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.

Scientists discovered that eating grapes can actually change how your skin behaves at the genetic level. After just two weeks of daily grape consumption, volunteers showed signs of improved skin protection and reduced oxidative stress from UV exposure. Researchers say the effects appear widespread, even though every person’s genes responded a little differently.

Deep learning (DL) has shown success in predicting Alzheimer's disease (AD) diagnosis, yet continuous measures such as cognitive assessment remain critical for richer prognosis, trajectory tracking and clinical trial enrichment. Current neurocognitive batteries are time-consuming, and the few DL models predicting cognition require expensive multimodal neuroimaging and longitudinal data. Although magnetic resonance imaging (MRI) is the most clinically accessible modality, on its own it struggles...
