What sense make of tonight Paris attacks, if any?

Early stories told by victims who escaped some of the attacks we can hear on French news contain an indication of a motive: payback.

More specifically, payback via killing and terror as an act of war, perceived by them as legitimate following the armed involvement of France in Syria and against ISIS.
That's what they said.


With more than a hundred people killed and several simultaneous armed attacks against civilians, targeting symbolic places like the Stade de France (Football which is the most popular sport, symbol of victories and cultural unification) or the Bataclan (a small concert hall, symbol of culture, reputed for the magic intimacy artists find here with their audience) as much as people, this event still ongoing is the largest terrorist attack in France to date.


I can't tell if this justification by payback instead of mainly ideological really is significant.
After all, those who commit barbaric acts, leading to their own death have to justify them to themselves somehow.
It could be significant, differentiating then what happened tonight from Charlie Hebdo previous events.


In case it is significant, it is a reminder that France army is indeed at war in foreign countries and against multiple groups including Islamic ones.

Actually, France was close to go to war against Assad in Syria several years ago with the idea of saving civilians mass murdered by a dictator and help the democratic opposition to establish a legitimate replacement government.
It turned out that the situation wasn't quite so simple, and after failing to convince other countries to follow it didn't happen.

After that, France's army got involved in Mali, since January 2013.

Now, France has started bombing targets like ISIS training centers in Syria, since September 25 2015.


I can only observe that my country is not a neutral one.
Instead, it tends to enter armed conflicts when asked to by foreigners demanding help when crimes against humanity and mass killings happen.
I think it does with reasonably sincere goals to protect human rights more than plain political or economic self-interest. France has a tradition of action to protect human rights.
A majority or French people are against war however. They also learned their lessons from a colonial history on not trying to "civilize" other countries.


But France is still involved in wars.
And tonight's attacks might be one among many acts of the distant war happening in Syria French citizens do not really see or live until now.

What I hope is that the French government won't run into more paranoia. The ongoing direction for Internet surveillance is bad enough already.
I hope that the French government won't be trying at any cost to prevent new attacks by punishing the local population for the consequences of a war fought distantly.
Won't be trying to provide an impossible security at the cost of freedom and privacy.


I see that other European countries put more resources into welcoming refugees, less into armed conflicts.
Maybe it's a safer approach. Maybe it's a better one.

Still providing help to other human beings in need by making an effort to share a better environment, instead of leaving them trapped into the insanity of war or oppressive regimes.
But doing so in another way that getting involved in the same violence and insanity.
Because as we can see, through such interference we end up bringing the insanity back home at some point.


It's true welcoming refugees is not the easiest thing for everyone, but tonight events might be a reason to reconsider current France's approach to human rights protection and peace.

Lanugo is the first hair to be produced by the fetal hair follicles, and it usually appears on the fetus at about 5 months of gestation. Lanugo is very fine, soft, and usually unpigmented. Although lanugo is normally shed before birth, around 7 or 8 months of gestation, it is sometimes present at birth. This is not a cause for concern, lanugo disappears of its own accord within a few days or weeks.

However, if you’ve grown lanugo (as an adult) then you are in a state of severe malnutrition and emaciation. The growth of lanugo is one of the body’s ways of insulating itself. When an anorexic loses too much weight and no longer has enough body fat to help heat herself, the body takes over and grows lanugo. These hairs grow in thickly and attempt to trap heat that is lost from the body before it dissipates. Lanugo is almost like a blanket that the body grows itself.

Lanugo will not grow on all anorexics, but it is usually found on anorexics who have suffered from severe weight loss and are approaching emaciation.

Octopus Cares For Her Eggs For 53 Months, Then Dies
For many a female octopus, laying eggs marks the beginning of the end. She needs to cover them and defend them against would-be predators. She needs to gently waft currents over them so they get a constant supply of fresh, oxygenated water. And she does this continuously, never leaving and never eating.

