كشف علماء في معهد ماكس بلانك عن «شفرة سكرية» خفية على سطح الخلايا البشرية باستخدام تقنية تصوير متقدمة تُسمى Glycan Atlasing. أظهرت النتائج أن أنماط السكريات تتغير مع نشاط الخلايا، وأن الأنسجة السرطانية تحمل بصمات سطحية مميزة مقارنة بالأنسجة السليمة، ما قد يساعد في الكشف المبكر عن المرض.
Scientists have uncovered a hidden “sugar code” on the surface of human cells that could transform how diseases are detected. Using an advanced imaging technique called Glycan Atlasing, researchers at the Max Planck Institute mapped the tiny sugar structures coating cells and discovered that these patterns shift depending on what the cell is doing.
Immune cells changed their sugar layouts when activated, and cancerous tissues displayed distinct surface signatures compared to healthy tissue.

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.
