Nanoporous material nets contaminant from water

Barely visible material that looks like tiny grains of sand may hold the key to removing an invisible health threat that has contaminated water supplies across the country. Researchers at Pacific Northwest National Laboratory ...

Nuclear pore complex outer rings: No longer 'one size fits all'

In eukaryotic cells, the nucleus is walled off from the rest of the cell by the nuclear envelope. All transport into and out of the nucleus occurs via cylindrical channels called nuclear pore complexes (NPCs) that penetrate ...

The clouds of spaghetti that keep DNA data safe

Cells can avoid "data breaches" when letting signaling proteins into their nuclei thanks to a quirky biophysical mechanism involving a blur of spaghetti-like proteins, researchers from the Rockefeller University and the Albert ...

Scientists map the portal to the cell's nucleus

Like an island nation, the nucleus of a cell has a transportation problem. Evolution has enclosed it with a double membrane, the nuclear envelope, which protects DNA but also cuts it off from the rest of the cell. Nature's ...

Team discovers new mechanisms for DNA stability

Researchers from the University of Seville at the Andalusian Centre for Molecular Biology and Regenerative Medicine have discovered that in eukaryotic cells, the proximity of the genes to the pores in the nuclear membrane ...

How shuttling proteins operate nuclear pores

Nuclear pore complexes are tiny channels where the exchange of substances between the cell nucleus and the cytoplasm takes place. Scientists at the University of Basel report on startling new research that might overturn ...

Colon cancer nuclear pore dynamics are captured by HS-AFM

One of the key reasons for cancer mortality is the highly invasive behaviour of cancer cells, which is often due to aggressive metastasis. Metastasis is facilitated by various growth factors and cytokines secreted from cells ...
