Researchers from the National Cancer Institute (NCI) have developed a mouse model of the premature aging syndrome known as Hutchinson-Gilford Progeria Syndrome (HGPS), according to a report appearing in the journal Nature. Researchers hope the mouse model will facilitate a better understanding of the fatal syndrome, as well as provide clues to the normal aging process.
Currently, there is no treatment for progeria, and children with the rare condition usually die of heart disease in their early teens. Although normal at birth, children with progeria begin to develop growth retardation, thinning skin, and fragile bones as young as 18 months.
"The similarities between mice with this particular mutation and patients with progeria are remarkable," said Colin Stewart, Ph.D., of NCIs Center for Cancer Research, the senior investigator on the study. "Now that weve identified the critical gene and have an animal model that mimics progeria, we have powerful tools for studying both the aging process and this devastating disease."

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.
In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...

For the first time, scientists have succeeded in studying the strength of hydrogen bonds in a single molecule using an atomic force microscope. Researchers from the University of Basel’s Swiss Nanoscience Institute network have reported the results in the journal Science Advances.
Hydrogen is the most common element in the universe and is an integral part of almost all organic compounds. Molecules and sections of macromolecules are...
