[单项选择]Some people have a more complicated sensory life than others. Most taste tuna only when they eat it. A few, though, taste it when they hear a particular word, such as "castanet". Others link the color red with the letter "S" or make some other inappropriate connection between stimulus and response. Such people are known as synaesthetes, and the phenomenon of synaesthesia has puzzled brain scientists since it was recognized over a century ago.
Most researchers in the field suspect synaesthesia is caused by crossed wires in synaesthetes’ brains, but until recently they have had no way to check this hypothesis. However, the development of a technique called diffusion-tensor imaging has changed that. And researchers at the University of Amsterdam have just applied it to the brains of 18 women (the sex more likely to experience synaesthesia) who have the most common form of the condition. This is called grapheme-color synaesthesia. It is a tendency to see letters and numbers in color.<
[单项选择]Some countries are more populous; some have more crime. But in no other country are crime fighters quite so knowledgeable about citizens as in Britain. On January 4th a boastful Home Office detailed the triumphs of the world’s biggest forensic DNA database, which holds samples from more than 5% of the entire population of England and Wales. Recent changes to the rules governing the database mean that it may eventually hold profiles from more than a fifth of all adults.
Once a country starts storing DNA samples from criminals it is hard to resist the urge to expand the collection. When the National DNA Database (NDNAD) was set up in 1995, samples could only be taken from those charged with "recordable" offences. If a suspect was not tried, or was freed, the sample had to be destroyed and the profile removed from the database.
That law was abandoned in 2001 , after two men who had been convicted of murder and rape had their cases overturned on appeal -the DNA evidence against t
