Warming temperatures are causing a vicious cycle of increased carbon dioxide release in alpine environments. Because temperatures are getting warmer, lowland plants are encroaching on alpine environments. While more plants are sucking in carbon dioxide, it also means more carbon dioxide is released from the soil. Soil microbes release carbon from the alpine soil when they grow, and they’re growing a lot faster in the presence of lowland plants. More CO2 released into the atmosphere makes temperatures warmer, causing lowland plants to climb up higher and stimulate CO2 release. Read full article here

‘Ghostly’ neutrinos provide new path to study protons
In groundbreaking research, an international collaboration of scientists from the University of Rochester have used a beam of neutrinos to measure the size and shape of the protons that make up the nuclei of atoms. This feat, once thought impossible, provides scientists with a new way of looking at the small components of an atom’s nucleus and opens up a wealth of new information about the structure of an atom’s nucleus and the dynamics of the forces that affect neutrino interactions. The researchers solved the challenge of harnessing neutrinos in large numbers by using a neutrino detector containing a target of both hydrogen and carbon atoms, and over nine years of data collection at Fermilab’s accelerator.
