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.”
WASHINGTON — “Liberation Day” just gave way to Capitulation Day.

President Donald Trump pulled back Wednesday 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.

The stock market rose immediately after the about-face, ending days of losses that have forced older Americans who’ve been sinking their savings into 401(k)s to rethink their retirement plans.
Ahead of Trump’s announcement, some of his advisers had been in a near panic about the bond markets, according to a senior administration official. Interest rates on 10-year Treasury bonds had been rising, contrary to what normally happens when stock prices fall and investors seek safety in treasuries. The unusual dynamic meant that at the same time the tariffs could push up prices, people would be paying more to buy homes or pay off credit card debt because of higher interest rates. Businesses looking to expand would pay more for new loans.

Two of Trump’s most senior advisers, Treasury Secretary Scott Bessent and Commerce Secretary Howard Lutnick, presented a united front Wednesday, urging him to suspend the tariffs in light of the bond market, the administration official said.
In a social media post, Trump announced a 90-day pause that he said he’ll use to negotiate deals with dozens of countries that have expressed openness to revising trade terms that he contends exploit American businesses and workers. One exception is China. Trump upped the tariff on the country’s biggest geopolitical rival to 125%, part of a tit-for-tat escalation in an evolving trade war.
Trump reversed course one week after he appeared in the Rose Garden and unveiled his plan to bring jobs back to the United States. Displaying a chart showing the new, elevated tariffs that countries would face, Trump proclaimed, “My fellow Americans, this is Liberation Day.”

‘A whole different mindset’ Accurate clockwork is one matter. But how future astronauts living and working on the lunar surface will experience time is a different question entirely. kraken ссылка On Earth our sense of one day is governed by the fact that the planet completes one rotation every 24 hours giving most locations a consistent cycle of daylight and darkened nights. On the moon however the equator receives roughly 14 days of sunlight followed by 14 days of darkness. “It’s just a very very different concept” on the moon Betts said. “And NASA is talking about landing astronauts in the very interesting south polar region of the moon where you have permanently lit and permanently shadowed areas. So that’s a whole other set of confusion.” https://kra30c.cc kraken зайти “It’ll be challenging” for those astronauts Betts added. “It’s so different than Earth and it’s just a whole different mindset.” That will be true no matter what time is displayed on the astronauts’ watches. Still precision timekeeping matters — not just for the sake of scientifically understanding the passage of time on the moon but also for setting up all the infrastructure necessary to carry out missions. The beauty of creating a time scale from scratch Gramling said is that scientists can take everything they have learned about timekeeping on Earth and apply it to a new system on the moon. And if scientists can get it right on the moon she added they can get it right later down the road if NASA fulfills its goal of sending astronauts deeper into the solar system. “We are very much looking at executing this on the moon learning what we can learn” Gramling said “so that we are prepared to do the same thing on Mars or other future bodies.”
Lunar clockwork What scientists know for certain is that they need to get precision timekeeping instruments to the moon. kra30cc Exactly who pays for lunar clocks which type of clocks will go and where they’ll be positioned are all questions that remain up in the air Gramling said. “We have to work all of this out” she said. “I don’t think we know yet. I think it will be an amalgamation of several different things.” https://kra30c.cc kra31cc Atomic clocks Gramling noted are great for long-term stability and crystal oscillators have an advantage for short-term stability. “You never trust one clock” Gramling added. “And you never trust two clocks.” Clocks of various types could be placed inside satellites that orbit the moon or perhaps at the precise locations on the lunar surface that astronauts will one day visit. As for price an atomic clock worthy of space travel could cost around a few million dollars according Gramling with crystal oscillators coming in substantially cheaper. But Patla said you get what you pay for. “The very cheap oscillators may be off by milliseconds or even 10s of milliseconds” he added. “And that is important because for navigation purposes — we need to have the clocks synchronized to 10s of nanoseconds.” A network of clocks on the moon could work in concert to inform the new lunar time scale just as atomic clocks do for UTC on Earth. There will not Gramling added be different time zones on the moon. “There have been conversations about creating different zones with the answer: ‘No’” she said. “But that could change in the future.”
Space time: The continual question If time moves differently on the peaks of mountains than the shores of the ocean you can imagine that things get even more bizarre the farther away from Earth you travel. kraken зайти To add more complication: Time also passes slower the faster a person or spacecraft is moving according to Einstein’s theory of special relativity. Astronauts on the International Space Station for example are lucky said Dr. Bijunath Patla a theoretical physicist with the US National Institute of Standards and Technology in a phone interview. Though the space station orbits about 200 miles 322 kilometers above Earth’s surface it also travels at high speeds — looping the planet 16 times per day — so the effects of relativity somewhat cancel each other out Patla said. For that reason astronauts on the orbiting laboratory can easily use Earth time to stay on schedule. https://kra30c.cc kraken даркнет For other missions — it’s not so simple. Fortunately scientists already have decades of experience contending with the complexities. Spacecraft for example are equipped with their own clocks called oscillators Gramling said. “They maintain their own time” Gramling said. “And most of our operations for spacecraft — even spacecraft that are all the way out at Pluto or the Kuiper Belt like New Horizons — rely on ground stations that are back on Earth. So everything they’re doing has to correlate with UTC.” But those spacecraft also rely on their own kept time Gramling said. Vehicles exploring deep into the solar system for example have to know — based on their own time scale — when they are approaching a planet in case the spacecraft needs to use that planetary body for navigational purposes she added. For 50 years scientists have also been able to observe atomic clocks that are tucked aboard GPS satellites which orbit Earth about 12550 miles 20200 kilometers away — or about one-nineteenth the distance between our planet and the moon. Studying those clocks has given scientists a great starting point to begin extrapolating further as they set out to establish a new time scale for the moon Patla said. “We can easily compare GPS clocks to clocks on the ground” Patla said adding that scientists have found a way to gently slow GPS clocks down making them tick more in-line with Earth-bound clocks. “Obviously it’s not as easy as it sounds but it’s easier than making a mess.”

I think it will be an amalgamation of several different things.” https://kra30c.cc kra31 cc Atomic clocks Gramling noted are great for long-term stability and crystal oscillators have an advantage for short-term stability. “You never trust one clock” Gramling added. “And you never trust two clocks.” Clocks of various types could be placed inside satellites that orbit the moon or perhaps at the precise locations on the lunar surface that astronauts will one day visit. As for price an atomic clock worthy of space travel could cost around a few million dollars according Gramling with crystal oscillators coming in substantially cheaper. But Patla said you get what you pay for. “The very cheap oscillators may be off by milliseconds or even 10s of milliseconds” he added. “And that is important because for navigation purposes — we need to have the clocks synchronized to 10s of nanoseconds.” A network of clocks on the moon could work in concert to inform the new lunar time scale just as atomic clocks do for UTC on Earth. There will not Gramling added be different time zones on the moon. “There have been conversations about creating different zones with the answer: ‘No’” she said. “But that could change in the future.”
