NORWAY: With one foot braced on the helicopter’s landing skid, a veterinarian lifted his air rifle, took aim and fired a tranquilizer dart at a polar bear.
The predator bolted but soon slumped into the snowdrifts, its broad frame motionless beneath the Arctic sky.
The dramatic pursuit formed part of a pioneering research mission in Norway’s Svalbard archipelago, where scientists, for the first time, took fat tissue biopsies from polar bears to study the impact of pollutants on their health.
The expedition came at a time when the Arctic region was warming at four times the global average, putting mounting pressure on the iconic predators as their sea-ice habitat shrank.
“The idea is to show as accurately as possible how the bears live in the wild — but in a lab,” Laura Pirard, a Belgian toxicologist, told AFP.
“To do this, we take their (fatty) tissue, cut it in very thin slices and expose it to the stresses they face, in other words pollutants and stress hormones,” said Pirard, who developed the method.
Moments after the bear collapsed, the chopper circled back and landed. Researchers spilled out, boots crunching on the snow.
One knelt by the bear’s flank, cutting thin strips of fatty tissue. Another drew blood.
Each sample was sealed and labelled before the bear was fitted with a satellite collar.
Scientists said that while the study monitors all the bears, only females were tracked with GPS collars as their necks are smaller than their heads — unlike males, who cannot keep a collar on for more than a few minutes.
For the scientists aboard the Norwegian Polar Institute’s research vessel Kronprins Haakon, these fleeting encounters were the culmination of months of planning and decades of Arctic fieldwork.
In a makeshift lab on the icebreaker, samples remained usable for several days, subjected to controlled doses of pollutants and hormones before being frozen for further analysis back on land.
Each tissue fragment gave Pirard and her colleagues insight into the health of an animal that spent much of its life on sea ice.
Analysis of the fat samples showed that the main pollutants present were per- and polyfluoroalkyl substances (PFAS) — synthetic chemicals used in industry and consumer goods that linger in the environment for decades.
Despite years of exposure, Svalbard’s polar bears showed no signs of emaciation or ill health, according to the team.
The local population has remained stable or even increased slightly, unlike parts of Canada, where the Western Hudson Bay group declined by 27 percent between 2016 and 2021, from 842 to 618 bears, according to a government aerial survey.
Other populations in the Canadian Arctic, including the Southern Beaufort Sea, have also shown long-term declines linked to reduced prey access and longer ice-free seasons.
Scientists estimate there are around 300 polar bears in the Svalbard archipelago and roughly 2,000 in the broader region stretching from the North Pole to the Barents Sea.
The team found no direct link between sea ice loss and higher concentrations of pollutants in Svalbard’s bears. Instead, differences in pollutant levels came down to the bears’ diet.
Two types of bears — sedentary and pelagic — feed on different prey, leading to different chemicals building up in their bodies.
With reduced sea ice, the bears’ diets have already started shifting, researchers said. These behavioral adaptations appeared to help maintain the population’s health.
“They still hunt seals but they also take reindeer (and) eggs. They even eat grass (seaweed), even though that has no energy for them,” Jon Aars, the head of the Svalbard polar bear program, told AFP.
“If they have very little sea ice, they necessarily need to be on land,” he said, adding that they spend “much more time on land than they used to... 20 or 30 years ago.”
This season alone, Aars and his team of marine toxicologists and spatial behavior experts captured 53 bears, fitted 17 satellite collars, and tracked 10 mothers with cubs or yearlings.
“We had a good season,” Aars said.
The team’s innovations go beyond biopsies. Last year, they attached small “health log” cylinders to five females, recording their pulse and temperature.
Combined with GPS data, the devices offer a detailed record of how the bears roam, how they rest and what they endure.
Polar bears were once hunted freely across Svalbard but since an international protection agreement in 1976, the population here has slowly recovered.
The team’s findings may help explain how the bears’ world is changing, and at an alarming rate.
As the light faded and the icebreaker’s engines hummed against the vast silence, the team packed away their tools, leaving the Arctic wilderness to its inhabitants.

French prisoner who escaped in inmate’s bag detained
LYON: A 20-year-old French prisoner who escaped last week in the luggage of his fellow inmate when he was released was arrested Monday near the eastern city of Lyon, prosecutors said.
The man was arrested while emerging from a cellar early on Monday in Corbas near Lyon, they said, adding that his fellow prisoner accomplice had not yet been arrested.
The prisoner escaped on Friday. He was serving time for murder as part of a criminal gang and breaching a weapons law.
Princess of Wales hands out trophy to Jannik Sinner after Wimbledon final against Carlos Alcaraz
- Kate is the patron of the All England Club and presented the winner’s trophy to Sinner after he beat Alcaraz 4-6, 6-4, 6-4, 6-4 on Center Court
LONDON: Kate, the Princess of Wales, returned to Wimbledon on Sunday along with her husband Prince William and two of their children to watch the men’s final between Carlos Alcaraz and Jannik Sinner.
