A gif representing nuclear fusion and how it creates energy. 
[Click for more interesting science facts and gifs]

For those who don’t understand the GIF. It illustrates the Deuterium-Tritium fusion; a deuterium and tritium combine to form a helium-4. Most of the energy released is in the form of the high-energy neutron.
Nuclear fusion has the potential to generate power without the radioactive waste of nuclear fission (energy from splitting heavy atoms  into smaller atoms), but that depends on which atoms you decide to fuse. Hydrogen has three naturally occurring isotopes, sometimes denoted ¹H, ²H, and ³H. Deuterium (²H) - Tritium (³H) fusion (pictured above) appears to be the best and most effective way to produce energy. Atoms that have the same number of protons, but different numbers of neutrons are called isotopes (adding a proton makes a new element, but adding a neutron makes an isotope of the same atom). 
The three most stable isotopes of hydrogen: protium (no neutrons, just one proton, hence the name), deuterium (deuterium comes from the Greek word deuteros, which means “second”, this is in reference two the two particles, a proton and a neutron), and tritium (the name of this comes from the Greek word “tritos” meaning “third”, because guess what, it contains one proton and two neutrons). Here’s a diagram
Deuterium is abundant, it can be extracted from seawater, but tritium is a  radioactive isotope and must be either derived(bred) from lithium or obtained in the operation of the deuterium cycle. Tritium is also produced naturally in the upper atmosphere when cosmic rays strike nitrogen molecules in the air, but that’s extremely rare. It’s also a by product in reactors producing electricity (Fukushima Daiichi Nuclear Power Plant). Tritium is a low energy beta emitter (unable to penetrate the outer dead layer of human skin), it has a relatively long half life and short biological half life. It is not dangerous externally, however emissions from inhaled or ingested beta particle emitters pose a significant health risk.
During fusion (energy from combining light elements to form heavier ones), two atomic nuclei of the hydrogen isotopes deuterium and tritium must be brought so close together that they fuse in spite of the strongly repulsive electrostatic forces between the positively charged nuclei. So, in order to accomplish nuclear fusion, the two nuclei must first overcome the electric repulsion (coulomb barrier ) to get close enough for the attractive nuclear strong force (force that binds protons and neutrons together in atomic nuclei) to take over to fuse the particles. The D-T reaction is the easiest to bring about, it has the lowest energy requirement compared to energy release. The reaction products are helium-4 (the helium isotope) – also called the alpha particle, which carries 1/5 (3.5 MeV) of the total fusion energy in the form of kinetic energy, and a neutron, which carries 4/5 (14.1 MeV). Don’t be alarmed by the alpha particle, the particles are not dangerous in themselves, it is only because of the high speeds at which they are ejected from the nuclei that make them dangerous, but unlike beta or gamma radiation, they are stopped by a piece of paper.

I’ve seen someone commenting that Storm’s skin color used to be much lighter in the far past, and that left me wondering… Maybe the editions in Spain were recolored or something, but in my old comics she looks fairly dark skinned, so I wouldn’t say is a progression from lighter to darker through the years (though we can all agree that the color artists haven’t been consistent at all).

But I definitely like that the colorist in her present solo run is making her skin look more like Kenyan, for her mother was Kenyan and her father Afro-american, and Kenyan people and other Sub-Saharan ethnic groups are usually more dark-skinned than what she’s been depicted as in the past.

(sorry for the bad pictures, I can’t scan it).

15-Year-Old African Kid Tells Madonna To Go ‘Have Sex’ with Herself →

almightykushlord:

Dakarai Molokomme, a 15-year-old starving child from a small village in Zimbabwe, has just told , one of the most famous pop stars in the world, to  and f*** , the local media are reporting exclusively.

“Yes, it’s true, I told Madonna to go f*** herself. Do you want to know why?” Dakarai asked. “It’s the same thing every time with these snobby rich Americans. Every once in a while they come to show us their support for the so-called eradication of poverty by adopting a child from a starving family, but they actually do more harm than good. Transracial international adoptions are part of the white savior industrial complex,” Dakarai explained.

