The Facts of Cobalt
Cobalt element 27 is a chemical element.
•Cobalt is silvery-blue and brittle
•Cobalt blue glass beads in a Danish grave 3,400 years old. The same glass is found in ancient Egyptian tombs, including King Tutankhamen's, the researchers reported. The discovery hints at trade connections linking the two far-flung locations.
•Cobalt compounds are used In Many things including blue dye.
Supernova SN2014J, an exploding star 11 million light-years from Earth. The supernova emitted about 60 percent of the sun's mass in cobalt-56, the researchers reported in the journal Nature. The isotope has a half-life of 77 days and gradually decays into iron-56.
Cobalt is an essential trace nutrient for health. It makes up the backbone of vitamin B12, which is key to blood formation and the functioning of the nervous system.
• researchers in Denmark reported that they'd created a crystalline material that can draw oxygen from air, store it, and then release it as needed. Just 2.6 gallons (10 liters) of the material can suck all the air from a room, the researchers said. Just as iron is an essential ingredient in hemoglobin, the blood protein that snags oxygen from the lungs, cobalt is a key portion of this new material.
