THE FIVE SECOND RULE – RICH PASCHALL

A few curious thoughts by Rich Paschall, Sunday Night Blog


Admit it!  You have probably invoked the five second rule many times in your life.  Maybe you tend to do it when no one else is around, but you do it nonetheless.  No matter what some in society may say, you can not help yourself.  You may think it just a little bit evil, but you do it anyway.  You may even do it openly, not caring what others may think.  Don’t worry.  They do it too.

In case you are one of the few who have not heard about it and have not followed the widely disputed practice, the “Five Second Rule” is the belief that if you drop some food on the floor, it is alright to eat if you pick it up right away, say in five seconds.  While common sense may speak against such a practice, some science seems to be coming down in favor of what once was folklore or an “old wives’ tale.”  A recent study seems to suggest that a few seconds on the floor does not matter much.  Your wet gummy bears are not likely to pick up much in the way of bacteria if you pick them up right away.the special

Unbelievably, dropping food on your carpet seems to pick up less bacteria than dropping it on your tile or linoleum floor.  Of course, if you own a dog or a cat, the food item may pick up some animal hair or dander you might not want to pop in your mouth.

No matter how clean Fido looks to you, all that rolling around on the floor is not good for your dropped food.  Also, you have to consider that Fido might beat you to the item, in which case your dog has the treat you lost and let’s face it.  Your dog never seems to get sick after eating food off the floor.

While I would not care to eat off my floors, considering what I know, I may be less reluctant elsewhere.  You may have heard that Aunt Matilda’s house was so clean you could eat off the floors.  That may literally be true, although I do not think I would try that on a dare.  She might slap me.  Still, it is good to know that your odds of puking later are greatly diminished according to modern-day science, if your food is not down there too long.

Who funds this type of study, you may wonder?  Who cares?  This particular science is extremely important when you consider the amount of people who drop food on the floor, then pop it in their mouths.  Isn’t it time we got the answer to the age-old question, “Does the five second rule really exist?”  Now we know (perhaps).  There are, of course, studies that say the exact opposite (see link below).  We will ignore them for now.

Life itself also has a rule like the Five Second Rule.  It goes like this. The longer you are down, the more likely you are to pick up dirt.  When you fall down, get knocked down, get tripped up or whatever it is that causes you to land on your butt or your face, it is best if you get right back up and get going.  The world just does not look as good when you have fallen to the floor.

No scientific study is needed here.  Hopefully common sense will tell you. The quicker you get up and clean yourself off the better it is for you.  If it has been a particularly bad day, it can be hard to convince yourself to get off the ground.  You may wish to wallow in whatever is down there.  Just like the food in the study, more is likely to jump on you if you stay put.  It is the nature of life.

There is one more thing to consider while we are invoking scientific studies.  It is a known fact that if you fall and stay down, you will look like a dropped treat to people-eating Cyclops.  In that case one of them is likely to scoop you up and pop you in his mouth.  Another thing to know from the most recent study is that Cyclops have a much longer time, a 5 day rule perhaps.  In that case, wallowing in the muck with one of Fido’s playmates is likely to do you in.  Being chomped on by Cyclops is far worse than eating candy off the floor.  You have been warned.

TACHYON WAVES, WARP DRIVES, AND A TOASTER OVEN

Garry and I binge watched the entire “Star Trek: Next Generation.” On Netflix. We had missed the show’s initial run. 1987 through 1994 were busy years full of work, moving houses, digging into careers. Getting married. Moving again. Watching TV wasn’t a priority back then.

BBC America showed the series last year, but not in order. When Netflix gave us the opportunity to catch up, we did, viewing two, three, four episodes each night.

There’s a lot of tech talk on the Enterprise. No problem. Pass the warp drive. I’ll have a side of tachyon particles. I understand their science as well as I understand anything. Which is to say, not at all. I understand the engines on the Enterprise as well as I understand my toaster oven.

Tachyon energy is crucial to all kinds of weaponry and fuel. They are part of what powers the warp engines on the Enterprise. The warp engines are what lets the Enterprise be the Enterprise, travel at speeds faster than light … fast enough to explore the universe. Slither through wormholes. Travel through time.

