Staphylococcus aureus, an "elite force" in the bacteria battalion, is an adaptable organism that has always developed antibiotic resistance with haste. For example, staphylococcus aureus becomes resistant to erythromycin, a protein inhibitor, after only seven to ten days. Resistance to penicillin developed a few years after its commercial production in 1941, and resistance to four or more antibiotics became the norm for 40 percent of the strains by the end of the 1950s...
...HEAD START Using a few drops of spinal fluid, a new test can detect Alzheimer's disease years before full-blown symptoms arise. The test, which is as accurate as a brain autopsy, measures NTP, a protein that's released from damaged brain cells...

And with no elk carcasses lying around, scavengers like magpies, ravens and grizzly bears, accustomed to dining on scraps from wolf kills, have to scrounge elsewhere for protein. "The wolf is a keystone species," says Yellowstone biologist Douglas Smith. "You remove it and the effects cascade down to the grasses...
Gourmands need not apply. The protein-packed health bars that Sears peddles as ideal between-meal snacks taste like candy bars laced with sawdust.
