Vasectomy Reversed on Endangered Horse
National Zoo veterinarians successfully reversed a vasectomy on an endangered horse in an operation they described as the first of its kind.
The surgery was performed on a Przewalski's horse, a species native to China and Mongolia. The horse, Minnesota, had a vasectomy in 1999 while at another zoo. He came to the National Zoo in 2006, and scientists found that the horse had high genetic value.
The reverse vasectomy, performed in October, was the first to be carried out on a critically endangered species, zoo officials said.
Increased City Control of WASA Is Overturned
The U.S. Senate voted yesterday to overturn District laws passed last year that had increased the city's control over the D.C. Water and Sewer Authority but angered suburban officials.
The Senate action came after a similar vote in the House. The measure was aimed at two D.C. laws: one that assigned oversight of the agency to the city's chief financial officer and another that created a hiring preference for District residents.
The agency provides drinking water and sewage service to more than 500,000 customers in the District. It also provides sewage service to about 1.6 million people in parts of Montgomery and Prince George's counties, as well as Fairfax and Loudoun counties.
