Changing Guard at Buckingham Palace: Camilla Steps Up

A gradual changing of the guard is happening at the head of Britain's royal family, as Queen Elizabeth II steps back from public engagements due to her advanced age and health.

The 95-year-old monarch's eldest son and heir, Charles, Prince of Wales, has been shouldering more of the burden of official duties for several years, including overseas.

But his wife, Camilla, is increasingly stepping into the fray, both online during coronavirus pandemic restrictions in the past year and now in person, after curbs were lifted.

Joining the couple at the royal vanguard are Charles' eldest son from his first marriage to Princess Diana, William, and his wife, Kate.

As a result, they have earned a greater share of the media coverage that would previously have gone to the monarch, who has been advised to rest by doctors.

Their presence at events -- from the world premiere of the latest James Bond film to meeting world leaders at the G7 and UN climate summits -- is a clear sign of change to come.

Joe Little, managing editor of Majesty Magazine, told AFP their visibility "will accelerate within the fullness of time".

"But a lot of people are now familiar with Camilla and are getting to know her," he added.

- Rehabilitation -
Camilla, 74, also known as the Duchess of Cornwall, will become consort when Charles, 72, takes the throne. William, 39, will move up the line of succession to heir apparent.

Only a few years ago, a different "Fab Four" were seen as the future of Britain's most famous family: William and Kate along with his younger brother Harry and his wife Meghan.

But plans changed dramatically last year when Harry and Meghan moved to the United States, from where they have criticized the family and even accused it of racism.

The rise of Camilla -- once a hate-figure for being "the other woman" in Charles and Diana's marriage -- has been remarkable.

"Her position has certainly evolved and there's been a huge and very long process of rehabilitation since... she was described as this rottweiler at the time of Diana," royal historian Anna Whitelock told the Daily Express.

Camilla, like other royals, was forced into a more public role by the coronavirus pandemic, when the world moved online.

But she has taken on the role with aplomb and won fans, even if in the eyes of some she can never be forgiven for her role in the collapse of Charles and Diana's marriage.

"There are lots of Camilla supporters out there," said Little.

"The sense is she's coping with it very well. She's been a member of the royal family for 16 years, so she's had quite a bit of experience of high-profile things...

"She's become very proficient at it."

Since the death of the Queen's husband of 73 years, Prince Philip, in April, Camilla has been seen -- and heard -- more frequently at official royal engagements and charity events.

This week she accompanied Charles -- a longstanding environmentalist -- to the UN COP26 summit in Glasgow, to urge world leaders to stop runaway climate change.

Last month she and Charles, who married in 2005, supported the Queen at the official opening of the Scottish Parliament in Edinburgh and the Welsh Assembly in Cardiff.

She was also present as the monarch undertook her first ceremonial engagement since her husband's death -- the State Opening of Parliament in May.

In the coming weeks, the couple embark on the first royal overseas tour since the start of the coronavirus pandemic, visiting Egypt, which will host COP27, and Jordan.

- Bigger role? -
Camilla's appearances elsewhere reflect her variety of interests, from promoting literacy via her popular Instagram book club to championing rescue animals.

She gave a well-received speech and backing to a campaign tackling violence against women, dovetailing with support given by Kate to the issue earlier this year.

Camilla has also made several television and radio appearances, speaking about her mother's battle with osteoporosis and her love of gardening and horse breeding.

Reports said she could soon take on a bigger role as one of the "counsellors of state", a group of senior royals appointed to step in if the Queen cannot perform her official duties.

Speculation has mounted because the other counsellors alongside Charles and William -- Prince Andrew and Harry -- are no longer serving royals.

"The Queen may look to add the Duchess of Cornwall, who would become a counsellor of state when Charles is king anyway," constitutional expert Craig Prescott from Bangor University told the Mail on Sunday.

Sharks Are Famous for Fearsome Teeth, but Ocean Acidification Could Make them Weaker

Sharks are the most feared predators in the sea, and their survival hinges on fearsome teeth that regrow throughout their lives. But changes in the ocean's chemistry could put those weapons at risk.

That is the takeaway from a study performed by a group of German scientists who tested the effects of a more acidic ocean on sharks' teeth. Scientists have linked human activities including the burning of coal, oil and gas to the ongoing acidification of the ocean, The Associated Press reported.

As oceans become increasingly acidic, sharks' teeth could become structurally weaker and more likely to break, the scientists found. That could change the big fishes' status at the top of the ocean's food chain, they wrote.

The ocean will not become populated with toothless sharks overnight, said the study's lead author, Maximilian Baum, a marine biologist at Heinrich Heine University Düsseldorf. But the possibility of weaker teeth is a new hazard to sharks that already face pollution, overfishing, climate change and other threats, Baum said.

“We found there is a corrosion effect on sharks' teeth,” Baum said. “Their whole ecological success in the ocean as the rulers of other populations could be in danger.”

The researchers, who published their work in the journal Frontiers in Marine Science, performed their study as ocean acidification has become an increasing focus of conservation scientists.

Acidification occurs when oceans absorb more carbon dioxide from the air, the National Oceanic and Atmospheric Administration has said. The ocean is expected to become almost 10 times more acidic than it currently is by the year 2300, the German scientists wrote.

