  1. The survivors of recent crashes were sitting at the back of the plane. What does that tell us about airplane safety?

    Look at the photos of the two fatal air crashes of the last two weeks, and amid the horror and the anguish, one thought might come to mind for frequent flyers.

    The old frequent-flyer adage is that sitting at the back of the plane is a safer place to be than at the front — and the wreckage of both Azerbaijan Airlines flight 8243 and Jeju Air flight 2216 seem to bear that out.

    The 29 survivors of the Azeri crash were all sitting at the back of the plane, which split into two, leaving the rear half largely intact. The sole survivors of the South Korean crash, meanwhile, were the two flight attendants in their jumpseats in the very tail of the plane.

    So is that old adage — and the dark humor jokes about first and business class seats being good until there’s a problem with the plane — right after all?

    In 2015, TIME Magazine reporters wrote that they had combed through the records of all US plane crashes with both fatalities and survivors from 1985 to 2000, and found in a meta-analysis that seats in the back third of the aircraft had a 32% fatality rate overall, compared with 38% in the front third and 39% in the middle third.

    Even better, they found, were middle seats in that back third of the cabin, with a 28% fatality rate. The “worst” seats were aisles in the middle third of the aircraft, with a 44% fatality rate.
    But does that still hold true in 2024?

    According to aviation safety experts, it’s an old wives’ tale.

    “There isn’t any data that shows a correlation of seating to survivability,” says Hassan Shahidi, president of the Flight Safety Foundation. “Every accident is different.”

    “If we’re talking about a fatal crash, then there is almost no difference where one sits,” says Cheng-Lung Wu, associate professor at the School of Aviation of the University of New South Wales, Sydney.

    Ed Galea, professor of fire safety engineering at London’s University of Greenwich, who has conducted landmark studies on plane crash evacuations, warns, “There is no magic safest seat.”

  2. How Austrian climber Babsi Zangerl completed a ‘hard to believe’ historic ascent of El Capitan

    On a vertical rockface like El Capitan, the soaring slab of granite in California’s Yosemite National Park, perfection is an elusive, almost impossible goal for professional climbers.

    It can take years of experience to master a route to the top of the 3,000-foot wall, such is its difficulty and magnitude. That’s precisely why Babsi Zangerl’s recent “flash” of El Cap is so unique and impressive.

    In climbing, to “flash” a route is to reach the top on the first attempt without any falls – a feat never before achieved on El Cap prior to Zangerl’s maiden summit of Freerider last month. From bottom to top, she was faultless.

    “It was hard to believe,” the Austrian climber tells CNN Sport. “I was so surprised that this just happened and that I didn’t fall … I could have fallen so many times on that climb.”
    Freerider is a popular route up El Capitan, the same one taken by Alex Honnold when he climbed the rockface without ropes or harnesses in the Oscar-winning documentary “Free Solo.”

    Zangerl has lots of experience climbing on El Cap and around Yosemite but had never previously attempted the 30-plus pitches up Freerider. The challenging Monster Offwidth section – a 60-meter-long (almost 197 feet) crack around halfway through the climb – had put her off, and flashing the route, she says, wasn’t a long-standing target for her.

    “It was more that we just could try to go flash and see how far we can get,” Zangerl explains. “But the expectations were really low, so it was not a big goal from the beginning … There are some really slabby pitches where you don’t have hand holds, so you’re mostly standing on the bad feet, and you always can slip off.

    “The chance was really low – I didn’t have the feeling that we have a big chance on the flash.”

    It was only once she had conquered the Boulder Problem – perhaps the hardest, most treacherous part of the climb with only razor-thin holds on which to grip – that the flash seemed possible.

    “Then it was kind of: you don’t want to f**k it up on the last part,” says Zangerl.

  3. 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.

  4. Chile’s President Boric leads journey to South Pole in historic trip

    Chile’s President Gabriel Boric travelled to Antarctica’s South Pole on Friday, a place where no other Latin American president has set foot, according to the Chilean government.

    Boric led the historic two-day trip, named Operation Pole Star III, to extend the environmental monitoring of pollutants on Antarctica, Chile’s government said in a statement.

    He travelled with scientists, armed forces commanders and government ministers from the Chilean capital of Santiago to Punta Arenas, a city in southern Chile, public broadcaster Television Nacional de Chile (TVN) reported. From there, they made several stops before finally reaching the US-run Amundsen-Scott South Pole Station, according to TVN.

    Chile is one of seven countries that has a territorial claim in Antarctica, alongside Argentina, Australia, France, New Zealand, Norway and the United Kingdom.

    It is also a signatory of the Antarctic Treaty, which dictates that the continent may only be used for peaceful and scientific purposes.

    While Chile has historically carried out scientific activity in Antarctica’s northern sector, the country’s government is now hoping to expand research into the west of the continent, its statement said.
    Boric called his trip to the South Pole an “honor” and a source of pride, TVN reported.

    “This is a milestone for us. It is the first time a Chilean and Latin American President has visited the South Pole,” he said, according to TVN.
