May 18 is HIV Vaccine Awareness Day.
This annual observance is a day to recognize and thank the thousands of volunteers, community members, health professionals, and scientists who are working
together to find a safe and effective HIV vaccine. It is also a day to educate our communities about the importance of preventive HIV vaccine research.
In recognition of HIV Vaccine Awareness Day, community activities and media events are being held around the country.
LifeScience Moment: Secretariat won the Preakness Stakes in record setting time.
On May 19, 1973 Secretariat won the Preakness Stakes in a record setting time of 1:53, a stakes
record that still stands today.
Secretariat, the record setting winner of the Triple Crown in 1973, had a heart estimated to be 22
pounds or two-and-three-quarters times as large as that of the average horse which is approximately 8.5 pounds.
Secretariat's Belmont Stakes victory by 31 lengths and a time of 2:24 flat, broke the stakes' record
by more than two seconds, aother record that still stands.
Secretariat's large heart can be genetically traced to the legendary Eclipse, foaled in
England for the Duke of Cumberland in 1764. The larger heart is passed down the female line on
the X chromosome.
Today, this genetic knowledge combined with ultrasound imaging technology helps breeders take
advantage of the X Factor.
