During experiments on the axons of the Woods Hole squid (loligo pealei), we tested our cockroach leg stimulus protocol on the squid's chromatophores.
The results were both interesting and beautiful. The video is a view through an 8x microscope zoomed in on the dorsal side of the caudal fin of the squid. We used a suction electrode to stimulate the fin nerve. Chromatophores are pigmeted cells that come in 3 colors: Brown, Red, and Yellow. Each chromatophore is lined with up to 16 muscles that contract to reveal their color.

Tracking a Rare Tattoo-Related Infection
A Trail of Ink: Tracking a Rare Tattoo-Related Infection
An uncommon skin infection led to a doctor's investigation into tainted tattoo ink. (Monroe County Health Department)
The reddish-purple rash, seemingly woven into the tattoo on a 20-year-old New Yorker's forearm, was strange enough to have doctors scratching their heads.
This trail began when the man received a tattoo in Rochester, N.Y. in October 2011. A short while later, he noticed the raised, bumpy rash. He called his primary care physician.
Doctors initially treated the man's arm with topical steroids, thinking that the rash was allergic-contact dermatitis. But that only made the problem worse.
By the time dermatologist Dr. Mark Goldgeier saw the patient, it was clear that this was no simple allergy.
He performed a skin biopsy so he could take a closer look at the rash under a microscope. What he saw was startling: the sample was riddled with a wormlike bacterium related to tuberculosis.
"I explained [to the patient] that he had TB, and he had a look of horror on his face," Goldgeier said.
For the patient, the finding meant a trip to an infectious disease specialist to start up to a full year of treatment.
Goldgeier, meanwhile, called the Monroe County Health Department.
"As soon as biopsy came back," he said, "I knew something in the process of tattooing was involved -- the ink, the water used for dilution, the syringes, the dressings."
And so began a nationwide medical mystery.
An article published Wednesday in the New England Journal of Medicine describes how this one dermatologist helped connect the dots in an outbreak of tattoo-related atypical skin infections.
Dr. Byron Kennedy, public health specialist at Monroe County Department of Public Health, took over the case from Goldgeier. Kennedy first confirmed the results by repeating a skin biopsy on the patient. Once again, tendrils of mycobacterium chelonae, a type of tuberculosis-related skin bacteria, showed up in the sample.
Mycobacterium chelonae is a rapidly growing bug found in soil, dust, water, animals, hospitals, and contaminated pharmaceuticals. This family of bacteria does not commonly affect healthy individuals, but in patients with suppressed immune systems -- like those with HIV or on chemotherapy -- these bacteria can cause serious disease, often resulting in death.
The finding sent Kennedy and his associates to the tattoo parlor where the patient had been inked. Everything in the clinic was sterile, which made it unlikely that the infection had arisen there. But the tattoo artist, they learned, had been using a new gray premixed ink purchased in Arizona in April 2011; he used the ink between May and December 2011.
The ingredients of the ink -- pigment, witch hazel, glycerin, and distilled water -- seemed innocuous enough. But further examination revealed that the distilled water in the pigment was the likely culprit of the contamination.
The finding raised a number of questions -- not the least of which was how the bottles of premixed ink passed U.S. Food and Drug Administration regulations.
The U.S. Centers for Disease Control and Prevention acknowledged this gap in regulations Wednesday in its Morbidity and Mortality Weekly report.
"Under the Federal Food, Drug, and Cosmetic Act, tattoo inks are considered to be cosmetics, and the pigments used in the inks are color additives requiring premarket approval," the report says.

