Barbados sheds allegiance to Britain

SAN JUAN, Puerto Rico – Barbados stopped pledging allegiance to Queen Elizabeth II on Tuesday as it shed another vestige of its colonial past and became a republic for the first time in history. Several leaders, dignitaries and artists, including Prince Charles and Rihanna, attended the ceremony that began late Monday in a popular square in the capital, Bridgetown, where the statue of a well-known British lord was removed last year amid a worldwide push to erase symbols of oppression.

Improved tracking

After a slow start, the United States has improved its surveillance system for tracking new coronavirus variants such as omicron, boosting its capacity by tens of thousands of samples per week. To find and track new versions of the coronavirus, scientists analyze the genetic makeup of a portion of samples that test positive. They’re looking at the chemical letters of the virus’s genetic code to find new worrisome mutants, such as omicron, and to follow the spread of known variants, such as delta. It’s a global effort, but until recently the U.S. was contributing very little. With uncoordinated and scattershot testing, the U.S. was sequencing fewer than 1% of positive specimens earlier this year. Now, it is running those tests on 5% to 10% of samples.
