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.
Parents should think twice before giving in to a middle-schooler's demands for a cell phone, some scientists say, because potential long-term health risks remain unclear.
Researchers have speculated for more than 10 years that the electromagnetic radiation emitted from cell phones may damage DNA and cause benign brain tumors, said Henry Lai, a bioengineering professor at the University of Washington.
"We don't know very much about the health effects of cell phone use on kids, but there are speculations," Lai said.
