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......»»
Scientists find the sounds beneath our feet are fingerprints of rock stability
If you could sink through the Earth's crust, you might hear, with a carefully tuned ear, a cacophany of booms and crackles along the way. The fissures, pores, and defects running through rocks are like strings that resonate when pressed and stressed......»»
Discovery of invisible nutrient discharge on Great Barrier Reef raises concerns
Scientists using natural tracers off Queensland's coast have discovered the source of previously unquantified nitrogen and phosphorous that are having a profound environmental impact on the Great Barrier Reef......»»
New research finds that ancient carbon in rocks releases as much carbon dioxide as the world"s volcanoes
A new study led by the University of Oxford has overturned the view that natural rock weathering acts as a CO2 sink, indicating instead that this can also act as a large CO2 source, rivaling that of volcanoes. The results, published today in the jour.....»»
Gain-of-function allele of HPY1 coordinates source and sink to increase grain yield in rice
Rice is a primary staple crop for over half of the global population, and the continual enhancement of its yield holds significant significance in ensuring world food security. Therefore, achieving sustained increases in rice production has remained.....»»
Study sheds light on differentiated nitrogen sources of co-occurring epiphytes in Chinese subtropical forests
Epiphytes, including lichens, bryophytes, ferns and spermatophytes, are a large and widely distributed group across many forest ecosystems. Acquiring enough nitrogen (N) to support their life processes in nutrient-poor canopies is a crucial challenge.....»»
Soil carbon, nitrogen, soil fertility and climate change are tightly linked, new research shows
In a first-of-its-kind long-term study, a collaborative group of scientists, including senior author Ashley Keiser, assistant professor of soil ecology at the University Of Massachusetts Amherst's Stockbridge School of Agriculture, have discovered th.....»»
From seafloor to space: New bacterial proteins shine light on climate and astrobiology
Gigatons of greenhouse gas are trapped under the seafloor, and that's a good thing. Around the coasts of the continents, where slopes sink down into the sea, tiny cages of ice trap methane gas, preventing it from escaping and bubbling up into the atm.....»»
Genetically engineering associations between plants and diazotrophs could lessen dependence on synthetic fertilizer
Nitrogen is an essential nutrient for plant growth, but the overuse of synthetic nitrogen fertilizers in agriculture is not sustainable......»»
Tuvalu will always be a state, even if underwater, says PM
Tuvalu could be one of the first nations to sink beneath the sea as a result of climate change, but that doesn't mean its statehood is up for discussion, the tiny Pacific archipelago's prime minister said Thursday......»»
Chicago"s West Side is an air pollution hotspot, new study finds
The western edge of Chicago—including the North and South Lawndale, East Garfield Park, Archer Heights and Brighton Park neighborhoods—experiences up to 32% higher concentrations of nitrogen dioxide (NO2) air pollution compared to the rest of the.....»»
Ultrathin films achieve record hydrogen-nitrogen separation
Metal-organic frameworks (MOFs) are a class of materials that contain nano-sized pores. These pores give MOFs record-breaking internal surface areas, which make them extremely versatile for a number of applications: separating petrochemicals and gase.....»»
"Crappier-than-crap" molecule exposed in overhaul of carbon-nitrogen-hydrogen chemistry
Russian researchers have explained why scientists studying crude oil and celestial chemistry—as well as certain down-to-earth matters—frequently come across some molecules incorporating carbon, nitrogen, and hydrogen but not other combinations of.....»»
Autopsy of a star reveals what was eviscerated by a monster black hole
From the interior of a star to the accretion disk of a black hole. Enlarge / Ions of nitrogen and carbon show up in the spectrum of X-rays from a black hole's accretion disk. (credit: NASA/Chandra) Even huge stars are no.....»»

Satellite data show wildfire, soil emissions likely increasing air pollution in remote forests
Satellite data from across California's landscapes reveal an increase in nitrogen dioxide levels in remote forest areas, and wildfire and soil emissions are likely the reasons why, according to a paper from University of California, Davis, published.....»»
Fungi-eating plants and flies team up for reproduction
Fungi-eating orchids were found for the first time to offer their flowers to fungi-eating fruit flies in exchange for pollination, which is the first evidence for nursery pollination in orchids. This unique new plant-animal relationship hints at an e.....»»
Heat sensor protects the Venus flytrap from fire
The Venus flytrap can survive in the nutrient-poor swamps of North and South Carolina because it compensates for the lack of nitrogen, phosphate and minerals by catching and eating insects. It hunts with snap traps that have sensory hairs on them. If.....»»
