Chile’s President Boric leads journey to South Pole in historic trip
kraken зеркало

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.

After shaking hands - it was the first time they had met - the pair debated policy before moving onto more personal attacks

Harris said people leave Trump rallies early "out of exhaustion and boredom" - he said people don't go to hers in the first place

Trump criticised Harris's record on immigration and the border, and also her shifting policy positions - Harris blamed him for "Trump abortion bans" and for the 6 January attacks on the US Capitol

Snap polls suggest Harris won the debate, but Trump says afterwards that she "lost very badly"

With the election taking place on 5 November, Harris is slightly ahead in national opinion polls - but polls are very tight in key battleground states

Shortly after the debate, Taylor Swift endorsed Harris on Instagram, calling her a ''gifted leader''

New Glenn’s first flight
Blue Origin formally announced the development of New Glenn — which aims to outpower SpaceX’s Falcon 9 rockets and haul spacecraft up to 45 metric tons (99,200 pounds) to orbit — in 2016.
kra27 at
The vehicle is long overdue, as the company previously targeted 2020 for its first launch.

Delays, however, are common in the aerospace industry. And the debut flight of a new vehicle is almost always significantly behind schedule.

Rocket companies also typically take a conservative approach to the first liftoff, launching dummy payloads such as hunks of metal or, as was the case with SpaceX’s Falcon Heavy debut in 2018, an old cherry red sports car.

Blue Origin has also branded itself as a company that aims to take a slow, diligent approach to rocket development that doesn’t “cut any corners,” according to Bezos, who founded Blue Origin and funds the company.

The company’s mascot is a tortoise, paying homage to “The Tortoise and the Hare” fable that made the “slow and steady wins the race” mantra a childhood staple.

“We believe slow is smooth and smooth is fast,” Bezos said in 2016. Those comments could be seen as an attempt to position Blue Origin as the anti-SpaceX, which is known to embrace speed and trial-and-error over slow, meticulous development processes.
But SpaceX has certainly won the race to orbit. The company’s first orbital rocket, the Falcon 1, made a successful launch in September 2008. The company has deployed hundreds of missions to orbit since then.

And while SpaceX routinely destroys rockets during test flights as it begins developing a new rocket, the company has a solid track record for operational missions. SpaceX’s Falcon 9 rocket, for example, has experienced two in-flight failures and one launchpad explosion but no catastrophic events during human missions.

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

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.

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

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.
https://kra26c.cc

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.”

Most plane crashes are ‘survivable’
kraken тор браузер
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.”
