In the study, scientists tested the thinking skills of 6,500 people with an average age of 72 from the Chicago area with different levels of education. The education level of people in the study ranged from eight years of school or fewer to 16 or more years of schooling. Interviews and tests about memory and thinking functions were given every three years for an average of 6.5 years.
At the beginning of the study, those with more education had better memory and thinking skills than those with less education. However, education was not related to how rapidly these skills declined during the course of the study.
The study found that results remained the same regardless of other factors related to education such as occupation and race and the effects of practice with the tests.
"This is an interesting and important finding because scientists have long debated whether aging and memory loss tend to have a lesser affect on highly educated people. While education is associated with the memory's ability to function at a higher level, we found no link between higher education and how fast the memory loses that ability," says study author Robert S. Wilson, PhD, with the Alzheimer's Disease Center at Rush University Medical Center in Chicago.

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...
