Research from UNSW provides the most convincing evidence to date that complex mental activity across peoples lives significantly reduces the risk of dementia. The researchers found that such activity almost halves the incidence of dementia.
The paper, which has just been published in Psychological Medicine, is the first comprehensive review of the research in the field of brain reserve, which looks at the role of education, occupational complexity and mentally stimulating lifestyle pursuits in preventing cognitive decline. The paper integrates data from 29,000 individuals across 22 studies from around the world.
"Until now there have been mixed messages about the role of education, occupation, IQ and mentally stimulating leisure activities, in preventing cognitive decline. Now the results are much clearer," said the lead author, Dr Michael Valenzuela, from the School of Psychiatry at UNSW. "It is a case of use it or lose it. If you increase your brain reserve over your lifetime, you seem to lessen the risk of Alzheimers and other neurodegenerative diseases."

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
