Examining the intricacies of the nitrogen cycle
Nitrogen may not get the same level of attention as its neighbors on the periodic table, carbon and oxygen. But like its neighbors, it's an element we can't live without......»»
Retracing walrus ivory trade of Viking Age reveals early interactions between Europeans and Indigenous North Americans
By examining ancient walrus DNA, an international research team led by Lund University in Sweden have retraced the walrus ivory trade routes of the Viking Age. They found that Norse Vikings and Arctic Indigenous peoples were probably meeting and trad.....»»
Strengthening family supports would boost Nebraska economy, review shows
After examining local, state and national databases, University of Nebraska–Lincoln researchers have concluded that expanding and enhancing supports for Nebraska's families is vital to ensure the "good life" for all Nebraska residents......»»
Enhanced denitrification achieved with innovative biochar-based substrate under low carbon/nitrogen conditions
An study led by researchers from the Harbin Institute of Technology has unveiled a substantial development in wastewater treatment technology. Published in Engineering, the research introduces an innovative approach to improving denitrification in co.....»»
High-energy-density cubic gauche nitrogen successfully synthesized at atmospheric pressure
A research group led by Prof. Wang Xianlong from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences, has successfully synthesized high-energy-density materials cubic gauche nitrogen (cg-N) at atmospheric pressure by treating.....»»
Water flux recovers asynchronously after snow damage in subtropical forest, study shows
Forests play a crucial role in the global water cycle. However, only a few studies have investigated post-damage radiative forcing of evapotranspiration and its underlying processes in forests......»»
Presence of bacteria in soil makes flowers more attractive to pollinators, study shows
Bacteria that live in soil and help roots fix nitrogen can boost certain plants' capacity to reproduce, according to an article published in the American Journal of Botany describing a study of this mechanism in Chamaecrista latistipula, a legume bel.....»»
Injecting manure into growing cover crops can cut pollution, support corn crops
Nitrogen in the soil, where plants can readily utilize it, benefits crop growth and health. However, nitrogen leaving the soil—whether through leaching into the groundwater table, flowing with surface runoff into streams or escaping into the air as.....»»
Climate-smart grazing: Study shows how weather mitigates nitrogen runoff
Livestock production is an important component of U.S. agriculture, with global demand for meat and dairy expected to double in the coming decades. This increase will lead to intensified grazing on U.S. grasslands, potentially exacerbating water qual.....»»
High-resolution images of the sun show how flares impact the solar atmosphere
Solar flares are a fascinating thing and have a profound effect on what astronomers refer to as "space weather." These events vary with the sun's 11-year solar cycle, releasing immense amounts of radiation across the electromagnetic spectrum (from ex.....»»
A record of the Earth’s temperature covering half a billion years

iOS 18 is out, iPhone 16 and Apple Watch Series 10 reviewed
iOS 18, macOS Sequoia, watchOS 11 and tvOS 18 are finally out for public consumption. Benjamin and Chance go through some of their favorite features from this OS cycle, and initial impressions on how the changes are being received. Plus, they react t.....»»
Researchers identify novel approach to minimize nitrogen loss in crops
While agriculture producers apply nitrogen fertilizer to supply nutrients to their crops, they can't always keep those nutrients in the soil for maximum efficiency, often losing them into the atmosphere or water supply as nitrates and nitrous oxide......»»
The legacy of corn nitrogen fertilizer: Study shows lengthy impact in tile drained systems
Midwestern soils are among the most productive in the world, thanks in part to extensive tile drainage systems that remove excess water from crop fields. But water isn't the only thing flowing through tile drains. Nitrogen moves along with soil water.....»»
Biogeochemistry scientists from around the world publish position paper on tackling "hidden" phosphorus
As the world tries to mitigate agriculture's effect on the environment, much of the story can be found in soil, which stores and cycles nutrient elements of carbon, nitrogen, and phosphorus......»»
Examining rare earth metal volatility on the London Stock Exchange
Research in the International Journal of Global Energy Issues has looked at the volatility of rare earth metals traded on the London Stock Exchange. The work used an advanced statistical model known as gjrGARCH(1,1) to follow and predict market turbu.....»»
Shallow waters make the best carbon sinks, researchers find
Marine phytoplankton take up atmospheric carbon and carry it to the seafloor when they die and sink (a process known as organic carbon sedimentation). This biological carbon pump is a powerful part of Earth's carbon cycle, yet scientists don't have a.....»»
Research team achieves high-resolution 2D imaging for graphene devices under high pressure
A research team led by Prof Zhang Zengming from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) has combined nitrogen-vacancy (NV) centers in diamond with a diamond anvil cell (DAC) to achieve non-inv.....»»
Examining climate justice in urban public space adaptation
Evaluating processes and outcomes of climate change adaptation enables learning to facilitate climate-resilient pathways and prevent potentially unjust outcomes. A new study by Vanesa Castán Broto and her colleagues focuses on adaptation interventio.....»»
How plant coverage is affecting the Arctic carbon cycle
Researchers at Columbia University's Department of Earth and Environment Science have discovered new implications for the Arctic carbon cycle in the face of climate change. Their paper, published in Communications Biology, shows how differing plant c.....»»
