Investigators found gaps in White House logs of Donald Trump’s Jan. 6 calls.The House committee investigating the Jan. 6, 2021, attack on the Capitol has found few records of calls by President Donald Trump during critical hours when investigators know that he was making them.The sparse call records are the latest major obstacle to the panel’s mission: recreating what Trump was doing behind closed doors during the assault on Congress by a mob of his supporters.Call logs obtained by the committee document who was calling the White House switchboard, and any calls that were being made from the White House. Trump had a habit of circumventing that system by using his personal cellphone and those of his aides.Separately, the National Archives discovered what it believed was classified information in documents that Trump had taken with him from the White House as he left office, according to a person briefed on the matter.Seasonally adjusted.

January’s inflation was driven by food, electricity and shelter costs, the Bureau of Labor Statistics said.Inflation increasingly appears to be driven less by the pandemic and more by a strong economy. The new data added to expectations that the Fed will raise interest rates by half a percentage point in March.

Billions in infrastructure funding could worsen global warming.Building and expanding roads often just spurs people to drive more instead of reducing congestion, a phenomenon known as “induced traffic demand.” A new rule in Colorado, one of the nation’s fastest-growing states, marks a significant new approach.The state adopted a first-of-its-kind regulation that will redirect funding away from highway expansions and toward projects that cut vehicle pollution, such as buses and bike lanes. Colorado officials estimate the rule could reduce driving miles by 7 to 12 percent.In France, President Emmanuel Macron outlined plans to build up to 14 new-generation atomic reactors as the country seeks to slash planet-warming emissions. “The time has come for a nuclear renaissance,” he said.Patrick T.

Did the Black Death really kill half of Europe? New research says no.By analyzing ancient deposits of pollen as markers of agricultural activity, researchers from Germany found that the Black Death caused a patchwork of destruction. Some regions of Europe did indeed suffer devastating losses from the bubonic plague, but other regions held stable, and some even boomed.In the 14th century, most Europeans worked on farms. If half of all Europeans died between 1347 and 1352, agricultural activity would have plummeted. In Greece and central Italy, the pollen told a story of devastation. But in Ireland, central Spain and Lithuania, pollen suggested an increase in agricultural activity.The cap of Amelia Earhart that Anthony Twiggs inherited.Shelby Tauber for The New York Times10. And finally, an Amelia Earhart mystery solved (not that one).The response from the experts was always the same: So, your mom told you this aviator’s helmet belonged to Amelia Earhart?Anthony Triggs, a retired photographer, inherited the cap 20 years ago from his mother. She had told him that it was a gift from an admirer, who had found it on the ground during the Women’s National Air Derby of 1929, in which the legendary aviator finished third.To link his mother’s keepsake to Earhart, Triggs tried photo matching, comparing the headgear digitally with old photos. The results were promising, and a professional firm verified his findings. He’s happy about the windfall, but just as relieved that his mother’s story turned out to be true.Have an authentic evening.Eve Edelheit compiled photos for this briefing.
