A leading stroke researcher says the aging of the American population means that more people are at risk for stroke, and unless new approaches are developed to reduce stroke incidence, it will surpass heart attacks and cancer as the major cause of long-term disability and premature death.
"…The heart will no longer be the cause of most sudden deaths, leaving behind an ever-growing population of the elderly disabled by stroke and vascular dementia …," writes James F. Toole, M.D., and colleagues from Wake Forest University Baptist Medical Center in an editorial in the current issue of the Journal of the American Medical Association (JAMA).
Toole, past president of the International Stroke Federation, says using ultrasound to screen people for narrowed arteries in the neck is the best way to identify people at excess risk for stroke. He recommends that men undergo a baseline ultrasound screening of their carotid arteries between the ages of 50 and 60, depending on their overall health. He says that both men and women with diabetes, hypertension or a family history of stroke – all of which increase the risk of stroke – should be screened even earlier.

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...
