Vietnam's capital Hanoi has been covered in thick smog over recent weeks, putting it at the top of a list of the world's most polluted cities, as the government said it would push for more electric vehicles (EVs) to alleviate the problem.
Levels of hazardous small particles, known as PM2.5, were measured at 266 micrograms per cubic meter in Hanoi early on Friday, the highest reading among a list of most-polluted cities, according to AirVisual, which provides independent global air pollution information via a phone app.
The Southeast Asian country, a regional manufacturing hub with one of the fastest-growing economies in Asia, has reported severe air pollution in its major cities for years, particularly in Hanoi, Reuters said.
The thick smog is mostly caused by heavy traffic, trash burning and industrial activities.
"We the elderly can feel it very clearly when we suffer from respiratory problems that lead to breathing difficulties," Luu Minh Duc, a 64-year-old resident of the city, said. "The situation seems to get worse recently."
Young people are also complaining.
"At first I thought it was foggy ... but later I found out that it is actually fine dusts that reduce my vision and make me feel like it is not healthy to breathe," said 21-year-old student Nguyen Ninh Huong.
Speaking at a meeting with the transport ministry on Thursday, Deputy Prime Minister Tran Hong Ha called for an accelerated transition to electric vehicles (EVs) as part of the efforts to reduce pollution, state media reported.
So far Hanoi has a target for at least 50% of buses and 100% of taxis to be EVs by 2030.
"This is the responsibility of the state to the people, and there must be specific and timely actions," Ha was quoted as saying by the Tien Phong newspaper.
The ministries of natural resources, environment and health did not immediately respond to Reuters' requests for comment.



Mummified Cheetahs Found in Saudi Caves Shed Light on Lost Populations

Mummified Cheetahs Found in Saudi Caves Shed Light on Lost Populations

Scientists have uncovered the mummified remains of cheetahs from caves in northern Saudi Arabia.

The remains range from 130 years old to over 1,800 years old. Researchers excavated seven mummies along with the bones of 54 other cheetahs from a site near the city of Arar.

Mummification prevents decay by preserving dead bodies. Egypt's mummies are the most well-known, but the process can also happen naturally in places like glacier ice, desert sands and bog sludge.

The new large cat mummies have cloudy eyes and shriveled limbs, resembling dried-out husks.

“It’s something that I’ve never seen before,” said Joan Madurell-Malapeira with the University of Florence in Italy, who was not involved with the discovery.

Researchers aren’t sure how exactly these new cats got mummified, but the caves’ dry conditions and stable temperature could have played a role, according to the new study published Thursday in the journal Communications Earth and Environment.

They also don't know why so many cheetahs were in the caves. It could have been a denning site where mothers birthed and raised their young.

Scientists have uncovered the rare mummified remains of other large cats, including a saber-toothed cat cub in Russia.

It's uncommon for large mammals to be preserved to this degree. Besides being in the right environment, the carcasses also have to avoid becoming a snack for hungry scavengers like birds and hyenas.

Cheetahs once roamed across most of Africa and parts of Asia, but now live in just 9% of their previous range and haven't been spotted across the Arabian Peninsula for decades. That’s likely due to habitat loss, unregulated hunting and lack of prey, among other factors.

In a first for naturally mummified large cats, scientists were also able to peek at the cheetahs' genes and found that the remains were most similar to modern-day cheetahs from Asia and northwest Africa. That information could help with future efforts to reintroduce the cats to places they no longer live.

Lindsey Vonn may be dominating World Cup downhills at 41, but even the US speed queen is not immune to missing equipment.

Vonn took to social media on Thursday with an unusual plea after losing a ski pole in Tarvisio, Italy, ahead of this weekend's World Cup event.

"Someone took ‌my pole ‌in the parking ‌lot ⁠today in ‌Tarvisio. If you have seen it, please respond to this. Thank you," Vonn wrote on X, posting a photo of the matching pole complete with her initials on the ⁠hand strap.

Vonn, a favorite for the speed events ‌at next month's Milano-Cortina ‍Olympics, retired ‍from the sport in 2019 and ‍had a partial knee replacement in April 2024 but returned to competition later that year and has been enjoying a fairy-tale comeback that has defied age and expectation.

Already the oldest ⁠World Cup winner of all time, Vonn continued her astonishing, age-defying form with a downhill victory in Zauchensee, Austria last week.

That triumph marked Vonn's fourth podium from four downhills this season, cementing her lead in the World Cup standings and her status as the woman to ‌beat at next month's Olympics.

Four International Space Station (ISS) crewmembers splashed down in the Pacific Ocean early Thursday, video footage from NASA showed, after a medical issue prompted their mission to be cut short.

American astronauts Mike Fincke and Zena Cardman, Russian cosmonaut Oleg Platonov and Japan's Kimiya Yui landed off the coast of San Diego about 12:41 am (0841 GMT), marking the first-ever medical evacuation from the ISS.
