(A) The in situ adhesion process of UIHA underwater, (B) the chemical reaction scheme inside UIHA and at the interface between UIHA and substrate, and (C) the proposed biomedical applications of UIHA. Unlike small molecules, gelation of macromolecular fluids shows obvious...
by Brian Burns, Massachusetts General Hospital Hospitalized patients who report an allergy to penicillin are often prescribed alternative antibiotics for infection that can be harmful, even though diagnostic testing or evaluations would show that the vast majority of these reported allergies could be disproven, according to researchers from Massachusetts General Hospital.

A team of researchers at the University of Minnesota have, for the first time, fully 3D printed an array of light receptors on a hemispherical surface. This discovery marks a significant step toward creating a “bionic eye” that could someday help blind people see or sighted people see better. The research is published today in Advanced Materials, a peer-reviewed scientific...
