(Phys.org) —Astrophysicists Dan Hooper and Tracy Slatyer of Fermi National Accelerator Laboratory, and Princeton University respectively, have written a paper—and uploaded it to the preprint server arXiv—in which they ...
(Phys.org)—A large multinational team of researchers, led by Markku Kulmala of Finland's University of Helsinki, has for the first time discovered the birth process of a class of aerosols. As they describe in their paper ...
(Phys.org)—This morning CERN completed the first LHC proton run. The remarkable first three-year run of the world's most powerful particle accelerator was crowned by a new performance milestone. The space between proton ...
