After days of water-quality concerns caused by heavy rains last week put the swimming portion of the Olympic triathlons in doubt, the women dove into the Seine River early Wednesday, followed by the men a few hours later.

The athletes began near the Pont Alexandre III, a bridge that spans the famed Paris waterway. The women's race began under a gray sky, with steady rain tapering off just as the athletes splashed into the water. Some dunked their swim goggles in the Seine before putting them on and heading into the river with the Eiffel Tower in the background.

Italian researchers have noted the first case of "virgin birth", or reproduction without fertilization, in an endangered shark species, a scientific journal reported this week.

The findings published in Scientific Reports concern the first case of the phenomenon in the common smooth-hound shark, Mustelus mustelus, a species threatened by illegal fishing that inhabits the Mediterranean and other warm waters.

Swimming has been off-limits in the long-polluted Seine River in Paris for more than a century. So with Olympic swimming events on tap for the river, the city poured in $1.5 billion (1.4 billion euros) to try to clean it up.

With the Paris Games underway, officials are keeping a close eye on water quality. Athletes could feel health effects from swimming in a river with higher-than-accepted levels of E. coli or other bacteria.

Torrential rains have left at least seven people dead and three others missing in southeastern China, state media said Tuesday, raising the death toll from a tropical storm to 22.

All the deaths have been in Hunan province. Heavy rains have been falling on eastern Hunan for days as Tropical Storm Gaemi moved inland after making landfall at typhoon strength in neighboring Fujian province on the Chinese coast.

Lakes are dry and fields are scorched by heat in Sicily, but water is still gushing copiously for tourists.

After an almost totally rain-free year on the Italian island, fountains inside Agrigento's famous archaeological park are still flowing, and pools in rows of hotels are full.

Authorities have ordered multiple evacuations due to a wildfire on the island of Evia in southern Greece, with conditions worsening after nightfall when firefighting planes and helicopters were unable to operate.

The Fire Service said evacuations were ordered in four mountainous areas in the south of the island, located about 90 kilometers (55 miles) northeast of Athens. Several hundred firefighters and volunteers were deployed.

The 2024 Olympics famously launched with a rain-soaked opening ceremony that drenched athletes and spectators alike. Now, they're facing the opposite experience Tuesday: a heat wave.

Most of France is under a heat wave warning Tuesday, with temperatures in Paris and surrounding areas expected to climb to 35 C (95 F) or higher, the national weather agency said. Air conditioning is far less common in homes, shops and restaurants than in places like the United States.

Multiple landslides triggered by torrential rains in southern India have killed 70 people, and many others are feared trapped under the debris, officials said Tuesday, with rescue operations being hampered by bad weather.

The landslides hit hilly villages in Kerala state's Wayanad district early Tuesday and destroyed many houses and a bridge, but authorities have yet to determine the full scope of the disaster. Rescuers were working to pull out people stuck under mud and debris, but their efforts were hampered by blocked roads and unstable terrain.

Concerns about the water quality in the Seine River led officials to call off the swimming portion of an Olympic triathlon training session for a second straight day Monday.

Organizers overseeing the event at the Paris Games are optimistic that triathletes will be able to swim in the city's famed waterway when the competition starts Tuesday.

Warm morning light reflects from the remains of a natural rock arch near Darwin Island, one of the most remote islands in the Galapagos. In clear, deep blue water, thousands of creatures — fish, hammerhead sharks, marine iguanas — move in search of food.

The 2021 collapse of Darwin's Arch, named for the famed British naturalist behind the theory of evolution, came from natural erosion. But its demise underscored the fragility of a far-flung archipelago that's coming under increased pressure both from climate change and invasive species.
