SCIENTISTS from The University of Texas at Austin report in the journal Science that they have developed a new strategy to protect honey bees from a deadly trend known as colony collapse: genetically engineered strains of bacteria.

An increasing number of honey bee colonies in the U.S. have seen the dwindling of their adult bees. According to a national survey, beekeepers lost nearly 40% of their honey bee colonies last winter, the highest rate reported since the survey began 13 years ago.
