New immune system discovered in bacteria

Like humans, bacteria have various immune systems to defend against pathogens such as viruses. These immune systems usually degrade the DNA of the pathogens to make it harmless. In the research group of assistant Professor ...

New CRISPR element regulates viral defense

What tasks need to be done today, and which is the most urgent? People have to constantly set priorities in their daily life. Bacteria are no different: They too must prioritize when combating viruses with CRISPR. However, ...

Targeted enzymes destroy virus RNA

A research team led by the Technical University of Munich (TUM) has successfully used specific enzymes to destroy the genetic information of SARS-CoV-2 directly after the virus penetrates the cell. The findings could serve ...

Sewer slime can hang on to SARS-CoV-2 RNA from wastewater

During the COVID-19 pandemic, monitoring the levels of SARS-CoV-2 RNA in wastewater entering treatment plants has been one way that researchers have gauged the disease's spread. But could the slimy microbial communities that ...

Research team finds nine new coronavirus species

A former UBC post-doctoral research fellow led an international research team in re-analyzing all public RNA sequencing data to uncover almost ten times more RNA viruses than were previously known, including several new species ...

Study rewrites dogma of adenovirus infection and double-stranded RNA

Challenging the dogma of what scientists thought they understood about DNA viruses, a team of researchers led by Children's Hospital of Philadelphia (CHOP) has shown that adenovirus uses its own efficient RNA splicing mechanisms ...

How poxviruses multiply

The last case of smallpox worldwide occurred in Somalia in October 1977. In 1980, the World Health Organization (WHO) declared the eradication of the smallpox. According to official sources, the virus continues to exist today ...
