Small RNA as a central player in infections

More than half of the world's population carries the bacterium Helicobacter pylori in their stomach mucosa. It often causes no problems throughout life, but sometimes it can cause inflammation, and in some cases, it can even ...

Studying gene function in animal models

Researchers from the group of Jeroen Bakkers have described a thorough way to study the function of genes in model animals such as the zebrafish. In their study, published in Nature on September 23rd, they give an example ...

RNA information transfer could be used in repairing DNA

Genomes are routinely subjected to DNA damage. But most cells have DNA repair systems that enforce genome stability and, ideally, prevent diseases like cancer. The trouble gets serious when these systems break down. When ...

Origins of life: Chemical evolution in a tiny Gulf Stream

Chemical reactions driven by the geological conditions on the early Earth might have led to the prebiotic evolution of self-replicating molecules. Scientists at Ludwig-Maximilians Universitaet (LMU) in Munich now report on ...

Researchers explore the origins of stars rich in phosphorus

The journal Nature Communications has published the discovery of a new type of star that is very rich in phosphorus, which could help to explain the origin of phosphorous in our galaxy. This achievement has been made by astronomers ...

Epigenetics and cell diversity in the embryo

A research team at the Max Planck Institute for Molecular Genetics in Berlin has explored the role of factors in embryonic development that do not alter the sequence of DNA, but only epigenetically modify its "packaging". ...

The amazing travels of small RNAs

In most organisms, small bits of RNA play a key role in gene regulation by silencing gene expression. They do this by targeting and docking onto complementary sequences of gene transcripts (also RNA molecules), which stop ...
