Viral proteins may prevent bacterial infections

that target and kill only the species or strain of bacteria for which they were designed. They will not harm human cells or the beneficial microorganisms that live in the nasal passages and throat and help protect against other infections. The stre...
Study explores safety of low-dose radiation

armed with B. suis. But that stockpile was destroyed after the U.S. government halted its biowarfare program in 1969. Other countries also developed Brucella weapons during the Cold War. Claire M. Fraser, Ph.D., president and director of TIGR, said: ...

Study Shows Hereditary Legacy Of Radiation Exposure
Ever since the atomic bombs
dropped on Japan created the world's largestexperiment on the effects of radiation on humans, people have puzzled overnot only just what these effects could be, but also if they could be passedon to the children of those exposed. In the past, researc...
