  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. 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. Medical staff on the front line of the battle against mpox in eastern Democratic Republic of Congo have told the BBC they are desperate for vaccines to arrive so they can stem the rate of new infections.

    At a treatment centre in South Kivu province that the BBC visited in the epicentre of the outbreak, they say more patients are arriving every day – especially babies – and there is a shortage of essential equipment.

    Mpox – formerly known as monkeypox – is a highly contagious disease and has killed at least 635 people in DR Congo this year.
    Even though 200,000 vaccines, donated by the European Commission, were flown into the capital, Kinshasa, last week, they are yet to be transported across this vast country – and it could be several weeks before they reach South Kivu.
    “We’ve learned from social media that the vaccine is already available,” Emmanuel Fikiri, a nurse working at the clinic that has been turned into a specialist centre to tackle the virus, told the BBC.
    He said this was the first time he had treated patients with mpox and every day he feared catching it and passing it on to his own children – aged seven, five and one.
    “You saw how I touched the patients because that’s my job as a nurse. So, we’re asking the government to help us by first giving us the vaccines.”
    The reason it will take time to transport the vaccines is that they need to be stored at a precise temperature – below freezing – to maintain their potency, plus they need to be sent to rural areas of South Kivu, like Kamituga, Kavumu and Lwiro, where the outbreak is rife.
    The lack of infrastructure and bad roads mean that helicopters could possibly be used to drop some of the vaccines, which will further drive up costs in a country that is already struggling financially.
    At the community clinic, Dr Pacifique Karanzo appeared fatigued and downbeat having been rushed off his feet all morning.
    Although he wore a face shield, I could see the sweat running down his face. He said he was saddened to see patients sharing beds.
    “You will even see that the patients are sleeping on the floor,” he told me, clearly exasperated.
    “The only support we have already had is a little medicine for the patients and water. As far as other challenges are concerned, there’s still no staff motivation.”
