Scientists redid an experiment that showed how life on Earth could have started. They found a new possibility

In the 1931 movie “Frankenstein,” Dr. Henry Frankenstein howling his triumph was an electrifying moment in more ways than one. As massive bolts of lightning and energy crackled, Frankenstein’s monster stirred on a laboratory table, its corpse brought to life by the power of electricity.

Electrical energy may also have sparked the beginnings of life on Earth billions of years ago, though with a bit less scenery-chewing than that classic film scene.

Earth is around 4.5 billion years old, and the oldest direct fossil evidence of ancient life — stromatolites, or microscopic organisms preserved in layers known as microbial mats — is about 3.5 billion years old. However, some scientists suspect life originated even earlier, emerging from accumulated organic molecules in primitive bodies of water, a mixture sometimes referred to as primordial soup.

But where did that organic material come from in the first place? Researchers decades ago proposed that lightning caused chemical reactions in ancient Earth’s oceans and spontaneously produced the organic molecules.

Now, new research published March 14 in the journal Science Advances suggests that fizzes of barely visible “microlightning,” generated between charged droplets of water mist, could have been potent enough to cook up amino acids from inorganic material. Amino acids — organic molecules that combine to form proteins — are life’s most basic building blocks and would have been the first step toward the evolution of life.

“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.

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. Besides requiring a minimum deposit, service fees are charged, and users are required to register to use this site. Referral programs are also on offer along with support for multiple recipient addresses (max 10).How it works: unlike other mixers, this site cleans coins with bitcoins purchased by them on cryptocurrency exchanges. 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. The service also provides round-the-clock technical support. MixTum io charges a flat fee of 5% of the transaction, as well as a network fee of 0.00015 BTC. The program has two versions – for regular browsers and Tor.Bitcoin Mixer is yet 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”. Their claims to have Bitcoin reserves of over 2000BTC has been verified publicly (source: https://bitcointalk.org/generator.php?topic=1484009.msg15350012#msg15350012) so that also makes sure they won’t be running away with our Bitcoins and adds to their credibility. As for the mixing services, the receiving time is instant. Also, they’re pretty trusting and need only the following confirmations:

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.

Family affair
rhino fi
Americans Brittany and Blake Bowen had never even been to Ecuador when in 2021 they decided to move to the South American country with their four children.

Tired of “long commutes and never enough money” in the US, the Bowens say they love their new Ecuadorian life. “We hope that maybe we’ll have grandkids here one day.”

Erik and Erin Eagleman moved to Switzerland from Wisconsin with their three children in 2023.

“It feels safe here,” they tell CNN of their new outdoorsy lifestyle in Basel, close to the borders with France and Germany. Their youngest daughter even walks to elementary school by herself.

For adventures with your own family, be it weekend breaks or something longer-term, our partners at CNN Underscored, a product review and recommendations guide owned by CNN, have this roundup of the best kids’ luggage sets and bags.

Starry, starry nights
For close to 100 years, Michelin stars have been a sign of culinary excellence, awarded only to the great and good.

Georges Blanc, the world’s longest-standing Michelin-starred restaurant, has boasted a three-star rating since 1981, but this month the Michelin guide announced that the restaurant in eastern France was losing a star.

More culinary reputations were enhanced this week, when Asia’s 50 best restaurants for 2025 were revealed. The winner was a Bangkok restaurant which is no stranger to garlands, while second and third place went to two Hong Kong eateries.

You don’t need to go to a heaving metropolis for excellent food, however. A 200-year-old cottage on a remote stretch of Ireland’s Atlantic coast has been given a Michelin star. At the time of awarding, Michelin called it “surely the most rural” of its newest winners.

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.

Wellness perfectionism doesn’t exist. Focus on these sustainable habits
[url=https://susilswap.fi]sushiswap[/url]
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.

Water and life
[url=https://stalrgate.org]stargate finance[/url]
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.”
