Ed grabbed the big takeaway from the splashy new Vanity Fair piece this morning, that federal efforts to investigate the lab-leak theory were hamstrung by numerous conflicts of interest within the public-health bureaucracy.
But here’s a provocative bit of news buried deeper in the story that’s worth some attention.
There’s no smoking gun of wrongdoing, just an … interesting coincidence.
As the NSC tracked these disparate clues, U.S. government virologists advising them flagged one study first submitted in April 2020.
Eleven of its 23 coauthors worked for the Academy of Military Medical Sciences, the Chinese army’s medical research institute. Using the gene-editing technology known as CRISPR, the researchers had engineered mice with humanized lungs, then studied their susceptibility to SARS-CoV-2. As the NSC officials worked backward from the date of publication to establish a timeline for the study,
Dynamic mapping of the cell-generated force of cardiomyocytes will help provide an intrinsic understanding of the heart. However, a real-time, dynamic, and high-resolution mapping of the force distribution across a single living cell remains a challenge. Here, we established a force mapping method based on a “light nano-antenna” array with the use of piezo-phototronic effect. A spatial resolution of 800 nm and a temporal resolution of 333 ms have been demonstrated for force mapping. The dynamic mapping of cell force of live cardiomyocytes was directly derived by locating the antennas’ positions and quantifying the light intensities of the piezo-phototronic light nano-antenna array. This study presents a rapid and ultrahigh-resolution methodology for the fundamental study of cardiomyocyte behavior at the cell or subcellular level. It can provide valuable information about disease detection, drug screening, and tissue engineering for heart-related studies.
Several cities across China have recently started offering residents a single-dose COVID-19 vaccine in addition to the two-dose inactivated vaccines that were already widely used in the country's vaccination drive.
