Quarks are distributed differently in free protons and neutrons versus those inside nuclei, something called “the EMC effect.” Scientists previously thought that the EMC effect treated the up and down quarks in protons and neutrons equally. New high-precision data from the MARATHON experiment indicates that the EMC effect may exert more influence on the distribution of down quarks compared to up quarks inside nuclei.

Scientists measure how unpaired electrons in atoms at one end of a molecule can drive chemical reactivity on the molecule's opposite side. This work shows how molecules containing these so-called free radicals could be used in a whole new class of reactions.

As precipitation patterns shift in response to climate change, scientists must understand how this change affects soil viruses. In this study, scientists analyzed DNA viruses in three grassland soils with different historical precipitation patterns: low precipitation from eastern Washington, intermediate precipitation from Kansas, and high precipitation from Iowa. The researchers found that viruses were more diverse and more common in drier soil.

Although blockchain is best known for securing digital currency payments, researchers at the Department of Energy’s Oak Ridge National Laboratory are using it to track a different kind of exchange: It’s the first time blockchain has ever been used to validate communication among devices on the electric grid.

Researchers say that the Chilean Andes could face marked snow loss and roughly 10% less mountain water runoff with a global warming of approximately 2.5 degrees Celsius over the next 30 years. The study has implications for the California Sierra Nevada and highlights the need for carbon mitigation.
