Dogs News -- ScienceDaily Veterinary research and news on dogs as companions, canine health, wolf pack behavior and more. If it is news about dogs, you will find it here! These frozen wolf cubs ate a woolly rhino?and changed what we know about dogs Two Ice Age wolf pups once thought to be early dogs have been identified as wild wolves, thanks to detailed DNA and chemical analysis. Surprisingly, their last meals included woolly rhinoceros meat?an unusually large prey item?hinting that ancient wolves might have been bigger than today?s. Their well-preserved bodies also shed light on wolf pack behavior and Ice Age environments. Defying Darwin: Scientists discover worms rewrote their DNA to survive on land New research is shaking up our understanding of evolution by revealing that some species may not evolve gradually at all. Instead, scientists discovered that certain marine worms experienced an explosive genetic makeover when they transitioned to life on land over 200 million years ago. Their entire genome broke into pieces and was randomly reassembled an event so extreme it stunned researchers. This radical shift supports the theory of "punctuated equilibrium," where species remain unchanged for ages and then suddenly leap forward. Telehealth can improve care for cats with chronic health issues UC Davis researchers found that video telehealth visits help cat owners better care for arthritic cats without the stress of clinic visits. Owners appreciated personalized tips to improve their cat s comfort at home, and most said they'd pay for this convenient service. It s a game-changer for supporting cats with chronic conditions in a low-stress, familiar setting. HIV discovery could open door to long-sought cure New HIV research shows that small changes in the virus affect how quickly or slowly it replicates and how easily it can reawaken in the body. These insights bring researchers closer to finding ways to flush out the dormant virus and eliminate it for good. Genetic basis of purring in cats Whether you are lucky enough to have a cat companion or must merely live this experience vicariously through cat videos, Felis catus is a familiar and comforting presence in our daily lives. Unlike most other feline species, cats exhibit sociality, can live in groups, and communicate both with other cats and humans, which is why they have been humans' trusted accomplices for millennia. Despite this intimacy, there is still much that we don't know about our feline friends. Horses 'mane' inspiration for new generation of social robots Interactive robots should not just be passive companions, but active partners -- like therapy horses who respond to human emotion -- say researchers. Coastal Alaska wolves exposed to high mercury concentrations from eating sea ... Scientists show that wolves that are eating sea otters in Alaska have much higher concentrations of mercury than those eating other prey such as deer and moose. Zika virus uses cells' 'self-care' system to turn against host A new study reveals the biological secret to the Zika virus's infectious success: Zika uses host cells' own 'self-care' system of clearing away useless molecules to suppress the host proteins that the virus has employed to get into those cells in the first place. Modulation of antiviral response in fungi via RNA editing The molecular pathways involved in antiviral defenses and counter-defenses in host-pathogen systems remain unclear. Researchers have used Neurospora crassa as a model organism to explore how RNA editing influences fungal antiviral responses. They identified two neighboring genes -- an RNA-editing enzyme (old) and a transcription factor (zao) -- that regulate virus-induced gene expression. Their findings show how the old-zao module controls both asymptomatic and symptomatic infections, providing new insight into conserved antiviral mechanisms in fungi. Bees facing new threats, putting our survival and theirs at risk A new report identifies the top 12 emerging threats that could accelerate pollinator losses within the next 5-15 years, according to ten of the world's leading experts. Genome of near-extinct northern white rhino offers hope for reviving the species The northern white rhinoceros is one of the rarest animals on Earth, with just two females left and no natural way for the species to reproduce. Now, scientists have mapped the entire genome of a northern white rhino. This represents a crucial step toward bringing the critically endangered species back from the edge using advanced reproductive technologies. The complete genome can be used as a reference to analyze the health of previously developed northern white rhinoceros stem cells. Eventually, those stem cells may be able to generate sperm and eggs to yield new rhinos. With AI, researchers predict the location of virtually any protein within a h... Researchers developed a new machine learning method that, given a relevant amino acid sequence, can automatically predict the location of a protein in any human cell line down to the single-cell level. This advance could help clinicians identify certain diseases, streamline the process of drug discovery, and give biologists new insights into the effects of protein mutations. 'Loop'hole: HIV-1 hijacks human immune cells using circular RNAs Researchers have identified a never-before-seen mechanism that enables HIV-1 to evade the body's natural defenses and use it to support its survival and replication. The 'loophole' is a biological process that involves circular RNAs and marks the first experimental evidence of HIV-1 generating them from an integrated retroviral genome. Findings point to a novel strategy the virus uses to survive, providing a new target in the fight against one of the world's most resilient pathogens. Evidence of mother-offspring attachment types in wild chimpanzees A team of researchers has identified distinct mother-offspring attachment types in wild chimpanzees (Pan troglodytes verus). Drawing parallels with human psychology, the study provides compelling evidence that wild chimpanzee infants, like human children, develop critical secure and insecure-avoidant attachment patterns to their mothers. However, unlike humans and some captive chimpanzees, wild chimpanzees did not exhibit disorganized attachment characterized by high rates of aggression. This raises new questions about how this type of attachment may be shaped by survival and modern environmental pressures. Novel, needle-free, live-attenuated influenza vaccines with broad protection ... A research team has achieved a significant breakthrough in developing broadly protective, live-attenuated influenza vaccines (LAIV). These innovative LAIV platforms offer potential to develop universal influenza vaccines that induce a more robust immune response against various virus subtypes, including both human and avian strains.
