Concern about the Popocatepetl volcano changes with the wind. While east of the mountain residents swept streets and didn’t remove their masks on Tuesday, here to the west, they casually watched the gas and ash plume emerging from its crater.

The 17,797-foot (5,425-meter) mountain just 45 miles (about 70 kilometers) southeast of Mexico City and known affectionately as “El Popo,” has been belching for days, dusting towns and crops in Puebla in a super-fine ash.

“When nothing is happening we worry,” said a cheerful Viridiana Alba, who has been selling flowers in Amecameca’s central plaza for 25 years. “El Popo,” as the volcano is affectionately known, rises directly across from her stand.

“We know that right now it’s releasing smoke, that’s freeing the energy that it holds,” she said. Ash still rests on the awning that shades her plants from when the wind blew her way last weekend. The town was shaken by the volcano’s tremors, but as long as the ash remains light she believes it will help her plants.

Winds have blown a large plume of ash east over Puebla and Veracruz states and eventually the Bay of Campeche and beyond.

Mexico’s National Center for Prevention of Disasters said in its report Tuesday that small domes of lava continued forming inside the crater that were then being destroyed by small and moderate explosions. It advised that people living in communities near the volcano would likely continue those explosions over the coming days and weeks.

Three days ago “my house shook almost all night, it was amazing,” said Arturo Benítez, a former local official. “The sound of the volcano was strong, it resembled a lit boiler and a lot of ash fell, but then suddenly on this side it settled down.”

That was Sunday, when authorities raised the alert level, while maintaining there is not current risk to the population.

No evacuations have been ordered, but authorities have been driving evacuation routes, preparing some shelters and doing simulation drills.

On Cortes Pass, a small highway that crosses a saddle between Popocatepetl and the inactive Iztaccihuatl volcano, a couple dozen civil defense vehicles and soldiers blocked the way Tuesday.

The road was closed to traffic and most of the cabins that draw tourists were empty.

Cástula Sánchez, 75, who sells food to tourists on the weekends, was confident Popocatepetl would settle down again and the tourists would return. She lives in nearby San Pedro Nexapa where three decades ago lava arrived close to her home before they could evacuate, but they were spared.

Now she runs a local information service from the back of her shop. Residents bring her short messages scribbled on a piece of paper that she then reads over a loudspeaker the whole community can hear. So far authorities have asked nothing of her, just to keep an eye out.

In Amecameca, police handed out pamphlets with tips on being prepared in case the volcano’s activity increased. The pamphlet recommended having important documents at hand, a full gas tank, masks and towels to dampen if residents had to leave in a hurry.

Most residents already know, especially those who remember an eruption in 1997 that “darkened the sky, thundered ... and a muddy rain fell,” Benítez said.

“The pyroclastic cloud came to Amecameca and it was chaos, everyone wanted to leave then and it was tremendous,” he said.

The only time Popocatepetl triggered a red alert on the government’s stoplight-style system since emerging from decades of dormancy in 1994 was in 2000. The volcano’s last major eruption was more than 1,000 years ago.

The activity this time has so far not been significant for locals, but the localized impacts could be real for residents on one side of the volcano while everything is normal on the other.

Benítez who worked years ago as a photographer with federal authorities monitoring the volcano said he thought coverage in recent days had been a bit exaggerated. “It’s not that bad, except if they know something we don’t know, because the activity has lessened.”

President Andrés Manuel López Obrador too downplayed the situation Tuesday.

“We are going to be watching and if there's anything we're going to inform,” he said. “But we feel like there isn't going to be a problem.”

Heavy snowfall in Poland caused tailbacks stretching as far as 20 km (12.43 miles) on a motorway between ​the capital Warsaw and the Baltic port city of Gdansk during the night, police said on Wednesday.

While the situation left hundreds of people trapped in their cars in freezing conditions, by the early hours of ‌Wednesday morning traffic ‌was moving again, ‌according ⁠to ​police.

"The ‌difficult situation began yesterday after 4 p.m., when the first trucks on the S7 route... began having trouble approaching the slopes," said Tomasz Markowski, a spokesperson for police in the northern city of ⁠Olsztyn.

"This led to a traffic jam stretching approximately ‌20 kilometers overnight." Deputy Infrastructure Minister ‍Stanislaw Bukowiec ‍told a press conference that nobody had ‍been hurt as a result of the difficult situation on the roads.

Anna Karczewska, a spokesperson for police in Ostroda, said officers had ​tried to help drivers who found themselves stuck. Ostroda lies on ⁠the highway about 40 km west of Olsztyn.

"We helped as much as we could, and we had coffee and hot tea for the drivers, which the Ostroda City Hall had prepared for us," she said.

