  • How Science Found a Way to Help Coma Patients Communicate

    How Science Found a Way to Help Coma Patients Communicate

    via Guardian : In 20 December 1999, a young man pulled away in his car from his grandfather’s house in Sarnia, Ontario, with his girlfriend in the passenger seat beside him. Scott Routley, who was 26, had studied physics at the University of Waterloo and had a promising career in robotics ahead of him. But at an intersection just a few blocks from his grandfather’s house, a police car travelling to the scene of a crime […]

  • Why Midsized Animals Are the Fastest on Earth

    Why Midsized Animals Are the Fastest on Earth

    via Science : An elephant should run faster than a horse—at least in theory. That’s because big creatures have more of the type of muscle cells used for acceleration. Yet midsized animals are the fastest on Earth, a trend that researchers have long struggled to explain. Now, an analysis of nearly 500 species ranging from fruit flies to whales has an answer: The muscle cells in big animals run out of fuel before the creatures can […]

  • Feeling ‘hangry’ is a very real thing – science says so

    Feeling ‘hangry’ is a very real thing – science says so

    Via Metro : We’ve all been there – with hours to go between mealtimes, that furious rage bubbles up. You’re feeling ‘hangry’: that’s when hungry meets angry, for those of you at the back. Long thought of as a highly relatable old wives’ tale, that feeling of ‘hanger’ has now been proven to have some scientific basis. According to New Scientist, there is a link between blood sugar levels and the hormones that trigger aggression and […]

  • How Plants Grow Like Human Brains

    How Plants Grow Like Human Brains

    via ScienceDaily : Plants and brains are more alike than you might think: Salk scientists discovered that the mathematical rules governing how plants grow are similar to how brain cells sprout connections. The new work, published in Current Biology on July 6, 2017, and based on data from 3D laser scanning of plants, suggests there may be universal rules of logic governing branching growth across many biological systems. “Our project was motivated by the question of […]

  • How Giant Atoms May Help Catch Gravitational Waves from the Big Bang

    How Giant Atoms May Help Catch Gravitational Waves from the Big Bang

    via COSMOS : There was a lot of excitement last year when the LIGO collaboration detected gravitational waves, which are ripples in the fabric of space itself. And it’s no wonder – it was one of the most important discoveries of the century. By measuring gravitational waves from intense astrophysical processes like merging black holes, the experiment opens up a completely new way of observing and understanding the universe. But there are limits to what LIGO […]

  • Why Fake News Goes Viral: Science Explains

    Why Fake News Goes Viral: Science Explains

    Via LiveScience : People’s limited attention spans, plus the sheer overload of information on social media may combine to make fake news and hoaxes go viral, according to a new study. Understanding why and how fake news spreads may one day help researchers develop tools to combat its spread, the researchers said. For example, the new research points toward curbing the use of social bots — computer programs that automatically generate messages such as tweets that […]

  • Astronomers measure the mass of a star—thanks to an old tip from Einstein

    Astronomers measure the mass of a star—thanks to an old tip from Einstein

    Via Science : Weighing a star is hard. In fact, binary stars are the only ones scientists can directly gauge, because their orbits around each other reveal their masses. Now, a team of astronomers has succeeded in measuring the mass of an isolated star using a technique first suggested by Albert Einstein in 1936. The method exploits the fact that a large mass, like a star, can bend the path of light. Although the effect is […]

  • China Just Extracted Gas From ‘Flammable Ice’, And It Could Lead to a Brand New Energy Source

    China Just Extracted Gas From ‘Flammable Ice’, And It Could Lead to a Brand New Energy Source

    Via Science Alert : But are we ready for a new fossil fuel? For the first time, Chinese engineers have successfully extracted natural gas from icy deposits beneath the South China Sea. Just last year, China’s government announced that geologists had found new reserves of methane hydrate – also known as ‘flammable ice’ – and now it looks like they’ve managed to harvest some of it, bringing the world a step closer to harnessing this untapped […]

  • Is it really possible to live until you’re 146? The science of ageing

    Is it really possible to live until you’re 146? The science of ageing

    Via The Guardian : Scientists doubt that extreme natural longevity is feasible. But if lifespan is ruled by a genetic ‘clock’, that view could change The grim reaper comes for everyone in the end, but sometimes he is in less of a rush. This was certainly true for Sodimedjo, an Indonesian man who died on Sunday, but whether he was the full 146 years he claimed remains doubtful – not least because his purported birthdate is […]

  • No bones? No problem: DNA left in cave soils can reveal ancient human occupants

    No bones? No problem: DNA left in cave soils can reveal ancient human occupants

    Via Science : Fifty thousand years ago, a Neandertal relieved himself in a cave in present-day Belgium, depositing, among other things, a sample of his DNA. The urine clung to minerals in the soil and the feces eventually decomposed. But traces of the DNA remained, embedded in the cave floor, where earth falling from the cave’s ceiling and blowing in from outside eventually entombed it. Now, researchers have shown they can find and identify such genetic […]
