The popular dietary supplements glucosamine and chondroitin sulfate proved no better than a placebo in relieving osteoarthritis knee pain in most participants of a major national trial.

Obesity may affect response to asthma medications
A new study led by the University of Michigan suggests that people who are overweight or obese may have better results with the prescription pill sold as Singulair than with a type of inhaled steroid, while leaner people may have better luck with an inhaled steroid, called beclomethasone and sold as beclovent, vanceril and other brand names.

Children's self-esteem can affect their response to asthma
While many urban children suffer from asthma, those who have high self-esteem and good problem-solving skills may be less likely to have their asthma symptoms interfere with school, a new study finds.

Learning and memory stimulated by gut hormone
Researchers at Yale School of Medicine have found evidence that a hormone produced in the stomach directly stimulates the higher brain functions of spatial learning and memory development, and further suggests that we may learn best on an empty stomach.

Hundreds of earthquakes occur every day around the world, most of them underneath the oceans, while the vast majority of instruments used to record earthquakes are on land.

Cholesterol levels discounted as a biological marker for suicide risk among alcoholics
Alcoholism is a major risk factor for suicidal behavior. Prior research has suggested that cholesterol may be a general biological marker for suicide risk.

UF scientists reveal ancient origin of vertebrate skeleton
It turns out lampreys, long thought to have taken a different evolutionary road than almost all other backboned animals, may not be so different after all, especially in terms of the genetics that govern their skeletal development.

Genes involved in cell growth and cell division identified
A recent study shows that hundreds of genes contribute to cell growth and cell division.

Mobile lab expands capacity of animal disease diagnostics
In the event of a disease outbreak, a rapid, massive response by health officials is critical -- even if the patients are animals.

Binge drinkers have highest risk of alcohol-related injury
Moderate drinkers who occasionally drink heavily are more likely to suffer an alcohol-related injury than chronic heavy drinkers, a Swiss study has found, and the risk is greatest during a bout of binge drinking.

Hens' teeth not so rare after all
Scientists have discovered that rarest of things: a chicken with teeth - crocodile teeth to be precise.

Universities diffused Internet technology in mid-1990s
Universities played a unique role in the diffusion of Internet technology in the mid-1990s, according to a paper published in the March issue of the International Journal of Industrial Organization.

In a report in the March 2006 issue of The American Journal of Medicine, researchers from eight university and hospital health centers and Pfizer Inc present the results of a large, multinational,

Snakes poisoned at birth
Scientists in Germany have found that a significant route of transmission of Salmonella in non egg-laying snakes is from the mother to the offspring during pregnancy and birth.
