Ecstasy Used for Treating PTSD Proven Effective

[edit: 4 days later, they're covering it on CNN on TV.  Glad to see it's reaching the national media!]
ECSTASY:
Image:Modeling by "Lazord00d"

Surprisingly, a clinical trial using the illegal drug Ecstasy (MDMA) to treat PTSD has proven quite effective.  This should hit home with a lot of people, including myself, since the disorder is so widespread.  Who doesn't know at least a friend of a friend with this disorder?

Just like medical marijuana, an illicit drug if unauthorized, ecstasy may have action on the horizon for medical use.  This would require more studies (and a lot of lawyers of course.)

Ecstasy used in treatment is definitely having an effect.  After the trial, 95% correctly guessed which group (drug or placebo) they were assigned to.
Like a regular study, placebos and X were divvied out.  To quote from the paper's abstract: "The rate of clinical response was 10/12 (83%) in the active treatment group versus 2/8 (25%) in the placebo group."

The finding have great potential for future reduction of suffering.
The credentials to take this seriously are there.  The study is online at NIH.gov, posted from the Journal of Psychopharmacology.  You can read it at the following link:  (Scientists really don't name papers with advertising revenue in mind.)
"The safety and efficacy of ±3,4-methylenedioxymethamphetamine-assisted psychotherapy in subjects with chronic, treatment-resistant posttraumatic stress disorder: the first randomized controlled pilot study"


But what is PTSD like really?
Explained quickly in the original paper's introduction:
"Posttraumatic stress disorder (PTSD) is a debilitating anxiety disorder characterized by re-experiencing, hyperarousal and avoidance symptoms."
Here, the symptoms are described well, but this can be quickly misconstrued if you aren't already familiar with the disorder because of the term hyperarousal.  This Medical Dictionary defines it for us: "Hyperarousal: a state of increased psychological and physiological tension marked by such effects as reduced pain tolerance, anxiety, exaggeration of startle responses, insomnia, fatigue, and accentuation of personality traits."
This describes a great deal of the symptoms, but horribly, not all of the horrors involved for these suffering victims.

Hope is on the horizon.  Bring on the legislature.

I was turned on to this new study by a great blog I'd recommend, Science Based Medicine:
Science-Based Medicine » Ecstasy for PTSD: Not Ready for Prime Time


For another spin, a NY Times Article brings the topic to their huge following of readers:
"A ‘Party Drug’ May Help the Brain Cope With Trauma"



ResearchBlogging.org Mithoefer, M., Wagner, M., Mithoefer, A., Jerome, L., & Doblin, R. (2010). The safety and efficacy of  3,4-methylenedioxymethamphetamine-assisted psychotherapy in subjects with chronic, treatment-resistant posttraumatic stress disorder: the first randomized controlled pilot study Journal of Psychopharmacology, 25 (4), 439-452 DOI: 10.1177/0269881110378371

I try to keep up with NASA, ESO, ESA, even ArXiv, when they lag behind in social media and forget to upload to YouTube.  Sometimes copyright statements are clear and I can do it on my own.  Sometimes I have to contact the scientists.

Here are some new videos I have recently put up on my YouTube Channel.

"NASA - (Narrated) Learn What LRO Has Learned About Linne Crater"
"If you want to learn more about the history of Earth and other rocky planets in the solar system, craters are a great place to look. Now, thanks to LRO's LROC instrument, we can take a much closer look at Linn? Crater on the moon--a pristine crater that's great to use to compare with other craters!"

4 of the Newest and Coolest Videos Out of NASA

-----Share this specific url.
Share Spread the Love

Straight from my YouTube Channel, here are the latest and greatest, some incredible new videos just released on NASA's website.

First,
  "NASA and Japan Team Together To Launch Satellite (Animation)"
Nine U.S. and international satellites will soon be united by the Global Precipitation Measurement (GPM) mission, a partnership co-led by NASA and the Japan Aerospace Exploration Agency (JAXA). NASA and JAXA will provide the GPM Core satellite to serve as a reference for precipitation measurements made by this constellation of satellites, which will be combined into a single global dataset continually refreshed every three hours.

"NASA's Animated Dynamics of Hurricane Bonnie"
This animation of Hurricane Bonnie uses data from NASA's TRMM Satellite. Beginning with a wide view of the world, we zoom in on a swath of atmosphere taken by TRMM. Then we go inside and see how the actual dynamics of the hurricane are at work.

"NASA Explains The Eye of a Hurricane and Hurricane Dynamics"
Rapid changes in wind speed and vortexes are all involved in this voiceover animation explaining hurricane dynamics.

"NASA Animation - Gamma Rays Hit Satellite"
This animation tracks several gamma rays through space and time, from their emission in the jet of a distant blazar to their arrival in Fermi's Large Area Telescope (LAT). During their journey, the number of randomly moving ultraviolet and optical photons (blue) increases as more and more stars are born in the universe. Eventually, one of the gamma rays encounters a photon of starlight and the gamma ray transforms into an electron and a positron. The remaining gamma-ray photons arrive at Fermi, interact with tungsten plates in the LAT, and produce the electrons and positrons whose paths through the detector allows astronomers to backtrack the gamma rays to their source.

