A pioneering study reports on the interaction of a tailored titanium oxide nanoparticle (NP) with the full-length SARS-CoV-2 non-structural protein 1 (nsp1). This should be of value in developing new therapeutic tools against...
A new study reports the use of a modified deoxyribonucleic acid (DNA) oligonucleotide that has a 3’ polyadenine (polyA) tail to bind to the 5’-polyU tract in the mouse coronavirus (MHV-A59). Treatment of mouse cells infected with MHV-A59...
An intriguing new study presents a novel approach to biosensor-based evaluation of promising drugs that could inhibit the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) via its 3C-like protease (3CLpro), a viral protease.
Scientists in the Netherlands recently conducted an open-level, randomized-controlled trial to evaluate the safety and immunogenicity of fractional intradermal doses of the mRNA-based COVID-19 vaccine mRNA-1273 (Moderna). The trial...
Florida Gov. Ron DeSantis (R) issued an executive order that forbids schools from mandating classroom masks, even as Florida breaks COVID-19 infection records.
A new study published in The New England Journal of Medicine found that in a very small number of cases, people with breakthrough infections might suffer long-lasting COVID-19 symptoms.
The study by researchers from the Ministry of Health, Madrid, Spain, published in the Center of Disease Control and Prevention’s journal Emerging Infectious Diseases, suggests that long-term care facility residents with prior SARS-CoV-2...
Researchers have just established a structural basis for two spike glycoprotein epitopes of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that are restricted to human leukocyte antigen (HLA) A2 molecules. More...
Researchers in the United States have conducted a study showing the difference in antibody evolution following vaccination against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) between people who have not previously been...
The White House’s chief medical adviser urged the millions of Americans not yet vaccinated to step up: "We’re looking to some pain and suffering in the future."
Researchers have used advanced electron microscopy (EM) technology to see how human viruses move in high resolution in a near-native environment. The visualization technique could lead to improved understanding of how vaccine candidates...
University of Maryland researchers discovered a way that Mycobacterium tuberculosis (Mtb), the bacterium that causes tuberculosis, can cause a person's immune cells to lower their defenses. Specifically, they identified a gene in the...
Treating obese mice with the cytokine known as TSLP led to significant abdominal fat and weight loss compared to controls. The animal model findings support the possibility that increasing sebum production via the immune system could be...
Researchers have discovered the underlying genetic cause of a rare childhood disorder that mimics inflammatory bowel disease, a finding that may help researchers uncover the roots of a host of other inflammatory and autoimmune disorders.
A new study of cells shows that antibodies produced by the body in response to COVID-19 may be triggering a blood clotting response in patients with severe disease.
A new article outlines how relaxing Covid-19 restrictions could pave the way for new vaccine-resistant virus mutations. It describes how we are in an 'arms race' with the virus and how rising cases could provide opportunities for it to...
The president said he was considering requiring COVID-19 vaccines for federal employees. At least one report said the mandate would be announced this week.
Some vaccinated people infected with the delta variant may be able to spread the virus to others, according to new scientific evidence cited by the CDC’s director.
"It’s truly revolting to hear a privileged ignoramus like yourself pretend to be a victim of segregation," one Twitter critic wrote, addressing the far-right lawmaker.
New research has identified potential treatment that could improve the human immune system's ability to search out and destroy cancer cells within the body. Scientists have identified a way to restrict the activity of a group of cells...
A new study reports that among individuals who had an allergic reaction to their first mRNA COVID-19 vaccine dose, all who went on to receive a second dose tolerated it. Even some who experienced anaphylaxis following the first dose...
