What can a virus not do

Novel Virus Type May Shed Light on Viral Evolution

Oct. 16, 2019 — Viruses are non-living creatures, consisting of genetic material encased in a protein coat. Once the virus infects a living organism, it can replicate itself and continue on. But what happens if a ... read more


Viruses Can Transfer Genes Across the Superkingdoms of Life

Dec. 18, 2017 — A new finds that viruses can transfer genes to organisms that they aren't known to infect, suggesting they can influence and interact with a much wider range of organisms than previously ... read more

Mar. 29, 2018 — Bodo saltans virus, whose genome weighs in at 1.39 million bases of DNA, is one of the largest giant viruses ever isolated, and the largest known to infect ... read more


Structural Changes That Occur in Enveloped Viruses Before Invading Host

Aug. 21, 2018 — The critical, structural changes that enveloped viruses, such as HIV, Ebola and influenza, undergo before invading host cells have been revealed by scientists using nano-infrared spectroscopic ... read more


Ebolaviruses Need Very Few Mutations to Cause Disease in New Host Species

Feb. 15, 2017 — Ebola is one of the world's most virulent diseases, though rodent species such as guinea pigs, rats and mice are not normally susceptible to it. However, through repeated infection of a host ... read more


Ebola Virus Exploits Host Enzyme for Efficient Entry to Target Cells

Feb. 6, 2018 — Researchers have identified a key process that enables the Ebola virus to infect host cells, providing a novel target for developing antiviral ... read more


Viruses Support Photosynthesis in Bacteria

Feb. 23, 2017 — Viruses propagate by infecting a host cell and reproducing inside. This not only affects humans and animals, but bacteria as well. This type of virus is called bacteriophage. They carry so called ... read more


Cross-Species Jumps May Play Unexpectedly Big Role in Virus Evolution

Mar. 9, 2017 — On occasion, a virus may jump from one host species to another and adapt to the new host. Such cross-species transmission happens more often than expected, according to new research, and it may play ... read more


How MERS Coronavirus Evolves to Infect Different Species

Aug. 14, 2018 — New research shows how MERS-CoV can adapt to infect cells of a new species, which suggests that other coronaviruses might be able to do the ... read more


Novel Type of Virus Found in a Lake in Central Finland Links Virus Groups

July 19, 2017 — Viruses are the most numerous biological entities -- where is life there are viruses. Still, only a small fraction of them have been structurally and biochemically ... read more
