Phys.org / Long-term observations of marine clouds reveal how in-cloud motions shape rain
Research led by atmospheric scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory sheds new light on one of the fundamental challenges of weather forecasting: determining the conditions under ...
Phys.org / Molecular dinitrogen anions pave the way for low-temperature ammonia synthesis
While ammonia (NH₃) is best known for its role in fertilizer production, it is attracting attention as a carbon-free hydrogen carrier, potentially offering a practical way to store and transport clean fuel. Despite this promise, ...
Phys.org / Pearls and bird feathers inspire simpler method for producing structural colors
Colors in nature are not always produced by pigments. Pearls, bird feathers, butterfly wings and opals display brilliant colors through the interaction of light with microscopic structures, a phenomenon known as structural ...
Phys.org / A new way to make better use of ruthenium in single-atom catalysts
Ruthenium (Ru) is a valuable metal used in catalysts to speed up chemical reactions in many industrial processes. It can help improve efficiency and reduce the energy needed for chemical production. However, because it is ...
Phys.org / Breaking the ice: Scientists use attracting particles to form an anti-spin ice
In a recent Nature Communications study, researchers have reported the realization of an anti-spin ice, a system that does the opposite of conventional spin ices by breaking the ice rule that governs them.
Phys.org / Heavy hydrogen in 3I/ATLAS's methane points to a frigid birthplace
The interstellar comet 3I/ATLAS carries a chemical clue to conditions in the planetary system of its origin, locked away long before it reached our sun. Its methane signature is unusually rich in heavy hydrogen, suggesting ...
Phys.org / Collective human metabolism produces 2 billion metric tons of CO₂ a year, global study estimates
A University of Bath–led study has estimated that the carbon dioxide produced by humans as our bodies turn food into energy rose by 74% between 1985 and 2015, reaching 2.05 billion metric tons a year. Researchers say the ...
Phys.org / Mars dust may be less abrasive than lunar dust, spacesuit samples suggest
Tucked away among its sensors, cameras and navigation tools, NASA's Mars rover Perseverance is wearing small swatches of spacesuit material. A rover doesn't need a spacesuit, but the swatches—each less than a square inch ...
Phys.org / 2,700-year-old mummy head yields first molecular evidence linking aloe to Egyptian embalming
What materials did ancient Egyptians use to preserve the dead, and how can their composition still be investigated thousands of years later? An interdisciplinary team at Marburg University has combined modern natural product ...
Phys.org / Why some trees thrive far from home—and what that means for carbon sinks
In a study spanning 192 sites and four continents, researchers have discovered that conifers planted in the Southern Hemisphere grow up to four times faster and are more drought-resistant than those growing in their native ...
Phys.org / Rare Iron Age Celtic helmet discovered in northeastern Poland far from its homeland
Around 2,400 years ago, at Łysa Góra in Poland, a group of people took a bronze helmet, crushed it, broke it into pieces and threw it into a pit with iron adzes and a scythe. Such helmets are sometimes found in lavish graves ...
Phys.org / Four superconducting cables link two large quantum processors into one
As quantum computers grow more ambitious, many researchers believe the best way forward is to build them in multiple interconnected parts. In these modular designs, separate quantum processors are linked so they can work ...
