Thought control: now with letters

Using ECoG (electrocorticography) and overlaying electrodes directly on the surface of the brain, scientists can record reactions when letters are flashed on a screen and then play back the letters when that thought pattern is brought up. It’s around 8 letters per minute, but it’s something.

There’s also a piece where they translate thought patterns into music. An interesting article.

All men watch porn

Prof Lajeunesse interviewed 20 heterosexual male university students who consumed pornography, and found on average, they first watched pornography when they were 10 years old.

Around 90 per cent of consumption was on the internet, while 10 per cent of material came from video stores.

Single men watched pornography for an average of 40 minutes, three times a week, while those in relationships watched it 1.7 times a week for around 20 minutes.

The study found that men watched pornography that matched their own image of sexuality, and quickly discarded material they found offensive or distasteful.

Prof Lajeunesse said pornography did not have a negative effect on men’s sexuality.

“Not one subject had a pathological sexuality,” he said. “In fact, all of their sexual practices were quite conventional.

“Pornography hasn’t changed their perception of women or their relationship, which they all want to be as harmonious and fulfilling as possible,” he added.

Evolving swarm intelligence in robots

The Lausanne university in Switserland has moved from the software to the reality: they’ve managed to get robots to evolve and learn behaviours, as well as the behaviour to decieve and cooperate through communication (flashing lights) and movement. It’ s a very interesting experiment, showing that robots are getting smarter every day and are now showing some very very lifelike traits.

Raise the speed limit!

As an example, Peterson pointed to changes made along a section of Interstate 496 outside of Lansing, which accounted for 40 percent of reported incidents of aggressive driving in that area. When the speed limit was raised from 55 mph to 70 mph, incidents of aggressive driving dropped to zero.

“The low speed limit frustrated many drivers, so they drove over the speed limit. This caused problems for other drivers who were driving at the limit. The speed differential caused the tailgating, passing, and speeding that were reported as ‘aggressive’ driving,” Peterson said.

His data also showed accident rates in that area also fell when the speed limit was raised.

Surprisingly, the higher speed limit also improved traffic flow, nearly eliminating all symptoms of rush hour congestion along that stretch.

Improve Your Posture with Duct Tape

Stand up as straight as you can, with your back vertical and your arms at your sides, relaxed. Then, have a friend take a strip of duct tape and run a three inch strip down your back. The top of it should be on the center of one of your shoulder blades and end three inches below it. Then, that person should put a second strip, starting at the center of your other shoulder blade and going straight down for three inches. Take a third strip and apply it horizontally, connecting the tops of the strips, then a fourth strip connecting the bottoms of the vertical strips. You should have a rectangle on your back, nearly square in shape.

Here’s the thing. As you go through your day, every time you attempt to slouch, that tape will tug at your skin, resisting a poor change in posture. It’s not painful (unless you have excessive hair back there), but it is enough of a physical reminder to cause you to naturally keep a good posture.

Wet Shaving

Who knew there was such a cult around wet shaving? I’ve been wet shaving all my life, but have to admit to using Wilkinson’s Sword or Gilette plastic blades. I’ve got a straight razor, but don’t know how to use it.

Well, there’s more. Much more. Double bladed razors are a kind of in-between thing: they offer a closer shave than a standard safety razor, are a lot cheaper to use (because new blades are very cheap) and are safer than a straight.

Badger & Blade has a lot of reviews of the tools you’ll need. It’s not just the razor, it’s also the blade. And the oil. And the lather. And the brush…

The shave den has a huge amount of information too.

I’ve got my Merkur C-11 and Bluebird Hi-stainless-Platinum blades on order. We’ll see how much I cut my face up!
