Keep the communication

For a short time, we will graduate from school. Before we leave, we make a rule, no matter what happen, we must keep the communication. After all, we live with each other for three years; we are just like a family, even though we are from different place, but in the period of the three years, we look after each other, the relationship we can not off.


  As the matter of fact, we do not want to leave each other. But my dream will not come true. Standing on the life shore, and watching passed time, loneliness and helplessness. All in all, such as the beautiful bloom of fireworks, after all, in permanent silence. Now owned by, what is happening is not blooming is at this moment. The answer is no. I think I will never give up rs, give up runescape money. Perhaps you think that I am not telling the truth. But it is the word in my heart. It helps me face the difficult; I feel that I am growing up.  Life seems to be only continuity in leave and together. Each time at the time of the laughter tighter, it means that at the time of the farewell. A lot of people think so. But I do not believe. I will not leave cheap rs gold alone. We are a union. It looks like my sister. We have the same blood, and we can not leave any one. It always in my side at the right time, it not wastes of my time and money. I think it is the reason why a lot of people away it. It does not matter; buy runescape will not affect your life.  Remember the past time, we play the rs together, at the moment, we must separate from each other. I do not know when we have time play the rs together; after all we do not know what happened when we leave. But at the moment, we all have the runescape gold, we should not lose the confident. I think it will be filled with the wishing in the future. I hope that everything goes smoothly. As long as we have rs gold, we will meet each other in the game, I believe. Dear friends, if you have the same situation with us, you should make a rule, keep the communication. It is our dream. It is also the friendship.

Why are so many objects in space shaped like discs?

It's one of the most consistent patterns in the unviverse. What causes it?

Videos
  • Spinning discs are everywhere – just look at our solar system, the rings of Saturn, and all the spiral galaxies in the universe.
  • Spinning discs are the result of two things: The force of gravity and a phenomenon in physics called the conservation of angular momentum.
  • Gravity brings matter together; the closer the matter gets, the more it accelerates – much like an ice skater who spins faster and faster the closer their arms get to their body. Then, this spinning cloud collapses due to up and down and diagonal collisions that cancel each other out until the only motion they have in common is the spin – and voila: A flat disc.

Scientists study tattooed corpses, find pigment in lymph nodes

It turns out, that tattoo ink can travel throughout your body and settle in lymph nodes.

In the slightly macabre experiment to find out where tattoo ink travels to in the body, French and German researchers recently used synchrotron X-ray fluorescence in four "inked" human cadavers — as well as one without. The results of their 2017 study? Some of the tattoo ink apparently settled in lymph nodes.

As the authors explain in the study — they hail from Ludwig Maximilian University of Munich, the European Synchrotron Radiation Facility, and the German Federal Institute for Risk Assessment — it would have been unethical to test this on live animals since those creatures would not be able to give permission to be tattooed.

Because of the prevalence of tattoos these days, the researchers wanted to find out if the ink could be harmful in some way.

"The increasing prevalence of tattoos provoked safety concerns with respect to particle distribution and effects inside the human body," they write.

It works like this: Since lymph nodes filter lymph, which is the fluid that carries white blood cells throughout the body in an effort to fight infections that are encountered, that is where some of the ink particles collect.

Titanium dioxide appears to be the thing that travels. It's a white tattoo ink pigment that's mixed with other colors all the time to control shades.

The study's authors will keep working on this in the meantime.

“In future experiments we will also look into the pigment and heavy metal burden of other, more distant internal organs and tissues in order to track any possible bio-distribution of tattoo ink ingredients throughout the body. The outcome of these investigations not only will be helpful in the assessment of the health risks associated with tattooing but also in the judgment of other exposures such as, e.g., the entrance of TiO2 nanoparticles present in cosmetics at the site of damaged skin."

Do human beings have a magnetic sense? Biologists know other animals do. They think it helps creatures including bees, turtles and birds navigate through the world.
