  Researchers studying

313 healthy Vietnam

veterans have found that

anger, depression and

[5] hostility may increase the risk 

for cardiovascular disease,

diabetes and high blood

pressure.

Over a period of ten

[10] years, the men had regular 

physical examinations involving a wide variety of medical

tests. They also underwent psychological examinations

using well-established questionnaires to determine their

levels of hostility, anger and depression.

[15] The researchers measured blood levels of a protein 

called C3, a marker for the inflammation that is a risk

factor for cardiovascular illnesses. After controlling for

other variables, the scientists found that those in the

highest one-quarter in hostility, anger and depression

[20] showed a steady and significant increase in C3 levels, 

while those in the lowest one-quarter had no increase.

  Japanese researchers

have spent five years

developing a humanoid robot

system that can understand

[5] and respond to simultaneous

speakers. They posit a

restaurant scenario in which

the robot is a waiter. When

three people stand before the

[10] robot and simultaneously

order pork cutlet meals or

French dinners, the robot

understands at about 70

percent comprehension,

[15] responding by repeating each

order and giving the total price. This process takes less

than two seconds and, crucially, requires no prior voice

training.

  Such auditory powers mark a fundamental challenge

[20] in artificial intelligence – how to teach machines to pick out

significant sounds amid the hubbub. This is known as the

cocktail party effect, and most machines do not do any

better than humans who have had a few too many

martinis.