Science Based Medicine's new article "Cyborg Therapeutics" brings to light some absolutely stunning robotics developed for the handicapped.  I'll share with you some media on these innovations.

First to see is the iBot.  I'm heartbroken to discover that this product is discontinued.  
The Segue-Meets-Wheelchair device is otherworldly,
a seemingly sci-fi creation,

A second innovation, reported out of Vanderbilt University, is perhaps even more impressive.  A lower body exoskeleton has been designed for paraplegics.  It also uses a segue-related technology and is slated for release in 2014.  Using minor hip movements you can drive these prosthetic legs that are powered by lithium batteries and run by micro-computers.  Watch one man proudly walk on his own, overcoming a devastating car accident that injured his spine and ruined his legs:

Info on the project from DARPA's .mil site:
"The Department of Defense’s strategic plan calls for the Joint Force to conduct humanitarian, disaster relief and related operations.  The plan identifies requirements to extend aid to victims of natural or man-made disasters and conduct evacuation operations.  Some disasters, however, due to grave risks to the health and wellbeing of rescue and aid workers, prove too great in scale or scope for timely and effective human response.  The DARPA Robotics Challenge (DRC) will attempt to address this capability gap by promoting innovation in robotic technology for disaster-response operations."

The Human Microbiome

I hope you enjoyed the poll I posted for this article!  
63% of you 
thought micro-organisms comprised 3-5% of our body mass.
Close!
It's 1-3%

In the human body, we are host to a variety of 100 TRILLION different microbes.
New York Times: [link]
Discover Magazine says 200 Trillion [link]




NIH.gov says that, startlingly, the ratio in the body, is only ONE human cell to TEN foreign micro-organisms.  [link]
Discover Magazine says 20 to 1. [link]


A whopping 1-3% of your total body mass is not you.
So for a 200lb. man, 2lb. to 6lb. of your weight are other living things.
It's bacteria, fungus, and other lovely little "beasties."
Again, National Institute of Health: [link]


These organisms are all over us.  Almost all of them are harmless.  Bacteria comprises much, but others are there, such as fungi.  500-1000 different species of bacteria alone live in the gut alone.
Human Biome on Wikipedia: [http://en.wikipedia.org/wiki/Human_microbiome]


Beyond the gut, the skin and mouth are teeming with life.  Even further, we are simply covered.

Germophobes, I'm sorry to tell you, your goals may be far beyond your reach.

DARPA's Amphibious CAAT Trumps Hovercrafts

------
Man, I love DARPA.  
This 4 ton MONSTER, the CAAT (Captive Air Amphibious Transporter) makes a hovercraft look like a horse and buggy.

It's such a simple idea that I can barely believe it works so well.  It's the basic idea of a tank with "pontoon" treads.  Simple as that.  Now I'm sure there's a heck of a lot more involved in the research, development, and engineering, but the basic idea is SO BASIC it blows my mind.

Check this big guy out.

Real Time Travel - Einstein Discovered Time Dilation

------
Einstein's Special Relativity included the discovery that physical speed slows time.  The first definitive experiment was done very simply.  There were two synced atomic clocks.  One was stationary.  The other was sent in a jet that flew around the world and back.  It turned out that yes, there was a time discrepancy after all.  THEN people really started to pay attention.

This video talks a bit about REAL time travel, the proven kind, which is actually called Time Dilation.

DARPA Puts Out Flames With Speakers

It almost seems like this news story was tailored just for me!

DARPA

+

FIRE
 
+

AUDIO

Yes, I'll take it, thank you.

DARPA started the Instant Fire Suppression Program (IFS) in 2008.  Round 2, which we'll see in a second, uses audio; but the first method out of this program was a "flame-suppression system that used a handheld electrode to suppress small methane gas and liquid fuel fires."

The second phase, using acoustics, was developed in 2011.
This video below shows something new and quite amazing. The exact description of what's going on here is very hard to reword, so here is their explanation:

"First, the acoustic field increases the air velocity. As the velocity goes up, the flame boundary layer, where combustion occurs, thins, making it easier to disrupt the flame. Second, by disturbing the pool surface, the acoustic field leads to higher fuel vaporization, which widens the flame, but also drops the overall flame temperature. As the same amount of heat is spread over a larger area, combustion is disrupted."

Huge List Of Debates And Lectures On Theology And Science

This floated my way somehow, supposedly originating from Reddit.  Almost all of these are religious debates/lectures, but a few are simply science.  This list will last me a hell of a long time.  My late nights are now pretty much now taken care of!  I can only imagine how many hours are in here.

Listed fifth from the bottom happens to be my favorite lecture of all time:
Lawrence Krauss - A Universe From Nothing. (on cosmology)

**DISCLAIMER**  I have NOT watched them all; so I cannot outright endorse them as a lot.  Furthermore, I have not tested each link.


However, what's important to note is that these people are well known to be highly educated, have phenomenal credentials, and are supremely eloquent.


Pick and choose AND ENJOY!
