Did these intriguing animals manage to effectively domesticate themselves?

Cat tales: history
Jerry D. Moore, Thames & Hudson

One weekend, I observed one of my family’s cats, a Byronic fellow named Solomon, playfully swat his sister, regurgitate on her bed linens right before my father, who loves birds, and finish off her gold crest. Yet we couldn’t hold it against Solomon. After all, I harbor no ill feelings toward him or his sister. This paradox defines the experience of cat enthusiasts.

The domesticated house cat (Felice Catus) stands as one of the world’s favorite pets. However, there remains uncertainty over whether they can genuinely be classified as domesticated and why anyone sought to do so in the first place. How did we come to cherish them in their various forms, particularly given that numerous species throughout history counted humans as prey?

In his book, archaeologist Jerry D. Moore delves into the origins of that inquiry, Cat tales: history. More noteworthy than its subtitle “History” is the cover’s text: “How we learned to coexist with them.” It’s ambiguous whether this reflects a human viewpoint or a disgruntled feline’s perspective. Regardless, this book is more about our evolving bonds with cats than a mere study of the creatures themselves.

The narrative of cat domestication narrates how, once humans formed settlements and began hoarding grain, rats descended to feast on their hard-won resources, leading them to the African wildcat (Felice Ribica). Thus, a mutually beneficial arrangement formed: humans stored the grain, and the cats enjoyed a free meal.

Yet, the reality is more nuanced, according to Moore. Domestication, typically involving breeding for specific traits, has only become prevalent with cats in the last century, as humans have aimed for particular appearances and unique characteristics. The humorous notion about cats comes to mind, but another frequent catalyst for domestication is herding.

Moore posits that understanding commensalism offers valuable insight into our bond with cats. Nevertheless, cats can exhibit fickle and aloof behavior, and mice often outmaneuver other species, such as terrier dogs. Cats seem to have confidently established themselves within human homes, suggesting an admirable sense of self-assurance. In essence, they have self-domesticated.

Moore effectively links the depictions of big cats in ancient cave art to their visibility in contemporary conservation campaigns. A 2018 study revealed that big cats consistently rank as among the most charismatic animals.

He also positions cats among history’s elite seafarers, traversing trade routes to Asia and the Mediterranean alongside African and Arab navigators. Their later journeys aboard European colonial vessels wreaked havoc in regions like Australia and New Zealand, where local fauna fell victim to feral cats.

While Moore’s writing occasionally flows gracefully, there are also meandering sections that detract from the book’s overall impact. A notable instance involves an early discussion on 20th-century human tool use. Initially puzzling, he later contends that portraying ancient humans as adept hunters minimizes the influence of ancient cats—the primary predators of our ancestors who shaped our physiology and cognition.

Moore indicates that the dynamics between cats and humans may have been more varied than those with other animals. “Cats have existed as agents of fear, subjects of veneration, deities in religious rites, and have been brutally exploited for amusement.”

For me, Cat tales may not present a wealth of groundbreaking information, but it serves as an excellent collection of archaeological insights paired with stunning photography. Even if our understanding of cats remains shrouded in some mystery after reading this book, perhaps that’s exactly how they prefer it.

Are There Any Cat Cryptocurrency Enthusiasts Out There?

Feedback offers the latest news in science and technology from New Scientist, highlighting the newest developments. Feel free to email Feedback@newscientist.com with items that would intrigue our readers.

On the Way Out

Cat-themed automatons were bound to happen, considering that the Internet is roughly 60% cats and 35% bots.

Thus, @pepitothecat, a black cat with a Twitter account known as Pepito, has caught attention. Residing in France with his owner, engineer Clément Storck, Pepito’s X account operates with a system that auto-posts whenever he enters or leaves via the cat flap.

The tweets, while seemingly mundane, say either “Pepito is not outside” or “Pepito is back home,” all timestamped to the nearest second and accompanied by monochrome photos and short videos of Pepito’s comings and goings.

Surprisingly, @PepitotheCat boasts over 860,000 followers, a notable number of whom are based in Brazil. In June 2017, Pepito went missing for 22 hours, causing a widespread stir.The impact on Brazil was significant. Interestingly, Storck had to write a post as Pepito returned through the “human door,” which wasn’t registered in the system.

Feedback would like to mention: 22 hours? That’s quite tame. One cat featured in Feedback often goes missing for a day or so, and a former cat disappeared for six weeks, only to be discovered just a few hundred meters from her usual spot.

Pepito is resilient; the account has been active for 14 years, and Pepito will turn 18 in September. Although he may seem like just another cat, recent news about Pepito’s owners selling has thrust the account into more controversial discussions, including Pepito-themed cryptocurrencies. After all, who doesn’t love cats?

I’m on Track

Feedback finds resonance with enthusiasts spending their allowances on Hornby model trains, even if we aren’t deeply involved in the hobby ourselves. Recently, we were excited (at the time of writing) when Alan Edgar noted a press release from Northern Rail, one of the UK’s privatized railway companies. In November 2024, the company introduced a new Commercial and Customer Director, one Alex Hornby, who has an impressive track record, as quoted by the managing director.

In our naming discussions, Ian Gammy came across a 2019 report assessing the greenhouse gas emissions attributed to the US military. It turns out, “The US military is among the largest historical climate polluters, consuming more liquid fuel and emitting more CO2 than most countries.” This underscores a stark contrast to the lack of such writings from American scholars, as highlighted by British researchers. Ian appreciated that the report’s authors included Patrick Big and Oliver Belcher.

You Just Lost

In March, Feedback explored Roko’s Basilisk, a rather bizarre thought experiment centered on artificial intelligence. Hypothetically, if an omnipotent AI were to exist, it might create simulations of individuals living today, raising a lot of confusion.

Our colleague Jacob Aron recently reviewed Matt Wixie’s novel Basilisk, which prompted reader Finn Byrne to delve into the concept of “cognitive hazard.” This notion implies that possessing certain knowledge may be perilous, especially regarding Roko’s Basilisk, which suggests that knowing about future AI may lead to eternal torment for those who refuse to aid its existence.

Unfortunately, events turned sour. When Finn reviewed the Wikipedia page on Cognitive Hazard, he “lost the game.” After he alerted us about it, we found ourselves losing as well. So now you’ve lost too.

As Finn describes, this game is simple: “1) you’re playing a game. 2) you lose every time you think about the game. 3) you must announce your loss.” Naturally, there’s a website dedicated to it: losethegame.net.

This game took up lots of time when we were students, often resurfacing during outings or in conversations, where a friend would suddenly declare they’ve lost. It had slipped our minds until now, but we’re back in its grip.

Finn continues to outline strategies. Winning appears impossible unless one achieves permanent amnesia or exits life prematurely, both of which seem extreme. However, you can certainly ensure others lose. “This website includes sections where enthusiastic players donate to worthy causes in light of ‘losing the game.’ If you prefer not to spend money, you might leave covert notes in strategic spots.

Lastly, there’s the award for publicizing the game widely. Finn notes these accolades often go to “individuals who mention the game in publications.”

Have you written to Feedback?

AI Unleashes a New Breed of Cat Videos: Addictive, Intrusive, and Nauseating Soap Opera Experiences

At the end of 2024, Billie Eilish took to the stage, seated herself, and began to play Miaou. Her fans erupted in harmony, attempting to overshadow their off-key presence. She knew, their dreams had materialized! Is this what Eilish’s Oscar-winning track was meant for? – “Lachrymose Barbie Cut Adulthood’s Ennui” has now become the quintessential soundtrack for an entirely new genre of cat video.

You may recognize it: these songs are often featured in AI-generated fantasies featuring human bodies with oddly detailed veins, reminiscent of cartoons, alongside hefty felines or equally muscular cats. Cats deceive their lovers, fall pregnant, and seek vengeance in bizarrely condensed melodramas. Much like traditional soap operas, these videos are incredibly addictive.