For your information, a tachyon particle moves faster than light. The complementary particle types are luxon (particles which move at the speed of light) and bradyon (particles which move slower than light). If you live in the Star Trek universe, tachyon particles are as common as dirt. Or electricity.

enterprise next gen

Effectively, life and everything in it is a giant mystery to me, yet I feel as if I understand it. When they talk about it, I nod because I get it. I’ve been listening to this mumbo jumbo for so many years, it has achieved a pseudo-reality. Because when I look closely, there’s nothing there. I understand the technology of the 24th century exactly as well (and as much) as I understand the technology of the 21st.

How many of you know how the stuff you use works? Some of you do, but most of us know how to use our devices and gadgets, but have no idea why or how it works. I know how software is designed, how code is written and compiled. I used to know a little coding. In the end, though, I have no idea why code does anything. Why, when you compile a program, does it work? It’s just text. Why does it do what it does?

Why does anything work? Tachyon particles, warp drives, internal combustion engines, electricity, cell phones, WiFi. It’s all the same.

Magic.

And now, back to the Enterprise, already in progress.

THEY’RE BACK! RETURN OF THE GYPSY MOTH

It’s going to be a big year for the gypsy moths. They never really leave, but some years are really bad compared to other, relatively light years.

gypsy-moth-caterpillar

This is going to be a bad year. One side of my house is covered with caterpillars. Garry had to dig his car out, as if from under snow. They’ve been coming into the house via the dogs. A few hitched a ride on some Amazon deliveries. I’m spooky about bugs of any kind though I’m not actually afraid of caterpillars, per se.

Unlike spiders and other crawling insects, my heart does not threaten to seize in my chest when I find one. Unfortunately, my startle reflex doesn’t know what’s crawling on me. I only feel something crawling and I do the knee jerk EEK, YOW, UGH, YUK before I ultimately recognize the culprit.

It’s not only that the gypsy moths are creepy pests. They are an invasive pest that consumes oak trees. They have been known to wipe out entire hardwood forests. They’ve almost killed off the black oaks in Pennsylvania.

They aren’t even pretty. No redeeming features that I know of and no natural enemies, either. A pest of the first magnitude with the distinction of being number 1 on our national list of destructive invasive species.

As you’ve probably guessed by the repetition of the word “invasive,” gypsy moths are not native to these parts. Originally a European pest, they took to the New World with a vengeance as soon as they got a bite of it. They’ve been in New England since 1869. at which time they were accidentally introduced near Boston, Massachusetts. Normally, we are happy to have visitors to our fair shores, but not these guys.

In their 150 years on these shores, they have made their way from Massachusetts to Canada,  down to Florida, then back up the middle to Wisconsin and beyond. It’s only a matter of time before they are literally everywhere there is food they can eat. They prefer hardwood trees, but in a pinch, will eat literally anything that grows.

On a purely person level, this means that I won’t go outside unless I must until the moths retreat. We haven’t had a really bad gypsy moth invasion in a few seasons. Probably the exceptionally cold, snowy winters kept them in check.

They are back. I’m so very sorry to see them again.


NOTES:

1: In case you’re interested, click on “gypsy moths” here or at the beginning of this post. It will take you to a link where you can find out more than you ever wanted to know about these nasty, hungry pests. Yuck.

2: Don’t forget the ants. Just because caterpillars have arrived, it does not imply the ants have departed. Have I mentioned how much I hate the bugs? This is not going to be my favorite summer.

3: Sometimes, life in the country is way overrated.

TECHNICOLOR DREAMS AND GENETIC NIGHTMARES – BY TOM CURLEY

A few weeks ago my old friend Ben Taylor sent me a very interesting link to a story about archiving technologies . The story was about how all of our storage media eventually degrades. Film, tape, CDs, DVDs, flash drives, and so on all decay over time. Technicolor, the company that makes films so, technically colorful, has figured out a way to encode and store media on a DNA molecule! Here’s the article.

Basically, it’s not complicated. All of our media is now digital, encoded as a really long string of ones and zeros. DNA is a double helix molecule made up of four proteins CGAT. Cytosine, guanine, adenine and thymine.

