The collision between the Milky Way Galaxy and the Andromeda Galaxy.
welp, looks like we pretty fucked.
facts about this: 1. it isn’t going to happen for a while
2. we are actually going to survive this and the sky will look amazing that night scientist have predicted
i wanna live to see this
^killer of dreams
what if you actually continue to think about things as you sleep, and that is what a dream is. What if sleep only exists to allow ourselves to think about only what we really, and truly want to think about? If that is the case then we have sequestered off an entire portion of our day to think only of what we want and created a separate, and completely safe place for us to do so. Humans.
What happened…when the object apparently responsible for the extinction of the dinosaurs hit the Earth 65 million years ago?
“First, there was a gigantic fireball brighter than the Sun as the comet plunged to its death, not with a whimper, but a bang. One casualty was the ozone layer, which temporarily vanished. Seconds after the big comet first encountered Earth’s upper atmosphere, it carved out a crater - now buried - 200 kilometers wide and 25 kilometers deep. All that debris shot up into the sky and came back again, all over the Earth. No place would have been spared a hit of at least a tiny particle.
Reacting to this incredible bombardment, the air temperature rose quickly until, for mor ethan two hours, the worldwide temperature reached that of an oven set to broiling. The sky glowed like an electric heater. Ground fires flared everywhere. Then the temperatures started to drop, and drop, and drop. A thick cloud of dust blackened the world, setting off a several-month period without sunlight. Rains poisoned with sulfuric and nitric acid added to the misery.
With blow after blow to the biosphere…most large land-roving dinosaurs probably died within weeks. Other creatures took longer; those who survived one disaster would perish in the next one. Slowly, the great cloud dissipated, and temperatures began to rise again, this time due to a greenhouse effect that lasted for centuries or millennia. Overall, perhaps 70 percent of all the species of life died during the siege, and in North America at least, about half of the species of flowering plants.
But not everybody. Some of the hardier representatives of many species, including the ones equipped to hibernate, made it through the impact winter. Enough small mammals survived that, when the biosphere finally started to recover, they began to proliferate and flourish.
Impacts clear the decks for new forms of life. The fossil record shows that after major impacts, there is a burst of speciation. New life forms fill the niches that the old ones leave behind. If there were no impacts, the thrust of evolution might have slowed down, and today there would be a different set of species inhabiting the Earth.”

“Have you ever noticed that the only metaphor we have in our public discourse for solving problems is to declare war on it? We have the war on crime, the war on cancer, the war on drugs. But did you ever notice that we have no war on homelessness? You know why? Because there’s no money in that problem. No money to be made off of the homeless. If you can find a solution to homelessness where the corporations and politicians can make a few million dollars each, you will see the streets of America begin to clear up pretty damn quick!”
Most of your body is younger than you are. The cells on the topmost layer of your skin are around two weeks old, and soon to die. Your oldest red blood cells are around four months old. Your liver’s cells will live for around 10 to 17 months old before being replaced. All across your organs, cells are being produced and destroyed. They have an expiry date.
This beautiful video showcasing the behaviour of magnetic putty is strangely soothing, which isn’t a bad thing right about now. Via Colossal.
What sort of witchcraft is this?? It sort of looks like a living thing, taking in another object as food. And at other points it reminds me of perhaps a heavy stone falling into the center of a large body… I would like to see this stuff on the ISS…

The reason I find this image so compelling is that, while today’s events had such an enormous impact on people across the globe, from Earth’s orbit there is no visible sign of any degree of distress. We are so small on the cosmic scale and yet that fact does not reduce the significance of an event such as this. We are so infinitesimal and yet that fails to lower the tragedy or render the people injured or murdered in Boston today superfluous. Every single one of us is a microcosm, striving in one way or another to understand the cosmos in which s/he resides.
You ask knee how my day is? Not too scabby, my friend!
Jon Stewart interviews George Carlin.
Nothing makes me as happy, yet so very sad when i find something either by, with, staring or about George Carlin that i have never seen before. I get ecstatic simply because i have another little bit of Georgie. Something from him that i have never, EVER seen before. A little more wisdom, a little more humor and a little more to think about. It gives me a brief moment of euphoria, i am hearing or seeing or reading something he has said or done or wrote, and it is new to me. It is opening up more parts of my mind, giving me new ways to look at things and fueling my fire for development. But thats what depresses me the most. I get that feeling of new, and that feeling of thought and learning and happiness and joy, and i dont know if i will ever get that from him again. I might not accidentally stumble upon another lost and forgotten interview, or some random guest star spot on a late night monkey drama. This might be the day that i have seen all that can and will ever be seen, heard all that can be heard and read all that can be read. He isnt making anymore, so he is a depleting source of energy. I look forward, and dread the next new Carlin i come across. And with that said, i give you a very VERY happy, yet horribly crippling moment for myself.
From Blind to not.
Charles Darwin discovered in 1859 that over a series of generations, a species overcomes minuscule physical changes which improve the overall functionality of that species. Evolution, also known as natural selection, is now a widely excepted theory that helps to explain why we are the way we are and where we came from.
However, even with the hard proof provided by not only Darwin, but the fossil record itself, still some people today shrug off evolution as bunk and refuse to think of it as a possibility.
The eye, a complex and seemingly perfect organ, is said by many to be a little “too perfect” to have just happened by happenstance. Even Darwin himself commented on the fact that “it was impossible to imagine that [the eye] could evolve by gradual degrees”.
With the eye existing in many different forms through out the animal kingdom, almost in different evolutionary steps, we can begin to understand how it is the eye formed to become the spectacular tool it is today.

New see-through brain photography clarifies how connections between neurons look and act. Using a Hydrogel, researches were able to remove all the fats and lipids from the brain of a mouse. These fats and lipids surround the cells of the brain (and all organs for that matter) and impede the direct view of a neuron. However, just removing the fats and lipids would cause a total collapse of the organ for there would be nothing left to structure the thing. That is where the Hydrogel, called CLARITY, comes in. It replaces the fats and act as a structure for the neurons, allowing for the first time ever a completely invisible and intact mousy brain!
Once you have a completely clear and transparent brain, what do you do now? Its not like you can see invisible things, so how can you study something you cannot even see? You guessed it! Molecular Markers!!!
Okay… so maybe you didnt guess it.
Never the less, CLARITY, being rigid enough to act as structure and support the organ, is still permeable to molecules. This allows scientist and researchers to find and flag interesting features and key parts to an organs system.
Each little dot of color you see here is a Molecular Marker placed in the brain and each different color marks a separate neural cell; Excitatory Neurons in green, Inhibitory Neurons in red and and cells called Astrocites are blue.
CLARITY isn’t a technique to work specifically on just mice, but can also work on the Human brain. CLARITY may finally be able to allow researchers and scientists to discover the relations between thought and neural connections.
