New design revealed for Airbus hydrogen plane
renzo protocol

In travel news this week: Bhutan’s spectacular new airport, the world’s first 3D-printed train station has been built in Japan, plus new designs for Airbus’ zero-emission aircraft and France’s next-generation high-speed trains.

Grand designs
European aerospace giant Airbus has revealed a new design for its upcoming fully electric, hydrogen-powered ZEROe aircraft. powered by hydrogen fuel cells.

The single-aisle plane now has four engines, rather than six, each powered by their own fuel cell stack.

The reworked design comes after the news that the ZEROe will be in our skies later than Airbus hoped.

The plan was to launch a zero-emission aircraft by 2035, but now the next-generation single-aisle aircraft is slated to enter service in the second half of the 2030s.

Over in Asia, the Himalayan country of Bhutan is building a gloriously Zen-like new airport befitting a nation with its very own happiness index.

Gelephu International is designed to serve a brand new “mindfulness city,” planned for southern Bhutan, near its border with India.

In rail travel, Japan has just built the world’s first 3D-printed train station, which took just two and a half hours to construct, according to The Japan Times. That’s even shorter than the whizzy six hours it was projected to take.

France’s high-speed TGV rail service has revealed its next generation of trains, which will be capable of reaching speeds of up to 320 kilometers an hour (nearly 200 mph).

The stylish interiors have been causing a stir online, as has the double-decker dining car.

Finally, work is underway in London on turning a mile-long series of secret World War II tunnels under a tube station into a major new tourist attraction. CNN took a look inside.

Water and life
stargate finance
Lightning is a dramatic display of electrical power, but it is also sporadic and unpredictable. Even on a volatile Earth billions of years ago, lightning may have been too infrequent to produce amino acids in quantities sufficient for life — a fact that has cast doubt on such theories in the past, Zare said.

Water spray, however, would have been more common than lightning. A more likely scenario is that mist-generated microlightning constantly zapped amino acids into existence from pools and puddles, where the molecules could accumulate and form more complex molecules, eventually leading to the evolution of life.

“Microdischarges between obviously charged water microdroplets make all the organic molecules observed previously in the Miller-Urey experiment,” Zare said. “We propose that this is a new mechanism for the prebiotic synthesis of molecules that constitute the building blocks of life.”

However, even with the new findings about microlightning, questions remain about life’s origins, he added. While some scientists support the notion of electrically charged beginnings for life’s earliest building blocks, an alternative abiogenesis hypothesis proposes that Earth’s first amino acids were cooked up around hydrothermal vents on the seafloor, produced by a combination of seawater, hydrogen-rich fluids and extreme pressure.

Researchers identified salt minerals in the Bennu samples that were deposited as a result of brine evaporation from the asteroid’s parent body. In particular, they found a number of sodium salts, such as the needles of hydrated sodium carbonate highlighted in purple in this false-colored image – salts that could easily have been compromised if the samples had been exposed to water in Earth’s atmosphere.

Yet another hypothesis suggests that organic molecules didn’t originate on Earth at all. Rather, they formed in space and were carried here by comets or fragments of asteroids, a process known as panspermia.

“We still don’t know the answer to this question,” Zare said. “But I think we’re closer to understanding something more about what could have happened.”

Though the details of life’s origins on Earth may never be fully explained, “this study provides another avenue for the formation of molecules crucial to the origin of life,” Williams said. “Water is a ubiquitous aspect of our world, giving rise to the moniker ‘Blue Marble’ to describe the Earth from space. Perhaps the falling of water, the most crucial element that sustains us, also played a greater role in the origin of life on Earth than we previously recognized.”

“You have a government that is reckless about what is going to happen to Guyana,” said Melinda Janki, an international lawyer in Guyana who is handling several lawsuits against Exxon. It’s pursuing “a supposed course of development that is actually backward and destructive,” she told CNN.

And while plenty of Guyanese people welcome the new oil industry, some say Guyana’s startling economic statistics do not reflect a real-world prosperity for ordinary people, many of whom are struggling with the higher prices accompanying the oil boom. Inflation rose 6.6% in 2023, with prices of some foods shooting up much more rapidly.

