  • اكتشف العلماء أن حلقة غنية بالغبار خارج مدار المشتري ربما عملت كمصنع كوني لتكوين الكويكبات البدائية. قد يساعد هذا الاكتشاف في تفسير أصل أنواع غامضة من النيازك التي تعود إلى بدايات تشكل النظام الشمسي.
  • تكمن أهمية الاكتشاف في أنه يربط بين ديناميكيات الغبار قرب المشتري وتركيب النيازك، ما يمنح العلماء نافذة أوضح على المراحل الأولى لتكوّن النظام الشمسي.
  • Scientists believe a dust-filled ring just outside Jupiter acted like a cosmic “planetesimal factory,” producing multiple generations of early space rocks with very different compositions. The discovery may finally explain the origins of several mysterious meteorite types that have survived since the birth of the Solar System.

Why middle age is becoming a breaking point in the U.S.

A new international study finds that middle-aged Americans are lonelier, more depressed, and experiencing worse memory and health than earlier generations. Researchers say growing financial strain, weaker social supports, and chronic stress may explain why the U.S. is falling behind other wealthy nations.

Scientists mapped every neural connection in a fruit fly and found a surprise

A groundbreaking new connectome maps every neural connection in an adult fruit fly’s central nervous system, creating an unprecedented view of how the brain and body work together. The findings suggest that complex behaviors emerge from distributed local circuits rather than a single central controller, offering new clues about intelligence, movement, and brain function.
