Tulane University scientists published the first global assessment of ecological risks from ocean plastics, showing that the greatest dangers are not always in visible “garbage patches” but in areas where plastics overlap with dense marine life and pollutants. Their model maps worldwide “ecological risk hotspots,” highlighting threats from ingestion, entanglement, pollutant transport, and chemical leaching, with vulnerable zones including the North Pacific, North Atlantic, North Indian Ocean, and coastal East Asia. The study warns that risks could triple by 2060 without stronger action. But coordinated global efforts to reduce plastic use and improve waste management could significantly lessen the threats.

In 2015, NASA launched an unusual and brilliant exoplanet outreach campaign, offering retro-style posters, virtual guided tours, and even coloring books. The project quickly went viral worldwide. What explains the success of a campaign about a relatively young field of science that—unlike other areas of space research—lacks spectacular imagery?
Ceridwen Dovey, science communicator, writer, filmmaker, and researcher, has just published in the Journal of Science Communication (JCOM) a Practice Insight paper that presents a case study focusing on the Exoplanet Travel Bureau’s poster campaign. Dovey describes the productive working relationships between scientists and artists that produced this standout work and shows how, in contexts like this, artists are not merely in service to science but can also inspire research itself and help scientists clarify their own thinking.
The European Space Agency-led Solar Orbiter mission has split the flood of energetic particles flung out into space from the Sun into two groups, tracing each back to a different kind of outburst from our star.
Prof Heidi Newberg is an astrophysicist at Rensselaer Polytechnic Institute. Her research focuses primarily on understanding the structure of our own galaxy through using stars. In a newly published Frontiers in Astronomy and Space Sciences article, she and her co-authors lay out the case that a telescope with a rectangular mirror, rather than a roughly circular one as is used in traditional telescopes, could provide a clearer path to discovering habitable worlds. In the following guest editorial, she highlights the feasibility and advantages of this design.