“Since the oil extraction began in Guyana, we have noticed that our cost of living has gone sky high,” said Wintress White, of Red Thread, a non-profit that focuses on improving living conditions for Guyanese women. “The money is not trickling down to the masses,” she told CNN.

CNN contacted President Ali, the Ministry of Natural Resources and the Ministry of Finance for comment but received no response.
Guyana, a former Dutch then British colony which gained independence in 1966, is one of only a handful of countries that is a “carbon sink,” meaning it stores more planet-heating pollution than it produces. This is due to its vast rainforest; trees remove carbon dioxide from the atmosphere as they grow.

The country has protected its biodiversity where others have destroyed theirs, President Ali said in a BBC interview last year. In 2009, the country signed an agreement with Norway, which promised Guyana more than $250 million to preserve its 18.5 million hectares, or nearly 46 million acres, of forests.

Ali insists the country can balance climate leadership and fossil fuel exploitation. The new oil wealth will allow Guayana to develop, including building climate adaptations such as sea walls, he has said. He has also pointed to the continued failures of wealthy countries, already grown rich on their own fossil fuels, to help poorer countries with climate finance.

But there are concerns Guyana could fall victim to the “resource curse,” in which vast, new wealth ?can actually make life worse for those who live there.

A tiny rainforest country is growing into a petrostate. A US oil company could reap the biggest rewards
kyberswap
Guyana’s destiny changed in 2015. US fossil fuel giant Exxon discovered nearly 11 billion barrels of oil in the deep water off the coast of this tiny, rainforested country.

It was one of the most spectacular oil discoveries of recent decades. By 2019, Exxon and its partners, US oil company Hess and China-headquartered CNOOC, had started producing the fossil fuel.? They now pump around 650,000 barrels of oil a day, with plans to more than double this to 1.3 million by 2027.

Guyana now has the world’s highest expected oil production growth through 2035.

This country — sandwiched between Brazil, Venezuela and Suriname — has been hailed as a climate champion for the lush, well-preserved forests that carpet nearly 90% of its land. It is on the path to becoming a petrostate at the same time as the impacts of the fossil fuel-driven climate crisis escalate.

While the government says environmental protection and an oil industry can go hand-in-hand, and low-income countries must be allowed to exploit their own resources, critics say it’s a dangerous path in a warming world, and the benefits may ultimately skew toward Exxon — not Guyana.
Since Exxon’s transformative discovery, Guyana’s government has tightly embraced oil as a route to prosperity. In December 2019, then-President David Granger said in a speech, “petroleum resources will be utilized to provide the good life for all … Every Guyanese will benefit.”

It’s a narrative that has continued under current President Mohamed Irfaan Ali, who says new oil wealth will allow Guyana to develop better infrastructure, healthcare and climate adaptation.

Challenging our perceptions of ‘perfection’
traderjoexyz exchange
With health influencers raising the bar for success, the wellness space now often feels like a performative space where people strive to showcase peak physical and mental strength.

While seeing others’ achievements can be motivating, it can also be discouraging if your progress doesn’t match theirs.

Each person is chasing the perfect version of themselves — whether it’s a body or a lifestyle — which is dangerous because this is typically an impossible or dangerous version to achieve, Curran said. He added that this type of comparison creates a dangerous cycle in which people constantly feel dissatisfied with their own progress.

“It’s a fantasy in many ways, and once you start chasing after it, you constantly find yourself embroiled in a sense of doubt and deficit,” he said.

Curran also noted that wellness challenges can be particularly damaging for women who struggle with perfectionism, as they tend to be bombarded with impossible beauty standards and societal expectations.

Renee McGregor, a UK-based dietitian who specializes in eating disorders and athlete performance, encourages people to approach wellness trends with curiosity and skepticism. That’s because some influencers and celebrities could be promoting products because there’s a financial benefit for them.

