Nanorobot hand made of DNA grabs viruses for diagnostics and blocks cell entry

Science Daily: Pharmacology News

A tiny, four-fingered 'hand' folded from a single piece of DNA can pick up the virus that causes COVID-19 for highly sensitive rapid detection and can even block viral particles from entering cells to infect them, researchers report.

Virus that causes COVID-19 is widespread in wildlife, scientists find

Science Daily: Pharmacology News

SARS-CoV-2, the virus responsible for COVID-19, is widespread among wildlife species, according to new research. The virus was detected in six common backyard species, and antibodies indicating prior exposure to the virus were found in five species, with rates of exposure ranging from 40 to 60 percent depending on the species.

Over 160,000 new viruses discovered by AI

Science Daily: Pharmacology News

161,979 new RNA viruses have been discovered using a machine learning tool that researchers believe will vastly improve the mapping of life on Earth and could aid in the identification of many millions more viruses yet to be characterized.

How evolution tamed a deadly virus and why we should still worry

Science Daily: Pharmacology News

Over the last century, a once-deadly mosquito-borne virus has evolved so that it no longer sickens humans. New research shows that changes in the virus's ability to target human cells paralleled the decline in illness and death.

Infectious H5N1 influenza virus in raw milk rapidly declines with heat treatment

Science Daily: Pharmacology News

The amount of infectious H5N1 influenza viruses in raw milk rapidly declined with heat treatment in laboratory research. However, small, detectable amounts of infectious virus remained in raw milk samples with high virus levels when treated at 72 degrees Celsius (161.6

Engineering viruses to kill deadly pathogens

Science Daily: Pharmacology News

Researchers are exploring phages, viruses that infect bacteria, as a possible solution. In the new study, researchers successfully modified DNA from four types of phages to kill a deadly pathogen. Antimicrobial resistance is an urgent and growing global crisis.

What shapes a virus's pandemic potential? SARS-CoV-2 relatives yield clues

Science Daily: Pharmacology News

Two of the closest known relatives to SARS-CoV-2 -- a pair of bat coronaviruses discovered by researchers in Laos -- may transmit poorly in people despite being genetically similar to the COVID-19-causing virus, a new study reveals.