Ferrofluids are liquids that become magnetized when a magnetic field is applied. They're made by suspending nanoparticles (particles only a few nanometers -- tens of atoms -- across) of magnetic materials, each coated with a substance that keeps it from clumping, in an organic solvent. When magnetized, they tend to form characteristic "hedgehog" shapes.

These were originally invented for rocket fuel: the idea was to mix these directly into liquid fuel, so that a magnetic field could pull them straight into the engine. That eliminates the mechanical pumps that are at the heart of liquid-fueled rockets, which (especially then) were the #1 source of problems. Today, they're used for all sorts of other applications: for example, they're used to create hermetic seals around rotating drive shafts, like the ones in your hard disk, since if you just magnetize the shaft a bit they'll stay in place even as things spin around. Using similar tricks, they're what keep the voice coils of your speaker cool.

Basically, you can find ferrofluids anywhere that it would be really useful to hold some liquid in a strange position as if by magic. 

And here is what happens if you take a screw, apply a magnetic field to it, and pour a ferrofluid down the top. It both lubricates the screw very precisely, and looks really neat.

You can learn more at http://en.wikipedia.org/wiki/Ferrofluid .

Here is something absolutely spectacular. When we look up at the night sky, we can see our own Milky Way Galaxy as this white fog like line all across it. It's a stunning sight. And we can also see distant stars, but we have no concept of other galaxies because their edges are not distinguishable by the human eye. They are not bright enough to be seen as a whole.

But what if we could see them? How big is our neighboring galaxy, Andromeda, really in our night sky? Below, is an image overlay of the night sky, with our moon, and the actual size of Andromeda. 

Isn't this amazing?

It's huge! And keep in mind that it's currently 2.5 million light years away. Here is another picture from NASA: http://apod.nasa.gov/apod/ap130801.html

But, of course, it's going to get even bigger. Andromeda is on a direct collision course with our Milky Way Galaxy, currently approaching at a speed of about 396,000 km/h, and it will slam into us in about 4 billion years (although there is no real risk of actual planets hitting each other). And after a short dance of another 1-2 billion years, we will merge into a new larger galaxy. Here is a simulation https://www.youtube.com/watch?v=4disyKG7XtU

Of course, this makes little difference to us here on Earth. You see, Earth won't be a habitable planet by then. Our own sun is dying, and will slowly turn Earth into a wasteland over the next 3 billion years. So by the time Andromeda hits us, we will no longer be here. 

Hopefully, we will have become a fully native spacefaring race by that time, with colonies on thousands of planets, as well as entire civilizations living in huge spaceships wandering the universe. http://goo.gl/iTBrr5

Goosebumping story about how important can CPR be. You could be the one with powers to bring a person back to life from death.
 
The abrupt end of this week's +All About Android

I realize I ended this week's episode with a rather sudden shift in tone and subject matter, and I mentioned not wanting to go into further detail as to why.

Truth be told, I'm still coming to terms with the experience, and every day, its getting easier to understand what happened, but what I realize is that there are only positive things that can come from sharing the story, especially because it has a happy ending. THANKFULLY.

 I didn't want to get into details during the show cause I didn't want to dilute the message, or misconstrue my reason for doing so.

But honestly, it weighs heavily on my heart, and I think writing about it might actually help me to move beyond it, and might actually encourage others to take action of their own if ever they are in a similar position.

Last weekend, I was at a pool party with lots of friends and families. Towards the end of the evening as it was getting dark, I decided to throw on some goggles and dive into the pool to see if I could swim from one side to the other while holding my breath. When I started underwater, I notice a dark form on the floor of the other side of the pool. Unsure what it was, but fearing it might be a person or child, I suddenly found myself swimming as fast as I could to investigate and sure enough it was the body of a little boy, my friends son.

Holding my breath underwater was never easier at that moment, I still hadn't come up for air. Adrenaline is a crazy thing. The boy was lying on the pool floor, face down, absolutely still and completely colorless. It was as if he was lying on your living room floor, but at the bottom of 4.5 feet of water. He had drowned. My reaction was to swim to him as quickly as possible and lift him out of the pool, which I did. This is a scene that has replayed in my mind countless times since then. It's kept me up at night and its brought me to tears.