“The thing to ask yourself about the person you’re taking advice from is what do they gain from it?” McGregor said. “If they are going to gain financially, then you know that they (could be willing) to sell you a lie.”
Whether you want to try a new challenge or product that promises amazing results, McGregor suggests doing your research and seeking diverse perspectives, including consulting with doctors when possible.

В сфере оптимизации сайта под поисковые системы (SEO) существует множество терминов и понятий, важных для продвижения. Ссылочный вес или ссылочная масса — один из важнейших факторов, влияющих на ранжирование веб-проекта в результатах поиска. В этой статье мы кратко рассказываем, что представляет собой ссылочная масса, какие ее типы выделяют, как она формируется и влияет на рейтинг сайта, а также даем несколько советов о ее наращивании.
ссылочная масса
Что такое ссылочная масса сайта
Ссылочный профиль (масса, вес) — это совокупность всех внешних гиперссылок, которые указывают на определенный сайт. Чем больше качественных внешних ссылок указывают на веб-ресурс, тем выше его авторитет с точки зрения поисковых систем. Поэтому внутренние ссылки, то есть оставленные в пределах самого сайта, ведущие на него же, не являются частью ссылочной массы.

Wellness perfectionism doesn’t exist. Focus on these sustainable habits
sushiswap
ou’re scrolling through your phone when you stumble upon the next viral trend: an influencer claiming that following their incredibly strict diet will help you achieve their jaw-dropping physique. Or you see a fresh-faced runner swearing you can run a marathon without any training — just like they did.

Whether or not you’re actively searching for wellness advice, it’s nearly impossible to avoid hearing about the latest health craze making bold guarantees of transformation.

As you wonder if these claims hold any truth, you might also question why people often feel motivated to dive into intense challenges — when seemingly simple habits, such as getting enough sleep or eating more vegetables, often feel much harder to tackle.

Many of us are drawn to these extreme challenges because we’re craving radical change, hoping it will help prove something to ourselves or to others, experts say.

“We always see these kinds of challenges as opportunities for growth, particularly if we’re in a phase of our life where we’ve let ourselves go,” said Dr. Thomas Curran, associate professor of psychology at the London School of Economics and Political Science and an expert on perfectionism. “Maybe we feel that we need to be healthier, or we just had a breakup or (major) life event.”
With social media amplifying these movements, it’s easy to see why people are increasingly drawn to the idea of achieving the “perfect” version of themselves. But before jumping into a new wellness challenge, it’s important to take a moment, reflect on your goals, and consider where you’re starting from.

Arctic auroras
[url=https://efhenna.org]ethena[/url]
For getting around during winter, the Inuit here nowadays prefer snowmobiles, although they still keep their sled dogs. During winter they’ll offer intrepid visitors, wrapped up warm against the deep-freeze temperatures, dog-sledding jaunts. These can last either an hour or be part of expeditions over several days, sometimes with the added experience of learning how to build an igloo. Sisimiut on the west coast and Tasilaq in the southeast are active winter centers for dog sledding.

Winter’s most stellar attraction, though, is northern lights watching. With little urban light pollution, Greenland is a dark canvas for spectacular displays, and aurora borealis-watching vacations are becoming more popular.

Staying outdoors, Greenland is developing a reputation among adventure enthusiasts: from long-distance skiing expeditions and heliskiing on the icecap to hiking the 100-mile-long Arctic Circle Trail from Kangerslussuaq, where firearms need to be carried for warning shots in case of polar bear encounters.

Life is definitely changing here. The climate crisis is eating away at its icecap and Greenland may well end up as a pawn in a game of geopolitical chess. But for now, the bright glare of international attention should shine a favorable light on one of the wildest travel destinations on Earth.

Travel writer Mark Stratton is an Arctic specialist who has traveled to Greenland six times and counting. He’s marveled at the aurora borealis, sailed to Disko Island, dog-sledded with the Inuit, and once got stuck in an icefloe.

