A person's facial expressions and mood can be misperceived due to differences in facial features such as eyebrow shape, eyelid position and wrinkles, according to a U.S. study.

It included 20 health care workers who viewed photos that were digitally altered to change a number of features. The participants were asked to rate, on a scale of 0 to 5, seven expressions or emotions conveyed in the photos: tiredness, happiness, surprise, anger, disgust, fear and sadness, United Press International reported.

The findings were presented Wednesday during the American Thoracic Society's International Conference, in Toronto.

(HealthDay News) -- If an expectant mother is exposed to high levels of stress, her baby may be more likely to develop asthma or allergies later in life, new research suggests.

Babies born to mothers experiencing high levels of stress had more IgE in their blood at birth than did babies born to less-stressed moms. IgE is an antibody involved in allergic and asthmatic reactions.
