Incredible and rare micrograph of a synapse 
Neuron cell body (purple) with numerous synapses (blue) magnified 80,000x under a scanning electron microscope.Everone talks about synapses even though some seem to use it to sound cool without actually knowing what it is. So for those persons (and everyone willing to become a bit more educated), here’s a simple explanation.Information from one neuron flows to another neuron across a synapse. The synapse contains a small gap separating neurons. The synapse consists of:a presynaptic ending that contains neurotransmitters, mitochondria and other cell organelles,a postsynaptic ending that contains receptor sites for neurotransmitters,a synaptic cleft or space between the presynaptic and postsynaptic endings.At the synaptic terminal (the presynaptic ending), an electrical impulse will trigger the migration of vesicles containing neurotransmitters toward the presynaptic membrane. The vesicle membrane will fuse with the presynaptic membrane releasing the neurotransmitters into the synaptic cleft.

Slow Light

It takes a photon just eight minutes to traverse the 150 million kilometres between the Earth and the Sun, but a photon in the core of the Sun will travel only thirteen centimetres in that same time.

Stars are essentially huge nuclear fusion factories, forging elements in their incredibly hot cores. X-rays and Gamma rays are emitted as a byproduct of this process, but their movements to the surface aren’t straight or easy—the journey could take them tens of thousands of years. The Sun’s core is so dense that the radiation continually hits other atoms, travelling only a few millimetres before being absorbed and then re-emitted over and over again, zig-zagging its way out like a drunk staggering home.

Slowly, the photons work their way up through various layers, including the radiative zone, where they are remitted at longer wavelengths and therefore gradually converted to visible light. Then they pass through the convective zone where the photons are absorbed by gas, heating it up and making it rise towards the surface where it creates the boiling effect we recognise so well.

Finally, after travelling 695,000 kilometres from the core, the photons burst free of the photosphere and into the vacuum of space, racing off at the ordinary speed of light: 300,000 kilometres per second.

It might seem like we’re getting fresh, new light down here on Earth, but in reality our skin is being kissed by photons born eons ago.

Scientists have found that memories may be passed down through generations in our DNA
New research from Emory University School of Medicine, in Atlanta, has shown that it is possible for some information to be inherited biologically through chemical changes that occur in DNA. During the tests they learned that that mice can pass on learned information about traumatic or stressful experiences – in this case a fear of the smell of cherry blossom – to subsequent generations.
According to the Telegraph, Dr Brian Dias, from the department of psychiatry at Emory University, said: ”From a translational perspective, our results allow us to appreciate how the experiences of a parent, before even conceiving offspring, markedly influence both structure and function in the nervous system of subsequent generations.

Do you agree that the planet Venus is warm because it has a lot of carbon dioxide in its atmosphere? And when I say ‘warm,’ I mean ‘hot enough to melt lead on the surface.’

fuckyeahfluiddynamics:

This high-speed video of a bullet fired into a water balloon shows how dramatically drag forces can affect an object. In general, drag is proportional to fluid density times an object’s velocity squared. This means that changes in velocity cause even larger changes in drag force. In this case, though, it’s not the bullet’s velocity that is its undoing. When the bullet penetrates the balloon, it transitions from moving through air to moving through water, which is 1000 times more dense. In an instant, the bullet’s drag increases by three orders of magnitude. The response is immediate: the bullet slows down so quickly that it lacks the energy to pierce the far side of the balloon. This is not the only neat fluid dynamics in the video, though. When the bullet enters the balloon, it drags air in its wake, creating an air-filled cavity in the balloon. The cavity seals near the entry point and quickly breaks up into smaller bubbles. Meanwhile, a unstable jet of water streams out of the balloon through the bullet hole, driven by hydrodynamic pressure and the constriction of the balloon. (Video credit: Keyence)

The saddest aspect of life right now is that science gathers knowledge faster than society gathers wisdom. — Isaac Asimov (via observando)

It’s lonely moments, such as these, that my mind wanders. It gets me to thinking about the past and what could have been. Fuck it though. I’ve got a life to live, and live it, I shall.
