Beauty and the brain

...umans have similar preferences for prototypes in a wide variety of other categories, including dogs, birds, fish, cars and even watches. Yet the question "why?" has remained open. A popular explanation has been an evolutionary, sexual-selection one that goes something as follows: Like symmetry (anothe...

Parasitic plants sniff out hosts

... and showed that the parasites were attracted to a wide variety of plants. They even found attraction to wheat plants, a poor host on which the dodder seedlings do not survive. However, when the researchers offered the seedlings a choice between wheat and tomato plants, the tomato won out, indicating th...

Haussler and postdoctoral fellow Gill Bejerano discovered the ultraconserved elements in 2003, and since then they have been trying to figure out how they arose and what function they serve. One ultraconserved eleme...

The shape of life: research sheds light on how cells take shape

...oteins are puny ?they measure only about 250 atoms wide ?but play critical roles in the body. Microtubules help cells divide. They also act as scaffolds, giving cells their shape, and serve as train tracks of sorts, moving important bits like chromosomes and mitochondria around inside of cells. As micro...
