I choose to portray myself as an anonymous entity because I believe that it prevents any distractions from the arguments I make, the concepts I debunk, and the ideas I propagate. All you need to know about me is that I support the progression of the human race to help build a better world.I enact this by assisting in the propagation of good ideas, and the destruction of bad ones.

Imagine how tough, resourceful, and lucky all of our ancestors must have been to survive long enough to pass on the message of life to the next, and the next, and the next generation hundreds of millions of times before it came to us.
There were so many rivers to cross, so many hazards along the way. Predators, starvation, disease, miscalculations, long winters, drought, flood, and violence. Not to mention the occasional upheavals that erupted from within our planet, and the apocalyptic bolts that come from the blue.
No matter where we hail from, or who our parents were, we are descendants of hearty survivors of unimaginable catastrophes. Each of us is a runner in the longest, most dangerous relay race there ever was, and at this moment we hold the baton in our hands. By Neil deGrasse Tyson (via ericwimberly)

As Virginia Hughes noted in a recent piece for National Geographic’s Phenomena blog, the most common depiction of a synapse (that communicating junction between two neurons) is pretty simple:

Signal molecules leave one neuron from that bulby thing, float across a gap, and are picked up by receptors on the other neuron. In this way, information is transmitted from cell to cell … and thinking is possible.

But thanks to a bunch of German scientists - we now have a much more complete and accurate picture. They’ve created the first scientifically accurate 3D model of a synaptic bouton (that bulby bit) complete with every protein and cytoskeletal element.

This effort has been made possible only by a collaboration of specialists in electron microscopy, super-resolution light microscopy (STED), mass spectrometry, and quantitative biochemistry.

says the press release. The model reveals a whole world of neuroscience waiting to be explored. Exciting stuff!

You can access the full video of their 3D model here.

How Big Is The Brain? Here’s Some Perspective.

Chris Whittaker and Laura White of Ashfield Healthcare Communications, and Craig Armstrong of CreativeFusion used a metaphor approach that put them in first place. They scaled the human brain all the way up to the scale of the world and described the size the structures of the brain would be at that size. This brings the tiniest brain structures into a scale we can all relate to. This approach combined with a crisp, clean style, does a great job of clearly explaining the scale of the human brain.

Some of the runners up are pretty impressive, too.

The bomb is dropped

The kittens sort of soften the blow.

this is the shittiest post ever. please unfollow me if you agree with this post also shame on OP for using cute kittens for this garbage post

not sure what it is exactly that makes this post so shitty? Because it’s promoting actual equality? instead of saying that you can call everyone else shit because you are part of an oppressed party you can say you are equal to them doesn’t exactly sound like a shitty idea to me.

BOOM. So many people on this website need to read this twice, let it sink in and then read it again.

Researchers successfully eliminate HIV virus from cultured human cells

The HIV-1 virus has proved to be tenacious, inserting its genome permanently into its victims’ DNA, forcing patients to take a lifelong drug regimen to control the virus and prevent a fresh attack. Now, a team of Temple University School of Medicine researchers has designed a way to snip out the integrated HIV-1 genes for good.

 ”This is one important step on the path toward a permanent cure for AIDS,” said Kamel Khalili, PhD, Professor and Chair of the Department of Neuroscience at Temple. Dr. Khalili and his colleague, Wenhui Hu, MD, PhD, Associate Professor of Neuroscience at Temple, led the work which marks the first successful attempt to eliminate latent HIV-1 virus from human cells. “It’s an exciting discovery, but it’s not yet ready to go into the clinic. It’s a proof of concept that we’re moving in the right direction,” added Dr. Khalili, who is also Director of the Center for Neurovirology and Director of the Comprehensive NeuroAIDS Center at Temple.
