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......»»
Towards synthesis of phenanthridine-based pharmaceutical compounds
Phenanthridines are heterocyclic compounds consisting of two six-membered benzene rings fused to a six-membered ring containing nitrogen. They are found in many naturally occurring organic compounds known for their anticancer and antitumor properties.....»»
Sinking seamount offers clues to slow motion earthquakes
Scientists have long puzzled over what happens when seamounts—mountains and volcanoes on the seafloor—are pulled into subduction zones. Now, new research from The University of Texas at Austin shows that when seamounts sink, they leave behind a t.....»»
Novel protocol helps to quantify catchment-scale nitrate yield and fluvial export dynamics
Anthropogenic production of reactive nitrogen (N) is increasing rapidly due to the growing demand for food production. Rivers are the receptors of N, especially nitrate (NO3–), produced in their drainage catchments, therefore, quantifying catchment.....»»
Researchers reveal mechanism of SnO2 electron transport layer modified by graphdiyne in perovskite solar cells
Prof. Sun Baoyun's group from the Institute of High Energy Physics (IHEP) of the Chinese Academy of Sciences recently used graphdiyne oxide (GDYO), fluorinated GDYO (FGDYO) and nitrogen-doped GDYO (NGDYO) to improve the SnO2 electron transport layer.....»»
Single-atom vacancies in atomically thin insulators created in ultra-high vacuum
Single photons have applications in quantum computation, information networks, and sensors, and these can be emitted by defects in the atomically thin insulator hexagonal boron nitride (hBN). Missing nitrogen atoms have been suggested to be the atomi.....»»
Scientists explain why peanuts "dance" when dropped in beer
When peanuts are dropped into a pint of beer, they initially sink to the bottom before floating up and "dancing" in the glass......»»
Twitter’s new CEO wants to turn it into the ‘world’s most accurate real-time information source’
Linda Yaccarino is busting through the doors of Twitter — not with a sink — but with a letter. The pen is mightier than the … The post Twitter’s new CEO wants to turn it into the ‘world’s most accurate real-time information so.....»»
Effect of nitrogen deposition on animal species stronger than expected
Anthropogenic increased nitrogen deposition is a well-known environmental stressor, resulting in impoverishment of soil quality in naturally nutrient-poor ecosystems. As a result, habitat conditions for plant and animal species are also changing. Suc.....»»
Study finds different nitrogen saturation thresholds in a temperate steppe
Nitrogen saturation refers to the phenomenon that the net primary productivity of an ecosystem—a fundamental ecosystem function and also a measure of carbon (and energy) sequestration by the ecosystem—tends to initially increase with increasing n.....»»
How long is Diablo 4?
Whether you're just looking to go through the main storyline or dive into some end-game content, here's how many hours you could expect to sink into Diablo 4......»»
How Sierra Nevada snowpack confounds Central Valley groundwater readings
Billions of tons of snow piled atop the Sierra Nevada Mountains can cause parts of the Central Valley, just west of the range, to sink—muddling groundwater assessments that take sinking as a sign of depleted aquifers. A recent Stanford University s.....»»
Treated wastewater in Victoria is still contaminated, study finds. So are people and the environment safe?
Wastewater is a byproduct of humanity produced all day, every day. At home, wastewater is the used water that disappears when you flush the toilet, empty the sink or drain the washing machine......»»
Carbon-based stimuli-responsive nanomaterials: Their classification and application
Carbon-based stimuli-responsive nanomaterials are gaining much attention due to their versatility, including disease diagnosis and treatment. They work under endogenous (pH, temperature, enzyme, and redox) or exogenous (temperature, light, magnetic f.....»»

Machine learning-based protein annotation tool predicts protein function
Microbes drive key processes of life on Earth. They affect global elemental cycles—the movement of carbon, nitrogen, and other elements. They also promote plant growth and affect the development of diseases. These roles are essential in every ecosy.....»»
How much nitrogen does corn get from fertilizer? Less than farmers think
Corn growers seeking to increase the amount of nitrogen taken up by their crop can adjust many aspects of fertilizer application, but recent studies from the University of Illinois Urbana-Champaign show those tweaks don't do much to improve uptake ef.....»»
Antarctic alarm bells: Observations reveal deep ocean currents are slowing earlier than predicted
Antarctica sets the stage for the world's greatest waterfall. The action takes place beneath the surface of the ocean. Here, trillions of tons of cold, dense, oxygen-rich water cascade off the continental shelf and sink to great depths. This Antarcti.....»»
From mangroves to fjords, coastal ecosystems can take up or emit greenhouse gases. But globally, they"re a vital sink
Coastal ecosystems can absorb or emit the three main greenhouse gases: carbon dioxide, methane and nitrous oxide......»»

Orchids" ability to grow on other plants independently evolved multiple times
The most extensive study of the genetic relationships among orchids to date reveals that the flower's ability to grow on other plants evolved independently multiple times. A team of researchers, led by Penn State biologists, compared the sequences of.....»»
