Scientists have identified an estimated 10% of all species on Earth. Here’s what they found in 2024

A toothy toadstool. A vegetarian piranha with a distinctive mark. And a pygmy pipehorse floating in the Indian Ocean shallows.

These wild wonders were among the hundreds of previously unknown species of animals, plants and fungi that scientists named and described for the first time in 2024, expanding our surprisingly limited knowledge of Earth’s diversity.

“Scientists estimate that we’ve identified only one-tenth of all species on Earth,” said Dr.
Shannon Bennett, chief of science at the California Academy of Sciences, in a statement.

“While it is critical to place protections on known threatened species, we must also allocate resources towards identifying unknown species that may be just as important to the functioning of an ecosystem,” Bennett said.

Researchers connected to the institution described 138 new species in 2024, including 32 fish. One standout was a pygmy pipehorse named Cylix nkosi. The seahorse relative was originally found in 2021 in the cool temperate waters surrounding the North Island of New Zealand, but the species described this year was discovered in the subtropical waters off South Africa, expanding the known range of this group to the Indian Ocean

“South African reefs present notoriously difficult diving conditions with rough weather and intense, choppy waves — we knew we only had one dive to find it,” underwater photographer and marine biologist Richard Smith said in a statement.
“This species is also quite cryptic, about the size of a golf tee, but luckily we spotted a female camouflaged against some sponges about a mile offshore on the sandy ocean floor.”

The researchers involved in describing the new species chose nkosi as its name. A reference to the local Zulu word for “chief,” the name reflects the species’ crown-like head shape and acknowledges South Africa’s KwaZulu-Natal province where it was found.

Most plane crashes are ‘survivable’
[url=https://kra26c.cc]kraken marketplace[/url]
First, the good news. “The vast majority of aircraft accidents are survivable, and the majority of people in accidents survive,” says Galea. Since 1988, aircraft — and the seats inside them — must be built to withstand an impact of up to 16G, or g-force up to 16 times the force of gravity. That means, he says, that in most incidents, “it’s possible to survive the trauma of the impact of the crash.”

For instance, he classes the initial Jeju Air incident as survivable — an assumed bird strike, engine loss and belly landing on the runway, without functioning landing gear. “Had it not smashed into the concrete reinforced obstacle at the end of the runway, it’s quite possible the majority, if not everyone, could have survived,” he says.

The Azerbaijan Airlines crash, on the other hand, he classes as a non-survivable accident, and calls it a “miracle” that anyone made it out alive.

Most aircraft involved in accidents, however, are not — as suspicion is growing over the Azerbaijan crash — shot out of the sky.

And with modern planes built to withstand impacts and slow the spread of fire, Galea puts the chances of surviving a “survivable” accident at at least 90%.

Instead, he says, what makes the difference between life and death in most modern accidents is how fast passengers can evacuate.

Aircraft today must show that they can be evacuated in 90 seconds in order to gain certification. But a theoretical evacuation — practiced with volunteers at the manufacturers’ premises — is very different from the reality of a panicked public onboard a jet that has just crash-landed.
Galea, an evacuation expert, has conducted research for the UK’s Civil Aviation Authority (CAA) looking at the most “survivable” seats on a plane. His landmark research, conducted over several years in the early 2000s, looked at how passengers and crew behaved during a post-crash evacuation, rather than looking at the crashes themselves. By compiling data from 1,917 passengers and 155 crew involved in 105 accidents from 1977 to 1999, his team created a database of human behavior around plane crashes.

His analysis of which exits passengers actually used “shattered many myths about aircraft evacuation,” he says. “Prior to my study, it was believed that passengers tend to use their boarding exit because it was the most familiar, and that passengers tend to go forward. My analysis of the data demonstrated that none of these myths were supported by the evidence.”

The mysterious cities of the dead carved into the sides of cliffs
kraken4qzqnoi7ogpzpzwrxk7mw53n5i56loydwiyonu4owxsh4g67yd.onion
The ancient Lycians knew a thing or two about democracy. Two thousand years ago, the one-time rulers of modern-day Turkey’s southwestern corner had a fully functioning democratic federation that centuries later inspired America’s political structure.

While democracies everywhere might be facing turbulent times, another Lycian legacy remains steadfastly present in the Mediterranean region they used to call home. And this one is focused almost entirely around death.

