...that nonetheless ripples through their economic decision-making. Still, there are benefits that balance the financial hardship: grandparents tutor young children while Mom and Dad work; they acculturate the youngest generation to the values of family and nation; they provide a sense of cultural continuity that helps bind a society. China needs to make obvious changes to its elder-care system as it becomes a wealthier society, but as millions of U.S. families make the brutal decision about whether to send aging parents into nursing homes, a bigger dose of the Chinese ethos may well be returning to America...
Increasing species numbers, however, may not be possible. The main hurdle, not surprisingly, is politics. The needs of a real conservation effort may require a level of animal protection beyond what is politically possible. That puts conservationists in a bind. Do they push for the tighter levels of protection that might successfully preserve endangered species or do they accept what is politically feasible? "We suggest that most vulnerable species are not really being managed for viability," writes Traill. "Rather, conservation targets in most cases merely aim to maximize short-term [species] persistence and fit with complex political and financial realities...
...became infected with HIV, compared with 74 who received a saltwater placebo, a barely significant difference. And while a lower risk of infection normally derives from a drop in the amount of virus circulating in the blood--with less virus floating around, there is less chance that HIV can bind to healthy cells--that did not happen in this study. Which means that although those who are vaccinated might be protected, they are still very infectious and can continue to spread HIV--not an ideal side effect of a vaccine meant to contain an infectious disease...
...study and will finance a larger study of the cocaine vaccine next year. In September, NIDA also granted $10 million for a clinical trial to the makers of NicVAX, a nicotine vaccine that works similarly to the cocaine vaccine - by stimulating the immune system to create antibodies that bind to drug molecules and prevent them from entering the brain. (Because people don't generally make natural antibodies to cocaine, the cocaine vaccine combines a cocaine molecule with an inactive cholera toxin; incidentally, the vaccine protects against cholera as well).

...legionaries. Bulls were sacrificed, laurel wreaths donned. Chariots bore the plundered loot of subjugated tribes, and captured barbarians were yanked along in chains. Some of the slaves had instructions to mutter "Memento mori" (Remember you are mortal) to their captors - an ironic note in a propaganda play designed to bind the Roman public to its leaders...
