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......»»
Saving humanity: Here"s a radical approach to building a sustainable and just society
Collectively, we are driving Earth and civilization towards collapse. Human activities have exceeded planetary boundaries. We are changing the climate, losing biodiversity, degrading land, contaminating freshwater, and damaging the nitrogen and phosp.....»»
Study reveals gut microbiota can ferment carbon nanomaterials into organic metabolites
Recently, a research team led by Prof. Chen Chunying from the National Center for Nanoscience and Technology (NCNST) of the Chinese Academy of Sciences (CAS) revealed that gut microbiota can ferment exogenous carbon nanomaterials (CNMs) as carbon sou.....»»
Average annual net carbon sink of Gracilaria cultivation in China from 2021 to 2030 may double last decade"s
A marine research team led by Professor Yan Qingyun has proposed a method to assess the net carbon sink of marine macroalgae (Gracilaria) cultivation. Then, they calculated the net carbon sink of Gracilaria cultivation in China based on the yield of.....»»
Loose lips sink ships: Project Titan(ic) engineer charged by DOJ for stealing Apple’s self-driving car tech
The United States Department of Justice has announced formal charges against a former Apple engineer. As reported by CNBC, Weibao Wang has been accused of stealing Apple’s autonomous driving technology for a Chinese self-driving car startup. Wang.....»»
Poor soils lose carbon regardless of crop residue and nitrogen inputs, shows study
Let's say you're a corn grower farming on low-fertility soil. How do you go about making that soil healthier and more fertile? Many farmers think if they add plenty of nitrogen fertilizer, that nutrient, along with carbon, will be stored in the soil.....»»
How a sea anemone uses its algal symbionts to assimilate nitrogen in nutrient-poor waters
Tropical oceans are typically nutrient-poor, yet they host vast biologically diverse reef ecosystems built by symbiotic cnidarians (including corals and anemones). This apparent contradiction, known as the Darwin Paradox, has puzzled scientists since.....»»
The far north is burning—and turning up the heat on the planet
The Arctic and surroundings are being transformed from carbon sink to carbon emitter. Enlarge / Fire-damaged trees in a boreal forest near the Saskatchewan River in Alberta, Canada. As northern forests burn, they're releasing m.....»»
The Far North Is Burning—and Turning Up the Heat on the Planet
Wildfires and human meddling are transforming the Arctic and its surroundings from a carbon sink into a carbon emitter, exacerbating the climate crisis......»»
Nitrogen addition and mowing alter drought resistance and recovery of grassland communities
The effects of increased nitrogen input and mowing on the resistance and recovery of temperate grassland experiencing a three-year natural drought (from 2015 to 2017) were investigated based on a five-year field manipulative experiment......»»
Lickable toads and magic mushrooms: Wildlife traded on the dark web is the kind that gets you high
The internet has made it easier for people to buy and sell a huge variety of wildlife—from orchids, cacti and fungi to thousands of birds, mammals, reptiles, amphibians and fish, as well as insects, corals and other invertebrates......»»
Carbon sink models need nitrogen, says study
Nitrogen is necessary when predicting how land plants will take up atmospheric carbon. That's because nitrogen's future trajectory will diverge from that of other factors of plant growth in the coming decades, according to a new study......»»
Nitrogen found to affect soil invertebrates and insects
Higher levels of nitrogen in the environment (coming from fertilizers and livestock, for example) not only affect plants but also soil invertebrates and insects. The diversity of roundworms declines in areas with high input of nitrogen, and numbers o.....»»
Creating universal critical nitrogen dilution curves for Japonica rice
Rice, a staple crop, is widely cultivated in China. The farmers enhance the rice yield and grain quality through nitrogen (N) fertilizers. But using them in excess negatively affects crop production and harms the environment. Therefore, determining t.....»»
Aerial root mucilage fixes atmospheric nitrogen to support plant growth
Plant-associated microbes play an important role in host nutrient utilization, stress tolerance, plant health, and adaptation. Identifying the key mucilage compound and friendly microbe, as well as their protective association with diazotrophic micro.....»»
New method for making ammonia could take a bite out of global energy use
Stanford researchers have discovered a simple and environmentally sound way to make ammonia with tiny droplets of water and nitrogen from the air......»»
Winter cover crops could reduce nitrogen in Illinois drainage water by 30%
As Corn Belt states seek ways to curb nitrogen flow from farms into the Gulf of Mexico, new University of Illinois research adds evidence for winter cover crops as an important part of the solution. A simulation study published in Science of the Tot.....»»
Beaver ponds with deeper sediments store more nitrogen, simple mapping reveals
Beaver ponds contain nitrogen, an essential nutrient that can become a pollutant when too much is present. Land managers need to know if beaver ponds are storing or releasing nitrogen, but chemical testing can be expensive. A new study shows how simp.....»»
Scientists trying to determine what will happen to massive carbon stores as rainforests dry out
Tropical rainforests store 25%-40% of global soil carbon, though they occupy only 7% of Earth's land area. By functioning as a carbon sink, tropical forests prevent more severe effects from climate change......»»
The hidden culprit behind nitrogen dioxide emissions
Nitrogen dioxide is one of the criteria air pollutants that plays an important role as a precursor gas of fine particulate matter and ozone. NO2 emissions are known to be primarily generated by industrial facilities or vehicle exhausts. Recently, a r.....»»
Biden is set to propose toughest-ever rules on car pollution to spur EVs
The proposed standards on cars and light trucks are expected to govern tailpipe emissions of carbon dioxide, smog-forming nitrogen oxide and other pollution from vehicles manufactured for model years 2027 through 2032. .....»»