Addiction Books For relaxation When 50 Shades of Grey doesn’t cut it.
The Science of Addiction: From Neurobiology to Treatment
Carlton K. Erickson
312 pages
Publisher: W. W. Norton and Company (2007)
Amazon Overview: Neuroscience is clarifying the causes of compulsive alcohol and drug use––while also shedding light on what addiction is, what it is not, and how it can best be treated––in exciting and innovative ways. Current neurobiological research complements and enhances the approaches to addiction traditionally taken in social work and psychology. However, this important research is generally not presented in a forthright, jargon-free way that clearly illustrates its relevance to addiction professionals. In The Science of Addiction, Carlton K. Erickson presents a comprehensive overview of the roles that brain function and genetics play in addiction.
The Addiction Solution: Unraveling the Mysteries of Addiction through Cutting-Edge Brain Science
David Kipper and Steven Whitney
304 pages
Publisher: Rodale Books (2010)
For decades addiction has been viewed and treated as a social and behavioral illness, afflicting people of “weak” character and “bad” moral fiber. However, recent breakthroughs in genetic technology have enabled doctors, for the first time, to correctly diagnose the disease and prove that addiction is an inherited, neuro-chemical disease originating in brain chemistry, determined by genetics, and triggered by stress. In their groundbreaking Addiction Breakthrough, David Kipper, MD, and Steven Whitney distill these exciting findings into a guide for the millions of adults who want to be free from the cycle of addiction, and for their loved ones who want to better understand it and to help.
In the Realm of Hungry Ghosts: Close Encounters with Addiction
Gabor Maté
520 pages
Publisher: North Atlantic Books (2010)
Based on Gabor Maté’s two decades of experience as a medical doctor and his groundbreaking work with the severely addicted on Vancouver’s skid row, In the Realm of Hungry Ghosts radically reenvisions this much misunderstood field by taking a holistic approach. Dr. Maté presents addiction not as a discrete phenomenon confined to an unfortunate or weak-willed few, but as a continuum that runs throughout (and perhaps underpins) our society; not a medical "condition" distinct from the lives it affects, rather the result of a complex interplay among personal history, emotional, and neurological development, brain chemistry, and the drugs (and behaviors) of addiction. Simplifying a wide array of brain and addiction research findings from around the globe, the book avoids glib self-help remedies, instead promoting a thorough and compassionate self-understanding as the first key to healing and wellness.
Memoirs of an Addicted Brain: A Neuroscientist Examines his Former Life on Drugs
Marc Lewis
336 pages
Publisher: PublicAffairs (2012)
Marc Lewis’s relationship with drugs began in a New England boarding school where, as a bullied and homesick fifteen-year-old, he made brief escapes from reality by way of cough medicine, alcohol, and marijuana. In Berkeley, California, in its hippie heyday, he found methamphetamine and LSD and heroin. He sniffed nitrous oxide in Malaysia and frequented Calcutta’s opium dens. Ultimately, though, his journey took him where it takes most addicts: into a life of addiction, desperation, deception, and crime. But unlike most addicts, Lewis recovered and became a developmental psychologist and researcher in neuroscience. In Memoirs of an Addicted Brain, he applies his professional expertise to a study of his former self, using the story of his own journey through addiction to tell the universal story of addictions of every kind.
The Chemical Carousel: What Science Tells Us About Beating Addiction
Dirk Hanson
472 pages
Publisher: BookSurge (2009)
A book for anyone concerned with the care and healing of addiction, substance abuse, and the latest advances in the area of addiction science. In The Chemical Carousel, science writer Hanson takes the reader on a voyage through the heady world of addiction science, from the lab to the clinic to the junky on the street. Hanson explains the workings of common neurotransmitters and documents the direct effect drugs and alcohol produce on the reward pathways of the brain. He shows how scientists and treatment professionals have finally given us an answer to the perennial question about addiction: Why can't those people just say no?
An Anatomy of Addiction: Sigmund Freud, William Halsted, and the Miracle Drug, Cocaine
Howard Markel
336 pages
Publisher: Vintage (2012)
Acclaimed medical historian Howard Markel traces the careers of two brilliant young doctors--Sigmund Freud, neurologist, and William Halsted, surgeon--showing how their powerful addictions to cocaine shaped their enormous contributions to psychology and medicine. When Freud and Halsted began their experiments with cocaine in the 1880s, neither they, nor their colleagues, had any idea of the drug's potential to dominate and endanger their lives. An Anatomy of Addiction tells the tragic and heroic story of each man, accidentally struck down in his prime by an insidious malady: tragic because of the time, relationships, and health cocaine forced each to squander; heroic in the intense battle each man waged to overcome his affliction.

Will the real God please stand up?
Some people are slow learners. I am one of them. I have made the same mistake countless times. And every single time, that's right, you've got it. It happens every time. Maybe I should be more careful when I place my trust, expectation, hope, and confidence in a human being. Maybe I should be more choosy with the human I choose. Not so. No matter the human, the same outcome will arise. My god will fail me. I did it again recently. I made the same mistake. But my mistake wasn't the human I chose.
My mistake was the choice I made to pick a human. And guess what happened? You guessed it. My god failed me. But how can this happen, time and again? Easily. First, it happens when I fail to remember when I need not to forget. Never, ever, place what belongs to God in heaven in the hands of a human. My love and trust, my loyalty and faithfulness, my belief and confidence, my hope and expectation, must be placed in the Lord first and foremost, above all and everyone else - whether it be someone or something else, or whether it be myself. Second, it happens not because I forget, but because I don't realise and recognise what I have done. Hard habits sometimes die slowly, don't they? And slow habits die hard.
It has been a hard lesson for me, and I have to be vigilant to ensure I don't unconsciously do what I have so often done. So what is the outcome of this all? My gods fail me. Every human I have ever made into a god, every person or thing I have ever turned into an idol, the result has always been the same. My false gods have failed me, hurt me, let me down, forsaken me, abandoned me, rejected me, broken me, fallen short, messed up, and a zillion other things. Seriously? Yes. Will the real God please stand up?

The first key of mindful communication, is having a mindful presence.
You are fully in the present moment; our communication isn’t focused on the “me” and what the “me” needs, but the we.
Mindful listening is the second key to mindful communication. Mindful listening is about encouraging the other person. This means looking through the masks and pretense and seeing the value in the person and the strengths he or she possesses. It’s looking past the human frailties and flaws that we all have to see the authentic person and the truth in what that person is attempting to say.
Mindful speech, the third key, is about gentleness. Speaking gently means being effective in what you say. It’s about speaking in a way that you can be hard. To be gentle with our speech means being aware of when our own insecurities and fears are aroused to the point we are acting out of fear rather than acceptance.
Practicing self-compassion for our fear, envy, jealousy and self-doubts is more effective than focusing on others as being a threat or attempting to change them. When you use gentle speech, you are communicating acceptance to the other person and saying what is true, not an interpretation or an exaggeration or a minimization.
The key to mindful relationships is unconditional friendliness. Unconditional friendliness means accepting the ebb and flow of relationships. Sometimes you meet new friends, sometimes friends move on, sometimes there is joy and sometimes there is pain. Sometimes you’ll feel lonely, sometimes you’ll feel cherished and connected, and then you’ll feel lonely again.
Unconditional friendliness means that your acceptance of others is not dependent on them staying with you or agreeing with you. You don’t cling to relationships to avoid loss.
Mindful responsiveness is like playfulness. Playfulness is the openness that you can have when you let go of preconceived ideas and strategies. It’s like creating something new. Imagine two skilled dancers who alternatively lead each other in creating a new dance in every interaction, never doing the same complete dance over and over. They respond in the moment to the message sent by the other. There are no rules or expectations and yet they both bring skillful behavior.
Mindful communication requires practice. If you choose to practice the keys, you might choose to focus on one at a time. Being willing to regulate your emotions is a prerequisite to mindful communication and mindfulness of your emotions is necessary for emotion regulation.
Mindfulness is a core skill for the emotionally sensitive.

Breaking Free of the Co-dependency Trap presents a groundbreaking developmental road map to guide readers away from their co-dependent behaviors and toward a life of wholeness and fulfillment.
This is the book that offers a different perspective on codependency and is strongly recommended by Dream Warrior Recovery as part of a solution based recovery. This bestselling book, now in a revised edition, radically challenges the prevailing medical definition of co-dependency as a permanent, progressive, and incurable addiction. Rather, the authors identify it as the result of developmental traumas that interfered with the infant-parent bonding relationship during the first year of life.US Citizens
Drawing on decades of clinical experience, Barry and Janae Weinhold correlate the developmental causes of co-dependency with relationship problems later in life, such as establishing and maintaining boundaries, clinging and dependent behaviours, people pleasing, and difficulty achieving success in the world. Then they focus on healing co-dependency, providing compelling case histories and practical activities to help readers heal early trauma and transform themselves and their primary relationships.

If ever there was a god to prevent you from worshiping material things, it would be this one.
The hideous pig-like thing is the masterpiece by Chinese artist Chen Wenling called God Of Materialism.
Ugly pig with green eye darting at their master
Looking chuffed, the huge greedy pig has minions of other tiny, and just as unattractive and scary, pigs worshiping in awe at its heels.
The group stare up at their master, adorned with a plethora of jewels and necklaces representing the grotesque love of material things.
The sculpture, which looks like a bad dream, can be found at the Asia Art Centre in Beijing.
And if you're brave enough to go and see it, it will be there till October 18th 2008.
