Hidden in the lungs of some breast cancer survivors are tumour cells that can remain dormant for decades — until they one day ...

We used health records of the Department of Veterans Affairs to build a study population of 441,583 veterans with SARS-CoV-2 infection between March 1, 2020, and January 31, 2022, and 4,748,504 ...

To determine whether multiple SARS-CoV-2 infections impact the risk for long COVID, Clouston and colleagues retrospectively studied data from 2,511 essential workers in New York, most of whom were ...

New evidence suggests that SARS-CoV-2 infection can lead to the rapid development of achalasia, a rare esophageal motility disorder. The etiology of achalasia is unclear. Studies have suggested an ...

Early in the beginning of the COVID-19 pandemic, scientists predicted the SARS-CoV-2 virus would mutate slowly. They were wrong. Hundreds of thousands of viral mutations and multiple seasonal ...

With climate change bringing more frequent and severe heat waves to much of the U.S. and the world, people will likely be spending even more time indoors in summertime—and so will SARS-CoV-2.

New genetic analyses reveal that the bat virus ancestors of SARS-CoV-1 and SARS-CoV-2 likely circulated in Western China or Northern Laos just years before human outbreaks. Their rapid appearance ...

Unfounded claims about SARS-CoV-2’s origin continue to circulate, further complicating efforts to maintain a constructive, evidence-based public discourse.

All pathogen proteins, like the SARS-CoV-2 spike, have invariant structures critical for their functions, making them good targets for mutation-tolerant drugs, as seen in our peptide engineering." ...
