New Giant Virus: The Emergence of Complex Life

The discovery of the Medusavirus holds clues to the evolution of more complex life. The paper published in the Journal of Virology earlier this year has been creating waves; because of the ability of the Medusavirus to turn amoeba into “stone.” However, the bigger discovery is the possible relationship between the Medusavirus; and the evolution…

H3N2 Viruses Mutate During Vaccine Production

In late March 2019, the World Health Organization; and a vaccine advisory committee of the Food and Drug Administration; selected the final influenza strains; to include in the vaccines produced for the next flu season.

Molecules Could Trap Viruses Inside A Cell

Viruses are often; used as vehicles for delivery in gene therapy; because they’re; engineered not to damage the cell once they get there; but neglecting to consider; how the virus will exit the cell could have consequences. Some viruses use a molecule called heparan sulfate; to help them attach to cells. The molecule, found in…

Cold Plasma Can Kill 99.9% of Airborne Viruses

Dangerous airborne viruses are; rendered harmless on-the-fly when exposed to energetic; charged fragments of air molecules; University of Michigan researchers have shown. They hope to one day harness this capability to replace a century-old device: the surgical mask. The U-M engineers have measured the virus-killing speed; and effectiveness of nonthermal plasmas — the ionized, or…
