19 APRIL 1971: MEET SALYUT-1, THE FIRST SPACE STATION!

This day (14 April) of 1971, the former Soviet Union (aka USSR aka CCCP) shoots into the sky a 20meter long, 4meter wide metal beast of more than 18 tons: the Salyut-1.
That’s the veeery first space station ever.
The Salyut-1 has three pressurized compartments for the crew. One of these chambers, the 7th of June, connects with the Soyuz 11 space ship which brings in the humans (aaand the space party begins).
The Homo sapiens exemplars keep spinning around in the sky for 22 days doing some science (ok, may be not a crazy space party after all...)
Then the crew goes back to the docked Soyuz 11, and gets back on Earth (suffering anyway of probably some kind of space hangover).
As for our dear space station, well, after 175 days in orbit (11th of October) it is made to plummet into the Pacific Ocean.
Farewell, Salyut-1, the veeery first space station ever.

VALENTINE'S DAY & THE BIRTH TIMING

Oooh hallo dear English hearing visitor, welcome back to me, @sciencemug, the blog/twitter account/podcast which speaks to you in Eng?ish a language that is to real English what the new Twitter timeline is to something someone really wants. Aaand that does it using the voice of a dumb human controlled via a wireless-voodoo trick. Aaaand that tells you mesmerizing science stories while, at the same time, is writing a manual about how to survive in case a pandemic of the “camomile virus”* ravage the world letting all the infected in a deep state of calm and serenity so that you suddenly find yourself in the dire situation of not having anymore anyone to fight with about how overrated and useless “Gravity” is aaaand also about your weird theory according to which “gluten free pasta” means that gluten -after corrupting pasta guards with an autographed picture of the juicy "Miss Tomato 2015" and some basil’s leaves- well, it, the gluten, manages to break free from the pasta prison and now lives, disguised as a protein bar for crossfit maniacs, in a minimarket in South Carolina.

Weeeel this time, dear listener, you’ll hear a 2011 story appeared on the journal Social Science & Medicine. The story's about how on Valentine’s Day [the phoniest, most artificial and trivial of all the fake festivities of the world (and that’s why the dumb human created a collection of love products right for the occasion and even wrote a love e-book!)] there’s a sensible increase of child births.


by sNg & @sciencemug

The story goes like that. Professor Becca R. Levy, Pil H. Chung and Martin D. Slade are scientist of the School of Public Health of Yale, and they think “cultural representations, in the form of salient holidays” (Levy et al, 2011 (P)) can influence birth timing. They in fact predict that, on Valentine’s Day, spontaneous, cesarean, and induced births would peak because this day is associated with positive feelings and events like “love, flowers” (P) and the rest of the cheesy stuff (and even if the researchers don’t mention it, well, chocolate too must be one huge deal in all this births story).
 

On the contrary, then, the Becca’s science-gang foresees a decrease in spontaneous and non spontaneous births on Halloween, ‘cause of the negative associations linked to this festivity (like witches, skeletons, death, ghosts, bad movies, not so bad movies, candy induced gain of weight, candy induced dentist bills and so on and on).
 

So the Becca’s trio digs into a specific dataset. This dataset is stuffed with all the birth-certificate informations of the United States in the week before and after Valentine’s Day and Halloween in the decade between 1996 and 2006 (as Becca&co explain in the paper, they stop in 2006 ‘cause “2006 [is] the most recent data year available from the National Center for Health Statistics at the time of [their] study in 2010” (P). 
And we’re talking of big numbers here as you can imagine dear listener: almost 1 million and 7 hundred thousands births during the Valentine’s Day window, and over 1 million and 8 hundred thousands births during the Halloween’s one.
 

Soo, what  do the scientists find?
The answer after the break. 
 


It’s Valentine’s Day and you are lonely and desperate for a date? Try “Chocotenin” the innovative product which formula is a mix of the most refined cacao seeds from Ivory Coast and the secretions of the back of the most toxic frogs of Mexico.

You’ll share the wellness that only munching chocolate can give you with what only bufotenin can offer, that is a wide range of vivid hallucinations among which, statistic says, you should also find a romantic one.
“Chocotenin”, and your Valentine’s Day will reach a whole new level of sadness!
(“Chocotenin” is also available in the form of candy bars for Halloween, eggs for Easter and whatever you want for whatever occasion/day you need it). 

 
So what do professor Becca’s and her science associates find out after checking the dataset of births in the US in correspondence of the two weeks centered on Valentine’s Day and Halloween from 1996 to 2006?
 

