:huh: DENVER, Colorado (AP) -- Scientists for the first time have cloned a dog.

Researchers nicknamed their cloned pal Snuppy, which is shorthand for "Seoul National University puppy." One of the dog's co-creators, Gerald Schatten of the University of Pittsburgh School of Medicine, describes their creation, now 14 weeks old, as "a frisky, healthy, normal, rambunctious puppy."

Researchers congratulated the Korean team on improving techniques that might someday be medically useful. Others, including the cloner of Dolly the sheep, renewed their demand for a worldwide ban on human reproductive cloning.

"Successful cloning of an increasing number of species confirms the general impression that it would be possible to clone any mammalian species, including humans," said Ian Wilmut, a reproductive biologist at the University of Edinburgh, who produced Dolly nearly a decade ago.

"The ability to use the underlying technology in developing research models and eventually therapies is incredibly promising," said Robert Schenken, president of the American Society for Reproductive Medicine. "However, the paper also points out that in dogs as in most species, cloning for reproductive purposes is unsafe."

The experiment's outcome only seems to buoy the commercial pet-cloning industry, which has charged up to $50,000 (euro41,000) per animal. The first cloned-to-order pet sold in the United States was a 9-week-old kitten produced by the biotech firm, Genetic Savings & Clone Inc. of Sausalito, California.

Company officials said they expect to commercially clone a dog within a year using eggs collected from spaying procedures at veterinary clinics. The South Korean researchers can surgically remove eggs from research animals with fewer regulations than in the United States.

But the dog cloning team tried to distance its work from commercial cloning. "This is to advance stem cell science and medicine, not to make dogs by this unnatural method," Schatten said.

On scientific terms, the experiment's success was mixed. More than 1,000 cloned embryos were implanted into surrogate mothers and just three pregnancies resulted. That's a cloning efficiency rate lower than experiments with cloned cats and horses. Details appear in Thursday's issue of the journal Nature.

Like Dolly and other predecessors, Snuppy was created using a method called somatic cell nuclear transfer, or SCNT.

Scientists transfer genetic material from the nucleus of a donor adult cell to an egg whose nucleus -- with its genetic material -- has been removed. The reconstructed egg holding the DNA from the donor cell is treated with chemicals or electric current to stimulate cell division.

Once the cloned embryo reaches a suitable stage, it is transferred to the uterus of a surrogate where it continues to develop until birth.

Dog eggs are problematic because they are released from the ovary earlier than in other mammals. This time, the researchers waited and collected more mature unfertilized eggs from the donors' fallopian tubes.

They used DNA from skin cells taken from the ear of a 3-year-old male Afghan hound to replace the nucleus of the eggs. Of the three pregnancies that resulted, there was one miscarried fetus and one puppy that died of pneumonia 22 days after birth.

That left Snuppy as the sole survivor. He was delivered by Caesarean section from his surrogate mother, a yellow Labrador retriever.

Researchers determined that both of the puppies that initially survived were genetically identical to the donor dog.

Schatten said the Afghan hound's genetic profile is relatively pure and easy to distinguish compared to dogs with more muddled backgrounds. But dog experts said the researchers' choice of breed choice was disquieting.

"The Afghan hound is not a particularly intelligent dog, but it is beautiful," said psychologist Stanley Coren, author of the best-selling manual "The Intelligence of Dogs." He ranked the Afghan hound last among 119 breeds in temperament and trainability.

"Many people who opt for the cloning technique are more interested in fashionable looks," he said. "Whenever we breed dogs for looks and ignore behavior, we have suffered."

This technology could save a lot of species from extinction! :)

Hopefully used for good, rather than evil.

Tell me how many uses there are for evil cloning? You mean like cloning a celebrity and selling nude pictures to some paparazzi for a great money sum? :rofl:

while this has many good benefits like saving a species from extinction i can not see using it on dogs or cats. You are cloning something that WILL NOT be your best friend. it will look like it but it will never have the same thoughts or memories that made it the animal you came to know (this is besides the soul thing which i do not take a stand one way or the other). You have changed as a person over the years and whats to say that the world or you wont change the new pet and make it a different animal then the one you came to love.

Theres also the money issues involved like why dont you get over your loss and move on and donate the money to a good cause. your pet would probably have wished you to not waste the money bringing himself or herself back and it would probably like you to take home an animal from a shelter that would likely be put to sleep. If your so destraut that you can not take home a new pet (i respect that) then donate the money to the a local shelter. Or put it to some good use for you or for another donate it to an opranige or charity or maybe if you dont wish to do that spend it on something for yourself, you will never be able to bring back the pet you lost so you might as well NOT attempt to create something that looks the same because it wont be the same in its mind.

