This is one of the most satisfying videos ever taken

The tiger shares 95.6% of its genome with the domestic cat, from which it diverged about 10.8 million years ago

If you crane your neck and look up while standing in front of St Lambert's Church in Münster, Germany, you can make out three iron cages hanging from the church's steeple, just above the clock face.

The cages are empty, but five hundred years ago they held the mutilated, rotten corpses of three revolutionaries who led one of the most brutal Protestant revolutions in history.

I had to look twice!

It looks like it has a pulse!

Jellyfish have a complex life cycle that includes both a sexual stage and an asexual stage.

In the sexual stage, the body (called a medusa) produces gametes (eggs and sperm). Then the eggs fertilized by sperm develop into a free-swimming larval form called planula.

After a brief period floating about in surface waters, the larvae settle to the sea floor, attaching themselves to a rock or the seafloor. They develop into a polyp (asexual stage) and begin to feed and grow.

In spring, some of the polyps start to bud off immature jellyfish known as ephyra larvae. These grow into mature jellyfish.

Mount Teide is a volcano on Tenerife in the Canary Islands, Spain. Its summit is the highest point in Spain and the highest point above sea level in the islands of the Atlantic.

Hovering above the volcano there's a spectacular lenticular cloud. Lenticular clouds are stationary clouds that form mostly in the troposphere, typically in parallel alignment to the wind direction

This effect happens when the camera frame rate matches the helicopter's rotor RPMs. Each frame captures the blades quickly enough that they look like they are standing still

Left ventricular thrombus (LVT) is a blood clot (thrombus) in the left ventricle of the heart. LVT is a common complication of acute myocardial infarction (AMI). Typically the clot is a mural thrombus, meaning it is on the wall of the ventricle.

The primary risk of LVT is the occurrence of cardiac embolism, in which the thrombus detaches from the ventricular wall and travels through the circulation and blocks blood vessels.

Blockage can be especially damaging in the heart (infarction) or brain (stroke).
