Health Alert: Pertussis in infants declining

(CBS) - Widespread vaccinations of teens are helping infants avoid a respiratory infection known as pertussis.

In 2006, the CDC recommended vaccinating all adolescents against pertussis and since then there's been a dramatic drop in the number of infants hospitalized with respiratory problems.   


Researchers say babies usually get respiratory infections from family members.   

(CBS) - New concerns are emerging about breast milk purchased online.

Researchers at Nationwide Children's Hospital found more than three-fourths of breast milk samples bought on the web contained bacteria that can make babies sick.

The study suggests the milk  may not be properly collected, stored or shipped.

(CBS) - Scientists at UCLA have discovered a biological clock in human genes that may one day help slow the aging process.

Researchers say the  internal clock accurately gauges the age of organs and tissues.

Eventually scientists hope this discovery will improve their understanding of what speeds up and slows down aging.
