Norwegian polar bears thrive despite ice loss, study finds
Researchers believe that a shift in the diet of Svalbard bears, towards increased consumption of terrestrial prey, may be an adaptation to the recent decline in sea ice.
In a surprising turn of events, polar bears in the Norwegian Arctic's Svalbard archipelago have experienced improved health and increased body fat since the early 1990s, despite the steady decline of sea ice due to climate change.
The primary source of nutrition for polar bears is seals, which they hunt from the platform of sea ice. The bears' fat reserves are crucial for energy, insulation, and nursing their cubs, as they provide the necessary nutrients for the young to thrive.
A study conducted between 1992 and 2019, which involved weighing and measuring 770 adult polar bears in Svalbard, revealed a significant increase in the bears' body fat.
Researchers believe that the polar bears in Svalbard have adapted to the loss of sea ice by expanding their diet to include land-based prey, such as reindeer and walruses, which has helped them to maintain their weight and overall health.
The findings, published in Scientific Reports, are particularly noteworthy given the significant impact of climate change on the Svalbard region.

Over the course of the study, the number of ice-free days in the region increased by nearly 100, at a rate of approximately four days per year, due to rising global temperatures.
According to Dr Jon Aars, the lead researcher from the Norwegian Polar Institute, "A bear's fat reserves are a key indicator of its overall health, and in this case, the bears have become significantly fatter."
Dr Aars expressed surprise at the findings, stating that he would have expected the loss of sea ice to have a negative impact on the bears' body condition.
In Norway, walruses have been protected by law since the 1950s, after being hunted to near extinction. This protection has led to an increase in their population, providing a new source of food for polar bears.

Dr Aars noted that the increased presence of walruses in the region has likely contributed to the bears' improved diet, and also suggested that the bears may have become more efficient hunters of seals.
The researcher explained that as sea ice declines, seals are forced to congregate in smaller areas, making it easier for bears to hunt them.
Although this discovery is a positive development for polar bears in the short term, researchers believe that it is unlikely to be sustainable in the long term.

As sea ice continues to decline, polar bears will be forced to travel further to reach their hunting grounds, expending more energy and depleting their fat reserves.
The charity Polar Bears International notes that Svalbard's polar bears were heavily hunted until international protections were introduced in the 1970s.
Experts suggest that the recent findings may be linked to the population's recovery from historical hunting pressures, combined with the increased availability of walruses and reindeer in the region.
Dr John Whiteman, chief research scientist at Polar Bears International, described the results as "positive in the short term".

However, Dr Whiteman cautioned that the overall health of the polar bear population is complex and multifaceted, citing recent research that found a decline in cub survival and increased mortality among subadult and older female bears in areas with more ice-free days.
The impact of climate change on polar bears varies significantly across different regions of the Arctic.
There are 20 known sub-populations of polar bears worldwide, each facing unique challenges and circumstances.
In Canada's Western Hudson Bay, home to one of the most well-studied polar bear populations, a decline in the population has been directly linked to rising temperatures.
Dr Whiteman emphasized that the long-term survival of polar bears is inextricably linked to the availability of sea ice, and that the current trends are clear: polar bears need sea ice to survive.
"While the short-term picture may vary by region, the ultimate consequence of ice loss is a decline in polar bear populations," Dr Whiteman noted.
In the long term, Dr Whiteman warned that if ice loss continues unchecked, polar bears will eventually disappear, highlighting the urgent need for conservation efforts to protect these iconic creatures.

Water Leak Affects 19th Century Artwork at Louvre Museum
The world’s most visited museum has been marred by a series of incidents, prompting growing scrutiny of its management.
The Louvre museum in Paris has experienced a significant setback due to a water leak that damaged a 19th-century ceiling painting, marking the latest in a series of challenges for the institution.

