Coronavirus (COVID-19)
News and updates on the novel coronavirus, COVID-19.
-
Researchers suggest the 1918 influenza pandemic caused a wave of heart disease in the 20th century. With new evidence showing the impact of COVID on our hearts, could this recent pandemic be setting us up for another century of cardiac problems?
-
A single-shot vaccine that protects against multiple coronaviruses, including the one that causes COVID-19, has been developed. It erased all viral traces from the lungs of animal subjects, opening a pathway for a similar human vaccine.
-
A man that police caught taking 217 doses of COVID vaccine has offered himself up to researchers for a study looking into what happens to the immune system after so many doses. The results offer surprising insight into these new mRNA vaccines.
-
Even mild cases of COVID cause significant, measurable cognitive deficits compared to those never infected with the virus, according to one of the largest studies of its type. COVID brain fog is real, and it can sap up to six IQ points for at least a year.
-
Ever since SARS-CoV-2 emerged, the virus has been known for its novel effects on the brain. But exactly how is it causing these symptoms? A new study suggests that the answer lies in the way our vagus nerve talks to the brain.
-
A new study may explain the variable severity of SARS-CoV-2 from person to person. Using AI-driven machine-learning researchers discovered the virus is broken down into fragments, and this debris resembles peptides that overstimulate the immune system.
-
Using a virus-mimicking DNA scaffold instead of the usual protein one to deliver a vaccine to mice not only generated a robust immune response but avoided the off-target effects sometimes seen when proteins are used.
-
Researchers have identified a blood protein ‘signature’ in the complement system, part of the immune system, of patients with long COVID that may improve the diagnosis and lead to a treatment for the debilitating condition.
-
The first study of its kind has looked at every UK resident – more than 67 million people – across four months, and found that, as vaccine uptake tapered off in 2022, 7,180 hospitalizations and deaths could have been avoided had jabs been up to date.
-
Exercise is usually a good thing but for many long COVID patients it can often make their condition worse. Two new studies are shedding light on this counter-intuitive phenomenon, finding distinct physiological abnormalities in long COVID patients.
-
Researchers have developed a novel intranasal COVID-19 vaccine that enhances the immune system’s response to the virus, providing longer-lasting, greater protection than vaccine injections, even against new and emerging variants.
-
Researchers developed an AI algorithm that automatically analyzes chest X-rays to rapidly detect COVID-19 infection with more than 98% accuracy, distinguishing between normal X-rays and X-rays from people with viral pneumonia.
