سرطان القولون والمستقيم يتزايد بشكل مقلق لدى البالغين الشباب، حتى في الثلاثينيات من العمر، دون عوامل خطر واضحة مثل التاريخ العائلي. دراسة سويسرية واسعة شملت نحو 100 ألف حالة على مدى أربعة عقود كشفت ارتفاعاً مستمراً في التشخيصات لدى من هم دون الخمسين، بينما تنخفض النسبة لدى كبار السن بفضل برامج الفحص المبكر. ويُشخص المرض غالباً في مراحل متقدمة لدى الشباب بسبب غياب الأعراض المبكرة وقلة الوعي السريري.
Colorectal cancer is increasingly showing up in younger adults, with cases now appearing in people as young as their thirties — often with no family history or warning signs. A major Swiss study analyzing nearly 100,000 cases over four decades found that diagnoses in people under 50 have been steadily climbing, even as rates fall among older adults thanks to screening programs.
Researchers say younger patients are also more likely to be diagnosed late, after the cancer has already spread.

A groundbreaking superconducting X-ray spectrometer has begun operation at BESSY II, giving Europe its first TES-based system and boosting photon detection efficiency by up to 1,000 times. The advance enables scientists to explore atomically thin materials, nanostructures, and ultra-dilute samples with remarkable speed and sensitivity.

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.

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.
