Medieval Russian talisman depicts Christian warrior saint and Medusa - Popular Science

Bear with me, because there is some backstory to get through before we can talk about the book I am actually here to review. Back in 1984, Stephen King and Peter Straub collaborated on the fantasy novel The Talisman. Like all the best King stories, it follows a young boy: in this case Jack Sawyer, 12, whose mother, Lily, is dying. Jack learns that a magical object called the Talisman might save her – if he can find it in a parallel world known as the Territories. Straub and King followed this up in 2001 with Black House, in which an adult Jack investigates a series of child murders that turn out to have disturbing links to the Territories. The books are very different: one a coming-of-age cross-country quest, in which Jack flips back and forth between two versions of the US; the other a fantastical and horror-inflected murder mystery. Both are brilliant and enduring classics which will always have a place on my bookshelves – I reread both of them, all 1,800-odd pages, to prepare for Other Worlds Than These and was as swept away and delighted as the first time round.

Milky Way’s first microblazar candidate sits 12,000 light-years away, offering a rare ground-level lab for studying relativistic jetsA black hole 12,000 light-years away is firing a jet of plasma almost directly toward Earth. At that distance, no known or expected danger to Earth has been identified by the researchers or the institutions involved. What astronomers have actually found is rarer and more interesting than a threat. Researchers have identified IRAS 18293-0941 as a compelling candidate for the Milky Way’s first microblazar, a class of object that gives astrophysicists a close-up laboratory for studying some of the most violent physics in the galaxy. What Astronomers FoundThe discovery centers on a binary system whose black hole expels plasma jets at close to three-quarters the speed of light, pointed almost directly toward Earth. The system pairs a hot, massive star with a black hole that completes a full orbit roughly every 11.38 days. Material drawn from the companion star feeds the black hole, and some of that matter gets expelled outward as opposing jets traveling at approximately three-quarters the speed of light. Terminology matters here.

Forests that stood on Mozambique's coast thousands of years ago now lie beneath shallow seas, and they have become fish-filled "peat reefs" with marine life comparable to coral reefs, researchers report in Scientific Reports. A team from the Bazaruto Center for Scientific Studies (BCSS) Ocean Observatory, led by Mario Lebrato, documented the submerged peat in the Bazaruto Archipelago in the Western Indian Ocean. BCSS, founded in 2017, describes itself as Africa's first permanent ocean observatory. Working with universities and institutions in the U. K., U. S. and Canada, the team believes it has carried out the first ecological study of peat reefs anywhere in the tropics. Old forests, new seafloorRadiocarbon dating shows the peat formed between about 300 and 5,000 years ago, and chemical analysis indicates it came mostly from coastal land plants and trees. Some samples contain up to 40% organic carbon by dry weight. Lebrato said the coastline has very little natural hard seabed, mostly shifting sand. As rising seas expose the old peat layers, they create rare solid habitat where marine life can settle, hide and feed.