According to the museum, the water damage was discovered in room 707, also known as the "Duchâtel" room, on Thursday evening, with the room housing various artworks from the 15th and 16th centuries.
The leak, which originated from a heating pipe, was reportedly stopped shortly after midnight, and the only artwork damaged was Charles Meynier's The Apotheosis of Poussin, Le Sueur and Le Brun, a ceiling painting.
This incident occurred just a day after French authorities detained nine individuals, including two museum staff members, in connection with an alleged ticket fraud scheme.
In recent months, the museum's management has faced increased scrutiny following a string of high-profile incidents, including the theft of French crown jewels and damage to hundreds of books due to a leak.
The Louvre reported that Thursday's leak occurred near the entrance to the paintings department in the Denon wing of the museum.
Firefighters responded promptly to the incident, and the leak was brought under control within 40 minutes of its discovery.
On Friday morning, a painting restorer assessed the damage to Meynier's ceiling painting and found that it had sustained two tears in the same area, as well as lifting of the paint layer on the ceiling and its arches.
The damaged ceiling painting, which dates back to 1822 and is signed by Meynier, depicts renowned French painters Nicolas Poussin, Eustache Le Sueur, and Charles Le Brun surrounded by angelic figures in the clouds.
As a precautionary measure, rooms 706, 707, and 708 in the Denon wing were closed on Friday morning but are expected to reopen later in the day.
The chief architect of historic monuments visited the site to evaluate the condition of the ceiling and determined that there were no structural issues.
A union representative informed Reuters that scaffolding had been erected in the affected area to facilitate repairs.
The extent of the damage to the painting and the building, as well as the associated costs, have not been disclosed.
This latest incident is part of a series of challenges faced by the Louvre, which is the most visited museum globally, in recent times.
In December, a leak in the Egyptian department damaged between 300 and 400 items, mostly books, with the museum's deputy administrator, Francis Steinbock, acknowledging that the issue had been known for years.
The previous month, the museum had to partially close one of its galleries featuring Greek vases and offices due to structural weaknesses.
This incident followed a high-profile burglary on October 19, in which four individuals stole historic jewelry valued at €88 million, exposing significant security gaps at the museum.
The thieves used a stolen vehicle-mounted mechanical lift to gain access to the Galerie d'Apollon via a balcony overlooking the River Seine.
Several individuals have been arrested in connection with the theft, which is still being investigated by the French authorities.
The majority of the stolen items remain unrecovered, and the museum has since relocated some of its most valuable jewels to the Bank of France for safekeeping.
A report published by France's public audit body in October criticized the museum's excessive spending on artwork, stating that it had come at the expense of building maintenance and renovation.

