In 1-D, electrons cannot “pass each other”. Credit: Osaka University

A step for prediction of electronic properties of extremely-fine metal nanowires in next-generation semiconductors. In 1D, various exotic phenomena are predicted that are totally different from those in the 3D world in which we live. One of the reasons of this is that particles cannot pass each other in 1D.

Researchers in Japan and France artificially created such unique 1D nano electronic systems on the surface of a solid, and observed the 1D electronic state (energy and kinetic momentum of electrons) by analyzing photo-emitted electrons from the sample, and verified the electronic structure...

A cell nucleus from a normal, healthy brain is shown at left. The lamin nucleoskeleton forms the perimeter around the nucleus. By contrast, tunnel-like anomalies are evident in the nucleus of the Alzheimer’s disease-affected cell shown at right.

A new finding offers a insight into one of the earliest biological events of Alzheimer’s disease and is expected to open new avenues of study. Neuronal cell death in Alzheimer’s disease is linked to disruption of a lamin nucleoskeleton that surrounds the nucleus of the cells...

This retinal scan of a uveitis patient demonstrates retinal thickening (red) involving the central retina resulting in compromising vision. University of Iowa researchers recently recently used proteomics (protein profiling) to devise a successful treatment strategy for a patient with uveitis, a disease which can have many causes, making it particularly difficult to diagnose and treat effectively.

Protein analysis can make diagnoses more accurate and treatments better targeted to individual patients. Researchers have used personalized proteomics to devise a successful treatment for a patient with uveitis, a potentially blinding eye disease that can have many causes, making it particularly difficult to diagnose and treat effectively.

Why people lose their locks in old age may be related to the aging of hair follicle stem cells, two new studies suggest. Though it is known that mammals that live for longer lifespans lose their hair, the mechanisms underlying this fate have been a mystery. Hair follicle stem cells (HFSCs), which generate the sacs or follicles that produce hair, keep hair growth going repeatedly over time.
