You should eat salmon before a test, berries to prevent Alzheimer's, or a vitamin supplement to increase your memory. You've heard the term "brain foods" since you were a kid, but how much do you really know about them? More importantly, is there really a way to boost your brain power just be eating a certain type of diet? We talked with two experts to unravel the myths and unpack the facts about how much food can really impact your brain. Just as your stomach, muscles, and heart feed on the nutrients that food supplies, so does the brain.
The body and mind need rest in order to operate at peak performance. When the body and mind do not get the required amounts of rest time, they start doing weird things. Envision for a moment a talking children's toy with dying batteries. The voice slows down and distorts and the moving parts twitch helplessly as they try in vain to move. In some way, this is a good metaphor for sleep deprivation. If you have ever gone longer than twenty four hours without sleep, chances are that you experienced some form of altered state as a result of sleep deprivation.
If you just want to get yourself a pair of perspective flipping goggles, all you have to do is download the file, arrange the parts to be cut (being sure to include two earpieces, they're identical, you know) and laser cut yourself a pair (mirror side down on the plastic, please.) It's pretty simple. What those of you without laser cutters (poor souls that you are) may take away is this cool construction method I learned from puzzle maker Lee Krasnow. I measured my screws, nuts, and washers, and modeled them simply in cad.
(Santa Barbara, Calif.) –– Scientists at UC Santa Barbara have made a major discovery in how the brain encodes memories. The finding, published in the December 24 issue of the journal could eventually lead to the development of new drugs to aid memory. The team of scientists is the first to uncover a central process in encoding memories that occurs at the level of the synapse, where neurons connect with each other. "When we learn new things, when we store memories, there are a number of things that have to happen," said senior author Kenneth S. Kosik, co-director and Harriman Chair in Neuroscience Research, at UCSB's Neuroscience Research Institute. Kosik is a leading researcher in the area of Alzheimer's disease.
By DYLAN EVANS Most of us have to estimate probabilities every day. Whether as a trader betting on the price of a stock, a lawyer gauging a witness's reliability or a doctor pondering the accuracy of a diagnosis, we spend much of our time—consciously or not—guessing about the future based on incomplete information. Unfortunately, decades of research indicate that humans are not very good at this. Most of us, for example, tend to vastly overestimate our chances of winning the lottery, while similarly underestimating the chances that we will get divorced.
March 2008 The web is turning writing into a conversation. Twenty years ago, writers wrote and readers read. The web lets readers respond, and increasingly they do—in comment threads, on forums, and in their own blog posts.
Kevin Cheng ( aka @k ), product manager at Twitter and an all around smart guy wrote a great blog post called Can We Ever Digitally Organize Our Friends? . I've been thinking many of the same things that Kevin wrote about since I started to use Google+ a few weeks ago and Kevin's post is a good opportunity to riff on the same ideas. But first, a bit of humor courtesy of someecards : With that out of the way, here's my thinking on grouping things. I don't like to be that organized personally.

The urge to actively seek out new experiences is a personality trait that psychologists have known about for years, but up until now scientists have been unable to prove how this urge relates to hormonal activities in the brain. Now, an international research team made up of scientists from the University of Copenhagen, University of Aarhus and University of Tokyo have been able to prove for the first time that this hunger for stimulation is greater on average among people who possess more of the gratification hormone - dopamine in the brain. The research team lead by Professor Albert Gjedde from the Department of Neuroscience and Pharmacology at the University of Copenhagen and Doctor Arne Møller from CFIN at Aarhus University used PET scans at Aarhus University Hospital to map the areas in the brain where dopamine was active among healthy volunteers.
We know that the foods we eat affect the body but they can have even more influence on how well our brain functions. What we eat can have a POWERFUL affect on our brain’s energy, how the mind handles tasks, and our general mood. Our focus here is on those particular nutrients found in foods that enhance neuron firing and cross-linking in the brain.

It’s very important to always remember that …Mind control is ubiquitous. It’s almost a question of who is not mind controlled, as opposed to who is mind controlled. It’s just a difference in degree.
WHAT YOU ARE ABOUT TO READ IN THE NEXT PARAGRAPH IS COMMONLY BELIEVED, BUT NOT TRUE – You read by recognizing the shapes of words and groups of words. Words that are in all capital letters all have the same shape: a rectangle of a certain size. This makes words displayed in all uppercase harder to read than upper and lower case (known as “mixed case”). Mixed case words are easier to read because they make unique shapes, as demonstrated by the picture below.
Classic psychology studies show just how little access we have to the workings of our own minds. Ever wondered where your opinions come from, how you manage to be creative, or how you solve problems? Well, don't bother. Psychology studies examining these areas and more have found that while we're good at inventing plausible explanations, these explanations are frequently completely made-up.
