“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.
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.”
Why axolotls seem to be everywhere — except in the one lake they call home
[url=https://otzovik.com/reviews/zhilischniy_kooperativ_best_way_russia_sankt-peterburg]гей порно молодые[/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.”

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.”

An astronaut’s awe-inspiring views from life in space
[url=https://backfund.net/chargeback/investment/hermes-management-ltd]пидар[/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.