Kate is the patron of the All England Club and presented the winner’s trophy to Sinner after he beat Alcaraz 4-6, 6-4, 6-4, 6-4 on Center Court. The princess has been gradually resuming her public duties following cancer treatment and was at Wimbledon for a second straight day. On Saturday, she attended the women’s final and gave champion Iga Swiatek her prize after a 6-0, 6-0 victory and offered consoling words to runner-up Amanda Anisimova.
On Sunday the British royals were joined by King Felipe VI of Spain, a number of former Wimbledon champions and a slew of Hollywood celebrities.
Actors Keira Knightley, Matthew McConaughey, Nicole Kidman and John Lithgow were all seated in the Royal Box, as was London Mayor Sadiq Khan.
William and Kate arrived at the All England Club together with their oldest son, Prince George, and daughter Princess Charlotte. Before the men’s final, they spent some time chatting with Julian Cash and Lloyd Glasspool, who on Saturday became the first all-British duo in 89 years to win the men’s doubles title at Wimbledon.
Last year, while recovering from cancer, Kate did not attend the women’s final but was on hand for Alcaraz’s win against Novak Djokovic at the All England Club.
This week she also welcomed French President Emmanuel Macron during a state visit to Britain.
Gisele Pelicot and Pharrell Williams get France’s top honor
- Gisele Pelicot, who became a feminist icon by publicly testifying over the mass rapes she endured
- Rapper-turned-fashion designer Pharrell Williams were among 589 people awarded France’s top civic honor on Sunday
PARIS: Gisele Pelicot, who became a feminist icon by publicly testifying over the mass rapes she endured, and rapper-turned-fashion designer Pharrell Williams were among 589 people awarded France’s top civic honor on Sunday.
Pelicot, 72, and Williams were both named knights of the Legion of Honour on a list announced ahead of France’s July 14 national day.
Pelicot earned international tributes for her courage in testifying at a trial in 2024 against her former husband, who drugged her and arranged for her to be raped by dozens of men over a decade.
She has since been named on lists of the world’s most influential people by international media and the case helped forced a change in France’s rape law.
But Pelicot has remained silent since the trial. Her lawyer says she is concentrating on writing a book giving her side of the mass rape story which is to be released in 2026.
Williams, 52, made his name as a rapper and singer but earned a second fortune as a music producer and after designing clothes and accessories for several brands. He has been Louis Vuitton’s men’s creative director since 2023.
His recent Paris show attracted a host of international celebrities, including Jay Z and Beyonce, film directors Steve McQueen and Spike Lee and football and basketball stars.
Actor Lea Drucker, veteran singer Sylvie Vartan, writer Marc Levy and Auschwitz deportee Yvette Levy, 99, were also among the figures awarded the Legion of Honour along with a host of former ministers, academics and top legal names.
Hungary’s oldest library is fighting to save 100,000 books from a beetle infestation
- The 1,000-year-old Pannonhalma Archabbey is a sprawling Benedictine monastery that is one of Hungary’s oldest centers of learning and a UNESCO World Heritage site
PANNONHALMA, Hungary: Tens of thousands of centuries-old books are being pulled from the shelves of a medieval abbey in Hungary in an effort to save them from a beetle infestation that could wipe out centuries of history.
The 1,000-year-old Pannonhalma Archabbey is a sprawling Benedictine monastery that is one of Hungary’s oldest centers of learning and a UNESCO World Heritage site.
Restoration workers are removing about 100,000 handbound books from their shelves and carefully placing them in crates, the start of a disinfection process that aims to kill the tiny beetles burrowed into them.
The drugstore beetle, also known as the bread beetle, is often found among dried foodstuffs like grains, flour and spices. But they also are attracted to the gelatin and starch-based adhesives found in books.
They have been found in a section of the library housing around a quarter of the abbey’s 400,000 volumes.
“This is an advanced insect infestation which has been detected in several parts of the library, so the entire collection is classified as infected and must be treated all at the same time,” said Zsófia Edit Hajjdu, the chief restorer on the project. “We’ve never encountered such a degree of infection before.”
Abbey houses historical treasures
The beetle invasion was first detected during a routine library cleaning. Employees noticed unusual layers of dust on the shelves and then saw that holes had been burrowed into some of the book spines. Upon opening the volumes, burrow holes could be seen in the paper where the beetles chewed through.
The abbey at Pannonhalma was founded in 996, four years before the establishment of the Hungarian Kingdom. Sitting upon a tall hill in northwestern Hungary, the abbey houses the country’s oldest collection of books, as well as many of its earliest and most important written records.
For over 1,000 years, the abbey has been among the most prominent religious and cultural sites in Hungary and all of Central Europe, surviving centuries of wars and foreign incursions such as the Ottoman invasion and occupation of Hungary in the 16th century.
Ilona Asvanyi, director of the Pannonhalma Archabbey library, said she is “humbled” by the historical and cultural treasures the collection holds whenever she enters.
“It is dizzying to think that there was a library here a thousand years ago, and that we are the keepers of the first book catalogue in Hungary,” she said.