For example, this one. While diligently performing his tasks, Mr. Whiskers dons a red flannel shirt but accidentally ends up severing his legs while attempting to show off woodwork. He gets fired (evidently, the signs around the warehouse explicitly mention that all workers must “work with both hands”), his wife divorces him, and he struggles to piece together the fragments of his hard-knock life within 30 seconds. It all seems fine until his petite ex-wife plots to kill him, only to end up falling into a puddle and facing humiliation.

In another video, a baby tumbles into shark-infested waters, and a buff cat (dressed in Capri pants) comes to the rescue, adopting the child and taking it back to a mansion in Beverly Hills. Each narrative is neatly packaged, kitschily over-the-top, and unnaturally swift, offering millions of viewpoints.

The oversized felines in these video scenes suggest that Rev. Whisker and Mr. Whiskers aren’t just ordinary cats. They also embody certain human traits. Mogie, who sometimes resides in luxurious mansions, drives convertibles, and possesses a rugged, athletic physique, seems to be living the high life. Yet, many face regular struggles, illnesses, or dangers, despite their seemingly glamorous existences and comically pristine appearances, all set to eerie pop music underscoring their decline.

They find themselves tossed from ships, moaning amid house fires, dealing with substance issues, getting arrested, and being bullied. This prompts the question: Are these videos merely 30-second representations of warning signs? Are they about excess, betrayal, and redemption? Is Shakespeare somehow intertwined with Euripides? Are they modern-day parables?


Each video is marked by unfortunate domestic disasters: accidentally launching kittens into ceiling fans, or a cheating wife who neglects her husband’s pleas for attention. It’s an epic quest, entirely revolving around fur.

And it doesn’t take long for things to take a darker turn. In one unsettling video, Cat Rady finds himself submerged in Southern-Picked Cotton, just before being assaulted by a white cat clad in overalls. Each clip is disturbing, occasionally violent, and perpetually melodramatic, often garnished with bizarre AI-generated characters including erratic eagles and underwater sharks, all while the cats maintain a human-like physique and a bipedal swagger.

In another, “Luigi Meowgione” suffers as he watches his cat grandmother collapse in a grocery store. With her health insurance denied, he confronts the “Evil Corp Insurance” company, taking matters into his own hands and filling the building with Catnip gas. As a security guard falls victim to a grotesque case of Munch, Luigi Meowgione cleverly hacks the system, seemingly poised to confront the CEO… but we’re left hanging as part two hasn’t yet been revealed.

Ultimately, the Internet has always been enamored with felines possessing human characteristics. “Can I just have a cheeseburger?” This iconic phrase resonates because it encapsulates moments of feline discontent, showcasing the underlying personality. So, are these miaow-miaow videos the final evolution of anthropomorphized kittens? Or are they merely reproducing age-old motifs?

Cat Video Fest: How Adorable Kitten Clips Sparked a Million-Day Film Franchise | Cats

Title: Cat video.

Year: 131.

Genre: Authentic entertainment.

Wait a second, Is the cat video really 131 years old? Clearly, you haven’t seen Boxing Cats, a 20-second clip featuring two cats in boxing gloves fighting in tiny rings. Created in 1894 by Thomas Edison’s studio, it is preserved at the Library of Congress.

So you’re suggesting that humanity has not progressed Significantly in nearly a century and a half? No, I assert that there’s something vital about the charm of cat videos and their concurrent evolution.

But also … Indeed, humans have always had a knack for simple pleasures.

Now that we’ve established this, why are we discussing them today? Ah, because CatVideofest 2025 is on the horizon.

What is CatVideofest? Keep your finger on the pulse. Since 2016, Will Braden has meticulously curated online videos and public submissions into CatVideofest.

Seriously, is this a thing? Not only is it a thing, but it’s also a massive hit. The 2021 edition grossed $94,000 at the box office, while last year surpassed $1 million. If the trend continues, CatVideofest 2036 could become the most successful film ever.

So is there any merit? Sort of. Anyone who took children to CatVideofest 2024 will remember the relentless wave of cat videos that kicked off with an extraordinary 20-minute segment.

Which cat videos are featured in the movie? Ah, all the fan favorites. You can expect to see videos of cats sneaking across people, a cat knocking items off a table, and cats climbing things.

What about the toilet cat video? Ah, a classic of the genre. I didn’t realize I was discussing this with enthusiasts.

Of course. When I miss the 2011 classic, the day just barely goes by without “Cats walking on two legs 2.” Yes, what’s my favorite part…are we actually linking to cat videos now? I thought this was a serious discussion.

No, this is a discussion about how cinemas are learning to adjust to fresh audiences during widespread industry contraction. Very insightful. Almost as clever as a cat opening the door for its owner who forgot their key.

What does this reveal about us as a society? Well, the world is chaotic. Let’s unwind with some cat videos.

Say: “CatVideofest will be our salvation.”

Don’t say: “Not worse than the Smurfs.”

Webb Marks 3rd Anniversary with Stunning Cat Paw Star Photos

To celebrate the remarkable advancements in science during the third year, astronomers have utilized the NASA/ESA/CSA James Webb Space Telescope to capture images of the Cat’s Paw Nebula.



This web image depicts the Cat’s Paw Nebula, a significant star-forming region located 5,500 light years from the constellation Scorpio. Image credits: NASA/ESA/CSA/STSCI.

The Cat’s Paw Nebula resides in the southern constellation of Scorpio and is approximately 5,500 light years from Earth.

First identified in 1837 by British astronomer John Herschel, this dynamic star-forming region spans an estimated 80 to 90 light years.

Also known as NGC 6334 or the Bear Claw Nebula, it is one of the most vibrant stellar nurseries in the night sky, producing thousands of young, hot stars that emit light not visible from our perspective.

Recent images captured by Webb’s NIRCam instrument reveal structural details and functionalities previously unseen.

“Massive young stars are actively interacting with nearby gas and dust, and their bright stellar light produces a luminous, hazy glow, represented in blue,” Webb astronomers stated.

“This scenario illustrates a transient period where a destructive young star plays a significant role in the broader narrative of the region, characterized by relatively short lifespans and high luminosity.”

“Due to the dynamic activities of these massive stars, the local star formation process will eventually come to a halt.”

“We begin with a central area identified as the ‘opera house’ because of its hierarchical circulatory structure,” they noted.

“The principal sources of the blue glow in this area are likely positioned towards the bottom, obscured by dense brown dust, interspersed with light from bright, yellowish stars or nearby sources.”

“Beneath the orange-brown dust lies a bright yellow star displaying distinct diffraction spikes.”

“This giant star is sculpting its surrounding environment but has not managed to push gas and dust away sufficiently nor create a compact shell of surrounding material.”

“Take note of smaller regions, such as the tuning fork-shaped area adjacent to the opera house, which contains fewer stars.”

“These seemingly vacant zones are still in the process of forming stars, indicating the presence of dense filaments of dust that obscure the light of background stars.”

At the center of the image, small, fiery red masses can be seen scattered within the brown dust.

“These glowing red sources highlight areas where large-scale star formation is occurring, albeit in a less visible manner,” the researchers explained.

“Some of the blue-white stars, particularly in the lower left area, appear more sharply resolved than others.”

“This sharper appearance is attributed to the material between the star and the telescope being diffused by the star’s radiation.”

Near the bottom of this area is a compact dust filament.

“These small dust aggregates have managed to survive the intense radiation, indicating they are dense enough to give rise to protostars.”

The small yellow section on the right marks the location of a massive star still in its formative stages, managing to shine through the intervening material.

Numerous small yellow stars are scattered across the scene, displaying distinct diffraction spikes.

