Lead ion collision Featured 25 Jan 2014 Print

Lead ion collision

Particle tracks from a lead ion collision seen by the CMS (compact muon solenoid) detector at CERN (the European particle physics laboratory) near Geneva, Switzerland. Before the collision the ions had been accelerated by the large hadron collider (LHC). The central tracking chamber (cylindrical) and muon chambers (red rectangles) of the detector are seen end-on in outline. The collision produced a number of unidentified particles (orange) and an upsilon meson. The upsilon meson is not seen, but is revealed through its decay products; a pair of muons (two longest red lines). The green lines show the energy deposited by the muons in the detector's muon chambers. The energies of the unidentified particles are measured by the electrochemical calorimeter (shorter red lines) and the hadron calorimeter (blue)

Solar cell, monocrystalline, Micrograph Featured 25 Jan 2014 Print

Solar cell, monocrystalline, Micrograph

Solar cell. Light micrograph taken with episcopic lighting and Normarski Interference Contrast (DIC) of of a high performance solar cell made from a monocrystalline silicon wafer. When light hits it it releases electrons, which are converted into an electrical current. A grid of wires collects the electrons. Solar power is an environmentally-friendly energy source. It does not use up limited resources and does not release toxic waste products. Horizontal object size: approximately 0.6mm

Nervous system cells, artwork Featured 25 Jan 2014 Print

Nervous system cells, artwork

Nervous system cells. Computer artwork showing neurons (nerve cells, purple), astrocytes (green) and a blood vessel (along right). Neurons are responsible for passing information around the central nervous system (CNS) and from the CNS to the rest of the body. Each nerve cell comprises a body surrounded by numerous extensions called dendrites, which collect information from other nerve cells or from sensory cells. Each neuron also has one process called an axon, which passes information to other nerve cells, or to effector cells such as muscle fibres. The axons appear segmented as they are surrounded by a myelin sheath. Astrocytes provide support for the neurons. They surround and regulate synapses and supply neurons with nutrients