Among the library’s most outstanding works are 19 codices, including a complete Bible from the 13th century. It also houses several hundred manuscripts predating the invention of the printing press in the mid-15th century and tens of thousands of books from the 16th century.
While the oldest and rarest prints and books are stored separately and have not been infected, Asvanyi said any damage to the collection represents a blow to cultural, historical and religious heritage.
“When I see a book chewed up by a beetle or infected in any other way, I feel that no matter how many copies are published and how replaceable the book is, a piece of culture has been lost,” she said.
Books will spend weeks in an oxygen-free environment
To kill the beetles, the crates of books are being placed into tall, hermetically sealed plastic sacks from which all oxygen is removed. After six weeks in the pure nitrogen environment, the abbey hopes all the beetles will be destroyed.
Before being reshelved, each book will be individually inspected and vacuumed. Any book damaged by the pests will be set aside for later restoration work.
Climate change may have contributed
The abbey, which hopes to reopen the library at the beginning of next year, believes the effects of climate change played a role in spurring the beetle infestation as average temperatures rise rapidly in Hungary.
Hajjdu, the chief restorer, said higher temperatures have allowed the beetles to undergo several more development cycles annually than they could in cooler weather.
“Higher temperatures are favorable for the life of insects,” she said. “So far we’ve mostly dealt with mold damage in both depositories and in open collections. But now I think more and more insect infestations will appear due to global warming.”
The library’s director said life in a Benedictine abbey is governed by a set of rules in use for nearly 15 centuries, a code that obliges them to do everything possible to save its vast collection.
“It says in the Rule of Saint Benedict that all the property of the monastery should be considered as of the same value as the sacred vessel of the altar,” Asvanyi said. “I feel the responsibility of what this preservation and conservation really means.”
The biggest piece of Mars on Earth is going up for auction in New York
- The natural history-themed sale on Wednesday features a 54-pound hunk of Mars estimated at $2 million to $4 million
NEW YORK: For sale: A 54-pound (25-kilogram) rock. Estimated auction price: $2 million to $4 million. Why so expensive? It’s the largest piece of Mars ever found on Earth.
Sotheby’s in New York will be auctioning what’s known as NWA 16788 on Wednesday as part of a natural history-themed sale that also includes a juvenile Ceratosaurus dinosaur skeleton that’s more than 6 feet (2 meters) tall and nearly 11 feet (3 meters) long.
According to the auction house, the meteorite is believed to have been blown off the surface of Mars by a massive asteroid strike before traveling 140 million miles (225 million kilometers) to Earth, where it crashed into the Sahara. A meteorite hunter found it in Niger in November 2023, Sotheby’s says.
The red, brown and gray hunk is about 70 percent larger than the next largest piece of Mars found on Earth and represents nearly 7 percent of all the Martian material currently on this planet, Sotheby’s says. It measures nearly 15 inches by 11 inches by 6 inches (375 millimeters by 279 millimeters by 152 millimeters).
“This Martian meteorite is the largest piece of Mars we have ever found by a long shot,” Cassandra Hatton, vice chairman for science and natural history at Sotheby’s, said in an interview. “So it’s more than double the size of what we previously thought was the largest piece of Mars.”
It is also a rare find. There are only 400 Martian meteorites out of the more than 77,000 officially recognized meteorites found on Earth, Sotheby’s says.
Hatton said a small piece of the red planet remnant was removed and sent to a specialized lab that confirmed it is from Mars. It was compared with the distinct chemical composition of Martian meteorites discovered during the Viking space probe that landed on Mars in 1976, she said.
The examination found that it is an “olivine-microgabbroic shergottite,” a type of Martian rock formed from the slow cooling of Martian magma. It has a course-grained texture and contains the minerals pyroxene and olivine, Sotheby’s says.
It also has a glassy surface, likely due to the high heat that burned it when it fell through Earth’s atmosphere, Hatton said. “So that was their first clue that this wasn’t just some big rock on the ground,” she said.
The meteorite previously was on exhibit at the Italian Space Agency in Rome. Sotheby’s did not disclose the owner.
It’s not clear exactly when the meteorite hit Earth, but testing shows it probably happened in recent years, Sotheby’s said.
The juvenile Ceratosaurus nasicornis skeleton was found in 1996 near Laramie, Wyoming, at Bone Cabin Quarry, a gold mine for dinosaur bones. Specialists assembled nearly 140 fossil bones with some sculpted materials to recreate the skeleton and mounted it so it’s ready to exhibit, Sotheby’s says.
The skeleton is believed to be from the late Jurassic period, about 150 million years ago, Sotheby’s says. It’s auction estimate is $4 million to $6 million.
Ceratosaurus dinosaurs were bipeds with short arms that appear similar to the Tyrannosaurus rex, but smaller. Ceratosaurus dinosaurs could grow up to 25 feet (7.6 meters) long, while the Tyrannosaurs rex could be 40 feet (12 meters) long.
The skeleton was acquired last year by Fossilogic, a Utah-based fossil preparation and mounting company.
Wednesday’s auction is part of Sotheby’s Geek Week 2025 and features 122 items, including other meteorites, fossils and gem-quality minerals.
