Ötzi's tattoos


The existence of the tattoos on an ice age man is not particularly surprising, nor are they artistically interesting -

- but their distribution, as reported in an io9 article, is fascinating:
On account of the various locations of the tattoos, some researchers suspected that the marks were part of some therapeutic medical treatment, a kind of acupuncture to relieve pain in the joints.
The article notes that the tats were created not with a needle, but by making a laceration and then rubbing charcoal into it.

In 2011 I wrote a post entitled The Face of Ötzi the Iceman regarding a recently-completed forensic reconstruction.  At that time reader Judyofthewoods offered the opinion that these tattoos marked acupuncture or acupressure points.  She offered a link to a relevant article in Acupuncure Today:
Experts from three acupuncture societies then examined the locations of the tattoos. In their opinion, nine tattoos could be identified as being located directly on, or within six millimeters of, traditional acupuncture points. Two more were located on an acupuncture meridian. One tattoo was used as a local point. The remaining three tattoos were situated between 6-13mm from the closest acupuncture point.

"I ate his liver with some fava beans and a nice chianti."

The title is Hannibal Lecter's famous line from Silence of the Lambs.  I learned at the movies subreddit that there is a subtle implication:
Lecter could be treated with drugs called monoamine oxidase inhibitors - MAOIs. As a psychiatrist, Lecter knows this.

The three things you can't eat with MAOIs? Liver, beans, wine.

Lecter is a) cracking a joke for his own amusement, and b) saying he's not taking his meds.

The average American moves 11.4 times

The last time the Census Bureau calculated this was in 2007, when it found that a typical American will move 11.7 times in their lives. We redid the math using the most recent data (2013 for mobility and 2010 for population estimates) and reached a slightly lower number of 11.3 lifetime moves.
I have moved 11 times in my lifetime (8 cities in 8 states).  I thought that was unusual.  Not so.

An article at FiveThirtyEight focuses on field-goal kicking accuracy rather than punting and kickoffs, with commentary on how improved FG kicking percentage is affecting fourth-down strategies.

Defining a "manager"


This triptych was the inspiration for the iconic alien "chestburster"


The triptych is "Three Studies for Figures at the Base of a Crucifixion" by Francis Bacon.  (No, not that Francis Bacon).

I learned this and other interesting tidbits about the chestburster scene from this video -

The Bluetooth logo is formed by Nordic runes


The logo combines "haglaz" (H) and "berkanan" (B), the initials of Harald "Bluetooth" Gormsson, King of Denmark and Norway.
Harald's nickname "Bluetooth" first documented appearance is in the Chronicon Roskildense from 1140.  The usual explanation is that Harald must have had a conspicuous bad tooth that has been "blue" (i.e. black, as "blue" meant dark).

Another explanation, is that he was called Thegn in England (corrupted to "tan" when the name came back into Old Norse) — in England, Thane meant chief. Since blue meant "dark", his nickname was really "dark chieftain".

A third theory, according to curator at the Royal Jelling Hans Ole Mathiesen, was that Harald went about clothed in blue. The blue color was in fact the most expensive, so by walking in blue Harald underlined his royal dignity.

Some "shower thoughts" about language

Anyone notice the irony behind "hyphenated" and "non-hyphenated"?

If a word describes itself, it is homological. If a word does not describe itself, it is heterological. So is heterological homological or heterological?

Hippopotomonstrosesquippedaliophobia is the fear of long words.

Monosyllabic isn't.

One word in the English language is always spelled incorrectly.

Every winter men give the finger to snowblowers

Since 2003, roughly 9,000 Americans have lost a finger (or two, or three) to a snowblower-related injury, according to estimates derived from Consumer Product Safety Commission data. Overall, about 15 percent of people who go to the E.R. as a result of a snowblower injury end up getting fingers amputated.
The year-to-year fluctuation in these numbers is probably related to the number of severe snow storms in the U.S.
Why are men losing their fingers? For the simple reason that they keep sticking their hands in snowblowers while they're still running.

