اختناقات البروتين قد تفسر ألزهايمر وفقدان الذاكرة

تشير دراسة من ستانفورد إلى أن تراجع الدماغ مع التقدم في العمر قد يرتبط بتعطل آلية تصنيع البروتين داخل الخلايا. وجد الباحثون أن تصادم الريبوسومات وتعثرها يؤديان إلى بروتينات معيبة وتكتلات ضارة مرتبطة بأمراض مثل ألزهايمر.

  • تكمن أهمية الاكتشاف في أنه يسلط الضوء على آلية خلوية مبكرة قد تصبح هدفًا لعلاجات تبطئ تدهور الدماغ المرتبط بالعمر.
  • Scientists at Stanford may have uncovered a hidden reason our brains decline with age. Studying the ultra-short-lived turquoise killifish, researchers discovered that the cellular machinery responsible for building proteins begins to jam and malfunction over time. Tiny structures called ribosomes start colliding and stalling while reading genetic instructions, triggering a chain reaction that leads to faulty proteins and harmful clumps linked to diseases like Alzheimer’s.

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.
