Hendra and the closely related Nipah virus, both rare viruses that are part of the NIH biodefense research program, target the lungs and brain and have human case fatality rates of 60 percent and more than 75 percent, respectively. These diseases in monkeys mirror what happens in humans, and the study results are cause for hope that the antibody, named m102.4, ultimately may be developed into a possible treatment for people who become infected with these viruses.

For a long time it was thought that humans, with our relatively long life spans and access to modern medicine, aged more slowly than other animals. Early comparisons with rats, mice, and other short-lived creatures confirmed the hunch. But now, the first-ever multi-species comparison of human aging patterns with those in chimps, gorillas, and other primates suggests the pace of human aging may not be so unique after all.

They designed the particles to mimic the immune-stimulating effects of one of the most successful vaccines ever developed -- the yellow fever vaccine. The particles, made of biodegradable polymers, have components that activate two different parts of the innate immune system and can be used interchangeably with material from many different bacteria or viruses.
