Politics and eye movement: Liberals focus their attention on 'gaze cues' much different... - 0 views

  •  
    In a new study, researchers measured both liberals' and conservatives' reaction to "gaze cues" -- a person's tendency to shift attention in a direction consistent with another person's eye movements. Liberals responded strongly to the prompts, consistently moving their attention in the direction suggested to them by a face on a computer screen. Conservatives, on the other hand, did not

Seeing the world with new eyes: Biosynthetic corneas restore vision in humans - 1 views

  •  
    "ScienceDaily (Aug. 25, 2010) - A new study from researchers in Canada and Sweden has shown that biosynthetic corneas can help regenerate and repair damaged eye tissue and improve vision in humans. The results, from an early phase clinical trial with 10 patients, are published in the August 25th, 2010 issue of Science Translational Medicine"

You can believe your eyes: New insights into memory without conscious awareness - 0 views

  •  
    Scientists may have discovered a way to glean information about stored memories by tracking patterns of eye movements, even when an individual is unable (or perhaps even unwilling) to report what they remember.

SETILive - 0 views

  •  
    SETILive is taking the Search for Extraterrestrial Intelligence (SETI) directly to you by presenting radio frequency signals LIVE from the SETI Institute's Allen Telescope Array (ATA) while it's pointed at stars that, based on Kepler exoplanet discoveries, have the best chances of being home to an alien civilization. We'll also be putting you "in the loop" where if enough of you see a potential extraterrestrial (ET) signal in the same data, then within minutes, the ATA will be interrupted and sent back to take a second look. The data you see will be from frequencies where human-made Radio Frequency Interference (RFI) crowds them and we believe the human eye will have a better chance than SETI's computer algorithms to find ET signals there.

Trafton Drew: Why Even Radiologists Can Miss A Gorilla Hiding In Plain Sight - 0 views

  •  
    "He then asked a bunch of radiologists to review the slides of lungs for cancerous nodules. He wanted to see if they would notice a gorilla the size of a matchbook glaring angrily at them from inside the slide. But they didn't: 83 percent of the radiologists missed it, Drew says. This wasn't because the eyes of the radiologists didn't happen to fall on the large, angry gorilla. Instead, the problem was in the way their brains had framed what they were doing. They were looking for cancer nodules, not gorillas. "They look right at it, but because they're not looking for a gorilla, they don't see that it's a gorilla," Drew says. In other words, what we're thinking about - what we're focused on - filters the world around us so aggressively that it literally shapes what we see"

Justin Hudnall: I really do believe that repression makes you sick. - 0 views

    "Hudnall: I really do believe that repression makes you sick. I'm big believer of what is coming out in the neuroscience and therapy community. Brene Brown, who is a shame and guilt expert, said it best: "We have an epidemic of shame in this country." If you keep things inside and have no one to talk to - and this is not crystals and patchouli - you will get sick, you will be miserable, you will ruin your relationships, and you will be unhappy. I know people whose lives were ruined by silence. Especially women. The one thing that has really opened my eyes while teaching is just what we do to our women. Only my women students have said to me, "I don't know if I have anything worth saying." It smacks me in the face every day. We are really fucking up our women"

Remembering Without Knowing It -- ScienceNOW - 0 views

  •  
    Have a friend remove an object from a room you know well--say, a napkin holder from your kitchen--and then see if you can guess what he's taken away. Even if you don't know the answer, your eyes will unconsciously fixate on the stretch of countertop next to the toaster where the holder usually sits. Remembering what goes where in your kitchen is called relational memory, and now scientists have shown that your unknowing stare may be a sign that your brain remembers even when you don't.

Darkness increases dishonest behavior - 0 views

  •  
    "Darkness can conceal identity and encourage moral transgressions; thus Ralph Waldo Emerson wrote in "Worship" in The Conduct of Life (1860), "as gaslight is the best nocturnal police, so the universe protects itself by pitiless publicity." New research in Psychological Science, a journal of the Association for Psychological Science, shows that darkness may also induce a psychological feeling of illusory anonymity, just as children playing "hide and seek" will close their eyes and believe that other cannot see them, the experience of darkness, even one as subtle as wearing a pair of sunglasses, triggers the belief that we are warded from others' attention and inspections."

Everything We Knew About Human Vision is Wrong: Author Mark Changizi Tells Us... - 0 views

  • Our funny primate variety of color vision turns out to be optimized for seeing the physiological modulations in the blood in the skin that underlies our primate color signals.
  •  
    For theoretical neurobiologist and author Mark Changizi, "why" has always been more interesting than "how." While many scientists focus on the mechanics of how we do what we do, his research aims to grasp the ultimate foundations underlying why we think, feel and see as we do. Guided by this philosophy, he has made important discoveries on why we see in color, why we see illusions, why we have forward-facing eyes, why letters are shaped as they are, why the brain is organized as it is, why animals have as many limbs and fingers as they do, and why the dictionary is organized as it is.

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.

    A new project to create a 3D map of space so large that scientists can find a 500 million-light-year-size remnant from the early universe inside it began operation last month. The Baryon Oscillation Spectroscopic Survey opened its eyes to the universe, taking in data from hundreds of galaxies and quasars in the constellation Aquarius, from its perch on the Apache Point Observatory in New Mexico. Eventually, it will image two million galaxies and quasars.

Why Sleepyheads Forget -- ScienceNOW - 0 views

  •  
    Red-eye flights, all-night study sessions, and extra-inning playoff games all deprive us of sleep and can leave us forgetful the next day. Now scientists have discovered that lost sleep disrupts a specific molecule in the brain's memory circuitry, possibly leading to treatments for tired brains.

Why animals don't have infrared vision: Source of the visual system's 'false alarms' di... - 2 views

  •  
    ScienceDaily (June 9, 2011) - On rare occasion, the light-sensing photoreceptor cells in the eye misfire and signal to the brain as if they have captured photons, when in reality they haven't. For years this phenomenon remained a mystery. Reporting in the June 10 issue of Science, neuroscientists at the Johns Hopkins University School of Medicine have discovered that a light-capturing pigment molecule in photoreceptors can be triggered by heat, as well, giving rise to these false alarms.

What Do Nanomachines Look Like? - 0 views

  •  
    When you hear about nanotechnology (and you will hear about it more and more since it's moving into the mainstream of manufacturing), you might wonder what a nanomachine might look like. Since you can't see them with your unaided eye, you have to look at highly magnified images. But for the folks whose job it is to design the tiny parts for the nanomachines, some powerful design software comes into play.
