Why axolotls seem to be everywhere — except in the one lake they call home
смотреть порно жесток

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.”

A Russian-American woman who was imprisoned for treason by Russia has been freed, Secretary of State Marco Rubio said Thursday.

Former ballerina Ksenia Karelina was born in Russia but had built a new life as an aesthetician at a Los Angeles spa after immigrating to the United States over a decade ago. She “is on a plane back home to the United States,” having been “wrongfully detained by Russia for over a year,” Rubio said on in a post on X. He credited President Donald Trump with securing her release.

Karolina’s lawyer, Mikhail Mushailov, confirmed her release in a statement on Instagram. “Two hours ago she was in touch with her relatives and took off from Abu Dhabi to the U.S.,” he wrote, adding that he had known about her release since Tuesday.

Russia’s Federal Security Service (FSB) detained Karelina in January 2024 while she was visiting her parents and young sister in the city Yekaterinburg. It did not provide further details or evidence of her alleged crime.

At the time, Russian legal group Perviy Otdel said it had information that Karelina had donated just over $51.80 from her U.S. bank account on Feb. 24, 2022 — the day that Russia launched its full-scale invasion of Ukraine — to a charity that sends aid to Ukraine. A spa where she had previously worked confirmed this in a statement on Facebook.

Although Russia’s FSB did not confirm that figure, it said Karelina’s donation “was subsequently used to purchase tactical medical supplies, equipment, weapons, and ammunition for the Ukrainian armed forces.”

She was sentenced in August to 12 years in a penal colony for “high treason,” having “fully admitted her guilt” at a closed trial in the southwestern Russian city of Yekaterinberg, Sverdlovsky Region Court said in a news release at the time.

The sentence came against the backdrop of Russia’s 3-year-long war with Ukraine during which President Vladimir Putin’s government has cracked down on dissent. Any perceived criticism of the military is banned.

“Liberation Day” gave way to Capitulation Day last night.

President Donald Trump pulled back yesterday on a series of harsh tariffs targeting friends and foes alike in an audacious bid to remake the global economic order.

Trump’s early afternoon announcement followed a harrowing week in which Republican lawmakers and confidants privately warned him that the tariffs could wreck the economy. His own aides had quietly raised alarms about the financial markets before he suspended a tariff regime that he had unveiled with a flourish just one week earlier in a Rose Garden ceremony.

Reporting from Hong Kong

China's public language on its trade war with the U.S. has become increasingly bellicose and took a new turn today when Beijing's foreign ministry said the Trump administration's tariffs have made the U.S. a “barbarian of the 21st century.”

Trump’s tariffs will “never America great again” ministry of foreign affairs spokesperson Huang Jingrui, wrote in an open letter today in Hong Kong’s newspaper South China Morning Post.

“A tariff-wielding barbarian who attempts to force countries to call and beg for mercy can never expect that call from China,” Huang said, adding that the U.S. is “obsessed with the art of bullying and blackmailing the entire world.”

EU welcomes 90-day tariff pause

Peter Guo

The EU President Ursula von der Leyen said today that the region welcomes Trump’s announcement to pause tariffs for 90 days.

Von der Leyen said the EU remains “committed to constructive negotiations” with the U.S., according to a statement from her office.

Meanwhile, Europe continues to focus on diversifying their trade partnerships, engaging with countries that account for 87% of global trade, she said.

Trump’s tariffs have shown that the European internal market is the region’s “anchor of stability and resilience” in times of uncertainty, von der Leyen added.

Trade war with China 'to spark a wave of smuggling'

Peter Guo

Reporting from Hong Kong
mgmarket1 at
Irregular trade including smuggling will most likely rise amid the U.S.' and China's tit-for-tat tariffs, an economist warns.

The cost of tariffs has become “prohibitive to almost every company,” Tianchen Xu, senior economist at Economist Intelligence Unit.

“As a result, trade flows in both directions will tumble, and irregular trade will proliferate, including smuggling, transshipment and systemic under-reporting of trade value during customs clearance,” Xu said in a note.

Xu said trade negotiations and a partial de-escalation in the ongoing trade war may ensue in the coming months, but those tensions are likely to worsen in the short term between the world’s two largest economies.

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.)

A job for the Webb space telescope
kra31 at
“We got 53 candidates for anomalies that cannot be well explained, but can’t say that all of them are Dyson sphere candidates, because that’s not what we are specifically looking for,” said Gabriella Contardo, a postdoctoral research fellow at the International School for Advanced Studies in Trieste, Italy, who led the earlier study. She added that she plans to check the candidates against Suazo’s model to see how many tie into it.
https://kra30att.cc

“You need to eliminate all other hypotheses and explanations before saying that they could be a Dyson sphere,” she added. “To do so you need to also rule out that it’s not some kind of debris disk, or some kind of planetary collision, and that also pushes the science forward in other fields of astronomy — so it’s a win-win.”

Both Contardo and Suazo agree that more research is needed on the data, and that ultimately they could turn to NASA’s James Webb Space Telescope for more information, as it is powerful enough to observe the candidate stars directly. However, because of the lengthy, competitive procedures that regulate use of the telescope, securing access might take some time.
If Dyson spheres really exist, what could they be used for? “If you picture ourselves having as much energy as the sun is providing every second, we could do unheard of things,” Suazo said. “We could do interstellar travel, maybe we could even move the entire solar system to our preferred location, if we wanted.”

But don’t hold your breath, because the technology and the raw materials required to build the hypothetical structures are far beyond humanity’s grasp.

“They are so big that everything we have on Earth would not be enough to build them,” Suazo added. “Freeman Dyson said that we should dismantle Jupiter — the whole planet (for the raw materials).”

That supercolossal scale probably means that Dyson spheres, if they exist at all, are very rare.

‘Dyson spheres’ were theorized as a way to detect alien life. Scientists say they’ve found potential evidence
Кракен тор
What would be the ultimate solution to the energy problems of an advanced civilization? Renowned British American physicist Freeman Dyson theorized it would be a shell made up of mirrors or solar panels that completely surrounds a star — harnessing all the energy it produces.

“One should expect that, within a few thousand years of its entering the stage of industrial development, any intelligent species should be found occupying an artificial biosphere which completely surrounds its parent star,” wrote Dyson in a 1960 paper in which he first explained the concept
https://kra30c.cc

If it sounds like science fiction, that’s because it is: Dyson took the idea from Olaf Stapledon’s 1937 novel “Star Maker,” and he was always open about that. The late scientist was a professor emeritus at the Institute of Advanced Study in Princeton, New Jersey.
Still, coming from a thinker who some in the scientific community say might have been worthy of a Nobel Prize early in his career, the concept took hold and the hypothetical megastructures became known as Dyson spheres, even though the physicist later clarified that they would actually consist of “a loose collection or swarm of objects traveling on independent orbits around the star.”

In his paper, Dyson also noted that Dyson spheres would give off waste heat detectable as infrared radiation, and suggested that looking for that byproduct would be a viable method for searching for extraterrestrial life. However, he added that infrared radiation by itself would not necessarily mean extraterrestrial intelligence, and that one of the strongest reasons for searching for such sources was that new types of natural astronomical objects might be discovered.

“Scientists (at the time) were largely receptive, not to the likelihood that alien civilisations would be found to exist, but that a search for waste heat would be a good place to look,” said George Dyson, a technology writer and author and the second of Dyson’s six children, via email. “Science fiction, from ‘Footfall’ to ‘Star Trek,’ took the idea and ran with it, while social critics adopted the Dyson sphere as a vehicle for questioning the wisdom of unlimited technological growth.”