Drive around the coast of this beautiful region and you’ll never be too far from a spectacular city of the dead – elaborate tombs carved by Lycians into the sides of cliffs overlooking towns, valleys and shorelines.

That’s not all. Scattered throughout the countryside and towns are imposing sarcophagi that likely once held the remains of high and mighty denizens of Lycia. Indeed, they’re such a familiar sight that they’re often casually included as part of urban landscapes.

For visitors, especially those interested in history, tracking them down is an adventure all on its own.

While some are preserved in ticketed archaeological sites, others are free to explore — but can require Indiana Jones-level exploration skills, clambering up vertiginous hillsides, riding boats and delving into the undergrowth to find.
A good starting place is Fethiye, a low-key port city that’s a useful jumping-off point for great beaches and attractions all along Turkey’s so-called Turquoise Coast riviera. After a day of swimming in those glorious waters, it’s worth a sunset trek to the overlooking cliffs.

Carrie Underwood slated to perform at Trump’s inauguration
кракен вход
Country music star Carrie Underwood is slated to perform “America the Beautiful” at President-elect Donald Trump’s inauguration, according to a copy of the program obtained by CNN and confirmed by a spokesperson for the inaugural committee.

“I love our country and am honored to have been asked to sing at the Inauguration and to be a small part of this historic event,” Underwood said in a statement to CNN. “I am humbled to answer the call at a time when we must all come together in the spirit of unity and looking to the future.”

The presidential oath of office will be administered by Supreme Court Chief Justice John Roberts with Justice Brett Kavanaugh expected to administer the oath of office to Vice President-elect JD Vance.

Trump’s inauguration as the 47th president of the United States will take place on January 20 at the US Capitol.

Underwood is a big get for Trump’s inauguration, considering Hollywood’s Trump blackout over the course of his political career.

In his first term and throughout the past three elections, Trump has struggled to garner support from major Hollywood stars. At the Republican National Convention last year, the two biggest stars onstage with Trump were musician Kid Rock and retired WWE wrestler Hulk Hogan – a far cry from a superstar at the height of their career, like Underwood.

The Grammy-winning artist is as high-profile as you can get in country music, not only with numerous platinum hits, but also with public-facing, mainstream business associations. Underwood is the face of Sunday Night Football and is set to make her debut this March as a judge on ABC’s “American Idol” – the singing competition show that catapulted her to fame when she won in 2005.

While many NFL fans will likely applaud Underwood for singing at the inauguration, any time a celebrity aligns themselves with Trump, they run the risk of alienating left-leaning fans and Hollywood allies.

Underwood has kept her politics under wraps over the course of her career. In her statement, she did not mention Trump by name and kept her focus on unifying the country – still, Underwood’s decision to publicly align with Trump is a big statement for any star, particularly one as private as the singer.

Historically, Hollywood has always been closely associated with the Democratic Party, but country stars have always been an outlier, leaning more conservative. In recent years, as new singers join the genre, country music has gotten to be more progressive. This past election cycle, country stars like Mickey Guyton and Maren Morris stood with Vice President Kamala Harris.

A brief history of sunglasses, from Ancient Rome to Hollywood
[url=https://krkns.cc]kraken войти[/url]

Sunglasses, or dark glasses, have always guarded against strong sunlight, but is there more to “shades” than we think?

The pupils of our eyes are delicate and react immediately to strong lights. Protecting them against light — even the brilliance reflected off snow — is important for everyone. Himalayan mountaineers wear goggles for this exact purpose.

Protection is partly the function of sunglasses. But dark or colored lens glasses have become fashion accessories and personal signature items. Think of the vast and famous collector of sunglasses Elton John, with his pink lensed heart-shaped extravaganzas and many others.

When did this interest in protecting the eyes begin, and at what point did dark glasses become a social statement as well as physical protection?
The Roman Emperor Nero is reported as holding polished gemstones to his eyes for sun protection as he watched fighting gladiators.

We know Canadian far north Copper Inuit and Alaskan Yupik wore snow goggles of many kinds made of antlers or whalebone and with tiny horizontal slits. Wearers looked through these and they were protected against the snow’s brilliant light when hunting. At the same time the very narrow eye holes helped them to focus on their prey.

In 12th-century China, judges wore sunglasses with smoked quartz lenses to hide their facial expressions — perhaps to retain their dignity or not convey emotions.
