The unique mechanism of anti-HSV activity of NP-1 suggests that it may be useful alone, or in combination with other candidate agents, in the development of multitargeted co...Perlegen scientists find genetic basis for difference between humans and non-human primates

This protein ejects the antibiotics trapped in the AcrB cavity. If it's blocked, the pump can't work. As McDermott explains, perhap...Monogamous animals may be more likely to die out

Similarly, several colobus monkey species, which have few mates, died out an average of 18 years after the reserves were established, while green monkeys and baboons, which have many mates, are still living in all the reserves.
