Group of compounds found in red wine, vegetables simulate benefit of low-calorie diet
Mice, rats, worms, flies, and yeast all live longer on a low-calorie diet, which also seems to protect mammals against cancer and other aging-related diseases. Now, in yeast cells, researchers at Harvard Medical School and BIOMOL Research Laboratories have for the first time found a way to duplicate the benefits of restricted calories in yeast with a group of compounds found in red wine and vegetables. One compound extended yeast life span by up to 80 percent. The molecules are also active in human cells cultured in the laboratory.
The findings are reported in the August 24 Nature advanced online edition. The research suggests a promising route to find and develop drugs to lengthen life and prevent or treat aging-related 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...
