Many congestive HF-associated physiological changes were also suppressed, but the mechanisms aren’t known; level of exercise is critical but results come despite antecedent hypertension
A classic clinical dilemma faces doctors treating patients with congestive heart failure (CHF): while exercise generally protects the normal heart from cardiovascular disease, will exercise potentially "improve the prognosis of patents with CHF, or (will it place) a further excessive demand on an already over-stressed myocardium"?
Thats how a new research paper poses the question, and its positive but still tentative results show: "Briefly we found that low intensity exercise training markedly delayed the onset of overt CHF without a reduction in antecedent hypertension. Additionally, we found that some, but not all, of the classic cellular and systemic physiological alterations normally associated with the development of overt CHF were attenuated with exercise training."

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...