    • The laptop in the bedroom is an Acer with i7-10510U CPU. Acer's website states they will not be upgrading it so I had little choice other than disable secure boot. I know next to nothing on these matters so hopefully it will be fine.
    • GitHub removes manual model selection from Copilot free and student plans by Karthik Mudaliar GitHub is removing the ability to manually select an AI model from its Copilot Free and Student plans, making its automatic routing system the default and only way to choose a model. This means users on these tiers will no longer be able to deliberately select a particular OpenAI, Anthropic, Google, or Microsoft model for a task. In its announcement, GitHub said Copilot Auto will dynamically choose what it considers the best model for each request. Free and Student accounts will retain access to models from multiple families, although the available selection will continue to depend on the restrictions attached to each plan. GitHub did not identify a fixed pool of models that Auto will always use, and its documentation warns that model availability can change over time. GitHub describes Auto as more than a random fallback system. On supported surfaces, its task-optimization technology evaluates the complexity of a request alongside real-time information about model health and availability. Straightforward prompts can be routed to faster and less expensive models, while more demanding coding tasks may be sent to higher-cost reasoning models. The company says this approach should reduce rate limiting, latency, and failed requests. Auto generally selects one model along natural prompt-caching boundaries rather than repeatedly switching models during a session, as GitHub found that mid-session changes increased costs without producing sufficient improvements in output quality. Users can still check which model generated a response. In Copilot Chat, the information appears when hovering over an answer, while Copilot CLI and the Copilot cloud agent display the selected model alongside their output. Auto is available in Copilot Chat, Copilot CLI, and the cloud agent, with the exact implementation and release status varying between supported development environments. The latest restriction follows several months of adjustments to Copilot’s individual plans. GitHub temporarily halted new Pro, Pro+, and Student subscriptions in April as it sought to manage demand and service reliability. It later introduced token-based billing and began gradually reopening individual-plan registrations on June 17. Alongside the picker change, GitHub is retiring the “Preview” label from Microsoft-developed models. It argues that the label is no longer necessary because Auto handles model routing and models are continuously updated behind the scenes.

    • Google reportedly set to lose two key Gemini and DeepMind researchers to Anthropic by Karthik Mudaliar Google is reportedly preparing to lose two more prominent artificial intelligence researchers, with Gemini contributors Jonas Adler and Alexander Pritzel planning to join rival AI developer Anthropic. According to a report from Bloomberg, both researchers are viewed internally as important contributors to Google’s flagship Gemini model family. Adler worked on Google’s AI coding efforts, while Pritzel was involved in the process used to train AI systems. Neither company has publicly confirmed the moves. The report also does not say when the researchers will formally leave Google or what positions they will hold at Anthropic. Training a large AI model requires decisions covering its architecture, data preparation, distributed computing infrastructure, and post-training methods that shape how the finished system behaves. Researchers with experience operating at the scale of Gemini are consequently difficult to replace quickly. Both Adler and Pritzel have previously contributed to Google DeepMind’s scientific research as well. They are listed among the authors of the company’s work on expanding AlphaFold protein-structure predictions across entire proteomes, alongside AlphaFold researchers including John Jumper. The reported departures arrive shortly after another important change within Google’s Gemini organization. Gemini co-lead Noam Shazeer is leaving Google for OpenAI, after returning to the search company in 2024 through its deal with Character.AI. Shazeer is particularly well known as one of the authors of the Transformer paper, whose architecture became the foundation for most modern large language models. Anthropic, meanwhile, has been recruiting recognizable figures from other leading laboratories. OpenAI co-founder and former Tesla AI director Andrej Karpathy joined Anthropic’s pre-training team in May. His move, followed by the reported recruitment of several Google researchers, suggests Anthropic is strengthening the research teams responsible for the core capabilities of future Claude models rather than concentrating solely on product and enterprise sales. The competition is complicated by the companies’ extensive commercial relationships. Anthropic competes directly with Google’s Gemini models, but it also relies on Google as an infrastructure partner. In April, Anthropic announced an expanded agreement with Google and Broadcom covering multiple gigawatts of next-generation Tensor Processing Unit capacity. TPUs are Google-designed accelerators used to train and run large AI models. via Bloomberg
