Yesterday, Brigid Kosgei shattered the women's marathon world record, Simone Biles became the most decorated gymnast in world championship history and 15-year-old Coco Gauff won her first singles tennis title.

Running: A day after Kenya's Eliud Kipchoge's feat, his countrywoman Kosgei ran the Chicago Marathon in 2:14:04, besting the previous women's world record by more than a minute (2:15:25).

  • The big picture: "The two achievements made the weekend one of the most memorable in the modern history of long-distance running, with Kenya asserting its supremacy as the heartbeat of the sport," the New York Times wrote.

Gymnastics: Biles won gold medals in the balance beam and floor exercise to increase her career championship medal count to 25 — breaking Vitaly Scherbo's record of 24, which had stood for more than 2 decades.

Tennis: Gauff beat 2017 French Open champion Jelena Ostapenko, 6-3, 1-6, 6-2, in the finals of the Linz Open to claim her first WTA title.

  • Worth noting: Gauff is 2 years younger than either Serena or Venus Williams were when they won their first titles.

Biden extends mask mandates for travelers into 2022

President Biden will announce new testing protocols for international travelers on Thursday and extend masking requirements through March as the U.S. prepares to fight the Omicron variant this winter, according to senior administration officials.

Driving the news: The U.S. will tighten pre-departure testing protocols starting early next week by requiring all inbound international travelers to take COVID-19 tests within one day of their departure rather than three.

America probably won't lead the effort to understand Omicron

The race to figure out just how dangerous the Omicron variant is will likely be a global effort, but some experts are skeptical that the U.S. will play a dominant role.

Why it matters: The CDC has repeatedly come under fire for inadequate data collection throughout the pandemic — and figuring out how to respond to Omicron requires a lot of data that doesn't currently exist.

U.S. faces urgent anti-hacker crisis

The Biden administration is accelerating efforts to fill nearly 600,000 vacant cybersecurity positions in the public and private sectors bogging down efforts to protect digital infrastructure.

Why it matters: Following a deluge of ransomware attacks targeting critical government and corporate infrastructure this year, clogs in the talent pipeline are leaving federal, cash-strapped local governments and Big Business even more susceptible to hacking.
