exploration at the intersection between quantum mechanics and general relativity.
Published A liquid crystal source of photon pairs
(via sciencedaily.com) Original source Spontaneous parametric down-conversion (SPDC), as a source of entangled photons, is of great interest for quantum physics and quantum technology, but so far it could be only implemented in solids. Researchers have demonstrated, for the first time, SPDC in a liquid crystal. The results open a path to a new generation of quantum sources: efficient and electric-field tunable.
Published Pair plasmas found in deep space can now be generated in the lab
(via sciencedaily.com) Original source Researchers have experimentally generated high-density relativistic electron-positron pair-plasma beams by producing two to three orders of magnitude more pairs than previously reported.
Published The yuck factor counteracts sustainable laundry habits
(via sciencedaily.com) Original source Most people today would lean towards environmentally friendly life choices, but not at the expense of being clean. When it comes to our washing habits, the fear of being perceived as dirty often wins out over the desire to act in an environmentally friendly way. And the more inclined we are to feel disgusted, the more we wash our clothes. This is shown by a unique study that examines the driving forces behind our laundering behaviours and provides new tools for how people's environmental impact can be reduced.
Published Scientists unravel drivers of the global zinc cycle in our oceans, with implications for a changing climate
(via sciencedaily.com) Original source The understanding of the global zinc cycle in our oceans has important implications in the context of warming oceans. A warmer climate increases erosion, leading to more dust in the atmosphere and consequently more dust being deposited into the oceans. More dust means more scavenging of zinc particles, leading to less zinc being available to sustain phytoplankton and other marine life, thereby diminishing the oceans' ability to absorb carbon.
