SkyandTelescope.com - News from Sky & Telescope - A Tropical Tempest on Titan - 0 views

  •  
    There's an old saying that describes the weather in Maine as "9 months of wintah, and 3 months of damn poor sleddin'." But even the hardiest Mainer would be challenged by the climate on Saturn's big moon Titan, where "wintah" lasts 7½ years, temperatures struggle to reach -290°F (-178°C), the ground is rock-hard water ice, and a mix of liquid methane and ethane rains from the sky.

From butterfly to caterpillar: How children grow up - New Scientist - 0 views

  •  
    In the past 30 years, a scientific revolution has completely transformed our understanding of babies and young children. Babies both know more and learn more than we would ever have thought possible, and we have recently begun to grasp the mechanisms by which they do this. I wrote The Philosophical Baby to try to show that thinking about childhood can help us answer deep questions about truth, imagination, love, consciousness, identity and morality. Without exaggeration, I believe it can tell us how we came to be human.

Physicist Proposes Solution to Arrow-of-Time Paradox - 0 views

  •  
    Entropy can decrease, according to a new proposal - but the process would destroy any evidence of its existence, and erase any memory an observer might have of it. It sounds like the plot to a weird sci-fi movie, but the idea has recently been suggested by theoretical physicist Lorenzo Maccone, currently a visiting scientist at MIT, in an attempt to solve a longstanding paradox in physics.

Birth Control for Stars -- ScienceNOW - 0 views

  •  
    New findings show that the giant clouds of dust and gas that pervade the universe, out of which form all of the stars and other assorted celestial bodies, depend on magnetism to regulate their collapse. If confirmed, the study would resolve a long-standing mystery about the star-forming process.

Giant Snake Ate Baby Dinosaurs | LiveScience - 0 views

  • The site that yielded the snake — dubbed Sanajeh indicus, or "ancient-gaped one from India" — was located near a village in Gujarat in western India. It was a rich nesting ground for sauropods known as titanosaurs, with evidence for hundreds of egg clutches, each containing about six to 12 round, spherical eggs. Two other instances of fossil snakes found with these clutches suggest the newly described serpent species made its living plundering nests for young dinosaurs. "It would have been a smorgasbord," said researcher Jason Head, a paleontologist at the University of Toronto at Mississauga. "Hundreds or thousands of defenseless baby sauropods could have supported an ecosystem of predators during the hatching season." The dinosaur eggs likely were laid along the sandy banks of a small, quiet tributary and covered afterward by the mother with a thin layer of sediment. These dinosaurs did not seem to look after their young — no evidence for adults has been found at the site. The fact the bones and delicate structures, such as eggshells and the snake's skull, are arranged in anatomical order (as they would appear in real life) points to quick entombment of a serpent caught in the act, as opposed to them all getting washed together after they died. "Burial was rapid and deep," said researcher Shanan Peters, a geologist at the University of Wisconsin. "Probably a pulse of slushy sand and mud released during a storm."

    The last thing hatchling dinosaurs might have seen were giant snakes, researchers say. Scientists found the nearly complete remains of an 11-foot-long, 67-million-year-old serpent coiled around a crushed dinosaur egg right next to a hatchling in the nest of a sauropod dinosaur, the largest animals to have ever walked the Earth. "We think that the hatchling had just exited its egg, and that activity attracted the snake," explained researcher Dhananjay Mohabey, a paleontologist at the Geological Survey of India. "It was such a thrill to discover such a portentous moment frozen in time."

    It sounds like something a guided missile would do. Foxes seem to zero in on prey using Earth's magnetic field. They are the first animal thought to use the field to judge distance rather than just direction.

First 'living' laser made from kidney cell - physics-math - 12 June 2011 - New Scientist - 0 views

  •  
    It's not quite Cyclops, the sci-fi superhero from the X-Men franchise whose eyes produce destructive blasts of light, but for the first time a laser has been created using a biological cell. The human kidney cell that was used to make the laser survived the experience. In future such "living lasers" might be created inside live animals, which could potentially allow internal tissues to be imaged in unprecedented detail. It's not the first unconventional laser. Other attempts include lasers made of Jell-O and powered by nuclear reactors (see box below). But how do you go about giving a living cell this bizarre ability? Typically, a laser consists of two mirrors on either side of a gain medium - a material whose structural properties allow it to amplify light. A source of energy such as a flash tube or electrical discharge excites the atoms in the gain medium, releasing photons. Normally, these would shoot out in random directions, as in the broad beam of a flashlight, but a laser uses mirrors on either end of the gain medium to create a directed beam. As photons bounce back and forth between the mirrors, repeatedly passing through the gain medium, they stimulate other atoms to release photons of exactly the same wavelength, phase and direction. Eventually, a concentrated single-frequency beam of light erupts through one of the mirrors as laser light.

