    The most ambitious project ever conceived on the Internet: Google's master plan to scan every book in the world and the people trying to stop them. Google says they are building a library for mankind, but some say they also have other intentions.

Lab Culture: Glowing Fish Brains, Cartoons, and Espresso in the Florian Engert Lab - Ph... - 0 views

  •  
    "I visit a lot of molecular biology labs, and most of them look pretty much identical: lab benches, microscopes, computers, messy break rooms, big filing cabinets crammed into every free corner. When you look closely, though, every lab has its own flavor, its own culture. This is the first post of what I hope will be a fun, photo-heavy series on the culture of different labs. Florian Engert's lab at Harvard is large, colorful, and messy."

    "We have sensitive body parts wired to the same area of the brain as rodents' fine-tuned whiskers. In people, "stimulating the fingers, lips or face in general could all have a similar effect," says UCI doctoral student Melissa Davis, co-author of the study, which appears in the June issue of PLoS ONE. "It's gender-neutral," adds co-author Ron Frostig, professor of neurobiology & behavior. He cautions that the research, funded by the National Institutes of Health, is a first step, albeit an important one.... "with the potential for maybe doing things before a victim even reaches the emergency room.""

Tung, Barreiro, Johnson, Gilad Social stress affects immune system gene expression in m... - 0 views

  •  
    "Previous research on rhesus macaques discovered that social rank influenced components of the stress response, brain, and immune system. With gene chip technology for measuring the expression of over 6,000 different genes, Tung, Gilad and colleagues at Yerkes, Emory University, and Johns Hopkins looked for the first time in primates at the effects of social rank on genetic function. Comparing 49 different female monkeys of different rank revealed significant changes in the expression of 987 genes, including 112 genes associated with immune system function. The result fits with data in monkeys where low rank and chronic stress lead to compromised immune function, and, more loosely, with human studies linking low socioeconomic status and high social stress to elevated disease risk."

H. Takahashi et al. Think that's not fair? Your serotonin must be high. | The Scicuriou... - 0 views

    "What they found here was a negative correlation. The MORE serotonin transporters you had, the less likely you were to reject unfair offers. The authors interpret this to mean that people with lower levels of serotonin transporter had a harsher sense of "fairness", than those with higher levels of serotonin transporter, and were more inclined to reject unfair offers. Why could this be the case? The authors looked at the personalities of the individuals. You might think that people with more aggressive personalities (or at least a tendency to get offended) might be more likely to reject unfair offers, but it turned out that this wasn't the case. Instead, it was people with more peaceful personalities, but stronger measures of trust, were more likely to reject the unfair offers. The authors believe that the people with higher trustfulness had higher standards of behavior, and thus were more likely to reject unfair offers, even if the rejected ended up badly for them"

Why Interacting with a Woman Can Leave Men "Cognitively Impaired": Scientific American - 0 views

  •  
    "It seems like his brain isn't working quite properly and according to new findings, it may not be. Researchers have begun to explore the cognitive impairment that men experience before and after interacting with women. A 2009 study demonstrated that after a short interaction with an attractive woman, men experienced a decline in mental performance. A more recent study suggests that this cognitive impairment takes hold even w hen men simply anticipate interacting with a woman who they know very little about. Sanne Nauts ... Daisy Grewal is a researcher at the Stanford School of Medicine, where she investigates how stereotypes affect the careers of women and minority scientists."

J. Lee, Vincent Harley: The male fight-flight response: MAO-A, A result of SRY regulati... - 0 views

  •  
    "Males and females differ in their biobehavioural response to stress, where males exhibit a heightened sympathetic response to stress compared with females. Specifically, Taylor et al. 1 propose that the classic "fight-or-flight" response to stress is adaptive for males, whilst females engage in a so-called "tend-and-befriend" response to stress. We propose that the Y-chromosome gene, SRY (sex-determining region on the Y chromosome), provides a genetic basis for the heightened sympathetic reactivity to stress and thus predominance of "fight-flight" response in males. Our idea is based on studies that demonstrate (i) the presence of SRY in brain regions and peripheral tissues abundant in catecholamines, (ii) the regulation of catecholamine synthesis and breakdown by SRY, and (iii) the role of SRY in voluntary movement and blood pressure in males"

    While a substantial body of work has been devoted to understanding the role of negative stereotypes in racial attitudes, far less is known about how we deal with contradictions of those stereotypes. This article uses functional brain imaging with contextually rich visual stimuli to explore the neural mechanisms that are involved in cognition about social norms and race. We present evidence that racial stereotypes are more about the stereotypes than about race per se. Amygdala activity (correlated with negative racial attitudes in other studies) appeared driven by norm violation, rather than race.

    "It is a widely accepted principle of distributive justice that goods should be distributed to individuals according to their contribution, i.e., people should receive equal pay for equal work (equity principle)...Recently, neuroscientific studies have begun to address neural processes underlying social and economic phenomena like e.g., reactions to norm violations, status concerns, and reactions to unfair behavior. These studies have convergingly identified brain regions that are important for these aspects of social behavior. One consistent finding is that activations of the dopaminergic mesolimbic ("reward") system, especially the nucleus accumbens (NAcc) do not exclusively reflect material self-interest, but also social aspects

MPG, Michael Czisch: The Seat of Meta-Consciousness in the Brain | Neuroscience News - 0 views

  •  
    "During wakefulness, we are always conscious of ourselves. In sleep, however, we are not. But there are people, known as lucid dreamers, who can become aware of dreaming during sleep. Studies employing magnetic resonance tomography (MRT) have now been able to demonstrate that a specific cortical network consisting of the right dorsolateral prefrontal cortex, the frontopolar regions and the precuneus is activated when this lucid consciousness is attained. All of these regions are associated with self-reflective functions. This research into lucid dreaming gives the authors of the latest study insight into the neural basis of human consciousness."

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"

The Biology of Consciousness | WBUR and NPR - On Point with Tom Ashbrook - 0 views

  •  
    "Renegade husband and wife philosophers Pat and Paul Churchland met forty years ago in a college Plato class. Their instincts as philosophers - then and now - run outside the philosophy mainstream. Where most philosophers looked to reason and logic to apprehend the human mind, the Churchlands looked - and look - to science. There is no independent "mind", these two practically say, just the human brain, three pounds of tissue and water, firing away behind all our emotions, beliefs, actions. Consciousness itself, they say, is straight biology, a machine. Once, that sounded esoteric. Now, it's on the frontline of debate over law, soul and life."
