Scientists redid an experiment that showed how life on Earth could have started. They found a new possibility
<a href=https://web-safepal.com>safepal</a>
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.

A tiny rainforest country is growing into a petrostate. A US oil company could reap the biggest rewards
<a href=https://svveli.com>swell network</a>
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.

Mist and microlightning

To recreate a scenario that may have produced Earth’s first organic molecules, researchers built upon experiments from 1953 when American chemists Stanley Miller and Harold Urey concocted a gas mixture mimicking the atmosphere of ancient Earth. Miller and Urey combined ammonia (NH3), methane (CH4), hydrogen (H2) and water, enclosed their “atmosphere” inside a glass sphere and jolted it with electricity, producing simple amino acids containing carbon and nitrogen. The Miller-Urey experiment, as it is now known, supported the scientific theory of abiogenesis: that life could emerge from nonliving molecules.
For the new study, scientists revisited the 1953 experiments but directed their attention toward electrical activity on a smaller scale, said senior study author Dr. Richard Zare, the Marguerite Blake Wilbur Professor of Natural Science and professor of chemistry at Stanford University in California. Zare and his colleagues looked at electricity exchange between charged water droplets measuring between 1 micron and 20 microns in diameter. (The width of a human hair is 100 microns.)

“The big droplets are positively charged. The little droplets are negatively charged,” Zare told CNN. “When droplets that have opposite charges are close together, electrons can jump from the negatively charged droplet to the positively charged droplet.”
The researchers mixed ammonia, carbon dioxide, methane and nitrogen in a glass bulb, then sprayed the gases with water mist, using a high-speed camera to capture faint flashes of microlightning in the vapor. When they examined the bulb’s contents, they found organic molecules with carbon-nitrogen bonds. These included the amino acid glycine and uracil, a nucleotide base in RNA.

“We discovered no new chemistry; we have actually reproduced all the chemistry that Miller and Urey did in 1953,” Zare said. Nor did the team discover new physics, he added — the experiments were based on known principles of electrostatics.

“What we have done, for the first time, is we have seen that little droplets, when they’re formed from water, actually emit light and get this spark,” Zare said. “That’s new. And that spark causes all types of chemical transformations.”

Critics say this power imbalance is clear in the 2016 contract Guyana signed with Exxon. Under the agreement, Exxon keeps 75% of everything it makes from its oil operations in Guyana, with the remaining 25% shared equally between the company and the government, which also takes a 2% royalty.
<a href=https://llidofl.fi>lido</a>
“It was a bad deal,” Ali said in the BBC interview, but he has rejected the idea of unilaterally changing the agreement, which was signed by the previous government. He says the next contract with Exxon will be on different terms.

An Exxon spokesperson said the contract is “globally competitive for countries at a similar stage of exploration” and said Guyana is averaging $1 billion a year in “oil profits.”

Exxon has also faced a number of lawsuits over its potential environmental impact, many filed by Melinda Janki, a Guyanese international lawyer, who drafted the country’s Environmental Protection Act back in the 1990s.

A big victory for Guyana’s people and environment came in 2023, when the court ruled Exxon should have unlimited liability for the costs of any oil spill. Exxon has since appealed the ruling and has posted a $2 billion guarantee while it awaits the appeal outcome.
Exxon said this commitment supplements “its robust balance sheets … and the insurance policies they already had in place.” Janki says this isn’t enough. Offshore oil spills can be extremely expensive to deal with, the 2010 Deepwater Horizon spill cost nearly $70 billion to clean up.

The push and pull between those who say oil offers Guyana a brighter future and those who fear the industry’s impact will continue.

Exxon said it’s had a positive impact on the country, including employing more than 6,200 people, investing more than $2 billion with local Guyanese businesses since 2015 and spending more than $43 million on community projects.

Look of the Week: Naomi Watts is twinning with her canine co-star
<a href=https://v2-orbiter.net>orbiter</a>
What’s white and black and red all over? Naomi Watts and her 145lb co-star, Bing, a Great Dane, taking a dog walk on the crimson carpet for the New York premiere of “The Friend.”

Directed by Scott Mcgehee and adapted from Sigrid Nunez’s 2018 novel of the same name, the film — set to release in US theaters on March 28 and in the UK on April 25 — follows a solitary writer and teacher named Iris whose life is upended after a close friend bequeaths his giant pet dog to her following his death.

In front of the cameras Monday evening, the “Mulholland Drive” actor and Bing looked like they were cut from the same cloth — both in temperament and in their matching black polka dots. Watts was dressed in a white gown with fur-tufted spots that bore a striking resemblance to Bing’s own coat, but the Cruella de Vil comparisons ended there. Instead, Watts and Bing were captured in the throes of lots of paw-shakes, puppy kisses and head scratches.
The dress that Watts wore, titled the “Domino” and designed by Jacquemus, debuted during the Spring-Summer 2025 Paris couture shows in January. The look was both elegant and offbeat, with a high-cowl neck and open-back, asymmetrical waistline that mimicked a French tuck. It was styled with a skirt that sprouted furry black polka dots, which close up were unnervingly reminiscent of body hair. But from afar they gave the impression of soft-edged dabs of watercolor bleeding downstream.

The look was styled by Jeanann Williams, who has also been working with “The White Lotus” star Leslie Bibb. Williams’ decision to coordinate Watts with Bing was a new take on method dressing — the thematic styling trend that has dominated celebrity red carpets since Greta Gerwig’s “Barbie” in 2023. Since then, the sartorial trope, which connects actors to their on-screen characters through clothes, has become somewhat tired — with some observers claiming that the 7-month-long “Wicked” press tour, in which Cynthia Erivo and Ariana Grande became prisoners to the colors green and pink, was peak saturation.

Tyler O’Neill hits record-extending sixth straight Opening Day home run
<a href=https://orbifer-fi.com>orbiter finance</a>
For six seasons in a row, Tyler O’Neill has homered on MLB Opening Day.

Making his debut for the Baltimore Orioles on Thursday, O’Neill started the season with his record-extending sixth straight home run on Opening Day during his team’s 12-2 win against the Toronto Blue Jays.

No other player has homered on more than four consecutive Opening Days, with the 29-year-old outfielder’s three-run shot sending the Orioles into a 5-0 lead at the top of the third at Rogers Centre.
Todd Hundley (1994-97), Gary Carter (1977-80) and Yogi Berra (1955-58) all hit four consecutive home runs on Opening Day, while the Major League Baseball record for the total number of Opening Day home runs is held jointly by Adam Dunn, Ken Griffey Jr. and Frank Robinson on eight.

“I’m just not trying to make too much of it,” O’Neill told reporters about his streak. “I’m just trying to go out, have a good first at-bat and see what the game gives me from there.

“Obviously, I understand what’s going on, but it’s not like I’m going out there trying to do anything crazy.”

O’Neill, who signed a three-year, $49.5 million contract to join Baltimore from the Boston Red Sox in the offseason, finished three-for-three with three RBIs and two walks against the Blue Jays.

“It’s a little different when the lights turn on and you’ve got to show up, so it was really cool to see all the guys show up today,” he said. “We got after it out there.”

While the first two games of the MLB regular season took place between the Chicago Cubs and Los Angeles Dodgers in Tokyo last week, Thursday marked the first official day of the season in the United States.
