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.....»»
Did some of Earth"s water come from the solar wind?
The source of Earth's water is an enduring mystery that extends to exoplanets and the notion of habitability. In broad terms, Earth's water was either part of the planet from the beginning of its formation in the solar nebula or delivered later, mayb.....»»

What do planet formation and badminton have in common?
Dust grains in protoplanetary disks align via the same aerodynamics as the sport. The birth of a planet starts with a microscopic grain floating in a protoplanetary disk, a swirli.....»»
New venomous reptile species from the Late Triassic unearthed in Arizona
A new species of small, venomous reptile, Microzemiotes sonselaensis, has been discovered in the Late Triassic Chinle Formation in northeastern Arizona. The findings, recently published in PeerJ, shed new light on the evolution of venomous feeding st.....»»
Microtubule formation mechanism sheds light on how cells build their internal skeleton
Inside every cell, a network of tiny filaments, called the microtubule cytoskeleton, helps maintain the cell's shape, allows it to divide, and transports vital materials from one part of the cell to another. The filaments that form this network, term.....»»
Is the physics of red blood cells in bats a key to "artificial hibernation" for humans?
The mechanical properties of red blood cells (erythrocytes) at various temperatures could play an important role in mammals' ability to hibernate. This is the outcome of a study that compared the thermomechanical properties of erythrocytes in two spe.....»»
El Niño Southern Oscillation caused spike in 2023 temperatures, study finds
A study by scientists at the University of Miami Rosenstiel School of Marine, Atmospheric, and Earth Science identified El Niño–Southern Oscillation as the primary cause of the spike in global surface temperature in 2023, not human-induced climate.....»»
Ammonia fuel cells see performance gains with new catalyst layer
The pursuit of clean and efficient energy conversion technologies has led to significant advancements in fuel cell research. A study conducted at Fuzhou University and published in Frontiers in Energy, presents a novel approach to enhance the perform.....»»
Climate change can alter methane emission and uptake in the Amazon
Extreme temperatures and humidity levels (excessive rain or drought) projected for the Amazon in the context of climate change may increase the volume of methane-producing microorganisms in flooded areas and reduce potential uptake of this greenhouse.....»»
Rapid analysis finds climate change’s fingerprint on Hurricane Helene
1.3° C of warming means rainfall like this may now be expected every 70 years. Hurricane Helene crossed the Gulf of Mexico at a time when sea surface temperatures were at rec.....»»
New insights into bubble interference could enhance electrode design
Industrial electrochemical processes that use electrodes to produce fuels and chemical products are hampered by the formation of bubbles that block parts of the electrode surface, reducing the area available for the active reaction. Such blockage red.....»»
The GALAH fourth data release provides vital data on one million stars in the Milky Way
For the past 10 years, Australia's ARC Center of Excellence in All Sky Astrophysics in 3 Dimensions (ASTRO 3D) has been investigating star formation, chemical enrichment, migration, and mergers in the Milky Way with the Anglo-Australian Telescope (AA.....»»
Report on global water resources: Conditions in 2023 were either too dry or too wet
Not only was 2023 characterized by unprecedentedly high temperatures but also by excessive droughts in many parts of the world as well as floods in other areas. The World Meteorological Organization (WMO) has now presented its third report on the sta.....»»
How future heat waves at sea could devastate UK marine ecosystems and fisheries
The oceans are warming at an alarming rate. 2023 shattered records across the world's oceans, and was the first time that ocean temperatures exceeded 1°C over pre-industrial levels. This led to the emergence of a series of marine heat wave events ac.....»»
Miami-Dade study questions reliability of land surface temperature for heat risk assessment
A study published in the journal PLOS Climate on October 2, 2024, examines the effectiveness of using land surface temperatures (LSTs) as proxies for surface air temperatures (SATs) in subtropical, seasonally wet regions......»»
Climate change is causing algal blooms in Lake Superior for the first time in history
Lake Superior is known for its pristine waters, but a combination of nutrient additions from increasing human activity (including farming and development), warming temperatures and stormy conditions have resulted in more frequent blooms of potentiall.....»»
Geological surveys shed light on the formation mystery of Uruguay"s amethyst geodes
Amethyst is a violet variety of quartz that has been used as a gemstone for many centuries and is a key economic resource in northern Uruguay. Geodes are hollow rock formations often with quartz crystals, such as amethyst, inside......»»
As temperatures rise, researchers identify mechanisms behind plant response to warming
Microscopic pores on the surface of leaves called stomata help plants "breathe" by controlling how much water they lose due to evaporation. These stomatal pores also enable and control carbon dioxide intake for photosynthesis and growth......»»
Report: Global drought threatens food supplies and energy production
In July 2024, global temperatures reached unprecedented levels, breaking historical records with an average of 17.16°C. This extreme heat has led soil water to evaporate, leaving the vegetation and biodiversity more fragile and under stress in many.....»»
Armyworms are invading North Texas: What are they?
They slither across lawns and pastures in a sort of formation, chewing grass, plants and even weeds. Only an inch or inch-and-a-half long, the caterpillars do not look particularly destructive......»»
