China vs United States As we discussed in yesterday’s post, whether the United States and China like it or not, the economic futures of both countries are intertwined. Everyone knows that China’s got more people and that its importance as an economic superpower has escalated in recent years. What you might not understand is how the differences between our countries, in economic philosophy, in population, in geography and in how the military is built and paid for ultimately play into the entire economic relationship. An On-Off Switch for Anxiety With the flick of a precisely placed light switch, mice can be induced to cower in a corner in fear or bravely explore their environment. The study highlights the power of optogenetics technology—which allows neuroscientists to control genetically engineered neurons with light—to explore the functions of complex neural wiring and to control behavior. In the study, Karl Deisseroth and collaborators at Stanford University identified a specific circuit in the amygdala, a part of the brain that is central to fear, aggression, and other basic emotions, that appears to regulate anxiety in rodents.

Review of Galantamine: the Lucid Dreaming Pill So you’re considering the red pill… Galantamine has emerged as THE lucid dreaming pill.

Knight's tour An open knight's tour of a chessboard An animation of a knight's tour on a 5 by 5 board. A knight's tour is a sequence of moves of a knight on a chessboard such that the knight visits every square only once. If the knight ends on a square that is one knight's move from the beginning square (so that it could tour the board again immediately, following the same path), the tour is closed, otherwise it is open. The exact number of open tours on an 8x8 chessboard is still unknown.

Is College Really Worth It? Is going to college really worth it? Probably so, but it's not that clear cut, and economics have been arguing the point for 30 years. Most studies tend to show that college-educated people end up making far more money in the course of their lifetimes. (The niggle: Usually, it's not worth paying for a private university.) Still, that evidence isn't totally cut and dry: What do you really learn in college? Is what you learned in college really what's producing the value? Mind vs. Machine - Magazine In the race to build computers that can think like humans, the proving ground is the Turing Test—an annual battle between the world’s most advanced artificial-intelligence programs and ordinary people. The objective? To find out whether a computer can act “more human” than a person. In his own quest to beat the machines, the author discovers that the march of technology isn’t just changing how we live, it’s raising new questions about what it means to be human. Bryan Christie

Lucid Dreaming/Using Dream stabilization[edit] Once you are able to dream lucidly, you may find that it is difficult to stay in the dream; for example, you may wake instantly or the dream may start “fading” which is characterized by loss or degradation of any of the senses, especially vision. Alternatively, a new lucid dreamer could easily forget that they are in a dream, as a result of the shock of the sensation. Don't worry if you wake immediately after becoming lucid. As you gain more experience of becoming lucid, it will come as less of a shock and you’ll be less likely to wake up. Make sure you do a reality check to be sure you’re not still dreaming.

True Colors Infographic - Breakdown of Color Preferences by Gender From the day that babies are brought home and cradled in their pink or blue blankets, implications have been made about gender and color. While there are no concrete rules about what colors are exclusively feminine or masculine, there have been studies conducted over the past seven decades that draw some generalizations. Let’s take a look at what they say about color and gender.
