Dear Reader, Check out highlights from today's top stories: An experiment aims to find a new type of neutrino that could be a key to the universe's dark sector. Climate action taken by the world today wouldn't be noticed for decades to come, according to scientists who say warming on Earth won't start to slow down for at least 20 years—and that's probably an optimistic scenario. New research finds that ships are hitting large numbers of small marine animals, which are suffering severe injuries or dying at higher rates than previously thought. A comet swept past the sun on July 3, and it has since become visible to the naked eye. The rare opportunity to glimpse the chunk of ancient ice should continue next week. If you manage to spot and photograph Comet NEOWISE, send us your favorite images to @sciam on Twitter with the hashtag #EyesOnNEOWISE.