The scientists performed their study by collecting more than 600 discarded teeth from an aquarium that houses blacktip reef sharks, a species of shark that lives in the Pacific and Indian oceans and typically grows to about 5.5 feet (1.7 meters) long. They then exposed the teeth to water with the acidity of today and the projected acidity of 2300.

The teeth exposed to the more acidic water became much more damaged, with cracks and holes, root corrosion and degradation to the structure of the tooth itself, the scientists wrote.

The results “show that ocean acidification will have significant effects on the morphological properties of teeth,” the scientists wrote.

Still the ocean's top predator Shark teeth are “highly developed weapons built for cutting flesh, not resisting ocean acid,” Baum said. Sharks will go through thousands of teeth in a lifetime, and the teeth are critical for allowing sharks to regulate populations of fish and marine mammals in the oceans.

Many sharks are also facing extinction jeopardy, as more than a third of shark species are currently threatened with extinction according to the International Union for Conservation of Nature. Thankfully, sharks have a number of factors that can help them stave off the negative effects of ocean acidification, said Nick Whitney, senior scientist at the Anderson Cabot Center for Ocean Life at the New England Aquarium.

Whitney, who was not involved in the study, said the scientists' work on the shark teeth was sound. However, because shark teeth develop inside the mouth tissue of sharks, they will be shielded from changes in ocean chemistry for a time, he said.

And history has taught us that sharks are survivors, Whitney said.

“They've been around for 400 million years and have evolved and adapted to all kinds of changing conditions,” he said.

Ocean acidification could be a concern, but overfishing remains the biggest threat to sharks, said Gavin Naylor, director of the Florida Program for Shark Research at the Florida Museum of Natural History.

Acidification will bring many changes Naylor and others cautioned that ocean acidification is indeed going to pose many threats to the ocean beyond just sharks. Ocean acidification is expected to be especially harmful to shellfish such as oysters and clams because it will make it more difficult for them to build shells, NOAA has said.

It could also make fish scales weaker and more brittle. It's tough to say now whether that could ultimately benefit the sharks that feed on them, Naylor said.

For now, ocean acidification can't be disregarded as a threat facing sharks, Baum said. Some shark species could come close to extinction in the coming years and ocean acidification could be one of the factors causing that to happen, he said.

“The evolutionary success of sharks is dependent on their perfectly developed teeth,” Baum said.

Scientists have uncovered the mummified remains of cheetahs from caves in northern Saudi Arabia.

The remains range from 130 years old to over 1,800 years old. Researchers excavated seven mummies along with the bones of 54 other cheetahs from a site near the city of Arar.

Mummification prevents decay by preserving dead bodies. Egypt's mummies are the most well-known, but the process can also happen naturally in places like glacier ice, desert sands and bog sludge.

The new large cat mummies have cloudy eyes and shriveled limbs, resembling dried-out husks.

“It’s something that I’ve never seen before,” said Joan Madurell-Malapeira with the University of Florence in Italy, who was not involved with the discovery.

Researchers aren’t sure how exactly these new cats got mummified, but the caves’ dry conditions and stable temperature could have played a role, according to the new study published Thursday in the journal Communications Earth and Environment.

They also don't know why so many cheetahs were in the caves. It could have been a denning site where mothers birthed and raised their young.

Scientists have uncovered the rare mummified remains of other large cats, including a saber-toothed cat cub in Russia.

It's uncommon for large mammals to be preserved to this degree. Besides being in the right environment, the carcasses also have to avoid becoming a snack for hungry scavengers like birds and hyenas.

Cheetahs once roamed across most of Africa and parts of Asia, but now live in just 9% of their previous range and haven't been spotted across the Arabian Peninsula for decades. That’s likely due to habitat loss, unregulated hunting and lack of prey, among other factors.

In a first for naturally mummified large cats, scientists were also able to peek at the cheetahs' genes and found that the remains were most similar to modern-day cheetahs from Asia and northwest Africa. That information could help with future efforts to reintroduce the cats to places they no longer live.

Lindsey Vonn may be dominating World Cup downhills at 41, but even the US speed queen is not immune to missing equipment.

Vonn took to social media on Thursday with an unusual plea after losing a ski pole in Tarvisio, Italy, ahead of this weekend's World Cup event.

"Someone took ‌my pole ‌in the parking ‌lot ⁠today in ‌Tarvisio. If you have seen it, please respond to this. Thank you," Vonn wrote on X, posting a photo of the matching pole complete with her initials on the ⁠hand strap.

Vonn, a favorite for the speed events ‌at next month's Milano-Cortina ‍Olympics, retired ‍from the sport in 2019 and ‍had a partial knee replacement in April 2024 but returned to competition later that year and has been enjoying a fairy-tale comeback that has defied age and expectation.

Already the oldest ⁠World Cup winner of all time, Vonn continued her astonishing, age-defying form with a downhill victory in Zauchensee, Austria last week.

That triumph marked Vonn's fourth podium from four downhills this season, cementing her lead in the World Cup standings and her status as the woman to ‌beat at next month's Olympics.
