Biologists reveal structure of cell nucleus 'gatekeeper'

(PhysOrg.com) -- Biologists led by associate professor Thomas Schwartz (MIT) have worked out a rudimentary architectural plan for the nuclear pore complex (NPC), the gatekeeper of the cell's nucleus.

The physics of extracting gas from shale formations

Extracting gas from new sources is vital in order to supplement dwindling conventional supplies. Shale reservoirs host gas trapped in the pores of mudstone, which consists of a mixture of silt mineral particles ranging from ...

Uncovering secret structure to safer explosives

A team of scientists at Lawrence Livermore National Laboratory (LLNL) has shown that the structure of microscopic pores in high explosive materials can significantly impact performance and safety. These findings —  published ...

Nanopores make sterile filtration more reliable

Irregular pores, low flow rates: The plastic membrane filters used in sterile filtration do not always ensure that conditions are really sterile. Filter membranes of aluminum oxide are more reliable - the size of the nanopores ...
