Your Pet Is Actually A Sneaky Master Of Doggie Deception

Your Pet Is Actually A Sneaky Master Of Doggie Deception

Science
Who’s a good boy? Your dog is, right? Your dog is the best dog in the world. Or is he? Maybe that's what he wants you to think. A new study has shown that dogs are actually deceptively sneaky and manipulative in getting what they want, whether that is a doggy treat, a tummy rub, or – according to this particular study – a sausage, by actively deploying “tactical deception”. The study, published in Animal Cognition, was carried out by Marianne Heberlein, who studies dog cognition at the University of Zurich, Switzerland. She was inspired to carry out the study after spying one of her own dogs pretending to gaze at something interesting in the yard, tricking her other dog into giving up his sleeping spot. “This sort of thing happens quite often, but it is not well studied,” she told
Two Scientists Contemplate If Aliens Are Behind Fast Radio Bursts

Two Scientists Contemplate If Aliens Are Behind Fast Radio Bursts

Science
When facing a new and unknown astronomical phenomenon astronomers have two options: Put the word "dark" in front of it or state that it could be aliens. Fast radio bursts (FRBs) – incredibly powerful and brief sources of radio waves of unknown extragalactic origin – have attracted more and more of the latter. The latest in this list comes from Harvard physicists Avi Loeb and Manasvi Lingam, who have produced a new study, accepted for publication in the Astrophysical Journal Letters, on what a potential artificial source of FRBs would look like. "Fast radio bursts are exceedingly bright given their short duration and origin at great distances, and we haven't identified a possible natural source with any confidence," Loeb said in a statement. "An artificial origin is worth contemplatin

One Delicious Combination Will Boost Attention Better Than Any Other Drink, Says Study

Science
In the world’s best argument to badger your boss for a coffee machine in the office, scientists have discovered a mocha is the best thing to boost your attention span. Yes, that delicious combination of coffee and cocoa is the perfect marriage for motivation, so says science. Researchers from Clarkson University and the University of Georgia studied the effects of caffeinated and non-caffeinated brewed cocoa on attention span, motivation to perform cognitive work, and feelings of anxiety, energy, and fatigue. Their results, published in BMC Nutrition, showed the combination of fatigue-fighting coffee and anxiety-reducing cocoa was the best combination for boosting attention span.  "It was a really fun study," said lead author Ali Boolani of Clarkson University in a statement. "Cocoa in
In an Unexplained Case, Brain Activity Has Been Recorded as Much as 10 Minutes After Death

In an Unexplained Case, Brain Activity Has Been Recorded as Much as 10 Minutes After Death

Science
Doctors in a Canadian intensive care unit have stumbled on a very strange case - when life support was turned off for four terminal patients, one of them showed persistent brain activity even after they were declared clinically dead. For more than 10 minutes after doctors confirmed death through a range of observations, including the absence of a pulse and unreactive pupils, the patient appeared to experience the same kind of brain waves (delta wave bursts) we get during deep sleep. And it's an entirely different phenomenon to the sudden 'death wave' that's been observed in rats following decapitation. "In one patient, single delta wave bursts persisted following the cessation of both the cardiac rhythm and arterial blood pressure (ABP)," the team from the University of Western Ontar...
Scientists Have Stored a Movie, a Computer OS, and an Amazon Gift Card in a Single Speck of DNA


Scientists Have Stored a Movie, a Computer OS, and an Amazon Gift Card in a Single Speck of DNA


Science
Scientists have developed what they claim is the most efficient data storage technique ever, with a new DNA-encoding method that approaches the theoretical maximum for information stored per nucleotide. Using an algorithm called DNA Fountain, the researchers squeezed six files into a single speck of DNA – including a short film, an entire computer OS, and an Amazon gift card – but that's just for starters. The team says the same technique could effectively compress all the world's data into a single room. Not only is DNA data storage an amazing space saver; the technique could also enable us to preserve knowledge with extreme robustness and longevity – unlike traditional technology media, which is known to succumb to all kinds of faults with time. "DNA won't degrade over time like

‘Physics-Defying’ Gravity Hills Are One of the Strangest Natural Phenomena We’ve Seen

Science
Scattered across the world are a number of bewildering 'mystery spots' that appear to defy gravity - places where cars seem to drift uphill, and cyclists struggle to push themselves downhill. Also known as gravity hills, these bizarre natural phenomena can be found in places like Confusion Hill in California and Magnetic Hill in Canada, and while they've inspired rumours of witchcraft and giant magnets buried in the countryside, the actual scientific explanation will have you questioning every slope you encounter from here on out. There are reportedly dozens of gravity hills around the world, in the US, the UK, Australia, Brazil, and Italy, and they all have one thing in common - if you drive your car to the bottom of the hill and put it in neutral, it will proceed to roll back UP th

Time Crystals: How Scientists Created A New State Of Matter

Science
Some of the most profound predictions in theoretical physics, such as Einstein’s gravitational waves or Higgs’ boson, have taken decades to prove with experiments. But every now and then, a prediction can become established fact in an astonishingly short time. This is what happened with “time crystals”, a new and strange state of matter that was the orised, disproved, revamped and finally created in just five years since it was first predicted in 2012.  Crystals, such as diamond and quartz, are made of atoms arranged in a repeating pattern in space. In these new crystals, atoms also follow a repeating pattern, but in time. Because of this weird property, time crystals could one day find applications in revolutionary technologies such as quantum computing. The story of time crystals begin

Would you take a painkiller that had been developed from human saliva? A recent study suggests you might in future.Pain is an essential sensation. Sensory nerves with endings in our skin, tissues and organs, are activated by heat, cold or pressure, or by chemicals that are released from cells after tissue injury. The fibres of these nerves reach the central nervous system, activating neurons in the spinal cord which in turn connect with and activate neurons in a part of the brain known as the cerebral cortex. The cortex gives you the conscious perception of pain - that "ouch!" The system has evolved to produce a quick response. It takes a split second for you to withdraw your hand from a burning flame. While pain is essential for survival and good health, unless you have masoch

Humanity’s Actions Have Given Rise To 208 New Mineral Types

Humans really are unique in both good and bad ways. The mixture of our curiosity, intelligence, impatience, and fallibility means that we have now entered the Anthropocene, Earth’s newest geological epoch that began the moment plutonium debris from nuclear weapons began blanketing the globe. This atomic marker is just one of many. Lest we forget that we have the power to physically change the make-up of the planet itself – whether we mean to or not. It’s long been known that new geological formations – mixtures of plastic and natural rock – are appearing as a result of human activity, but a new review highlights that we’ve also crafted hundreds of man-made minerals too. As reported by the journal American Mineralogist, scientists have agreed that, from ancient crafting to modern mini
Physicists Say They’ve Created an ‘Impossible’ New Form of Matter: Supersolids

Physicists Say They’ve Created an ‘Impossible’ New Form of Matter: Supersolids

Science
Our world just got a little stranger, with physicists claiming they've successfully created a brand new 'impossible' form of matter in the lab - supersolids, which have properties of both liquids and solids at the same time. Scientists have predicted that this exotic state of matter could exist for more than 50 years, but no one had been able to demonstrate that it's actually possible. Now, two independent teams of physicists have used different techniques to achieve the same odd result - what they claim are the first examples of supersolid matter. There's sure to be controversy over whether these new experiments unequivocally demonstrate a supersolid state - especially after a similar claim in 2004 went on to be debunked -  but this is the most compelling evidence yet that super
