Rare

• Gli astronomi hanno scoperto una rara sorgente di raggi X che fornisce informazioni cruciali sulla natura dei 'little red dots', galassie compatte dell'universo primordiale rilevate dal James Webb Space Telescope. • La scoperta, riportata l'11 maggio 2026, rivela che questi punti ospitano buchi neri supermassicci che accrescono attivamente materiale, spiegando così il loro intenso bagliore rosso e le loro dimensioni ridotte. • Questa svolta è fondamentale poiché risolve un enigma chiave della cosmologia, confermando i meccanismi di crescita dei buchi neri nel primo miliardo di anni dell'universo e aiutando l'interpretazione dei dati del JWST.

Numerose donne hanno raccontato di come sono state colpite dallo spettro della placenta accreta per una campagna di sensibilizzazione Numerose donne hanno dovuto sottoporsi a importanti interventi chirurgici d'urgenza, tra cui l'isterectomia, a causa del mancato rilevamento da parte del personale medico di una complicazione della gravidanza rara ma potenzialmente fatale.

Researchers find increase in whale deaths in the Bay, largely because of collisions with vessels on busy shipping routeGray whales have historically been a rare sight in the San Francisco Bay. They trek from the warm lagoons of Mexico’s Baja California over 10,000 miles north to the Arctic region to feast on shrimp-like animals during the summers, seldom stopping in the busy shipping corridor for prolonged periods.But in recent years, that story has changed in a dire way. A new study, published this week in the journal Frontiers in Marine Science, has found that gray whales in the Bay have been dying at alarming rates, largely due to collisions with vessels.

• Researchers at the Facility for Rare Isotope Beams (FRIB) directly measured the proton capture reaction of arsenic-73 forming selenium-74, the lightest p-nucleus, using a rare isotope beam. • Led by Artemis Tsantiri, the study involved over 45 scientists from 20 U.S., Canadian, and European institutions, published in Physical Review Letters. • This first-of-its-kind experiment sharpens models of p-nuclei formation, proton-rich heavy isotopes that have puzzled astronomers.