They can combine in an infinite number of combinations, which is why DNA is such a handy way to store all of life’s genetic information. We also have machines called genetic sequencers that can both read a DNA molecule and build one.

DNA-O-MATIC! web.uri.edu

So, what the TECHNICOLOR people did was figure out how to encode the ones and zeros onto a DNA molecule, then build that DNA molecule. How do you play back the material? Build a player that reads the DNA molecule and converts it back to ones and zeros. Burn it onto a DVD and put it into your Blue Ray player.

The cool part is that you can store over 700 terabytes of information on one DNA molecule! Which is pretty much every movie and TV show ever made. The other reason they did this was because they say the DNA molecule is stable and won’t degrade.

But here’s the problem.

DNA MUTATES!!!!!!!

rbssbiology11ilos.wikispaces.com

That’s how evolution works!

If DNA didn’t mutate, we’d still be four-legged lungfish crawling up out of the surf, looking up at the sky, land and saying: “Well, this is different. Hey Phil! Come on up here. You gotta see this!”

Now at this point you could argue that DNA usually mutates when cells reproduce.  Sometimes the DNA copies aren’t perfect and that’s what causes the mutation. But the Technicolor DNA molecules are just sitting in a test tube. They are not replicating.

Technicolor-DNA-Archive-2

That’s true. However — there are other things that can make DNA mutate, like radiation. A stray alpha, beta, or gamma particle could come along, hit the molecule, and knock out a quinine here, a cytosine there. After a while, things could change. Not immediately, but after a hundred, five hundred, or a thousand years?

A thousand years from now a group of historians, anthropologists, archaeologists and movie critics could get together to examine a recently discovered cache of late 20th Century movies and TV shows. They were  found buried in a vault archived with a quaint technology utilizing DNA by a long-forgotten company called Technicolor.

HEAD SCIENTIST: As you all know the discovery of this cache of ancient media has given us an unprecedented opportunity to measure the accuracy of our historical records against actual recordings of history.  You’ve all had a month to watch and review media from the last millennium. What have you found?

SCIENTIST #1: Well, actually some their movies are quite good.  I just watched two fantastic movies, “Ishtar” and “Waterworld”.

HEAD SCIENTIST: Hmmm. Our records indicate they were two of the worst movies ever made.

SCIENTIST #1: I can’t understand why. Did you know that Ishtar was the movie where Betty Davis said “Fasten your seat belts, it’s going to be a bumpy night.!”  It only makes sense since they were all riding camels.  And Waterworld!  At the end, when Kevin Costner helped ET get back to his spaceship? I have to admit, I cried.

HEAD SCIENTIST: I see.  What about “Star Wars’?

SCIENTIST #2: I saw the first three movies starting with “The Phantom Menace”.

HEAD SCIENTIST: And?

SCIENTIST #2: They were really good!  And funny! Casting Groucho Marx as Obi Wan Kenobi and Robin Williams as  young Anakin Skywalker was inspired!

HEAD SCIENTIST: And the next three in the series?

SCIENTIST #3: Not so much. Darth Vader and the Emperor win in the end and destroy the rebellion. It was really depressing.  The only rebel left alive was Jar Jar Binks.

HEAD SCIENTIST: What about “Citizen Kane”? Our records show that as being one of the greatest movies of all time.

SCIENTIST #4: I don’t know why sir. In the first place somebody named Jackie Chan played the part of Kane. He spent the whole movie kicking people and riding on a sled. But he did do his own stunts!

HEAD SCIENTIST: What about “Casablanca?”

SCIENTIST #5: Horrible! Ronald Reagan as Rick and Joan Rivers as Ilsa? What were they thinking? No chemistry!

HEAD SCIENTIST: OK, what about television?

SCIENTIST #6: Quite frankly only one show stood out and it was brilliant.

HEAD SCIENTIST: What was it?

SCIENTIST #6: “Gilligan’s Island.”  Orson Welles as the Skipper, Brad Pitt as Gilligan, Marilyn Monroe as Ginger,  Sally Field as Mary Ann, Helen Mirren and John Barrymore as the Howells and  John Wayne as the professor.! Brilliant casting. And who knew Arthur Miller could write comedy!