State news agency PAP reported that there had also been some disruption to railways and airports, ‌but that services were returning to normal.

Infant Screen Exposure Shapes Long-Term Brain Changes and Teen Anxiety, Study Finds

Children exposed to high levels of screen time before age two showed changes in brain development that were linked to slower decision-making and increased anxiety by their teenage years, according to new study released by the Agency for Science, Technology and Research in Singapore.

Prepared in collaboration with the National University of Singapore (NUS) Yong Loo Lin School of Medicine, the study focuses on infancy, a period when brain development is most rapid and especially sensitive to environmental influences.

The amount and type of screen exposure in infancy are largely determined by parental and caregiver awareness and parenting practices, highlighting a critical window for early guidance and intervention, showed the study, published in eBioMedicine on Tuesday.

It said the researchers followed 168 children before age two and conducted brain scans at three time points (ages 4.5, 6, and 7.5), which allowed them to track how brain networks developed over time rather than relying on a single snapshot.

Children with higher infant screen time showed an accelerated maturation of brain networks responsible for visual processing and cognitive control.

The researchers suggest this may result from the intense sensory stimulation that screens provide. Notably, screen time measured at ages three and four did not show the same effects, underscoring why infancy is a particularly sensitive period.

The study showed that children with high screen exposure, the networks controlling vision and cognition specialized faster, before they had developed the efficient connections needed for complex thinking. This can limit flexibility and resilience, leaving the child less able to adapt later in life.

It said this premature specialization came at a cost: children with these altered brain networks took longer to make decisions during a cognitive task at age 8.5, suggesting reduced cognitive efficiency or flexibility.

Those with slower decision-making, in turn, reported higher anxiety symptoms at age 13. These findings suggest that screen exposure in infancy may have effects that extend well beyond early childhood, shaping brain development and behavior years later.

In a related study, the same team found that infant screen time is also associated with alterations in brain networks that govern emotional regulation — but that parent-child reading could counteract some of these brain changes.

Researchers found that their results give a biological explanation for why limiting screen time in the first two years is crucial.

“But it also highlights the importance of parental engagement, showing that parent-child activities, like reading together, can make a real difference,” said Asst Prof Tan Ai Peng, Clinician-Scientist at NUS, and the study's senior author.

The study concluded that children exposed to high levels of screen time before age two are exposed to endure adolescent mental health, particularly on cognitive performance and anxiety levels.

Indonesian authorities have raised the alert level for the Mount Bur Ni Telong volcano in the country’s westernmost province of Aceh to its second highest following a series of increased activity and volcanic earthquakes, official said Wednesday.

The 2,624-meter (8,600-foot) stratovolcano in Aceh's Bener Meriah regency recorded at least seven earthquakes on Tuesday evening that were felt about five kilometers (three miles) away, while seismographs also detected seven shallow volcanic earthquakes along with 14 deep quakes and two tectonic quakes, said Lana Saria, the acting head of the Geological Agency at Energy and Mineral Resources Ministry.

She said based on the results of visual and instrumental monitoring which show the occurrence of increased volcanic activity for Mount Bur Ni Telong, scientists raised the alert level from the third to the second highest level Tuesday evening.

“Aftershocks following local tectonic events indicate magma activity is easily triggered by tectonic disturbances,” Saria said, adding that the increase in seismic activity has been ongoing since July and became more intense and shallow in the past two months.

According to The Associated Press, the agency's visual monitoring showed the volcano clearly visible with no crater smoke. However, she warned of possible eruption, including phreatic blasts and hazardous volcanic gases near areas with fumaroles and solfataras, openings in the Earth’s crust that emit steam and gases.

Authorities urged residents and visitors to stay at least 4 kilometers (2.4 miles) from the crater and avoid fumarole and solfatara zones during cloudy or rainy weather because gas concentrations can be life-threatening.

The heightened alert came as the Bener Meriah area is still recovering from catastrophic floods and landslides earlier this month that struck 52 cities and regencies on Sumatra island, leaving 1,141 people dead with 163 residents still missing and more than 7,000 injured, the National Disaster Management Agency said. In Bener Meriah alone, 31 people died and 14 are still missing after the floods and landslides hit the regency, disrupting access to remote villages and displacing more than 2,100 residents.

Local media said people living in three villages within a 2-kilometer (1.2-mile) radius from the crater are being evacuated as officials fear that heavy rains combined with volcanic activity could worsen conditions and complicate evacuation efforts.

Indonesia, an archipelago of more than 280 million people, has over 120 active volcanoes. It is prone to volcanic activity because it sits along the “Ring of Fire,” a horseshoe-shaped series of seismic fault lines around the Pacific Ocean.
