Oldest noodles unearthed in China Late Neolithic noodles: They may settle the origin debate The 50cm-long, yellow strands were found in a pot that had probably been buried during a catastrophic flood. Radiocarbon dating of the material taken from the Lajia archaeological site on the Yellow River indicates the food was about 4,000 years old. Scientists tell the journal Nature that the noodles were made using grains from millet grass - unlike modern noodles, which are made with wheat flour. The discovery goes a long way to settling the old argument over who first created the string-like food. Professor Houyuan...

Professor VD Mishra said that new researches have revealed that agricultural practices in India started in Mesolithic period (6-7,000 BC), much before the Neolithic period (4000 BC) as is generally believed. This discovery has proved that agriculture in India started simultaneously with other parts of the world. He said that Sativa rice, discovered from excavations at Chopni in Belan valley, has proved that India did not lag behind in agriculture... Joshi said that encroachments around historical monuments should be stopped because it harms our heritage. Citing an example, he said that Gwalior Fort could not be declared World Heritage due...

What an eggsperiment! A group of high school students in Japan have made an incredible discovery - they've figured out how to hatch a perfectly healthy chick from an egg without the shell. The discovery is so significant, the students' findings have been published in a scientific journal. The experiment - which was filmed and then shared on YouTube - consists of a few very simple steps and takes less than one month. By day three - the little chick's heart had formed, and by day five, the outline of its body could be seen. In just three weeks, a...

They may be man's best friend, but dogs have little to thank humans for it seems. Research suggests the domesticated pets can't solve problems as well as their wild cousins because living with us has made them 'incapable of thinking for themselves.' In tests, experts presented a 'puzzle box' containing food to a group of dogs, and a group of wolves and while the wolves were capable of breaking inside, the dogs looked to humans for help.

Dogs can copy each other's expressions in a split-second just like people, showing signs of basic empathy, according to Italian researchers. Mimicking each other's facial expressions is a human habit, which helps people to get along. Dogs do the same to bond with other dogs, scientists report in the journal, Royal Society Open Science. They think dogs may be showing a basic built-in form of empathy, enabling them to pick up on emotions. And the phenomenon may have emerged in our canine companions during the process of domestication, say scientists from the Natural History Museum, University of Pisa.

This week, millions of people around the world will no doubt experience rapid mimicry-an involuntary, split-second mirroring of another person's facial expressions-as they exchange smiles over gifts, good meals and holiday traditions. This phenomenon, observed in humans and many other primates, is considered a basic building block of our ability to feel empathy. "When your companion or friend smiles, you don't know why exactly, but you immediately react with the same smile to him or her," says Elisabetta Palagi, an evolutionary biologist at the University of Pisa in Italy. "It’s an extremely important phenomenon, because through this mimicry you can...

Dogs really are man's best friend, it seems, as researchers have shown they can recognise emotions in humans by combining information from different senses. They are the only creatures outside of humans who have been observed to have that ability. -SNIP- "Our study shows that dogs have the ability to integrate two different sources of sensory information into a coherent perception of emotion in both humans and dogs. "To do so requires a system of internal categorisation of emotional states. This cognitive ability has until now only been evidenced in primates and the capacity to do this across species only...

A golden jackal (Canis anthus) from Serengeti National Park, Tanzania. Based on genomic results, the researchers suggest this animal be referred to as the African golden wolf, which is distinct from the Eurasian golden jackal (Canis aureus). Credit: D. Gordon E. Robertson ======================================================================================================================= Despite their remarkably similar appearance, the "golden jackals" of East Africa and Eurasia are actually two entirely different species. The discovery, based on DNA evidence and reported in the Cell Press journal Current Biology on July 30, increases the overall biodiversity of the Canidae—the group including dogs, wolves, foxes, and jackals—from 35 living species to 36. "This...

