Biomechanics, historical artwork

Biomechanics. Historical artwork of two humans bearing loads. This illustration is taken from De Motu Animalium (On Animal Motion, 1680) by Alfonso Borelli (1608-1679). The illustration demonstrates how the leg is a twin-lever system controlled by muscles in which the hip (D) and knee (C) are both pivots

Buckyball molecule, computer artwork

Buckyball molecule. Conceptual computer artwork that might represent research into, or hi-tech automated production of, buckyball molecules (white sphere). Buckyballs are fullerenes, structural types (allotropes) of carbon. This one has 60 carbon atoms, which are arranged in a spherical structure consisting of interlinking hexagonal and pentagonal rings. It is thought that one day the ability of buckyballs to trap atoms (pink) within them might benefit the medical community. For example, they may be used to deliver medicines to specific tissues and cells. Buckyballs can also be used to trap metallic elements. This means scientists can fine tune a buckyball's electronic properties, which may be useful in electronic devices and circuitry