“The bright blue-white stars prominently feature in the foreground of this web image, with some possibly being part of the larger Cat’s Paw Nebula region.”

A particularly striking feature of this web image is the bright red-orange oval shape located in the top right corner.

The low concentration of background stars indicates it is a dense area where the star-forming process has only recently commenced.

Several visible stars are distributed throughout the region, contributing to the illumination of central materials.

Some of the developing stars have left behind traces of their existence, such as the shock wave visible in the lower left area.

Scientists Discover Genetic Variations Linked to Increased Cat Pairing

Cat (Ferris Katas) has become a beloved companion to people worldwide. Despite its widespread popularity, the genetic factors influencing its behavior have been largely unexplored. A new research team from the Kyoto University Wildlife Research Center has focused on the Androgen receptor gene (ar), located on the X chromosome, and its association with feline behaviors, such as purring.

Okamoto et al. found that male cats with short alleles displayed higher directional call/voicing scores, whereas females with short alleles exhibited increased aggression towards strangers compared to their counterparts with long alleles. Image credit: Natary Anderson.

“Cats are cherished companion animals that significantly contribute to society through their interactions with humans,” said lead author Okamoto and colleagues.

“However, most negrid species, such as the African Wildcat (Ferris Livica), have solitary ancestors, while domestic cats often form groups and display social behaviors.”

“They communicate with both humans and other cats utilizing a range of behaviors and signals, including olfactory cues, touch, visual cues, and vocalizations.”

“Purring, a distinctive vocalization of cats, plays a significant role in vocal communication.”

“Initially, purring may signify a mother’s health, but it continues to facilitate communication among cats beyond the weaning phase.”

“In a social context, purring promotes security and comfort, expresses familiarity, and invites play, though its precise function remains unclear.”

For this study, researchers evaluated the behavior of 280 cats, all of whom were neutered or mixed breeds living in their owners’ homes.

DNA samples were collected and analyzed to compare the ar gene with those from other negrid species.

“Upon reaching out to participants, we quickly received responses and warm messages from 265 cat owners across Japan within just a day,” Okamoto remarked.

“This highlighted the strong public interest in feline research.”

“The findings suggest a genetic basis for both purring and vocal communication.”

“Cats with the short-type androgen receptor gene received higher ratings from their owners than those with the long-type gene.”

“Additionally, male cats with the short form displayed increased vocalizations towards humans, indicating a genetic link to vocal communication.”

“Conversely, female cats with the shorter-type gene demonstrated heightened aggression towards unfamiliar individuals.”

“These findings could indicate a decreased significance of vocal communication in cats raised by humans from kittenhood, particularly those that are typically purebred.”

“Prior studies indicated that purebred cats are more likely to carry long-form genes than their mixed-breed counterparts.”

“This study included numerous mixed-breed cats that were rescued and were previously strays.”

Through comparisons of cat genes with 11 other genes, researchers discovered that both leopard and fishing cats were genetically similar to domestic cats and possessed shorter types, while domestic cats did not exhibit longer types found in other species.

These results imply that the emergence of long types may be linked to genetic changes related to domestication and selective breeding.

“These results may help predict behavioral trends based on genetic data, enhance observation and care based on needs, and ultimately improve animal welfare,” the authors stated.

The team plans to broaden their research focus to include other negrid species.

“Through our research, we aim to enrich our understanding of cats and foster better relationships between felines and humans,” Okamoto concluded.

This study was published online on May 28th in PLOS 1.

Science Confirms: A Ginger Cat is a Genetic Anomaly

The ginger cat results from a unique genetic variation that, as far as scientists can tell, isn’t found in other species.

A recent survey published in Current Biology reveals that this variation is linked to the faulty expression of a gene called Arhgap36, which has never been associated with the development of mammalian ginger fur.

Interestingly, this gene resides on the X chromosome, which helps explain why most orange cats are male.

Similar to other male animals, including humans, cats possess one X and one Y chromosome. The gene for orange fur is on the X chromosome; therefore, if a male inherits an X chromosome with the orange gene, he will display an entirely orange coat.

Conversely, female cats have two X chromosomes. To display complete orange fur, they must inherit the orange gene from both of their X chromosomes. If they inherit it on only one, the other X may carry a non-orange gene.

This results in a mix of colors in their fur—like the patchy orange, black, and white patterns observed in Calico and Tortoiseshell cats.

Female cats with one copy of the orange gene often have partially orange fur, like this calico cat. – Credit: Jacobi’s Nils via Getty

The relationship between orange fur and sex applies to cats but not to other orange mammals, such as tigers, orangutans, or red-haired humans.

According to Dr. Christopher Kaelin, Senior Scientist and Lead Author at Stanford Medicine Genetics and Research, the orange mutations in those animals occur due to one of two genes, neither of which are sex-linked.

As a result, orange cats appear to be “genetic exceptions.”

The study confirms that ginger cats exhibit genetic anomalies, but the evidence is still inconclusive regarding whether this unique trait contributes to their reputation for being a mischievous bunch.

To determine if the ARHGAP36 mutation has any impact beyond fur color, researchers have examined various organs, including the kidneys, heart, brain, and adrenal glands, in both orange and non-orange cats, finding no significant differences.

Kaelin remarked, “I don’t think we can exclude the possibility of gene expression changes in untested tissues that might influence behavior.”

He also mentioned that the prevalent notion of orange cats causing chaos could largely be attributed to their male predominance, noting that there is limited scientific research on the personalities of orange cats.

Ancient 29-Million-Year-Old Footprints of a ‘Saber-Toothed Cat’ Found in Oregon

Paleontologists have unearthed fossil footprints from both invertebrates and vertebrates, dating back between 500,000 and 25 million years, including a faux Saber Tooth cat (Nimravid).



Nimravid footprints from the John Day Formation in Oregon, USA. Image credit: NP.

John Day Fossil Bed National Monument (Joda) is renowned in central and eastern Oregon for its ancient mammalian fossils.

Paleontologists indicate that these specimens provide a nearly continuous 50 million-year record of mammalian evolution.

Within the Joda, four geological layers are identified: Clarno (50-39 million years), John Day (31-25 million years), Muscoll (16-12 million years), and rattlesnakes (8-6 million years).

The recently uncovered footprints belong to the Clarno and John Day layers.

“These footprints reveal intriguing behaviors and species previously undocumented in the extensive fossil records of the monument,” the researchers stated.

The series of footprints in the 29 million-year-old volcanic ash layer of the John Day Formation may have been created by Nimravid, a saber-toothed predator comparable in size to a bobcat, Hoplophoneus.

The absence of nail marks supports the notion of retractable nails, akin to modern-day felines.

Additionally, three round hoof prints of the same age likely belong to large herbivores, such as ancient tapirs and rhinoceroses.

Two small bird impressions, as well as a beak mark and an invertebrate trail, were found in the Clarno Formation.

These findings suggest ancient shorebirds were foraging for food in shallow waters.

Connor Bennett, a paleontologist at Utah Institute of Technology, remarked:

“It’s captivating; such a long duration for a species to maintain foraging patterns as seen in its ancestors.”

Within the same layer, scientists discovered an unusual fossil track featuring scattered toe impressions.

This indicates that lizards breaking through the lakebed represent one of the few known reptile trajectories from this period in North America.

“These tracks provide a unique window into ancient ecosystems,” stated Dr. Nicholas Famoso, Joda’s paleontology program manager.

“They add behavioral context to the body fossils amassed over the years, enhancing our understanding of prehistoric Oregon’s climate and environmental conditions.”

“Fossil tracks not only confirm the presence of these animals but also reveal their lifestyles,” Bennett added.

The team’s survey results will be published in the journal Palaeontologia Electronica.

