What’s the difference between running the 100 meters, the 800 meters and running a marathon? We invited three elite runners to run on the world’s fastest treadmill to find out. nyti.ms/3ieCP4n
We used a super slow-motion camera to capture each runner’s stride and analyze how they run. This helped us show the differences between the running form of a sprinter, a middle-distance runner and a marathoner. nyti.ms/3ieCP4n
We learned from the lab at Southern Methodist University that the force a runner drives into the ground with each foot is the key to generating the right balance of speed and energy conservation in each type of race. nyti.ms/3ieCP4n

The Netherlands scored a goal against the U.S. women’s team in a quarterfinal match at #Tokyo2020. The team leads 1-0. If the Americans lose, they will be out of the tournament.
Seif al-Islam el-Qaddafi, the second son of the notorious dictator Muammar el-Qaddafi, is alive. In his first meeting with a foreign journalist in a decade, he talked to @robertfworth about his captivity — and hinted at a bid for Libya’s presidency. nyti.ms/2WvQKKR
“I’ve been away from the Libyan people for 10 years,” he told @robertfworth. “You need to come back slowly, slowly. Like a striptease.” He laughed. “You need to play with their minds a little.” nyti.ms/3rIiQy8
Until the Libyan uprising began in 2011, Seif was widely seen in the West as Libya’s best hope for reform. He had studied in London and spoke of democracy and human rights. But when the revolution came, he joined the Qaddafi regime’s brutal crackdown. nyti.ms/3rIiQy8
Sunisa Lee won the gold medal in the individual all-around gymnastics competition, continuing a U.S victory streak that began when Carly Patterson earned the title in 2004. nyti.ms/3xhaqim
Lee began her competition on the vault, which she executed cleanly. She landed her double-twisting Yurchenko with a slight bend in her hips, referred to as piking down, for a score of 14.6. nyti.ms/3xhaqim
Lee’s score on vault was fifth best in the competition, but on her next apparatus, the uneven bars, she ranked first. Overall, she scored 57.433, 0.135 better than Rebeca Andrade of Brazil. nyti.ms/3xhaqim
Simone Biles lost her way midair while vaulting in the women's gymnastics team final at #Tokyo2020 on Tuesday, later explaining that she'd been struggling with the pressure placed on her and wasn't in a good place to compete.
Biles had planned to do an Amanar, a difficult vault with 2.5 twists. But she completed only 1.5 twists, then lunged forward while landing. nyti.ms/376qJnI
Biles’s score was among the lowest on vault. Her withdrawal left the U.S. without its highest-scoring gymnast for the three other events. nyti.ms/376qJnI
Breaking News: Vaccinated people should resume wearing masks in schools and in public indoor spaces in parts of the U.S. where the coronavirus is surging, the CDC recommended on Tuesday, a sharp turnabout from its advice just two months ago. nytimes.com/2021/07/27/hea…
The CDC now advises universal masking in schools for teachers, staff, students and visitors, regardless of vaccination status and community transmission, as new data suggests even vaccinated people can spread the Delta variant. nytimes.com/2021/07/27/hea…
Vaccines are effective against the worst outcomes of infection with any form of the virus, including hospitalization and death. The new CDC guidance is an acknowledgment that the lagging vaccination effort has fallen behind the ever-evolving virus. nytimes.com/2021/07/27/hea…
The pandemic changed life for everyone, but in different ways. Data from the American Time Use Survey — which every year asks thousands of people to track every minute of a single day — reflects how Covid-19 led to a sudden rupture of daily life. nytimes.com/interactive/20…
2020 was a lonely year for many.
On average, people spent almost an hour longer each day alone in 2020 than in 2019. Seniors spent the most time alone. But it was young people, especially teenagers, who saw the biggest shift in their social lives. nyti.ms/3f3fT6e
With less time out of the house, Americans stared at screens a lot and groomed less.
Young people were the only group to spend more time on personal grooming in 2020 — and the only group to spend less time working out. nyti.ms/3f3fT6e
