Catalyzing ammonia formation at lower temperatures with ruthenium
Nitrogen is an essential nutrient for plant growth. While about 80% of earth is nitrogen, it is mostly contained in the atmosphere as gas, and hence, inaccessible to plants. To boost plant growth, especially in agricultural settings, therefore, chemi.....»»
Q&A: What 106°F heat does to plants
With temperatures across much of Southern California crossing triple digits this week, we are relying more than ever on plants to keep us cool outside. But the plants don't get much of a break from the relentless sun......»»
Nuclear fuel experiment demonstrates how liquid plutonium oxide behaves at the hottest temperatures
The 2011 accident at the Fukushima-Daiichi plant in Japan inspired extensive research and analysis that elevated nuclear energy into a standard bearer for safety. It also inspired a number of studies at the U.S. Department of Energy's (DOE) Argonne N.....»»
Dangerous heat wave intensifies in US Southwest
A punishing heat wave gripping California and parts of the southwestern United States was intensifying Thursday as forecasters warned of dangerous temperatures......»»
A space oddity—small exoplanet challenges existing theories on planet formation
A research team led by Lund University in Sweden has discovered a small planet that displays peculiar orbital motion. The shimmying planet, located 455 light-years from Earth, shows that planetary systems can be considerably more complex than researc.....»»
Researchers explore key interaction sites and pathways in ammonia capture
The design and development of high-performance materials are crucial for efficient ammonia capture. Generally, these materials are characterized by abundant ammonia adsorption sites and rapid ammonia transport channels, enabling the effective capture.....»»
Researchers say 40% of UK seabird species are in trouble—bird flu, climate change, overfishing to blame
A visit to a seabird colony in summer is an assault on the senses. First there's the noise, then the overwhelming ammonia smell that stains the memory, and then the swirl of color and activity on the white-washed cliffs......»»
Sunken village emerges as Greek drought bites
Record-breaking temperatures and prolonged drought in Greece have exposed a sunken village in Athens' main reservoir for the first time in 30 years......»»
Gravitational wave observatories could detect primordial black holes speeding through the solar system
Cosmologists have long hypothesized that the conditions of the early universe could have caused the formation of black holes not long after the Big Bang. These "primordial black holes" have a much wider mass range than those that formed in the later.....»»
Copper-based catalyst paves the way for sustainable ammonia production
Ammonia plays a critical role in food production and industrial development, with a global market size of approximately 175 million metric tons and a market value of $67 billion. Likewise, it is a high-energy-density carrier, making it a key player i.....»»
Webb discovers six new "rogue worlds" that provide clues to star formation
Rogue planets, or free-floating planetary-mass objects (FFPMOs), are planet-sized objects that either formed in interstellar space or were part of a planetary system before gravitational perturbations kicked them out......»»
Study reveals distinct roles of H3K27me3 and H3K36me3 in winter wheat vernalization
Vernalization is the phenomenon whereby plants require prolonged exposure to low temperatures to flower. This ensures that overwintering plants undergo reproductive growth under suitable light and temperature conditions, thereby securing yield......»»
Study: Plasmonic copper nanowires boost nitrate reduction efficiency
The electrocatalytic nitrate reduction reaction (NO3RR) has attracted the attention of researchers for its significant value in ammonia synthesis and effluent treatment. Plasmon-assisted electrocatalysis provides a powerful strategy for efficient con.....»»
Hubble traces star formation in nearby nebula NGC 261
NGC 261 blooms a brilliant ruby red against a myriad of stars in this new image from NASA's Hubble Space Telescope. Discovered on Sept. 5, 1826 by Scottish astronomer James Dunlop, this nebula is located in one of the Milky Way's closest galactic com.....»»
What is an Atlantic Niña? How La Niña"s smaller cousin could affect hurricane season
The North Atlantic Ocean has been running a fever for months, with surface temperatures at or near record highs. But cooling along the equator in both the Atlantic and eastern Pacific may finally be starting to bring some relief, particularly for vul.....»»
International report confirms record-high global temperatures in 2023
Greenhouse gas concentrations, the global temperature across land and the ocean, global sea level, and ocean heat content all reached record highs in 2023, according to the 34th annual State of the Climate report......»»
Biomass-based polymer can capture and release CO₂ without high pressure or extreme temperatures
A new, biomass-based material developed by FAMU-FSU College of Engineering researchers can be used to repeatedly capture and release carbon dioxide......»»
New varactor enhances quantum dot device measurements at millikelvin temperatures
The development of quantum computing systems relies on the ability to rapidly and precisely measure these systems' electrical properties, such as their underlying charge and spin states. These measurements are typically collected using radio-frequenc.....»»
Carbon emissions from forest soil will likely grow with rising temperatures
The soils of northern forests are key reservoirs that help keep the carbon dioxide that trees inhale and use for photosynthesis from making it back into the atmosphere. But a unique experiment led by Peter Reich of the University of Michigan is showi.....»»
Scientists propose guidelines for solar geoengineering research
Scientists for several years have studied the theoretical effectiveness of injecting sulfur dioxide into the stratosphere to reflect heat from the sun and offset Earth's warming temperatures. But they also want to ensure that the solar geoengineering.....»»
A small molecular glue that increases P53 level and suppresses tumor growth in vivo
Molecular glues are typically small chemical molecules that act on the interface between the target protein and the degradation machinery to trigger ternary complex formation. Identification of molecular glues is challenging, and there has been a lac.....»»