Schrödinger’s Cat Warmed Up: A Potential Game-Changer in Quantum Physics

Scientists have achieved a breakthrough in quantum physics, creating a “Schrodinger Cat” state at warmer temperatures than previously thought possible.

This state relies on the concept of superposition, where particles can exist in multiple states simultaneously, a key principle of quantum mechanics.

The famous thought experiment by physicist Erwin Schrodinger involving a cat in a box with a radioactive material highlights the paradoxical nature of this concept.

Physicists have managed to create real Schrodinger cat particles, where quantum objects can exist in two states simultaneously without needing to be cooled to ground state temperature.

A recent study published in the journal Advances in Science has reported the creation of quantum states at ground state temperature.

In Erwin Schrödinger’s thought experiment, cats are alive and dead at the same time. Similar to how quantum objects occupy multiple states at once – Innsbruck University/Halaldricksch

Researchers at Innsbruck University have successfully produced the Schrodinger Cat state at a temperature of 1.8 Kelvin, a relatively warm temperature for quantum experiments.

This discovery challenges the traditional belief that quantum effects are disrupted by higher temperatures and opens up new possibilities for quantum technology.

Quantum computers, which could revolutionize technology by operating in multiple states, currently require expensive cooling methods. However, this study suggests that quantum phenomena can still be observed and utilized in warmer environments.

“Our work demonstrates that quantum interactions can persist even at higher temperatures, making temperature ultimately irrelevant for certain quantum effects,” said Professor Gerhard Kirchmair, one of the researchers involved in the study.

Scientists create conditions resembling a “superpositioned” Schrodinger’s cat

The principle of quantum superposition allows the system to be prepared with two arbitrary state superpositions. A paradigmous example is the superposition of two coherent states. Superposition of such states is usually referred to as the Schrödinger cat state, but in Irwin Schrodinger’s original thought experiment, a cat-temperature-equal system system is prepared with superposition of two mixed states dominated by classical variation. Physicists at the University of Innsbruck have now managed to create the state of Hot Schrodinger cats with a superconducting microwave resonator.

Yang et al. We generated highly mixed quantum states with different quantum properties. Image credit: Innsbruck University.

SchrödingerCat states are an attractive phenomenon in quantum physics, where quantum objects exist simultaneously in two different states.

In Erwin Schrödinger’s thought experiment, it is a cat living and dead at the same time.

In real experiments, such simultaneity is seen in the positions of atoms and molecules, as well as the vibrations of electromagnetic resonators.

Previously, these analogues to Schrodinger’s thought experiments were first created by cooling quantum objects to their ground state.

In a new study, Dr. Gerhard Kirchumere and his colleagues at Innsbruck University demonstrated that it is indeed possible to create quantum superpositions from thermally excited states.

“Schrodinger also envisioned a living, namely “hot” cat in his thought experiments,” says Dr. Kirchumere, author of the study.

“We wanted to know if these quantum effects could also be produced if they didn’t start from the ‘cold’ ground state. ”

To generate the Schrödinger CAT state, researchers used a transmon Qubit with a microwave resonator.

They have succeeded in creating quantum layers at temperatures up to 1.8 k. This is 60 times the ambient temperature of the cavity.

“Our results show that it is possible to generate highly mixed quantum states with distinct quantum properties,” says Dr. Ian Yang, the first author of the study.

Scientists used two special protocols to create the state of Hot Schrodinger cats.

These protocols have been used previously to produce CAT states starting from the ground state of the system.

“It turns out that the tuned protocol also works at high temperatures and produces clear quantum interference,” said Professor Oriol Romero Isart, co-author of the study.

“This opens up new opportunities for the creation and use of quantum superpositions, for example, in nanomechanical oscillators.

“When I first mentioned our results, many of our colleagues were surprised because we usually think of temperature as a disruption to quantum effects,” says Thomas Agnius, co-author of the study.

“Our measurements confirm that quantum interference can last even at high temperatures.”

The findings could benefit quantum technology development.

“Our work reveals that quantum phenomena can be observed and used in warm, less ideal environments,” Dr. Kirchem said.

“If the system can create the interactions it needs, temperature is ultimately irrelevant.”

a paper The findings were published in the journal Advances in science.

Scimitar-tooth cat cub found in permafrost in Yakutia estimated to be 36,000 years old

of Frozen specimen from 36,000 years ago Originally from Yakutia Homotherium latidensA species of scimitar-toothed cat that lived in Eurasia during the Pliocene and Pleistocene epochs.The modern lion cub is characterized by elongated front legs, an unusually shaped muzzle with a large mouth and small ears, and a very large body. differs greatly. Neck area and dark coat.

Homotherium latidens It was 1.5 to 2 meters long, up to 1.1 meters high, and weighed up to 200 kilograms, about the same size as an average modern lion or tiger.

However, its physical appearance is It was different Differences from other big cats: This extinct species had long saber-like canine teeth, a sloping back, and a short tail.

homotherium was widespread during the Pliocene to Pleistocene in Eurasia, Africa, and the Americas,” said lead author Dr. Alexei Lopatin and his colleagues.

“For a long time, as the latest presence, homotherium Records in Eurasia were recorded in the Middle Pleistocene. ”

“The key event was the discovery of a late Pleistocene mandible. Homotherium latidens It comes from the North Sea and dates back 28,000 years. ”

“The largest number of Late Pleistocene discoveries homotherium It is concentrated in North America (more than 30 regions), where it is traditionally classified as a species. homotherium serum

In the new study, the authors examined frozen mummified corpses. Homotherium latidens A baby discovered in the Pleistocene permafrost at a place called Badlyikskoe, along the Badlyikkha River in northeastern Yakutia, Siberia.

“A large number of bones of representative mammoth animals have been collected from the loess loam of the Yedma horizon in this region,” they said.

Researchers say the Bajarica specimen is about 36,000 years old.

“The specimen includes the head and the anterior part of the body, which was preserved up to the caudal end of the thorax,” the researchers said.

“Some people have an incomplete pelvis with joints that connect with the femur and shin bones.”

“The baby was found trapped in ice along with its front part.”

According to the team's analysis, most of the postcranial features are Homotherium latidens It can be tracked already at 3 weeks of age.

“The length of the preserved part is homotherium The length from the tip of the baby's nose to the thoracic gap (at the level of the 12th vertebra) is 248 mm,” the scientists said.

“The body is Covered with short, thick, soft dark brown fur The length of the hair is about 20-30mm. The fur on the back and neck is longer than on the legs. ”

“Two rows of wool are clearly visible on the upper lip, most of which are broken off at a height of 3 to 5 mm from the base.”

“The hair around the corners of the mouth has grown considerably.”

“The overall morphology of the skull is typical of juvenile felines,” the researchers added.

“The skull is also characterized by a relatively long facial area, a rounded braincase, an expanded zygomatic arch, a wide area of ​​the premaxilla, and large maxillary deciduous incisors.”

“The bones of the nose are homotherium Compared to lion cubs, the cubs are significantly shorter and wider. ”

“The neck is longer than a lion's and more than twice as thick,” they said.

“The difference in thickness is explained by the large amount of muscle visually observed at the site where the skin was separated from the mummified flesh.”

“The length of the forelimb is homotherium Lion cubs are 18-23% larger than baby lions. ”

“At the same time, the body length of the latter is homotherium Or about 10% more. ”

“The increased size of the mouth cleft indicates adaptation to a wider mouth cleft.”

front paws homotherium turnip It has a round shape. Its width is about the same as its body length, in contrast to lion cubs, whose front legs are long and relatively narrow. ”

“All claws are sharp and strongly curved. In cross section, the claws are laterally compressed, giving them the same shape as a lion cub.”

“The wide feet, square-shaped pads, and lack of carpal pads are adaptations to walking in snow and cold temperatures.”

