Scientists identify virus-cell interaction that may explain COVID-19's high infection rate
Bioengineering researchers at Lehigh University have identified a previously unknown interaction between receptors in human cells and the spike, or "S," protein of SARS-CoV-2, the virus that causes COVID-19. This new information ...

Looking for hidden states of the COVID-19 spike protein
The virus wreaking havoc on our lives is an efficient infection machine. Comprised of only 29 proteins (compared to our 400,000), with a genome 1/200,000 the size of ours, SARS-CoV-2 is expertly evolved to trick our cells ...

Study indicates SARS-CoV-2 variants are still transmissible between species
Scientists believe bats first transmitted SARS-CoV-2 to humans in December 2019, and while the virus has since evolved into several variants such as delta and omicron, a new study indicates the virus is still highly transmissible ...

BT-R3 mediates killing of the malaria vector Anopheles gambiae by Bacillus thuringiensis
Researchers at The University of Texas at Dallas (UTD), led by Dr. Lee Bulla, have demonstrated for the first time the selective cytotoxicity of Bacillus thuringiensis subsp. israelensis Cry4B toxin is mediated by BT-R3. ...

Fuzzy molecular threesome is basis of gene expression
Specific nuclear proteins act as a glue to pack genetic material in an absurdly small space in the human body. Proteins "gluing" DNA are called linker histones, and hold their secret in their electric charge. They are strongly ...