Coinmize is another simple yet trustworthy Bitcoin Tumbler service. And one of the primary differences it has compared to the other platforms on this list is that it can accommodate really “large volume transactions”. There is no maximum transaction limit as such, considering how their reserve is really huge and you’ll need to be a millionaire before you can run them out of funds. If any limit is breached, you are notified before you make the payment. The minimum transaction 0.001BTC, any amount lower than this is is considered a donation, like in the case of PriveCoin, and isn’t sent back to the customer. The minimum fee is 0.5%, with an additional 0.0005BTC for every deposited transaction. You can set a custom fee for added anonymity and they also provide a letter or guarantee like all the mentionable Bitcoin Tumblers out there. Yomix : Excellent customer support Bitcoin Mixer : It offers flexible transaction fees and a low minimum transaction limit Coinmize : Zero-log policy Coin Mixer : Fast payouts Bitcoin Laundry : Uses stealth pools to anonymize transactions 1. Yomix - Excellent customer support Yomix supports Bitcoin cryptocurrency bearing no logs policy. It requires a minimum deposit of 0.001 BTC and the transaction fee is 0.5–3%. It supports multiple addresses of up to 10 and requires confirmation. No registration is required and it does offer a referral program. Letter of guarantee is provided.Based on the experience of many users on the Internet, Yomix is one of the leading Bitcoin tumblers that has ever appeared. This scrambler supports not only Bitcoins, but also other above-mentioned cryptocurrencies. Exactly this platform allows a user to exchange the coins, in other words to send one type of coins and get them back in another type of coins. This process even increases user’s anonymity. Time-delay feature helps to make a transaction untraceable, as it can be set up to 24 hours. There is a transaction fee of 0.0005 for each extra address.Bitcoin Mixer as the name suggests is another mixer, which lets us mix Yomix. It’s an onion-only service, and the lack of a clearnet version increases anonymity. Offers quite a bit of control to the users regarding percentage distribution and time-delays. Percentage distribution can be specified manually, while time-delays can only be “selected” from the provided options. Minimum possible delay is 1hour, maximum being 24 Hours, with multiple choices in between. Although “instant” payouts without any delay are possible as well. A total of 5 output addresses can be specified for each mix. The fee isn’t user-controlled, and is set at 1% of the mix. Each additional address costs an additional 0.000001 BTC. They do not store any logs whatsoever. The minimum deposit requirement is 0.0002 BTC, smaller deposits are considered donations and aren’t refunded.One absolutely unique crypto mixing service is Yomix because it is based on the totally different principle comparing to other services. A user does not just deposit coins to mix, but creates a wallet and funds it with chips from 0.01 BTC to 8.192 BTC which a user can break down according to their wishes. After chips are included in the wallet, a wallet holder can deposit coins to process. As the chips are sent to the mixing service beforehand, next transactions are nowhere to be found and there is no opportunity to connect them with the wallet owner. There is no usual fee for transactions on this mixing service: it uses “Pay what you like” feature. It means that the fee is randomized making transactions even more incognito and the service itself more affordable. Retention period is 7 days and every user has a chance to manually clear all logs prior to this period. Pros: Provides user-controlled time delays Doesn’t require registration 2. Bitcoin Mixer - It offers flexible transaction fees and a low minimum transaction limitSupporting multiple types of cryptocurrency, Bitcoin Mixer is one of the most flexible Bitcoin tumblers available today.

Bitcoin Mixer io examines purchased coins using a scoring system with innovative algorithms and the use of technologies such as blockchain volume analysis, cluster analysis, pollution analysis, etc. After that, you will receive your BTC back, divided into random parts, and even sent in different addresses, if necessary. The whole process takes about 6 hours. The mixer does not require registration and does not store any logs. After each mixing operation, a letter of guarantee is sent, and information about it is eliminated after 24 hours, ensuring complete anonymity.

If extraterrestrial life were to sign our Martian visitor book, what messages might it convey about its existence and intentions towards Earth, based on the patterns, symbols, or text it uses?


I know it’s a bit of a side note, but still wanted to mention it

A recently I stumbled on a site called [url=https://talabout.com] talabout.com[/url].

It’s full of interviews with people from all walks of life — unfiltered, not your typical media stuff.

Sometimes the vibe there reminds me of the stuff being shared here.

Anyone else seen it?
