Water and life
Eth Mixer
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.
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.”

The authors of the study, published May 6 in the journal Monthly Notices of the Royal Astronomical Society, specifically set out to search for Dyson spheres, in the form of infrared heat near stars that couldn’t be explained in any other way.

Using historical data from telescopes that pick up infrared signatures, the research team looked at stars located within less than 1,000 light-years from Earth: “We started with a sample of 5 million stars, and we applied filters to try to get rid of as much data contamination as possible,” said lead study author Matias Suazo, a doctoral student in the department of physics and astronomy of Uppsala University in Sweden.

“So far, we have seven sources that we know are glowing in the infrared but we don’t know why, so they stand out.”

There is no conclusive evidence that the seven stars have Dyson spheres around them, Suazo cautioned.

“It’s difficult for us to find an explanation for these sources, because we don’t have enough data to prove what is the real cause of the infrared glow,” he said. “They could be Dyson spheres, because they behave like our models predict, but they could be something else as well.”

Among the natural causes that could explain the infrared glow are an unlucky alignment in the observation, with a galaxy in the background overlapping with the star, planetary collisions creating debris, or the fact that the stars may be young and therefore still surrounded by disks of hot debris from which planets would later form.
The data used by the researchers comes from two active space telescopes — the Wide-field Infrared Survey Explorer, or WISE, from NASA and Gaia from the European Space Agency — as well as an astronomical survey of the sky in infrared light called The Two Micron All Sky Survey. Also known as 2MASS, the collaboration between the University of Massachusetts and the US space agency’s Jet Propulsion Laboratory took place between 1997 and 2001.

Americans nearing retirement and recent retirees said they were anxious and frustrated following a second day of market turmoil that hit their 401(k)s after President Donald Trump’s escalation of tariffs.

As the impending tariffs shook the global economy Friday, people who were planning on their retirement accounts to carry them through their golden years said the economic chaos was hitting too close to home.

Some said they are pausing big-ticket purchases and reconsidering home renovations, while others said they fear their quality of life will be adversely affected by all the turmoil.

“I’m just kind of stunned, and with so much money in the market, we just sort of have to hope we have enough time to recover,” said Paula, 68, a former occupational health professional in New Jersey who retired three years ago.

Paula, who spoke on the condition of anonymity because she feared retaliation for speaking out against Trump administration policies, said she was worried about what lies ahead.

“What we’ve been doing is trying to enjoy the time that we have, but you want to be able to make it last,” Paula said Friday. “I have no confidence here.”

Trump fulfilled his campaign promise this week to unleash sweeping tariffs, including on the United States’ largest trading partners, in a move that has sparked fears of a global trade war. The decision sent the stock market spinning. On Friday afternoon, the broad-based S&P 500 closed down 6%, the tech-heavy Nasdaq dropped 5.8%, and the Dow Jones Industrial Average fell more than 2,200 points, or about 5.5%.

‘We don’t want the American Dream for our kids’: Why this couple left the US for Ecuador with their children four years ago
адвокат Дніпро
They’d never even visited Ecuador before, but Brittany and Blake Bowen, from the United States, decided to move to the South American country in 2021 to give their four children a completely different upbringing.

The Bowens, who were previously based in the state of Washington, have been living in Loja, a small city based in the southern section of the Andes Mountains, ever since, and say that they are in it for the long haul.

“We love this little country,” Brittany tells CNN Travel. “We hope that maybe we’ll have grandkids here one day.”
Before the move, the couple, who’ve been married for nearly 17 years, say that they were becoming increasingly concerned about the pressures placed on children by “modern American society” and wanted to try something new.

“We did not like what we’d seen develop over the course of the last couple decades…” adds Brittany, explaining that they felt that young people in the United States were becoming “more isolated.”

“We weren’t confident that our kids would enjoy the same sort of potential trajectory that previous generations had shared.

“And the more we considered things like that, the more we wondered, ‘Is that even what we want? Do we even want them to be on a fast track to the American Dream?”

The couple were also frustrated with living what they describe as the “standard American life.”

“Long commutes and never enough money,” says Blake. “All those usual problems… I was working in a career that was very time consuming, and took me away from home a lot. So we didn’t want that anymore.”

So why did they choose Ecuador as their “new home”?

President Donald Trump on Thursday blamed the Federal Aviation Administration’s “diversity push” in part for the plane collision that killed 67 people in Washington, DC. But DEI backers, including most top US companies, believe a push for diversity has been good for their businesses.

Trump did not cite any evidence for how efforts to hire more minorities, people with disabilities and other groups less represented in American workforces led to the crash, saying “it just could have been” and that he had “common sense.” But Trump criticized the FAA’s effort to recruit people with disabilities during Joe Biden’s administration, even though the FAA’s Aviation Safety Workforce Plan for the 2020-2029 period, issued under Trump’s first administration, promoted and supported “the hiring of people with disabilities and targeted disabilities.”

It’s not the first time opponents of diversity, equity and inclusion initiatives, or DEI, have said they can kill people. “DEI means people DIE,” Elon Musk said after the California wildfires, criticizing the Los Angeles Fire Department and city and state officials for their efforts to advance diversity in their workforces.
