ذباب ماص للدم يضحي ببصره بعد العثور على العائل

تكشف دراسة عن أن ذباب الغزلان الماص للدم يعتمد على الطيران والبصر للعثور على العائل، لكنه يغيّر أولوياته جذريًا بعد الهبوط. فبعد أن يتخلص من أجنحته نهائيًا، ينخفض نشاط جينات مرتبطة بالرؤية بنحو النصف لتوجيه الطاقة نحو التغذية والتكاثر.

  • Deer keds rely on flight and vision to find a host, but everything changes once they land. After shedding their wings forever, these parasites reduce the activity of key vision-related genes by about half. Scientists believe they are effectively trading sharp eyesight for extra energy that can be used for feeding and reproduction.

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.