Does that hurt? Objective way to measure pain being developed - 0 views

  •  
    ScienceDaily (Sep. 14, 2011) - Researchers from the Stanford University School of Medicine have taken a first step toward developing a diagnostic tool that could eliminate a major hurdle in pain medicine -- the dependency on self-reporting to measure the presence or absence of pain. The new tool would use patterns of brain activity to give an objective physiologic assessment of whether someone is in pain.

How Culture Shapes Our Mind and Brain | Brain Blogger - 0 views

  •  
    Most people would agree that culture can have a large effect on our daily lives - influencing what we may wear, say, or find humorous. But many people may be surprised to learn that culture may even effect how our brain responds to different stimuli. Indeed, until recently, most psychology and neuroscience researchers took for granted that their findings translated across individuals in various cultures. In the past decade, however, research has begun to unravel how cultural belief systems shape our thoughts and behaviors.

Quantum magic trick shows reality is what you make it - physics-math - 22 June 2011 - N... - 2 views

  •  
    In 1967, Simon Kochen and Ernst Specker proved mathematically that even for a single quantum object, where entanglement is not possible, the values that you obtain when you measure its properties depend on the context. So the value of property A, say, depends on whether you chose to measure it with property B, or with property C. In other words, there is no reality independent of the choice of measurement. It wasn't until 2008, however, that Alexander Klyachko of Bilkent University in Ankara, Turkey, and colleagues devised a feasible test for this prediction. They calculated that if you repeatedly measured five different pairs of properties of a quantum particle that was in a superposition of three states, the results would differ for the quantum system compared with a classical system with hidden variables. That's because quantum properties are not fixed, but vary depending on the choice of measurements, which skews the statistics. "This was a very clever idea," says Anton Zeilinger of the Institute for Quantum Optics, Quantum Nanophysics and Quantum Information in Vienna, Austria. "The question was how to realise this in an experiment." Now he, Radek Lapkiewicz and colleagues have realised the idea experimentally. They used photons, each in a superposition in which they simultaneously took three paths. Then they repeated a sequence of five pairs of measurements on various properties of the photons, such as their polarisations, tens of thousands of times. A beautiful experiment They found that the resulting statistics could only be explained if the combination of properties that was tested was affecting the value of the property being measured. "There is no sense in assuming that what we do not measure about a system has [an independent] reality," Zeilinger concludes.

Top 10 Data Integration and Management Challenges in the Pharma Value Chain | ACL Digital - 0 views

  •  
    Medicines and healthcare are synonymous globally. As treatments become more innovative, to address unmet clinical needs, it is important that there is innovation in the pharma value chain as well. In order that patients receive the right medicine, at the right time and the right place, there is a need for a complex value chain. The full set of activities that occur prior to a patient receiving a medicine, constitute the pharmaceutical value chain. This value would differ within markets and also between markets. https://www.acldigital.com/blogs/top-10-data-integration-and-management-challenges-pharma-value-chain

Over 50? You probably prefer negative stories about young people - 0 views

  •  
    "ScienceDaily (Aug. 30, 2010) - When given a choice, older people prefer to read negative news, rather than positive news, about young adults, a new study suggests. In fact, older readers who chose to read negative stories about young individuals actually get a small boost in their self-esteem, according to the results."
  •  
    How many adults were tested and where? This would validate what I have heard, that adults are children in large bodies. This means that many or most adults never mature emotionally? Of course you'll have to exclude me and others I'm sure out there, because negative news whether about young or old depresses me.

Ray Kurzweil Speaks! The Singularity Explained - 0 views

  •  
    I wish everyone would watch this presentation by Ray at the Killer App Expo in Fort Wayne, Indiana. There's a natural skepticism people feel when they first hear or read about the predictions made by Ray's Law of Accelerating Returns, but when you listen to him explain how it has worked and will work, you can't help but take him seriously.

...You Might Be Wearing Nanotech - 0 views

  •  
    When it comes to nanotechnology, we've already pointed out that the public is blissfully unaware. I'm not sure why advertisers aren't making more of a fuss about it; perhaps they're wary of a negative reaction from consumers who may be a bit frightened by it. It's possible that people who would accept it, even welcome it, don't have as much money as the fraidy cats. But this is all speculation.
