Hands-on learning in the greenhouse
Hands-on learning in the greenhouse
A revamped lesson in plant diversity added a tour of the campus greenhouse for students in introductory biology courses. Greenhouse coordinator Samara Gray worked with Linda Robinson and Karl Siegert to enhance the curriculum, incorporating lessons about plant biology and taxonomy that rely on the wide range of specimens present.

This freaky robotic fish is powered by ‘blood’
James Pikul of the School of Engineering and Applied Science co-authored a study in which researchers developed a soft, robotic lionfish powered by a blood-like compound. “This robot blood is our first demonstration of storing energy in a fluid that is normally only used for actuation,” he said.

How the mind emerges from the brain’s complex networks
Danielle Bassett of the School of Engineering and Applied Science co-authored an article about network neuroscience, which allows us to see the origins of mental activity in the brain. One day, they write, “a neuroscientist who knew all the principles of brain function and everything about someone’s brain could predict that person’s mental conditions—the future, as well as the past, would be present inside the person’s mind.”

Domestication made dogs’ facial anatomy more fetching to humans
James Serpell of the School of Veterinary Medicine said humans may have bred dogs to appear more infantile over time. “We are innately predisposed to respond with a kind of nurturing behavior towards certain physical characteristics,” he said. “Over time, [humans selected] for traits that satisfy that parental nurturing response.”
