A magnetic folding robot arm can grasp and bend thanks to its pattern of origami-inspired folds and a wireless electromagnetic field. Credit: Wyss Institute at Harvard University The traditional Japanese art of origami transforms a simple sheet of paper into complex, three-dimensional shapes through a very specific pattern of folds, creases, and crimps.

Electrons rotate on their way through the chip in a spiral pattern. Adjustments in the voltage lead to changes in the wavelengths of this pattern and thus the orientation of the spin can be controlled. At a specific location (gray box) the electron spin has a different orientation depending on the voltage. Credit: University of

Besides affecting weight, scientists believe the timing of food consumption affects one’s circadian rhythms and may be the route by which dietary habits impact lifespan.

New findings will better help map out the brain’s speech regions. Credit: Adeen Flinker For 150 years, the iconic Broca’s area of the brain has been recognized as the command center for human speech, including vocalization. Now, scientists at UC Berkeley and Johns Hopkins University in Maryland are challenging this long-held assumption with new evidence

A recording site (grey dot) in a brain region responsible for social interaction showed clear differences in neural activity when the subject was talking to the life partner (green curve) vs. the physician (blue curve). Human speech comes in countless varieties: When people talk to close friends or partners, they talk differently than when they

At its peak intensity, waters off Tasmania were 2.9°C above expected summertime temperatures.

Study participants in a series of experiments conducted by Cameron Anderson, a professor of management at UC Berkeley’s Haas School of Business, and Aaron Lukaszewski, an assistant professor at Oklahoma State University, overwhelmingly equated physical strength with higher status and leadership qualities. The paper, “The role of physical formidability in human social status allocation,”is forthcoming

Beauty may not simply be in the eye of the beholder, but in his or her relational goals, suggests new research. Credit: © nanettegrebe / Fotolia Beauty may not simply be in the eye of the beholder, but in his or her relational goals — according to findings of research just published in Archives of

Shark model with the mouth on the left and shoulder bones to the right. With a bamboo shark, after food is swallowed the bones of the shoulder girdle (shown partially blue) move back, drawing food in farther. Credit: Ariel Camp et. al. Sharks don’t have tongues to move food through their mouths, so instead some

The study is published ahead of print in the American Journal of Physiology — Lung Cellular and Molecular Physiology.
