They're cool! They may have formed in the primordial universe, they comprise the seeds of supermassive black holes, and may be formed by the accretion of multiple stars in a cluster rather than through stellar collapse. https://phys.org/news/2024-07-saturday-citations-scientists-monkey-cat.html Other Sat, 20 Jul 2024 08:30:02 EDT news640614477 This week: Physicists conducted a biological study, engineers built a waste-recycling suit for astronauts (and worm riders), and astronomers identified the first known intermediate-mass black hole, and it's right here in our own galactic back yard. https://phys.org/news/2024-07-saturday-citations-goldilocks-black-hole.html Other Sat, 13 Jul 2024 09:30:01 EDT news640007335 The complexity of the melodies of the most popular songs each year in the U.S.—according to the Billboard year-end singles charts—has decreased since 1950, a study published in Scientific Reports suggests. https://phys.org/news/2024-07-song-melodies-simpler.html Other Social Sciences Thu, 04 Jul 2024 11:00:01 EDT news639238262 The coolest news this week concerns anthropological research combining state-of-the-art imaging technology, medical diagnostics, genetics and sociology.
