The ageing of cells may be due to errors that harm protein production

Older cells may fail to make proteins or may make proteins that don't function as they should, in a discovery that could lead to new drug targets to slow the ageing process

Male XY chromosomes, artwork. The Y chromosome (right) is found in males and is shorter than the X chromosome (upper left). The latter has been labelled with a white glow that can represent a genetic mutation. An individual's sex is determined by the presence or absence of the Y chromosome. Women are XX, while men are XY. Chromosomes are a condensed form of the genetic material DNA (deoxyribonucleic acid), which condenses into chromosomes during cell replication. Each chromosome has two identical strands (chromatids), aligned in parallel and joined at the centromere.

E. coli bacterium. Coloured transmission electron micrograph (TEM) of an Escherichia coli (E. coli) bacterium in the early stages of binary fission, the process by which the bacterium divides. This Gram-negative bacillus (rod-shaped) bacterium normally inhabits the human intestines. Under certain conditions it may undergo rapid division, which increases its numbers to such an extent that it causes infection. E. coli cause 80% of all urinary tract infections, travellers' diarrhoea and gastroenteritis in children. The hair-like appendages around the bacterium are pili, structures used for bacterial conjugation. Magnification: x17,500 at 6x7cm size.
