Researchers advance toward engineering 'wildly new genome'

In two parallel projects, researchers have created new genomes inside the bacterium E. coli in ways that test the limits of genetic reprogramming and open new possibilities for increasing flexibility, productivity and safety ...

New Duqu virus linked to Microsoft Word Documents

I new virus has cropped up in various countries across the world and its target appears to be corporate networks. The Duqu virus, first noted last month by a laboratory at Budapest University, has now been spotted in several ...

Sensor based on quantum physics could detect SARS-CoV-2 virus

A novel approach to testing for the presence of the virus that causes COVID-19 may lead to tests that are faster, less expensive, and potentially less prone to erroneous results than existing detection methods. Though the ...

15,000-year-old viruses discovered in Tibetan glacier ice

Scientists who study glacier ice have found viruses nearly 15,000 years old in two ice samples taken from the Tibetan Plateau in China. Most of those viruses, which survived because they had remained frozen, are unlike any ...

Study identifies new 'hidden' gene in COVID-19 virus

Researchers have discovered a new "hidden" gene in SARS-CoV-2—the virus that causes COVID-19—that may have contributed to its unique biology and pandemic potential. In a virus that only has about 15 genes in total, knowing ...

Criss-crossing viruses give rise to peculiar hybrid variants

For millions of years, viruses have participated in a far-flung, import-export business, exchanging fragments of themselves with both viral and non-viral agents and acquiring new features. What these tiny entities lack in ...

Viruses can steal our genetic code to create new human-virus genes

Like a scene out of "Invasion of the Body Snatchers," a virus infects a host and converts it into a factory for making more copies of itself. Now researchers have shown that a large group of viruses, including the influenza ...