KHANATE OF THE GOLDEN HORDE AND ME

map of mongol invasion paths

A little more than a year ago, I got to thinking about blood type. I wondered how come I have a B+ blood while everyone in my family is type O or A. Every time I’m asked my blood type and I say “B positive,” the doctor looks askance and says “We’ll just double-check that.” Because I shouldn’t have that blood type … but I do.

I decided to do a little research. See if I could learn something about where I come from using this tidbit.

Blood type O: the Americas

Blood type O: the Americas

It turns out, B-type people are universally less common than O and A.

I discovered that there is a high probability I have some Asian — Siberian, Mongolian, Chinese, Indian — ancestor. Genghis Khan made serious inroads into Europe and I am probably proof of it.

The incidence of type B is low amongst Jews (my folks). Low everywhere. It’s not unheard of, nor so infrequent as to be considered rare, but it’s not common.

Among native peoples in the western hemisphere, type O is basically 100%. Many scientists theorize “O” as the “original” human blood type with all other types having mutated from it.

That’s one theory, anyhow.

map golden horde

This is a bit of a hot topic because in a few places, notably Japan, blood typing has been used to categorize people as inferior,

There are always racists looking for a way to prove they are superior to everyone else. At least one group claims people of B type blood are descendants of Neanderthals while O and A are descended from Cro-Magnon. This is pure speculation based on not a particle of research.

Worse, there are pockets of racists who contend that A is the only pure Aryan blood type. On what evidence did they base this?

None. Nada. Nothing. Zero. No proof of any kind. They probably decided this because Aryan starts with an A.

Overall in the world, B is the rarest ABO blood allele. Only 16% of humanity has it. It reaches its highest frequency in Central Asia and Northern India. 

B is not a dominant blood type anyplace. It is most common in the Philippines and Siberia, lowest in the Americas. Exceedingly rare in the British Isles and Scandinavia. The highest percentage it reaches is 38% of the population in the Philippines. The middle East is more or less evenly divided into all three major blood types. If this shows some kind of migratory pattern for our ancestors, no one can prove it.

It turns out there is no universally accepted theory of the origins of man. Scientists and other theorists can’t even agree on whether or not we have the same progenitors.

blood types around the world

So after all this, I don’t know (for sure) more than I did when I started. Yet there is something to be learned from the distribution of blood types in the world. Unfortunately, no one is sure exactly what.

Mongols_Warriors06_full

So, did you learn anything?

I did learn a bit about blood types and inheritance in the course of this. My mother was O+ and by father A+ … so … where do I come from? The answer is that no matter what they say on television, it’s not that simple. There are at least 25 sub-types of blood, recessive genes … and mutations. The possibilities are literally, endless. So, when all is said and done, if you look like your parents, they’re your parents.

It’s also possible my blood type shows somewhere in my dim, distant ancestral history, a soldier from the Golden Horde left his DNA behind. I’m sure there is a story there.

I wish I knew more. So romantic.

ENDING POLIO – HAPPY BIRTHDAY JONAS SALK

For reasons that completely elude me, quite a few people are rejecting vaccination. They have somehow rationalized away some of the most important progress in human history. The result has been the reappearance of diseases we conquered, of which we thought we’d seen the last.

I remember the annual terror the summertime brought before polio vaccines made the world a safe place to be a kid.

anti-vaccine-cartoon

I remember lining up in school — a first grader — with all the other kids to get my shot and how happy our parents were that finally, we didn’t live under the terrible shadow of polio.

Here’s a reminder of how things were before there was such a thing as a polio vaccination, when summer was filled with fear for every child, everywhere.


Today would be Jonas Salk’s 101st birthday. Conquering polio was not only about Dr. Salk, though he was first at the starting line. As polio ravaged patients worldwide, two gifted American researchers developed distinct vaccines against it. Then the question was: Which one to use?

By Gilbert King – Smithsonian.com – April 3, 2012


They were two young Jewish men who grew up just a few years apart in the New York area during the Great Depression. Though both were both drawn to the study of medicine and did not know each other at the time, their names would be linked in a heroic struggle that played out on the front pages of newspapers around the world.

