AMD tipped to provide chips for PS6, new PlayStation handheld and the next Xbox
A couple of weeks ago, the YouTuber Moore's Law is Dead posted a video on the unannounced AMD Zen 6 APU codenamed "Magnus" that would reportedly power the next Xbox or PlayStation 6. Now, he's returned with an update that confirms Magnus will power the new Xbox, while two different AMD APUs are alleged to feature in the PS6 and a PlayStation handheld. There is a lot of speculation in the update surrounding various codenames and Shakespearean characters. I'll break it down below plus details on what AMD's next APU could look like. According to Moore's Law is Dead, there are two groups of codenames that could be the PS6 and a potential handheld; Orion and Canis or Robin and Robin Plus. In the former set, Orion is the codename for the PS6 and Canis would power the handheld. Another known console leaker, Kepler L2 seemed to confirmed the Canis naming convention on the NeoGaf forums. They also claimed in another post that Canis has a monolithic design, meaning that the single silicon would contain the CPU and GPU on the on the same node. Different compared to say the AMD Ryzen SoC which has multiple smaller dies or chiplets connected to one another. The Robin/Robin Plus moniker is interesting in so far that AMD reportedly uses Shakespearean characters as codenames for PlayStation chips. For the PS5 the company allegedly used Oberon and Oberon Plus. Robin is a character from A Midsummer Night's Dream, though Puck would be the more well known name. Sony and AMD did recently announce a partnership for the next PlayStation console. It should be powerful, as we recently reported that the next Sony console could utilize up to 24GB of RAM. Currently, the PS5 uses 16GB of RAM. Get instant access to breaking news, the hottest reviews, great deals and helpful tips. With the PlayStation out of the way, the AMD Zen 6 APU that Moore's Law is Dead leaked in mid-July has some more details now. THe APU will reportedly have a 3nm RDNA "AT2 GPU die and will have a 192-bit memory bus, and not the 384-bit bus that was revealed earlier, which would be smaller than the 320-bit bus on the Xbox Series X. Though we've seen speculation that AMD might split the bus. Previously, it was alleged that Magnus would feature 11 CPU cores, with three Zen 6 cores and eight Zen 6 cores. Microsoft and AMD announced in June that the companies were partnering on the future of Xbox gaming including improving Xbox Cloud Gaming. We should see more of this future when Xbox and Asus show off the ROG Xbox Ally which features an AMD Ryzen Z2 chip in the handheld console.

Meet the largest living wild dogs in the world
If you've ever stayed in a cabin in the forest, you'd know there's nothing more haunting than a wolf's howl echoing through you in the middle of the night. And if it were a grey wolf you were up against, your chances would be slimmer than your dream body. Grey wolves (aka Canis lupus) are the largest wild dogs in the world, and have roamed the northern hemisphere for thousands of years. But behind the folklore and fear lies a surprisingly misunderstood species, one whose intelligence, loyalty, and endurance deserve a second look. Grey wolves are the biggest living members of the dog family. As Encyclopaedia Britannica notes, they're the 'largest nondomestic member of the dog family.' Adult males can weigh anywhere from 30 to 80 kilograms (66–175 pounds) and stretch over 6 feet in length, including their thick, bushy tail. Their large paws and double coat of fur allow them to survive everything from arctic chills to mountain winds. But wolves aren't just built for the cold. They're also made for motion. According to Smithsonian Magazine, wolves can travel more than 20 miles a day looking for food, often working in tight-knit packs that operate with remarkable strategy and discipline. Grey wolves are the wild ancestors of every dog we know and love today, from a pampered pug to a fearless German shepherd. As Britannica points out, domestication began in northern Eurasia over 15,000 years ago, with early humans and wolves forming a bond that changed the course of both species. But unlike the dogs lying under our desks or curled up on couches, wolves still live by the rules of the wild. They are territorial, cautious of humans, and intensely loyal to their packs. Their howls are a form of long-distance communication, rallying cries, and territorial warnings. In the 20th century, wolves were nearly wiped out in many regions. Seen as a threat to livestock and safety, they were hunted relentlessly. But in 1995, something remarkable happened: wolves were reintroduced into Yellowstone National Park. These wolves then began to reshape the entire ecosystem, helping control overgrown elk populations. The ripple effect, known as a trophic cascade, even changed the flow of rivers. Yes, wolves can do that. Even now, grey wolves walk a fine line between protection and persecution. Their population status and legal rights often change, depending on political climates and public opinion. While Britannica notes that about 65,000–78,000 wolves live in North America, their future remains uncertain in many regions. Still, wildlife experts continue to remind us: wolves aren't villains. They're keystone species, vital to the balance of nature, and not just the survivors but also the engineers of our ecosystems, and the very root of our bond with dogs.

