Unraveling differences in temperature sensitivity of soil organic matter decomposition under various oxygen conditions
Soil organic matter (SOM) decomposition is a key process that affects soil carbon storage and greenhouse gas emissions. Investigating the temperature sensitivity (Q10) of SOM decomposition and its regulating mechanisms is important for improving pred.....»»
Researchers discover previously unknown gene that indirectly promotes photosynthesis in blue-green algae
Cyanobacteria—also called blue-green algae—are known as the "plants of the ocean" because they carry out photosynthesis on a gigantic scale, produce oxygen and extract the greenhouse gas CO2 from the environment. However, to do this they need add.....»»
Study shedding new light on Earth"s global carbon cycle could help assess liveability of other planets
Research has uncovered important new insights into the evolution of oxygen, carbon, and other vital elements over the entire history of Earth—and it could help assess which other planets can develop life, ranging from plants to animals and humans......»»
Measuring the atmospheres of other worlds to see if there are enough nutrients for life
Life on Earth depends on six critical elements: carbon, hydrogen, nitrogen, oxygen, phosphorous, and sulfur. These elements are referred to as CHNOPS, and along with several trace micronutrients and liquid water, they're what life needs......»»
Innovative sensing platform unlocks ultrahigh sensitivity in conventional sensors
Optical sensors serve as the backbone of numerous scientific and technological endeavors, from detecting gravitational waves to imaging biological tissues for medical diagnostics. These sensors use light to detect changes in the properties of the env.....»»
New method reveals hidden activity of life below ground
A team of scientists led by researchers at Bigelow Laboratory for Ocean Sciences have developed an innovative method to link the genetics and function of individual microbes living without oxygen deep below Earth's surface. Measuring both of these at.....»»
A chemically bonded photocatalyst with rich oxygen vacancies for improved photocatalytic decontamination
A challenge in promoting the industrial application of photocatalysis technology for environment remediation lies in the design of high-performance photocatalysts. These photocatalysts should be endowed with efficient photo-carrier separation and int.....»»
New satellite dataset sheds light on Earth"s plant growth
Gross Primary Production (GPP), the process through which plants convert carbon dioxide and sunlight into glucose and oxygen, is the Earth's largest carbon flux. Accurate quantification of GPP is crucial for understanding carbon budgets and their imp.....»»
Geometry-adaptive electrocatalysis: Proposed approach could double efficiency of energy conversion technologies
As the world seeks sustainable solutions to meet escalating energy demands, a collaborative team of researchers from the Universities of Tartu and Copenhagen has proposed an innovative approach to overcome long-standing limitations in oxygen electroc.....»»
Additional nutrients intensify dead zones in oceans, researchers find
As more and more nutrients from land and air enter the world's oceans, the dead zones without oxygen in the water will increase in size and intensity. That is the warning that Ph.D. student Zoë van Kemenade, an organic geochemist at NIOZ, draws from.....»»
How do halibut migrate? Clues are in their ear bones
Rising temperatures, changes in major currents, oxygen depletion at great depths: the Gulf of St. Lawrence has undergone major changes in its environmental conditions in recent decades. That has put many species in danger and, as a consequence, made.....»»
Research suggests natural electrical grid deep inside Earth enables many types of microbes to survive
To "breathe" in an environment without oxygen, bacteria in the ground beneath our feet depend upon a single family of proteins to transfer excess electrons (produced during the "burning" of nutrients) to electric hairs called nanowires projecting fro.....»»
Hypoxia is widespread and increasing in the ocean off the Pacific Northwest coast, study shows
Low oxygen conditions that pose a significant threat to marine life are widespread and increasing in coastal Pacific Northwest ocean waters as the climate warms, a new study shows......»»
Regulating atomic Fe-Rh site distance for efficient oxygen reduction reaction
In a study published in the journal Science China Chemistry, the authors systematically design and investigate the site-distance effect of Fe-Rh atom catalysts (Fe-Rhx@NC) supported by N-doped graphene for ORR by an integrated theoretical and experim.....»»
Researchers use genetic engineering to create flood-tolerant plants
Adding too much water to your plants can damage them as much as not having enough water. In the environment, plants submerged under excessive rain have limited access to light and oxygen, which reduces or eliminates their ability to thrive. This pose.....»»
