Phys.org / Researchers synthesize photosynthetic molecule found in bacteria
Researchers from North Carolina State University have successfully synthesized bacteriochlorophyll a, which is a photosynthetic pigment found in bacteria that absorbs infrared light. The work represents the first chemical ...
Phys.org / Quantum simulations reveal spin transport in 1D materials
Researchers from the Department of Energy's Quantum Science Center (QSC) headquartered at Oak Ridge National Laboratory (ORNL) have achieved a significant milestone by demonstrating the first digital quantum simulations of ...
Phys.org / Bolivian mummy rewrites scarlet fever's past, suggesting killer bacterium circulated centuries before colonization
Researchers have identified the genetic material of scarlet fever while examining a tooth from a naturally mummified skull housed at MUNARQ, the National Museum of Archaeology in La Paz. Using a method that reassembled previously ...
Phys.org / As polar ice changes, so do the rules governing it
Sea ice is not just solid frozen water. It's riddled with tiny pockets and channels of liquid brine. Whether those pockets connect to form pathways determines whether seawater, nutrients and gases can move through the ice, ...
Phys.org / Pill bugs don't just use the minerals they eat—they rebuild them inside their bodies
Placing small stones in a bug cage is beneficial when raising pill bugs, a type of woodlouse. Researchers at the University of Tsukuba have discovered that pill bugs do not directly incorporate ingested calcium carbonate ...
Phys.org / 'Safe' fertilizer linked to extreme water quality loss in Canadian Prairies
Research published in Nature Water found that widespread application of the common farm fertilizer, urea, severely degrades water quality in the Canadian Prairies. Researchers at the University of Manitoba and the University ...
Phys.org / Machine learning tool pinpoints optimal locations for tree planting, offering a powerful tool for climate mitigation
Afforestation—establishing forests on previously non-forested land, or where forests have not existed for a long time—is one of the nature-based and cost-effective solutions for climate change mitigation because it offsets ...
Phys.org / Emerging in Alaska, dominant H5N1 strain spread continent-wide through migratory birds
An international group of scientists mapped the spread of the current dominant strain of highly pathogenic avian influenza virus through North American bird populations in 2024. Led by scientists from St. Jude Children's ...
Phys.org / Multitasking quantum sensors can measure several properties at once
A special class of sensors leverages quantum properties to measure tiny signals at levels that would be impossible using classical sensors alone. Such quantum sensors are currently being used to study the inner workings of ...
Phys.org / Marine sponge bacterium enzyme reveals a two-part route to make terpenoids
The molecular structure of an enzyme from a marine bacterium with potential industrial uses has been determined by RIKEN researchers. The insights they have gained could help make a range of useful compounds through genetic ...
Phys.org / Ancient seabird guano reveals how climate change may shape future populations
By analyzing peat cores, researchers have shown how populations of nesting seabirds have fluctuated on a sub-Antarctic island over 8,000 years. They found that bird numbers rose and fell alongside shifts in climate, offering ...
Phys.org / Drought takes a heavy toll on bumblebees
Drought significantly reduces the reproductive success of bumblebee colonies, according to a new study conducted by a research team at the University of Würzburg and published in the Proceedings of the Royal Society B: Biological ...
