Do you know the highest average grossing movie franchise in history? That’s easy, “Avatar.” What about the record for the most balloons popped in one minute by a pogostick? Or the longest journey in a pumpkin boat?

These and many more superlatives are in the latest edition of the Guinness World Records, which for 2024’s edition has taken our watery world as its theme. That means there’s extra entries for aquatic record-breakers, the largest octopuses, largest hot spring and deepest shark among the 2,638 achievements.

“To me the best records are the ones that you tell your friends in the playground or your mates, or wherever it is, in the gym. You just say ‘Look I saw this amazing thing today.’ That to me, is the sign of a good record,” says Editor-in-Chief Craig Glenday.

He estimates that 75% to 80% of the entries are new and updated, reflecting a huge oversupply of content. The Guinness World Record researchers get many more records approved than they can fit in a single book.

This year’s book is balanced between zany items — most hula hoops spun simultaneously on stilts — to serious science, like heaviest starfish. There are visits to history — pirate ships and shipwrecks — and pages devoted to record-breakers, like musician Elton John and tennis player Shingo Kunieda.

There’s a whole series of records just for kids and a new impairment initiative, which gives people with physical and mental challenges the chance to break records within their communities. It is all cleverly packed with facts, drawings and images and puzzles.

Glenday sees the annual book — initially conceived to settle bar arguments — as a fundamentally optimistic collection, one that celebrates ambition and record-breaking as very human things.

“We’re all striving to be a bit better at what we do and we enjoy the bit between life and death. So let’s just make the most of it. And I think that’s why it’s maintained its position over the last 70 years — it continues to just amuse and educate and inform and celebrate all these crazy, fun, inspiring things and people.”

The team at Guinness World Records get about 100 applicants a day and reject some 95%. Submissions, on the whole, must be measurable, breakable and provable. They may not impinge on someone else’s human rights or hurt an animal. And each book is curated annually, so twerking records, a thing just a few years ago, get replaced by TikTok records.

“We want things to be officially amazing. So is it amazing? Everything is a record. I could say I had couscous for lunch and I could document it, but no one cares. Where’s the superlative in it?”

Rejections are done diplomatically. If, for instance, an applicant hopes to land the record for most pretzels stuffed in their nose, researchers might gently say no, but prod the applicant to the grape-stuffing section. “If stuffing is your thing, we might have a category already created for you.”

First published in 1955, the book has developed into an international phenomenon published in more than 100 countries and 37 languages. The publication itself is listed as the world’s best-selling copyrighted book.

“It’s really aimed at reluctant readers. It’s lots of little chunks and trivia and nuggets. The designers agonize over every spread and they start from scratch every year. We throw the whole thing away in terms of the design,” says Glenday.

It started when Sir Hugh Beaver, then managing director of the Guinness Brewery, was invited to go game bird hunting in Ireland. He and his companions soon began to squabble over which was Europe’s fastest game bird. There was no quick way to solve the dispute.

“He said, ‘There must be in pubs all around the country people fighting and arguing over things that are simple and yet they can’t find an answer,’” Glenday says. Beaver dreamed up a pamphlet that could be sold to pubs alongside barrels of Guinness Stout.

He asked twins Norris and Ross McWhirter, who were fact-finding researchers, to compile something that would be different from the day’s encyclopedias, which were dry and very highly academic.

“What these guys did was create a book that says, ‘We’re going to reflect back what people are actually doing in the world.’ And so what they inadvertently created was an annual snapshot of the world.”

“It found this momentum, this life of its own, and took off and became much more than Sir Hugh ever imagined it could be because it was a unique way of thinking about the world.”

Glenday himself has been inspired to create categories. A few years ago, he was attending the X Games and saw a bulldog zip past him on a skateboard in the parking lot.

He found the owner of the dog, asked if he could chalk off 100 meters and invited the dog to skate. “We created a brand new record that became a thing, skateboarding dogs.”

“I’m fascinated just by the quirky and unusual and the slightly skewed view that Guinness World Records has on the world, so it’s been a perfect fit.”

He believes everyone has a record in them, whether it’s most sweaters worn, the loudest burp or baking the largest cake pop. And just striving for the record is rewarding, too.

“It’s very difficult to climb K2 in the fastest time. It’s very difficult and it will cost a fortune and you need years probably of training and acclimatization for weeks,” he says.

“But if you’re stuck at home with your kids and you think, ‘Let’s see how fast we can solve Mr. Potato Head,’ then you’ve got some bonding time with your child just trying to do Mr. Potato Head at the fastest time.”

One record is always up for the taking no matter who you are: oldest human. “Anyone can attempt the oldest age. I mean, that’s what we’re all attempting,” he says, laughing.



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.
