أسئلة جديدة حول فيتامين B12 وخطر السرطان

تشير أبحاث جديدة إلى أن علاقة فيتامين B12 بالسرطان أكثر تعقيدًا مما كان يُعتقد. فالنقص قد يزيد تلف الحمض النووي ومخاطر السرطان، بينما قد ترتبط المستويات المرتفعة جدًا، خصوصًا من المكملات طويلة الأمد بجرعات عالية، ببعض السرطانات أو نتائج أسوأ لدى المرضى.

  • تبرز القصة أهمية التعامل مع المكملات الغذائية بحذر والاعتماد على التقييم الطبي بدل افتراض أن الجرعات الأعلى دائمًا أفضل.
  • Vitamin B12 has long been seen as a health hero, helping the body make red blood cells, repair DNA, and keep nerves functioning properly. But scientists are discovering that the story may be more complicated than simply “more is better.” While too little B12 can damage DNA and raise cancer risk, some studies suggest that extremely high levels — especially from long-term high-dose supplements — may also be linked to certain cancers or poorer outcomes in cancer patients.

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.
