How do rootstocks mediate scion salinity tolerance under salt stress?
Grafting in tomato has been investigated mainly in small-scale experiments, demonstrating morphological, physiological, and metabolic changes in the scion mediated by the rootstock. By grafting a scion onto different rootstocks, scion salt tolerance.....»»
First maps of the fens of eastern England reveal saltwater that could threaten food production
The first ever maps of the shallow groundwater of the Fens of eastern England show that salt water is relatively close beneath the surface, meaning that if sea-levels rise, then salt content would affect the ability of the area to grow food......»»
New monovalent anion permselective membranes for high-efficient mono-/di-valent anion separation
Monovalent anion perm-selective membranes (MAPMs) combined with electrodialysis can simultaneously realize the efficient separation of mono-/di-valent anions and the concentration of monovalent salt. However, their applications in practical industria.....»»
The American West’s Salt Lakes Are Turning to Dust
A new research and monitoring program aims to conserve threatened but overlooked saline ecosystems......»»
A smart elastomer that can self-tune its stiffness and conductivity
Smart materials are materials that have the ability to change their properties in response to specific external stimuli, such as temperature, humidity, light, or applied stress. One of the most well-known examples of smart materials is shape memory a.....»»
Heat stress is rising in southern Africa—climate experts show where and when it"s worst
Most of us have felt either too hot or too cold at some point in our lives. Depending on where we live, we may feel too cold quite often each winter, and too hot for a few days in summer. As we're writing this in late January 2023 many southern Afric.....»»
One facility makes a big contribution to Salt Lake"s winter brown cloud
The 2.4 million people who live along Utah's Wasatch Front experience some of the most severe winter particulate matter air pollution in the nation. Now, analysis of measurements taken during National Oceanic and Atmospheric Administration (NOAA) res.....»»
The cost of school uniforms is a barrier to education, but there are ways to level the playing field
This year's perennial back-to-school uniform discussion happens during a cost of living crisis. And we already know that the upfront and maintenance costs of school uniforms are a stress for families on lower incomes, in New Zealand and globally acro.....»»
Stress may trigger male crucian carp defense against predators
Only males among the fish species crucian carp have developed a strategy to protect themselves from hungry predators, according to a new study from Lund University in Sweden published in the journal Evolution. The explanation could lie in that the su.....»»
A rainbow of force-activated pigments for identifying stress
Stress isn't just the psychological pressure you feel in response to a looming deadline at work. It is also a description of the physical forces pushing, pulling, or twisting an object, structure, or material. Examples of stress include gravity dragg.....»»
Ascertaining the most effective silicon fertilization strategy to boost olive tree defenses
Despite not being an essential element for plant growth, silicon increases plants' tolerance of biotic stresses, such as pests and diseases; and abiotic ones, such as drought and salinity. The effects of this element, the second most abundant in the.....»»
How habanero peppers respond to stress
Like people, plants have to cope with stress. The impact on humans is well catalogued, but less is known about how stressors—including high salinity and lack of nutrients—affect plants such as habaneros. Now, researchers report in ACS Agricultura.....»»
Simulations and experiments reveal unprecedented detail about water"s motion in salt water
In salt water solutions, water molecules rapidly move around salt ions at a scale of more than a trillion times a second, according to both experiments and simulations led by scientists at New York University and the Sorbonne......»»
Electrical properties of bacteria: How membrane potential influences antibiotic tolerance
The electrical potential across the bacterial cell envelope indicates when bacteria no longer operate as individual cells but as a collective. Researchers at the University of Cologne's Institute for Biological Physics have discovered this connection.....»»
How mycorrhizal types control biodiversity effects on productivity
Mycorrhizal symbiosis helps plants expand their root surface area, giving plants greater access to nutrients and water. Although the first and foremost role of mycorrhizal symbiosis is to facilitate plant nutrition, how mycorrhizal types mediate the.....»»
Genetically modified rice could be key to tackling food shortages caused by climate change
As sea levels rise as a result of climate change, more and more places around the world are struggling with seawater inundation—where salt water from the sea is flooding further inland and destroying crops which can't cope with the increased salini.....»»
This cool new approach to refrigeration could replace harmful chemicals
New method uses salt and an organic solvent to change a material’s melting point. Enlarge / Berkeley Lab scientists have developed ionocaloric cooling, a new refrigeration cycle they hope could help phase out refrigerants that.....»»
As climate warms, drier air likely to be more stressful than less rainfall for Douglas-fir trees
Douglas-fir trees will likely experience more stress from drier air as the climate changes than they will from less rain, computer modeling by Oregon State University scientists shows......»»
Landscaping for drought: We"re doing it wrong
Despite recent, torrential rains, most of Southern California remains in a drought. Accordingly, many residents plant trees prized for drought tolerance, but a new UC Riverside-led study shows that these trees lose this tolerance once they're watered.....»»
Continued record-breaking ocean temperatures seen again in 2022
Continued record-breaking ocean temperatures with increasing stratification and changes in water salinity patterns give insight into what the future holds amidst a perpetually heating climate......»»
Study identifies gene that may reduce chalkiness of heat-stressed rice
Oppressive temperatures can curb the growth and yields of multiple cereal crops, including rice, which is eaten by some 3.5 billion people worldwide. Though much of the research into heat stress has investigated its effects on quantity, it can degrad.....»»