“The pinna is small and low, and there is no carpal bone in Bajarica.” homotherium This contrasts with the taller pinnae and normally developed pads of lion cubs. All these characteristics can be interpreted as adaptations to life in cold climates. ”

discovery of Homotherium latidens Cub fundamentally expands our understanding of the distribution of this genus and confirms its presence in the Late Pleistocene of Asia.

“For the first time in the history of paleontological research, the appearance of an extinct mammal with no analogues in modern fauna has been directly studied,” the authors concluded.

Incorrect and Correct Ways to Pet a Cat

What’s the best way to pet a cat? Answer: Probably not the way you do it. You might think petting is a tried-and-true way to bond with your cat, but there’s no guarantee that your cat will enjoy the physical contact.

As Dr. Lauren Finca, a cat behavior expert from Nottingham Trent University explains: “While some cats do enjoy being petted, most cats would dislike the type of petting we typically prefer. The reason cats tolerate petting so well is likely due to the benefits of the relationship with their owner – think of the food, treats and affection you give your cat.”

“When it comes to petting, it’s best to remember that cats are not naturally social or tactile animals.”

In short, if you suspect your cat is only resisting your petting because he wants another bite of dinner, you’re probably totally right — especially if you’re constantly touching his butt.

“Certainly, from a scientific perspective, we know very little about this. It’s often assumed that cats like to be stroked at the base of their tails, but research shows that this is actually Elicit the most negative behavioral responses from cats” says Finca.

Why your cat insists on sitting on your laptop (not as charming as you think)

Are you the owner of a lovely and precious cat? Then your cat might be blocking the display of this page and ruining everything again, especially if you are reading this page on a laptop.

But what is the reason behind this behavior? Why are cats so obsessed with our computers?

Unfortunately, no large-scale (and probably highly impractical) scientific experiments have yet been conducted to delve into this question, but experts in cat behavior do have an important theory that might explain keyboard cats.



Why does my cat sit on my laptop?

Unfortunately, it’s probably not a case of imitation behavior — your cat just sees you typing and doesn’t want to join in.

Indeed, recent research suggests that felines can mimic human behavior. Cats can map their bodies onto humans to repeat actions(For example, touching the box with the head or a specific limb).

but, Dr. David Sands – Animal Psychology Expert with over 25 years of clinical experience – Cats cannot easily imitate the behavior of typing, so your cat probably won’t be interested if you tempt him with a decoy old laptop.

Read more about cats:

It’s also unlikely that cats are attracted solely to the heat emitted by laptops: “Yes, laptops do generate heat, and cats do like warm places, but you need to ask why a cat wouldn’t sit next to a radiator, for example,” Sands says.

What really makes your laptop attractive to cats is its smell — or, more specifically, the smell you keep on it.

“You can’t smell it, but your cat can smell you all over the keyboard,” Sands says.

“Cats are olfactory machines, from the tip of their tail to the tip of their nose. Their world revolves around smells. Their eyesight is developed for nocturnal hunting, and their sense of smell is Really Other times it matters.”

But while it’s possible that your cat is sitting on your computer because it enjoys the smell, Sands says another explanation is far more likely.

“Your cat is most likely trying to steal your scent by leaving his own scent on you. It’s a matter of ownership. By doing this, your cat is essentially saying, ‘You’re mine!'”

“People often think that when a cat rubs itself against you or the objects you touch it’s an affectionate sign, but in reality cats are very possessive creatures. The more they rub against you and leave your scent behind, the better!”

In case you’re wondering whether cats are desperately trying to become the dominant force in the home, Sands adds: “Dogs have been bred to be companions to humans, but cats have also become quite feral. Cats have been bred primarily for pest control, so they are selfish creatures rather than sociable animals.”

“Remember, cats are evil geniuses. They James Bond There’s a reason to watch movies.”

Is it unhealthy for my cat to sit on my laptop?

From making you close important documents without saving to sending your boss another “s,ll,;;;;;l;mk” message, a cat snuggling on your laptop can take a huge toll on you. If your cat is getting in the way of your work, Sands recommends cleaning your laptop regularly.

But your cat is unlikely to be harmed by lounging on your computer: “Physically, it’s not harmful, and cognitively, it’s only something to be concerned about if this behavior occurs with other cats,” he says.

“If your cat meows a lot and follows you around the house, it could be a sign of anxiety or attention-seeking.”

But what if your cat isn’t showing these signs? There’s no reason why your cat can’t lie on your keyboard – it owns it, and everything else in your home.

The correct and incorrect way to pet a cat

Wondering how to best pet a cat? The answer might surprise you. Although petting is often considered a bonding activity, not all cats enjoy it.

As Dr. Lauren Finca, a cat behavior expert from Nottingham Trent University, explains: “While some cats may like being petted, most cats may not be thrilled with our typical petting methods. Cats tolerate petting due to the positive relationship with their owners, including treats, food, and affection.”

“Cats are not naturally social or tactile animals, so when it comes to petting, it’s important to keep in mind their preferences,” advises Finca.

It’s essential to pay attention to your cat’s body language to understand their comfort levels with petting. Avoid areas like the lower back and belly, as touching these spots can make cats feel threatened due to their exposed vital organs.

According to Finca, early socialization and handling play a significant role in a cat’s tolerance for petting. Each cat’s preferences may vary, so it’s crucial to observe their reactions and adjust accordingly.

Watch out for signs of negative arousal in cats, such as turning away, freezing, or abrupt grooming behaviors. Cats may subtly communicate their discomfort through tail movements, ear positions, or body language.

What’s the best way to pet a cat?

When petting a cat, focus on areas like the cheeks, chin, and base of the ears, where cats enjoy being touched. Look for signs of positive excitement like purring, rubbing, and tail wagging to ensure your cat is comfortable.

Remember Dr. Finca’s guidelines for petting, known as CAT:

  • C: Give your cat choice and control during interactions, allowing them to approach you for petting.
  • A: Pay attention to your cat’s behavior and body language to recognize signs of discomfort or the need for a break.
  • T: Think about where you’re touching the cat, focusing on areas they enjoy and avoiding sensitive spots like the tail and belly.

By following these guidelines, you can ensure a positive petting experience for both you and your feline friend.

New discovery shows scimitar-toothed cat Homotherium found in new locations

Paleontologists from the University of Texas at Austin and other institutions have discovered fragments of the jaw of a feline with scimitar teeth. Homotherium McFaddin Beach, Texas. Homotherium from the continental shelf of the Gulf of Mexico. The topography may have formed a broad subtropical gulf coastal corridor that facilitated the dispersal of Neotropical species along the coast between Texas and Florida. The associated fauna at McFaddin Beach includes Neotropical mammals common to South Texas and Florida, Homotherium It was a type of animal that lived in the Gulf Coast Corridor during the Late Pleistocene.

Homotherium It is an extinct genus of scimitar-toothed cat that lived in the Americas, Eurasia, and Africa during the Pliocene and Pleistocene epochs, from about 4 million to 12,000 years ago.

These animals are large, sturdy cats about the size of a jaguar, with elongated faces, long, slender front legs, and sloping backs that end in short, cropped tails.

Their serrated canines were covered with large gum tissue, similar to that of modern domestic dogs.

Their fossils have been found in several areas of Texas, but the newly discovered remains show for the first time that the big cats roamed the now-submerged continental shelf between Texas and Florida.

“This region was a neotropical corridor,” said John Moretti, a doctoral student at the University of Texas at Austin, and his colleagues.

“Animals that couldn't move any further north, such as capybaras and giant armadillos, used these moist grasslands to migrate from Mexico to Texas and Florida.”

In this fossil specimen Homotherium Moretti's research otherstwo teeth are visible at the bottom: an incisor and the tip of a partially evolved canine. Scale bar – 1 cm. Image courtesy of Sam Houston State University.

