DNA variations surprise researchers
... three million single nucleotide changes scattered amongst the chromosomes. The new data from the Sick Kids and Harvard groups revealed 255 regions (comprising more than 0.1 per cent) of the genome where large chunks of DNA are present in different copy numbers between individuals. Over 50 per cent of these ...Institute for OneWorld Health nominated for the 2004 World Technology Awards

... excitatory neurons, which pass electrical signals amongst themselves and act as the brain's wiring. The role of inhibitory interneurons, on the other hand, is to dampen the activity of excitatory neurons. The NPAS1 and NPAS3 proteins are transcription factors that can activate or deactivate other genes....Stuck on you: Scientists lay bare secrets of bacterial attachment proteins
...Their work helps to resolve a long-standing debate amongst microbiologists; it leads to the reclassifying of the Dr Adhesins into a group of bacterial protein appendages known as 'fimbriae'. These appendages are very difficult to see using the available electron microscopy techniques, and were originally cl...
