Seeing the action involved in cell membrane hemifusion

Cells are biological wonders. Throughout billions of years of existence on Earth, these tiny units of life have evolved to collaborate at the smallest levels in promoting, preserving and protecting the organism they comprise. Among these functions is the transport of lipids and other biomacromolecules between cells via membrane adhesion and fusion...

Nanotechnology identifies brain tumor types through MRI 'virtual biopsy'

Biomedical researchers at Cedars-Sinai have invented a tiny drug-delivery system that can identify cancer cell types in the brain through “virtual biopsies” and then attack the molecular structure of the disease. If laboratory research with mice is borne out in human studies, the results could be used to deliver nano-scale drugs that can distinguish...

Computational physicists advance understanding of electrical vortices in certain materials

Computational physicists have developed a novel method that accurately reveals how electrical vortices affect electronic properties of materials that are used in a wide range of applications, including cell phones and military sonar. Zhigang Gui, a doctoral student in physics at the University of Arkansas, and Laurent Bellaiche, Distinguished Professor...

A new formulation of quantum mechanics

Quantum mechanics remains one of the most tested theory in the history of physics and yet it represents one of the most challenging theory human kind has come up with. While the Schrödinger formulation is the de-facto standard, describing systems in terms of wave-functions, it is certainly not the only...