The fossils studied by the team were discovered more than 60 years ago. McFaddin BeachIt was written by Professor Russell Long of Lamar University, south of Beaumont.

“The fossil appears to consist of a few exposed teeth in a rugged, rounded rock that appears slightly damaged after being submerged and tumbling on the bottom of the Gulf of Mexico for thousands of years before washing up on the shore,” the researchers said.

“But when we X-rayed the fossil, we found more than met the eye: hidden canines that had not yet erupted from the jawbone.”

“That was the information we needed to identify the fossils as belonging to a specific organism. HomotheriumIt is a genus of large cats that roamed large areas of the Earth for millions of years.”

“This cat wasn't fully developed when it died, so its characteristic sabre-shaped canines hadn't fallen out of place. The teeth were still nestled inside the jaw, protecting them from the environment.”

“If the sabre teeth had been fully developed and in their adult form, rather than during the awkward period of their mid-teens, they would have broken right away,” Moretti said.

“It wouldn't have been there and it couldn't have been used as evidence.”

“The discovery Homotherium “Studying the animals that lived along this corridor gives scientists a glimpse into the local ecosystem during the Late Pleistocene,” he added.

“These large carnivores, like cats, helped shape the wider animal community, suppressing prey populations and impacting local biodiversity.”

Can you trust a robot to care for your cat?

Created by scientists and explosion theory artists from the University of Nottingham cat royale is a multispecies world centered around a custom-built enclosure where three cats and a robotic arm coexist for six hours a day during a 12-day installation period.

Professor Steve Benford from the University of Nottingham and colleagues said: “Robots are finding a place in everyday life, from cleaning houses to mowing the lawn, shopping around hospitals and delivering parcels.”

“In doing so, they will inevitably have interactions and encounters with animals.”

“They could be companion animals, pets that share a home, guide dogs that help people navigate public places, but they could also be wild animals.”

“Often these encounters are unplanned and incidental to the robot’s primary mission, such as navigating a world inhabited by cats riding Roombas, guide dogs confused by delivery robots, and lawn mowing robots. Such as a hedgehog.”

“But it could also be intentional. We could also design robots to serve animals.”

“Little is known about how to design robots for animals, even though such encounters are inevitable, whether planned or not. Can you do that?

“We present Cat Royale, a creative quest to design a domestic robot to enrich cats’ lives through play.”

schneiders other. It suggests we need more than carefully designed robots to care for cats. In addition to human interaction, the environment in which the robot operates is also important. Image credit: Schneiders other., doi: 10.1145/3613904.3642115.

Cat Royale was unveiled at the World Science Festival in Brisbane, Australia in 2023, has been touring ever since, and just won a Webby Award for its creative experience.

The installation centers around a robotic arm that provides activities to make cats happier, including dragging a “mouse” toy along the floor and raising a feathered “bird” into the air. , which included feeding the cat treats.

The team then trained the AI to learn which games cats liked best so they could personalize their experience.

“At first glance, this project is about designing a robot that can play with cats and enrich the lives of families,” Professor Benford says.

“But beneath the surface, we are exploring the question of what it takes to entrust robots to care for our loved ones, and in some cases, ourselves.”

By working with Blast Theory to develop and study Cat Royale, researchers gained important insights into robot design and interaction with cats.

They had to design a robot that would pick up toys and deploy them in a way that excited the cats, all while learning which games each cat liked.

They also designed an entire world for the cat and robot to live in, providing a safe space for the cat to observe and sneak around the robot, and decorating it so that the robot had the best chance of spotting the approaching cat. did.

This means that robot design involves not only engineering and AI, but also interior design.

If you want to bring a robot into your home to take care of your loved ones, you will likely need to redesign your home.

Dr Ike Schneiders, a researcher at the University of Nottingham, said: ‘As we learned through Cat Royale, to create a multi-species system where cats, robots and humans are all taken into account, you simply need to design robots. That’s not enough.”

“We needed to ensure the animal’s health at all times, while also ensuring that the interactive installation would attract a global (human) audience.”

“Many factors were considered in this, including the design of the enclosure, the robot and its underlying systems, the different roles of the humans, and of course the selection of the cat.”

The authors announced their results in CHI 2024 meeting in Honolulu, Hawaii.

TikTok sensation Cat Janis passes away at the age of 31

Cat Janis, the singer who gained fame on TikTok for dedicating her final song to her son, has passed away from cancer, as announced by her family on Wednesday.


Her family announced The news was shared on her Instagram account: “This morning, from her childhood home, surrounded by her loving family, Katherine peacefully entered the light and love of her Heavenly Creator.

“We are forever grateful for the outpouring of love that Duchess Kate and our family have received over the past few months. Kat has seen her music go places she never expected. I am resting with the peace of mind that I will continue to provide for my son through music. None of this would have been possible without your support.”

Janice had sarcoma cancer, a rare type that affects bones and soft tissues. She passed away at the age of 31.

Janice documented her cancer journey on TikTok, revealing that she discovered a lump on her neck in November 2021, which later turned out to be cancer. Despite announcing she was cancer-free in July 2022, it returned in her lungs, leading her to hospice care last month.

Proceeds from Janice’s viral song were dedicated to her son after she learned about her impending death.

Her song “Dance You Outta My Head,” released on January 19th and dedicated to her youth, topped the TikTok Billboard Top 50 chart and made it into the Top 10 on Billboard’s Hot Dance/Electronic Songs chart. The song garnered over 12 million streams worldwide on Spotify.

“I transferred all the rights to my songs to my son so that I could leave him something. I don’t have much,” the singer wrote in a video Posted on TikTok on January 15th, urging fans to save this song for the future.

In her final TikTok video, Janice expressed her strength and mentioned feeling trapped due to her health, looking forward to dancing with God in heaven.

Most cats at cat shows found to be lounging around

intentional cat-likeness

Will cats continue to adopt their famously adorable, overbearing “cat-like” demeanor when forced to endure tons of attention from an enthusiastic public? Simona Cannas and colleagues at the University of Milan in Italy have produced some data that may draw attention to this question.

Their research, “Evaluation of cat behavior during cat shows” was published in the Veterinary Behavior Journal, focusing on the 82 cats at the cat show. (Researchers use technical terminology to describe the event as a “feline exposition.”)

They collected the data with great care. “An observer stood in front of the cage once every hour from 10:00 to 17:00, a total of 8 times for each cat.”

“An analysis of the behavior exhibited by cats on the day of the fair revealed that most of the cats were sleeping (93.9%), resting (62.2%), and looking at their surroundings (92.7%).”

The researchers’ conclusions are still up for debate as to what these cats had in mind. The study concluded that “the cat show environment represents a stressful and stimulating situation for cats. Nevertheless, our results identified few behaviors that cause discomfort or stress. Hmm…further research is needed to confirm and deepen our results.”

What a thread

Very long and thin things make a huge difference in what is possible depending on the length-to-thin ratio that catches the eye of mathematicians.

According to a press release, Researchers at North Carolina State University welcome the development of a “filamentary supercapacitor.” The name comes from the fact that the device is thread-like and can act as a capacitor, storing and releasing electrical charge in a controlled manner. The press release quotes Wei Gao, co-inventor of the technology.

She said: “Imagine being able to make a thread, a regular textile thread, that also becomes a battery. You can basically hide it in your clothes. You will be able to add additional functionality.”

We may be entering an era of thin technology.

As Feedback pointed out (October 1, 2022), the new city planned as part of Saudi Arabia’s Neom project is designed to be 170,000 meters long and 200 meters wide. Could North Carolina’s filamentous supercapacitor technology be integrated into the exoskeletons of Saudi Arabia’s cities? It would be a dramatic leap into the future for a country that claims to want to break away from its current economic dependence on oil.

