Key Highlights
•
A new study shows that immune cells, like T cells, can actually grip and pull on their surroundings using integrin proteins when squeezing through tight spaces in 3D tissues. This finding overturns the old idea that these cells move only by pushing and sliding, revealing a more complex and adaptable migration strategy for fighting infections and cancer.

Researchers created a detailed single-cell map of the aging mouse brain, discovering that specific types of brain cells show unique patterns of DNA methylation changes and alterations in their 3D genome structure. This resource provides crucial insights into the molecular mechanisms of brain aging and could guide future research into age-related neurodegenerative diseases.

Scientists have discovered that the protein Atg2 acts as a reversible bridge, transferring essential fats from the cell’s warehouse (the endoplasmic reticulum) to the forming “recycling bin” (the autophagosome) and back again when needed. This reveals a precise control mechanism for cellular cleanup and energy management, crucial for health and preventing disease.

The evolutionary history of silicon transport proteins in sponges shows that the ability to build glass skeletons evolved independently at least four times as an adaptation to ancient, silicon-rich oceans. This finding rewrites our understanding of how complex biological structures can arise multiple times in response to environmental pressures.
