   Platelet factor 4
   `Platelet factor 4` (PF4) is a small cytokine belonging to the CXC chemokine family that is also known as `chemokine (C-X-C motif) ligand 4` (CXCL4) . This chemokine is released from alpha-granules of activated platelets during platelet aggregation, and promotes blood coagulation by moderating the effects of heparin-like molecules. Due to these roles, it is predicted to play a role in wound repair and inflammation. It is usually found in a comple...

    Plutonium-244
    Plutonium-244 has a halflife of 80 million years. This is longer than any of the other isotopes of plutonium, and in fact longer than any actinide except for the three naturally abundant ones U-235 (700my), U-238, and Thorium-232, and longer than any other isotopes except samarium-146 (103my), potassium-40 (1.25by), and a number of nearly stable isotopes with halflives much longer than the age of the universe. Some studies have claimed to detect...
