The 2004 Nimitz UFO Incident

Very long, fascinating story short: The USS Nimitz UFO incident was a radar-visual encounter with an unidentified flying object by U.S. fighter pilots of the Nimitz Carrier Strike Group in 2004.

A New York Times front page story on the incident, published on December 16, 2017, caused a firestorm of reaction.

Last week Chad Underwood, a Navy pilot whose plane's radar recorded the footage of the UFO that appears in the video up top, for the first time ever spoke publicly about what he saw that day in an interview that appeared in New York magazine. 

Watch, listen, and wonder.

What people notice first when they meet someone


Above, a graphic from USA Today.

You might want to take the findings with a grain of salt, in the spirit of the law of the instrument, to wit: "To a hammer everything is a nail."

Consider the fine print at the bottom of the graphic: "Source: ORC for Philips Sonicare survey of 1,008 American adults."

Philips Sonicare makes high-end products for — guess what? — teeth.

In the same vein, if optometrists funded a study we wouldn't be too shocked to find it concluded the eyes are the most frequently noticed feature.

And Dhani Jones would likely find that smell is the category leader.

Caveat odore.

BehindTheMedspeak: "Tattoo-Induced Skin Burn During MR Imaging"

Say what?

Not an Onion story but a real case report, published in the American Journal of Radiology in 2000.

Don't believe me?

Read it yourself below.

Tattoo-Induced Skin Burn During MR Imaging

MR-induced skin burns caused by permanent coloring techniques (tattooing) are extremely rare. Eyeliner materials containing metallic substances are known to cause artifacts on cranial MR studies, but rarely is the patient affected.

A 23-year-old man sustained a second-degree skin burn in two skin tattoos while undergoing cervical spine MR imaging at 1.5-T using a phased array coil. The study consisted of a sagittal spoiled gradient-refocused acquisition in the steady state localizer (23 sec), sagittal T1-weighted spin-echo imaging (3 min 44 sec), sagittal T2-weighted fast spin-echo imaging with multiple (16) 180° radiofrequency (RF) pulses (3 min 16 sec), and axial multiplanar gradient-re-called sequences using gradient acquisition with a 20° flip angle (4 min 23 sec). At the end of the examination the patient complained of a burning sensation in his right deltoid area, which was raised and swollen. The patient was treated in the emergency department for a second-degree skin burn and returned 24 hr later, when multiple color photographs were obtained.

The burns occurred only in the two jet-black thunderbolt tattoos, but not in the Chinese symbol. Although his shoulder may have touched the wall of the magnet, the Chinese symbol tattoo did not cause him to be burned at all. The two adjacent thunderbolt tattoos could have approximated an RF pick-up loop and therefore would have been more prone to preferentially absorb the RF energy.

The tattoo studio was contacted, and the artist stated that all the ink used in their studio was obtained from a single national supplier. He also stated that he had never had a client complain of a skin burn caused by MR imaging. The major supplier of tattoo ink in the United States is Spaulding & Rogers Manufacturing, located outside Albany, NY. A spokesperson for that company stated that the Food and Drug Administration does not give its approval to the use of tattoo ink. Extremely dark tattoo ink contains a high concentration of iron oxide, and this ferrous pigment can become quite concentrated if sedimented ink is used during the tattoo process. He also stated that there is little quality control over foreign-manufactured tattoo ink, especially from China, which is a major international supplier of tattoo ink.

Artistic tattoos have now become mainstream and are no longer found exclusively on sailors and bikers. The tattoos are often very fine and intricate and do not typically use high concentrations of jet-black ink. Iron oxide is both potentially magnetic and an electrical conductor; therefore, the heating could come either from the oscillations of the gradients or, more likely, from the RF-induced electrical currents. Heating raises intracellular water temperature in the skin, resulting in a burn.

In 14 years of experience with thousands of MR studies, we have never had a single skin burn caused by tattoo ink. This report provides graphic proof that a tattoo can potentially cause a second-degree skin burn, particularly if the ink is concentrated (dark) or if the tattoo is in the form of an RF pick-up loop.

It's amazing, the medical knowledge you can gain by a close reading of the Wall Street Journal, where I learned of this report.
