afk, back next week. Qcard?

Off to Avenue Q, then Hawaii.

Back after Labor Day.

In the meantime, enjoy a Qcard (PG-13+).

GREENDIMES: junk mail reduction service

I wonder how well this actually works?

Sounds like a wonderful concept. Pay $15 for a kit with forms you fill out and send in, they do the rest.

Their FAQ claims that they can even stop mail addressed to 'Occupant', 'Resident', and the like.

Free online Database of U.S. Court Decisions

Yay! Welcome to the age of truly accessible knowledge, making law accessible to the masses.

From physorg:
Aiming to make federal case law fast and easy to search, more accessible to the public – and free – Columbia Law School and the University of Colorado Law School have launched a Web site called AltLaw.org, which has the potential to transform the national landscape of case law resources.
Check it out at http://altlaw.org/.


Musical perception (take a test!) and tone deafness

Apparently, there are some measurable music 'areas' in the brain.

From Science Daily:
In a study comparing amusics to people with normal musical ability, researchers used a brain imaging and statistical technique to measure the density of the white matter (which consists of connecting nerve fibers) between the right frontal lobe, where higher thinking occurs, and the right temporal lobes, where basic processing of sound occurs. The white matter of the amusics was thinner, which suggests a weaker connection. Moreover, the worse the tone deafness, the thinner the white matter.

To participate in a music perception test study online, check out http://www.delosis.com/listening developed by researchers at the University of Newcastle-upon-Tyne in England.

This site also has tests for rhythm and adaptive pitch: http://tonometric.com/adaptivepitch/

Inducing Out of Body Experiences on Demand

Through the goggles, the volunteer is viewing the back of his body, as seen from behind by the camera. He is also watching a plastic rod moving toward a location just below the camera while his real chest is simultaneously touched in the corresponding spot. (Image courtesy of Henrik Ehrsson/Science)

From physorg:

Using virtual reality goggles to mix up the sensory signals reaching the brain, scientists have induced out-of-body-like experiences in healthy people, suggesting a scientific explanation for a phenomenon often thought to be a figment of the imagination.
What they did:

Both Ehrsson and another research team, led by Olaf Blanke of the Ecole Polytechique Fédérale de Lausanne (EPFL) and the University Hospital in Geneva, Switzerland, used video cameras and virtual reality goggles to show volunteers images of their own bodies from the perspective of someone behind them...
Ehrsson had the volunteers watch a plastic rod moving toward a location just below the cameras while their real chests were simultaneously touched in the corresponding spot. Questionnaire responses afterwards indicated that the volunteers felt they were located back where the cameras were placed, watching a dummy or a body that belonged to someone else.
Ehrsson also had the volunteers watch a hammer swing down to a point below the camera, as though it were going to “hurt” an unseen portion of the virtual body. Measurements of skin conductance, which reflects emotional responses such as fear, indicated that the volunteers sensed their “selves” had left their physical bodies and moved to the virtual bodies.
And what did they conclude?

“multisensory conflict” is a key mechanism underlying out-of-body experiences...
“This experiment suggests that the first-person visual perspective is critically important for the in-body experience. In other words, we feel that our self is located where the eyes are,” Ehrsson said.
Very cool! This brings us another step closer to creating better virtual reality, where you will someday feel like you are somewhere your physical body is not.

GPS enabled platform shoes, marketed to sex workers

Strange but true.
According to gizmag:
With an inbuilt GPS, an audible alarm system and storage for your valuables the Platform 001 sandals could definitely be beneficial in protecting against muggings or to locate ladies in the case of emergency.
Specifically aimed at sex workers the shoes are the brainchild of the Aphrodite Project in response to an ever growing number of attacks against women in the industry. The shoe - aptly named The Platform 001 - was inspired by the prostitutes of ancient Greece and Rome, who enticed clients with their flutes and sandals that left ‘follow me’ footprints in the earth.
And some more features of these shoes:

Functionality of the Platform shoe includes a 3.5 inch LCD monitor with audio and text overlay for promotion to clients whilst safety features include an audible alarm, secure storage compartments and a panic button connected to monitored GPS tracking for use in case of an emergency. The design does raise some safety concerns since they are being promoted as a "safety shoe" with secret storage, potential attackers could become familiar with the design and specifically target those with the shoes thinking them to be carrying valuables. Further, the clumsiness of the shoe could pose a problem in a situation whereby the wearer needed to run at any great speed.
Building a GPS into a shoe seems like a great idea, especially for young children and other vulnerable populations. Having a 3.5 inch LCD monitor built into your shoe is just bizarre to me, but I guess it definitely draws attention to the bling. Who knows, maybe someday we'll all be covered in monitors, from our t-shirts down to our platform shoes.

Magnetic brain scans to diagnose common brain diseases in 60 seconds

From Science Daily:

By comparing the patterns of tiny magnetic charges in healthy brains to those afflicted with common diseases such as Alzheimer's, the team has been able to identify the patterns commonly associated with these debilitating diseases [multiple sclerosis, Alzheimer's and schizophrenia].

How?
A process called magnetoencephalography (MEG), a non-invasive measurement of magnetic fields in the brain, has been used to examine a total of 142 volunteers during tests which last between 45-60 seconds. The team first studied 52 volunteers to find patterns of neural activity that could identify all the different illnesses. They then tested a further 46 patients to see whether the patterns found from the first group could accurately diagnose disease within a second group. Here, many of the predictors found from the first set of participants also correctly diagnosed more than 90% of subjects in the second sample.

The theory?

All behavior and cognition in the brain involves networks of nerves continuously interacting--these interactions occur on a millisecond by millisecond basis. The MEG has 248 sensors that record the interactions in the brain on a millisecond by millisecond basis, much faster than current methods of evaluation such as the functional magnetic resonance imaging (fMRI), which takes seconds to record. The measurements they recorded represent the workings of tens of thousands of brain cells.
Wow. I hope it works out, this would be an awesome tool for diagnosing, and thereby helping us choose treatments for some difficult to treat diseases.