This suddenly almost plausible possibility is indicative of the foresight of former Duchess of Windsor Wallis Simpson, who wrote almost a century ago that “one can never be too rich or too thin.” He is said to have said.

Measuring addiction

The old saying “If it can be measured, it must be important” has haunted many research efforts to explain why it is important to measure two out of five fingers on a person’s hand. Specifically, the second and fourth fingers. The two-finger quest is similar to addiction in a way. In some cases, this exploration considers addiction itself, perhaps better understood by measuring fingers.

Typically, explanations for finger proportions have spread in vague form, with the idea that hormone levels in the womb before birth somehow explain the relative length of a person’s fingers years later.

There are many and imaginative studies focusing on finger ratios. The types of important mysteries that researchers are trying to explain vary widely.

How diverse is it? Here we introduce some of the themes that have been addressed in numerical ratio research published in recent years. “Hunting success among Hadza hunters.” University students’ religious beliefs. “Parental income disparity and children’s digit ratio.” Artistic ability. “Age at first marriage among semi-nomadic people in Namibia.” “Psychological characteristics in a sample of cave explorers.” A bite wound caused during a fight. “Management Skills of Managers Employed in Public and Private Organizations in Udaipur City”; and “Number of Sex Partners”.

And addiction. Mehmet Gülcan Gülok and his colleagues from various institutions in Turkey recently published “Second to fourth digit (2D:4D) ratio for heroin and cannabis addicts” in the Journal of Ethnicity in Drug Abuse. Like most digit ratio studies, this one was done with great care. “We took the subject’s 2D and 4D lengths using a sensitive caliper and calculated 2D:4D.” And as always, it’s full of promise. “Our findings seem promising regarding whether prenatal hormonal factors are important in the pathogenesis of addiction.”

denver sniff test

If something and the headline seems odd, it might be worth considering. Anyone who stumbles across a gruesome study by an American environmental scientist may initially react to the ambiguity of its title. “Assessing the environmental justice aspects of odor in Denver, Colorado“.

Did that title have a solemn meaning? Is it really interesting? Both? No matter what the intent, Feedback is a tribute to the creator. Their language appealed to Mason Porter’s olfactory and linguistic sensibilities and alerted us.

New Species of Tabby Cat Discovered by Scientists

In 2013, Oncilla (Hyōmon)a species of small spotted cat native to the Americas; the northern tabby cat (Hyōmon) and southern tabby cat (Hyōmon). A new study led by the University of Maranhão has shown that Oncilla is actually three different species.

Cloudy tabby cat (leopardus pardinoides). Image credit: Johannes Pfleiderer.

The oncilla is a wild cat about the size of a domestic cat that lives in the mountains and rainforests of Costa Rica, Brazil, and Argentina.

These creatures, also known as tabby cats, Margaise (Hyōmon) and Ocelot (Hyōmon)but they are small, with slender builds and narrow muzzles.

They weigh only 1.5 kg, but usually do not exceed 3 kg, with males being slightly larger than females. The body length is 35-60cm and the height is about 25cm.

Oncilla has a yellowish-ochre background fur with a pattern of mainly open rosettes.

They eat small mammals, lizards, birds, eggs, invertebrates, and sometimes even tree frogs.

They typically live between 10 and 14 years in the wild, but have been known to live up to 23 years in captivity.

They are threatened by habitat loss from cattle ranching, agriculture, and the local pet trade.

Tadeu de Oliveira, a researcher at the University of Maranhão, and his colleagues say: “The tabby cat species group is the progenitor of an ancient classification system and one of the most intriguing, mysterious and fascinating groups of cats. “It is,” he said.

“Due to the limited knowledge available, the tabby cat has long been subject to several preconceptions regarding its range and associated habitats, both before and after species divergence. These include: and its presence in the Pantanal.”

“As it stands, the tabby cat species complex currently consists of two species. Hyōmon and Hyōmonthe former is further divided into three subspecies. Leopardus tigrinus oncilla, Leopardus tigrinus pardinoidesand leopardus tigrinus tigrinus” they added.

Hyōmon and Hyōmon Both are currently defined as globally endangered species. ”

“They live in some of the most endangered ecoregions and biodiversity hotspots in the Americas, including the Cerrado, the tropical Andes, the Atlantic Forest, and the Talamanca Mountains.”

“As an exception, leopardus tigrinus tigrinus, there are no published conservation priority areas for entities within the complex. ”

“Given the endangered status of these species and the high rates of habitat loss within their respective ranges, it is unlikely that viable populations of these species will exist. It is essential to identify areas with high levels.”

Typical examples of tabby cat species complexes: (a) Savannah tabby cat (Hyōmon); (b) Cloudy tabby cat (leopardus pardinoides); (c) Atlantic Forest tabby cat (Hyōmon). Image credit: Ricardo Ribeiro / Johannes Pfleiderer / de Oliveira other., doi: 10.1038/s41598-024-52379-8.

In their study, the authors sought to determine the actual distribution range of tabby cat species and subspecies, compare their characteristics, and assess similarities and differences between them.

Ultimately, they aimed to characterize tabby cats and determine the actual number of the species.

“Our results revealed the existence of a cryptic species, the Claudi tabby cat (leopardus pardinoides), which includes both Leopardus tigrinus oncilla and Leopardus tigrinus pardinoides,” they said.

According to the team: leopardus pardinoides It is a long-tailed cat with short rounded ears and weighs 2.27 kg.

This new species has a strikingly margay-looking head with a rich reddish/oranged/gray-yellow background color and is adorned with irregularly shaped medium to large 'cloudy' rosettes. , with dense, soft fur, strongly marked and often coalesced.

The characteristic is LEopardus pardinoides There is only one pair of breasts/nipples.

This species is found in the extinct cloud forests of southern Central America and the Andes, usually above 1,500 meters above sea level, especially between 2,000 and 3,000 meters, in subtropical/temperate climates with mild temperatures and very abundant precipitation. You can see it. Usually located in areas where ocelot numbers are low or non-existent.

leopardus pardinoides “Distributed along 11 mountain ecoregions,” the researchers said.

“In Central America, it is restricted to the Tilaran Mountains, Central Volcanic Mountains, and Talamanca Mountains (Talamancan Mountains Forest ecoregion) in Costa Rica and Panama and the eastern montane forests of Panama.”

“The lowland rainforests and wetlands of the Atrato River basin of the Choco Darien ecoregion are the main barrier between the populations of the brown tabby cat in eastern Panama and the Andes, while in the north the species is restricted to the Isthmian Atlantic rainforest. limited by.”

“In South America, its range extends from the Andean forests of Venezuela through the eastern, central, and western mountain ranges of Colombia to Ecuador, through Peru, Bolivia, and the Yungas Forest ecoregion of the southern Andes, and ends in northwestern Argentina.”

“The core area of ​​its distribution is in Colombia, but it also extends to Ecuador.”

of the team result appear in the diary scientific report.

The specimen is very well preserved, showing a complete hemimandible and all teeth except the incisors.

It is very complete and in very good preservation, providing very interesting information for making paleoecological inferences about this new feline.

“We recovered a nearly complete jaw with almost all teeth preserved in exceptional condition,” Dr. Siliceo said.

“What was most surprising was that underneath it was a small second molar, a tooth that does not exist in all modern and fossil cats. pro airlus

The Saber-Toothed Cat and the Direwolf: Prehistoric Predators

Researchers found high rates of osteochondrosis in the joints of Ice Age saber-toothed tigers and dire wolves, based on more than 1,500 limb bones examined from the La Brea Tar Pits. This study suggests a potential link between the health problems of these ancient species and those of modern livestock. Credit: SciTechDaily.com

Studies have found that the incidence of osteochondrosis in these extinct predators is surprisingly high.

