The Secret Life of a Cat: What mischievous moggies gets up to behind their owners' backs

Under the cover of darkness, Claude slips through the back door of an unknown home and enters the kitchen. As its unsuspecting owners sleep inside, the intruder pads over the terracotta flagstones with barely a sound. He knows what he is looking for and he knows how to get it. He’s done this before. But it isn’t jewellery or electronics that Claude’s after – it’s food. Scroll down for video Lilly the cat at the BBC's feline HQ in Shamley Green, Surrey. Lilly is one of the stars of BBC's Horizon documentary, The Secret Life of the Cat. The makers of the show fitted 50 cats with highly sensitive GPS collars and miniature 'cat cams' that recorded their every move When the cat's away: The BBC Two show followed 50 cats like Thomas, pictured, around the leafy Surrey village of Shamley Green during one week in April Because Claude isn’t just any old burglar. He’s a cat burglar – quite literally. An eight-year-old grey and white tom, he likes chasing mice, sitti

Why living in the mountains affects the way you speak: Thinner air makes it easier to say certain sounds

Where we live - specifically, how high up we live - may have a far bigger impact on how languages are formed than previously thought. Languages containing 'ejective' consonants - guttural bursts of sound not found in English - mainly exist among communities at high altitudes. Lead scientist Dr Caleb Everett from the University of Miami believes that the reason might be that it takes less effort to produce ejectives in thinner mountain air. Scroll down for video On this partial world map, dark circles represent the areas where languages where ejectives occur. Clear circles represent areas where the ejective isn't part of the language. Scientists found a correlation between ejective languages and high altitude. Until recently most linguists believed environment mainly had an influence on vocabulary rather than sound. Researchers in the US found that 87 per cent of the languages with ejectives studied were located within 500 kilometres of a region of high elevation on al

The shorts and sleeping bag that mean you¿ll never run out of mobile battery again (because they're powered by your body heat)

Festival goers need never run out of phone battery again thanks to a new range of denim shorts and sleeping bags that use body heat and movement to generate electricity. The Power Shorts and Recharge Sleeping Bag can charge a phone's battery by harvesting energy from the human body using kinetic and thermoelectric technology. The wearable phone chargers have been designed by mobile phone company Vodafone with help from the University of Southampton.  Vodafone has teamed up with the University of Southampton to create wearable phone chargers for festival goers. The Power Shorts, pictured, capture kinect energy from the wearer's body movements. This energy can then be used to charge mobile handsets This image explains how the Power Shorts work. They are fitted with foam-like ferroelectret smart materials which contain voids. The surfaces of these voids are permanently charged and as the size and shape of the voids in the shorts changes,when they're squashed or def

Britons are the second most prolific Facebook and Twitter users in EUROPE with a fifth now aged over 65

The number of Britons going online has doubled since 2006 and almost half of the 33 million current UK internet users use social networks on a daily basis, new figures show.  People in the UK were also found to be the second most prolific social network users in Europe - being beaten only by the Netherlands - according to figures from the latest report by the Office for National Statistics (ONS) and Eurostat. The figures also discovered that although the majority of UK users are aged between 16 and 24 years old, 19 per cent of people aged 65 to 74 now use social networks. The Office for National Statistics and Eurostat have studied the number of people across Europe who are using social networks. The Netherlands tops the group at 65 per cent with the UK in second place, making up more than half - 57 per cent - of European social network users FACEBOOK AND TWITTER BLAMED FOR CAUSING NARCISSISM The way you use Facebook and Twitter could mirror how narcissistic you are, according to

Ötzi the prehistoric iceman was killed by a blow to the head - and NOT by an arrow, claim scientists

Blood cells extracted from a pin-sized sample of brain tissue may finally prove how Ötzi the iceman mummy met his demise. Since the body was found frozen under the Alps two decades ago, scientists have conducted experiments to learn how he came to be buried between the Austrian and Italian borders more than 5,300 years ago. A hole in his collarbone suggested he was killed by an arrow, then a brain scan concluded he died from a fall. Now, this latest research, from the European Academy of Bolzano/Bozen (EURAC) in Germany, has discovered he suffered brain damage likely caused by a blow to the head. German researchers from the European Academy of Bolzano/Bozen (EURAC) at Saarland and Kiel University extracted protein and blood cells, pictured, from the brain of a 5,-300-year-old mummy. They discovered some of the blood cells were clotted, caused by bruising to the brain The research teams from Saarland and Kiel University used computer-controlled endoscopy to extract two samples of

Prince Harry was right: Playing video games DOES boost brain power and help soldiers prepare for war

Playing video games really may have helped Prince Harry spot the enemy faster, research suggests. Researchers say that video game consoles help the brain to make better and faster use of visual input, distinguishing between one object and another - such as a ‘good guy’ and a ‘bad guy’ - more quickly. Prince Harry famously said that he trained for flying Apaches by playing on the computer, and a study by Duke University in America suggests there was some truth in his comment. Prince Harry wearing his monocle gun sight and sitting in his Apache helicopter cockpit in Afghanistan in 2012. He famously said that he trained for flying Apaches by playing on the computer Professor Greg Appelbaum said: 'Gamers see the world differently. They are able to extract more information from a visual scene.' Researchers found 125 participants who were either non-gamers or very intensive gamers then ran them through a visual sensory memory task that flashed a circular arrangement of eight

How fossils of fish that lived 380 million years ago help explain how the modern-day 'six pack' evolved

Breast really is best if you want a brainy baby: Just THREE months of breastfeeding boosts development by 30%

Breast milk boosts brain development in babies by up to 30 per cent, according to a new study. Children exclusively fed breast milk for at least three months have up to 30 per cent extra growth in the key parts of the brain which control language, emotion, and understanding, say scientists. The study of under-fours showed children who have breast milk as part of their diet have a clear advantage when it comes to brain development. Children exclusively fed breast milk for at least three months have up to 30 per cent extra growth in the key parts of the brain. Image shows how white matter develops with age Research carried out at Brown University, in the U.S., found that by the time the babies had reached their second birthday a discernible difference could be seen in their brain structure. Dr Sean Deoni, an engineering professor and lead author, said: ‘We're finding the difference [in white matter growth] is in the order of 20 to 30 per cent, comparing the breastfed and the no

Why we eat ice cream when we're sad: Feeling down can reduce our ability to taste fat

From heartache to hangovers, it's the emotional crutch that many a woman will turn to. But why is it so hard to stop after a few scoops of ice cream? A new study suggests that our emotions can make us perceive the taste of food differently - and most significantly, less able to register how much fat we are eating. The researchers, from the University of Wurzburg, in Germany, also found that when people are particularly happy or sad they are better able to detect bitter, sweet and sour flavours. In fact, after watching emotional videos, the study participants’ ability to detect these tastes was increased by 15 per cent. People who are very emotional are less able to detect the fat in food. In the Bridget Jones film, Renee Zellweger is seen tucking into a tub of Ben&Jerry's after breaking up with her boyfriend They asked a group of volunteers to taste a range of creamy drinks containing differing levels of fat. Before taking part in the tasting, they were shown three d

Attention-seeking, naughty, erratic ... Jo thought her son didn't fit in because he was an only child - in fact, he had Asperger's
