Mobile phone radiation wrecks your sleep

Radiation from mobile phones delays and reduces sleep, and causes headaches and confusion, according to a new study.

The research, sponsored by the mobile phone companies themselves, shows that using the handsets before bed causes people to take longer to reach the deeper stages of sleep and to spend less time in them, interfering with the body's ability to repair damage suffered during the day.

The Human Brain: Detective of auditory and visual change

The human brain is capable of detecting the slightest visual and auditory changes. Whether it is the flash of a student's hand into the air or the faintest miscue of a flutist, the brain instantaneously and effortlessly perceives changes in our environment. Several studies have indicated, however, that even a small span of time in between pre- and post-change images can disturb the brain's ability to detect visual discrepancies.

"The pre-change scene must be memorized in some way," explained psychologists Laurent Demany, Wiebke Trost, Maja Serman and Catherine Semal from the University of Bordeaux and the French National Center for Scientific Research (CNRS). "In the visual domain, numerous experiments have shown that even a very short gap of less than 100ms can dramatically disrupt our ability to detect a local change in complex images. Following such a gap, local changes can be detected only in very simple images." This phenomenon is known as 'change blindness.'

Face facts: People don't stand out in crowds

Why is it difficult to pick out even a familiar face in a crowd? We all experience this, but the phenomenon has been poorly understood until now. The results of a recent study may have implications for individuals with face-recognition disorders and visual-attention related ailments - and eventually could help scientists develop an artificial visual system that approaches the sophistication of human visual perception.

The study is part of the recently completed Journal of Vision special issue titled "Crowding: Including illusory conjunctions, surround suppression, and attention". "Crowding" is a failure to recognize an individual object in a cluttered environment. It may be due to one of the shortcuts our brains use to help us make sense of the vast amount of visual information we take in every second.


Cholesterol-lowering drug linked to increased risk of heart attack

Another belated disclosure from the pharmaceutical industry

Under pressure from media reports, consumer groups and federal investigators, pharmaceutical giant Merck and its partner Schering-Plough released the findings of a long-withheld company-sponsored study of the cholesterol-lowing drug Zetia this week. The study, completed in April 2006, reveals that companies had been falsely marketing the drug as an effective part of heart disease prevention. Moreover, the data indicate a link between the drug - taken by about a million Americans - and increased risk of heart attacks and strokes.

Comment: The question to ask is: Is there more money to be made from sickness or from health?

For health clubs and fitness centers, health is lucrative. For the medical industry and the pharmaceutical industry, sickness is more lucrative.

Drug companies suppress trials
