Genomic sequencing is crucial in the battle against the coronavirus. These countries do it well

When South African scientists announced they had detected a new coronavirus variant with a worryingly high number of mutations, they were applauded for how quickly they were able to spot it.
The country was praised for having a robust genomic sequencing program, which allowed them to identify the potentially worrying properties of the variant now known as Omicron.
When viruses spread through populations, they mutate. Most mutations don't significantly alter a virus' behavior, but some can be concerning. Genomic sequencing involves decoding the genetic material of a virus to spot the mutations and determine what effect they might have on the virus -- for example whether they could make it more transmissible or more dangerous in terms of the severity of the illness it can cause.

Defense Secretary Pete Hegseth risked compromising sensitive military information that could have endangered US troops through his use of Signal to discuss attack plans, a Pentagon watchdog said in an unclassified report released Thursday. It also details how Hegseth declined to cooperate with the probe.

Two top House lawmakers emerged divided along party lines after a private briefing with the military official who oversaw September’s attack on an alleged drug vessel that included a so-called double-tap strike that killed surviving crew members, with a top Democrat calling video of the incident that was shared as part of the briefing “one of the most troubling things” he has seen as a lawmaker.
