Biometric fingerprint

Biometric fingerprint. Computer artwork of a hand and a fingerprint (upper centre). Fingerprints are the patterns of ridges on the tips of the fingers. They have combinations of features that are unique to individuals, and can be used to identify them. It is one of the oldest forms of biometrics, where body measurements are used to identify people. The more recent forms of biometrics include eye scans. Computer technology (which uses ones and zeros in a binary code to store data) has allowed the data in fingerprints to be digitised, speeding up the processes of comparison and identification

Fertility research

Fertility research. Conceptual computer artwork of a human egg cell and sperm cells overlaid with the banding pattern of a DNA (deoxyribonucleic acid) autoradiogram. This could represent research into the mechanisms of fertilisation, the process where one of the male sperm cells fuses its DNA (genetic material) with that of the female egg cell. The image could also represent research into inherited disease, and using artificial fertilisation (like IVF) to screen out damaged or undesirable genes. The bands of the autoradiogram represent the sequence of the nucleotide bases that form the genetic code found in DNA, and which contains the instructions for forming a new human