Weell, dear listener, the researchers find out that they are right, namely that on V-day, as respect to the week before and the one after it, births go up overall by 5%. More precisely the increase is of the 3.6% for spontaneous births, 12.1% for cesarean, and 3.4% for induced births.
 

As foreseen, besides, on Halloween the trend is

[Ham's pic is a Public Domain image adapted by @sciencemug (source: wikia.com)]

This day in 1961, chimp Ham's the first higher primate to go for a ride on a spacecraft.


So, let's go for a quick recap of what happens in space, in the first five months of 1961:


31-Jan-1961: Holloman Aero Med, Ham The Chimp (Pan troglodytes)

Altitude reached: 252,7km

[Post flight notes: Ham retires and lives at the Washington Zoo first (1963-1980), and then at the North Carolina Zoological Park in Asheboro (1980-1983). It now sleeps in front of the International Space Hall of Fame (Alamogordo, New Mexico)].


12-Apr-1961: Yuri Alekseyevich Gagarin (Homo sapiens)
                        (9-Mar-1934_27-Mar-1968)

Place of birth: Russia
Flight lenght: 108'
Top Speed: 27400km/h
Altitude reached: 327km


5-May-1961: Alan Shepard (Homo sapiens)

SAVE SANTA'S SHINBONE: THE HAPPY NEW YEAR POST! (PART2)

Ooooh hallo dear English speaking-thinking-reading visitor, welcome back to me @sciencemug, the blog that talks about science, the subterranean war penguins fight to overcome bunnies and become the new official Easter pets, and the pressing issue of carob addiction among the Santa’s reindeers.
Aaaand that does all of this in Eng?ish, a language that is to real English what Alien vs Predator was to a “non-commercial art driven only project”, “the soup of the day” to something one orders lightheartedly at the restaurant after having seen Fight club, aaaand homeopathy to something that actually work.

Sooo, there’re Dr. Donath and these five other scientists of the University of Basel who do an experiment to test the probability Santa Claus has to trip and fall and injury himself while doing his job on Xmas Eve.

The researchers recruit seventeen 20-40 years old, fit, healthy males for their experiment. A bunch of these guys is dressed up with Santa’s garb and handed up with a 20 kilograms [pick the joke about the metric-system AKA SI that you prefer and say it outloud three times in a row in front of a splintered mirror, then spit on your left hand and make a 180 degree turn on yourself… And realize that there’s no sense at all in it (I mean, I’m not talking of the SI, that’s absolutely rational and functional, no, I was referring to the things I mentioned after the SI)… Gee, are you always so gullible or is it just that there’s a sensible lack of oxygen in your brain since your stomach is sucking most of the blood given you’re still digesting all the food you've gulped down during the holidays?] heavy sack. This is the Santa Group (SG).  The other guys are in the Non Santa Group (NSG) and, as you can imagine, they dress normally and carry no sack.

All the volunteers take three tests, two to check their gait (a walk along a short path and a brief session on a treadmill), and one to monitor their sway (a short stand on a plate connected with sensors). The volunteers take all tests barefoot (in order to exclude anything that can alter their responses during the tests. Or, maybe, but it’s just a guess, ‘cause Donath et al’s initial idea, before it were sunk by the lack of funds, was to couple their experiment with that of a group of Lapp endocrinologists interested in determining the amount of sweat - and therefore the intensity of the stink - produced by Santa’s feet on Xmas Eve and to set, like that, the level of biohazard he represents for the children of the world exposed to high doses of his “residuals” on Xmas early morning SM’s Note).

Moreover, the Donath’s volunteers go for the tests both while focusing just on them, and while doing at the same time also a

I KNOW, I KNOW...

Reasons why the Xmas post part 2 is not ready yet:

- the wormhole near SM's url-house collapsed after it (the wormhole, not SM) ate too much pudding at its X-mas dinner and therefore all SM's connections with the part of the galaxy where its will went on holiday are gone and then it (SM, not the will or the wormhole) was (and still kinda is) screwed
- SM's armpits were terribly irritated by the deodorant it kept using in spite of its own warning and therefore it spent the last two weeks scratching itself
- there's been an electric storm a trolls' rumble a mean virus a servers' strike an invasion of pink grasshoppers a webshake a webquake a riot of nightmares with Lady Gaga wearing a normal dress a massive solar flare and, well, the news...
- PiPs ate it


(I guess that, at this point, it's out of question that you had on your list/you will fulfill a new year's resolution like "Put a couple of [your money] on SM's fund raising campaign", right? Yeah, I can't say you're unfair...)
