Dorsolateral prefrontal cortex Psychlopedia -- Key concepts -- Biological concepts -- Dorsolateral prefrontal cortex Jump to the comments Section Overview The dorsolateral prefrontal cortex, together with other connected areas, is assumed to be important in working memory and executive function--including the regulation of thinking and action. Damage to this region provokes dysexecutive syndrome. Roles of the dorsolateral prefrontal cortex and ventrolateral prefrontal cortex The difference between the dorsolateral prefrontal cortex and the ventrolateral prefrontal cortex aligns to the disparity between the dorsal and ventral pathways in the cortex, according to O'Reilly (2010). The dorsal pathways primarily terminate in the dorsolateral prefrontal cortex instead of the ventrolateral prefrontal cortex. The ventral pathways primarily terminate in the ventrolateral prefrontal cortex instead of the dorsolateral prefrontal cortex. O'Reilly (2010) accumulated considerable evidence to support this contention. Memory Mood
Mad science News, Videos, Reviews and Gossip - io9 About 60 years late to the party on dreaming that one up, friend. :-) in short...solar power is inefficient, and electrolysis of water to create hydrogen is energy intensive, which means it wastes a lot of energy to create that hydrogen to be used as an energy source. IIRC electrolysis is at best 50% energy efficient, with solar being 20% efficient at converting sunlight to electricity, which has a decent, but low yield in the first place. Fuel cells convert something like 60% of stored energy into actual mechanical, lets get this thing moving energy...so we're down to 19.2W of energy used via hydrogen fuel cells filled using every square meter of solar cells we use. We could do it, but as you can see we lose a lot of energy in the process.
Biohack Yourself | Transcend Your Limits The Elements by Theodore Gray My book The Elements is based on photographs I've been collecting at my website periodictable.com for many years. The website includes not just pictures, but also more detailed descriptions than we could fit in the book, and most importantly, it includes full 360-degree rotating videos of almost all the objects. You really won't find this kind of resources anywhere else for any other subject, so please enjoy. If you don't have the book yet, please don't think this is page is a substitute for the real thing. For the convenience of people who have the book, I've listed all the samples found on each page in the book, so you can easy look them up.

Why you should learn to lucid dream | Yes, I Can! by Robin Nixon If you’ve never experienced it then you may find it hard to understand what lucid dreaming is all about. In fact you may be thoroughly sceptical and dismiss the whole thing as silly nonsense. But I can tell you from personal experience that lucid dreams are very real and something that many millions of people regularly enjoy. Note: Due to the huge amount of interest that this post has generated I am now seriously considering writing a book on the subject, and I would welcome input from anyone with an interest. These types of dreams are hyper-real in that when you experience one it is bursting with vibrant colour, there’s often marvellous music playing in the background (if you listen for it), the air is the freshest and sweetest you’ve ever smelled, and you are the healthiest you have ever been (or could ever be). Lucid dreaming is when you experience full consciousness while dreaming. When you ‘wake up’ inside a dream you can consciously appreciate just how wonderful dreams really are.
Brain Scanner Records Dreams on Video Just a few weeks ago, we posted about how brain patterns can reveal almost exactly what you're thinking. Now, researchers at UC Berkeley have figured out how to extract what you're picturing inside your head, and they can play it back on video. The way this works is very similar to the mind-reading technique that we covered earlier this month. With this database in place, the Berkeley research group was then able to feed brain scans into their computer model, which would go pick out the 100 video clips that most closely matched the brain pattern on a second-by-second basis. Comparing the brain-scan video to the original video is just a way to prove that the system works, but there's nothing stopping this technique from being used to suck video out of people's heads directly. Of course, from a slightly more sinister angle, it's also possible someone could put you in an fMRI machine and suck your memories out. Berkeley, via SciAm and io9

Video: A Trillion-Frame-Per-Second Camera Captures Individual Photons Moving Through Space Here at PopSci we love super-fast cameras and super slow-mo video, so you can imagine our glee when we heard that MIT researchers have built a camera with a visual capture rate of one trillion frames per second. That's fast enough to watch photons travel the length of a one-liter bottle in the video below. In other words, absolutely nothing in the universe looks fast to this camera. But it's not so simple as pressing "record." The rig is built as a "streak camera," a fairly new innovation in which the aperture of the camera is a narrow slit. The result is a frame captured very quickly, but it is only one-dimensional, at least from a spatial standpoint. So how do they produce the 2-D video below? In other words, the world's fastest video camera is also very slow, as it must first accumulate hundreds of thousands of data sets before it can cobble together a short video of a scene like the one seen below.

I dunno, we've got much more targeted, devastating methods of wiping ourselves off the planet these days. I was in in the 90's. The husband, Mr.
Lucid Dreaming Frequently Asked Questions Answered by The Lucidity Institute Version 2.4 © Lucidity Institute (contact us) This FAQ is a brief introduction to lucid dreaming: what it is, how to do it, and what can be done with it.

We Can Survive Killer Asteroids — But It Won't Be Easy | Wired Science The chances that your tombstone will read “Killed by Asteroid” are about the same as they’d be for “Killed in Airplane Crash.” Solar System debris rains down on Earth in vast quantities — more than a hundred tons of it a day. Most of it vaporizes in our atmosphere, leaving stunning trails of light we call shooting stars. More hazardous are the billions, likely trillions, of leftover rocks — comets and asteroids — that wander interplanetary space in search of targets. Most asteroids are made of rock. The rest are metal, mostly iron. But some do. Every few decades, on average, house-sized impactors collide with Earth. One killer asteroid we’ve been monitoring is Apophis, which is large enough to fill the Rose Bowl. If humans one day become extinct from a catastrophic collision, we would be the laughing stock of aliens in the galaxy Some people would like to blow potentially hazardous rocks out of the sky with a nuclear bomb. Saving the planet requires commitment. Opinion Editor: John C.
Brain Zaps Can Trigger Lucid Dreams Lucid dreams, in which people are aware of and can control their dreams, are rare. But now scientists have found they can induce this weird state of mind in people by zapping their brains with a specific frequency of electricity. "I never thought this would work," said study researcher Dr. John Allan Hobson, a psychiatrist and longtime sleep researcher at Harvard University. The results showed that when the inexperienced dreamers were zapped with a current of 40 Hertz, 77 percent of the time these participants reported having what were described as lucid dreams. "They were really excited," said study researcher Ursula Voss, of J.W. Dream waves A lucid dream can be thought of as an overlap between two states of consciousness — the one that exists in normal dreaming, and the one during wakefulness, which involves higher levels of awareness and control. Such overlap is also reflected in the brain waves that researchers can detect using electroencephalography, or EEG. Science of consciousness
