Genes, worms and the new genetics
A surprising finding over the past 20 years is that all animals have many of the same genes and that they use them in similar ways to grow and develop. These similarities mean that much of what is learned about what genes do in simple animals such as....

Like his nineteenth century contemporaries David Ferrier tried to reveal cerebral localisation of function by direct electrical stimulation of the exposed brain of animals. With some notable exceptions the results were disappointing and confined to t....

An evolutionary development of perception is suggested - from passive reception to active perception to explicit conception - earlier stages being largely retained and incorporated in later species. A key is innate and then individually learned knowl....

Flowers are such a ubiquitous and familiar part of our modern world that it is easy to take them for granted. But as Darwin recognized, the exquisite details of their structure and appearance have been shaped by evolutionary processes over millions o....

Recent underwater images show that the deep sea realm of the British Isles is nothing like the monotonous expanse of mud that many people imagine. Spectacular coral reefs, once thought to be restricted to the tropics, are now known to occur in the ch....

The information for synthesizing the molecules that allow organisms to survive and replicate is encoded in genomic DNA. In the cell, DNA is copied to messenger RNA, and triplet codons in the messenger RNA are decoded in the process of translation to ....

Research into ageing has been rejuvenated by the discovery of mutations in single genes that extend the lifespan of laboratory animals. Some of the signalling pathways involved, particularly the insulin/Igf-like pathway, have effects on lifespan acro....
