The elaborately detailed colors of cave painting horses in western Europe have been a source of wonder for many years. Were they imaginary drawings based on more “normal” horses the artists witnessed? Or did they represent actual animals that no longer exist in modern times?
New DNA analysis of prehistoric horses suggests that these elaborately patterned ponies may have actually run through Stone Age meadows.
About 25,000 years ago, humans began painting a curious creature on the walls of European caves. Among the rhinos, wild cattle, and other animals, they sketched a white horse with black spots. Although such horses are popular breeds today, scientists didn’t think they existed before humans domesticated the species about 5,000 years ago. Now, a new study of prehistoric horse DNA concludes that spotted horses did indeed roam ancient Europe, suggesting that early artists may have been reproducing what they saw rather than creating imaginary creatures.

Under the Microscope - A T-Cell Lays the Smack Down on a Cancer Cell
Cambridge University has a great series going that takes us under the microscope. Here’s an awesome new one that features a cytotoxic T-cell attacking a cancer cell.
This is a process that goes on in your body all the time, with T-cells like this acting as cellular sentries and eliminating diseased and haywire cells from your body (by destroying them, of course). Your body is a battlefield.
This video is sped up 92 times from the cell’s real speed.
Kelvin-Helmholtz Instability manifested in clouds.
It happens when two mediums (wind and cloud) meet at different velocities and produce waves. Sort of like blowing across a glass of water.

Winter is coming, and it’s always nice to explain how snowflakes form. =)
A snowflake is created when water vapor slowly freezes around a dust particle. The morphology of the snowflake depends on factors as :humidity and temperature that is created.
But, Why do snowflakes look the way they do?
Well, the chemical properties of atoms, dictate how they are arranged in a solid.
Water molecules have a V-shaped geometry, with an Oxygen atom at the vertex bonded with two Hydrogen atoms, protruding like a rabbit-ear antenna. The shape of the water molecule determines the geometry of its packing, which turns out to be an hexagon.
