U.S. deaths fell in 2022, as COVID-19 fatalities dropped by half from 2021 and the coronavirus dropped from being the nation’s third leading cause of death to the fourth. The Centers for Disease...
May 2, 20235:01 AM ET By Will Stone\ Scientists haven’t unraveled the cause of long COVID. But evidence is growing that an ongoing viral infection could be driving the symptoms, at least in some patients.Gary Waters/Fanatic Studio Brent Palmer’s first inkling about long COVID started in the early days of the pandemic, before the term...

Damian McNamara, MA April 13, 2023 If you or someone you know is experiencing “brain fog” after COVID-19, scientists now have a possible explanation — and it might not bring much comfort. Researchers in Germany found that part of the virus, the spike protein, remains in the brain long after the virus clears out. These investigators discovered...
David King Keller, PhD DISCLOSURES March 20, 2023 If a patient’s prostate specific antigen (PSA) spikes 2 points in just 90 days, what is your first thought? This patient has a strong likelihood of aggressive prostate cancer, right? If that same patient also presents with severe, burning bone pain with no precipitating trauma to the area and...

Credit: Shutterstock Newer variant-specific bivalent vaccines offer on average 1.6 times better immunity against COVID-19 than the original, single-strain “ancestral” vaccines, new research by UNSW’s Kirby institute published today in Nature Medicine shows. “We’re in an incredible...
By Simon Makin on March 1, 2023 Credit: Thomas Fuchs Artificial enzymes can fight the COVID-causing virus by selectively snipping apart its RNA genome, a new study suggests. Researchers say the technique may overcome key problems with previous technologies and could help create rapid antiviral treatments as threats emerge. When the COVID pandemic struck, University of Cambridge chemical...
