Dallas (Texas, US), July 9 : The Dallas Police Department has cut back on some of the additional protection that the department provided around the Preston Hollow home of former President George W. Bush.

The estimated cost of that service was 300,000 a year, according to police officials who asked that they not be named.

London, September 29: Researchers at the University of Texas Southwestern Medical Center in Dallas have identified an enzyme that can prevent secondary illnesses among people hit by bacterial infections.

Research leader Robert Munford points out that the mammalian immune system goes into a "tolerant" state during an infection, and its ability to fight off other invaders decreases.

The state persists even after the bacteria have been killed, he adds.

The researcher says that removing a molecule released by bacteria called lipopolysaccharide (LPS), which initiates tolerance, may help return the immune system to its normal state.
