Twenty-three years ago, an American philosophy professor named James Flynn discovered a remarkable trend: Average IQ scores in every industrialized country on the planet had been increasing steadily for decades. Despite concerns about the dumbing-down of society - the failing schools, the garbage on TV, the decline of reading - the overall population was getting smarter. And the climb has continued, with more recent studies showing that the rate of IQ increase is accelerating.
THE way patterns of shift work are organised could be causing major health problems, according to a pair of reports commissioned by the UK government body that regulates workplace safety.
The reports, prepared for the Health and Safety Executive (HSE), show that offshore oil workers adopting the most popular shift pattern have a higher risk of heart disease and diabetes. This pattern also makes workers more tired and inattentive, increasing the chance of accidents and mistakes.
The distractions of constant emails, text and phone messages are a greater threat to IQ and concentration than taking cannabis, according to a survey of befuddled volunteers.
Doziness, lethargy and an increasing inability to focus reached "startling" levels in the trials by 1,100 people, who also demonstrated that emails in particular have an addictive, drug-like grip.
The pursuit of it was written into the Declaration of Independence, but finding the causes and effects of that elusive "it" -- happiness -- has been notoriously difficult.
Chinese and American scientists have jointly discovered a way to prevent the HIV virus spreading through the body.
Experts from the University of Science and Technology of China say that their most important finding is a small-molecule compound.
The compound can occupy a gap in a human cell ordinarily attacked by the HIV virus, experts were quoted by China Youth Daily yesterday as saying.
Usually the HIV virus enters a cell through this gap and begins duplicating itself immediately.
