Male lions use ambush hunting strategy

Washington, D.C.— It has long been believed that male lions are dependent on females when it comes to hunting. But new evidence suggests that male lions are, in fact, very successful hunters in their own right. A new report from a team including Carnegie’s Scott Loarie and Greg Asner shows that male lions use dense savanna vegetation for ambush-style hunting in Africa. Their work is published in Animal Behavior.  
 
Female lions have long been observed to rely on cooperative strategies to hunt their prey. While some studies demonstrated that male lions are as capable at hunting as females, the males are less likely to cooperate, so there were still questions as to how the males manage to hunt successfully. The possibility that male lions used vegetation for ambushing prey was considered, but it was difficult to study given the logistics and dangers of making observations of lions in densely vegetated portions of  the African savanna.  (more…)

Fluid Cathedrals: Gels Under the Microscope

ANN ARBOR— A dollop of hair gel might not look like much, but Michigan Engineering researchers have found that it’s a labyrinth of chambers and domes, constructed by the particles inside. These structures allow the gel to hold its shape and determine how much pressure it can withstand before it starts to flow.

While manufacturers currently use trial and error to develop gels with a particular degree of solidity, this discovery could provide a way to design gels for particular applications. (more…)
