LIAI scientists make important finding on cytomegalovirus transmission

...It significantly reduced the virus load in all the animals and in 50 percent of them it completely eliminated it," Croft said. The OX40 treatment also greatly reduced the virus load, but did not eliminate it in any of the animals. The findings of the Ware and Croft team parallel those of LIAI researcher ...

Species thrive when sexual dimorphism broadens their niches

..., usually males. So we asked a simple question: If animals are adapting to their environment, but the sexes are different, does the sexual variation add to diversity? In other words, is it important to consider both sexes? The answer is yes." Butler, Sawyer, and Losos modeled the "morphospace" -- a gauge o...

Research suggests men's sexual behavior adapts to perceived threats

...Although many people are familiar with the idea of animals competing for mates before sex occurs, through mating displays such as bright feathers or butting antlers, we are finding more evidence that there is also competition after mating occurs," says author Todd K. Shackelford. "An alternative way of think...
