What to know about avian influenza in dairy cows and the risk to humans
Why is H5N1, or bird flu, a concern, how does it spread, and is there a vaccine? Here are the answers to some frequently asked questions about avian influenza.
China's Yang Qian won the first gold medal of the Tokyo Olympics on Saturday after prevailing in a battle of nerves with Russian Anastasiia Galashina in the women's 10-metre rifle final.
Galashina barely made it to the final, grabbing the last of the eight qualifying slots, but was in pole position for gold until she cracked under the pressure.
That pressure also weighed heavily on South Korean shooting great Jin Jong-oh, whose quest for a record-extending fifth individual Olympic gold fell short when he failed to qualify for the final of the men's 10m air pistol.
Javad Foroughi comfortably beat an elite field to win gold, Iran's first ever shooting medal, with a Games record total of 244.8 in the final.
Foroughi told reporters he was able to maintain his composure in the final because he had stumbled in qualification but still made it through.
"That's why I was relaxed during the final because in the qualification round I was so nervous and still did well," he said.
Serbian Damir Mikec finished second on 237.9, ahead of 2008 Beijing Olympics champion Pang Wei of China. Defending Olympic champion Hoang Xuan Vinh of Vietnam could not make the final.
In the women's rifle final, Galashina's hopes were dashed by her last shot of 8.9, which was the lowest of any competitor in the final, leaving her on a total of 251.1.
Yang was not immune to the pressure at the Asaka Shooting Range either but her below-par final shot of 9.8 was still enough to snatch the gold with an Olympic record total of 251.8.
In the stands, supporters and team mates watched the nail-biting women's final, cheering to the rock music piped into the venue.
"We did train how to perform under pressure. The coaches would actually create a nerve-wracking atmosphere and try to pressure us," Yang told reporters after winning an event which did not feature a single medallist from Rio.
Galashina said the pressure got to her on the final shot.
"I got too nervous, held on too long. My thoughts were not in the right place. I lost concentration. The explanation is very simple," Galashina said.
