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 Those the local doctor, Curtis Welch, had were outdated, but he wasn't worried.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

Freezing rain led to flights being suspended at Vienna airport on Tuesday, while neighboring Slovakia, Czech Republic and Hungary also experienced travel disruptions.

Snow and freezing temperatures buffeted Europe last week, with gale-force winds and storms claiming some 15 lives, causing travel mayhem, shutting schools, and cutting power to hundreds of thousands.

A thick layer of ice on the Vienna airport runways led to arriving flights being diverted to other airports, while all departing flights were put on hold early Tuesday.

Austria's state railway company OeBB also asked travelers to postpone non-urgent journeys, with numerous train connections facing interruptions and cancellations.

In neighboring Slovakia, the Bratislava airport was also closed early Tuesday due to bad weather.

Slovak police on Facebook urged people to avoid travel because of "extreme" ice and snow in the west of the country.

In the Czech Republic, ice was also hampering road and rail traffic.

Prague airport came to a virtual standstill, with firefighters having to de-ice the runways.

Around 50 people were treated for injuries because of the icy conditions, according to Prague's emergency services, cited by the CTK agency.

In Hungary, meteorological services also issued alerts for freezing rain and snowfall as severe winter conditions affect a large part of the country.

Trains and flights were experiencing delays, while authorities reported drift ice on the Danube and the Tisza rivers, where icebreakers have been put on alert.

Lake Balaton in the west of the country is currently frozen -- a relatively rare phenomenon seen about once every ten to fifteen years.

However, authorities warned that the ice is still too thin for skating, urging the public to be cautious.


AI Helps Fuel New Era of Medical Self-testing

Beyond smart watches and rings, artificial intelligence is being used to make self-testing for major diseases more readily available -- from headsets that detect early signs of Alzheimer's to an iris-scanning app that helps spot cancer.

"The reason preventive medicine doesn't work right now is because you don't want to go to the doctor all the time to get things tested," says Ramses Alcaide, co-founder and CEO of startup Neurable.

"But what about if you knew when you needed to go to the doctor?"

Connected rings, bracelets and watches -- which were everywhere at last week's Consumer Electronics Show in Las Vegas -- can already monitor heart rate, blood pressure and glucose levels, with varying degrees of accuracy.

These gadgets are in high demand from consumers. A recent study published by OpenAI showed that more than 200 million internet users check ChatGPT every week for information on health topics.

On Wednesday, OpenAI even launched a chatbot that can draw on a user's medical records and other data collected by wearable devices, with their consent, to inform its responses.

Using electroencephalogram (EEG) technology, Neurable has developed a headset that records and deciphers brain activity.

The linked app compares data with the user's medical history to check for any deviation, a possible sign of a problem, said Alcaide.

"Apple Watch can pick up Parkinson's, but it can only pick it up once you have a tremor," Alcaide said. "Your brain has been fighting that Parkinson's for over 10 years."

With EEG technology, "you can pick these things up before you actually see physical symptoms of them. And this is just one example."

Detection before symptoms

Some people have reservations about the capabilities of such devices.

"I don't think that wearable EEG devices are reliable enough," said Anna Wexler, a University of Pennsylvania professor who studies consumer detection products, although she acknowledges that "AI has expanded the possibilities of these devices."

While Neurable's product cannot provide an actual diagnosis, it does offer a warning. It can also detect signs of depression and early development of Alzheimer's disease.

Neurable is working with the Ukrainian military to evaluate the mental health of soldiers on the front lines of the war with Russia, as well as former prisoners of war, in order to detect post-traumatic stress disorder (PTSD).

French startup NAOX meanwhile has developed EEG earbuds linked to a small box that can help patients with epilepsy.

Rather than detect seizures, which are "very rare," the device recognizes "spikes" -- quick, abnormal electrical shocks in the brain that are "much more difficult to see," said NAOX's chief of innovation Marc Vaillaud, a doctor by training.

NAOX's device -- which has been cleared by the US Food and Drug Administration -- is designed to be worn at night, to track several hours of data at a time.

The company is working with the Rothschild and Lariboisiere hospitals in Paris to try to better understand the links between these brain "spikes" and Alzheimer's disease, which have been raised in scientific papers.

Advances in AI and technology in general have paved the way for the miniaturization of cheaper detection devices -- a far cry from the heavy machinery once seen in medical offices and hospitals.

IriHealth is preparing to launch, for only about $50, a small smartphone extension that would scan a user's iris.

The gadget relies on iridology, a technique by which iris colors and markings are believed to reveal information about a person's health, but which is generally considered scientifically unreliable.

But the founders of IriHealth -- a spin-off of biometrics specialist IriTech -- are convinced that their device can be effective in detecting anomalies in the colon, and potentially the lungs or the liver.

Company spokesman Tommy Phan said IriHealth had found its device to be 81 percent accurate among patients who already have been diagnosed with colon cancer.

Hawaii's Kilauea was spraying a spectacular fountain of lava on Monday, keeping up its reputation as one of the world's most active volcanoes.

For over a year now, Kilauea has been regularly throwing out thousands of tons of molten rock and gases since it burst to life in December 2024, reported AFP.

Volcanologists with the US Geological Survey said the incandescent lava was being hurled more than 1,500 feet (460 meters) into the air, with plumes of smoke and gases rising as high as 20,000 feet (six kilometers).

Eruptions such as this one tend to last around one day, the USGS said, but can still vent up to 100,000 tons of sulfur dioxide.

This gas reacts in the atmosphere to create a visible haze known as vog -- volcanic smog -- which can cause respiratory and other problems.

Tiny slivers of volcanic glass, known as "Pele's hair," are also being thrown into the air.

Named after Pele, the Hawaiian goddess of volcanoes, the strands can be very sharp and can cause irritation to the skin and eyes.

The eruption poses no immediate danger to any human settlement, with the caldera having been closed to the public for almost two decades.

Kilauea has been very active since 1983 and erupts relatively regularly.

It is one of six active volcanoes located in the Hawaiian Islands, which also include Mauna Loa, the largest volcano in the world.

Kilauea is much smaller than neighboring Mauna Loa, but it is far more active and regularly wows helicopter-riding tourists who come to see its red-hot shows.