Russell Describes Red Bull’s Advantage as Highly Intimidating
Mercedes driver George Russell notes that Red Bull’s lead at the forefront of the Formula 1 pack has been particularly noteworthy, revealing a significant gap that has caught the attention of many in the sport.
As George Russell enters his fifth season with Mercedes, the team is gearing up for a new challenge in the 2026 Formula 1 season.
According to Mercedes driver George Russell, Red Bull's current advantage at the front of the pack is a significant concern, with the team's performance in the first pre-season test at Bahrain being particularly noteworthy.
Russell described the display of speed by Red Bull in Bahrain as a "wake-up call" for their competitors, highlighting the team's impressive pace in the first of two pre-season tests.
The British driver noted that Red Bull's lead is substantial, with a gap of around half a second to a full second per lap, which is a considerable margin in the context of Formula 1.
Russell expressed his surprise at the scale of Red Bull's advantage, stating that it is unsettling to see such a significant difference in performance, especially given Red Bull's history of producing competitive cars, even when their engine was not the strongest.
The 2026 season marks the most significant rule change in Formula 1 history, with new specifications for engines, chassis, tires, and fuel, which promises to shake up the competitive landscape.
As a result of these changes, energy management has become a critical aspect of the sport, with engines now producing approximately half of their total power output from the electrical component, and limited battery capacity.
Rivals have analyzed GPS data from Red Bull's power unit during the Bahrain test, revealing that the team can sustain electrical energy deployment for longer periods than any of their competitors.
This achievement is all the more impressive considering that Red Bull has established its own engine company from scratch to comply with the new regulations and has partnered with Ford.
Last season, Max Verstappen narrowly missed out on the drivers' title, finishing just two points behind Lando Norris.
Russell stated that his team had observed Red Bull's strength from the outset of the 'shakedown' test in Spain last month, and their performance has been consistently impressive.
He noted that on the first day of testing in Barcelona, Red Bull immediately demonstrated a significant advantage over their competitors, including Mercedes, Ferrari, and others.
Russell acknowledged that Red Bull's performance in Bahrain has further solidified their position as the team to beat, at least for the time being.
Looking ahead to the first race of the season in Melbourne, Russell predicts that Red Bull will likely maintain their advantage, given their strong showing in both Barcelona and Bahrain.
However, Red Bull technical director Pierre Wache has downplayed Mercedes' claims, suggesting that his team is not the benchmark, and instead, Ferrari, Mercedes, and McLaren are currently ahead.
Wache argued that Red Bull's analysis indicates they are behind the top three teams, contrary to the assertions made by Mercedes team principal Toto Wolff.
Ferrari driver Charles Leclerc believes that Mercedes is concealing their true potential and that Red Bull and Mercedes have posted the fastest times, followed closely by his own team.
The new cars have sparked a debate among drivers, with some enjoying the updated handling and ride, while others have expressed reservations about the changes.
On the second day of testing, Lando Norris and Max Verstappen disagreed on whether the new cars are enjoyable to drive, reflecting the mixed opinions among drivers.
Russell described the 2026 cars as "much nicer to drive" in terms of handling and ride compared to the previous season's cars, but noted that the engines are highly complex.
He cautioned against drawing conclusions too early, as the true challenges of the new engines and energy management systems will only become apparent at more demanding tracks like Melbourne or Jeddah.
Russell elaborated on a point made by Verstappen regarding the unusual driving styles required by the new engines, which demand careful management of energy recovery.
Drivers are having to adapt to unconventional techniques, such as using lower gears in corners to keep the engine revving and maximize energy recovery.
Russell provided an example from the Bahrain test, where he had to use first gear in a corner that would normally be taken in third gear, in order to maintain high engine revs and keep the turbo spinning.
He acknowledged that this approach can be counterintuitive and frustrating at times.
Russell used an analogy to illustrate the point, comparing it to driving a road car and being told to use first gear in a roundabout, which would be unconventional and unnecessary at normal speeds.
He emphasized that the car is not designed to handle such low gears in certain corners, but drivers are having to work around these limitations to optimize energy recovery.
Russell explained that the car's design is not suited for such low gears, but the need to maintain high engine revs and turbo boost necessitates this approach.
As a result, drivers are having to adapt their techniques to prioritize energy management over traditional notions of fast cornering.
Russell noted that the critical nature of energy levels in determining lap times means that driving around a corner in the fastest possible way may not always result in the best overall lap time.
In the past, drivers could focus on finding the quickest line through a corner, but now they need to consider the broader implications of their actions on energy levels and overall lap time.
Russell stated that drivers must now wait for a full lap to understand the impact of their decisions on energy levels, rather than being able to instantly assess the effectiveness of a particular line or technique.
Meanwhile, Aston Martin is reported to be around four seconds off the pace of the top teams, highlighting the significant gap they need to bridge to be competitive.
The 2026 Formula 1 cars have been on display in Bahrain, showcasing the new designs and technologies.
The sport has introduced new terminology, including "active aero" and "overtake mode," which reflect the changes brought about by the new regulations.
Russell has expressed his desire to compete directly with Verstappen, setting the stage for an exciting season of racing.
The 2026 season promises to be an exciting one, with the biggest rule change in Formula 1 history, a new generation of drivers, and a fresh wave of technological innovation.
