Electromagnetic particle shower Featured Specialist Imaging Print

Electromagnetic particle shower

Electromagnetic particle shower. Particle tracks (moving from bottom to top) showing multiple electron-positron pairs created from the energy of a high-energy gamma ray photon produced by a neutrino collision. The positron is the anti-particle of the electron, and this process is called pair-creation. Electrons and positrons are charged particles and form these paired spirals as they curve away from each other in a magnetic field. As they do so, they radiate photons, which can in turn produce new electron-positron pairs. This shower of particle creation continues until the energy of the original photon is used up. The region shown here is about 2 metres tall

Colour SEM of phagocyte ingesting bacteria

Phagocytosis. Coloured scanning electronmicrograph of a polymorphonuclear white blood cellor leucocyte, attacking Bacillus cereus bacteria. The leucocyte (orange), part of thebody's immune system, is attaching to andengulfing the Bacillus cells (blue, rod-shaped). It uses enzymes to digest the bacteria.This process of engulfment and digestion is knownas phagocytosis. Highly mobile, phagocytic cellsmigrate to areas of tissue damage. However, theirnecessary enzymes are quickly depleted byphagocytic activity so they degenerate. Defunctcells accumulate in pus. Magnification x7, 300 at6x7cm size.

Lead ion collisions Featured Specialist Imaging Print

Lead ion collisions

Lead ion collisions. Particle tracks from the first lead ion collisions seen by the ALICE (a large ion collider experiment) detector at CERN (the European particle physics laboratory) near Geneva, Switzerland, on 7th November 2010. Each collision, produced after the ions had been accelerated to an energy of 287 TeV (tera electron volts) by the large hadron collider (LHC), leads to the production of thousands of subatomic particles. The tracks are colour-coded according to energy from low (blue) to high (red). Lead ion collisions are expected to produce quark-gluon plasma, a primordial state of matter thought to have been present in the Universe microseconds after the Big Bang
