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 Those the local doctor, Curtis Welch, had were outdated, but he wasn't worried.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.

Warsaw’s Celebrity Birds on Perilous Urban Quest

Waddling across a Warsaw expressway, a brood of wild sea ducks brought traffic to a halt as volunteers held motorists at bay -- an annual ritual to protect the bustling Polish capital's famous ducklings.

Every spring, dozens of days-old ducklings must make the risky trek from a centrally located park where they hatch to the Vistula river.

Local volunteers are mobilized to help ensure their safe passage, scrambling in hi-vis vests to stop cars and shepherd the birds across one of Warsaw's busiest roads.

Waddling through the city of 1.8 million people, the groups of mergansers -- fish-eating sea ducks -- are led by their silver-feathered mothers, with their distinctive brown head crests.

"We call mergansers ambassadors of Warsaw's wildlife -- or our celebrities," said Barbara Rozalska from the city parks department.

She was speaking over the rumble of the six-lane expressway -- "one of the biggest threats" for the wild birds on their kilometer-long journey.

Rozalska is in charge of coordinating the volunteers, who, through April and May, monitor the park and tree cavities where ducks lay their eggs and the possible routes they may take towards the river.

Around 30 people -- trained by the city's ornithologist -- take turns to stay alert for any sighting of the mergansers.

"It's a bit like being on call at the accident and emergency department -- you get a call and you have to go, no matter if it's at dawn or in the afternoon," Rozalska told AFP.

The array of threats is not limited to road traffic.

"There are seagulls and crows, which can snatch a chick that gets away from its mother for a moment. There are also predatory fish that can drag a chick underwater," she said.

- No honking -

One of the first merganser mums to cross this season took almost 24 hours to make it from the park to the river, testing the patience of the volunteers monitoring their every step and stumble.

That included the 11 hours the birds spent nestled in the roadside greenery, waiting for their moment.

Daria Grzesiek, 38, on duty, called it a "very difficult day" for her team.

"But once she set off and began making her way towards the Vistula... the fatigue was gone. There was only the satisfaction of having successfully guided her safely along the way," Grzesiek told AFP.

The volunteers' job involves asking passersby to keep their distance and put their dogs on a leash.

They also take on the task of explaining to drivers why the traffic needs to be stopped -- normally only for a few minutes.

As their efforts have gained traction and the birds have shot to local fame, there is more understanding among those sat behind the wheel, Grzesiek said.

One person, she recounted, "was getting upset that we stopped traffic".

But "the other drivers simply explained to him that he should calm down -- because mergansers are coming".

Deep in the Mediterranean Sea off the French coast, the pincer of a remotely guided underwater robot closed around a centuries-old jug resting near the wreck of a 16th-century merchant ship.

A French navy officer identified only as Sebastien, who did not disclose his full identity for security reasons, said handling the site requires extreme precision to avoid damaging the wreck or stirring up sediment that could impair visibility.

According to CBS News, Sebastien is overseeing the first mission in a series of archaeological explorations at what is considered the deepest shipwreck in French territorial waters, located about two hours from the French Riviera.

The shipwreck was discovered by chance last year during a routine military seabed survey off Ramatuelle, near Saint-Tropez. Archaeologists believe the vessel was sailing from northern Italy, carrying ceramics and metal ingots, before sinking.

The French navy has now returned, in cooperation with the culture ministry’s underwater archaeology department, to examine artifacts preserved at a depth of more than 1.5 miles below the surface.

Cannons and Ceramic Jugs on the Seabed

The navy is keeping the wreck’s location confidential, referring to it as “Camarat 4,” despite the fact that reaching it requires advanced technical capabilities due to its depth.

At dawn, a mission vessel arrived at the site carrying a remotely operated underwater robot, along with two large containers serving as field laboratories for marine archaeologists.

The robot, equipped with cameras and claw-like arms, was lowered into the depths via a long cable, while experts monitored its movements on screens.

After about an hour, it began gliding over piles of rounded ceramic jugs scattered across the seabed.

Images transmitted to the surface revealed details of the wreck, including cannons alongside hundreds of jugs and plates decorated with plant motifs, crosses and fish shapes.

The robot captured eight images per second over three hours, enabling the collection of more than 86,000 images, later used to produce a precise three-dimensional model of the site.

Archaeologist Franca Cibecchini said the clarity at that depth was striking: “It was excellent, something you wouldn’t imagine at this depth.” She added that the ship was likely a merchant vessel carrying glazed ceramics from Liguria in northwestern Italy, possibly loaded in the ports of Genoa or Savona.

