Welcome to the Weekend Briefing. We’re covering the coronavirus as the U.S. heads into a holiday week, the presidential transition and the Group of 20 summit. |

1. The U.S. is heading into a make-or-break holiday week. |
At least 255,000 Americans have died of the coronavirus, and hospitalizations rose beyond 82,000. Above, a memorial in Miami for virus victims. |
For many Americans, including the woman known as “Thanksgiving Grandma,” this will be the first Thanksgiving without a loved one at the table. Wanda Dench became internet famous when a misdirected text landed a stranger at her holiday table. Ms. Dench’s husband died from the coronavirus in April. |

2. A pharmaceutical giant and an upstart biotech firm are the front-runners in the race to create a vaccine. They were up against more than the virus. |
At play were not just commercial rivalries and scientific challenges between Pfizer and Moderna, but an ambitious plan to put the federal government in the middle of the effort, and President Trump’s bet that a vaccine would secure his re-election. |

3. The next three weeks are a moment of truth for the Republican Party. |
As election officials in contested states certify President-elect Joe Biden’s victory, verifying that the vote count is accurate and complete, G.O.P. officials from state capitols to Congress will be forced to choose between the will of voters and the will of one man: President Trump. |

4. The Trump administration is using its last weeks to lock in many of the president’s policies and interfere with President-elect Joe Biden’s agenda. |
Top officials are racing against the clock to withdraw troops from Afghanistan, secure oil drilling leases in Alaska, punish China, carry out executions and thwart any plans that Mr. Biden may have to reestablish the Iran nuclear deal. In some cases, Mr. Trump’s government plans to act just days — or even hours — before Mr. Biden is inaugurated on Jan. 20. |

5. Fighting the pandemic and its global economic impact dominated the Group of 20 summit, which began on Saturday and continues today. |
The virus reduced the annual summit to a giant webinar, transforming an event that was supposed to allow Saudi Arabia to play host to the world’s great powers and depriving Crown Prince Mohammed bin Salman, the country’s de facto ruler, of reviving his international reputation. |
6. Do these people look real? |
They may look familiar, but they don’t exist. We built an A.I. system to create fake faces like the ones used to fool people on Facebook, Amazon and even Tinder. |
The technology that makes them is improving at a startling pace thanks to a new type of artificial intelligence called a generative adversarial network. In essence, you feed a computer program a bunch of photos of real people. It studies them and tries to comes up with its own photos, while another part of the system tries to detect which of them are fake. |

7. An apology 52 years in the making. |
Lynn Conway was one of IBM’s most promising young computer engineers, but after confiding to supervisors in 1968 that she was transgender, they fired her. Last month, Ms. Conway, pictured in 2018, was called into a virtual meeting with IBM employees. |
Diane Gherson, IBM’s senior vice president of human resources, told Ms. Conway that although the company now offered help and support to “transitioning employees,” no amount of progress could make up for the treatment she had received decades ago. |
Ms. Conway, 82, was then given a lifetime achievement award for her “pioneering work” in computers. “It was so unexpected,” Ms. Conway said. “It was stunning.” |

8. Thanksgiving: Ready, set, don’t go (but do cook). |
With coronavirus cases raging across the U.S., the safest choice this Thanksgiving is to spend it with the people you live with. Here are ideas from across The Times for how to keep it small, safe and fun: |

9. Music to get us through. |
At the fearful height of the pandemic in April, Simon Gronowski, an 89-year-old Holocaust survivor, began playing jazz tunes on his piano from his apartment window in Brussels, bringing relief to his besieged neighbors throughout the lockdown that lasted into late May. |
“Music is a means of communication, of connection,” said Mr. Gronowski, who taught himself how to play the piano as a teenager after escaping the Nazis. Piano was a way for him to connect with his sister who had died in Auschwitz. |

10. And finally, take in these stories at your leisure. |
Rethinking the Thanksgiving myth. The fashion of Princess Diana. The cutthroat market for N95 masks. These stories and more await in The Weekender. |
Have a safe and healthy week. |
