Pseudobulbs: sink for exogenous nitrogen in epiphytic orchids
Pseudobulbs, which are somewhat enlarged or thickened succulent stems, are common in epiphytic orchids. Nitrogen can be transported from old to young pseudobulbs and between leaves and pseudobulbs......»»
Sulfur-cycling microbes could lead to new possibilities in river-wetland-ocean remediation
Nutrient cycles such as the carbon, nitrogen, phosphorous and sulfur cycles are critical processes that free up elements essential to life by recycling them through our water, air, and soil. Sulfur, specifically, is an integral element in producing a.....»»
Meteorites likely source of nitrogen for early Earth, Ryugu samples study finds
Micrometeorites originating from icy celestial bodies in the outer solar system may be responsible for transporting nitrogen to the near-Earth region in the early days of our solar system. That discovery was published in Nature Astronomy by an intern.....»»
Low-pH-dependent RNA binding and oligomerization of SID-1 transmembrane family proteins: Implications for RNA transport
In C. elegans, the protein SID1 plays a crucial role in the systemic RNA interference process by facilitating the transport of exogenous double-stranded RNA into the cytoplasm. Previously, Chen-Yu Zhang's group has already demonstrated that intact pl.....»»
Investigating solid-state atomic hydrogen as a potential hydrogen therapy strategy
The overexpression of reactive oxygen and nitrogen species (RONS) is closely associated with the onset and progression of diverse chronic diseases, such as cancer, Alzheimer's disease, and chronic diabetic ulcers. Hydrogen therapy, as an emerging and.....»»
Unique weather phenomenon may have helped Ukraine identify and sink Russian ship Moskva
A pair of radar experts at Swedish Defense Research working with a meteorologist from the Swedish Meteorological and Hydrological Institute has found evidence suggesting that the reason the Ukrainian military was able to spot and sink a distant Russi.....»»
iPhone 16 to use graphene heat sink to solve overheating issues
Users complained of overheating iPhone 15 models shortly after release, which Apple fixed via software, but the iPhone 16 is rumored to have a hardware solution, too.iPhone 15 Pro had an overheating problemSelect iPhone 15 and iPhone 15 Pro models co.....»»
Seagrass decline poses issues for carbon storage projects
Climate change is an ever-pressing concern, with innovative ways to remove excess carbon from the atmosphere a continued focus of scientists. One such carbon sequestration method turns to an unlikely sink—seagrass—a marine flowering plant (angios.....»»
Cultivation of grass significantly reduces nitrogen leaching from cultivated peatlands: Study
Perennial grass cover significantly reduces nitrogen leaching from cultivated peatlands, according to a recent study published in Science of The Total Environment. In measurements of Ruukki NorPeat field, the least amount of nitrogen was leached from.....»»
Scientists map loss of groundwater storage around the world
Global water resources are stretched by climate change and human population growth, and farms and cities are increasingly turning to groundwater to fill their needs. Unfortunately, the pumping of groundwater can cause the ground surface above to sink.....»»
Realizing in situ electron paramagnetic resonance spectroscopy using single nanodiamond sensors
Researchers have used the nitrogen-vacancy (NV) center inside a single nanodiamond for quantum sensing to overcome the problem of random particle rotation. Their study is published in Nature Communications......»»
The true costs of corn
A model examines farmers' profits and the health and environmental costs of growing corn in the US Midwest, where about 20% of the world's corn is grown. Corn farming involves applying fertilizer or manure to provide the crop with nitrogen, a vital n.....»»
New ammonia reaction could offer a sustainable source of nitrogen
A big goal in chemistry is to find a simple way to produce amines from ammonia and unsaturated hydrocarbons. Catalytic addition to activate and transfer ammonia would not give rise to any waste. Hence, the process would be sustainable......»»
China"s "Great Green Wall" boosts carbon sink, study finds
Since 1978, China has been building a "Great Green Wall" of trees and shrubs across its arid and semi-arid regions to combat desertification and improve the environment. Known as the Three-North Afforestation Program (TNAP), it is the largest ecologi.....»»
Researchers: There is a need for more accurate accounting of nitrous oxide from agricultural crop residues
There is a need for changing the way of accounting greenhouse gases from agriculture. The current inventory of nitrous oxide from plant residues relies solely on the amount of nitrogen in the residues, while crucial factors such as the degradability.....»»
The dark side of the American lawn
The American residential lawn is, for many, an iconic landscape and about half of homeowners in the U.S. use fertilizer to keep their yards green and lush. Some proportion of the nitrogen in this fertilizer enters the broader environment, with negati.....»»
Management zone maps of little use to corn growers, study finds
A multiyear analysis tested whether management zone maps based on soil conditions, topography or other landscape features can reliably predict which parts of a cornfield will respond best to higher rates of seeding or nitrogen application. The study.....»»
Nitrogen enrichment delays the emergence of an aridity-induced threshold for plant biomass
Crossing certain aridity thresholds in global drylands can lead to abrupt decays of ecosystem attributes such as plant productivity, potentially causing land degradation and desertification. It is largely unknown, however, whether these thresholds ca.....»»
Exploring the genetic potential of eggplant"s wild relatives for sustainable agriculture
In the pursuit of sustainable agriculture, enhancing nitrogen use efficiency (NUE) in crops stands as a primary objective. With the prolific use of nitrogen (N) fertilizers since the 20th century, agricultural productivity has seen remarkable growth......»»
Organic nitrogen aerosol is an important contributor to global atmospheric nitrogen deposition, finds study
New research emphasizes the previously underestimated significance of atmospheric ON aerosol depositions on ecosystems. Additionally, the ecological effects of ON aerosol depositions are anticipated to increase due to global warming and the decrease.....»»
State of the world"s orchids revealed in new report
