Physicists Detect Solar CNO Neutrinos for First Time

Posted on

For most of their existence, stars are fuelled by the fusion of hydrogen into helium. Fusion proceeds via two processes that are well understood theoretically: the proton-proton (p-p) chain and the carbon-nitrogen-oxygen (CNO) cycle. Neutrinos that are emitted along such processes in the solar core are the only direct probe of… […]

Leaf-Cutter Ants Have Biomineral Armor

A team of researchers from the University of Wisconsin-Madison and the Smithsonian Institution has discovered a dense layer of biogenic high-magnesium calcite in the exoskeletons of major workers of the leaf-cutter ant Acromyrmex echinatior; they’ve also found that this armor accumulates rapidly as ant workers mature and that the biomineral layer… […]