Young blood reverses some age-related impairments

As reported in the prestigious Nature Medicine:
At the cognitive level, systemic administration of young blood plasma into aged mice improved age-related cognitive impairments in both contextual fear conditioning and spatial learning and memory... Our data indicate that exposure of aged mice to young blood late in life is capable of rejuvenating synaptic plasticity and improving cognitive function.
Discussed at a webpage of UC San Francisco:
Anatomically, it was clear that these mice formed more structural and functional connections between neurons, or nerve cells, while they also turned on more genes associated with the formation of new nerve connections.

Furthermore, the researchers found that a protein called Creb became more activated in the brain region known as the hippocampus, and that this increased activity was associated with the anatomical and cognitive improvements the team observed...

Identifying and getting rid of aging factors in old blood, or supplying youthful factors from young blood, might both be worthwhile strategies to combat aging...

Trees dead for 500 years - but not decayed


“We were gathering samples of dead trees to reconstruct summer temperatures in western Norway, when our dendrochronological dating showed the wood to be much older than expected”, says Terje Thun, an associate professor at the Norwegian University of Science and Technology’s (NTNU) Museum of Natural History and Archaeology...

Thun says that when a pine tree dies, it secretes a great deal of resin, which deters the microorganisms needed for decomposition. “Nevertheless, preventing the natural breakdown of the wood for centuries is quite a feat”, he says...
Resin was one of the ingredients used in Ancient Egypt for mummification, so its conservation abilities have been known for millennia. However, that trees could “self-mummify” in such a humid climate for centuries was new to the NTNU scientists.
“Many of the trunks we dated turned out to have seeded in the early 1200s, and had lived for more than 100 years at the time of the Black Death around 1350”, Thun says. “That means that the dead wood has ‘survived’ in nature for more than 800 years without breaking down.”
More at the link. The tree in the photo grew began growing in 1334, and died in 1513!

Rechargeable lithium batteries are dangerous as plane cargo because when packed in bulk they can ignite. "Shipments of rechargeable batteries on passenger planes are supposed to be limited to no more than a handful in one box...

Tens of thousands of the batteries may be packed into pallets or containers and loaded into the cargo holds of wide-body passenger planes.

Jamie Diamond, CEO of JPMorganChase, complains that the financial sector is facing crippling over-regulation. "In the old days," Dimon said, "you dealt with one regulator when you had an issue, maybe two. “Now it’s five or six. It makes it very difficult and very complicated. "You all should ask the question about how American that is. And how fair that is," he added. "And how complex that is for companies."  In other news, "JPMorgan Chase earned $4.9 billion in the fourth quarter of 2014, the company announced on Wednesday, down from a year ago, but capping what CEO Jamie Dimon called a record year for the biggest U.S. bank by assets."

An op-ed piece at Vice's Motherboard is entitled "The Most Anti-Science Congress in Recent History is Now in Session." "That explicit brand of denial is prominent in the party’s new Senate leadership.

Butterflies can change their spots


Every aspect of a butterfly has been shaped by evolutionary processes over the millenia to render the butterfly as perfectly adapted as possible to its favored environment.  The shape of the wings, the wing pattern, the color of the eggs - all are the result of billions of tiny changes.

Some butterfly wing patterns incorporate "eyespots" such as those seen in my photo of an Eyed Brown above.  It has been well understood that one of the purposes these spots serve is to confuse a predator, as shown by the wings of this Common Buckeye I found with multiple beak-shaped defects in the area of the eyespots:


The process is demonstrated in this video by researchers at Oregon State University.  Mantids are shown attacking the head/thorax of butterflies without prominent eyespots, but the wing margins of those with eyespots:


What is most interesting is that the butterflies are the same genus and species, differing only in seasonal appearance.  (data and discussion published here).  The implications are explained at The Scientist:
Prudic and her collaborator found that the dramatic eyespots on the wings of Bicyclus anynana individuals in the wet season were more effective at fooling mantid insects, the butterflies’ main predators during rainy times, than the more diffuse wing spots of the dry season forms, which are preyed upon mostly by birds. The researchers even found that pasting wet-season spots onto dry-season butterflies had the same effect. Conversly, dry-season patterns [less-prominent eyespots] served to conceal the butterflies better from birds in its eastern African woodland habitats. “Having the right type of eyespot in the right season allowed the butterflies to live long enough to lay eggs and have more offspring in the next generation,” Prudic said. “With the wrong eyespot at the wrong time, they were quickly annihilated by the mantids.”
Fascinating.