Ice Age saber-toothed tigers and direwolves had higher rates of bone disease in their joints, according to a recent study published in an open access journal. Pro Swan By Hugo Schmökel and colleagues at the Evidencia Academy in Sweden.

Ancient species of osteochondrosis

Osteochondrosis is a developmental bone disease known to affect joints. vertebrateincluding humans and various domestic animals. seed. However, the disease is not well documented in wild species, and published cases are extremely rare. In this study, Schmökel and colleagues identified signs of the disease in fossil limb bones of Ice Age saber-toothed tigers. (Smilodon fatalis) and dire wolf (Aenosion Dyras) Approximately 55,000 to 12,000 years ago.

Research results from the La Brea Tar Pits

Researchers examined more than 1,000 limb bones of saber-toothed tigers and 500 limb bones of dire wolves taken from the late Pleistocene La Brea Tar Pits, and found that many bones contained dissecting bones. They discovered small defects that matched certain symptoms of a bone disease called osteochondrosis (OCD). These defects were primarily found in the shoulder and knee joints, and their incidence was as high as 7% of the bones examined, significantly higher than that observed in extant species.

Implications and future research

Because this study was limited to bones isolated from a single fossil locality, further research on other fossil sites will reveal patterns of prevalence of the disease and from there provide insight into the lives of these animals. aspects may be clarified. For example, it remains unclear whether problems with these joints hindered the hunting ability of these predators. Additionally, OCD is common in highly inbred modern domestic dogs, so the high incidence of this disease in these fossil animals could be a sign that populations are declining as these ancient species approach extinction. It may be.

Connection with modern animals

The authors add: “The study adds: Smilodon Direwolf paleopathology made possible by La Brea Tar Pits & Museum’s unparalleled large sample size. This collaborative research between paleontologists and veterinarians shows that these animals, despite having survived harsh times and are now extinct large predators, share diseases with the dogs and cats in our homes today. It confirms what I was holding. ”

NASA Transmits Cat Video 31 Million Kilometers into Space

Video of cat Taters chasing laser light sent from space

NASA

NASA has broken its own record by transmitting ultra-high-definition video from deep space to a distance of 31 million kilometers. The video was not of a distant celestial body or spaceship, but of a cat called Tater chasing the light from a laser pointer.

Abhijit Biswas NASA’s Jet Propulsion Laboratory (JPL) speaks new scientist Taters were selected for the first transmission at that distance.
first television test broadcast Also featured was a cat, Felix, a cartoon feline. Lasers He says the inclusion of his pointers is a visual reflection of the use of lasers in transmission.

“Apparently this cat really likes chasing laser pointers, and somehow it all came together in this video,” Biswas said.

The 15-second video was sent by NASA.
Deep Space Optical Communications (DSOC) The experiment was carried out aboard the Psyche spacecraft, which was launched in October to intercept the asteroid of the same name.

DSOC is really a proof of concept and I hope everyone believes that this can be done. This technology is already being used to transmit data between the Moon and Earth, but only over a distance of 384,400 kilometers. He said it should be possible to test longer distances than the Taters test in the future.

One problem is making sure the laser light is aimed precisely at the receiving station. “It’s a very narrow beam. At the distance Psyche is now, it [is] just a few hundred kilometers [wide by the time it reaches Earth]” says Biswas. “So if you take the slightest turn, you’ll end up in the Pacific Ocean or somewhere else. You’ll miss it completely. So there was a lot of anxiety about that.”

The video was transmitted at near-infrared wavelengths by a laser transceiver and took 101 seconds to travel from the spacecraft to Earth. The 267 Mbit/s message was received by the following equipment:
hale telescope After being filmed at Palomar, it was transmitted via the Internet to JPL in Southern California, where the video was played in real time. This data rate makes DSOC faster than most national broadband connections.

The Consequences of a Fat Cat: The Perspectives of Scientists

by

A study from the University of Illinois at Urbana-Champaign revealed the effects of overfeeding on cats’ digestive systems and gut microbiota. The study involved 11 cats and showed that an unrestricted diet led to significant weight gain, changes in gastrointestinal transit time, and changes in fecal microbiota and acidity. These findings contribute to the understanding of obesity in pets and inform weight management strategies such as feeding restriction and promotion of physical activity.

Cat owners want their pets to be happy, but overfeeding can have unintended consequences. The prevalence of obesity in cats is increasing, impacting their health, lifespan, and overall well-being. A new study from the University of Illinois at Urbana-Champaign looks at what happens to cats’ digestive systems and gut microbiota when they overeat.

“About 60% of cats in the United States are overweight, which can lead to health problems such as diabetes and chronic inflammation. A lot of research has been done on weight loss in cats; “There has been little focus on the reverse process. In this study, we wanted to learn more about the metabolic and gastrointestinal changes that occur as a result of overeating and weight gain in cats,” said study co-author and author of Animal Science said Kelly Swanson, professor and interim director of the department. The Department of Nutritional Sciences (DNS), part of the U of I College of Agricultural, Consumer, and Environmental Sciences (ACES).

Methodology and initial findings

The study included 11 spayed adult cats. They were fed standard dry cat food and allowed to eat as much as they wanted after 2 weeks of baseline measurements. Researchers regularly took blood and fecal samples and monitored physical activity.

Once the cat was able to overeat, her food intake immediately increased significantly and she began to gain weight. The mean body condition score (BCS) at the start of the study was 5.41 on a 9-point scale. After 18 weeks of overeating, the weight increases to 8.27, which corresponds to 30% overweight. According to Swanson, BCS corresponds to a person’s body mass index (BMI), and anything above 6 is considered overweight.

NASA’s Laser Technology Beams Ultra-HD Cat Video from 19 Million Miles Away

NASA has made a significant advancement in deep space communications by successfully transmitting high-definition video from 19 million miles away. This breakthrough paves the way for advanced data transmission in space exploration. The video was transmitted from a cat named Taters and marked a historic milestone for NASA’s laser communications demonstration.

The Deep Space Optical Communications Experiment on December 11 transmitted ultra-high-resolution streaming video from a record-setting distance of 19 million miles. This milestone is part of a NASA technology demonstration aimed at streaming extremely high-bandwidth video and other data from deep space to enable future crewed missions beyond Earth orbit.

NASA Deputy Administrator Pam Melroy stated, “This achievement confirms our commitment to advancing optical communications as a key element in meeting future data transmission needs. Increasing bandwidth is essential to achieving future exploration and science goals, and we look forward to continued advances in this technology and the transformation of how we communicate during future interplanetary missions.”

The 15-second test video was transmitted using a Flight Laser Transceiver at a maximum bit rate of 267 Mbps and took 101 seconds to reach Earth. The instrument transmitted a coded near-infrared laser to the Hale Telescope at the Palomar Observatory, where it was downloaded. Each frame of the video was transmitted “live” to NASA’s Jet Propulsion Laboratory in real time.

The video was sent via a Deep Space Optical Communications (DSOC) technology demonstration flight laser transceiver that was installed at NASA’s Jet Propulsion Center in April 2021 and later integrated with NASA’s Psyche spacecraft. The technology aims to transmit data from deep space 10 to 100 times faster than the most advanced radio frequency systems used in today’s deep space missions.

The ultra-high-definition video features a cat named Taters and was transmitted from deep space on December 11, 2023. The video was part of a technology demonstration known as Deep Space Optical Communications (DSOC) as the Psyche spacecraft heads towards the asteroid belt between Mars and Jupiter.

The system has demonstrated faster data downlink speeds and increased pointing accuracy during weekly checkouts. The project demonstrated downlink bit rates of 62.5 Mbps, 100 Mbps, and 267 Mbps, comparable to broadband Internet download speeds. The team was able to download a total of 1.3 terabits of data during that time, marking a significant technological achievement.
