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 ...

How the cell protects itself

The cell contains transcripts of genetic material, which migrate from the cell nucleus to another part of the cell. This movement protects the genetic transcripts from the recruitment of "spliceosomes." If this protection ...

New tool can pinpoint origins of the gut's bacteria

A UCLA-led research team has developed a faster and more accurate way to determine where the many bacteria that live in, and on, humans come from. Broadly, the tool can deduce the origins of any microbiome, a localized and ...

DNA base editing induces substantial off-target RNA mutations

In a study published in Nature on June 10, researchers from Dr. Yang Hui's Lab at the Institute of Neuroscience of the Chinese Academy of Sciences (CAS), and collaborators from the CAS-MPG Partner Institute for Computational ...

Is sex primarily a strategy against transmissible cancer?

One of the greatest enigmas of evolutionary biology is that while sex is the dominant mode of reproduction among multicellular organisms, asexual reproduction appears much more efficient and less costly. However, in a study ...

Translation of genes more complex than expected

Researchers from Marvin Tanenbaum's group at the Hubrecht Institute have shown that translation of the genetic information stored in our DNA is much more complex than previously thought. This discovery was made by developing ...

How flow shapes bacterial biofilms

EPFL biophysicists have taken a systematic look into how bacterial biofilms are affected by fluid flow. The findings can give us clues about the physical rules guiding biofilm architecture, but also about the social dynamics ...

What organizes the genome in the nucleus?

Spatial separation of active from inactive fractions of the genome in the cell nucleus is crucial for gene expression control. A new study uncovers leading mechanisms of such separation and turns our picture of the nucleus ...

New genes out of nothing

One key question in evolutionary biology is how novel genes arise and develop. Swedish researchers now show how new genes and functions that are advantageous to bacteria can be selected from random DNA sequences. The results ...

Snapshots of the flu virus replication machine in action

Researchers from EMBL Grenoble have, for the first time, observed different functional states of the influenza virus polymerase as it is actively transcribing. These results, published in Nature Structural & Molecular Biology, ...
