Small, adsorbent 'fins' collect humidity rather than swim through water      (via sciencedaily.com)     Original source 

Clean, safe water is a limited resource and access to it depends on local bodies of water. But even dry regions have some water vapor in the air. To harvest small amounts of humidity, researchers developed a compact device with absorbent-coated fins that first trap moisture and then generate potable water when heated. They say the prototype could help meet growing demands for water, especially in arid locations.

Underwater mountains have a big impact on ocean circulation      (via sciencedaily.com)     Original source 

Colossal undersea mountains, towering up to thousands of metres high, stir up deep sea currents: impacting how our ocean stores heat and carbon. An international team used numerical modelling to quantify how underwater turbulence around these mountains, called seamounts, influences ocean circulation; finding it is an important mechanism in ocean mixing and one that is missing from climate models used in policymaking.

Removal of excess chloride ions by plants when subjected to salt stress      (via sciencedaily.com)     Original source 

Researchers have discovered a salt adaptation mechanism in plants that facilitates chloride removal from the roots and enhancing salinity tolerance. A research team has uncovered a novel mechanism of plant adaptation to salt stress involving the NaCl-induced translocation of a specific chloride channel protein, AtCLCf.

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.

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.

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.

Interaction with insects accelerates plant evolution      (via sciencedaily.com)     Original source 

Researchers have discovered that plants benefit from a greater variety of interactions with pollinators and herbivores. Plants that are pollinated by insects and have to defend themselves against herbivores have evolved to be better adapted to different types of soil.

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.

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.

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.

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.

AI shows how field crops develop      (via sciencedaily.com)     Original source 

Researchers developed software that can simulate the growth of field crops. To do this, they fed thousands of photos from field experiments into a learning algorithm. This enabled the algorithm to learn how to visualize the future development of cultivated plants based on a single initial image. Using the images created during this process, parameters such as leaf area or yield can be estimated accurately.

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.

Can engineered plants help make baby formula as nutritious as breast milk?      (via sciencedaily.com)     Original source 

New research may help close the nutrition gap between infant formula and human breast milk. The study shows how plants can be programmed to produce a diverse array of beneficial sugars found in human breast milk. The findings could lead to healthier and more affordable formula for babies, or more nutritious non-dairy plant milk for adults.
