The neutrino image suggests that cosmic ray interactions are more intense in the center of our galaxy than once thought . The results are published in an article in the journal Science For ages , the view of our Milky Way galaxy has inspired awe , visible with the naked eye as a hazy band of stars that stretches across the sky . Now IceCube researchers are able to see the Milky Way using neutrinos â tiny , ghostlike

A new computer simulation of domestic catsâ noses suggests that the convoluted nasal structures involved in their sense of smell function similarly to parallel coiled gas chromatographsâlaboratory equipment used for highly efficient analysis of the chemical makeup of substances . Zhenxing Wu of the Ohio State University , U.S . and colleagues present these findings in the open-access journal PLOS Computational Biology  on June 29, 2023. Vertebrates use their

Plasmoids are also associated with the sudden brightening of the aurora . The space physics research group at the University of Helsinki

They found that the air separates into two flow streams , one that is cleansed and humidified and another delivering the odorant quickly and efficiently to the system responsible for