Meet the wild dog with the highest hunting success rate in the world
When people think of top predators in the wild, lions, leopards, or wolves usually come to mind. These iconic hunters are often seen as the kings and queens of the food chain. But there's another predator, less famous yet exceptionally efficient, that outperforms them all when it comes to successful hunts. Often overshadowed by bigger or more charismatic carnivores, African wild dogs are one of nature's most effective hunters. These wild dogs are well known for their speed, strategy, and teamwork; they have evolved into exceptional predators that have the highest kill success rate among large carnivores. Despite their good hunting abilities, these animals remain one of Africa's most endangered species, struggling to survive in shrinking habitats and against fierce competition from larger carnivores. The apex predator with the most successful kills With their lean frames and oversized ears, African wild dogs may look harmless, but they are among the most lethal hunters in the wild. According to BBC Wildlife Magazine, they have a 'kill rate per chase of more than 85 percent,' which is far higher than the roughly 25% success rate seen in lions. This extraordinary efficiency is mostly due to their coordination and pack dynamics during hunts. A study conducted in Tanzania's Serengeti National Park revealed that pack size significantly affects hunting success. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Dolly Parton, 79, Takes off Her Makeup and Leaves Us Without Words The Noodle Box Undo According to the findings, 'the success of a pack... was influenced by the age of the prey and the number of dogs hunting together,' while factors like distance from prey or available cover didn't play much of a role. Solo hunters among wild dogs often brought down smaller prey like Thomson's gazelles. However, it took larger packs to tackle tougher targets. 'Groups of two did not hunt adult wildebeest successfully,' while bigger groups could even kill calves of blue wildebeests. The study also suggested that hunting in groups 'reduced interspecific competition from spotted hyenas… through improved defence of carcasses. ' Despite this efficiency, African wild dogs often lose their hard-earned meals to larger predators. 'They may lose half of their kills… to other carnivores such as hyenas and lions,' BBC Wildlife Magazine reports. Taxonomically, African wild dogs are unique. Though part of the Canidae family, they don't belong to the Canis genus like wolves and domestic dogs. As BBC explains, 'African wild dogs are now considered close to the base of the wolf-like canids,' making them evolutionary outliers. Yet, despite their remarkable hunting skills and social intelligence, African wild dogs are classified as Endangered. Their greatest challenge isn't the lack of prey, but habitat loss, human conflict, and competition from bigger carnivores.

Dogs may have domesticated themselves because they really liked snacks, model suggests
When you buy through links on our articles, Future and its syndication partners may earn a commission. Scientists don't know exactly how wolves were domesticated into early dogs, but it's possible that they domesticated themselves by choosing to coexist with humans so that, a new study finds, they could be fed consistently. Then, these snackish canines likely selected mates that did the same. While the theory is nothing new, the new research shows it's statistically possible for the wolves to have driven their own domestication into dogs through natural selection. Archaeological and genetic evidence suggests that dogs (Canis familiaris) are descended from gray wolves (Canis lupus) and became domesticated over two historical periods: between about 30,000 and 15,000 years ago when wild wolves were domesticated into early dogs, then from around 15,000 years ago to the modern era when these dogs became differentiated into breeds. These periods of domestication were driven by different evolutionary forces, according to a new study published Feb. 12 in the journal Proceedings of the Royal Society B. The second domestication period is thought to have been mostly driven by artificial selection: humans chose more tame wolves to accompany them for hunting and companionship, and purposely bred the least-wild animals together, which ultimately produced the tame species we know as the domestic dog. But the selective forces that drove the first domestication period are less clear. According to one hypothesis, wolves underwent "self-domestication": after prehistoric animals started coming to human settlements to scavenge for food scraps, they grew more accustomed to living near people. These more-tolerant wolves preferred a steady food supply over inconsistent sources in the wild, and their descendants gave rise to the first domestic dogs. Related: Smarter dogs have smaller brains, surprising study reveals A similar process is believed to have occurred with cat domestication, as research found that the ancestors of house cats spent time near farming communities around 10,000 years ago, before settling into a mutually-beneficial relationship in which they hunted and ate rodents in exchange for food. Scientists have long debated the dog self-domestication hypothesis. One criticism is that natural selection may not be able to work quickly enough to turn wild wolves into domestic dogs over thousands of years — without selective breeding by humans to speed the process up. In the new study, researchers addressed this question of time constraint by using a statistical model that considered potential timelines of dog domestication and gave its computerized canines some agency over choosing their lifestyle and mates. The model showed that over 15,000 years, natural selection could potentially drive dog self-domestication. But for this to happen, two conditions had to be met: Wolves had to choose to stay near humans to eat food scraps, and they had to select mates with a similar temperament. "When females were selecting mates, they also had to select males that had a similar tameness to themselves," study co-author Alex Capaldi, a mathematician and statistician at James Madison University in Virginia, told Live Science. "So if both of those processes are in play, then it is possible for the self-domestication hypothesis to beat the time constraint critique."

Dogs are the earliest animal to be domesticated, so studying their evolution can help scientists better understand how domestication may work in other species. And since the process of dog domestication was so closely linked to the development of early human societies — dogs herded cattle in early human settlements, and migrated with early humans to the Americas — understanding its timeline can illuminate our history, and how we ourselves evolved to communicate and bond with dogs.
