Physicists have discovered "stacked pancakes of liquid magnetism" that may account for the strange electronic behavior of some layered helical magnets. The materials in the study are magnetic at cold temperatures and become nonmagnetic as…

Paving the way for the fabrication of artificial hearts, bioengineers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have successfully created a biohybrid model of human ventricles. The fabrication of a…

Heart disease -- the leading cause of death in the U.S. -- is so deadly in part because the heart, unlike other organs, cannot repair itself after injury. That is why tissue engineering, ultimately including the wholesale fabrication of an…

Polymers, the basis of all plastics, usually do not have an ordered structure, in contrast to biopolymers such as proteins. A team of researchers has now developed a polymer that can be differentiated into folded (ordered) and unfolded…
