The Alaska Gold Rush town of Nome faced a bleak winter. It was hundreds of miles from anywhere, cut off by the frozen sea and unrelenting blizzards, and under siege from a contagious disease known as the “strangling angel” for the way it suffocated children.
Now, 100 years later, Nome is remembering its saviors — the sled dogs and mushers who raced for more than five days through hypothermia, frostbite, gale-force winds and blinding whiteouts to deliver life-saving serum and free the community from the grip of diphtheria, The Associated Press reported.
Among the events celebrating the centennial of the 1925 “Great Race of Mercy” are lectures, a dog-food drive and a reenactment of the final leg of the relay, all organized by the Nome Kennel Club.
Remembering the mushers and dogs for ‘heroic effort’ “There’s a lot of fluff around celebrations like this, but we wanted to remember the mushers and their dogs who have been at the center of this heroic effort and ... spotlight mushing as a still-viable thing for the state of Alaska,” said Diana Haecker, a kennel club board member and co-owner of Alaska’s oldest newspaper, the Nome Nugget.
“People just dropped whatever they were doing," she said. "These mushers got their teams ready and went, even though it was really cold and challenging conditions on the trail.”
Other communities are also marking the anniversary — including the village of Nenana, where the relay began, and Cleveland, Ohio, where the serum run's most famous participant, a husky mix named Balto, is stuffed and displayed at a museum.
Jonathan Hayes, a Maine resident who has been working to preserve the genetic line of sled dogs driven on the run by famed musher Leonhard Seppala, is recreating the trip. Hayes left Nenana on Monday with 16 Seppala Siberian sled dogs, registered descendants of Seppala's team.
The historic trek to neutralize the diphtheria epidemic in Nome Diphtheria is an airborne disease that causes a thick, suffocating film to develop at the back of the throat; it was once a leading cause of death for children. The antitoxin used to treat it was developed in 1890, and a vaccine in 1923; it is now exceedingly rare in the U.S.
Nome, western Alaska’s largest community, had about 1,400 residents a century ago. Its most recent supply ship had arrived the previous fall, before the Bering Sea froze, without any doses of the antitoxin. Those the local doctor, Curtis Welch, had were outdated, but he wasn't worried. He hadn’t seen a case of diphtheria in the 18 years he had practiced in the area.
Within months, that changed. In a telegram, Welch pleaded with the U.S. Public Health Service to send serum: "An epidemic of diphtheria is almost inevitable here.”
The first death was a 3-year-old boy on Jan. 20, 1925, followed the next day by a 7-year-old girl. By the end of the month, there were more than 20 confirmed cases. The city was placed under quarantine.
West Coast hospitals had antitoxin doses, but it would take time to get them to Seattle and then onto a ship for Seward, an ice-free port south of Anchorage. In the meantime, enough for 30 people was found at an Anchorage hospital.
It still had to get to Nome. Airplanes with open-air cockpits were ruled out as unsuited for the weather. There were no roads or trains that reached Nome.
Instead, officials shipped the serum by rail to Nenana in interior Alaska, some 675 miles (1,086 kilometers) from Nome via the frozen Yukon River and mail trails.
Thanks to Alaska’s new telegraph lines and the spread of radio, the nation followed along, captivated, as 20 mushers — many of them Alaska Natives — with more than 150 dogs relayed the serum to Nome. They battled deep snow, whiteouts so severe they couldn’t see the dogs in front of them, and life-threatening temperatures that plunged at times to minus 60 degrees Fahrenheit (minus 51 degrees Celsius).
The antitoxin was transported in glass vials covered with padded quilts. Not a single vial broke.
Seppala, a Norwegian settler, left from Nome to meet the supply near the halfway point and begin the journey back. His team, led by his dog Togo, traveled more than 250 miles (320 kilometers) of the relay, including a treacherous stretch across frozen Norton Sound.
After about 5 1/2 days, the serum reached its destination on Feb. 2, 1925. A banner front-page headline in the San Francisco Chronicle proclaimed: “Dogs victors over blizzard in battle to succor stricken Nome.”
The official record listed five deaths and 29 illnesses. It’s likely the toll was higher; Alaska Natives were not accurately tracked.
Balto gains fame as unlikely dog to bring serum to Nome Seppala and Togo missed the limelight that went to his assistant, Gunnar Kaasen, who drove the dog team led by Balto into Nome. Balto was another of Seppala’s dogs, but was used to only haul freight after he was deemed too slow to be on a competitive team.
Balto was immortalized in movies and with statues in New York's Central Park and one in Anchorage intended as a tribute to all sled dogs. He received a bone-shaped key to the city of Los Angeles, where legendary movie actress Mary Pickford placed a wreath around his neck.
But he and several team members were eventually sold and kept in squalid conditions at a dime museum in Los Angeles. After learning of their plight, an Ohio businessman spearheaded an effort to raise money to bring them to Cleveland. After dying in 1933, Balto was mounted and placed on display at the Cleveland Museum of Natural History.
Iditarod pays homage to the serum run Today, the most famous mushing event in the world is the Iditarod Trail Sled Dog Race, which is not based on the serum run but on the Iditarod Trail, a supply route from Seward to Nome. Iditarod organizers are nevertheless marking the serum run's centennial, with a series of articles on its website and by selling replicas of the medallions each serum run musher received a century ago, race spokesperson Shannon Noonan said in an email. This year's Iditarod starts March 1.
“The Serum Run demonstrated the critical role sled dogs played in the survival and communication of remote Alaskan communities, while the Iditarod has evolved into a celebration of that tradition and Alaska’s pioneering spirit,” Noonan said.

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.
