Science is awesome #science
There’s little we can add to what’s said or shown in this video by Fundación ANAR, or Aid to Children and Adolescents at Risk, to get across the impact and necessity of this type of campaign to help those who might be too scared to ask for it. With the help of the advertising agency Grey…
Mapping a Living Brain, Neuron by Neuron
A brain, along with all of the thoughts, decisions and consciousness that it brings with it, is nothing more than the sum of its parts. But it is precisely the sum of those parts that makes a brain more than just a pile of neurons and gray goo. Mapping the complex networks of the brain in space and time will be the key to figuring out how it works.
Thanks to some breakthrough work in a fish, we may be getting closer. HHMI scientists have mapped the activity of a zebrafish brain down to the individual neuron in real time! A zebrafish brain contains 100,000 times fewer neurons than our own, but techniques like this will make the Obama administration’s ambitious (and slightly controversial) human Brain Activity Map Project possible. Of course, mapping the activity of a brain isn’t the same as knowing what that activity means, but it’s hard to navigate anything without a detailed map. And when it comes to the brain, a static map is pretty useless. Seeing how signals change over time at a single-cell level is what it will take to turn flashing cells into an idea of what makes the brain tick.
This isn’t our first glance at what “fish thoughts” look like, but it’s definitely the most complete, and the most completely awesome. Check out more great coverage, plus complete videos of the blinking brain, at io9.
I really want to know what this zebrafish was thinking about that made its whole brain light up. Maybe “Oh man, I’m gonna be so famous on the internet after this!!”
The Science of Cats
The guys at AsapSCIENCE take aim at the internet’s favorite animal/purpose for its existence: Cats.
You’ll never believe what a cat is doing when it sticks its tail up and rubs along your leg. Smelly little weirdos.
“I notice they forgot to cover the science of why dogs are so much cooler,” said the science blogger who was clearly trying to raise a ruckus by starting a cats vs. dogs battle after the video he posted.
Kayaking Across an Active Volcano
By Alexandre Socci ”As a water photographer myself I was trying to get into the water but it was impossible, the water was about 90 degrees Celsius and there were lots of lava particles floating that could burn anything in seconds… even the kayaks came out of the water with some ‘scars’ from the floating lava!!!”
What a hardass #killingit
This five-frame sequence of images from NASA’s New Horizons mission captures the giant plume from Io’s Tvashtar volcano. Snapped by the probe’s Long Range Reconnaissance Imager (LORRI) as the spacecraft flew past Jupiter in 2007, this first-ever movie of an Io plume clearly shows motion in the cloud of volcanic debris, which extends 330 km (205 miles) above the moon’s surface. Only the upper part of the plume is visible from this vantage point.
That’s a huge volcano!
