Omicron resists antibodies, causes less severe disease than previous SARS-CoV-2variants

In two recent studies, researchers at Washington University School of Medicine in St. Louis found evidence that the omicron variant of the virus that causes COVID-19 causes less severe disease than previous variants — at least in rodents — but that many antibody-based therapies may not be effective against it.

Hepatitis E virus can resist most common hand disinfectants, research shows

In Germany and Europe, HEV has its natural reservoir in pigs. The infection can spread from animals to humans, which is called a zoonosis.

SARS-CoV-2 entry at the cell surface facilitated by trypsin

Exogenous trypsin treatment boosts SARS-CoV-2 infection in Vero E6 cells and promotes viral multiplication in cultured cells.

It’s Day 6 of covid, and a rapid antigen test comes back positive. stay home, say virologists.

What does it mean if a person's rapid antigen test result comes back positive after five days of isolation due to covid-19? According to the experts, that person is most likely still carrying a viral load high enough to infect others.

New study holds promise to help plants defend themselves against viruses

New research, led by Washington State University scientists, into how viral proteins interact and can be disabled holds promise to help plants defend themselves against viruses-;and ultimately prevent crop losses.

Study explains why Omicron infections are less likely to cause severe disease

A new study by researchers from the University of Kent and the Goethe University Frankfurt shows that the SARS-CoV-2 Omicron variant is less effective than Delta at blocking a cellular defense mechanism against viruses, the so-called “interferon response”.

Optical imaging reveals how cancer cells hijack metabolic activity to fuel pancreatic tumor growth

Pancreatic cancer is a rare, yet elusive and deadly cancer, with a five-year survival rate of about 10%. If the cancer has metastasized, that rate lowers to 3%. And treatment options are extremely limited.

Indian study suggests significant decrease in protection from vaccine or natural immunity against Omicron variant

Researchers present evidence for early community transmission of the SARS-CoV-2 Omicron variant in New Delhi, India.

Mice study identifies ventral spinocerebellar tract neurons that control locomotion

For more than a century, scientists have known that while the commands that initiate movement come from the brain, the neurons that control locomotion once movement is underway reside within the spinal cord.

Researchers detect Delta variant in the blood and placentas of women who had pregnancy complications

A growing body of evidence has linked the Delta variant of SARS-CoV-2, the virus that causes COVID-19, with an increased risk for pregnancy complications, including stillbirths.
