Hyperactive kids three times as likely to be removed from their families
Severely hyperactive children are three times more likely to be removed from their families, because their parents can no longer cope, than children with other mental health or behavioural problems, reveals research in Archives of Disease in Childhood.

Lack of specific collagen type leads to osteoarthritis
Duke University Medical Center researchers have found that joints whose cartilage lacks a specific type of collagen will develop osteoarthritis - the so-called

Air pollution thickens the blood
Air pollution, and especially particulate matter, thickens the blood and boosts inflammation, finds experimental research in Occupational and Environmental Medicine.

New approaches teach undergraduate students to think like researchers
A UC Santa Cruz professor has developed a teaching exercise for undergraduate biology classes to give students a sense of how scientists proceed when valid data appear to conflict.

U-M scientist to talk about tissue engineering at AAAS
Scientists have a pretty good handle on how to teach human cells to do tricks in a laboratory -- things like getting soft cells from the mouth's lining to form bone.

Ultra-cold temperature physics opens way to understanding and applications
Researchers doing ultra-cold temperature physics may not have to wear parkas, but they are producing the coldest temperatures ever and exploring model quantum systems that might lead to more accurate clocks and gyroscopes, quantum computers and communications as well as a better understanding of quantum physics phenomena.

New Georgia Tech micro-CT imaging technique to help tissue engineers improve bone regeneration
A new technique developed at Georgia Tech can help reveal better ways to heal and regenerate bones using microcomputed tomography (micro-CT) imaging.

Climate change to bring a wave of new health risks
According to Jonathan A. Patz, as the world's climate warms, and as people make widespread alterations to the global landscape, human populations will become far more vulnerable to heat-related mortality, air pollution-related illnesses, infectious diseases and malnutrition.

Psychiatric disorders greatly underdiagnosed in hospital emergency departments
New research offers dramatic evidence of how psychiatric disorders are underdiagnosed in hospital emergency departments, affecting an increasing number of Americans who rely on such facilities for much of their primary health care needs.

Cytoplasm affects the number of vertebrae in carp-goldfish clones
When scientists created clones between common carp and goldfish, the offspring appeared virtually identical to the species that provided the nucleus, but the cloned fish possessed the same number of vertebrae as the species that provided the enucleated egg cytoplasm.
