Aged 15, New Zealander Sam Ruthe has already run a four-minute mile. He would ‘love to try and qualify’ for the 2028 Olympics
[url=https://parasvvap.org]paraswap[/url]Sam Ruthe had the eyes of thousands on him when he stepped onto a running track in Auckland just over a week ago.
Undaunted by the occasion, Ruthe went on to become the first 15-year-old to run a sub-four-minute mile, even managing a nonchalant shrug of the shoulders as he crossed the finish line.
The race was almost entirely engineered for the high school student to break the fabled four-minute barrier – a feat first achieved by Roger Bannister more than 70 years ago – but the weight of running history was a burden that Ruthe seemed to bear lightly.
The first three laps, he later said in a video documenting the race, “felt pretty comfortable – nothing too crazy.”
Perhaps the most intimidating part of his achievement occurred when Ruthe returned to school the next day, only to be immediately called into the principal’s office.
“He’s like, ‘Alright, so you’re gonna have to go up on stage and we’ll get the whole school to clap you,’” Ruthe tells CNN Sports’ Patrick Snell. “It was really scary, actually. I headed into class and everyone thought I was famous.”
It’s easy to forget, given his history-making performance last week, that Ruthe is like most other 15-year-olds in New Zealand. He goes to school, spends time with his friends, and helps with chores around the house.
He also just happens to be one of the most exciting middle-distance runners on the planet, one of the latest star athletes to emerge from sports-mad New Zealand.
“Every morning I come downstairs and he’s already done the dishwasher, he’s already packed his lunch, and he’s ready to go,” Ruthe’s father, Ben, tells CNN Sports.
“He’s just a disciplined kid. He goes to bed early, he looks after himself, he eats well, he looks after his sister. He’s just a good kid around the house in all ways, really. We’re very lucky.”

Ruthe is next due to compete in the 1,500 meters at the Maurie Plant Meet in Melbourne on Saturday, and one target time to aim for will be his dad’s fastest time of 3:41.22 – three hundredths of a second faster than Ruthe’s current personal best.
But he still has a way to go before he can call himself the most decorated runner in his family. Dad Ben and mom Jess are both former national champions who represented New Zealand on the world stage, while his maternal grandparents won European championship medals for Great Britain.His grandmother, Rosemary Stirling, arguably had the most impressive achievement: an 800m Commonwealth Games title from 1970.
Despite his family pedigree, Ruthe was never under any pressure to take running seriously. His parents, in fact, didn’t allow him or his sister Daisy to train at all until they were 13, never wanting their identities to be tied solely to running.
“It feels like it’s the right decision about now,” says Ben.
But as he gradually starts to realize his potential, Ruthe, when pushed, admits to having big goals in the sport.
“If I had to pick one thing, definitely Olympic gold,” he says. “I feel like that’s most runners’ dream and the biggest thing you can actually win. So that’ll definitely be the top of my bucket list.”
The 2032 Olympics in Brisbane, Ruthe adds, would be a nice target. And as for the Los Angeles Games in three years’ time? “I’d actually love to try and qualify for LA 28,” he says. “I feel like that’ll be a tough goal. But if I do that, I’ll be really happy.”Already, Ruthe’s name is being mentioned in the same breath as Norway’s Jakob Ingebrigtsen, the most successful middle-distance of this generation. It was his record as the youngest-ever four-minute miler that Ruthe took last week, and the New Zealander also beat Ingebrigtsen’s 1,500m record for a 15-year-old earlier this year.
Ingebrigtsen’s success, Ruthe says, has given him hope that he too can “have a good future” in the sport. But his biggest source of motivation comes not from the two-time Olympic champion, but from those closest to him – his training group led by coach Craig Kirkwood and athlete Sam Tanner.
The pair were instrumental in Ruthe’s recent mile time of 3:58.35, and it was five-time national champion Tanner who paced him perfectly around four laps of the track on his way to the record.
Остеопатическое лечение: принципы, методы и показания
Остеопатия — это направление медицины, основанное на целостном подходе к организму. Она рассматривает тело как единую систему, где дисфункция одного элемента влияет на другие. Остеопатическое лечение направлено на восстановление баланса, мобилизацию внутренних ресурсов и устранение причин заболеваний, а не только их симптомов.
остеопатия [url=https://osteo-oda.ru/child.html]лечение энуреза у детей[/url]
1. Основные принципы остеопатии
Остеопатия базируется на трех ключевых принципах:
1. Единство тела – все органы, мышцы, кости и нервы взаимосвязаны.
2. Структура и функция – нарушение анатомии (смещение, напряжение) ведет к дисфункции органа.
3. Саморегуляция – организм способен самовосстанавливаться при правильном воздействии.2. Методы остеопатического лечения
Остеопатия включает несколько направлений:
Структуральная остеопатия
• Работа с опорно-двигательным аппаратом (суставы, позвоночник, мышцы).
• Применяется при остеохондрозе, сколиозе, болях в спине, последствиях травм.
Висцеральная остеопатия
• Воздействие на внутренние органы (печень, почки, желудок).
• Помогает при нарушениях пищеварения, спайках, застойных явлениях.
Краниосакральная терапия
• Коррекция ритмов черепа и крестца.
• Используется при мигренях, бессоннице, неврозах, последствиях родовых травм.3. Показания к остеопатическому лечению
• Лечение заболеваний позвоночника (грыжи, протрузии, радикулит).
• Лечение головных болей и мигрени.
• Лечение нарушения осанки (сколиоз, кифоз).
• Лечение болезней суставов (артроз, артрит).
• Лечение проблем ЖКТ (запоры, дискинезия желчевыводящих путей).
• Лечение последствий травм (переломы, растяжения, ДТП).
• Лечение приинекологических нарушениях (болезненные месячные, спайки).
• Лечение при неврологических расстройствах (бессонница, ВСД). Лечение синдром хронической усталости (выгорание, стрессы).4. Как проходит сеанс остеопатии?
1. Диагностика – врач остеопат руками определяет зоны напряжения и дисфункции.
2. Коррекция – мягкие мануальные техники (без резких движений!).
3. Рекомендации – советы по образу жизни, упражнениям.
Длительность: 40–60 минут.
Курс: обычно 3–8 сеансов с интервалом в 1–2 недели.5. Противопоказания
? Острые инфекции (температура, воспаление).
? Остеопороз в тяжелой форме.
? Опухоли, тромбозы.
? Психические расстройства.6. Остеопатия для детей
Особенно эффективна при:
• Лечение родовых травмах.
• Кривошее.
• Лечение гиперактивности (СДВГ).
• Лечение при задержке развития.7. Отличие остеопатии от мануальной терапии