Earlier surveys had identified two cauldrons, an anchor and six cannons at the site, along with modern debris such as a drinks can and an empty yogurt container visible near the anchor.

Recovering One of the Deepest Finds

Marine Sadania, head of the excavation team, said the findings represent an important source for understanding 16th-century maritime trade, given the limited detailed historical records available.

During the recovery operation, the team carefully guided the robot as it lowered its arm to gently lift a crate, although one ceramic piece broke during the process.

Several jugs and plates were successfully retrieved and later examined in laboratories in Marseille, where initial analysis revealed dark blue lines and multicolored geometric patterns.

Sadania said these items are among the deepest artifacts ever recovered from a shipwreck in France.

The discovery follows the 2019 identification of the submarine La Minerve off Toulon at a depth of about 1.4 miles. The vessel sank in 1968 with 52 sailors aboard.

In a separate development, officials announced the discovery of another 16th-century shipwreck found during military exercises off Sweden’s coast.

The bluebuck, an antelope with a silvery slate-blue coat and striking horns, inhabited the coastal grasslands of South Africa's southwestern Cape region until European settlers hunted it to extinction in around 1800. A US company now plans to resurrect the bluebuck as part of its de-extinction efforts.

Dallas-based Colossal Biosciences announced on Thursday that it has made the bluebuck the sixth species in its de-extinction portfolio based on genetic engineering, alongside three other mammals - the dire wolf, woolly mammoth and thylacine, also called the Tasmanian tiger - and two birds, the dodo and moa, Reuters reported.

"We're two years into the bluebuck project and have already completed several foundational steps," Colossal CEO and co-founder Ben Lamm told Reuters. "We are equally excited about how our technology can help living antelopes today. About a third of the world's roughly 90 antelope species are threatened or near-threatened."

Prized for the unique color of their hides, bluebuck were hunted to extinction just 34 years after the species was first documented scientifically. The animal stood about four feet (1.2 meters) tall at the shoulder, with backward-curving and ringed black horns reaching about 22 inches (56.5 cm) long, and was smaller than the closely related roan and sable antelopes.

"Humans did this. European settlers shot the bluebuck out of the Cape in under 34 years. There's no ambiguity about the cause and there's no ambiguity about the responsibility. If we have the capability to right that wrong, I think we have an obligation to," Lamm said.

The company in April 2025 announced the birth of three genetically engineered wolf pups created with the help of ancient DNA obtained from fossilized remains of dire wolves, an Ice Age predator that went extinct roughly 13,000 years ago. The process used to create them involved editing the genes of the gray wolf, the closest living relative of the extinct species, to add dire wolf traits, and creating an embryo.

In the case of the bluebuck, Colossal is editing the genes of an African antelope called the roan, its closest living relative.

"We are now in the genome-editing phase, where we introduce key bluebuck edits and genes into roan antelope cells," Lamm said, adding, "After finishing the various edits, the next step will be to use the edited cells to create an embryo and move toward implantation. From there, gestation would take about nine months."

The plan is for the embryo to be implanted into a surrogate roan mother. Through cloning, embryos were created from edited gray wolf cells in the dire wolf project, and these were implanted in surrogate domesticated dog mothers.

A MUSEUM SPECIMEN

Lamm said the company mainly used a mounted bluebuck skin from a young male specimen at the Swedish Museum of Natural History in Stockholm to obtain bluebuck DNA.

The team compared the bluebuck and roan genomes to understand what made the bluebuck unique, Lamm said, noting that the two species are more than 98% genomically similar. The team has created pluripotent stem cells in roan antelope - "essentially versatile 'starter cells' that can become many different cell types," Lamm said.

"We've also made breakthroughs in reproductive methods, including successfully collecting eggs from antelope species using advanced techniques," Lamm said.

Even as a growing number of species slip into oblivion due to human actions including hunting and habitat destruction, scientists have debated the ethics of attempting to resurrect extinct species.

"Honestly, I think the debate sometimes functions as a way to avoid a harder conversation, which is that conservation as currently practiced is not winning. We are losing species faster than our existing toolkit can address," Lamm said.

Colossal called the wolves it created dire wolves and referred to the species as the world's first successfully "de-extincted" animal. Some outside experts described them as genetically modified gray wolves.

"The dire wolves are doing great," Lamm said.

"The three dire wolves live on a 2,000-acre (810-hectare) secure, expansive ecological preserve that allows us to monitor and manage them while providing them a semi-wild habitat to thrive in. We hope to have more dire wolf pups by the end of the year. We will also have scientific progress announcements around the mammoth, dodo, thylacine and moa before the end of the year, but the projects are all running on track," Lamm said.
