PHOTO: EAST NEWS/SCIENCE PHOTO LIBRARY Earth as a water drop, conceptual computer artwork. Earth depicted as a drop of water causing a splash in the 'cosmic ocean'. This could represent Earth's relative insignificance with respect to the scale of the universe.

PHOTO: EAST NEWS/SCIENCE PHOTO LIBRARY Earth's gravity well. Computer artwork of the Earth, showing its gravity well as a distorted grid below. A gravity well is the the gravitational potential field around a massive body. It is the pull of gravity that bodies such as planets and stars exert on their surroundings.

PHOTO: EAST NEWS/SCIENCE PHOTO LIBRARY Confocal light microscope, artwork. Confocal microscopy uses fluorescent dyes to highlight tissues, cellular structures and proteins in the samples being analysed. A laser beam (blue lines, source at left) is passed through a lens (blue oval) that focuses it on to a beam splitter (grey diagonal line). Some of the laser beams are directed to the sample (bottom right). The fluorescent dyes in the sample are excited by the laser beams and emit fluorescent light. This light passes back through the beam splitter and is collected by a digital camera. Laser beams directed towards the camera are removed by a filter (orange horizontal line).

PHOTO: EAST NEWS/SCIENCE PHOTO LIBRARY Scanning electron microscope (SEM), computer artwork. An SEM uses an electron beam (vertical yellow line) to obtain a three-dimensional image of an object at magnifications much higher than can be obtained using light waves. The beam is scanned over the sample (bottom left) in a vacuum, causing the emission of secondary electrons (diagonal yellow line). These secondary electrons are detected and used to form the image, which is displayed here on a screen.

PHOTO: EAST NEWS/SCIENCE PHOTO LIBRARY Graphene sheets, computer artwork. Graphene a single layer of graphite. It is composed of hexagonally arranged carbon atoms (spheres) linked by strong covalent bonds (rods). Graphene is very strong and flexible. It transports electrons highly efficiently and may one day replace silicon in computer chips and other technology applications. Graphene was discovered by Andre Geim in 2004.

PHOTO: EAST NEWS/SCIENCE PHOTO LIBRARY Bubble universes. Conceptual computer artwork of universes formed from the same Big Bang event. 'Big Bang' describes the expansion (inflation) of all matter from an infinitely compact state at the birth of the universe some 13.7 billion years ago. The inflation theory proposes that during the event, conditions known as a false vacuum produced a rapid expansion at faster than the speed of light. In this, areas of inflation formed 'bubbles' of matter that are completely isolated from each other and evolve independently in parallel to each other.

PHOTO: EAST NEWS/SCIENCE PHOTO LIBRARY Atomic structure. Conceptual computer artwork of electron orbit paths as rings around the central nucleus (yellow) of an atom. This is a classical schematic Bohr model of the atom. In quantum physics, it is thought that the electrons do not actually follow a defined orbit, but instead inhabit areas of probability around the nucleus.

PHOTO: EAST NEWS/SCIENCE PHOTO LIBRARY Nanorobots, computer artwork. Nanotechnology is an area of science concerned with producing mechanical entities on the scale of nanometres (billionths of a metre). It is hoped that robots of this size will one day be used internally for medical applications, such as the removal of cancerous cells, and the plaque that builds up in arteries causing atherosclerosis (heart disease).

PHOTO: EAST NEWS/SCIENCE PHOTO LIBRARY Nanorobots. Computer artwork of nanorobots dispersing from a capsule inside a human body. Nanotechnology is an area of science concerned with producing mechanical entities on the scale of nanometres (billionths of a metre). It is hoped that robots of this size will one day be used internally for medical applications, such as the removal of cancerous cells, and the plaque that builds up in arteries causing atherosclerosis (heart disease). They could theoretically be administered in a similar way to drugs, such as in capsules and tablets.

PHOTO: EAST NEWS/SCIENCE PHOTO LIBRARY Gravitational waves. Computer artwork of a massive object in space, showing gravitational waves as distortions of a grid surrounding it. A gravity wave is a fluctuation in the curvature of space-time which propagates as a wave, travelling outward from the source. Here the grid is used to represent space-time.

PHOTO: EAST NEWS/SCIENCE PHOTO LIBRARY Vacuum fluctuation. Computer artwork showing a particle and an antiparticle being created in a vacuum. A quantum vacuum is not empty, in it particle pairs are spontaneously created and lead a brief existence before annihilating one another. This process is known as vacuum, or quantum, fluctuation.