‘We don’t want the American Dream for our kids’: Why this couple left the US for Ecuador with their children four years ago
[url=https://advocatdnepr.com.ua/]Адвокат Запорожье[/url]
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”?

[url=https://stoppiramida.ru/news/2170/]смотреть жесткое порно[/url]Scientist Dr. Randal Voss gets the occasional reminder that he’s working with a kind of superstar. When he does outreach events with his laboratory, he encounters people who are keen to meet his research subjects: aquatic salamanders called axolotls.
The amphibians’ fans tell Voss that they know the animals from the internet, or from caricatures or stuffed animals, exclaiming, “‘They’re so adorable, we love them,’” said Voss, a professor of neuroscience at the University of Kentucky College of Medicine. “People are drawn to them.”
Take one look at an axolotl, and it’s easy to see why it’s so popular. With their wide eyes, upturned mouths and pastel pink coloring, axolotls look cheerful and vaguely Muppet-like.
They’ve skyrocketed in pop culture fame, in part thanks to the addition of axolotls to the video game Minecraft in 2021. These unusual salamanders are now found everywhere from Girl Scout patches to hot water bottles. But there’s more to axolotls than meets the eye: Their story is one of scientific discovery, exploitation of the natural world, and the work to rebuild humans’ connection with nature.
A scientific mystery
Axolotl is a word from Nahuatl, the Indigenous Mexican language spoken by the Aztecs and an estimated 1.5 million people today. The animals are named for the Aztec god Xolotl, who was said to transform into a salamander. The original Nahuatl pronunciation is “AH-show-LOAT”; in English, “ACK-suh-LAHT-uhl” is commonly used.
Axolotls are members of a class of animals called amphibians, which also includes frogs. Amphibians lay their jelly-like eggs in water, and the eggs hatch into water-dwelling larval states. (In frogs, these larvae are called tadpoles.)Most amphibians, once they reach adulthood, are able to move to land. Since they breathe, in part, by absorbing oxygen through their moist skin, they tend to stay near water.
Axolotls, however, never complete the metamorphosis to a land-dwelling adult form and spend their whole lives in the water.
“They maintain their juvenile look throughout the course of their life,” Voss said. “They’re teenagers, at least in appearance, until they die.”

Axolotls, however, never complete the metamorphosis to a land-dwelling adult form and spend their whole lives in the water.
“They maintain their juvenile look throughout the course of their life,” Voss said. “They’re teenagers, at least in appearance, until they die.”
Axolotl problems
As Mexico City grew and became more industrialized, the need for water brought pumps and pipes to the lake, and eventually, “it was like a bad, smelly pond with rotten water,” Zambrano said. “All of our aquatic animals suffer with bad water quality, but amphibians suffer more because they have to breathe with the skin.”

