Scientists have discovered sugar-based molecules can be used to block activity of a receptor in cells that are involved in the development a range of viral infections and cancer.
The COVID-19 pandemic, caused by the SARS CoV-2 virus, continues to threaten populations around the world, after killing over 1 million Americans. In recent weeks, XBB.1.5, the most transmissible variant to date, has started ...
Despite their name, giant viruses are difficult to visualize in detail. They are too big for conventional electron microscopy, yet too small for optical microscopy used to study larger specimens. Now, for the first time, ...
New research shows that the closest bat virus relatives of the human Middle-East Respiratory Syndrome (MERS) coronavirus efficiently bind to bat ACE2 receptors as an entry point into these cells. These receptors have some ...
Researchers at McMaster University have created a powerful new weapon against bacterial contamination and infection.
Structural details of an attractive drug target in coronaviruses that could be used against SARS-CoV-2 and in future pandemics have been published by international teams co-led by UCL researchers.
A naturally occurring virus co-discovered by Agricultural Research Service (ARS) and university scientists may offer a way to undermine a costly fungal threat to wheat, barley and other small-grain crops.
Bats have lived with coronaviruses for millennia. Details are still hazy about how one of these viruses evolved into SARS-CoV-2, which causes COVID in humans. Did it go directly from bats to humans or via another animal species? ...
Ancient, dormant sequences in the genome impact embryonic development in unexpected ways. The mammalian genome contains retroviral sequences that are in an undead but mostly "harmless" state. An international research team ...
When Courtney "CJ" Johnson pulls up footage from her Ph.D. dissertation, it's like she's watching an attempted break-in on a home security camera.
