...crocs was nothing unusual. Plenty of animals subscribe to the are-you-going-to-finish-that? school of eating, rarely waiting for the answer before trying to help themselves to someone else's meal. Even top predators like big jungle cats may spend as much time defending a kill as eating it, one of the reasons some of them will carry a carcass up into a tree before tucking...
...emergence of drug-resistant bugs like the one he is incubating falls partly on the rest of us. For years public-health officials have been raising the alarm about how our overreliance on antibiotics is breeding a generation of superbugs, increasingly resistant to the medicines designed to kill them. The problem has only gotten worse as antibiotic use has expanded to agriculture, where cattle, chicken and fish are routinely treated with the drugs to keep infectious diseases in check...
...that points to a fundamental weakness of current antibiotics. All exploit the fact that the best agents to kill bacteria come from other bacteria. Each species makes toxins that can either kill other species or arrest their growth, and existing antibiotics are modified versions of these natural defenses. But that is just the kind of biological arms race that microbes and other living things excel at adapting to. So researchers working on the next generation of antibiotics are taking advantage of new knowledge about bacterial genetics and a better understanding of the resistance process to stay one step ahead...
Treating humans with live viruses--even ones that shouldn't harm us--is always risky, so Fischetti decided to isolate just the bacteria-puncturing enzyme and use it to kill bacteria from the outside. So far, he has developed compounds against pneumococcus, streptococcus and anthrax and hopes to eventually treat infected patients by squirting the enzymes in nasal-spray form weekly...
...Brookings Institution at the end of May, the number of sectarian murders, carried out mainly by Shi'ite death squads against Sunnis, has risen noticeably in recent weeks after a drop-off that began in the latter part of February. Sectarian deaths are often described as "extra-judicial killings" (EJKs) and involve the abduction, torture and murder of the victim, with the body usually left on the street. In May, says the Brookings report, citing Joint Chiefs Chairman Gen. Peter Pace, there were roughly 700 EJKs across Baghdad. While still lower than the pre-surge figure of 800 in February...
