Wisconsin scientists find portal to show animals evolve

...ished through changes in the genetic switches that direct how genes work. "This is smoking gun evidence of how animal patterns evolve," says Sean B. Carroll, a UW-Madison professor of genetics and the senior author of the Nature paper. While discovered in flies, it is almost certain that the same mechan...

Experimental domestication of foxes yields clues to cognitive evolution

...ying domestication in dogs occurred as a result of direct selection for communicative ability or instead as a correlated by-product of breeding selection against fear and aggression toward humans. To better understand how dogs evolved their unusual social cognitive ability, the researchers studied an experi...

Falling ants glide back to trunk to avoid dangers of forest floor

... ants the only wingless insects known to actively direct their fall were first observed last year outside Iquitos, Peru, by insect ecologist Stephen P. Yanoviak of UTMB. While perched 100 feet up in the rainforest canopy waiting for mosquitoes to alight and feed on his blood, Yanoviak casually brushed off...

Mouse model of leukemia yields exciting therapeutic implications for rare childhood cancer

A new study provides direct evidence that mutations associated with certain forms of leukemia transform blood cells into abnormal cancer cells. The research, published in the February issue of Cancer Cell, examines the molecular signals involved in this transformation and sugge...