Dogs are becoming more intelligent and are even learning morals from human contact, scientists claim. They say the fact that dogs' play rarely escalates into a fight shows the animals abide by social rules. During one study, dogs which held up a paw were rewarded with a food treat. When a lone dog was asked to raise its paw but received no treat, the researchers found it begged for up to 30 minutes. But when they tested two dogs together but rewarded only one, the dog which missed out soon stopped playing the game. Dr Friederike Range, of the University...

The genetic heritage of New Zealand's first dog, the now extinct kuri, is being unravelled by University of Otago scientists using state-of-the-art ancient DNA analysis. University of Otago PhD student Karen Greig has sequenced the complete, or near complete, mitochondrial genomes of 14 kuri represented by bones recovered from Wairau Bar, one on New Zealand's earliest and most important archaeological sites. Kuri were smallish dogs about the size of cocker spaniels and were brought to New Zealand from East Polynesia in the colonising canoes that arrived in the early fourteenth century AD. They were the only domesticated animal to be...

By Paul Rincon 20 October 2015 Dogs may have become man's best friend in Central Asia, according to the study Today's dogs can trace their origins to Central Asia, according to one of the most comprehensive genetic surveys yet. Dogs are the most diverse animal on the planet - a legacy of thousands of years of selective breeding by humans. But they derive from wild wolves that were gradually tamed and inducted into human hunting groups - perhaps near Mongolia or Nepal. The findings come from an analysis of DNA from thousands of pooches, and are published in PNAS journal....

You may think your dog has an irrational hatred of cats, but their instinct to chase felines out of their territory might be more reasonable than you think. Fossils have revealed the two species have a rocky past after the introduction of cats to the Americas had a devastating effect on the continent's species of wild dogs. In fact, it is thought that competition from cats caused up to 40 species of dog to become extinct in the region millions of years ago.

The irresistible gaze of "puppy-dog eyes" has roots in thousands of years of human evolution alongside domesticated dogs, says anthropologist Robert Losey. Anyone who owns a dog is familiar with the "gaze" -- that hypnotic, imploring stare that demands reciprocation. It can seem to hold a world of mystery and longing, or just pure bafflement at what makes humans tick. It turns out that the look of mutual recognition between human and dog reflects thousands of years of evolution, a bond programmed into our very body chemistry. Last spring a research team in Japan discovered that both species release a...

Before humans milked cows, herded goats or raised hogs, before they invented agriculture, or written language, before they had permanent homes, and most certainly before they had cats, they had dogs. Or dogs had them, depending on how you view the human-canine arrangement. But scientists are still debating exactly when and where the ancient bond originated. And a large new study being run out of the University of Oxford here, with collaborators around the world, may soon provide some answers.

The geology of the site, as well as pollen and algae finds, suggest that the hunter-gatherers encountered the mastodon next to a small pond that both humans and animals used as a water source, the researchers believe. Waters said that the prehistoric "people knew how to find game, fresh water and materials for making tools. These people were well adapted to this environment. The site is a slam-dunk pre-Clovis site with unequivocal artifacts, clear stratigraphy and thorough dating." Another research team previously excavated the site and found what they believed were dog remains, so dogs "would most likely have been...

After living alongside humans for thousands of years, it would be nice to think that a bit of our mental agility has rubbed off on dogs. However, it seems that domestic dogs are actually less intellectually capable than the wild relatives they were bred from. Animal psychologists have found that wolves are able to count far better than domestic dogs - and it's because dogs have become used to relying on us to help them.

Man's best friend came about after generations of wolves scavenged alongside humans more than 33,000 years ago in south east Asia, according to new research. Dogs became self-domesticated as they slowly evolved from wolves who joined humans in the hunt, according to the first study of dog genomes. And it shows that the first domesticated dogs came about 33,000 years ago and migrated to Europe, rather than descending from domesticated European wolves 10,000 years ago as had previously been thought.

Humans may have domesticated dogs two separate times, taming wolves both in Europe and Asia thousands of years ago, according to new research. A major international research project may have cleared some of the controversy surrounding the origins of man's best friend, which has until now remained a mystery with two primary hypotheses. The first holds that humans domesticated dogs for the first time in Europe more than 15,000 years ago.
