Chihuahuas have about 0.2 percent wolf ancestry, according to a new study. Breakthroughs, discoveries, and DIY tips sent every weekday. While that chihuahua might seem about as similar to a wolf as a shrub is to a mighty redwood tree, some small breeds like the tiny, big-eared chihuahua have some wolf ancestry. New research published today in the journal (), finds that the majority of dogs living today have low but detectable levels of post-domestication wolf ancestry. These genes have likely helped shape multiple characteristics, including personality traits, sense of smell, and body size.

Adults over 70 who regularly listen to music show 39% lower dementia risk while instrument players have 35% reduced risk, according to new Monash University research.

Ernest Shackleton knew'Endurance' had shortcomings, new study says Issues with the ship's hull, deck beams, and more show the ship was no match for Antarctic sea ice. The'Endurance' leaning to one side, during the Imperial Trans-Antarctic Expedition, 1914-17, led by Sir Ernest Shackleton. Breakthroughs, discoveries, and DIY tips sent every weekday. For almost 110 years, the has rested at the bottom of the icy waters of the Antarctic's Weddell Sea . Long held as the poster ship for Antarctic exploration, Sir Ernest Shackleton's ill-fated ship was no match for the crushing sea ice that sank it in November 1915 .

Breakthroughs, discoveries, and DIY tips sent every weekday. Your body is constantly generating new cells. In your digestive tract, the colon's lining turns over every five to seven days. Your red blood cells replace themselves every few weeks, skin cells about once a month. But certain organs are a big exception.

Scientists have uncovered hidden patterns in the Bible that challenge ancient beliefs about its origins. Using artificial intelligence, they discovered'fingerprints' in text throughout the Old Testament, suggesting multiple people wrote the stories. The traditional Jewish and Christian understanding is that Moses wrote the first five books of the Old Testament, including stories about creation, Noah's flood and the Ark of the Covenant. The new study found three distinct writing styles with distinct vocabulary, tone and focus areas, suggesting multiple authors and sources contributed to the books over time. Researchers used AI analyzed for 50 chapters across five books, uncovering inconsistencies in language and content, repeated stories, shifts in tone and internal contradictions.

The Ronald Reagan Presidential Library in Simi Valley, California, has opened "Dead Sea Scrolls: The Exhibition," featuring a collection of ancient Jewish manuscripts along with 200 other artifacts. The Dead Sea Scrolls may be even older than researchers thought, according to a new study driven by an artificial intelligence (AI) model. A group of researchers from the Netherlands, Italy and Denmark recently published their findings in the journal PLOS One on June 4. The researchers said they developed an AI-based date-prediction model named Enoch, a nod to the biblical patriarch of the same name. Enoch "was trained as a machine learning-based date-prediction model applying Bayesian ridge regression on established handwriting-style descriptors," according to the study.

Petco Love Lost is a free platform that uses AI-powered photo matching to reunite lost pets with their families. If your job has you feeling tense, your dog might be feeling it too. A new study published in Scientific Reports finds that stress from work can affect your dog at home. The research, led by Tanya Mitropoulos and Allison Andrukonis, shows that when dog owners dwell on work problems after hours, a habit known as "work-related rumination," their pets show more signs of stress. Researchers surveyed 85 working dog owners.

In the search for happiness, having a good day every day is surely crucial. But when there are so many pursuits competing for our attention, sometimes it's difficult to know how much time to allocate for each one. Now, scientists in Canada claim to cracked the code for the perfect day – and surprisingly, it includes a short shift at work. According to the experts, the formula for the perfect day is six hours of family time, two hours spent with friends, 1.5 hour socialising, two hours exercising and one hour eating and drinking. Additionally, the perfect day should involve no more than six hours of work and less than 15 minutes commuting.

Bennett's tree kangaroos, one of Australia's most mysterious marsupials, have long eluded researchers. Our new study, published in Australian Mammalogy today, has achieved a breakthrough: using thermal drones to detect these rare animals with unprecedented efficiency. Tree kangaroos are found only in the tropical rainforests of Australia and New Guinea. Unlike their ground-dwelling relatives, they spend their lives in treetops, feeding on leaves and vines. Their dependence on rainforest trees makes them vulnerable to deforestation and climate change.

Whether it's taking on more responsibilities or staying late in the office, many employees will go above and beyond to try to get a pay rise. But now a study suggests that if you're not good looking, your efforts may be futile. Researchers from the Institute for Operations Research and the Management Sciences in Baltimore have uncovered a'striking' link between physical attractiveness and career success. In their study, the team analysed the careers of more than 40,000 graduates who had completed MBAs. They found attractive respondents earned up to 11 per cent more than their colleagues who were seen as less good looking.
