An astronaut’s awe-inspiring views from life in space
[url=https://www.vokalcherezbokal.ru/151124/novosti-vasilenko-roman-poslednie-novosti/]гей онлайн[/url]
Longtime NASA astronaut Don Pettit, who has ventured to space four times, returned to Earth on Saturday night from the International Space Station. Pettit, who turned 70 on Sunday, landed at 9:20 p.m. ET in a Soyuz spacecraft with Roscosmos cosmonauts Alexey Ovchinin and Ivan Vagner near Zhezkazgan, Kazakhstan, after a seven-month stay aboard the orbiting laboratory.The scientist invented the first object patented in space — called the Capillary Beverage, Space Cup or Zero-G cup, which makes it easier to drink beverages in the absence of gravity, and he is also a celebrated astrophotographer known for capturing unique views of the cosmos.
“One of the things I like to do with my astrophotography is to have a composition and a perspective that’s different than an Earth-centric one, typically showing an Earth horizon with the atmosphere on edge, the limb, and then some kind of astronomy, astrophotography, in relationship to that,” Pettit said from the space station during an April 3 interview with astrophysicist Neil deGrasse Tyson.
“Earth is amazingly beautiful when your feet are firmly planted on the ground, and it’s beautiful from space,” Pettit said. “And it’s hard to say what is more beautiful. I think it’s because space is a unique opportunity we seek to focus on the beauty of being in orbit. If we had people living their whole life in orbit, when they come down to Earth, they would probably think that was the most beautiful perspective they’d ever seen.”Pettit takes his photos from the cupola on the space station, a favorite of crew members due to its seven windows that overlook Earth.
Here are some of his most unforgettable views of what it’s like to live in space that he captured over the past seven months.
Mindful wellness challenges
If you’re the type of person who thrives on challenges and pushing your limits, this doesn’t mean you need to shy away from wellness challenges altogether. But before diving in, take a step back and ask yourself if you’re pursuing the challenge for the right reasons, McGregor said.

Some people want to try these challenges because they believe something is missing from their life, and they’re looking to attain “worth” or receive validation, McGregor noted.A good way to assess your motivation is by considering whether the challenge will benefit your health or if it’s about showcasing your accomplishments on social media or some other reason.
Before trying any new trend, make sure you have the foundation to handle it and be aware of any potential risks, McGregor said.
For casual runners, this might mean signing up for a 5K but building your endurance gradually while incorporating other strength training exercises into your routine. For more intense challenges, such as a marathon, McGregor encourages people to consult with professionals or a coach who can monitor your progress and condition along the way.
Focusing on sustainable habits
Both McGregor and Curran emphasize the importance of fostering sustainable health habits before embarking on more extreme challenges.Rather than chasing the idea of being “healthy,” McGregor suggests focusing on actual healthful behaviors and starting small.
If you’re a highly sedentary person and want to add more movement to your day, try doing lunges while brushing your teeth or taking short walks throughout your typical routine.
Scientists redid an experiment that showed how life on Earth could have started. They found a new possibility
[url=https://web-safepal.com]safepal[/url]
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.
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.”
Josh Giddey hits halfcourt buzzer-beater over LeBron James to cap wild finale as the Bulls stun the Lakers
[url=https://qulckswap.net]quickswap[/url]
Josh Giddey hit a game-winning, halfcourt buzzer-beater over LeBron James as the Chicago Bulls stunned the Los Angeles Lakers in one of the wildest endings to an NBA game you are ever likely to see.Trailing 115-110 with 12.6 seconds remaining, Giddey’s inbound pass found Nikola Vucevic, who pushed the ball to a wide-open Patrick Williams for a corner three-pointer.
James then fluffed the Lakers inbound pass from the baseline, allowing Giddey to steal the ball and find Coby White for a second Bulls triple in quick succession to put Chicago up 116-115 with 6.1 seconds remaining.
Austin Reaves then made a driving layup to put the Lakers ahead 117-116 with 3.3 seconds left, but the game wasn’t done yet.With no timeouts remaining, Giddey inbounded the ball to Williams from the baseline, got the pass back, took one dribble and launched a shot from beyond halfcourt.
Supporters in the stands seemed frozen in anticipation as the ball sailed through the air, and the United Center then erupted as it fell through the net. After the dramatic win, Giddey found himself being swarmed by his teammates.
“Special moment to do it with these guys, this team,” Giddey said, per ESPN. “We’ve shown over the last month to six weeks that we can beat anybody. The way we play the game, I think it wears people down.
“We get up and down. We run. We put heat on them to get back. A lot of veteran teams don’t particularly want to get back and play in transition.”
Giddey later told the Bulls broadcast that he’d “never made a game-winner before.”
The ending capped an incredible couple of games for the Lakers, who had themselves won their last game against the Indiana Pacers on Wednesday with a buzzer-beating tip-in from James.

[url=https://kyderswap.com]kyberswap[/url]
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.

It’s pursuing “a supposed course of development that is actually backward and destructive,” she told CNN.
[url=https://ke1pdao.net]kelpdao[/url]
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.
