Space: Harvard astrophysicist Avi Loeb suggests millions of interstellar fragments may be orbiting near Earth, based on two meteor candidates; the claim is speculative, and better detection could help test it. AI & Mathematics: OpenAI’s release of hundreds of AI-generated solutions to hard math problems has alarmed researchers, prompting calls for scrutiny and debate over how mathematicians’ work may change. Physics: Francis Halzen won the Nobel Prize for leading the Antarctic IceCube observatory, which detects cosmic neutrinos and opens a new way to study the universe. Astronomy: Researchers traced a record-distant fast radio burst to a small galaxy more than 10 billion light-years away. Planetary Science: NASA’s Perseverance rover set a Mars driving record, navigating autonomously for 28 miles. Earth & Environment: New satellite analysis found a Himalayan slope shifted up to 40 centimeters before a deadly disaster, underscoring risks from cascading mountain hazards. Meanwhile, the Chesapeake Bay earned its highest health score in 40 years, while forecasts warn a very strong El Niño could bring drought to parts of the Philippines early next year.
