SEM (Scanning Electron Microscope) image of a white blood cell, platelet and red blood cell. White blood cells or leucocytes (far right) fight infection by producing antibodies or devouring invading bacteria. Red blood cells or erythrocytes (far left) carry oxygen from the lungs to the rest of the body. Platelets (middle) are cell fragments that play a role in the ability of blood to clot.
Video of Macropinna microstoma (barreleye fish): A deep-sea fish with a transparent head and tubular eyes. Video taken by unmanned, undersea robots called remotely operated vehicles (ROVs) to study barreleye fish in the deep waters just offshore of Central California. At depths of 600 to 800 meters (2,000 to 2,600 feet) below the surface. Very Cool.
