Genomic Technology Detects Fetal Problems

Two new studies show the potential of a genomic technique to help spot abnormalities in fetuses that conventional methods canít. The technology might allow better planning for early interventions and prevention of stillbirth.

Brain Changes as Trust Rises With Age

Older adults are more likely than younger ones to perceive dishonest faces as trustworthy, according to a study of social judgments and brain activity. The findings may help explain why older people are more likely to fall victim to fraud.

Source of New Heart Cell Growth Discovered

A study in mice suggests that new heart cells arise from pre-existing heart cells and that the renewal process slows with age. The findings may lead to improved regenerative therapy for people with heart damage.

Gene Variations Linked to Lung Cancer in Non-Smokers

Researchers identified genetic regions that predispose Asian women whoíve never smoked to lung cancer. The finding provides evidence that lung cancer between smokers and never-smokers can differ on a fundamental level.
