The best time to see the meteor showers will be between midnight and dawn on both mornings, wherever you are in the world. If you live in an urban area, you may want to drive to a place that isn’t littered with city lights that will obstruct your view.

You’ve probably heard a lot about electric bicycles and electric scooters by now. These small personal electric vehicles (PEVs) are often touted as last mile vehicles that can help commuters travel short distances between home or work to other mass transit hubs, or as complete commuting alternatives in cities.

Still, the data trove has enabled Science, working with Retraction Watch, to gain unusual insight into one of scientific publishing’s most consequential but shrouded practices. Our analysis of about 10,500 retracted journal articles shows the number of retractions has continued to grow, but it also challenges some worrying perceptions that continue today. The rise of retractions seems to reflect not so much an epidemic of fraud as a community trying to police itself.

Better editorial oversight, not more flawed papers, might explain a flood of retractions.
