‘Robotic blood’ powers and propels synthetic lionfish
‘Robotic blood’ powers and propels synthetic lionfish
Combining different functional components that are normally compartmentalized can lead to both powerful and lightweight future robots. A new paper by James Pikul highlights the success of a robotic lionfish that combines energy storage and movement through the use of a hydraulic liquid referred to as “robotic blood.”

Unraveling the brain’s reward circuits
Food, alcohol, and certain drugs all act to reduce the activity of hunger neurons and to release reward signals in the brain, but alcohol and drugs rely on a different pathway than does food.

Protein-linked sugars are crucial for the uptake of proteins linked to Parkinson’s disease
A new study shows that glycoproteins, proteins with added sugar molecules, impact how neurons uptake alpha-synuclein, a protein that clusters together and can lead to Parkinson’s disease.

What influences how parents and their gay adolescent sons talk about sexual health at home?
Research from Penn found that even when parent-child conversations avoid heteronormative stereotypes, outside factors like mass media and religion—those beyond the parents’ control—can reinforce them.

A new drug target for chemically induced Parkinson’s disease
A new drug target for chemically induced Parkinson’s disease
An enzyme that modifies chemicals formed in the body by alcohol, tobacco, and certain foods may be a new target for treating Parkinson’s disease. The altered compounds may play a role in triggering the onset or advancing the progression of the neurodegenerative condition.

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.”