My memory is somewhat splotchy but I remember coming up with his body and screaming "Help! Help! I need help!" over and over as loud as I could scream, at which time THANKFULLY his parents were there quickly, running over and pulling him from my arms.

I then recall his mom on top of him at the side of the pool doing chest compressions and counting up to 30, then pausing as his dad breathed into his son's mouth 2-3 times. At which time his mom began swiftly compressing his chest counting loudly to 30 as she did it, basically repeating the process. I learned about CPR prior to having our first child so the process wasn't foreign to me, but watching two people who REALLY knew what they were doing (he is in fitness, she is a nurse) was really powerful. Knowing that it was his parents made it even more so.

This went on for around 2-3 minutes, though my sense of time is warped. All I know is at some point, I eventually saw the boy twitch a few times ("he's moving! holy shit he's moving..."), move his arm, and finally vomit all over the pool while still lying on his back.

CPR continued until it was obvious that he was lucid and by this time, the ambulance had arrived. He was whisked away to the ER with his parents. My wife and I kept their 2 year old daughter with us to take care of her while they went to the hospital with their son.

Something to know about drowning is that simply reviving a person who has drowned does not in fact mean they are out of harms way. Secondary drowning is something that happens when water enters the lungs, like happens when someone is drowning, and restricted breathing as a result of that trapped water can take place anywhere between 1-24 hours after the incident. Risk is low (1-2%) but significant. He had considerable water in his lungs and pumping his lungs of water still resulted in about 10% of the water still in there that they couldn't pump out. He was monitored in the hospital for 48 hours to be safe.

He was also given a multitude of brain scans and tests and all tests came back positive. No brain damage, something that begins to set in after around 4-6 minutes of no oxygen to the brain.

We don't know how long he was in the water. Based on his skin color (grayish to blue) when I found him, and based on the tests and oxygen saturation in his body, the hospital expects he was likely in the pool for around 2-4 minutes. Meaning had I not gone into the pool when I did (a freaky, random decision on my part cause I NEVER swim laps thanks to a shoulder surgery years ago, and I also NEVER wear goggles cause I don't actually own any), he would likely be brain damaged at the very least, or worse yet, dead. We literally got to him, and revived him at the last possible moment.

We were lucky. So fucking lucky.This boy has been given a second chance at life. His parents were given a second chance at having a son.

CPR LITERALLY BROUGHT HIM BACK TO LIFE FROM DEATH.

Because of quick action on our parts, he is alive. On Monday while at work, I got a text message. I checked it and it was a photo of him in his hospital smock, smiling and playing. It hit me hard. That being two days after the incident. If anything had happened differently, I could instead be getting a text message with details of his funeral. Instead, I got a picture of him being a four year old kid, happy and healthy, and ALIVE.

This is why I didn't tell the story on the show. Please don't mistake this post for being a story about me and how I helped. This is not my story. This is about how knowing what to do in an emergency actually saves lives, and that's important stuff. If YOU know CPR, something that takes little time to learn.... YOU could be the one to bring someone back to life from death.

Can you even understand how powerful that is? You are literally a super hero. Magical powers. All that shit. Knowing this is the difference between life and death.

(deep breath) OK I feel better.

Corina Marinescu originally shared to BIODIVERSITY:
 
 How do dogs “see” with their noses?
Did you know that dogs smell in stereo? The ability to smell separately - with each nostril - helps them determine from what direction smells come. This is just one of the many ways that dogs’ wonderfully developed noses make them so scent-savvy.

Corina Marinescu originally shared to NATURAL PHENOMENA:
 
Upward lightning primarily occurs when there is a nearby positive cloud-to-ground flash. The electric field change caused by the preceding flash causes an upward positive leader to initiate from a tall object such as a building, tower or wind turbine. It is the shape of the tall object and the resulting enhancement in the electrical field that makes it possible for an upward leader to form following a nearby flash.
