Kind: research · Impact: medium

## In brief

- Researchers used fluorescent probes to examine nuclear pores in living human cells.
- Each nucleus has several thousand nuclear pores, and the pore scaffold structure is well known.
- The probes reveal fluid-like barriers inside the pores, which the source describes as previously unclear.

## Why it matters

The study offers direct observations of how the nuclear pore's internal environment may control which molecules pass into and out of the nucleus in living cells.
