Contribution of aquatic invertebrates to global nutrient supplies Global capture and aquaculture statistics To estimate the contribution of invertebrates to global animal capture fisheries and aquaculture production, we used 2019 reconstructed marine fisheries landings data from the Sea Around Us website25 and reported inland fisheries and aquaculture production from the Food and Agriculture Organization26. Reported inland

Under China’s Order 818, only high-level hospitals will be able to conduct investigator-initiated trials (IITs).Credit: Xinhua/Shutterstock In the past two months, reports that two children died after receiving gene-editing treatments in separate clinical trials in China have put a spotlight on the country’s fast-track trial pathway. Investigator-initiated trials (IITs) are a popular way that researchers
Editor’s Note: Today’s story is the answer to the September Puzzler. Several of the outcrops at Vasquez Rocks Natural Area in Southern California jut from the arid landscape of the Soledad Basin at remarkable angles. Geologists estimate that the tilt of sedimentary rock strata found in the area averages 50 degrees, steep enough that many
Explanation: Why are Saturn’s poles geometric? Saturn’s North Pole has been known to be surrounded by a hexagonal (6 sides) cloud since discovery in 1987 in data taken by NASA’s Voyager spacecrafts, which quickly flew past the ringed world in the early 1980s. Now, recent observations of Saturn by the Hubble Space Telescope reveal a slightly different geometric cloud pattern around the South Pole: a decagon (10 sides).
