Gut microbiome manipulation could result from virus discovery

Scientists have discovered how a common virus in the human gut infects and takes over bacterial cells—a finding that could be used to control the composition of the gut microbiome, which is important for human health.

Sorting out viruses with machine learning

The ongoing global pandemic has created an urgent need for rapid tests that can diagnose the presence of the SARS-CoV-2 virus, the pathogen that causes COVID-19, and distinguish it from other respiratory viruses. Now, researchers ...

Researchers identify new Rickettsia species in dogs

Researchers at North Carolina State University have identified a new species of Rickettsia bacteria that may cause significant disease in dogs and humans. This new yet unnamed species, initially identified in three dogs, ...

Researchers extract DNA from insects embedded in resin

For the first time, Senckenberg scientist Mónica Solórzano-Kraemer, together with lead authors David Peris and Kathrin Janssen of the University of Bonn and additional colleagues from Spain and Norway, successfully extracted ...

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 ...

Scientists discover new rules about 'runaway' transcription

On the evolutionary tree, humans diverged from yeast roughly 1 billion years ago. By comparison, two seemingly similar species of bacteria, Escherichia coli and Bacillus subtilis, have been evolving apart for roughly twice ...

Researchers discover how enzyme protects cells from DNA damage

A research team from Mount Sinai has unraveled for the first time the three-dimensional structure and mechanism of a complex enzyme that protects cells from constant DNA damage, opening the door to discovery of new therapeutics ...

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 ...
