This week in Sunday Science links…
(1) Doubts have been raised about that Nature paper that used CRISPR to correct a lethal heart mutation in human embryos. Whenever a landmark paper is published, you often get some hard questions – significant breakthroughs require significant evidence. The criticisms raise valid questions, but I suspect the answer will be: “We need more evidence..and we’ll get it.”
(2) Where is all the plastic in the oceans going? The amount of plastic we discard and that ends up in the oceans is vast and horrifying. This is why some governments are mooting ideas such as a desposit-return scheme for plastic bottles. However, we still don’t know where in the oceans it’s all ending up. This article had a number of surprises for me: I did not know such a vast amount of the plastic in the ocean was discarded fishing gear, for example.
(3) And finally, this week’s featured image is a still from NASA’s grand finale short video of the Cassini spacecraft over Saturn. The spacecraft is nearing the end of it’s epic mission and will execute a planned burnout in the atmosphere of Saturn on September 15th. There is more information, including that video short, which is like a trailer for an epic scifi movie and is absolutely beautiful, here. The video linked below is the much longer NASA news conference:
