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.

Paloma T. Gonzalez-Bellido of Roger Hanlon's Lab in the Marine Resource Center of the Marine Biological Labs helped us with the preparation. You can read their latest paper at:http://rspb.royalsocietypublishing.org/content/early/2012/08/13/rspb.2012.1374

STAR WARS DETOURS™ Trailer

The nine people believed injured by stray police gunfire outside the Empire State Building were not the first to learn how dangerous a crowded street can be in a gunfight.

 Civilians occasionally find themselves in harm's way when officers use deadly force, though usually only a handful of times annually. When that happens, a rigid process of investigation is set in motion — and the police department can reasonably expect a lawsuit. The latest episode came when police say a man disgruntled over losing his job a year ago shot a former colleague to death and pointed his weapon at two police officers in the shadow of a major tourist attraction. He apparently wasn't able to fire before police killed him, one firing off seven rounds and the other nine. Bystanders suffered graze wounds, and some were struck by concrete gouged from buildings by the bullets, authorities said. At least one person said he was actually hit by a bullet. Robert Asika, a 23-year-old tour guide who was hit in the right arm, said he was "100 percent positive" he was shot by a police officer. A witness told police that laid-off clothing designer Jeffrey Johnson fired at officers, but ballistics evidence so far contradicts that, authorities said.

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.

London's secret music venue and their livestream act

With an invite-only door policy and super secret location, Boiler Room is London's most exclusive music venue. But elitism isn't the premise for its clandestine nature—in fact, anyone with an Internet connection can easily join in the fun. Using a simple webcam, the crew behind Boiler Room livestreams each set for the world to see free of charge, and each month more than a million viewers tune in to see performances by artists like James Blake, The xx, Roots Manuva, Neon Indian, Juan Maclean and more.

We recently chilled out to the smooth sounds of Brooklyn's How To Dress Well before rocking out to revered musician Matthew Dear, who brought down the house with an intense 40-minute DJ set. Keep an eye out for our interview with Dear, but for now you can get a little more insight into the underground music scene's most talked about livestream show by checking out our interview with assistant musical programmer and Boiler Room host Nic Tasker.

How important is it for Boiler Room to remain secret, at least in its location?

That is quite an important aspect of it, purely because it means when you do shows you don't get a lot of groupies, pretty much everyone in the room is either a friend of ours or one of the artist's. It helps to create a more relaxed atmosphere for the artist and I think they feel less pressure. They're also just able to chill out and be themselves more rather than having people being like, "Hi can I get your autograph?" If the artists are relaxed usually you get the best music.

It seems like there is more interaction among the crowd than at a typical venue, is that intentional?

It's definitely a social place. All the people that come down, most of them we know and they're all our friends. So they come down, hang, have a drink and just chill out, basically. From our very set-up, we do it with a webcam, we're not a highly professional organization but I think that's kind of the charm of it. The main thing is people come down with the right attitude.

How much of the show is prescribed?

I guess that depends on the artist. We never say anything. Literally, whatever they want to do—we're kind of the platform for them to do whatever they want, so if Matthew Dear wants to come and play an hour of noise with no beats, he can do that. That's fine with us, and I think that's why artists like coming to play for us. We're not like a club where you have to make people dance, we don't give a shit if people dance. It's nice if they do and it makes it more fun, but some nights you just get people appreciating the music, which is equally fun.

Is there a particular kind of artist you guys look for and ask to come perform?

No, not particularly, it's just whatever we're feeling. Thristian [Boiler Room's co-founder] has the main say on musical direction, but it's a massive team effort. In London there's five of us, New York there's two, LA there's one and Berlin there's two.

Tonight you had different set-ups for each artist, do you tailor their positioning in the room to their style?

It definitely depends on the act and what kind of music they do. With live bands we found what works nicely is having them opposite each other because it's like they're in rehearsal, like they're just jamming. Which is again trying to give them that chilled out feel that they're just at home jamming and there happens to be a camera there. For some of our shows we've had over 100,000 viewers. When you think of those numbers it's quite scary, but when you're in the room and it's all friends it creates that vibe that people don't mind. You can imagine if you had all those people in front of you it would be a very different situation.

Have you ever thought of Boiler Room as an East London version of Soul Train?

It's never crossed my mind like that, but I can see why you think that. I like to think of us as the new music broadcaster, kind of the new MTV, but obviously we operate in the underground scene mainly. But I like to think that what we do is as revolutionary as what they were doing. We're always growing into something new.

What's up next for Boiler Room?

We have had visual people in doing 3D mapping, and that's something we're looking forward to progressing—doing more with the visuals. We've got the upstairs as well, we're starting to do breakfast shows with some high profile DJs, we're going to be doing that regularly. Each will have an individual format. The next step is progressing the US shows, we're alternating weekly between New York and LA, so the next step is to take Boiler Room to America

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.

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.UK Citizens

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 behaviors, 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.