In the end, both Albert Sabin and Jonas Salk could rightfully claim credit for one of humanity’s greatest accomplishments—the near-eradication of polio in the 20th century. And yet debate still echoes over whose method is best suited for the mass vaccination needed to finish the job: Salk’s injected, dead-virus vaccine or Sabin’s oral, live-virus version.

In the first half of the 20th century, Americans lived in fear of the incurable paralytic poliomyelitis (polio) disease, which they barely understood and knew not how to contain. That the disease led to some kind of infection in the central nervous system that crippled so many children, and even a president (Franklin D. Roosevelt) was alarming enough.

Polio-salk-vaccine newspaper

But the psychological trauma that followed a neighborhood outbreak resonated. Under the mistaken belief that poor sanitary conditions during the “polio season” of summer increased exposure to the virus, people resorted to measures that had been used to combat the spread of influenza or the plague. Areas were quarantined, schools and movie theaters were closed, windows were sealed shut in the heat of summer, public swimming pools were abandoned, and draft inductions were suspended.

Just about 100 years ago, in 1916, polio rampaged through the U.S.

Just about 100 years ago, in 1916, polio rampaged through the U.S.

Worse, many hospitals refused to admit patients who were believed to have contracted polio, and the afflicted were forced to rely on home care by doctors and nurses who could do little more than fit children for braces and crutches. In its early stages, polio paralyzed some patients’ chest muscles; if they were fortunate, they would be placed in an “iron lung,” a tank respirator with vacuum pumps pressurized to pull air in and out of the lungs. The iron lungs saved lives, but became an intimidating visual reminder of polio’s often devastating effects.

HUNTING DINOSAURS

spinosaurus-1

On the evening of March 3, 2013, a young paleontologist named Nizar Ibrahim was sitting in a street-front café in Erfoud, Morocco, watching the daylight fade and feeling his hopes fade with it. Along with two colleagues, Ibrahim had come to Erfoud three days earlier to track down a man who could solve a mystery that had obsessed Ibrahim since he was a child. The man Ibrahim was looking for was a fouilleur — a local fossil hunter who sells his wares to shops and dealers.

Among the most valued of the finds are dinosaur bones from the Kem Kem beds, a 150-mile-long escarpment harboring deposits dating from the middle of the Cretaceous period, 100 to 94 million years ago.

After searching for days among the excavation sites near the village of El Begaa, the three scientists had resorted to wandering the streets of the town in hopes of running into the man. Finally, weary and depressed, they had retired to a café to drink mint tea and commiserate. “Everything I’d dreamed of seemed to be draining away,” Ibrahim remembers.

Ibrahim’s dreams were inextricably entangled with those of another paleontologist who had ventured into the desert a century earlier. Between 1910 and 1914 Ernst Freiherr Stromer von Reichenbach, a Bavarian aristocrat, and his team made several lengthy expeditions into the Egyptian Sahara, at the eastern edge of the ancient riverine system of which the Kem Kem forms the western boundary.

Despite illness, desert hardships, and the gathering upheaval of World War I, Stromer found some 45 different taxa of dinosaurs, crocodiles, turtles, and fish. Among his finds were two partial skeletons of a remarkable new dinosaur, a gigantic predator with yard-long jaws bristling with interlocking conical teeth. Its most extraordinary feature, however, was the six-foot sail-like structure that it sported on its back, supported by distinctive struts, or spines. Stromer named the animal Spinosaurus aegyptiacus.

Stromer’s discoveries, prominently displayed in the Bavarian State Collection for Paleontology and Geology in central Munich, made him famous. During World War II he tried desperately to have his collection removed from Munich, out of range of Allied bombers.

But the museum director, an ardent Nazi who disliked Stromer for his outspoken criticism of the Nazi regime, refused. In April 1944 the museum and nearly all of Stromer’s fossils were destroyed in an Allied air raid. All that was left of Spinosaurus were field notes, drawings, and sepia-toned photographs. Stromer’s name gradually faded from the academic literature.

I’ve always been fascinated by dinosaurs. This is a fantastic find. I thought maybe you would find it fascinating too.
