Phys.org / Cyanobacteria can utilize toxic guanidine as a nitrogen source
Guanidine is an organic compound primarily used as a denaturing reagent to disrupt the structures of proteins and nucleic acids. Together with partner institutions, scientists at the Helmholtz Centre for Environmental Research ...
Phys.org / Magnetic fields slow carbon migration in iron by altering energy barriers, study shows
Professor Dallas Trinkle and colleagues have provided the first quantitative explanation for how magnetic fields slow carbon atom movement through iron, a phenomenon first observed in the 1970s but never fully understood. ...
Phys.org / Birding enthusiasts can help songbirds avoid Salmonella epidemics
UCLA biologists are developing a tool to predict when deadly Salmonella outbreaks are likely to happen in wild songbird populations so that people can protect their feathered friends by taking down bird feeders at the right ...
Phys.org / New global standard set for testing graphene's single-atom thickness
Graphene could transform everything from electric cars to smartphones, but only if we can guarantee its quality. The University of Manchester has led the world's largest study to set a new global benchmark for testing graphene's ...
Phys.org / Uncovering a hidden mechanism in Met receptor activation
Researchers at the Nano Life Science Institute (WPI-NanoLSI), Kanazawa University, in collaboration with Osaka University and the National Institutes for Quantum Science and Technology, have uncovered a previously unknown ...
Phys.org / Possible Black Death mass grave discovered near Erfurt, Germany
An interdisciplinary research team from Leipzig has discovered strong evidence of a Black Death mass grave near the deserted medieval village of Neuses, outside Erfurt (Germany). It represents the first systematically identified ...
Phys.org / Phages and bacteria accumulate distinctive mutations aboard the International Space Station
In a new study, terrestrial bacteria-infecting viruses were still able to infect their E. coli hosts in near-weightless "microgravity" conditions aboard the International Space Station, but the dynamics of virus-bacteria ...
Phys.org / Webb delivers unprecedented look into heart of Circinus galaxy
The Circinus galaxy, a galaxy about 13 million light-years away, contains an active supermassive black hole that continues to influence its evolution. The largest source of infrared light from the region closest to the black ...
Phys.org / New tool lets anyone audit a country's methane claims
For years, countries have told the United Nations how much methane they emit using a kind of bottom-up bookkeeping: Count the cows and oil barrels, estimate the volume of trash, and multiply by standard emission factors.
Phys.org / Recovering tropical forests grow back nearly twice as fast with nitrogen
Young tropical forests play a crucial role in slowing climate change. Growing trees absorb carbon dioxide from the air, using photosynthesis to build it into their roots, trunks, and branches, where they can store carbon ...
Phys.org / Organisms in the Atacama Desert soil are remarkably diverse, study shows
A new study shows that resilient and remarkably diverse populations of organisms can persist in the soil despite harsh and extremely dry conditions. An international team led by researchers from the University of Cologne, ...
Phys.org / Urban soils get new life by mixing excavated dirt with organic waste
Excavated soil from construction sites usually ends up in landfills, but it has great potential. Researchers at the Technical University of Munich (TUM) show how excavated soil can be enriched with organic waste so that it ...