In further discussions with journalists from the media, the  stated that “none of the children here actually want to be taken away from their family and friends so they can be displayed as some kind of trophy in the homes of self-righteous singers or actors who want to score some points with the media and Oprah.”

“If they really want to help us, they should get Big Pharma to ship us some anti-retroviral drugs for the AIDS epidemic, or build schools and hospitals. If they don’t want to do that, then they can all go f** themselves!” the child told reporters.

The 15-year-old also stated that he would say the same thing to any one of those American or European “faux humanitarian posers”, except for Bono, whom he said he would also kick in the groin.

“Bono’s efforts to save the African savage from itself prove that the colonial imperative is alive and well,” Dakarai said as he walked with other village children collecting sticks to build a tree fort.

THIS IS THE RAWEST 15 YEAR OLD ALIVE

I saw this story circulating some years ago and I didn’t find a source back then, now I’ve tried to make a quick google search again and the first page of google results all lead back to tumblr, the only “source” I’ve found after a couple of minutes searching in forums is this same “article” in the global edition, which, surprise! it’s a satire page. All the articles are satire. 

"Theglobaledition.com is world’s most global news source. Information found on this website is so unique that it’s impossible to find it on any other website, unless someone copy-pastes it without our knowledge, in which case this sentence is totally unnecessary.

Sometimes we do use real events and names of people and/or institutions in our stories but only for satirical or parodical purposes. If you are one of them and you don’t want your public persona to be exposed to the public sense of humor, please let us know at editor (at) theglobaledition.com and we will do our best to ignore it.

We do our best not to provide you with factual and accurate information. If that by any chance happens, please let us know so we are able to correct the mistake and fire the author who allowed himself to think he is a journalist.”

So, fake story. Please tumblr, it only takes five minutes to source your information.

Ancient graffiti proves Spain’s Irish links

archaeologicalnews:

An ancient inscription discovered on a 14th century church in Spain’s Galicia region has been identified as Gaelic; the first written evidence of the northern region’s Irish and Scottish heritage.

For centuries it has gone unnoticed, weathered by Galicia’s incessant drizzle but still visible to those with an eagle-eye.

On one of the granite walls of Santiago church in the small town of Betanzos, a small previously unintelligible inscription five metres above ground kept historians and epigraphists, or people who study ancient inscriptions, baffled for decades.

Researchers working for a private association called the Gaelaico Project now believe they’ve finally deciphered what it reads: “An Ghaltacht” or “Gaelic-speaking area”. Read more.

I consider Beyoncé to be the incarnation of Ororo Munroe on our Earth, so when I draw Storm, you can be pretty sure that I’m actually drawing Beyoncé.

Storm #1 or "Why mmmagpie bitches about people fucking with the colors in comic panels"

Images on the left are original screenshots from the digital version of the comic. They’ve been cropped, and that’s it.  The images on the right belong to three users - links to the original posts are in the captions. 

Now…do you see what’s wrong with this picture? This is why I bitch about edits, and how they misrepresent the comics. Storm has pretty dark skin. If you hadn’t read the comics, and only seen the edits, you might be a bit taken aback by that fact. That’s a problem. In polite company, it’s generally agreed that lightening the skin of a person of color is a no-no. And, unfortunately, that’s what’s going on here.

I’m not claiming that these edits were made to lighten Storm’s skin. But they do lighten her skin. And that is something to take into consideration before posting an edit. Representation of women and minorities in comics is a huge issue, and it’s fucking amazing that Storm finally has her own solo title. It’s not amazing that her skin is being lightened because people seem to feel a need to add a #mine tag underneath somebody else’s artwork.

1980s X-men.

I’ve tried a new toned paper sketchbook and response from commissioners have been awesome. I manage to get all great x-men commissions out of it. Wish i had time to draw Magneto rogue and Cyclops though.

Storm and Wolverine are fore sell at sdcc . The rest have been spoken for. Safe travels everyone!
