Genomic Technology Detects Fetal Problems
Two new studies show the potential of a genomic technique to help spot abnormalities in fetuses that conventional methods can’t. 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.

Forecasting Flu Outbreaks
Scientists were able to forecast seasonal flu outbreaks using an approach common to weather prediction. The accomplishment lays the groundwork for systems to help public officials better predict and prepare for outbreaks.
Gene Variations Linked to Lung Cancer in Non-Smokers
Researchers identified genetic regions that predispose Asian women who’ve never smoked to lung cancer. The finding provides evidence that lung cancer between smokers and never-smokers can differ on a fundamental level.
Old Habits Gone But Not Forgotten
A small region of the rat brain seems to control whether certain habits will continue or be replaced by new habits, according to a new study. The finding offers insights into the brain circuitry that creates and manages our habits.

Little Exercise Might Lengthen Life
A little physical activity can go a long way toward extending your life, regardless of your weight, a new study found.
Gene Therapy for Salivary Gland Shows Promise
An experimental trial showed that gene therapy can be performed safely in the human salivary gland. The accomplishment may one day lead to treatments for head and neck cancer survivors who battle with chronic dry mouth.
Technique Selectively Represses Immune System
Researchers devised a way to successfully treat symptoms resembling multiple sclerosis in a mouse model. With further development, the technique might be used to treat multiple sclerosis and other autoimmune disorders.
