The first measurements of a heavy oxygen isotope in Earth’s upper atmosphere suggest that isotopic concentrations could become powerful probes of atmospheric processes at otherwise hard-to-probe altitudes. Read More »
Using cross-correlation measurements and an updated cosmic-microwave-background lensing map, researchers determine cosmological parameters with greater precision. Read More »
Detecting neutrinoless double-beta decay would confirm that the neutrino is its own antiparticle. Data from the KamLAND-Zen experiment contain no strong evidence of such events, constraining neutrino properties. Read More »
