Instead of dismissing grumblings about being tired or exhausted, people should take these complaints seriously before they lead to a worsened health state or even death, says a University of Alberta researcher investigating fatigue.

Dr. Karin Olson, a U of A professor from the Faculty of Nursing, argues that there are differences between tiredness, fatigue and exhaustion and that recognizing those distinctions will help health-care workers create better treatment plans for their patients.

Sitting down to a family meal more often and cutting down on television watching can help keep children from becoming overweight, according to a new University of Missouri-Columbia study.

After following 8,000 children from kindergarten to third grade, researchers concluded that kids who watched the most TV were at the greatest risk of being or becoming overweight. Children who ate fewer meals with their families also were at risk for becoming overweight.


Common sense used to be more common

Heartbeat and breathing cycles can become synchronized, a new study shows.

Looking for patterns in the sequence of human heartbeats is a much studied subject; evidence for pattern-revealing characteristics such as chaos and fractal or spiral geometry have been sought. Breathing, which is more under direct conscious control than heartbeat, is much less studied.

Garlic has been hailed a wonder drug for centuries and has been used to prevent gangrene, treat high blood pressure, ward off common colds and is even believed by some to have cancer-fighting properties.

Now, scientists at The University of Nottingham are leading a new pilot study to see if the pungent bulb could also hold the key to preventing cystic fibrosis patients from falling foul of a potentially-fatal infection.

The research will look at whether taking garlic capsules can disrupt the communication system of the pathogen Pseudomonas to prevent illness from taking hold.

Sometimes it is better to follow the advice of others rather than your own mind even though you seem to have things under control. Not only humans but also fish follow this doctrine as shown by ecologists Jörgen Johnsson and Fredrik Sundström of Göteborg University, Sweden, in the journal Ethology.

They allowed European minnows to learn the correct route through a maze to obtain food in the presence or absence of a predatory brown trout. Then a naïve minnow joined the group on later trials either in the presence or absence of the trout.