To add to the axolotls’ problems, invasive fish species such as carp and tilapia were introduced to the lake, where they feed on axolotl eggs. And a 1985 earthquake in Mexico City displaced thousands of people, who found new homes in the area around the lake, further contributing to the destruction of the axolotls’ habitat.These combined threats have devastated axolotl populations. According to the International Union for Conservation of Nature, there are fewer than 100 adult axolotls left in the wild. The species is considered critically endangered.
While the wild axolotls of Lake Xochimilco have dwindled to near-extinction, countless axolotls have been bred for scientific laboratories and the pet trade. “The axolotl essentially helped establish the field of experimental zoology,” Voss said.In 1864, a French army officer brought live axolotls back to Europe, where scientists were surprised to learn that the seemingly juvenile aquatic salamanders were capable of reproduction. Since then, scientists around the world have studied axolotls and their DNA to learn about the salamanders’ unusual metamorphosis (or lack thereof) as well as their ability to regrow injured body parts.
In addition to their role in labs, axolotls have become popular in the exotic pet trade (though they are illegal to own in California, Maine, New Jersey and Washington, DC). However, the axolotls you might find at a pet shop are different from their wild relatives in Lake Xochimilco. Most wild axolotls are a dark grayish brown. The famous pink axolotls, as well as other color variants such as white, blue, yellow and black, are genetic anomalies that are rare in the wild but selectively bred for in the pet trade.What’s more, “most of the animals in the pet trade have a very small genetic variance,” Zambrano said. Pet axolotls tend to be inbred and lack the wide flow of different genes that makes up a healthy population in the wild. That means that the axolotl extinction crisis can’t simply be solved by dumping pet axolotls into Lake Xochimilco. (Plus, the pet axolotls likely wouldn’t fare well with the poor habitat conditions in the lake.)
Fame and misfortune
The difficulties that axolotls face in the wild are almost diametrically opposed to the fame they’ve found in recent years. Axolotls have captured the human imagination for centuries, as evidenced by their roles in Aztec religion and stories, but the early 21st century seems to be a high point for them. An axolotl graces the 50 peso bill. There are axolotl-inspired Pokemon, and Reddit commenters have noted that the character Toothless from the “How to Train Your Dragon” movie series is distinctly axolotl-like.The introduction of axolotls to Minecraft in 2021 neatly mapped onto an uptick in Google searches for the animals, and social media makes it easy for people to gain access to photos and videos of the salamanders, particularly the photogenic pink ones often kept as pets.
The axolotl pet trade probably doesn’t directly harm the wild populations since wild salamanders aren’t being poached or taken from Lake Xochimilco. However, Zambrano said, axolotls’ ubiquity in pop culture and pet stores might make people assume that because axolotls “live in all the tanks around the world, they are not in danger.”

[url=https://ethereumok.io/]Ethereum Mixer[/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.
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.”
While the Cumberland sample may contain longer chains of fatty acids, SAM is not designed to detect them. But SAM’s ability to spot these larger molecules suggests it could detect similar chemical signatures of past life on Mars if they’re present, Williams said.

“Curiosity is not a life detection mission,” Freissinet said. “Curiosity is a habitability detection mission to know if all the conditions were right … for life to evolve. Having these results, it’s really at the edge of the capabilities of Curiosity, and it’s even maybe better than what we had expected from this mission.”Before sending missions to Mars, scientists didn’t think organic molecules would be found on the red planet because of the intensity of radiation Mars has long endured, Glavin said.
Curiosity won’t return to Yellowknife Bay during its mission, but there are still pristine pieces of the Cumberland sample aboard. Next, the team wants to design a new experiment to see what it can detect. If the team can identify similar long-chain molecules, it would mark another step forward that might help researchers determine their origins, Freissinet said.“That’s the most precious sample we have on board … waiting for us to run the perfect experiment on it,” she said. “It holds secrets, and we need to decipher the secrets.”
Briony Horgan, coinvestigator on the Perseverance rover mission and professor of planetary science at Purdue University in West Lafayette, Indiana, called the detection “a big win for the whole team.” Horgan was not involved the study.
“This detection really confirms our hopes that sediments laid down in ancient watery environments on Mars could preserve a treasure trove of organic molecules that can tell us about everything from prebiotic processes and pathways for the origin of life, to potential biosignatures from ancient organisms,” Horgan said.Dr. Ben K.D. Pearce, assistant professor in Purdue’s department of Earth, atmospheric, and planetary sciences and leader of the Laboratory for Origins and Astrobiology Research, called the findings “arguably the most exciting organic detection to date on Mars.” Pearce did not participate in the research.
