Particle tracks on galaxies

Particle tracks and cosmology. Computer illustration of subatomic particle tracks (white spirals) seen with galaxies behind them. The tracks result from charged particles moving through a bubble chamber containing a superheated liquid. Ionisation of the liquid by the particles causes it to boil, so that tracks of minute bubbles are left in their wake. Each particle makes a distinct track, such as the spirals made by electrons and positrons. Galaxies are independent groups of stars bound together by mutual gravitational attraction. Particle physics has revealed the basic structure of the atoms which form everything in the universe

F. colour SEM of trabeculae in spongy bone tissue

Cancellous bone. False-colour scanning electron micrograph of trabeculae in cancellous (spongy) bone tissue. Bone tissue is divided into compact and cancellous. The latter fills the interior of bones and the cavities between the trabeculae are occupied by bone marrow. Trabeculae are thin and composed of irregular lamellae of bone with lacunae containing osteocytes. Some of these lacunae are visible as tiny dark depressions. Osteblasts are the cells responsible for bone formation. Once they cease activity and become embedded in bone matrix they are called osteocytes. Magnification: x36 at 6x7cm size. x60 at 4x5ins
